Stacking up against alternative conceptions: using Uno cards to introduce discourse and argumentation

NASA Astrophysics Data System (ADS)

Dunac, Patricia S.; Demir, Kadir

2013-11-01

We engaged secondary science students in a teacher and student constructed Uno card game (UCG) to change their conceptual understanding of the various energy transformations. The paper outlines how we incorporated Toulmin’s argumentation pattern (Toulmin 1958 The Uses of Argument (Cambridge: Cambridge University Press)) in the UCG, using discourse (Erduran et al 2004 Sci. Educ. 88 915-33) and through a 5E learning cycle (Bybee 1997 Achieving Scientific Literacy: From Purposes to Practices (Portsmouth, NH: Heinemann Educational Books)). The activity helped students develop a deeper understanding of the energy transformation among and between different sources. Students experienced a conceptual gain in their ways of thinking, in contrast to traditional teaching and learning practices. The collaboration and interaction between teacher-student(s) and between students fostered an environment where they became co-constructors of knowledge.

Patterns in Students' Argumentation Confronted with a Risk-focused Socio-scientific Issue

NASA Astrophysics Data System (ADS)

Kolstø, Stein Dankert

2006-11-01

This paper reports a qualitative study on students’ informal reasoning on a controversial socio-scientific issue. Twenty-two students from four science classes in Norway were interviewed about the local construction of new power lines and the possible increased risk of childhood leukaemia. The focus in the study is on what arguments the students employ when asked about their decision-making and the interplay between knowledge and personal values. Five different types of main arguments are identified: the relative risk argument, the precautionary argument, the uncertainty argument, the small risk argument, and the pros and cons argument. These arguments are presented through case studies, and crucial information and values are identified for each argument. The students made use of a range of both scientific and non-scientific knowledge. The findings are discussed in relation to possible consequences for teaching models aimed at increasing students’ ability to make thoughtful decisions on socio-scientific issues.

Framing new research in science literacy and language use: Authenticity, multiple discourses, and the Third Space

NASA Astrophysics Data System (ADS)

Wallace, Carolyn S.

2004-11-01

This article presents a theoretical framework in the form of a model on which to base research in scientific literacy and language use. The assumption guiding the framework is that scientific literacy is comprised of the abilities to think metacognitively, to read and write scientific texts, and to apply the elements of a scientific argument. The framework is composed of three theoretical constructs: authenticity, multiple discourses, and Bhabha's Third Space. Some of the implications of the framework are that students need opportunities to (a) use scientific language in everyday situations; (b) negotiate readily among the many discourse genres of science; and (c) collaborate with teachers and peers on the meaning of scientific language. These ideas are illustrated with data excerpts from contemporary research studies. A set of potential research issues for the future is posed at the end of the article.

Chitnork, Amporn; Yuenyong, Chokchai

2018-01-01

The research aimed to enhance Grade 10 Thai students' scientific argumentation in learning about electric field through science, technology, and society (STS) approach. The participants included 45 Grade 10 students who were studying in a school in Nongsonghong, Khon Kaen, Thailand. Methodology regarded interpretive paradigm. The intervention was the force unit which was provided based on Yuenyong (2006) STS approach. Students learned about the STS electric field unit for 4 weeks. The students' scientific argumentation was interpreted based on Toulmin's argument pattern or TAP. The TAP provided six components of argumentation including data, claim, warrants, qualifiers, rebuttals and backing. Tools of interpretation included students' activity sheets, conversation, journal writing, classroom observation and interview. The findings revealed that students held the different pattern of argumentation. Then, they change pattern of argumentation close to the TAP. It indicates that the intervention of STS electric field unit enhance students to develop scientific argumentation. This finding may has implication of further enhancing scientific argumentation in Thailand.

Missed Opportunities for Science Learning: Unacknowledged Unscientific Arguments in Asynchronous Online and Face-to-Face Discussions

NASA Astrophysics Data System (ADS)

Callis-Duehl, Kristine; Idsardi, Robert; Humphrey, Eve A.; Gougis, Rebekka Darner

2018-02-01

We explored the scientific argumentation that occurs among university biology students during an argumentation task implemented in two environments: face-to-face in a classroom and online in an asynchronous discussion. We observed 10 student groups, each composed of three students. Our analysis focused on how students respond to their peers' unscientific arguments, which we define as assertions, hypotheses, propositions, or explanations that are inaccurate or incomplete from a scientific perspective. Unscientific arguments provide opportunities for productive dissent, scientific argumentation, and conceptual development of scientifically desirable conceptions. We found that students did not respond to the majority of unscientific arguments in both environments. Challenges to unscientific arguments were expressed as a question or through explanation, although the latter was more common online than face-to-face. Students demonstrated significantly more epistemic distancing in the face-to-face environment than the online environment. We discuss the differences in discourse observed in both environments and teaching implications. We also provide direction for future research seeking to address the challenges of engaging students in productive scientific argumentation in both face-to-face and online environments.

Building shared understandings in introductory physics tutorials through risk, repair, conflict & comedy

NASA Astrophysics Data System (ADS)

Conlin, Luke D.

Collaborative inquiry learning environments, such as The Tutorials in Physics Sensemaking, are designed to provide students with opportunities to partake in the authentic disciplinary practices of argumentation and sensemaking. Through these practices, groups of students in tutorial can build shared conceptual understandings of the mechanisms behind physical phenomena. In order to do so, they must also build a shared epistemological understanding of what they are doing together, such that their activity includes collaboratively making sense of mechanisms. Previous work (Conlin, Gupta, Scherr, & Hammer, 2007; Scherr & Hammer, 2009) has demonstrated that tutorial students do not settle upon only one way of understanding their activity together, but instead build multiple shared ways of understanding, or framing (Scherr & Hammer, 2009; Tannen, 1993a), their activity. I build upon this work by substantiating a preliminary finding that one of these shared ways of framing corresponds with increased evidence of the students' collaboratively making sense of physical mechanisms. What previous research has not yet addressed is how the students come to understand their activity as including collaborative sensemaking discussions in the first place, and how that understanding develops over the course of the semester. In this dissertation, I address both of these questions through an in-depth video analysis of three groups' discussions throughout the semester. To build shared understandings through scientific argumentation and collaborative sensemaking, the students need to continually make repairs of each other's understanding, but this comes with the risk of affective damage that can shut down further sensemaking discussions. By analyzing the discourse of the three groups' discussions throughout the semester, I show how each group is able to manage this essential tension as they each build and maintain a safe space to sensemake together. I find that the three groups differ in how soon, how frequently, and how deeply they engage in collaborative scientific sensemaking. This variability can be explained, in part, through differences in how the groups use hedging, irony, and other discourse moves that epistemically distance the speakers from their claims. This work highlights the connection between students' epistemology and affect in face-to-face interaction.

Advancing Competencies in Argumentation at Schools using the Example of "Culture-Environment Interaction"

Budke, A.; Schaebitz, F.; Dittrich, S.

2016-12-01

According to the German national education standards communication is one of the six areas in which competencies shall be conveyed in Geography classes. Special significance is given to the training of the competence to solve problems through argumentation. Argumentation has a great significance in the learning process in schools, because here the students' knowledge pools are individually linked and understood. According to modern theories of learning, learning is a constructive process. Linking existing pools of knowledge to new insights is usually triggered by communication and argumentation in the classroom. Furthermore, argumentation helps with the individual's formation of opinion as well as their identification with certain values. Argumentation is one of the central social and cultural techniques to solve conflicts peacefully, to conduct negotiations, and to act in one's own interests. Thus conveying competence in argumentation is to be seen as an interdisciplinary task in education. Recently a hypothetical model of competence in geographical argumentation was proposed, a methodical instrument for measuring competence in geographical argumentation was developed, and by analyzing textbooks it was shown that this topic is only marginally targeted by exercises. The Collaborative Research Center 806 "Our Way to Europe" (www.sfb806.uni-koeln.de), with its cross disciplinary research in the sciences as well as humanities offers an outstanding basis for developing and evaluating teaching material and concepts. The use of these diverse topics, complex systems, and the various research problems as well as findings of the CRC-806 allowed developing study units designed to promote problem solving and argumentation skills in the sciences and humanities. Here we will present the results of this study based on special teaching materials, which was tested and evaluated to support students in formulating scientific problems and promote their argumentation skills.

Constructing Scientific Arguments Using Evidence from Dynamic Computational Climate Models

NASA Astrophysics Data System (ADS)

Pallant, Amy; Lee, Hee-Sun

2015-04-01

Modeling and argumentation are two important scientific practices students need to develop throughout school years. In this paper, we investigated how middle and high school students ( N = 512) construct a scientific argument based on evidence from computational models with which they simulated climate change. We designed scientific argumentation tasks with three increasingly complex dynamic climate models. Each scientific argumentation task consisted of four parts: multiple-choice claim, openended explanation, five-point Likert scale uncertainty rating, and open-ended uncertainty rationale. We coded 1,294 scientific arguments in terms of a claim's consistency with current scientific consensus, whether explanations were model based or knowledge based and categorized the sources of uncertainty (personal vs. scientific). We used chi-square and ANOVA tests to identify significant patterns. Results indicate that (1) a majority of students incorporated models as evidence to support their claims, (2) most students used model output results shown on graphs to confirm their claim rather than to explain simulated molecular processes, (3) students' dependence on model results and their uncertainty rating diminished as the dynamic climate models became more and more complex, (4) some students' misconceptions interfered with observing and interpreting model results or simulated processes, and (5) students' uncertainty sources reflected more frequently on their assessment of personal knowledge or abilities related to the tasks than on their critical examination of scientific evidence resulting from models. These findings have implications for teaching and research related to the integration of scientific argumentation and modeling practices to address complex Earth systems.

Students' abilities to critique scientific evidence when reading and writing scientific arguments

NASA Astrophysics Data System (ADS)

Knight, Amanda M.

Scientific arguments are used to persuade others for explanations that make sense of the natural world. Over time, through the accumulation of evidence, one explanation for a scientific phenomenon tends to take precedence. In science education, arguments make students' thinking and reasoning visible while also supporting the development of their conceptual, procedural, and epistemic knowledge. As such, argumentation has become a goal within recent policy documents, including the Next Generation Science Standards, which, in turn, presents a need for comprehensive, effective, and scalable assessments. This dissertation used assessments that measure students' abilities to critique scientific evidence, which is measured in terms of the form of justification and the support of empirical evidence, when reading and writing scientific arguments. Cognitive interviews were then conducted with a subset of the students to explore the criteria they used to critique scientific evidence. Specifically, the research investigated what characteristics of scientific evidence the students preferred, how they critiqued both forms of justification and empirical evidence, and whether the four constructs represented four separate abilities. Findings suggest that students' prioritized the type of empirical evidence to the form of justification, and most often selected relevant-supporting justifications. When writing scientific arguments, most students constructed a justified claim, but struggled to justify their claims with empirical evidence. In comparison, when reading scientific arguments, students had trouble locating a justification when it was not empirical data. Additionally, it was more difficult for students to critique than identify or locate empirical evidence, and it was more difficult for students to identify than locate empirical evidence. Findings from the cognitive interviews suggest that students with more specific criteria tended to have more knowledge of the construct. Lastly, dimensional analyses suggest that these may not be four distinct constructs, which has important implications for curriculum development and instructional practice. Namely, teachers should attend to the critique of scientific evidence separately when reading and writing scientific arguments.

2014-02-01

This study explored teachers' use of the Argumentation and Evaluation Intervention (AEI) and associated graphic organizer to enhance the performance of students in middle and secondary science classrooms. The results reported here are from the third year of a design study during which the procedures were developed in collaboration with teachers. A quasi-experimental pretest-posttest design with 8 experimental and 8 control teachers was used with a total of 282 students. An open-ended test assessed students' abilities to evaluate a scientific argument made in an article. The students were asked to identify the claim and its qualifiers, identify and evaluate the evidence given for the claim, examine the reasoning in support of the claim, consider counterarguments, and construct and explain a conclusion about the claim. The quality of students' responses was assessed using a scoring rubric for each step of the argumentation process. Findings indicated a significantly higher overall score and large effect size in favor of students who were instructed using the AEI compared to students who received traditional lecture-discussion instruction. Subgroup and subscale scores are also presented. Teacher satisfaction and student satisfaction and confidence levels are reported.

Analysis of scientific argumentation in two physical chemistry classrooms using the POGIL approach

NASA Astrophysics Data System (ADS)

Moon, Alena C.

The benefits of facilitating argumentation in science education have been well reported (Jimenez-Aleixandre & Erduran, 2007). Engaging in argumentation has shown to model authentic scientific inquiry as well as promote development of content knowledge. However, less emphasis has been placed on facilitating argumentation in upper level undergraduate courses, though it is important for evaluating undergraduate curricula to characterize upper level students' scientific reasoning. This work considers two implementations of the POGIL physical chemistry curriculum and evaluates the classroom argumentation. The researchers aimed to consider the content of the arguments and dialectical features characteristic of socially constructed arguments (Nielson, 2013). To do this, whole class sessions were videotaped and Toulmin's Argument Pattern (TAP) was used to identify the arguments generated during the class (Erduran, Simon, & Osborne, 2004). A learning progression on chemical thinking (Sevian & Talanquer, 2014) was used as a domain-specific measure of argument quality. Results show differences in argumentation between and across both classrooms that can be explained by analysis of instructor facilitation and the POGIL curriculum. The results from this work will be used to make recommendations for instructor facilitation of argumentation and reform of the POGIL curriculum.

This study investigates the role of automated scoring and feedback in supporting students' construction of written scientific arguments while learning about factors that affect climate change in the classroom. The automated scoring and feedback technology was integrated into an online module. Students' written scientific argumentation occurred when they responded to structured argumentation prompts. After submitting the open-ended responses, students received scores generated by a scoring engine and written feedback associated with the scores in real-time. Using the log data that recorded argumentation scores as well as argument submission and revisions activities, we answer three research questions. First, how students behaved after receiving the feedback; second, whether and how students' revisions improved their argumentation scores; and third, did item difficulties shift with the availability of the automated feedback. Results showed that the majority of students (77%) made revisions after receiving the feedback, and students with higher initial scores were more likely to revise their responses. Students who revised had significantly higher final scores than those who did not, and each revision was associated with an average increase of 0.55 on the final scores. Analysis on item difficulty shifts showed that written scientific argumentation became easier after students used the automated feedback.

Inquiry laboratory activity and scientific argumentation in science education should be promoted and explicitly experienced by prospective biology teacher students in classes, including in microbiology courses. The goal of this study is to get information about perceptions of prospective biology teachers on scientific argumentation in microbiology inquiry lab activities. This study reported the result of a survey research to prospective biology teachers about how their perception about microbiology lab classes and their perception about inquiry and argumentation in microbiology lab activities should be. The participants of this study were 100 students of biology education department from an institute in Cirebon, West Java taking microbiology lecture during the fifth semester. The data were collected using questionnaire to explore the perceptions and knowledge of prospective biology teachers about microbiology, inquiry lab activities and argumentation. The result showed that students thought that the difficulties of microbiology as a subject were the lack of references and the way lecturer teaching. The students’ perception was that argumentation and inquiry should be implemented in microbiology courses and lab activities. Based on the data from questionnaire, It showed that prospective biology teacher students had very little knowledge about scientific argumentation and its implementation in science education. When the participants made arguments based on the problems given, they showed low quality of arguments.

Enhancing and Evaluating Scientific Argumentation in the Inquiryoriented College Chemistry Classroom

NASA Astrophysics Data System (ADS)

D'Souza, Annabel Nica

The research presented in chapters 2, 3, and 4 in this dissertation uses a sociocultural and sociohistorical lens, particularly around power, authority of knowledge and identity formation, to investigate the complexity of engaging in, supporting, and evaluating high-quality argumentation within a college biochemistry inquiry-oriented classroom. Argumentation skills are essential to college and career (National Research Council, 2010) and for a democratic citizenry. It is central to science teaching and learning (Osborne et al., 2004a) and can deepen content knowledge (Jimenez-Aleixandre et al., 2000; Jimenez-Aleixandre & Pereiro-Munhoz, 2002). When students have opportunities to make claims and support it with evidence and reasoning they may also increase their problem-solving and critical thinking capacity (Case, 2005; Willingham, 2007). Overall, this has implications in supporting students to become increasingly literate in scientific ideas, language, and practices. However, supporting argumentation can be challenging for instructors, particularly in designing leaning environments that facilitate and evaluate both the process and the product during student discussions (Duschl & Osborne, 2002). Fostering argumentation is complex and requires explicit modeling and multiple opportunities for dialogic interactions. This dissertation will examine how several facets influence argumentation in order to support instructors in implementing and improving argumentation in their inquiry-oriented classrooms. These facets include access to language and use of discursive moves, classroom design, curriculum and instructional activities, and interactional dynamics and power negotiation. The data set for this dissertation is a transcript generated from the audio- and video capture of a 7-minute student discussion around a mechanism in the TCA (TriCarboxylic Acid) cycle, as well as student writing, and course documents from student portfolios. This dissertation, organized using the manuscript style structure, will present three standalone chapters, each with a specific focus related to the central theme of supporting argumentation, which is the connecting thread. Chapter 2 will discuss how power is negotiated during the argumentation process and how interaction dynamics can support or inhibit the quality of argumentation. Chapter 3 will provide assessment and evaluation support to instructors who want to guide their students in meeting high quality levels in both the process and product of argumentation. Finally, chapter 4 will explore the influence of pedagogical, and instructional resources and tools on the quality of argumentation. This includes a discussion of the influence of classroom talk, particularly discursive moves and interactional dynamics, as well the curriculum and instructional activities, and the design features of the learning environment. Each chapter will conclude with instructional implications that provide practical guidance in the form of pedagogical activities to instructors. Partial funding for this dissertation was received from a PSC-CUNY Cycle 44 Research Award (66799-00 44). Findings suggest that the classroom design can support collaboration and the dialogic nature of argumentation, and the curriculum and activities can act as resources for students to share and negotiate multiple perspectives, but that instructors can also influence the process of argumentation by utilizing specific discursive moves, such as telling and revoicing, to promote or inhibit argumentation. The results, specifically from chapter 4, also propose that instructors model and share the expected criteria for high quality components of argumentation. The need for instructors to be aware of the criteria for high levels of quality for each of the argumentation components is a critical implication of this research. The criterion is presented in this dissertation and is derived from a review of multiple findings by researchers of argumentation, as well the scientific community at large. Creating structures and implementing targeted pedagogical strategies that support argumentation can lead students to use the process of argumentation as an empowerment tool to enact agency and negotiate power. This has the potential to sustain the success of science students, create a community of practice, and increase equity and access for all.

Orchestrating student discourse opportunities and listening for conceptual understandings in high school science classrooms

NASA Astrophysics Data System (ADS)

Kinard, Melissa Grass

Scientific communities have established social mechanisms for proposing explanations, questioning evidence, and validating claims. Opportunities like these are often not a given in science classrooms (Vellom, Anderson, & Palincsar, 1993) even though the National Science Education Standards (NSES, 1996) state that a scientifically literate person should be able to "engage intelligently in public discourse and debate about important issues in science and technology" (National Research Council [NRC], 1996). Research further documents that students' science conceptions undergo little modification with the traditional teaching experienced in many high school science classrooms (Duit, 2003, Dykstra, 2005). This case study is an examination of the discourse that occurred as four high school physics students collaborated on solutions to three physics lab problems during which the students made predictions and experimentally generated data to support their predictions. The discourse patterns were initially examined for instances of concept negotiations. Selected instances were further examined using Toulmin's (2003) pattern for characterizing argumentation in order to understand the students' scientific reasoning strategies and to document the role of collaboration in facilitating conceptual modifications and changes. Audio recordings of the students' conversations during the labs, written problems turned in to the teacher, interviews of the students, and observations and field notes taken during student collaboration were used to document and describe the students' challenges and successes encountered during their collaborative work. The findings of the study indicate that collaboration engaged the students and generated two types of productive science discourse: concept negotiations and procedure negotiations. Further analysis of the conceptual and procedure negotiations revealed that the students viewed science as sensible and plausible but not as a tool they could employ to answer their questions. The students' conceptual growth was inhibited by their allegiance to the authority of the science laws as learned in their school classroom. Thus, collaboration did not insure conceptual change. Describing student discourse in situ contributes to science education research about teaching practices that facilitate conceptual understandings in the science classroom.

Scientific reasoning skills development in the introductory biology courses for undergraduates

NASA Astrophysics Data System (ADS)

Schen, Melissa S.

Scientific reasoning is a skill of critical importance to those students who seek to become professional scientists. Yet, there is little research on the development of such reasoning in science majors. In addition, scientific reasoning is often investigated as two separate entities: hypothetico-deductive reasoning and argumentation, even though these skills may be linked. With regard to argumentation, most investigations look at its use in discussing socioscientific issues, not in analyzing scientific data. As scientists often use the same argumentation skills to develop and support conclusions, this avenue needs to be investigated. This study seeks to address these issues and establish a baseline of both hypothetico-deductive reasoning and argumentation of scientific data of biology majors through their engagement in introductory biology coursework. This descriptive study investigated the development of undergraduates' scientific reasoning skills by assessing them multiple times throughout a two-quarter introductory biology course sequence for majors. Participants were assessed at the beginning of the first quarter, end of the first quarter, and end of the second quarter. A split-half version of the revised Lawson Classroom Test of Scientific Reasoning (LCTSR) and a paper and pencil argumentation instrument developed for this study were utilized to assess student hypothetico-deductive reasoning and argumentation skills, respectively. To identify factors that may influence scientific reasoning development, demographic information regarding age, gender, science coursework completed, and future plans was collected. Evidence for course emphasis on scientific reasoning was found in lecture notes, assignments, and laboratory exercises. This study did not find any trends of improvement in the students' hypothetico-deductive reasoning or argumentation skills either during the first quarter or over both quarters. Specific difficulties in the control of variables and direct hypothetico-deductive reasoning were found through analysis of the LCTSR data. Students were also found to have trouble identifying and rebutting counterarguments, compared to generating initial arguments from scientific data sets. Although no overall improvement was found, a moderate, positive relationship was detected between LCTSR and argumentation scores at each administration, affirming the predicted association. Lastly, no difference was determined between biology majors and other students also enrolled in the courses. Overall, the results found here are similar to those classified in the literature for both hypothetico-deductive reasoning and argumentation, indicating that biology majors may be similar to other populations studied. Also, as no explicit attention was paid to scientific reasoning skills in the two courses, these findings complement those that illustrate a need for direct attention to foster the development of these skills. These results suggest the need to develop direct and explicit methods in order to improve the scientific reasoning skills of future biological scientists early in their undergraduate years.

Students' Argumentation Skills across Two Socio-Scientific Issues in a Confucian Classroom: Is transfer possible?

NASA Astrophysics Data System (ADS)

Foong, Chan-Choong; Daniel, Esther G. S.

2013-09-01

This paper argues the possible simultaneous development and transfer of students' argumentation skills from one socio-scientific issue to another in a Confucian classroom. In Malaysia, the Chinese vernacular schools follow a strict Confucian philosophy in the teaching and learning process. The teacher talks and the students listen. This case study explored the transfer of argumentation skills across two socio-scientific issues in such a Form 2 (8th grade) classroom. An instructional support to complement the syllabus was utilised. The teaching approach in the instructional support was more constructivist in nature and designed to introduce argumentation skills which is uncommon in a Confucian classroom. The two socio-scientific issues were genetically modified foods and deforestation. This paper presents a part of the bigger case study that was conducted. Data collected from written arguments were analysed using an analytical framework built upon Toulmin's ideas. The whole class analysis indicated progression in students' argumentation skills in their ability to give more valid grounds and rebuttals during the transfer. The individual analysis suggests progression in the majority of students' performance, while several students demonstrated non-progression when they faced a different socio-scientific issue.

Introducing Pre-university Students to Primary Scientific Literature Through Argumentation Analysis

NASA Astrophysics Data System (ADS)

Koeneman, Marcel; Goedhart, Martin; Ossevoort, Miriam

2013-10-01

Primary scientific literature is one of the most important means of communication in science, written for peers in the scientific community. Primary literature provides an authentic context for showing students how scientists support their claims. Several teaching strategies have been proposed using (adapted) scientific publications, some for secondary education, but none of these strategies focused specifically on scientific argumentation. The purpose of this study is to evaluate a strategy for teaching pre-university students to read unadapted primary scientific literature, translated into students' native language, based on a new argumentation analysis framework. This framework encompasses seven types of argumentative elements: motive, objective, main conclusion, implication, support, counterargument and refutation. During the intervention, students studied two research articles. We monitored students' reading comprehension and their opinion on the articles and activities. After the intervention, we measured students' ability to identify the argumentative elements in a third unadapted and translated research article. The presented framework enabled students to analyse the article by identifying the motive, objective, main conclusion and implication and part of the supports. Students stated that they found these activities useful. Most students understood the text on paragraph level and were able to read the article with some help for its vocabulary. We suggest that primary scientific literature has the potential to show students important aspects of the scientific process and to learn scientific vocabulary in an authentic context.

The Structure of Scientific Arguments by Secondary Science Teachers: Comparison of experimental and historical science topics

NASA Astrophysics Data System (ADS)

Gray, Ron; Kang, Nam-Hwa

2014-01-01

Just as scientific knowledge is constructed using distinct modes of inquiry (e.g. experimental or historical), arguments constructed during science instruction may vary depending on the mode of inquiry underlying the topic. The purpose of this study was to examine whether and how secondary science teachers construct scientific arguments during instruction differently for topics that rely on experimental or historical modes of inquiry. Four experienced high-school science teachers were observed daily during instructional units for both experimental and historical science topics. The main data sources include classroom observations and teacher interviews. The arguments were analyzed using Toulmin's argumentation pattern revealing specific patterns of arguments in teaching topics relying on these 2 modes of scientific inquiry. The teachers presented arguments to their students that were rather simple in structure but relatively authentic to the 2 different modes. The teachers used far more evidence in teaching topics based on historical inquiry than topics based on experimental inquiry. However, the differences were implicit in their teaching. Furthermore, their arguments did not portray the dynamic nature of science. Very few rebuttals or qualifiers were provided as the teachers were presenting their claims as if the data led straightforward to the claim. Implications for classroom practice and research are discussed.

Using Argument-Driven Inquiry to enhance students' argument sophistication when supporting a stance in the context of Socioscientific Issues

NASA Astrophysics Data System (ADS)

Grooms, Jonathon A.

This quasi-experimental study assesses the extent to which the Argument-Driven Inquiry (ADI) instructional model enhances undergraduate students' abilities to generate quality arguments supporting their stance in the context of a Socioscientific Issue (SSI) as compared to students experiencing a traditional style of instruction. Enhancing the quality of undergraduate students' arguments in the context of SSI can serve as an indirect measure of their scientific literacy and their ability to make sound decisions on issues that are inherently scientific but also involve social implications. Data collected in this study suggest that the undergraduate students experiencing the ADI instruction more readily provide rationales in their arguments supporting their decisions regarding two SSI-tasks as compared to a group of undergraduate students experiencing traditional instruction. This improvement in argument quality and gain in scientific literacy was achieved despite the overall lower SSI related content knowledge of the ADI students. Furthermore, the gap between the argument quality of those students with high versus low SSI related content knowledge was closed within the ADI group, while the same gap persisted post-intervention within the traditional instruction students. The role of students' epistemological sophistication was also investigated, which showed that neither instructional strategy was effective at shifting students' epistemological sophistication toward an evaluativist stance. However, the multiplists within the ADI group were able to significantly increase the sophistication of their arguments whereas the traditional students were not. There were no differences between the quality of arguments generated by the evaluativist students with either the treatment or comparison groups. Finally, the nature of the justifications used by the students revealed that the students (both comparison and treatment groups) did not invoke science-based justifications when supporting their stance, despite students' self-reports that scientific content knowledge accounted for the greatest influence on their stance, related to the SSI tasks. The results of this study suggest that the scientific habits of mind the students learned in the context of ADI investigations are transferred to the novel SSI contexts. Implications for the use of argument-based instructional models to enhance the generation of socioscientific arguments and to promote the development of scientific literacy are also discussed.

Teaching Real Data Interpretation with Models (TRIM): Analysis of Student Dialogue in a Large-Enrollment Cell and Developmental Biology Course

PubMed Central

Zagallo, Patricia; Meddleton, Shanice; Bolger, Molly S.

2016-01-01

We present our design for a cell biology course to integrate content with scientific practices, specifically data interpretation and model-based reasoning. A 2-yr research project within this course allowed us to understand how students interpret authentic biological data in this setting. Through analysis of written work, we measured the extent to which students’ data interpretations were valid and/or generative. By analyzing small-group audio recordings during in-class activities, we demonstrated how students used instructor-provided models to build and refine data interpretations. Often, students used models to broaden the scope of data interpretations, tying conclusions to a biological significance. Coding analysis revealed several strategies and challenges that were common among students in this collaborative setting. Spontaneous argumentation was present in 82% of transcripts, suggesting that data interpretation using models may be a way to elicit this important disciplinary practice. Argumentation dialogue included frequent co-construction of claims backed by evidence from data. Other common strategies included collaborative decoding of data representations and noticing data patterns before making interpretive claims. Focusing on irrelevant data patterns was the most common challenge. Our findings provide evidence to support the feasibility of supporting students’ data-interpretation skills within a large lecture course. PMID:27193288

Lee, Hee-Sun; Pallant, Amy; Pryputniewicz, Sarah

2015-08-01

Teaching scientific argumentation has emerged as an important goal for K-12 science education. In scientific argumentation, students are actively involved in coordinating evidence with theory based on their understanding of the scientific content and thinking critically about the strengths and weaknesses of the cited evidence in the context of the investigation. We developed a one-week-long online curriculum module called "Is there life in space?" where students conduct a series of four model-based tasks to learn how scientists detect extrasolar planets through the “wobble” and transit methods. The simulation model allows students to manipulate various parameters of an imaginary star and planet system such as planet size, orbit size, planet-orbiting-plane angle, and sensitivity of telescope equipment, and to adjust the display settings for graphs illustrating the relative velocity and light intensity of the star. Students can use model-based evidence to formulate an argument on whether particular signals in the graphs guarantee the presence of a planet. Students' argumentation is facilitated by the four-part prompts consisting of multiple-choice claim, open-ended explanation, Likert-scale uncertainty rating, and open-ended uncertainty rationale. We analyzed 1,013 scientific arguments formulated by 302 high school student groups taught by 7 teachers. We coded these arguments in terms of the accuracy of their claim, the sophistication of explanation connecting evidence to the established knowledge base, the uncertainty rating, and the scientific validity of uncertainty. We found that (1) only 18% of the students' uncertainty rationale involved critical reflection on limitations inherent in data and concepts, (2) 35% of students' uncertainty rationale reflected their assessment of personal ability and knowledge, rather than scientific sources of uncertainty related to the evidence, and (3) the nature of task such as the use of noisy data or the framing of critiquing scientists' discovery encouraged students' articulation of scientific uncertainty sources in different ways.

Supporting Teachers to Attend to Generalisation in Science Classroom Argumentation

In scientific arguments, claims must have meaning that extends beyond the immediate circumstances of an investigation. That is, claims must be generalised in some way. Therefore, teachers facilitating classroom argumentation must be prepared to support students' efforts to construct or criticise generalised claims. However, widely used argumentation support tools, for instance, the claim-evidence-reasoning (CER) framework, tend not to address generalisation. Accordingly, teachers using these kinds of tools may not be prepared to help their students negotiate issues of generalisation in arguments. We investigated this possibility in a study of professional development activities of 18 middle school teachers using CER. We compared the teachers' approach to generalisation when using a published version of CER to their approach when using an alternate form of CER that increased support for generalisation. In several different sessions, the teachers: (1) responded to survey questions when using CER, (2) critiqued student arguments, (3) used both CER and alternate CER to construct arguments, and (4) discussed the experience of using CER and alternate CER. When using the standard CER, the teachers did not explicitly attend to generalisation in student arguments or in their own arguments. With alternate CER, the teachers generalised their own arguments, and they acknowledged the need for generalisation in student arguments. We concluded that teachers using frameworks for supporting scientific argumentation could benefit from more explicit support for generalisation than CER provides. More broadly, we concluded that generalisation deserves increased attention as a pedagogical challenge within classroom scientific argumentation.

2018-06-01

J. D. Trout has recently developed a new defense of scientific realism, a new version of the No Miracles Argument. I critically evaluate Trout's novel defense of realism. I argue that Trout's argument for scientific realism and the related explanation for the success of science are self-defeating. In the process of arguing against the traditional realist strategies for explaining the success of science, he inadvertently undermines his own argument. Copyright © 2018 Elsevier Ltd.

Ethical muscle and scientific interests: a role for philosophy in scientific research.

PubMed

Kaposy, Chris

2008-03-01

Ethics, a branch of philosophy, has a place in the regulatory framework of human subjects research. Sometimes, however, ethical concepts and arguments play a more central role in scientific activity. This can happen, for example, when violations of research norms are also ethical violations. In such a situation, ethical arguments can be marshaled to improve the quality of the scientific research. I explore two different examples in which philosophers and scientists have used ethical arguments to plead for epistemological improvements in the conduct of research. The first example deals with research dishonesty in pharmaceutical development. The second example is concerned with neuropsychological research using fMRI technology.

Student performance on argumentation task in the Swedish National Assessment in science

Jönsson, Anders

2016-07-01

The aim of this study is to investigate the influence of content knowledge on students' socio-scientific argumentation in the Swedish National Assessment in biology, chemistry and physics for 12-year-olds. In Sweden, the assessment of socio-scientific argumentation has been a major part of the National Assessment during three consecutive years and this study utilizes data on student performance to investigate (a) the relationship between tasks primarily addressing argumentation and tasks addressing primarily content knowledge as well as (b) students' performance on argumentation tasks, which differ in relation to content, subject, aspect of argumentation and assessment criteria. Findings suggest a strong and positive relationship between content knowledge and students' performance on argumentation tasks. The analysis also provides some hypotheses about the task difficulty of argumentation tasks that may be pursued in future investigations.

Heating up the science classroom through global warming: An investigation of argument in earth system science education

NASA Astrophysics Data System (ADS)

Schweizer, Diane Mary

This research investigated how the use of argument within an earth system science perspective offers potential opportunities for students to develop skills of scientific reasoning. Earth system science views Earth as a synergistic system governed by complex interdependencies between physical and biological spheres. Earth system science presents familiar and compelling societal problems about Earth's environment thereby providing a highly motivational vehicle for engaging students in science. Using global warming as an application of earth system science, my research investigated how middle school and undergraduate students use scientific evidence when constructing and assessing arguments. This dissertation includes three related research studies. The first study took in place in three seventh grade science classrooms and investigated student engagement in a global warming debate. This study illustrated students used evidence to support their central argument; to negate the central argument of the opposing side; to present challenges to the opposing side; and to raise new questions. The second research study is a comparative study and investigated how other students under different instructional settings constructed their arguments on the cause of global warming from the same evidence. This study took place in two seventh grade science classrooms. This study demonstrated that when constructing personal arguments on global warming, students developed an earth system perspective as they considered and integrated different pieces of evidence. Students participating in debate where given a particular view to defend and focused on evidence matching this view, thereby displaying singular views of the cause of global warming. The third research study investigated students abilities to scientifically assess arguments. By analyzing students' written evaluations of arguments on the global climate presented during oral debates, this study demonstrated that undergraduates focus on the overall argument presentation with little attention given to the validity of specific argument components. The primary outcome of these studies is the recommendation that students be provided with opportunities to engage in a variety of argumentation practices, including, but not limited to, debate, constructing arguments reflective of personal views and assessing arguments. Closely coupled with this is the recommendation is that explicit instruction in scientific argumentation accompany classroom activities.

Utilizing public scientific web lectures to teach contemporary physics at the high school level: A case study of learning

NASA Astrophysics Data System (ADS)

Kapon, Shulamit; Ganiel, Uri; Eylon, Bat Sheva

2011-12-01

This paper describes a teaching experiment designed to examine the learning (i.e., retention of content and conceptual development) that takes place when public scientific web lectures delivered by scientists are utilized to present advanced ideas in physics to students with a high school background in physics. The students watched an exemplary public physics web lecture that was followed by a collaborative generic activity session. The collaborative session involved a guided critical reconstruction of the main arguments in the lecture, and a processing of the key analogical explanations. Then the students watched another exemplary web lecture on a different topic. The participants (N=14) were divided into two groups differing only in the order in which the lectures were presented. The students’ discussions during the activities show that they were able to reason and demonstrate conceptual progress, although the physics ideas in the lectures were far beyond their level in physics. The discussions during the collaborative session contributed significantly to the students’ understanding. We illustrate this point through an analysis of one of these discussions between two students on an analogical explanation of the Aharonov-Bohm effect that was presented in one of the lectures. The results from the tests that were administered to the participants several times during the intervention further support this contention.

Experts do play a particular role in public socio-scientific debates, even more so if they form heterogeneous coalition with other actors and experts. A case study about a public science education controversy surrounding the teaching of evolution/creationism in the UK press is used to investigate in detail how connections and coalitions between experts and other actors involved in the controversy emerged and played out. The research focuses on the question of what role collaborative and other networks of experts played in terms of influence, visibility, credibility, consensus and weight of argument. Issues that are considered in the research are the status of the members of the coalitions forming during the debate and how it is displayed in media representations and letters and petitions, and also how these networks and coalitions of experts perform in relation to each other.

The scientific argumentation profile of physics teacher candidate in Surabaya

NASA Astrophysics Data System (ADS)

Ain, T. N.; Wibowo, H. A. C.; Rohman, A.; Deta, U. A.

2018-03-01

The ability of scientific argumentation is an essential factor that must be mastered by physics teacher candidate as a requirement in explaining good and accurate scientific concepts. In the process of arguing, students develop explanations or persuade colleagues to support their hypotheses, express doubts, ask questions, relate alternative answers, and confirm what is unknown to develop the ability to provide rational and scientific explanations. The design of this research is descriptive qualitative with the subject of research is 20 undergraduate students of Physics Education Department in Surabaya. The research instrument consists of four casuistic questions related to the concept of kinematics. The argumentation pattern of physics teacher candidate is coded using Toulmin's argumentation pattern. The results show that the student’s ability in providing scientific argument is at the level of providing claims with the support of a weak warrant. The students are not able to provide excellent rebuttals. In each case given, the student can give a good claim statement in answering the questions. However, the concept used to support the claim is not correct. This case causes the warrant used to support the claim is weak. Students also do not analyse other facts that affect the system. Students have not reached a higher level because the understanding of physics is not deep enough.

Disconnections Between Teacher Expectations and Student Confidence in Bioethics

NASA Astrophysics Data System (ADS)

Hanegan, Nikki L.; Price, Laura; Peterson, Jeremy

2008-09-01

This study examines how student practice of scientific argumentation using socioscientific bioethics issues affects both teacher expectations of students’ general performance and student confidence in their own work. When teachers use bioethical issues in the classroom students can gain not only biology content knowledge but also important decision-making skills. Learning bioethics through scientific argumentation gives students opportunities to express their ideas, formulate educated opinions and value others’ viewpoints. Research has shown that science teachers’ expectations of student success and knowledge directly influence student achievement and confidence levels. Our study analyzes pre-course and post-course surveys completed by students enrolled in a university level bioethics course ( n = 111) and by faculty in the College of Biology and Agriculture faculty ( n = 34) based on their perceptions of student confidence. Additionally, student data were collected from classroom observations and interviews. Data analysis showed a disconnect between faculty and students perceptions of confidence for both knowledge and the use of science argumentation. Student reports of their confidence levels regarding various bioethical issues were higher than faculty reports. A further disconnect showed up between students’ preferred learning styles and the general faculty’s common teaching methods; students learned more by practicing scientific argumentation than listening to traditional lectures. Students who completed a bioethics course that included practice in scientific argumentation, significantly increased their confidence levels. This study suggests that professors’ expectations and teaching styles influence student confidence levels in both knowledge and scientific argumentation.

The Relationship Between Chinese Students' Subject Matter Knowledge and Argumentation Pedagogy

NASA Astrophysics Data System (ADS)

Wang, Jianlan; Buck, Gayle

2015-01-01

Science education in China is Subject Matter Knowledge (SMK) oriented in that SMK understanding is the major benchmark to assess students' achievement in science learning. Such an orientation causes students to overemphasize the memorization of SMK and neglect other indispensable components of science, such as scientific attitudes and research skills. The central government in China launched an educational innovation known as New Curriculum Reform in 2003. Considerable progress has been made in the past 11 years in regard to theoretical understandings and administrative priorities, but little progress has been made in terms of classroom instruction and scientific literacy cultivation at the secondary level. Under the pressure of nationwide standardized exams, any educational innovations are unlikely to be accepted unless there is robust evidence suggesting their efficacy in promoting students' achievements on exams, or even attempted unless teachers are assured such attempts will not negatively impact such achievement. Argumentation-integrated curriculum is one such innovation. Scientific argumentation is an essential scientific activity that leads to the development of an explanation based on empirical evidence. An initial foundation of SMK, in terms of the necessary background knowledge, is considered by many to be a vital component of argumentation and an enhanced SMK is one of the intended products of argumentation. The purpose of this sequential explanatory mixed methods study was to investigate the relationship between Chinese students' SMK levels and argumentation pedagogy and to provide insights into a possible research agenda focused on implementing argumentation in a heavily SMK-oriented context.

Translanguaging in a middle school science classroom: Constructing scientific arguments in English and Spanish

NASA Astrophysics Data System (ADS)

Licona, Peter R.

This dissertation investigates translanguaging in an English/Spanish dual language middle school science classroom as the teacher and students worked through a curriculum unit focusing on socioscientific issues and implementing a scientific argumentation framework. Translanguaging is the process in which bilingual speakers fluidly and dynamically draw from their full linguistic repertoire to perform a communicative act. Using ethnographically informed data collection in conjunction with discourse analysis, teacher translanguaging was examined for its related functions in the science classroom and how teacher translanguaging afforded opportunities for framing and supporting scientific argumentation. Results suggest that the functions of teacher translanguaging fell into three main themes: maintaining classroom culture, facilitating the academic task, and framing epistemic practices. Of the three categories of translanguaging, framing epistemic practices proved to be of paramount importance in the teacher presenting and supporting the practice of scientific argumentation. Implications from this study are relevant for pre-service science teacher preparation and in-service science teacher professional development for teachers working with emergent bilingual students.

Contemporary HIV/AIDS research: Insights from knowledge management theory.

PubMed

Callaghan, Chris William

2017-12-01

Knowledge management as a field is concerned with the management of knowledge, including the management of knowledge in research processes. Knowledge management theory has the potential to support research into problems such as HIV, antibiotic resistance and others, particularly in terms of aspects of scientific research related to the contribution of social science. To date, however, these challenges remain with us, and theoretical contributions that can complement natural science efforts to eradicate these problems are needed. This paper seeks to offer a theoretical contribution grounded in Kuhn's paradigm theory of innovation, and in the argument by Lakatos that scientific research can be fundamentally non-innovative, which suggests that social science aspects of knowledge creation may hold the key to more effective biomedical innovation. Given the consequences of ongoing and emerging global crises, and the failure of knowledge systems of scientific research to solve such problems outright, this paper provides a review of theory and literature arguing for a new paradigm in scientific research, based on the development of global systems to maximise research collaborations. A global systems approach effectively includes social science theory development as an important complement to the natural sciences research process. Arguably, information technology and social media technology have developed to the point at which solutions to knowledge aggregation challenges can enable solutions to knowledge problems on a scale hitherto unimaginable. Expert and non-expert crowdsourced inputs can enable problem-solving through exponentially increasing problem-solving inputs, using the 'crowd,' thereby increasing collaborations dramatically. It is argued that these developments herald a new era of participatory research, or a democratisation of research, which offers new hope for solving global social problems. This paper seeks to contribute to this end, and to the recognition of the important role of social theory in the scientific research process.

Integrating Scientific Argumentation to Improve Undergraduate Writing and Learning in a Global Environmental Change Course

DOE Office of Scientific and Technical Information (OSTI.GOV)

Koffman, Bess G.; Kreutz, Karl J.; Trenbath, Kim

We present a strategy for using scientific argumentation in an early undergraduate laboratory course to teach disciplinary writing practices and to promote critical thinking, knowledge transformation, and understanding of the scientific method. The approach combines targeted writing instruction; data analysis and interpretation; formulation of a hypothesis; and construction of an argument. Students submit and receive feedback on two drafts of two different argumentation essays, providing the opportunity for guided practice. Each written argument is intended to draw on several weeks' course material, including short lectures, discussions, readings, and problem sets. Thus our aim with these writing assignments is to helpmore » students synthesize content and concepts, deepening their learning. We have found that this inquiry-based approach to writing engages students in course material, and significantly improves both writing and learning. We observed the greatest improvement among students with the lowest initial scores, suggesting that lower-achieving students benefitted disproportionately from this approach. Students have responded positively to the use of writing in the course, many stating on course evaluations that this is the first time they have received instruction in scientific writing. They have also pointed to a greater 'big-picture' understanding of the course gained through writing. We describe the course and our curriculum, and provide suggestions for implementation as well as rubrics used to evaluate problem sets and student argumentation essays.« less

The Nature of Pre-service Science Teachers' Argumentation in Inquiry-oriented Laboratory Context

NASA Astrophysics Data System (ADS)

Ozdem, Yasemin; Ertepinar, Hamide; Cakiroglu, Jale; Erduran, Sibel

2013-10-01

The aim of this study was to investigate the kinds of argumentation schemes generated by pre-service elementary science teachers (PSTs) as they perform inquiry-oriented laboratory tasks, and to explore how argumentation schemes vary by task as well as by experimentation and discussion sessions. The model of argumentative and scientific inquiry was used as a design framework in the present study. According to the model, the inquiry of scientific topics was employed by groups of participants through experimentation and critical discussion sessions. The participants of the study were 35 PSTs, who teach middle school science to sixth through eighth grade students after graduation. The data were collected through video- and audio-recordings of the discussions made by PSTs in six inquiry-oriented laboratory sessions. For the analysis of data, pre-determined argumentation schemes by Walton were employed. The results illustrated that PSTs applied varied premises rather than only observations or reliable sources to ground their claims or to argue for a case or an action. It is also worthy of notice that the construction and evaluation of scientific knowledge claims resulted in different numbers and kinds of arguments. Results of this study suggest that designing inquiry-oriented laboratory environments, which are enriched with critical discussion, provides discourse opportunities that can support argumentation. Moreover, PSTs can be encouraged to support and promote argumentation in their future science classrooms if they engage in argumentation integrated instructional strategies.

Improving the argumentative skills of high school students through teacher’s questioning techniques and argumentative assessment

Kristianti, T. P.; Ramli, M.; Ariyanto, J.

2018-05-01

This research aims to know how students’ argumentative skills improved by applying teacher’s questioning techniques and argumentative assessment through collaborative action research between college student who did teaching practicum, biology teacher as tutor teacher, and lecturers. The action research was done in three cycles involving one class consisted of 36 eleventh graders. Lesson plans were developed collaboratively, and teaching practices were by the student teacher. In the reflective phase prior to the first cycle, learning processes were dominated by the teacher, hence students did not have sufficient opportunity to argue. Students were divided into two, 14 students were grouped as low achievement (LA) and 22 students were the high achievement (HA). Teacher questions and students’ responses were furtherly coded and interpreted following the validated rubric of level of argumentation. A divergent essay as an argumentative assessment was also tested to students at the end of each cycle. At the end of the third cycle, HA and LA students showed a significant change in argumentative skills responded the teacher’s questions. However, only four LA students who actively argued. Students from HA groups also showed the improvement on the level of argumentation, where they move from level 1 to 3.

An important goal of science education is to support development of citizens to participate in public debate and make informed decisions relevant to their lives and their worlds. The NGSS (Next Generation Science Standards) suggest engaging students in science classrooms in argumentation as a practice to help enhance the quality of evidence based decision making. In this multi-case study, we explored the use of written argumentation in eight secondary school science classrooms during a lesson on the relationship between ocean temperature and its CO2 holding capacity. All teachers of these classrooms were trained during a day long NSF funded Climate Literacy Workshop on the basic concepts of climate science, scientific practices and implementation of an activity called "It's a Gassy World". The data of the current study involved students' written arguments, teachers' written reflections on the implementation of the activity as well as field notes from the Climate Literacy Workshop. A qualitative discourse analysis of the data was used to find common themes around affordances and challenges of argument as a connective discourse for scientific practices to teach climate change. The findings show that participating in written argumentation process encouraged students to discuss their experimental design and use data interpretation for their evidences. However, the results also indicated the following challenges: a) teachers themselves need support in connecting their evidence to their claims, b) arguing a socioscientific issue creates a sensitive environment c) conceptual quality of an argument needs to be strengthen through background in courses other than science, and d) graphing skills (or lack of) can interfere with constructing scientifically accurate claims. This study has implications in effectively teaching climate change through argumentation, and thus creating opportunities for practicing authentic climate science research in K-12 classrooms.

Designing for students' science learning using argumentation and classroom debate

This research investigates how to design and introduce an educational innovation into a classroom setting to support learning. The research yields cognitive design principles for instruction involving scientific argumentation and debate. Specifically, eighth-grade students used a computer learning environment to construct scientific arguments and to participate in a classroom debate. The instruction was designed to help students integrate their science understanding by debating: How far does light go, does light die out over distance or go forever until absorbed? This research explores the tension between focusing students' conceptual change on specific scientific phenomena and their development of integrated understanding. I focus on the importance of connecting students' everyday experiences and intuitions to their science learning. The work reported here characterizes how students see the world through a filter of their own understanding. It explores how individual and social mechanisms in instruction support students as they expand the range of ideas under consideration and distinguish between these ideas using scientific criteria. Instruction supported students as they engaged in argumentation and debate on a set of multimedia evidence items from the World-Wide-Web. An argument editor called SenseMaker was designed and studied with the intent of making individual and group thinking visible during instruction. Over multiple classroom trials, different student cohorts were increasingly supported in scientific argumentation involving systematic coordination of evidence with theoretical ideas about light. Students' knowledge representations were used as mediating "learning artifacts" during classroom debate. Two argumentation conditions were investigated. The Full Scope group prepared to defend either theoretical position in the debate. These students created arguments that included more theoretical conjectures and made more conceptual progress in understanding light. The Personal Scope group prepared to defend their original opinion about the debate. These students produced more acausal descriptions of evidence and theorized less in their arguments. Regardless of students' prior knowledge of light, the Full Scope condition resulted in a more integrated understanding. Results from the research were synthesized in design principles geared towards helping future designers. Sharing and refining cognitive design principles offers a productive focus for developing a design science for education.

Kreutz, K. J.; Koffman, B. G.; Trenbath, K. L.

2013-12-01

What makes a good scientific argument? We began ERS201: Global Environmental Change by asking students to reflect on the mechanics of a strong scientific argument. At the same time, we asked them to evaluate global CO2 and sea level data from different time periods in Earth's history to answer the question, 'Is there a relationship between atmospheric CO2 and sea level, and if so, why?' This question formed the theme for the course, a mid-level, inquiry-based class of about 20 students. Each week, students target specific aspects of the climate system through problem sets, which include experimental and laboratory work, basic statistical analyses of paleoclimate datasets, and the development of simple systems models using STELLA software. Every 2-4 weeks, we challenge students to write short (1500 word) data-driven scientific arguments, which require a synthesis of information from their problem sets and from the scientific literature. Students have to develop a clear, testable hypothesis related to each writing prompt, and then make their case using figures they have generated during the weekly problem sets. We evaluate student writing using a rubric that focuses on the structure and clarity of the argument, relevance of the data included, and integration and quality of the graphics, with a lesser emphasis placed on voice and style. In 2013, student scores improved from a median value of 86 × 9% to 94 × 8% over the course of the semester. More importantly, we found that incorporation of scientific argumentation served to increase student understanding of important and sometimes abstract scientific concepts. For example, on pre- and post-course assessments we asked the question, 'What would happen if a significant portion of the sea ice floating in the Arctic Ocean were to melt?' On the pre-assessment, 80% of students said that it would lead to more coastal flooding, while only 20% correctly stated that a decrease in the reflection of solar energy would lead to warmer average global temperatures. On the post-assessment, nearly half of the respondents who originally had selected the sea level answer had switched to the correct response. Student understanding of climate-related concepts improved even if we did not explicitly teach a given subject. Thus, our approach challenged students to go beyond analyzing and interpreting data, to the point where they could articulate an argument based on a range of evidence. Students appreciated the challenge: in anonymous course evaluations, six out of fifteen students reported that scientific writing was the most valuable aspect of the course. Overall, we found that incorporating scientific argumentation improved student learning in this course. Here we will present relevant course content, exercises, assessment data, and student feedback to evaluate progress towards our goal of using a written argumentation approach to improving critical thinking, data analysis, and writing skills. We also discuss plans to incorporate peer review into the Spring 2014 course writing curriculum.

Teaching argumentation and scientific discourse using the ribosomal peptidyl transferase reaction.

Johnson, R Jeremy

2011-01-01

Argumentation and discourse are two integral parts of scientific investigation that are often overlooked in undergraduate science education. To address this limitation, the story of peptide bond formation by the ribosome can be used to illustrate the importance of evidence, claims, arguments, and counterarguments in scientific discourse. With the determination of the first structure of the large ribosomal subunit bound to a transition state inhibitor came an initial hypothesis about the role of the ribosome in peptide bond formation. This initial hypothesis was based on a few central assumptions about the transition state mimic and acid-base catalysis by serine proteases. The initial proposed mechanism started a flurry of scientific discourse in experimental articles and commentaries that tested the validity of the initial proposed mechanism. Using this civil argumentation as a guide, class discussions, assignments, and a debate were designed that allow students to analyze and question the claims and evidence about the mechanism of peptide bond synthesis. In the end, students develop a sense of critical skepticism, and an understanding of scientific discourse, while learning about the current consensus mechanism for peptide bond synthesis.

Argumentation is one factor that can help improve critical thinking skills. Arguing means to defend statements with the various data, denials, evidence, and reinforcement that support the statement. The research aimed to capture the quality of argument skills by students in grade 12 high school students and in postgraduate student on social-scientific issues of cancer. Both group subjects are not in the same school or institution, chosen purposively with the subject of 39 high school students of grade 12 in one district of West Java and 13 students of Biology education postgraduate in one of University in West Java - Indonesia. The results of the quality structure of arguments in both subject groups show the same pattern, which is claim - warrant - and ground, with the quality of counterclaim aspects on the postgraduate students look better than grade 12 students. This provides an illustration that the ability in argumentation between students and teachers in the socio-scientific issue of cancer should be evaluate so that the learning process would be more refined in schools.

The effects of a socioscientific issues instructional model in secondary agricultural education on students' content knowledge, scientific reasoning ability, argumentation skills, and views of the nature of science

NASA Astrophysics Data System (ADS)

Shoulders, Catherine Woglom

The purpose of this study was to determine the effects of a socioscientific issues-based instructional model on secondary agricultural education students' content knowledge, scientific reasoning ability, argumentation skills, and views of the nature of science. This study utilized a pre-experimental, single group pretest-posttest design to assess the impacts of a nine-week unit that incorporated a socioscientific issue into instruction on secondary agriculture students' agriscience content knowledge, scientific reasoning ability, argumentation skills, and views of the nature of science. The population for this study was Florida's secondary students enrolled in agricultural education. The accessible population was students enrolled in Agriscience Foundations classes in Florida. A convenience sample of Florida's Agriscience Foundations teachers attending a summer professional development or Chapter Officer Leadership Training session was taken. Paired-samples t tests were conducted to determine the impact the treatment had on students' agriscience content knowledge on distal and proximal assessments, as well as on students' scientific reasoning ability, argumentation skills related to number of argumentation justifications and quality of those justifications, and views of the nature of science. Paired-samples t tests were also conducted to determine whether the treatment yielded results with middle school or high school students. Statistical analysis found significant improvements in students' agriscience content knowledge, scientific reasoning ability, and argumentation skills. High school students' scores resulted in significant improvements in proximal content knowledge assessments and argumentation justification quality. Middle school students' scores resulted in significant improvements in proximal content knowledge assessments and scientific reasoning ability. No significant difference was found between students' views of the nature of science before and after the treatment. These findings indicate that socioscientific issues-based instruction can provide benefits for students in agricultural education. Teacher educators should work with teachers to maximize the learning that can occur through the various aspects of socioscientific issues-based instruction. Curriculum focusing on socioscientific issues-based instruction should be developed for specific courses in agricultural education. Finally, further investigation should be conducted to better understand how the aspects of socioscientific issues-based instruction can be altered to further enhance student learning.

Understanding ill-structured engineering ethics problems through a collaborative learning and argument visualization approach.

PubMed

Hoffmann, Michael; Borenstein, Jason

2014-03-01

As a committee of the National Academy of Engineering recognized, ethics education should foster the ability of students to analyze complex decision situations and ill-structured problems. Building on the NAE's insights, we report about an innovative teaching approach that has two main features: first, it places the emphasis on deliberation and on self-directed, problem-based learning in small groups of students; and second, it focuses on understanding ill-structured problems. The first innovation is motivated by an abundance of scholarly research that supports the value of deliberative learning practices. The second results from a critique of the traditional case-study approach in engineering ethics. A key problem with standard cases is that they are usually described in such a fashion that renders the ethical problem as being too obvious and simplistic. The practitioner, by contrast, may face problems that are ill-structured. In the collaborative learning environment described here, groups of students use interactive and web-based argument visualization software called "AGORA-net: Participate - Deliberate!". The function of the software is to structure communication and problem solving in small groups. Students are confronted with the task of identifying possible stakeholder positions and reconstructing their legitimacy by constructing justifications for these positions in the form of graphically represented argument maps. The argument maps are then presented in class so that these stakeholder positions and their respective justifications become visible and can be brought into a reasoned dialogue. Argument mapping provides an opportunity for students to collaborate in teams and to develop critical thinking and argumentation skills.

Chen, Ying-Chih; Hand, Brian; Park, Soonhye

2016-05-01

Argumentation, and the production of scientific arguments are critical elements of inquiry that are necessary for helping students become scientifically literate through engaging them in constructing and critiquing ideas. This case study employed a mixed methods research design to examine the development in 5th grade students' practices of oral and written argumentation from one unit to another over 16 weeks utilizing the science writing heuristic approach. Data sources included five rounds of whole-class discussion focused on group presentations of arguments that occurred over eleven class periods; students' group writings; interviews with six target students and the teacher; and the researcher's field notes. The results revealed five salient trends in students' development of oral and written argumentative practices over time: (1) Students came to use more critique components as they participated in more rounds of whole-class discussion focused on group presentations of arguments; (2) by challenging each other's arguments, students came to focus on the coherence of the argument and the quality of evidence; (3) students came to use evidence to defend, support, and reject arguments; (4) the quality of students' writing continuously improved over time; and (5) students connected oral argument skills to written argument skills as they had opportunities to revise their writing after debating and developed awareness of the usefulness of critique from peers. Given the development in oral argumentative practices and the quality of written arguments over time, this study indicates that students' development of oral and written argumentative practices is positively related to each other. This study suggests that argumentative practices should be framed through both a social and epistemic understanding of argument-utilizing talk and writing as vehicles to create norms of these complex practices.

The effect of scaffolded strategies on content learning in a designed science cyberlearning environment

NASA Astrophysics Data System (ADS)

Kern, Cynthia Lee

Scientific inscriptions---graphs, diagrams, and data---and argumentation are integral to generating and communicating scientific understanding. Scientific inscriptions and argumentation are also important to learning science. However, previous research has indicated that learners struggle to understand and learn science content represented in inscriptions. Furthermore, when learners engage in argumentation, learning science content becomes secondary to the learning of argumentation skills. This design-based research study is nested within the larger effort to inform the design and development of the 5-Featured Dynamic Inquiry Enterprise design framework (5-DIE) for cyberlearning environments and to advance theory associated with the difficulties learners have with scientific inscriptions and the consequences related to using argumentation to learn science content. In an attempt to engage participants in the process of learning science content with scientific inscriptions and argumentation, two learning strategies were embedded in a 5-DIE lessons. The two learning strategies evaluated in this study were (1) self-explanation prompts paired with a scientific inscription and (2) faded worked examples for the evaluation and development of scientific knowledge claims. The participants consisted of ninth and tenth grade students (age: 13-16 years; N=245) enrolled in one of three state-mandated biology courses taught by four different teachers. A three factor mixed model analysis of variance (ANOVA) with two between factors (self-explanation prompts and faded worked examples) and one within factor (pre, post, delayed post-test) was used to evaluate the effects of the learning strategies on the acquisition and retention of domain-specific content knowledge. Both between factors had two levels (with & without) and are described by the following experimental conditions: (1) control condition (general prompts), (2) self-explanation condition, (3) faded worked examples condition, and (4) combined condition with both self-explanation and faded worked examples. Acquisition and retention of content knowledge was assessed with a 17-item multiple-choice, researcher-developed content knowledge test. Results indicated that self-explanation prompts and faded worked examples learning strategies did not influence acquisition and retention of science content in a positive (i.e., learning) way. Based on the finding of this study, it may be concluded that the use of general prompts is as effective as self-explanation prompts and faded worked examples for scaffolding learner engagement with scientific inscriptions and argumentation. Furthermore, the finding indicated additional research is warranted evaluating the generalizability of scaffolds from college to pre-college populations.

2016-03-01

Scientific literacy, marked by the ability and willingness to engage with scientific information, is supported through a new genre of citizen science-course-based research in association with undergraduate laboratories. A three-phased progressive learning module was developed to enhance student engagement in such contexts while supporting three learning outcomes: I) present an argument based on evidence, II) analyze science and scientists within a social context, and III) experience, reflect upon, and communicate the nature of scientific discovery. Phase I entails guided reading and reflection of citizen science-themed texts. In Phase II, students write, peer-review, and edit position and counterpoint papers inspired by the following prompt, "Nonscientists should do scientific research." Phase III involves two creative assignments intended to communicate the true nature of science. Students work collaboratively to develop public service announcement-like poster campaigns to debunk a common misconception about the nature of science or scientists. Individually, they create a work of art to communicate a specific message about the raw experience of performing scientific research. Suggestions for implementation and modifications are provided. Strengths of the module include the development of transferable skills, temporal distribution of grading demands, minimal in-class time needed for implementation, and the inclusion of artistic projects to support affective learning domains. This citizen science-themed learning module is an excellent complement to laboratory coursework, as it serves to surprise, challenge, and inspire students while promoting disciplinary values.

Using the SEE-SEP Model to Analyze Upper Secondary Students' Use of Supporting Reasons in Arguing Socioscientific Issues

Christenson, Nina; Chang Rundgren, Shu-Nu; Höglund, Hans-Olof

2012-06-01

To achieve the goal of scientific literacy, the skills of argumentation have been emphasized in science education during the past decades. But the extent to which students can apply scientific knowledge to their argumentation is still unclear. The purpose of this study was to analyse 80 Swedish upper secondary students' informal argumentation on four socioscientific issues (SSIs) to explore students' use of supporting reasons and to what extent students used scientific knowledge in their arguments. Eighty upper secondary students were asked to express their opinions on one SSI topic they chose through written reports. The four SSIs in this study include global warming, genetically modified organisms (GMO), nuclear power, and consumption. To analyse students' supporting reasons from a holistic view, we used the SEE-SEP model, which links the six subject areas of sociology/culture (So), environment (En), economy (Ec), science (Sc), ethics/morality (Et) and policy (Po) connecting with three aspects, knowledge, value and personal experience (KVP). The results showed that students used value to a greater extent (67%) than they did scientific knowledge (27%) for all four SSI topics. According to the SEE-SEP model, the distribution of supporting reasons generated by students differed among the SSI topics. Also, some alternative concepts were disclosed in students' arguments. The implications for research and education are discussed.

Evidence and argument in policymaking: development of workplace smoking legislation

Apollonio, Dorie E; Bero, Lisa A

2009-01-01

Background We sought to identify factors that affect the passage of public health legislation by examining the use of arguments, particularly arguments presenting research evidence, in legislative debates regarding workplace smoking restrictions. Methods We conducted a case-study based content analysis of legislative materials used in the development of six state workplace smoking laws, including written and spoken testimony and the text of proposed and passed bills and amendments. We coded testimony given before legislators for arguments used, and identified the institutional affiliations of presenters and their position on the legislation. We compared patterns in the arguments made in testimony to the relative strength of each state's final legislation. Results Greater discussion of scientific evidence within testimony given was associated with the passage of workplace smoking legislation that provided greater protection for public health, regardless of whether supporters outnumbered opponents or vice versa. Conclusion Our findings suggest that an emphasis on scientific discourse, relative to other arguments made in legislative testimony, might help produce political outcomes that favor public health.

Argumentation as a Strategy for Conceptual Learning of Dynamics

NASA Astrophysics Data System (ADS)

Eskin, Handan; Ogan-Bekiroglu, Feral

2013-10-01

Researchers have emphasized the importance of promoting argumentation in science classrooms for various reasons. However, the study of argumentation is still a young field and more research needs to be carried out on the tools and pedagogical strategies that can assist teachers and students in both the construction and evaluation of scientific arguments. Thus, the aim of this study was to evaluate the impact of argumentation on students' conceptual learning in dynamics. True-experimental design using quantitative research methods was carried out for the study. The participants of the study were tenth graders studying in two classes in an urban all-girls school. There were 26 female students in each class. Five argumentations promoted in the different contexts were embedded through the dynamics unit over a 10-week duration. The study concludes that engaging in the argumentative process that involves making claims, using data to support these claims, warranting the claims with scientific evidence, and using backings, rebuttals, and qualifiers to further support the reasoning, reinforces students' understanding of science, and promotes conceptual change. The results suggest that argumentation should be employed during instruction as a way to enable conceptual learning.

Arguing from Nature: The role of `nature' in students' argumentations on a socio-scientific issue

NASA Astrophysics Data System (ADS)

Nielsen, Jan Alexis

2012-03-01

This paper explores how students invoked different conceptions of 'nature' in eight socio-scientific group discussions about human gene therapy. The paper illustrates and discusses how the students articulated nature and to what extent they elicited science factual content in the process. While the students in this study invoked nature at key places in a variety of dialectical contexts in the discussions, these invocations were often uncritical appeals and rarely involved science factual content. Even when an argument from nature was challenged, the author of that argument would often shift the sense of nature rather than elaborate upon the argumentation. It is argued that if students were properly introduced to the evaluative character of the term 'nature' it would not just be conducive to the quality of their argumentation, but also invite them to foreground science factual content at key places in their discussion.

Knowledge producers or knowledge consumers? Argumentation and decision making about environmental management

NASA Astrophysics Data System (ADS)

JiméNez-Aleixandre, Maria-Pilar

2002-11-01

This paper describes a case study involving decision making and argumentation, in the context of wetland environmental management, by 11th-grade students (16-17 years old). The purpose was to study the components of knowledge and skills needed to reach a decision in socio-scientific contexts and to identify them in classroom discourse. The following dimensions of decision making were explored: the use of relevant knowledge to understand and make decisions about the problem; and the critical processing of sources of information and authority and the development of criteria for evaluating possible solutions to the problem. Students' conversations were recorded and analysed using Toulmin's (1958) and Walton's (1996) argument schemes. The students' arguments and warrants were compared with the argument of an external 'official' expert. Issues such as expert status, that is, who can be considered as a source of knowledge and authority and the participation of citizens in scientific practice are also discussed.

Students' understandings of nature of science and their arguments in the context of four socio-scientific issues

NASA Astrophysics Data System (ADS)

Khishfe, Rola; Alshaya, Fahad S.; BouJaoude, Saouma; Mansour, Nasser; Alrudiyan, Khalid I.

2017-02-01

The purpose of this study was to examine students understandings about nature of science (NOS) and their arguments in context of controversial socio-scientific issue (SSI). A total of 74 11th graders in six schools in Saudi Arabia participated in the study. The instrument used was a questionnaire consisting of four scenarios addressing SSI about global warming, genetically modified food, acid rain, and human cloning. The scenarios were followed by questions relating to argumentation and NOS. Quantitative and qualitative measures were employed to analyze the data related to participants understandings of three NOS aspects (subjective, tentative, and empirical) and their arguments components (argument, counterargument, and rebuttal). Results showed no significant correlations between argument components and the NOS aspects. On the other hand, qualitative data showed that participants who generated well-developed arguments across the four SSI also exhibited more informed understandings of the NOS aspects, especially for female participants. Further, the chi-square analyses did not show significant differences in participants arguments and NOS understandings across the four scenarios. Again, the qualitative data from questionnaires showed differences in participants responses to the different scenarios. The results were interpreted along contextual factors, emotional factors, and cultural factors. Implications for the teaching of NOS and arguments were discussed.

2012-08-01

In the era of growing concerns about human-induced climate change and sustainable development, it is important for the schools to prepare students for meaningful engagement with environmental policies that will determine the future of our society. To do this, educators need to face a number of challenges. These include deciding on the science knowledge and skills needed for informed citizenship, identifying teaching practices for fostering such knowledge and skills, and finding ways to implement new practices into the tightly packed existing curriculum. This paper describes two collaborative efforts between the U.S. National Library of Medicine (NLM) and University of Maryland College of Education that attempt to meet these challenges. The focus of both projects is on helping students develop information seeking and evaluation and argumentation skills, and applying them to complex socio-scientific issues that have bearing on students' daily lives. The first effort involves co-designing an afterschool environmental health club curriculum with an interdisciplinary team of middle school teachers. The second effort is the development and implementation of a week-long school drinking water quality debate activity in a high school environmental science classroom. Both projects center on Tox Town, an NLM web resource that introduces students to environmental health issues in everyday environments. The paper describes successes and challenges of environmental health curriculum development, including teachers' and researchers' perception of contextual constraints in the club and classroom setting, tensions inherent in co-design, and students' experience with socio-scientific argumentation.

Space agencies' scientific roadmaps need harmonisation and reegular re-assessment

NASA Astrophysics Data System (ADS)

Worms, Jean-Claude; Culhane, J. Leonard; Walter, Nicolas; Swings, Jean-Pierre; Detsis, Emmanouil

The need to consider international collaboration in the exploration of space has been recognised since the dawn of the space age in 1957. Since then, international collaboration has been the main operational working mode amongst space scientists the world over, setting aside national pre-eminence and other political arguments. COSPAR itself was created as a tool for scientists to maintain the dialogue at the time of the cold war. Similarly the inherent constraints of the field (cost, complexity, time span) have led space agencies to try and coordinate their efforts. As a result many - if not all - of the key space science missions since the 60’s have been collaborative by nature. Different collaboration models have existed with varying success, and the corresponding lessons learned have been assessed through various fora and reports. For various reasons whose scope has broadened since that time (use of space in other domains such as Earth observation, telecommunication and navigation; emergence of commercial space activities; increased public appeal and capacity to motivate the young generation to engage into related careers), the importance of international collaboration in space has never faltered and coordination among spacefaring nations has become the norm. However programme harmonisation is often found to be lacking, and duplication of efforts sometimes happens due to different planning and decision procedures, programmatic timelines or budgetary constraints. Previous studies, in particular by the European ESSC-ESF, with input from the US NAS-SSB, advocated the need to establish a coordinating body involving major space agencies to address these coordination issues in a systematic and harmonious way. Since then and in line with this recommendation, the International Space Exploration Coordination Group (ISECG) of 14 space agencies was created in 2007 and published a first roadmap to advance a “Global Exploration Strategy”. ISECG is non-binding though and recent examples of lack of coordination in international planning probably indicate that this should be brought to a higher, more systematic level of coordination. Even more recently, discussions i.e. at the ISECG level, have led this forum to envisage setting up a Science Working Group to inform ISECG on ways to better coordinate the “…interaction between the exploration community…” (i.e. agencies) and the “…scientific community”. Following the recommendations by ESSC-ESF, the need for a rational and systematic approach to the harmonisation of agencies’ scientific roadmaps should be undertaken on a regular basis (ideally on an annual basis), through an inter-agency scientific collaboration working group, which would include agency executives but also scientific membership chosen after appropriate consultation. The ISECG Science Working Group could serve as an embryo to this inter-agency body. The presentation will offer prospects for the establishment of such a body and suggestions on its operating mode.

Contemporary HIV/AIDS research: Insights from knowledge management theory

PubMed Central

Callaghan, Chris William

2017-01-01

Abstract Knowledge management as a field is concerned with the management of knowledge, including the management of knowledge in research processes. Knowledge management theory has the potential to support research into problems such as HIV, antibiotic resistance and others, particularly in terms of aspects of scientific research related to the contribution of social science. To date, however, these challenges remain with us, and theoretical contributions that can complement natural science efforts to eradicate these problems are needed. This paper seeks to offer a theoretical contribution grounded in Kuhn’s paradigm theory of innovation, and in the argument by Lakatos that scientific research can be fundamentally non-innovative, which suggests that social science aspects of knowledge creation may hold the key to more effective biomedical innovation. Given the consequences of ongoing and emerging global crises, and the failure of knowledge systems of scientific research to solve such problems outright, this paper provides a review of theory and literature arguing for a new paradigm in scientific research, based on the development of global systems to maximise research collaborations. A global systems approach effectively includes social science theory development as an important complement to the natural sciences research process. Arguably, information technology and social media technology have developed to the point at which solutions to knowledge aggregation challenges can enable solutions to knowledge problems on a scale hitherto unimaginable. Expert and non-expert crowdsourced inputs can enable problem-solving through exponentially increasing problem-solving inputs, using the ‘crowd,’ thereby increasing collaborations dramatically. It is argued that these developments herald a new era of participatory research, or a democratisation of research, which offers new hope for solving global social problems. This paper seeks to contribute to this end, and to the recognition of the important role of social theory in the scientific research process. PMID:28922967

Epistemological pluralism and scientific development: an argument against authoritative nosologies.

PubMed

Markon, Kristian E

2013-10-01

The author examines the influence of authoritative nosological systems--those developed by an authoritative body or organization (e.g., the DSM, ICD, RDoC)--on the development of scientific theory and research. Although there has been extensive discussion of how such systems should be organized, and of the historical role of such systems, little focus has been placed on whether these systems impede or facilitate scientific progress. The author reviews the nature and role of constructs in scientific theory and the role of authoritative taxonomy in science. He presents an argument that, although authoritative classification systems clearly have value for nonscientific purposes, or for specific scientific purposes, the systems themselves, at least as they have been constructed thus far, likely impede scientific development by constraining competitive discourse. Implications and recommendations are discussed.

Global Learning Communities: A Comparison of Online Domestic and International Science Class Partnerships

Kerlin, Steven C.; Carlsen, William S.; Kelly, Gregory J.; Goehring, Elizabeth

2013-08-01

The conception of Global Learning Communities (GLCs) was researched to discover potential benefits of the use of online technologies that facilitated communication and scientific data sharing outside of the normal classroom setting. 1,419 students in 635 student groups began the instructional unit. Students represented the classrooms of 33 teachers from the USA, 6 from Thailand, 7 from Australia, and 4 from Germany. Data from an international environmental education project were analyzed to describe grades 7-9 student scientific writing in domestic US versus international-US classroom online partnerships. The development of an argument analytic and a research model of exploratory data analysis followed by statistical testing were used to discover and highlight different ways students used evidence to support their scientific claims about temperature variation at school sites and deep-sea hydrothermal vents. Findings show modest gains in the use of some evidentiary discourse components by US students in international online class partnerships compared to their US counterparts in domestic US partnerships. The analytic, research model, and online collaborative learning tools may be used in other large-scale studies and learning communities. Results provide insights about the benefits of using online technologies and promote the establishment of GLCs.

From interaction to interaction: Exploring shared resources constructed through and mediating classroom science learning

NASA Astrophysics Data System (ADS)

Tang, Xiaowei

Recent reform documents and science education literature emphasize the importance of scientific argumentation as a discourse and practice of science that should be supported in school science learning. Much of this literature focuses on the structure of argument, whether for assessing the quality of argument or designing instructional scaffolds. This study challenges the narrowness of this research paradigm and argues for the necessity of examining students' argumentative practices as rooted in the complex, evolving system of the classroom. Employing a sociocultural-historical lens of activity theory (Engestrom, 1987, 1999), discourse analysis is employed to explore how a high school biology class continuously builds affordances and constraints for argumentation practices through interactions. The ways in which argumentation occurs, including the nature of teacher and student participation, are influenced by learning goals, classroom norms, teacher-student relationships and epistemological stances constructed through a class' interactive history. Based on such findings, science education should consider promoting classroom scientific argumentation as a long-term process, requiring supportive resources that develop through continuous classroom interactions. Moreover, in order to understand affordances that support disciplinary learning in classroom, we need to look beyond just disciplinary interactions. This work has implications for classroom research on argumentation and teacher education, specifically, the preparation of teachers for secondary science teaching.

Enhancing the quality of argumentation in school science

Osborne, Jonathan; Erduran, Sibel; Simon, Shirley

2004-12-01

The research reported in this study focuses on the design and evaluation of learning environments that support the teaching and learning of argumentation in a scientific context. The research took place over 2 years, between 1999 and 2001, in junior high schools in the greater London area. The research was conducted in two phases. In phase 1, working with a group of 12 science teachers, the main emphasis was to develop sets of materials and strategies to support argumentation in the classroom, and to support and assess teachers' development with teaching argumentation. Data were collected by video- and audio-recording the teachers' attempts to implement these lessons at the beginning and end of the year. During this phase, analytical tools for evaluating the quality of argumentation were developed based on Toulmin's argument pattern. Analysis of the data shows that there was significant development in the majority of teachers use of argumentation across the year. Results indicate that the pattern of use of argumentation is teacher-specific, as is the nature of the change. In phase 2 of the project, the focus of this paper, teachers taught the experimental groups a minimum of nine lessons which involved socioscientific or scientific argumentation. In addition, these teachers taught similar lessons to a comparison group at the beginning and end of the year. The purpose of this research was to assess the progression in student capabilities with argumentation. For this purpose, data were collected from 33 lessons by video-taping two groups of four students in each class engaging in argumentation. Using a framework for evaluating the nature of the discourse and its quality developed from Toulmin's argument pattern, the findings show that there was improvement in the quality of students' argumentation. This research presents new methodological developments for work in this field.

Teacher argumentation in the secondary science classroom: Images of two modes of scientific inquiry

NASA Astrophysics Data System (ADS)

Gray, Ron E.

The purpose of this exploratory study was to examine scientific arguments constructed by secondary science teachers during instruction. The analysis focused on how arguments constructed by teachers differed based on the mode of inquiry underlying the topic. Specifically, how did the structure and content of arguments differ between experimentally and historically based topics? In addition, what factors mediate these differences? Four highly experienced high school science teachers were observed daily during instructional units for both experimental and historical science topics. Data sources include classroom observations, field notes, reflective memos, classroom artifacts, a nature of science survey, and teacher interviews. The arguments were analyzed for structure and content using Toulmin's argumentation pattern and Walton's schemes for presumptive reasoning revealing specific patterns of use between the two modes of inquiry. Interview data was analyzed to determine possible factors mediating these patterns. The results of this study reveal that highly experienced teachers present arguments to their students that, while simple in structure, reveal authentic images of science based on experimental and historical modes of inquiry. Structural analysis of the data revealed a common trend toward a greater amount of scientific data used to evidence knowledge claims in the historical science units. The presumptive reasoning analysis revealed that, while some presumptive reasoning schemes remained stable across the two units (e.g. 'causal inferences' and 'sign' schemes), others revealed different patterns of use including the 'analogy', 'evidence to hypothesis', 'example', and 'expert opinion' schemes. Finally, examination of the interview and survey data revealed five specific factors mediating the arguments constructed by the teachers: view of the nature of science, nature of the topic, teacher personal factors, view of students, and pedagogical decisions. These factors influenced both the structure and use of presumptive reasoning in the arguments. The results have implications for classroom practice, teacher education, and further research.

Student use of Web 2.0 tools to support argumentation in a high school science classroom

NASA Astrophysics Data System (ADS)

Weible, Jennifer L.

This ethnographic study is an investigation into how two classes of chemistry students (n=35) from a low-income high school with a one-to-one laptop initiative used Web 2.0 tools to support participation in the science practice of argumentation (i.e., sensemaking, articulating understandings, and persuading an audience) during a unit on alternative energy. The science curriculum utilized the Technology-Enhanced Inquiry Tools for Science Education as a pedagogical framework (Kim, Hannafin, & Bryan, 2007). Video recordings of the classroom work, small group discussions, and focus group interviews, documents, screen shots, wiki evidence, and student produced multi-media artifacts were the data analyzed for this study. Open and focused coding techniques, counts of social tags and wiki moves, and interpretive analyses were used to find patterns in the data. The study found that the tools of social bookmarking, wiki, and persuasive multimedia artifacts supported participation in argumentation. In addition, students utilized the affordances of the technologies in multiple ways to communicate, collaborate, manage the work of others, and efficiently complete their science project. This study also found that technologically enhanced science curriculum can bridge students' everyday and scientific understandings of making meaning, articulating understandings, and persuading others of their point of view. As a result, implications from this work include a set of design principles for science inquiry learning that utilize technology. This study suggests new consideration of analytical methodology that blends wiki data analytics and video data. It also suggests that utilizing technology as a bridging strategy serves two roles within classrooms: (a) deepening students' understanding of alternative energy science content and (b) supporting students as they learn to participate in the practices of argumentation.

A three-phased progressive learning module was developed to enhance student engagement in such contexts while supporting three learning outcomes: I) present an argument based on evidence, II) analyze science and scientists within a social context, and III) experience, reflect upon, and communicate the nature of scientific discovery. Phase I entails guided reading and reflection of citizen science–themed texts. In Phase II, students write, peer-review, and edit position and counterpoint papers inspired by the following prompt, “Nonscientists should do scientific research.” Phase III involves two creative assignments intended to communicate the true nature of science. Students work collaboratively to develop public service announcement–like poster campaigns to debunk a common misconception about the nature of science or scientists. Individually, they create a work of art to communicate a specific message about the raw experience of performing scientific research. Suggestions for implementation and modifications are provided. Strengths of the module include the development of transferable skills, temporal distribution of grading demands, minimal in-class time needed for implementation, and the inclusion of artistic projects to support affective learning domains. This citizen science–themed learning module is an excellent complement to laboratory coursework, as it serves to surprise, challenge, and inspire students while promoting disciplinary values.

How People Reason: A Grounded Theory Study of Scientific Reasoning about Global Climate Change

NASA Astrophysics Data System (ADS)

Liu, Shiyu

Scientific reasoning is crucial in both scientific inquiry and everyday life. While the majority of researchers have studied "how people reason" by focusing on their cognitive processes, factors related to the underpinnings of scientific reasoning are still under-researched. The present study aimed to develop a grounded theory that captures not only the cognitive processes during reasoning but also their underpinnings. In particular, the grounded theory and phenomenographic methodologies were integrated to explore how undergraduate students reason about competing theories and evidence on global climate change. Twenty-six undergraduate students were recruited through theoretical sampling. Constant comparative analysis of responses from interviews and written assessments revealed that participants were mostly drawn to the surface features when reasoning about evidence. While prior knowledge might not directly contribute to participants' performance on evidence evaluation, it affected their level of engagement when reading and evaluating competing arguments on climate issues. More importantly, even though all participants acknowledged the relative correctness of multiple perspectives, they predominantly favored arguments that supported their own beliefs with weak scientific reasoning about the opposing arguments. Additionally, factors such as personal interests, religious beliefs, and reading capacity were also found to have bearings on the way participants evaluated evidence and arguments. In all, this work contributes to the current endeavors in exploring the nature of scientific reasoning. Taking a holistic perspective, it provides an in-depth discussion of factors that may affect or relate to scientific reasoning processes. Furthermore, in comparison with traditional methods used in the literature, the methodological approach employed in this work brought an innovative insight into the investigation of scientific reasoning. Last but not least, this research may help initiate further discussion regarding how to bridge cognitive research with science education to promote student learning of complex scientific issues such as global climate change.

The Nature of the Arguments for Creationism, Intelligent Design, and Evolution

NASA Astrophysics Data System (ADS)

Barnes, Ralph M.; Church, Rebecca A.; Draznin-Nagy, Samuel

2017-03-01

Seventy-two Internet documents promoting creationism, intelligent design (I.D.), or evolution were selected for analysis. The primary goal of each of the 72 documents was to present arguments for creationism, I.D., or evolution. We first identified all arguments in these documents. Each argument was then coded in terms of both argument type (appeal to authority, appeal to empirical evidence, appeal to reason, etc.) and argument topic (age of earth, mechanism of descent with modification, etc.). We then provided a quantitative summary of each argument type and topic for each of the three positions. Three clear patterns were revealed by the data. First, websites promoting evolution were characterized by a narrow focus on appeals to empirical evidence, whereas websites promoting creationism and I.D. were quite heterogeneous in regards to argument type. Second, websites promoting evolution relied primarily on a small number of empirical examples (e.g., fossils, biogeography, homology, etc.), while websites promoting creationism and I.D. used a far greater range of arguments. Finally, websites promoting evolution were narrowly focused on the topic of descent with modification. In contrast, websites promoting creationism tackled a broad range of topics, while websites promoting I.D. were narrowly focused on the issue of the existence of God. The current study provides a quantitative summary of a systematic content analysis of argument type and topic across a large number of frequently accessed websites dealing with origins. The analysis we have used may prove fruitful in identifying and understanding argumentation trends in scientific writing and pseudo-scientific writing.

Is Lifecycle Analysis Unconstitutional? New Frontiers in the Legal Battle Over Climate Science

NASA Astrophysics Data System (ADS)

Cullenward, D.; Weiskopf, D.

2012-12-01

Recent federal court decisions have established that judges should not second-guess government agency findings related to basic climate change science [1,2]. Nevertheless, the legal battle over climate science is far from over. In the absence of federal legislation, climate policy opponents are developing new arguments to challenge the authority of states to regulate greenhouse gas emissions. This presentation describes a recent challenge to California's climate policy and provides an example of a strategic scientific response. In December 2011, a federal district court ruled that California's Low Carbon Fuel Standard ("LCFS") is unconstitutional [3]. The LCFS regulations employ lifecycle analysis to set a limit on the carbon intensity of fuels sold in California. According to the court, however, the policy's use of lifecycle analysis "facially discriminates" against interstate commerce. Because the court found that nondiscriminatory alternatives were available, it held the policy unconstitutional. If upheld, this reasoning would severely limit the ability of states to address climate change. On appeal to the Ninth Circuit, the Stanford Environmental Law Clinic represented climate scientists [4] and lifecycle analysis scientists [5] in support of upholding the LCFS. These briefs addressed the necessity of lifecycle analysis in the context of transportation fuels, and also presented evidence from the climate impacts literature that supports the state's interest in pursuing climate policy. Although written for the court and targeted at specific legal questions, both briefs were developed in the style of scientific assessments, based on published literature [6,7] and feedback from reviewers. Because courts lack the expertise to evaluate arguments about scientific issues, there is an ongoing need for climate scientists to participate in litigation. Perhaps most importantly, an effective response requires interdisciplinary collaboration between lawyers and scientists. Briefs must be framed to persuade judges and address specific legal questions, but must also accurately reflect the state of scientific evidence, including an accurate depiction of scientific uncertainty. Using the Clinic's experience in the LCFS case as an example, we reflect on opportunities for the scientific and legal communities to strategically collaborate in the future.

Individual to collaborative: guided group work and the role of teachers in junior secondary science classrooms

NASA Astrophysics Data System (ADS)

Fung, Dennis; Lui, Wai-mei

2016-05-01

This paper, through discussion of a teaching intervention at two secondary schools in Hong Kong, demonstrates the learning advancement brought about by group work and dissects the facilitating role of teachers in collaborative discussions. One-hundred and fifty-two Secondary Two (Grade 8) students were divided into three pedagogical groups, namely 'whole-class teaching', 'self-directed group work' and 'teacher-supported group work' groups, and engaged in peer-review, team debate, group presentation and reflection tasks related to a junior secondary science topic (i.e. current electricity). Pre- and post-tests were performed to evaluate students' scientific conceptions, alongside collected written responses and audio-recorded discussions. The results indicate that students achieved greater cognitive growth when they engaged in cooperative learning activities, the interactive and multi-sided argumentative nature of which is considered to apply particularly well to science education and Vygotsky's zone of proximal development framework. Group work learning is also found to be most effective when teachers play a role in navigating students during the joint construction of conceptual knowledge.

Socioscientific Issues: A Path Towards Advanced Scientific Literacy and Improved Conceptual Understanding of Socially Controversial Scientific Theories

NASA Astrophysics Data System (ADS)

Pinzino, Dean William

This thesis investigates the use of socioscientific issues (SSI) in the high school science classroom as an introduction to argumentation and socioscientific reasoning, with the goal of improving students' scientific literacy (SL). Current research is reviewed that supports the likelihood of students developing a greater conceptual understanding of scientific theories as well as a deeper understanding of the nature of science (NOS), through participation in informal and formal forms of argumentation in the context of SSI. Significant gains in such understanding may improve a student's ability to recognize the rigor, legitimacy, and veracity of scientific claims and better discern science from pseudoscience. Furthermore, students that participate in significant SSI instruction by negotiating a range of science-related social issues can make significant gains in content knowledge and develop the life-long skills of argumentation and evidence-based reasoning, goals not possible in traditional lecture-based science instruction. SSI-based instruction may therefore help students become responsible citizens. This synthesis also suggests that that the improvements in science literacy and NOS understanding that develop from sustained engagement in SSI-based instruction will better prepare students to examine and scrutinize socially controversial scientific theories (i.e., evolution, global warming, and the Big Bang).

Small-group, computer-mediated argumentation in middle-school classrooms: the effects of gender and different types of online teacher guidance.

Asterhan, Christa S C; Schwarz, Baruch B; Gil, Julia

2012-09-01

Research has shown the importance of careful teacher support during collaborative group work to promote productive discourse between students (Webb, 2009). However, this research has traditionally focused on face-to-face communication. The role of online teacher guidance of small-group computer-mediated discussions has received little attention, especially in secondary school classroom settings. Researchers of computer-supported collaborative learning (CSCL), on the other hand, have traditionally focused on software-embedded features, such as scripts, to support a-synchronous peer dialogue, and less so on human guidance of synchronous group discussions. The main aim of the present in vivo, experimental study is to examine whether online teacher guidance can improve the quality of small-group synchronous discussions, and whether different types of guidance (epistemic or interaction guidance) affect these discussions differently, when compared to an unguided condition. The second goal of this study is to explore potential differences between all-female and all-male discussion groups. Eighty-two 9th graders (three classrooms) and six teachers from a rural high school in Israel. Whereas epistemic guidance only improved aspects of the argumentative quality of the discussion, interaction guidance only improved aspects of collaboration. Discussions of all-girls groups scored higher on aspects of collaboration and argumentative quality, compared to all-boys groups. The findings show that teacher guidance of synchronous, online discussions in classrooms is realizable and reasonably reaches its intended goals. Training should be focused on acquiring various guidance strategies to augment their beneficial effects. Furthermore, future research should pay more attention to potential gender differences in peer-to-peer argumentation. ©2011 The British Psychological Society.

Design, science and naturalism

NASA Astrophysics Data System (ADS)

Deming, David

2008-09-01

The Design Argument is the proposition that the presence of order in the universe is evidence for the existence of God. The Argument dates at least to the presocratic Greek philosophers, and is largely based on analogical reasoning. Following the appearance of Aquinas' Summa Theologica in the 13th century, the Christian Church in Europe embraced a Natural Theology based on observation and reason that allowed it to dominate the entire world of knowledge. Science in turn advanced itself by demonstrating that it could be of service to theology, the recognized queen of the sciences. During the heyday of British Natural Theology in the 17th and 18th centuries, the watchmaker, shipbuilder, and architect analogies were invoked reflexively by philosophers, theologians, and scientists. The Design Argument was not systematically and analytically criticized until David Hume wrote Dialogues on Natural Religion in the 1750s. After Darwin published Origin of Species in 1859, Design withered on the vine. But in recent years, the Argument has been resurrected under the appellation "intelligent design," and been the subject of political and legal controversy in the United States. Design advocates have argued that intelligent design can be formulated as a scientific hypothesis, that new scientific discoveries validate a design inference, and that naturalism must be removed as a methodological requirement in science. If science is defined by a model of concentric epistemological zonation, design cannot be construed as a scientific hypothesis because it is inconsistent with the core aspects of scientific methodology: naturalism, uniformity, induction, and efficient causation. An analytical examination of claims by design advocates finds no evidence of any type to support either scientific or philosophical claims that design can be unambiguously inferred from nature. The apparent irreducible complexity of biological mechanisms may be explained by exaptation or scaffolding. The argument that design is indicated by the fine-tuning of the universe as a habitat suitable for life is based on an intellectual fallacy of assigning probability to a unique event. Construing the Design Argument as an "inference to the best explanation," rather than analogical reasoning is essentially an equivocation fallacy that does not rescue the Argument from Hume's criticisms. The intelligent design movement is a threat to the unity of science, as its confessed goal is to restore Christian theology as the queen of the sciences.

Implementation of a Curriculum-Integrated Computer Game for Introducing Scientific Argumentation

NASA Astrophysics Data System (ADS)

Wallon, Robert C.; Jasti, Chandana; Lauren, Hillary Z. G.; Hug, Barbara

2017-11-01

Argumentation has been emphasized in recent US science education reform efforts (NGSS Lead States 2013; NRC 2012), and while existing studies have investigated approaches to introducing and supporting argumentation (e.g., McNeill and Krajcik in Journal of Research in Science Teaching, 45(1), 53-78, 2008; Kang et al. in Science Education, 98(4), 674-704, 2014), few studies have investigated how game-based approaches may be used to introduce argumentation to students. In this paper, we report findings from a design-based study of a teacher's use of a computer game intended to introduce the claim, evidence, reasoning (CER) framework (McNeill and Krajcik 2012) for scientific argumentation. We studied the implementation of the game over two iterations of development in a high school biology teacher's classes. The results of this study include aspects of enactment of the activities and student argument scores. We found the teacher used the game in aspects of explicit instruction of argumentation during both iterations, although the ways in which the game was used differed. Also, students' scores in the second iteration were significantly higher than the first iteration. These findings support the notion that students can learn argumentation through a game, especially when used in conjunction with explicit instruction and support in student materials. These findings also highlight the importance of analyzing classroom implementation in studies of game-based learning.

2013-11-01

Purpose: The purpose of this study was to assess the quality of scientific arguments developed by pre-service physics teachers. Sample: The participants were 171 pre-service physics teachers recruited from two universities: 86 from University A and 85 from University B. Design and method: Participants were prompted to develop a written argument to either support or challenge the Turkish government's decision to invest in nuclear power plants. Data consist of written arguments developed by the participants and information on participants' knowledge of the topic, their confidence in their knowledge and the source of their knowledge related to the topic. Data were analyzed using the CER framework. Results: The results show that participants did not perform at the expected level. The majority of students failed to develop strong scientific arguments. While almost all of the participants provided evidence to justify their claims, they failed to effectively coordinate evidence, claim and theory to develop an argument. Students struggled the most in the warrant/reasoning category of the CER framework. We also identified several misconceptions that students held related to nuclear power plants. Conclusions: In our discussion we problematize college science teaching and advocate integration of instructional strategies such as argumentation that can effectively engage students in construction, evaluation and justification of knowledge.

The current developments in healthcare are unprecedented. The organization of health care is complex. Collaboration is essential to meet all the healthcare needs of patients and to achieve coordinated and unambiguous information.

However, collaboration and MPE are wrestling with the same problems: social identity and acceptance.

The dual-use problem, scientific isolationism and the division of moral labour.

PubMed

Douglas, Thomas

2014-01-01

The dual-use problem is an ethical quandary sometimes faced by scientists and others in a position to influence the creation or dissemination of scientific knowledge. It arises when (i) an agent is considering whether to pursue some project likely to result in the creation or dissemination of scientific knowledge, (ii) that knowledge could be used in both morally desirable and morally undesirable ways, and (iii) the risk of undesirable use is sufficiently high that it is not clear that the agent may permissibly pursue the project or policy. Agents said to be faced with dual-use problems have frequently responded by appealing to a view that I call scientific isolationism. This is, roughly, the view that scientific decisions may be made without morally appraising the likely uses of the scientific knowledge whose production or dissemination is at stake. I consider whether scientific isolationism can be justified in a form that would indeed provide a way out of dual-use problems. I first argue for a presumption against a strong form of isolationism, and then examine four arguments that might be thought to override this presumption. The most promising of these arguments appeals to the idea of a division of moral labour, but I argue that even this argument can sustain at most a highly attenuated form of scientific isolationism and that this variant of isolationism has little practical import for discussions of the dual-use problem.

The Effect of Scaffolding Strategies for Inscriptions and Argumentation in a Science Cyberlearning Environment

NASA Astrophysics Data System (ADS)

Kern, Cindy L.; Crippen, Kent J.

2017-02-01

Scientific inscriptions—graphs, diagrams, and data—and argumentation are integral to learning and communicating science and are common elements in cyberlearning environments—those involving the use of networked learning technologies. However, previous research has indicated that learners struggle to use inscriptions and when they engage in argumentation, the learning of science content becomes secondary to the learning of argumentation skills. The purpose of this study was to evaluate two scaffolding strategies for these elements in a secondary school context: (1) self- explanation prompts paired with a scientific inscription and (2) faded worked examples for the evaluation and development of scientific arguments. Participants consisted of ninth and tenth grade students (age 13-16 years; N = 245) enrolled in state-mandated biology courses taught by four different teachers. A three-factor mixed model analysis of variance with two between factors (self-explanation prompts and faded worked examples) and one within factor (pre-, post-, delayed posttest) was used to evaluate the effects on the acquisition and retention of domain-specific content knowledge. Results indicated that neither strategy influenced the acquisition and retention of science content in a positive (i.e., learning) or negative (i.e., expertise reversal effect) way. Thus, general prompts were as effective as either of the scaffolding conditions. These unanticipated results suggest that additional research is warranted for learning scaffolds with pre-college populations where the gains were established with college-aged participants.

Understanding a High School Physics Teacher's Pedagogical Content Knowledge of Argumentation

NASA Astrophysics Data System (ADS)

Wang, Jianlan; Buck, Gayle A.

2016-08-01

Scientific argumentation is an important learning objective in science education. It is also an effective instructional approach to constructivist science learning. The implementation of argumentation in school settings requires science teachers, who are pivotal agents of transforming classroom practices, to develop sophisticated knowledge of argumentation. However, there is a lack of understanding about science teachers' knowledge of argumentation, especially the dialogic meaning of argumentation. In this case study, we closely examine a high school physics teacher's argumentation-related pedagogic content knowledge (PCK) in the context of dialogic argumentation. We synthesize the teacher's performed PCK from his argumentation practices and narrated PCK from his reflection on the argumentation practices, from which we summarize his PCK of argumentation from the perspectives of orientation, instructional strategies, students, curriculum, and assessment. Finally, we describe the teacher's perception and adaption of argumentation in his class. We also identity the barriers to argumentation implementation in this particular case and suggest solutions to overcome these barriers.

Analyzing arguments in science classroom discourse: Can teachers' questions distort scientific authority?

NASA Astrophysics Data System (ADS)

Russell, Thomas L.

Teaching commonly involves asking questions, in sequences that enable a teacher to control the direction and duration of subject-matter discussion, while also maintaining attention and order. The form of questions and their role as means of instruction have received more study and discussion than the function of questions and their role in achieving particular ends of instruction. This study examines qualitatively the function of questions in developing arguments that establish scientific knowledge claims on the basis of reasons and evidence, and thereby suggest a rational attitude toward authority. Peters' (1966) distinction between a teacher's (rational) authority of knowledge and (traditional) authority of position is linked with Toulmin's (1958) pattern for rational arguments to establish a qualitative framework for judging the function of questions in arguments. Episodes from three science lessons are presented in verbatim transcription and analyzed to reveal three different ways in which teachers did not achieve the standard of suggesting a rational attitude toward authority. Question sequences such as these have a clear potential for distorting student understanding of the nature of scientific authority, with possible negative consequences for students' attitudes toward science.Received: 30 November 1981;

TAPping into argumentation: Developments in the application of Toulmin's Argument Pattern for studying science discourse

NASA Astrophysics Data System (ADS)

Erduran, Sibel; Simon, Shirley; Osborne, Jonathan

2004-11-01

This paper reports some methodological approaches to the analysis of argumentation discourse developed as part of the two-and-a-half year project titled Enhancing the Quality of Argument in School Scienc'' supported by the Economic and Social Research Council in the United Kingdom. In this project researchers collaborated with middle-school science teachers to develop models of instructional activities in an effort to make argumentation a component of instruction. We begin the paper with a brief theoretical justification for why we consider argumentation to be of significance to science education. We then contextualize the use of Toulmin's Argument Pattern in the study of argumentation discourse and provide a justification for the methodological outcomes our approach generates. We illustrate how our work refines and develops research methodologies in argumentation analysis. In particular, we present two methodological approaches to the analysis of argumentation resulting in whole-class as well as small-group student discussions. For each approach, we illustrate our coding scheme and some results as well as how our methodological approach has enabled our inquiry into the quality of argumentation in the classroom. We conclude with some implications for future research in argumentation in science education.

Science curriculum is often used as a means to train students as future scientists with less emphasis placed on preparing students to reason about issues they may encounter in their daily lives (Feinstein, Allen, & Jenkins, 2013; Roth & Barton, 2004). The general public is required to think scientifically to some degree throughout their life and often across a variety of issues. From an empirical standpoint, we do not have a robust understanding of what scientific knowledge the public finds useful for reasoning about socio-scientific issues in their everyday lives (Feinstein, 2011). We also know very little about how the situational features of an issue influences reasoning strategy (i.e., the use of knowledge to generate arguments). Rapid advances in science - particularly in genetics - increasingly challenge the public to reason about socio-scientific issues. This raises questions about the public's ability to participate knowledgeably in socio-scientific debates, and to provide informed consent for a variety of novel scientific procedures. This dissertation aims to answer the questions: How do individuals use their genetic content knowledge to reason about authentic issues they may encounter in their daily lives? Individuals' scientific knowledge is a critical aspect of scientific literacy, but what scientific literacy looks like in practice as individuals use their content knowledge to reason about issues comprised of different situational features is still unclear. The purpose of this dissertation is to explore what knowledge is actually used by individuals to generate and support arguments about a variety of socio-scientific issues, and how the features of those issues influences reasoning strategy. Three studies were conducted to answer questions reflecting this purpose. Findings from this dissertation provide important insights into what scientific literacy looks like in practice.

Earthquake: Game-based learning for 21st century STEM education

NASA Astrophysics Data System (ADS)

Perkins, Abigail Christine

To play is to learn. A lack of empirical research within game-based learning literature, however, has hindered educational stakeholders to make informed decisions about game-based learning for 21st century STEM education. In this study, I modified a research and development (R&D) process to create a collaborative-competitive educational board game illuminating elements of earthquake engineering. I oriented instruction- and game-design principles around 21st century science education to adapt the R&D process to develop the educational game, Earthquake. As part of the R&D, I evaluated Earthquake for empirical evidence to support the claim that game-play results in student gains in critical thinking, scientific argumentation, metacognitive abilities, and earthquake engineering content knowledge. I developed Earthquake with the aid of eight focus groups with varying levels of expertise in science education research, teaching, administration, and game-design. After developing a functional prototype, I pilot-tested Earthquake with teacher-participants (n=14) who engaged in semi-structured interviews after their game-play. I analyzed teacher interviews with constant comparison methodology. I used teachers' comments and feedback from content knowledge experts to integrate game modifications, implementing results to improve Earthquake. I added player roles, simplified phrasing on cards, and produced an introductory video. I then administered the modified Earthquake game to two groups of high school student-participants (n = 6), who played twice. To seek evidence documenting support for my knowledge claim, I analyzed videotapes of students' game-play using a game-based learning checklist. My assessment of learning gains revealed increases in all categories of students' performance: critical thinking, metacognition, scientific argumentation, and earthquake engineering content knowledge acquisition. Players in both student-groups improved mostly in critical thinking, having doubled the number of exhibited instances of critical thinking between games. Players in the first group exhibited about a third more instances of metacognition between games, while players in the second group doubled such instances. Between games, players in both groups more than doubled the number of exhibited instances of using earthquake engineering content knowledge. The student-players expanded use of scientific argumentation for all game-based learning checklist categories. With empirical evidence, I conclude play and learning can connect for successful 21 st century STEM education.

The current developments in healthcare are unprecedented. The organization of health care is complex. Collaboration is essential to meet all the healthcare needs of patients and to achieve coordinated and unambiguous information. Multiprofessional education (MPE) or multidisciplinary training (MDT) seems a logical step to stimulate teamwork. However, collaboration and MPE are wrestling with the same problems: social identity and acceptance. PMID:21818197

The impact of design-based modeling instruction on seventh graders' spatial abilities and model-based argumentation

NASA Astrophysics Data System (ADS)

McConnell, William J.

Due to the call of current science education reform for the integration of engineering practices within science classrooms, design-based instruction is receiving much attention in science education literature. Although some aspect of modeling is often included in well-known design-based instructional methods, it is not always a primary focus. The purpose of this study was to better understand how design-based instruction with an emphasis on scientific modeling might impact students' spatial abilities and their model-based argumentation abilities. In the following mixed-method multiple case study, seven seventh grade students attending a secular private school in the Mid-Atlantic region of the United States underwent an instructional intervention involving design-based instruction, modeling and argumentation. Through the course of a lesson involving students in exploring the interrelatedness of the environment and an animal's form and function, students created and used multiple forms of expressed models to assist them in model-based scientific argument. Pre/post data were collected through the use of The Purdue Spatial Visualization Test: Rotation, the Mental Rotation Test and interviews. Other data included a spatial activities survey, student artifacts in the form of models, notes, exit tickets, and video recordings of students throughout the intervention. Spatial abilities tests were analyzed using descriptive statistics while students' arguments were analyzed using the Instrument for the Analysis of Scientific Curricular Arguments and a behavior protocol. Models were analyzed using content analysis and interviews and all other data were coded and analyzed for emergent themes. Findings in the area of spatial abilities included increases in spatial reasoning for six out of seven participants, and an immense difference in the spatial challenges encountered by students when using CAD software instead of paper drawings to create models. Students perceived 3D printed models to better assist them in scientific argumentation over paper drawing models. In fact, when given a choice, students rarely used paper drawing to assist in argument. There was also a difference in model utility between the two different model types. Participants explicitly used 3D printed models to complete gestural modeling, while participants rarely looked at 2D models when involved in gestural modeling. This study's findings added to current theory dealing with the varied spatial challenges involved in different modes of expressed models. This study found that depth, symmetry and the manipulation of perspectives are typically spatial challenges students will attend to using CAD while they will typically ignore them when drawing using paper and pencil. This study also revealed a major difference in model-based argument in a design-based instruction context as opposed to model-based argument in a typical science classroom context. In the context of design-based instruction, data revealed that design process is an important part of model-based argument. Due to the importance of design process in model-based argumentation in this context, trusted methods of argument analysis, like the coding system of the IASCA, was found lacking in many respects. Limitations and recommendations for further research were also presented.

Social argumentation in online synchronous communication

NASA Astrophysics Data System (ADS)

Angiono, Ivan

In education, argumentation has an increasing importance because it can be used to foster learning in various fields including philosophy, history, sciences, and mathematics. Argumentation is also at the heart of scientific inquiry. Many educational technology researchers have been interested in finding out how technologies can be employed to improve students' learning of argumentation. Therefore, many computer-based tools or argumentation systems have been developed to assist students in their acquisition of argumentation skills. While the argumentation systems incorporating online debating tools present a good resource in formal settings, there is limited research revealing what argumentative skills students are portraying in informal online settings without the presence of a moderator. This dissertation investigates the nature of argumentative practices in a massively multiplayer online game where the system successfully incorporates the authentic use of online synchronous communication tools and the patterns that emerge from the interplay between a number of contextual variables including synchronicity, interest, authenticity, and topical knowledge.

Teaching Real Data Interpretation with Models (TRIM): Analysis of Student Dialogue in a Large-Enrollment Cell and Developmental Biology Course.

PubMed

Zagallo, Patricia; Meddleton, Shanice; Bolger, Molly S

2016-01-01

We present our design for a cell biology course to integrate content with scientific practices, specifically data interpretation and model-based reasoning. A 2-yr research project within this course allowed us to understand how students interpret authentic biological data in this setting. Through analysis of written work, we measured the extent to which students' data interpretations were valid and/or generative. By analyzing small-group audio recordings during in-class activities, we demonstrated how students used instructor-provided models to build and refine data interpretations. Often, students used models to broaden the scope of data interpretations, tying conclusions to a biological significance. Coding analysis revealed several strategies and challenges that were common among students in this collaborative setting. Spontaneous argumentation was present in 82% of transcripts, suggesting that data interpretation using models may be a way to elicit this important disciplinary practice. Argumentation dialogue included frequent co-construction of claims backed by evidence from data. Other common strategies included collaborative decoding of data representations and noticing data patterns before making interpretive claims. Focusing on irrelevant data patterns was the most common challenge. Our findings provide evidence to support the feasibility of supporting students' data-interpretation skills within a large lecture course. © 2016 P. Zagallo et al.

Evolution and convergence of the patterns of international scientific collaboration.

PubMed

Coccia, Mario; Wang, Lili

2016-02-23

International research collaboration plays an important role in the social construction and evolution of science. Studies of science increasingly analyze international collaboration across multiple organizations for its impetus in improving research quality, advancing efficiency of the scientific production, and fostering breakthroughs in a shorter time. However, long-run patterns of international research collaboration across scientific fields and their structural changes over time are hardly known. Here we show the convergence of international scientific collaboration across research fields over time. Our study uses a dataset by the National Science Foundation and computes the fraction of papers that have international institutional coauthorships for various fields of science. We compare our results with pioneering studies carried out in the 1970s and 1990s by applying a standardization method that transforms all fractions of internationally coauthored papers into a comparable framework. We find, over 1973-2012, that the evolution of collaboration patterns across scientific disciplines seems to generate a convergence between applied and basic sciences. We also show that the general architecture of international scientific collaboration, based on the ranking of fractions of international coauthorships for different scientific fields per year, has tended to be unchanged over time, at least until now. Overall, this study shows, to our knowledge for the first time, the evolution of the patterns of international scientific collaboration starting from initial results described by literature in the 1970s and 1990s. We find a convergence of these long-run collaboration patterns between the applied and basic sciences. This convergence might be one of contributing factors that supports the evolution of modern scientific fields.

Toward an experimental account of argumentation: the case of the slippery slope and the ad hominem arguments

PubMed Central

Lillo-Unglaube, Marco; Canales-Johnson, Andrés; Navarrete, Gorka; Bravo, Claudio Fuentes

2014-01-01

Argumentation is a crucial component of our lives. Although in the absence of rational debate our legal, political, and scientific systems would not be possible, there is still no integrated area of research on the psychology of argumentation. Furthermore, classical theories of argumentation are normative (i.e., the acceptability of an argument is determined by a set of norms or logical rules), which sometimes creates a dissociation between the theories and people’s behavior. We think the current challenge for psychology is to bring together the cognitive and normative accounts of argumentation. In this article, we exemplify this point by analyzing two cases of argumentative structures experimentally studied in the context of cognitive psychology. Specifically, we focus on the slippery slope argument and the ad hominem argument under the frameworks of Bayesian and pragma-dialectics approaches, respectively. We think employing more descriptive and experimental accounts of argumentation would help Psychology to bring closer the cognitive and normative accounts of argumentation with the final goal of establishing an integrated area of research on the psychology of argumentation.

Evaluating science arguments: evidence, uncertainty, and argument strength.

PubMed

Corner, Adam; Hahn, Ulrike

2009-09-01

Public debates about socioscientific issues are increasingly prevalent, but the public response to messages about, for example, climate change, does not always seem to match the seriousness of the problem identified by scientists. Is there anything unique about appeals based on scientific evidence-do people evaluate science and nonscience arguments differently? In an attempt to apply a systematic framework to people's evaluation of science arguments, the authors draw on the Bayesian approach to informal argumentation. The Bayesian approach permits questions about how people evaluate science arguments to be posed and comparisons to be made between the evaluation of science and nonscience arguments. In an experiment involving three separate argument evaluation tasks, the authors investigated whether people's evaluations of science and nonscience arguments differed in any meaningful way. Although some differences were observed in the relative strength of science and nonscience arguments, the evaluation of science arguments was determined by the same factors as nonscience arguments. Our results suggest that science communicators wishing to construct a successful appeal can make use of the Bayesian framework to distinguish strong and weak arguments. 2009 APA, all rights reserved

`Let your data tell a story:' climate change experts and students navigating disciplinary argumentation in the classroom

NASA Astrophysics Data System (ADS)

Walsh, Elizabeth Mary; McGowan, Veronica Cassone

2017-01-01

Science education trends promote student engagement in authentic knowledge in practice to tackle personally consequential problems. This study explored how partnering scientists and students on a social media platform supported students' development of disciplinary practice knowledge through practice-based learning with experts during two pilot enactments of a project-based curriculum focusing on the ecological impacts of climate change. Through the online platform, scientists provided feedback on students' infographics, visual argumentation artifacts that use data to communicate about climate change science. We conceptualize the infographics and professional data sets as boundary objects that supported authentic argumentation practices across classroom and professional contexts, but found that student generated data was not robust enough to cross these boundaries. Analysis of the structure and content of the scientists' feedback revealed that when critiquing argumentation, scientists initiated engagement in multiple scientific practices, supporting a holistic rather than discrete model of practice-based learning. While traditional classroom inquiry has emphasized student experimentation, we found that engagement with existing professional data sets provided students with a platform for developing expertise in systemic scientific practices during argument construction. We further found that many students increased the complexity and improved the visual presentation of their arguments after feedback.

[Scientific evidence on the legalization of abortion in Mexico City].

PubMed

Gayón-Vera, Eduardo

2010-03-01

On April 24 2007, abortion before 12 weeks became legal in Mexico City. The arguments for this decision were: diminish the maternal morbidity and mortality, avoid a "severe health problem" and accomplish the women's physical, mental and social well being. To analyze the scientific evidences that support or reject this arguments. Retrospective study realized by bibliographic search of electronic data basis and Internet portals of interested groups. Mexico is considered by the World Health Organization, one of the countries in the world with low maternal mortality rates (<100/100,000 live births). The main causes are: preeclampsia-eclampsia, pregnancy related hemorrhage, complications of pregnancy, delivery and puerperium, and other causes (92.2 to 93.1%). In 2007, the Health Services of Mexico City reported 11 deaths (0.03% of the total maternal deaths) associated with "non-spontaneous abortion". In the hospitals of the Mexican Institute of Social Security, maternal deaths as consequence of induced abortions were, approximately, three every year. The evidences used as arguments in favor of abortion come from studies performed in Sub-Saharan African countries, which do not apply to Mexico. The scientific evidences show that induced abortion has important psychological sequels in women, a higher frequency of illegal drug abuse, alcoholism, child abuse, low birth weight in the following pregnancy, greater risk of subsequent miscarriage and greater mortality rate. There are no scientific evidences to support the arguments used for the legal approval of abortion in Mexico City.

Finding effective ways of conserving large carnivores is widely recognised as a priority in conservation. However, there is disagreement about the most effective way to do this, with some favouring top-down 'command and control' approaches and others favouring collaboration. Arguments for coercive top-down approaches have been presented elsewhere; here we present arguments for collaboration. In many parts of the developed world, flexibility of approach is built into the legislation, so that conservation objectives are balanced with other legitimate goals. In the developing world, limited resources, poverty and weak governance mean that collaborative approaches are likely to play a particularly important part in carnivore conservation. In general, coercive policies may lead to the deterioration of political legitimacy and potentially to non-compliance issues such as illegal killing, whereas collaborative approaches may lead to psychological ownership, enhanced trust, learning, and better social outcomes. Sustainable hunting/trapping plays a crucial part in the conservation and management of many large carnivores. There are many different models for how to conserve carnivores effectively across the world, research is now required to reduce uncertainty and examine the effectiveness of these approaches in different contexts. © 2017 Cambridge Philosophical Society.

The nature and development of hypothetico-predictive argumentation with implications for science teaching

NASA Astrophysics Data System (ADS)

Lawson, Anton E.

2003-11-01

This paper explicates a pattern of scientific argumentation in which scientists respond to causal questions with the generation and test of alternative hypotheses through cycles of hypothetico-predictive argumentation. Hypothetico-predictive arguments are employed to test causal claims that exist on at least two levels (designated stage 4 in which the causal claims are perceptible, and stage 5 in which the causal claims are imperceptible). Origins of the ability to construct and comprehend hypothetico-predictive arguments at the highest level can be traced to pre-verbal reasoning of the sensory-motor child and the gradual internalization of verbally mediated arguments involving nominal, categorical, causal and, finally, theoretical propositions. Presumably, the ability to construct and comprehend hypothetico-predictive arguments (an aspect of procedural knowledge) is necessary for the construction of conceptual knowledge (an aspect of declarative knowledge) because such arguments are used during concept construction and conceptual change. Science instruction that focuses on the generation and debate of hypothetico-predictive arguments should improve students' conceptual understanding and their argumentative/reasoning skills.

A Safety Conundrum Illustrated: Logic, Mathematics, and Science Are Not Enough

Holloway, C. M.; Johnson, C. W.; Collins, Kristine R.

2010-01-01

In an ideal world, conversations about whether a particular system is safe, or whether a particular method or tool enhances safety, would be emotion-free discussions concentrating on the level of safety required, available evidence, and coherent logical, mathematical, or scientific arguments based on that evidence. In the real world, discussions about safety are often not emotion-free. Political and economic arguments may play a bigger role than logical, mathematical, and scientific arguments, and psychological factors may be as important, or even more important, than purely technical factors. This paper illustrates the conundrum that can result from this clash of the ideal and the real by means of an imagined conversation among a collection of fictional characters representing various types of people who may be participating in a safety discussion.

Argumentation in the Chemistry Laboratory: Inquiry and Confirmatory Experiments

Katchevich, Dvora; Hofstein, Avi; Mamlok-Naaman, Rachel

2013-02-01

One of the goals of science education is to provide students with the ability to construct arguments—reasoning and thinking critically in a scientific context. Over the years, many studies have been conducted on constructing arguments in science teaching, but only few of them have dealt with studying argumentation in the laboratory. Our research focuses on the process in which students construct arguments in the chemistry laboratory while conducting various types of experiments. It was found that inquiry experiments have the potential to serve as an effective platform for formulating arguments, owing to the features of this learning environment. The discourse during inquiry-type experiments was found to be rich in arguments, whereas that during confirmatory-type experiments was found to be sparse in arguments. The arguments, which were developed during the discourse of an open inquiry experiment, focus on the hypothesis-building stage, analysis of the results, and drawing appropriate conclusions.

1985-05-25

In one of a series of articles on philosophical medical ethics, Gillon rebuts the argument that moral claims are essentially different from scientific claims because scientific claims are objective and confirmable or refutable, while moral claims are subjective, unconfirmable, irrefutable, and their differences incapable of resolution. He contends that there is widespread agreement about many moral principles, that moral disagreement may arise from the use of ambiguous terminology, and that progress toward resolution may be accomplished by analysis of the logical validity and consistency of the arguments.

As cross-disciplinary research proliferates and becomes institutionalized globally, researchers will increasingly encounter the need to integrate their particular research perspectives within inquiries without sacrificing the potential contributions of their discipline-specific expertise. The work of the philosopher Bernard Lonergan (1904–1984) offers the necessary philosophical grounding. Here, I defend a role for philosophy in cross-disciplinary research and present selected ideas in Lonergan's work. These include: (1) a dynamic, normative pattern that each inquirer operates uniquely also forms the common core, or unity, in knowing; (2) the possibility of cross-disciplinary knowledge development is dependent on each researcher's consciousness of her or his attentiveness, intelligence, reasonableness, and responsibleness; and (3) shifts in researchers' viewpoints, or horizons, facilitate their collaborative inquiry and their grasp of the unity in knowing. The desire to know, shared by team members, drives their inquiry. Lonergan's stance is consistent with nursing values because it respects, but does not unconditionally privilege, any researcher or discipline. Arguments support a claim that Lonergan's perspective is well suited to guide nurse researchers participating on cross-disciplinary health research teams.

Dialectical Features of Students' Argumentation: A Critical Review of Argumentation Studies in Science Education

NASA Astrophysics Data System (ADS)

Nielsen, Jan Alexis

2013-02-01

This paper explores the challenges of using the Toulmin model to analyze students' dialogical argumentation. The paper presents a theoretical exposition of what is involved in an empirical study of real dialogic argumentation. Dialogic argumentation embodies dialectical features — i.e. the features that are operative when students collaboratively manage disagreement by providing arguments and engaging critically with the arguments provided by others. The paper argues that while dialectical features cannot readily be understood from a Toulminian perspective, it appears that an investigation of them is a prerequisite for conducting Toulminian analysis. This claim is substantiated by a detailed review of five of the ten most significant papers on students' argumentation in science education. This leads to the surprising notion that empirical studies in the argumentation strand — even those studies that have employed non-dialectical frameworks such as the Toulmin model — have implicitly struggled to come to terms with the dialectical features of students' discourse. The paper finally explores how some scholars have worked to attend directly to these dialectical features; and it presents five key issues that need to be addressed in a continued scholarly discussion.

Perceptions of the Nature and 'Goodness' of Argument among College Students, Science Teachers, and Scientists

NASA Astrophysics Data System (ADS)

Abi-El-Mona, Issam; Abd-El-Khalick, Fouad

2011-03-01

This study aimed to elucidate college freshmen science students, secondary science teachers, and scientists' perceptions of 'scientific' argument; to compare participants' perceptions with Stephen Toulmin's analytical framework of argument; and to characterize the criteria that participants deployed when assessing the 'quality' or 'goodness' of arguments. Thirty students, teachers, and scientists-with 10 members in each group-participated in two semi-structured individual interviews. During the first interview, participants generated an argument in response to a socioscientific issue. In the second interview, each participant 'evaluated' three arguments generated by a member from each participant group without being privy to the arguer's group membership. Interview transcripts were qualitatively analyzed. The findings point to both similarities and differences between participants' conceptions of argument and those based on Toulmin's analytical framework. Participants used an array of common and idiosyncratic criteria to judge the quality or goodness of argument. Finally, contrary to expectations, participants independently agreed that the 'best' arguments were those generated by participant science teachers.

Factors impacting teachers' argumentation instruction in their science classrooms

McNeill, Katherine L.; Katsh-Singer, Rebecca; González-Howard, María; Loper, Suzanna

2016-08-01

Science education research, reform documents and standards include scientific argumentation as a key learning goal for students. The role of the teacher is essential for implementing argumentation in part because their beliefs about argumentation can impact whether and how this science practice is integrated into their classroom. In this study, we surveyed 42 middle school science teachers and conducted follow-up interviews with 25 to investigate the factors that teachers believe impact their argumentation instruction. Teachers responded that their own learning goals had the greatest impact on their argumentation instruction while influences related to context, policy and assessment had the least impact. The minor influence of policy and assessment was in part because teachers saw a lack of alignment between these areas and the goals of argumentation. In addition, although teachers indicated that argumentation was an important learning goal, regardless of students' backgrounds and abilities, the teachers discussed argumentation in different ways. Consequently, it may be more important to help teachers understand what counts as argumentation, rather than provide a rationale for including argumentation in instruction. Finally, the act of trying out argumentation in their own classrooms, supported through resources such as curriculum, can increase teachers' confidence in teaching argumentation.

Scientific cooperation is essential for the advance of science. Bibliometrics and social network analysis offer evaluation indicators to analyse collaboration in scientific papers. The aim of this study is to characterize scientific collaboration patterns in Revista de Neurología between 2002 and 2006. Coauthorships and institutional relationships of papers published in Revista de Neurología have been identified. Collaboration Index, the most productive authors' and institutional collaboration patterns and the types of institutional collaborations have been quantified. Also, it has been constructed the coauthorship networks and the institutional collaboration network. Networks have been identified and represented using Access and Pajek software tools. The Collaboration Index was 4.01. 56.54% of papers involved institutional collaboration. The collaboration between institutions of the same country prevails (52.7%), followed by collaborations between departments, services or units of the same institution (40.47%) and international collaboration (6.83%). 45 coauthorship networks involving 149 investigators with a high intensity of collaboration and a large institutional network involved 80 centres were observed. Revista de Neurología covers scientific production of a high number of research groups. It has been observed a positive evolution in the collaboration patterns over the time. Nevertheless, it is essential to encourage inter-regional and international collaboration.

Does the world need a scientific society for research on how to improve healthcare?

PubMed Central

2012-01-01

In this editorial, we reflect on the arguments for starting a scientific society focused on research on how to improve healthcare. This society would take an inclusive approach to what constitutes healthcare. For instance, it should include mental health healthcare, treatment for substance abuse, the work of allied health professions, and preventive healthcare. The society would be open to researchers from all traditions. Thus, we take an inclusive approach to what constitutes scientific research, as long as it uses rigorous methods, is focused on improving healthcare, and aims at knowledge that can be transferred across settings. The society would primarily target scientific researchers but would invite others with an interest in this area of research, regardless of their discipline, position, field of application, or group affiliation (e.g., improvement science, behavioral medicine, knowledge translation). A society would need fruitful collaboration with related societies and organizations, which may include having combined meetings. Special links may be developed with one or more journals. A website to provide information on relevant resources, events, and training opportunities is another key activity. It would also provide a voice for the field at funding agencies, political arenas, and similar institutions. An organizational structure and financial resources are required to develop and run these activities. Our aim is to start an international debate, to discover if we can establish a shared vision across academics and stakeholders engaged with creating scientific knowledge on how to improve healthcare. We invite readers to express their views in the online questionnaire accessed by following the URL link provided at the end of the editorial. PMID:22376988

A New Virtual and Remote Experimental Environment for Teaching and Learning Science

NASA Astrophysics Data System (ADS)

Lustigova, Zdena; Lustig, Frantisek

This paper describes how a scientifically exact and problem-solving-oriented remote and virtual science experimental environment might help to build a new strategy for science education. The main features are: the remote observations and control of real world phenomena, their processing and evaluation, verification of hypotheses combined with the development of critical thinking, supported by sophisticated relevant information search, classification and storing tools and collaborative environment, supporting argumentative writing and teamwork, public presentations and defense of achieved results, all either in real presence, in telepresence or in combination of both. Only then real understanding of generalized science laws and their consequences can be developed. This science learning and teaching environment (called ROL - Remote and Open Laboratory), has been developed and used by Charles University in Prague since 1996, offered to science students in both formal and informal learning, and also to science teachers within their professional development studies, since 2003.

Mentoring and Argumentation in a Game-Infused Science Curriculum

Engaging in argumentation from evidence is challenging for most middle school students. We report the design of a media-based mentoring system to support middle school students in engaging in argumentation in the context of a game-infused science curriculum. Our design emphasizes learners apprenticing with college student mentors around the socio-scientific inquiry of a designed video game. We report the results of a mixed-methods study examining the use of this media-based mentoring system with students ages 11 through 14. We observed that the discourse of groups of students that engaged with the game-infused science curriculum while interacting with college student mentors via a social media platform demonstrated statistically significant higher ratings of cognitive, epistemic, and social aspects of argumentation than groups of students that engaged with the social media platform and game-infused science curriculum without mentors. We further explored the differences between the Discourses of the mentored and non-mentored groups. This analysis showed that students in the mentored groups were invited, guided, and socialized into roles of greater agency than students in the non-mentored groups. This increased agency might explain why mentored groups demonstrated higher levels of scientific argumentation than non-mentored groups. Based on our analyses, we argue that media-based mentoring may be designed around a video game to support middle school students in engaging in argumentation from evidence.

A critical component of science is the role of inquiry and argument in moving scientific knowledge forward. However, while students are expected to engage in inquiry activities in science classrooms, there is not always a similar emphasis on the role of argument within the inquiry activities. Building from previous studies on the Science Writing Heuristic (SWH), we were keen to find out if the writing structure used in the SWH approach helped students in Year 5, 7, and 10 to create well constructed arguments. We were also interested in examining which argument components were important for the quality of arguments generated by these students. Two hundred and ninety six writing samples were scored using an analysis framework to evaluate the quality of arguments. Step-wise multiple regression analyses were conducted to determine important argument components. The results of this study suggest that the SWH approach is useful in assisting students to develop reasonable arguments. The critical element determining the quality of the arguments is the relationship between the student’s written claims and his or her evidence.

Transparent collaboration between industry and academia can serve unmet patient need and contribute to reproductive public health

2017-01-01

Abstract The pharmaceutical and device industry has greatly contributed to diagnostic and therapeutic approaches in reproductive medicine in a very highly regulated environment, ensuring that development and manufacturing follow the highest standards. In spite of these achievements, collaboration between industry and physicians/academia is often presented in a negative context. However, today more than ever, partnership between industry and academia is needed to shorten the timeline between innovation and application, and to achieve faster access to better diagnostics, drugs and devices for the benefit of patients and society, based on complementary knowledge, skills and expertise. Such partnerships can include joined preclinical/clinical and post-marketing research and development, joint intellectual property, and joint revenue. In Europe, the transparency of this collaboration between pharmaceutical industry and medical doctors has been made possible by the Compliance and Disclosure Policy published by the European Federation of Pharmaceutical Industries and Associations (EFPIA), which represents the major pharmaceutical companies operating in Europe, and includes as members some but not all companies active in infertility and women's health. Under the EFPIA Disclosure Code of conduct, companies need to disclose transfers of value including amounts, activity type and the names of the recipient Health Care Professionals and Organizations. EFPIA member companies have also implemented very strict internal quality control processes and procedures in the design, statistical analysis, reporting, publication and communication of clinical research, according to Good Clinical Practice and other regulations, and are regularly inspected by competent authorities such as the US Food and Drug Administration (FDA) or European Medicines Agency (EMA) for all trials used in marketing authorization applications. The risk of scientific bias exists not only in the pharmaceutical industry but also in the academic world. When academics believe in a hypothesis, they may build their case by emphasizing the arguments supporting their case, and either refute, refuse, oppose or ignore arguments that challenge their assumptions. A possible solution to reduce this bias is international consensus on study design, data collection, statistical analysis and reporting of outcomes, especially in the area of personalized reproductive medicine, e.g. to demonstrate superiority or non-inferiority of personalized ovarian stimulation using biomarkers. Equally important is that declarations of interest are reported transparently and completely in scientific abstracts and publications, and that ghost authorship is replaced by proactive and clear co-authorship for experts from industry where such co-authorship is required based on the prevailing ICMJE criteria. In that context, however, reviewers should stop believing that publications by industry authors only, or by mixed groups of co-authors from industry and academia, are more prone to bias than papers from academic groups only. Instead, the scientific quality of the work should be the only relevant criterion for acceptance of papers or abstracts, regardless of the environment where the work was done. In the end, neutrality does not exist and different beliefs and biases exist within and between healthcare professionals and organizations and pharmaceutical industries. The challenge is to be transparent about this reality at all times, and to behave in an informed, balanced and ethical way as medical and scientific experts, taking into account compliance and legal regulations of both industry and academic employers, in the best interest of patients and society.

Science education as an exercise in foreign affairs

NASA Astrophysics Data System (ADS)

Cobern, William W.

1995-07-01

In Kuhnian terms, science education has been a process of inducting students into the reigning paradigms of science. In 1985, Duschl noted that science education had not kept pace with developments in the history and philosophy of science. The claim of certainty for scientific knowledge which science educators grounded in positivist philosophy was rendered untenable years ago and it turns out that social and cultural factors surrounding discovery may be at least as important as the justification of knowledge. Capitalizing on these new developments, Duschl, Hamilton, and Grandy (1990) wrote a compelling argument for the need to have a joint research effort in science education involving the philosophy and history of science along with cognitive psychology. However, the issue of discovery compels the research community go one step further. If the science education community has been guilty of neglecting historical and philosophical issues in science, let it not now be guilty of ignoring sociological issues in science. A collaborative view ought also to include the sociological study of cultural milieu in which scientific ideas arise. In other words, an external sociological perspective on science. The logic of discovery from a sociological point of view implies that conceptual change can also be viewed from a sociological perspective.

Questioning the evidence for a claim in a socio-scientific issue: an aspect of scientific literacy

NASA Astrophysics Data System (ADS)

Roberts, Ros; Gott, Richard

2010-11-01

Understanding the science in a 'socio-scientific issue' is at the heart of the varied definitions of 'scientific literacy'. Many consider that understanding evidence is necessary to participate in decision making and to challenge the science that affects people's lives. A model is described that links practical work, argumentation and scientific literacy which is used as the basis of this research. If students are explicitly taught about evidence does this transfer to students asking questions in the context of a local socio-scientific issue? What do they ask questions about? Sixty-five primary teacher training students were given the pre-test, before being taught the 'concepts of evidence' and applying them in an open-ended investigation and were tested again 15 weeks later. Data were coded using Toulmin's argument pattern (TAP) and the 'concepts of evidence'. After the intervention it was found that, in relation to a socio-scientific issue, they raised significantly more questions specifically about the evidence that lead to the scientists' claims although questions explicitly targeting the quality of the data were still rare. This has implications for curricula that aim for scientific literacy.

Arguments for amending smoke-free legislation in U.S. states to restrict use of electronic nicotine delivery systems.

The uneven diffusion of local and state laws restricting the use of electronic nicotine delivery systems (ENDS) in the United States may be a function of inconclusive scientific evidence and lack of guidance from the federal government. The objective of this study was to assess whether the rationale for amending clean indoor air acts (CIAAs) is being conflated by issues that are not directly relevant to protecting the health of ENDS non-users. Online sources were used in identifying bills ( n  = 25) that were presented in U.S. state legislatures from January 2009 to December 2015. The bills were categorized into one of three groups: 1) bills amending comprehensive CIAAs ( n  = 11), 2) bills prohibiting use of ENDS in places frequented by youth ( n  = 5), and 3) remaining bills that varied between the two categories ( n  = 9). Arguments presented in committee hearings were coded as scientific, public health, economic, enforcement, freedom, or regulatory. Arguments pertaining to amendment of clean indoor air acts spanned several categories, many of which were not directly relevant to the aims of the legislation. This finding could assist lawmakers and expert witnesses in making arguments that yield greater success in amending legislation. Alternatively, inconclusive scientific data on the hazards of ENDS aerosols might encourage lawmakers to propose legislation that prohibits ENDS use in places frequented by youths.

Bridging the knowledge gap: An analysis of Albert Einstein's popularized presentation of the equivalence of mass and energy.

PubMed

Kapon, Shulamit

2014-11-01

This article presents an analysis of a scientific article written by Albert Einstein in 1946 for the general public that explains the equivalence of mass and energy and discusses the implications of this principle. It is argued that an intelligent popularization of many advanced ideas in physics requires more than the simple elimination of mathematical formalisms and complicated scientific conceptions. Rather, it is shown that Einstein developed an alternative argument for the general public that bypasses the core of the formal derivation of the equivalence of mass and energy to provide a sense of derivation based on the history of science and the nature of scientific inquiry. This alternative argument is supported and enhanced by variety of explanatory devices orchestrated to coherently support and promote the reader's understanding. The discussion centers on comparisons to other scientific expositions written by Einstein for the general public. © The Author(s) 2013.

Wu, Ying; Duan, Zhiguang

2015-01-01

Mental disorder is harmful to human health, effects social life seriously and still brings a heavy burden for countries all over the world. Scientific collaboration has become the indispensable choice for progress in the field of biomedicine. However, there have been few scientific publications on scientific collaboration in psychiatry research so far. The aim of this study was to measure the activities of scientific collaboration in psychiatry research at the level of authors, institutions and countries. We retrieved 36557 papers about psychiatry from Science Ciation Index Expanded (SCI-Expanded) in web of science. Additionally, some methods such as social network analysis (SNA), K-plex analysis and Core-Periphery were used in this study. Collaboration has been increasing at the level of authors, institutions and countries in psychiatry in the last ten years. We selected the top 100 prolific authors, institutions and 30 countries to construct collaborative map respectively. Freedman, R and Seidman, LJ were the central authors, Harvard university was the central institution and the USA was the central country of the whole network. Notably, the rate of economic development of countries affected collaborative behavior. The results show that we should encourage multiple collaboration types in psychiatry research as they not only help researchers to master the current research hotspots but also provide scientific basis for clinical research on psychiatry and suggest policies to promote the development of this area.

Examining Science Teachers' Argumentation in a Teacher Workshop on Earthquake Engineering

NASA Astrophysics Data System (ADS)

Cavlazoglu, Baki; Stuessy, Carol

2018-02-01

The purpose of this study was to examine changes in the quality of science teachers' argumentation as a result of their engagement in a teacher workshop on earthquake engineering emphasizing distributed learning approaches, which included concept mapping, collaborative game playing, and group lesson planning. The participants were ten high school science teachers from US high schools who elected to attend the workshop. To begin and end the teacher workshop, teachers in small groups engaged in concept mapping exercises with other teachers. Researchers audio-recorded individual teachers' argumentative statements about the inclusion of earthquake engineering concepts in their concept maps, which were then analyzed to reveal the quality of teachers' argumentation. Toulmin's argumentation model formed the framework for designing a classification schema to analyze the quality of participants' argumentative statements. While the analysis of differences in pre- and post-workshop concept mapping exercises revealed that the number of argumentative statements did not change significantly, the quality of participants' argumentation did increase significantly. As these differences occurred concurrently with distributed learning approaches used throughout the workshop, these results provide evidence to support distributed learning approaches in professional development workshop activities to increase the quality of science teachers' argumentation. Additionally, these results support the use of concept mapping as a cognitive scaffold to organize participants' knowledge, facilitate the presentation of argumentation, and as a research tool for providing evidence of teachers' argumentation skills.

2013-08-10

Coronary heart disease (CHD) will continue to exert a heavy burden for countries all over the world. Scientific collaboration has become the only choice for progress in biomedicine. Unfortunately, there is a scarcity of scientific publications about scientific collaboration in CHD research. This study examines collaboration behaviors across multiple collaboration types in the CHD research. 294,756 records about CHD were retrieved from Web of Science. Methods such as co-authorship, social network analysis, connected component, cliques, and betweenness centrality were used in this study. Collaborations have increased at the author, institution and country/region levels in CHD research over the past three decades. 3000 most collaborative authors, 572 most collaborative institutions and 52 countries/regions are extracted from their corresponding collaboration network. 766 cliques are found in the most collaborative authors. 308 cliques are found in the most collaborative institutions. Western countries/regions represent the core of the world's collaboration. The United States ranks first in terms of number of multi-national publications, while Hungary leads in the ranking measured by their proportion of collaborative output. The rate of economic development in the countries/regions also affects the multi-national collaboration behavior. Collaborations among countries/regions need to be encouraged in the CHD research. The visualization of overlapping cliques in the most collaborative authors and institutions are considered "skeleton" of the collaboration network. Eastern countries/regions should strengthen cooperation with western countries/regions in the CHD research. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Collaboration Networks in the Brazilian Scientific Output in Evolutionary Biology: 2000-2012.

PubMed

Santin, Dirce M; Vanz, Samile A S; Stumpf, Ida R C

2016-03-01

This article analyzes the existing collaboration networks in the Brazilian scientific output in Evolutionary Biology, considering articles published during the period from 2000 to 2012 in journals indexed by Web of Science. The methodology integrates bibliometric techniques and Social Network Analysis resources to describe the growth of Brazilian scientific output and understand the levels, dynamics and structure of collaboration between authors, institutions and countries. The results unveil an enhancement and consolidation of collaborative relationships over time and suggest the existence of key institutions and authors, whose influence on research is expressed by the variety and intensity of the relationships established in the co-authorship of articles. International collaboration, present in more than half of the publications, is highly significant and unusual in Brazilian science. The situation indicates the internationalization of scientific output and the ability of the field to take part in the science produced by the international scientific community.

Socioscientific Argumentation of Pre-Service Teachers about Genetically Modified Organisms

Herawati, D.; Ardianto, D.

2017-09-01

This study aims to investigate socioscientific argumentation of pre-service teachers of science and non-science major regarding Genetically Modified Organisms (GMOs) issue. We used descriptive study and involved second-year pre-service teachers from two major, 28 pre-service science teachers (PSTs) and 28 pre-service non-science teachers (PNSTs) as participants. Paper and pencil test was administered in order to obtain the data of PSTs’ and PNSTs’ argument about GMOs. All of the data were analyzed by descriptive analysis. We applied Toulmin Argumentation Pattern (TAP) as a basic framework to identify the argumentation component. The result showed that both PSTs and PNSTs were able to propose an argument with a claim, data, and/or warrant.. Most of their argument contain data which provided in the text, without any further reasoning or relevant scientific knowledge. So, the coherency between argumentation component in both PSTs and PNSTs was limited. However, PSTs are more able to propose coherent arguments than PNSTs. These findings indicated that educational background and learning experiences may influence to pre-service teacher argumentation in the context of GMOs. Beside that, teaching and learning process which focused on the socioscientific issues is necessary to develop pre-service teachers’ argumentation

Forging a link between mentoring and collaboration: a new training model for implementation science.

2016-10-13

Training investigators for the rapidly developing field of implementation science requires both mentoring and scientific collaboration. Using social network descriptive analyses, visualization, and modeling, this paper presents results of an evaluation of the mentoring and collaborations fostered over time through the National Institute of Mental Health (NIMH) supported by Implementation Research Institute (IRI). Data were comprised of IRI participant self-reported collaborations and mentoring relationships, measured in three annual surveys from 2012 to 2014. Network descriptive statistics, visualizations, and network statistical modeling were conducted to examine patterns of mentoring and collaboration among IRI participants and to model the relationship between mentoring and subsequent collaboration. Findings suggest that IRI is successful in forming mentoring relationships among its participants, and that these mentoring relationships are related to future scientific collaborations. Exponential random graph network models demonstrated that mentoring received in 2012 was positively and significantly related to the likelihood of having a scientific collaboration 2 years later in 2014 (p = 0.001). More specifically, mentoring was significantly related to future collaborations focusing on new research (p = 0.009), grant submissions (p = 0.003), and publications (p = 0.017). Predictions based on the network model suggest that for every additional mentoring relationships established in 2012, the likelihood of a scientific collaboration 2 years later is increased by almost 7 %. These results support the importance of mentoring in implementation science specifically and team science more generally. Mentoring relationships were established quickly and early by the IRI core faculty. IRI fellows reported increasing scientific collaboration of all types over time, including starting new research, submitting new grants, presenting research results, and publishing peer-reviewed papers. Statistical network models demonstrated that mentoring was strongly and significantly related to subsequent scientific collaboration, which supported a core design principle of the IRI. Future work should establish the link between mentoring and scientific productivity. These results may be of interest to team science, as they suggest the importance of mentoring for future team collaborations, as well as illustrate the utility of network analysis for studying team characteristics and activities.

Applying Bradford Hill's criteria for causation to neuropsychiatry: challenges and opportunities.

PubMed

van Reekum, R; Streiner, D L; Conn, D K

2001-01-01

Establishing an argument of causation is an important research activity with major clinical and scientific implications. Sir Austin Bradford Hill proposed criteria to establish such an argument. These criteria include the strength of the association, consistency, specificity, temporal sequence, biological gradient, biologic rationale, coherence, experimental evidence, and analogous evidence. These criteria are reviewed with the goal of facilitating an increase in rigor for establishing arguments of causation in neuropsychiatry. The challenges and opportunities related to these criteria in neuropsychiatry are reviewed, as are two important arguments for causation: one for poststroke depression and one for brain injury as a cause of psychiatric disorders.

Science Teaching and Argumentation: One-sided versus dialectical argumentation in Chilean middle-school science lessons

Larrain, Antonia; Freire, Paulina; Howe, Christine

2014-04-01

Since the late 1990s, there has been consensus among educational researchers that argumentation should play a central role in science education. Although there has been extensive relevant research, it is not clear enough how oral argumentation spontaneously occurs in science teaching. This is particularly important with regard to the empirical evidence suggesting the effect of discussion of contradictory views on scientific learning. In order to contribute to the research on argumentation in science teaching, we conducted a study that aims to sketch a panoramic view of the uses of oral argumentation in Chilean middle-school science teaching. A total of 153 videotaped science lessons were observed, involving students aged 10-11 and 12-13. Whole-class argumentative discourse was analysed as a function of thematic episodes and teachers' and students' utterances. Results suggest that argumentative discourse in which contradictory points of view are discussed is scarce but when it occurs it does so predominantly within discourse among students. On the contrary, argumentation aimed at justifying points of view is widely used, even more so when students are older.

Guan, Jiancheng; Liu, Na

2014-04-01

The purpose of this paper is to comprehensively explore scientific research profiles in the field of emerging nano-energy during 1991-2012 based on bibliometrics and social network analysis. We investigate the growth pattern of research output, and then carry out across countries/regions comparisons on research performances. Furthermore, we examine scientific collaboration across countries/regions by analyzing collaborative intensity and networks in 3- to 4-year intervals. Results indicate with an impressively exponential growth pattern of nano-energy articles, the world share of scientific "giants," such as the USA, Germany, England, France and Japan, display decreasing research trends, especially in the USA. Emerging economies, including China, South Korea and India, exhibit a rise in terms of the world share, illustrating strong development momentum of these countries in nano-energy research. Strikingly, China displays a remarkable rise in scientific influence rivaling Germany, Japan, France, and England in the last few years. Finally, the scientific collaborative network in nano-energy research has expanded steadily. Although the USA and several major European countries play significantly roles on scientific collaboration, China and South Korea exert great influence on scientific collaboration in recent years. The findings imply that emerging economies can earn competitive advantages in some emerging fields by properly engaging a catch-up strategy.

Fourth, I illustrate how false beliefs can promote scientific progress in ways that cannot be explicated by appeal to verisimilitude. Copyright © 2015 Elsevier Ltd. All rights reserved.

Network effects on scientific collaborations.

PubMed

Uddin, Shahadat; Hossain, Liaquat; Rasmussen, Kim

2013-01-01

The analysis of co-authorship network aims at exploring the impact of network structure on the outcome of scientific collaborations and research publications. However, little is known about what network properties are associated with authors who have increased number of joint publications and are being cited highly. Measures of social network analysis, for example network centrality and tie strength, have been utilized extensively in current co-authorship literature to explore different behavioural patterns of co-authorship networks. Using three SNA measures (i.e., degree centrality, closeness centrality and betweenness centrality), we explore scientific collaboration networks to understand factors influencing performance (i.e., citation count) and formation (tie strength between authors) of such networks. A citation count is the number of times an article is cited by other articles. We use co-authorship dataset of the research field of 'steel structure' for the year 2005 to 2009. To measure the strength of scientific collaboration between two authors, we consider the number of articles co-authored by them. In this study, we examine how citation count of a scientific publication is influenced by different centrality measures of its co-author(s) in a co-authorship network. We further analyze the impact of the network positions of authors on the strength of their scientific collaborations. We use both correlation and regression methods for data analysis leading to statistical validation. We identify that citation count of a research article is positively correlated with the degree centrality and betweenness centrality values of its co-author(s). Also, we reveal that degree centrality and betweenness centrality values of authors in a co-authorship network are positively correlated with the strength of their scientific collaborations. Authors' network positions in co-authorship networks influence the performance (i.e., citation count) and formation (i.e., tie strength) of scientific collaborations.

2013-05-01

The argument advanced by Giubilini and Minerva is an important one, but it suffers from some shortcomings. I briefly criticise their reasoning and method and argue that after birth abortion should be limited largely to infants with disabilities. My argument is based not on solid scientific evidence or cold rational reasoning but on intuition, something that has long been discounted as irrelevant in biomedical discourse. I end with a recommendation to all of us: in order to make a change, one should not only choose one's battles, but also one's weapon and mode of attack.

A Framework for Practical Work in Science and Scientific Literacy through Argumentation

ERIC Educational Resources Information Center

Gott, R.; Duggan, S.

2007-01-01

This paper draws on earlier work on ideas that underpin the collection and use of evidence in science in schools. It establishes that different types of practical work share the same procedural underpinnings. It then takes the work of Toulmin on argumentation to suggest that the idea of the "public claim" can be used to forge a link…

Reflections on writing hydrologic reports

USGS Publications Warehouse

Olcott, Perry G.

1987-01-01

Reporting of scientific work should be characterized by a logical argument that is developed through presentation of the problem, tabulation and display of data pertinent to the problem , and testing and interpretation of the data to prove hypotheses that address the problem. Organization of the report is vital to developing this logical argument: it provides structure, continuity, logic, and emphasis to the presentation. Each part of the report serves a specific function and each is linked by a connecting logic, the logical argument of the report. Each scientific report normally has a title, table of contents, abstract, introduction, body (of the report), and summary and/or conclusions. Organization of sections within the body of the report is exactly parallel to overall organization; subjects presented in the section title are developed by logical subdivisions and pertinent discussion. The summary and/or conclusions section culminates the logical argument of the report by drawing together and quantitatively reiterating the principal conclusions developed in the discussion. Supplemental information on report content, background of the study, additional data or details on procedures, and other information of interest to the reader is presented in the foreward or preface, list of illustrations or tables, glossaries, and appendixes.

How medical specialists appraise three controversial health innovations: scientific, clinical and social arguments.

PubMed

Lehoux, Pascale; Denis, Jean-Louis; Rock, Melanie; Hivon, Myriam; Tailliez, Stephanie

2010-01-01

Medical specialists play a pivotal role in health innovation evaluation and policy making. Their influence derives not only from their expertise, but also from their social status and the power of their professional organisations. Little is known, however, about how medical specialists determine what makes a health innovation desirable and why. Our qualitative study investigated the views of 28 medical specialists and experts from Quebec and Ontario (Canada) on three controversial innovations: electroconvulsive therapy, prostate-specific antigen screening and prenatal screening for Down's syndrome. Our findings indicate that the scientific, clinical and social arguments of medical specialists combine to create a relatively consistent narrative for each innovation. Our comparative analysis suggests that these narratives bring about a 'soft' resolution to controversies, which relies on a more or less tacit understanding of the social desirability of innovations and which sets the stage for their routinisation. Such an unpacking of medical specialists' arguments both for and against new technologies is needed because such arguments may easily be considered authoritative and because there are few forums for debating the social desirability of innovations not generally deemed to be highly controversial.

David Hull's generalized natural selection as an explanation for scientific change

NASA Astrophysics Data System (ADS)

Little, Michelle Yvette

2001-10-01

Philosophers of science such as Karl Popper and Thomas Kuhn have employed evolutionary idiom in describing scientific change. In Science as a Process (1988) Hull makes evolutionary theory explanatorily applicable. He modifies key evolutionary terms in order that both biological evolution and scientific change are instances of a general selection process. According to Hull, because of naturally-existing competition for credit among researchers and the professional lineages they constitute, scientists are constrained to cooperate and collaborate. This process entails two important philosophical consequences. First, it allows for a natural justification of why the sciences can provide objective empirical knowledge. Second, appreciating its strength means that a philosophical analysis of scientific change is solidly difficult features to combine. I work on strengthening two weaknesses in Hull's arguments. First, operating in his analysis is an unexplicated notion of ``information'' running parallel to the equally opaque notion of genetic information. My third chapter provides a clear account of ``genetic information'' whose usefulness extends beyond the assistance it can render Hull as a clear concept is needed in biological contexts as well. The fourth and fifth chapters submit evidence of scientific change from radio astronomy. Hull insists on empirical backing for philosophical theses but his own book stands to suffer from selection effects as it offers cases drawn from a single subspecialty in the biological sciences. I found that in the main scientists and the change they propel accords well with Hull's explanation. However, instances of major change reveal credit- and resource-sharing to a degree contrary with what Hull would expect. My conclusion is that the naturalness of competition, instantiated during the course of standardized and relatively ``normal'' scientific research, is not the norm during periods of new research and its uncertain standards of protocol. As such my position is an inversion of the relationship Hull views between cooperation and competition in scientific change. Cooperation is a precondition for competition, rather than the other way around.

Did Ptolemy make novel predictions? Launching Ptolemaic astronomy into the scientific realism debate.

PubMed

Carman, Christián; Díez, José

2015-08-01

The goal of this paper, both historical and philosophical, is to launch a new case into the scientific realism debate: geocentric astronomy. Scientific realism about unobservables claims that the non-observational content of our successful/justified empirical theories is true, or approximately true. The argument that is currently considered the best in favor of scientific realism is the No Miracles Argument: the predictive success of a theory that makes (novel) observational predictions while making use of non-observational content would be inexplicable unless such non-observational content approximately corresponds to the world "out there". Laudan's pessimistic meta-induction challenged this argument, and realists reacted by moving to a "selective" version of realism: the approximately true part of the theory is not its full non-observational content but only the part of it that is responsible for the novel, successful observational predictions. Selective scientific realism has been tested against some of the theories in Laudan's list, but the first member of this list, geocentric astronomy, has been traditionally ignored. Our goal here is to defend that Ptolemy's Geocentrism deserves attention and poses a prima facie strong case against selective realism, since it made several successful, novel predictions based on theoretical hypotheses that do not seem to be retained, not even approximately, by posterior theories. Here, though, we confine our work just to the detailed reconstruction of what we take to be the main novel, successful Ptolemaic predictions, leaving the full analysis and assessment of their significance for the realist thesis to future works.

Leone Sciabolazza, Valerio; Vacca, Raffaele; Kennelly Okraku, Therese; McCarty, Christopher

2017-01-01

A growing body of evidence shows that collaborative teams and communities tend to produce the highest-impact scientific work. This paper proposes a new method to (1) Identify collaborative communities in longitudinal scientific networks, and (2) Evaluate the impact of specific research institutes, services or policies on the interdisciplinary collaboration between these communities. First, we apply community-detection algorithms to cross-sectional scientific collaboration networks and analyze different types of co-membership in the resulting subgroups over time. This analysis summarizes large amounts of longitudinal network data to extract sets of research communities whose members have consistently collaborated or shared collaborators over time. Second, we construct networks of cross-community interactions and estimate Exponential Random Graph Models to predict the formation of interdisciplinary collaborations between different communities. The method is applied to longitudinal data on publication and grant collaborations at the University of Florida. Results show that similar institutional affiliation, spatial proximity, transitivity effects, and use of the same research services predict higher degree of interdisciplinary collaboration between research communities. Our application also illustrates how the identification of research communities in longitudinal data and the analysis of cross-community network formation can be used to measure the growth of interdisciplinary team science at a research university, and to evaluate its association with research policies, services or institutes.

Learning to Teach Argumentation: Research and development in the science classroom

Simon, Shirley; Erduran, Sibel; Osborne, Jonathan

2006-02-01

The research reported in this study focuses on an investigation into the teaching of argumentation in secondary science classrooms. Over a 1-year period, a group of 12 teachers from schools in the greater London area attended a series of workshops to develop materials and strategies to support the teaching of argumentation in scientific contexts. Data were collected at the beginning and end of the year by audio-recording and video-recording lessons where the teachers attempted to implement argumentation. To assess the quality of argumentation, analytical tools derived from Toulmin’s argument pattern were developed and applied to classroom transcripts. Teachers’ use of argumentation developed across the year, the pattern of use was teacher-specific, as was the nature of change. To inform future professional development programmes, transcripts of five teachers, three showing a significant change and two showing no change, were analysed in more detail to identify features of teachers’ oral contributions that facilitated and supported argumentation. All teachers attempted to encourage a variety of processes involved in argumentation; teachers whose lessons included the highest quality of argumentation (Toulmin’s argument pattern analysis) also encouraged higher-order processes in their teaching. The analysis of teachers’ facilitation of argumentation has helped to guide the development of in-service materials and to identify the barriers to learning in the professional development of less experienced teachers.

Argumentation in Science Class: Its Planning, Practice, and Effect on Student Motivation

NASA Astrophysics Data System (ADS)

Taneja, Anju

Studies have shown an association between argumentative discourse in science class, better understanding of science concepts, and improved academic performance. However, there is lack of research on how argumentation can increase student motivation. This mixed methods concurrent nested study uses Bandura's construct of motivation and concepts of argumentation and formative feedback to understand how teachers orchestrate argumentation in science class and how it affects motivation. Qualitative data was collected through interviews of 4 grade-9 science teachers and through observing teacher-directed classroom discourse. Classroom observations allowed the researcher to record the rhythm of discourse by characterizing teacher and student speech as teacher presentation (TP), teacher guided authoritative discussion (AD), teacher guided dialogic discussion (DD), and student initiation (SI). The Student Motivation Towards Science Learning survey was administered to 67 students before and after a class in which argumentation was used. Analysis of interviews showed teachers collaborated to plan argumentation. Analysis of discourse identified the characteristics of argumentation and provided evidence of students' engagement in argumentation in a range of contexts. Student motivation scores were tested using Wilcoxon signed rank tests and Mann-Whitney U-tests, which showed no significant change. However, one construct of motivation---active learning strategy---significantly increased. Quantitative findings also indicate that teachers' use of multiple methods in teaching science can affect various constructs of students' motivation. This study promotes social change by providing teachers with insight about how to engage all students in argumentation.

The Interplay between Scientific Overlap and Cooperation and the Resulting Gain in Co-Authorship Interactions.

PubMed

Mayrose, Itay; Freilich, Shiri

2015-01-01

Considering the importance of scientific interactions, understanding the principles that govern fruitful scientific research is crucial to policy makers and scientists alike. The outcome of an interaction is to a large extent dependent on the balancing of contradicting motivations accompanying the establishment of collaborations. Here, we assembled a dataset of nearly 20,000 publications authored by researchers affiliated with ten top universities. Based on this data collection, we estimated the extent of different interaction types between pairwise combinations of researchers. We explored the interplay between the overlap in scientific interests and the tendency to collaborate, and associated these estimates with measures of scientific quality and social accessibility aiming at studying the typical resulting gain of different interaction patterns. Our results show that scientists tend to collaborate more often with colleagues with whom they share moderate to high levels of mutual interests and knowledge while cooperative tendency declines at higher levels of research-interest overlap, suggesting fierce competition, and at the lower levels, suggesting communication gaps. Whereas the relative number of alliances dramatically differs across a gradient of research overlap, the scientific impact of the resulting articles remains similar. When considering social accessibility, we find that though collaborations between remote researchers are relatively rare, their quality is significantly higher than studies produced by close-circle scientists. Since current collaboration patterns do not necessarily overlap with gaining optimal scientific quality, these findings should encourage scientists to reconsider current collaboration strategies.

Collaborative exams: Cheating? Or learning?

NASA Astrophysics Data System (ADS)

Jang, Hyewon; Lasry, Nathaniel; Miller, Kelly; Mazur, Eric

2017-03-01

Virtually all human activity involves collaboration, and yet, collaboration during an examination is typically considered cheating. Collaborative assessments have not been widely adopted because of the perceived lack of individual accountability and the notion that collaboration during assessments simply causes propagation of correct answers. Hence, collaboration could help weaker students without providing much benefit to stronger students. In this paper, we examine student performance in open-ended, two-stage collaborative assessments comprised of an individually accountable round followed by an automatically scored, collaborative round. We show that collaboration entails more than just propagation of correct answers. We find greater rates of correct answers after collaboration for all students, including the strongest members of a team. We also find that half of teams that begin without a correct answer to propagate still obtain the correct answer in the collaborative round. Our findings, combined with the convenience of automatic feedback and grading of open-ended questions, provide a strong argument for adopting collaborative assessments as an integral part of education.

Distributed Deliberative Recommender Systems

Case-Based Reasoning (CBR) is one of most successful applied AI technologies of recent years. Although many CBR systems reason locally on a previous experience base to solve new problems, in this paper we focus on distributed retrieval processes working on a network of collaborating CBR systems. In such systems, each node in a network of CBR agents collaborates, arguments and counterarguments its local results with other nodes to improve the performance of the system's global response. We describe D2ISCO: a framework to design and implement deliberative and collaborative CBR systems that is integrated as a part of jcolibritwo an established framework in the CBR community. We apply D2ISCO to one particular simplified type of CBR systems: recommender systems. We perform a first case study for a collaborative music recommender system and present the results of an experiment of the accuracy of the system results using a fuzzy version of the argumentation system AMAL and a network topology based on a social network. Besides individual recommendation we also discuss how D2ISCO can be used to improve recommendations to groups and we present a second case of study based on the movie recommendation domain with heterogeneous groups according to the group personality composition and a group topology based on a social network.

A survey of scientific production and collaboration rate among of medical library and information sciences in ISI, scopus and Pubmed databases during 2001-2010.

Research is essential for development. In other words, scientific development of each country can be evaluated by researchers' scientific production. Understanding and assessing the activities of researchers for planning and policy making is essential. The significance of collaboration in the production of scientific publications in today's complex world where technology is everything is very apparent. Scientists realized that in order to get their work wildly used and cited to by experts, they must collaborate. The collaboration among researchers results in the development of scientific knowledge and hence, attainment of wider information. The main objective of this research is to survey scientific production and collaboration rate in philosophy and theoretical bases of medical library and information sciences in ISI, SCOPUS, and Pubmed databases during 2001-2010. This is a descriptive survey and scientometrics methods were used for this research. Then data gathered via check list and analyzed by the SPSS software. Collaboration rate was calculated according to the formula. Among the 294 related abstracts about philosophy, and theoretical bases of medical library and information science in ISI, SCOPUS, and Pubmed databases during 2001-2010, the year 2007 with 45 articles has the most and the year 2003 with 16 articles has the least number of related collaborative articles in this scope. "B. Hjorland" with eight collaborative articles had the most one among Library and Information Sciences (LIS) professionals in ISI, SCOPUS, and Pubmed. Journal of Documentation with 29 articles and 12 collaborative articles had the most related articles. Medical library and information science challenges with 150 articles had first place in number of articles. Results also show that the most elaborative country in terms of collaboration point of view and number of articles was US. "University of Washington" and "University Western Ontario" are the most elaborative affiliation from a collaboration point. The average collaboration rate between researchers in this field during the years studied is 0.25. The most completive reviewed articles are single authors that included 60.54% of the whole articles. Only 30.46% of articles were provided with two or more than two authors.

Teaching and Learning the Elements of Argumentation

NASA Astrophysics Data System (ADS)

Untereiner, Brian

Kim, Department of Curriculum and Instruction Departmental Member iii Abstract Supervisory Committee Dr. Robert Anthony, Department of Curriculum and Instruction Supervisor Dr. Mijung Kim, Department of Curriculum and Instruction Departmental Member In this study I investigated the interactions of 25 Grade 8 science students as they learned how to construct oral arguments using the Toulmin Argumentation Pattern framework. I collected the data during three recorded small group discussion sessions during a five week Earth Science unit between February and March of 2011. The first session recorded the students' discussions prior to receiving either argumentation instruction or the science concept instruction. The second session recorded their discussions after receiving an introduction to argumentation and a scaffold, but not concept instruction. During the three weeks preceding the third session, the students received additional argumentation instruction and completed one-third of the Earth Science unit. The results showed the students collectively made more arguments during each subsequent session. The students' individual arguments showed a correspondence between their purportedly most familiar topics and the most discussed topics. I also found that when students made counter arguments and/or invited or challenged group members to participate, their discussions contained comparatively more argument elements (claims, data and warrants) than discussions containing predominantly collaborative assertions. The key outcome of this study for developing students' use of the elements of argumentation during classroom discussions was to recognize and incorporate opportunities for the students to tap into their prior-knowledge. To engage students in this process, the results indicate the importance of creating time for discussions relevant to the curriculum and to the students.

On enrolling more female students in science and engineering.

PubMed

Bouville, Mathieu

2008-06-01

Many people hold this truth to be self-evident that universities should enroll more female students in science and engineering; the main question then being how. Typical arguments include possible benefits to women, possible benefits to the economy, and the unfairness of the current female under-representation. However, when clearly stated and scrutinized these arguments in fact lead to the conclusion that there should be more women in scientific disciplines in higher education in the sense that we should expect more women (which various kinds of discrimination may prevent), not that we should actively enroll more women. Outreach programs towards high school students may therefore be logically incompatible with the arguments supposed to justify them. They should purport to allow women to graduate in a field congruent with her abilities and desires, rather than try to draw as many of them to scientific disciplines as possible: one cannot try to 'recruit' as many female students as possible while claiming to help them choose more freely.

The objectives of this paper are to analyze the Spanish scientific production in nursing, define its temporal evolution, its geographical and institutional distribution, and observe the interinstitutional collaboration. We analyze a comprehensive sample of Spanish scientific production in the nursing area extracted from the multidisciplinary database SciVerse Scopus. The nursing scientific production grows along time. The collaboration rate is 3.7 authors per paper and 61% of the authors only publish one paper. Barcelona and Madrid are the provinces with highest number of authors. Most belong to the hospitalary environment, followed closely by authors belonging to the university. The most institutions that collaborate, sharing authorship of articles are: University of Barcelona, Autonomous University of Barcelona and Clinic Hospital of Barcelona. The nursing scientific production has been increasing since her incorporation at the university. The collaboration rate found is higher than found for other papers. It shows a low decrease of occasional authors. It discusses the outlook of scientific collaboration in nursing in Spain, at the level of institutions by co-authorship of papers, through a network graph. It observes their distribution, importance and interactions or lack thereof. There is a strong need to use international databases for research, care and teaching, in addition to the national specialized information resources. Professionals are encouraged to normalization of the paper's signature, both, surnames and institutions to which they belong. It confirms the limited cooperation with foreign institutions, although there is an increasing trend of collaboration between Spanish authors in this discipline. It is observed, clearly defined three interinstitutional collaboration patterns. Copyright © 2012 Elsevier España, S.L. All rights reserved.

What is "good reasoning" about global warming? A comparison of high school students and specialists

NASA Astrophysics Data System (ADS)

Adams, Stephen Thomas

This study compares the knowledge and reasoning about global warming of 10 twelfth grade students and 6 specialists, including scientists and policy analysts. The study uses global warming as a context for addressing the broad objective of formulating goals for scientific literacy. Subjects evaluated a set of articles about global warming and evaluated policies proposed to ameliorate global warming, including a gasoline tax and a "feebate" system of fees and rebates on automobiles. All students and one scientist participated in a full treatment involving interviews and activities with a computer program (discussed below), averaging about 3.75 hours. In addition, five specialists participated in interviews only, averaging one hour. One line of analysis focuses on knowledge content, examining how subjects applied perspectives from both natural and social sciences. This analysis is positioned as an empirical component to the movement to develop content standards for science education, as exemplified by the recommendations of Science for All Americans (SFAA). Some aspects of competent performance in the present study hinged upon knowledge and skills advocated by SFAA (e.g., fluency with themes of science such as scale). Other aspects involved such skills as evaluating economic interests behind a scientific argument in the media or considering hidden costs in a policy area. By characterizing a range of approaches to how students and specialists performed the experimental tasks, the present study affords a view of scientific literacy not possible without this type of information. Another line of analysis investigates a measure of coherent argumentation from a computer program, Convince Me, in relation to policy reasoning. The program is based on a connectionist model, ECHO. Subjects used the program to create arguments about the aforementioned policies. The study compares Convince Me's Model's Fit argumentation measure to other measures, including ratings of 6 human judges about the quality of the arguments, a measure of the stability of subjects' views, and the number of statements in subjects' arguments. The pattern of significant correlations among several of these measures, plus interview findings, help to clarify cognitive and educational issues involved with using Convince Me (or related programs) in this area.

Optimizing the orchestration of resemiotization with teacher "talk moves": A model of guided-inquiry instruction in middle school science

NASA Astrophysics Data System (ADS)

Millstone, Rachel Diana

The current conceptualization of science set forth by the National Research Council (2008) is one of science as a social activity, rather than a view of science as a fixed body of knowledge. This requires teachers to consider how communication, processing, and meaning-making contribute to science learning. It also requires teachers to think deeply about what constitutes knowledge and understanding in science, and what types of instruction are most conducive to preparing students to participate meaningfully in the society of tomorrow. Because argumentation is the prominent form of productive talk leading to the building of new scientific knowledge, one indicator of successful inquiry lies in students' abilities to communicate their scientific understandings in scientific argumentation structures. The overarching goal of this study is to identify factors that promote effective inquiry-based instruction in middle school science classrooms, as evidenced in students' abilities to engage in quality argumentation with their peers. Three specific research questions were investigated: (1) What factors do teachers identify in their practice as significant to the teaching and learning of science? (2) What factors do students identify as significant to their learning of science? and (3) What factors affect students' opportunities and abilities to achieve sophisticated levels of argumentation in the classroom? Two teachers and forty students participated in this study. Four principle sources of data were collected over a three-month period of time. These included individual teacher interviews, student focus group interviews, fieldnotes, and approximately 85 hours of classroom videotape. From this sample, four pathways for guided-inquiry instruction are identified. Opportunities for student talk were influenced by a combination of factors located in the domains of "teacher practice," "classroom systems," and "physical structures." Combinations of elements from these three dimensions also affected the quality of student argumentation, as measured on a five-point rubric developed for analysis. Of the four pathways, one in particular is identified as a model of "best practice," leading to the highest levels of argumentation resulting from opportunities for student resemiotization mediated by teacher "talk moves."

Making sense scientific claims in advertising. A study of scientifically aware consumers.

Dodds, Rachel E; Tseëlon, Efrat; Weitkamp, Emma L C

2008-04-01

Evidence that science is becoming increasingly embedded in culture comes from the proliferation of discourses of ethical consumption, sustainability, and environmental awareness. Al Gore's recent award, along with UN's Inter-governmental Panel on Climate Change (IPCC) of the Nobel peace prize-- provided a recent high profile linking of consumption and science. It is not clear to what extent the public at large engages in evaluating the scientific merits of the arguments about the link between human consumption and global environmental catastrophes. But on a local scale, we are routinely required to evaluate, scientific and pseudoscientific claims in advertising. Since advertising is used to sell products, the discourse of scientifically framed claims is being used to persuade consumers of the benefits of these products. In the case of functional foods and cosmetics, such statements are deployed to promote the health benefits and effectiveness of their products. This exploratory study examines the views of British consumers about the scientific and pseudoscientific claims made in advertisements for foods, with particular reference to functional foods, and cosmetics. The participants in the study all worked in scientific environments, though they were not all scientists. The study found that scientific arguments that were congruent with existing health knowledge tended to be accepted while pseudoscientific knowledge was regarded skeptically and concerns were raised over the accuracy and believability of the pseudoscientific claims. It appears that scientific awareness may play a part in consumers' ability to critically examine scientifically and pseudoscientifically based advertising claims.

Bathgate, Meghan; Crowell, Amanda; Schunn, Christian; Cannady, Mac; Dorph, Rena

2015-07-01

Engaging in science as an argumentative practice can promote students' critical thinking, reflection, and evaluation of evidence. However, many do not approach science in this way. Furthermore, the presumed confrontational nature of argumentation may run against cultural norms particularly during the sensitive time of early adolescence. This paper explores whether middle-school students' ability to engage in critical components of argumentation in science impacts science classroom learning. It also examines whether students' willingness to do so attenuates or moderates that benefit. In other words, does one need to be both willing and able to engage critically with the discursive nature of science to receive benefits to learning? This study of middle-school students participating in four months of inquiry science shows a positive impact of argumentative sensemaking ability on learning, as well as instances of a moderating effect of one's willingness to engage in argumentative discourse. Possible mechanisms and the potential impacts to educational practices are discussed.

The eXtreme Science Identity Management (XSIM1) research project: collected and analyzed real world data on virtual organization (VO) identity management (IdM) representing the last 15+ years of collaborative DOE science; constructed a descriptive VO IdM model based on that data; used the model and existing trends to project the direction for IdM in the 2020 timeframe; and provided guidance to scientific collaborations and resource providers that are implementing or seeking to improve IdM functionality. XSIM conducted over 20 semi­structured interviews of representatives from scientific collaborations and resource providers, both in the US and Europe; the interviewees supported diverse set ofmore » scientific collaborations and disciplines. We developed a definition of “trust,” a key concept in IdM, to understand how varying trust models affect where IdM functions are performed. The model identifies how key IdM data elements are utilized in collaborative scientific workflows, and it has the flexibility to describe past, present and future trust relationships and IdM implementations. During the funding period, we gave more than two dozen presentations to socialize our work, encourage feedback, and improve the model; we also published four refereed papers. Additionally, we developed, presented, and received favorable feedback on three white papers providing practical advice to collaborations and/or resource providers.« less

Science Partnerships Enabling Rapid Response: Designing a Strategy for Improving Scientific Collaboration during Crisis Response

NASA Astrophysics Data System (ADS)

Mease, L.; Gibbs, T.; Adiseshan, T.

2014-12-01

The 2010 Deepwater Horizon disaster required unprecedented engagement and collaboration with scientists from multiple disciplines across government, academia, and industry. Although this spurred the rapid advancement of valuable new scientific knowledge and tools, it also exposed weaknesses in the system of information dissemination and exchange among the scientists from those three sectors. Limited government communication with the broader scientific community complicated the rapid mobilization of the scientific community to assist with spill response, evaluation of impact, and public perceptions of the crisis. The lessons and new laws produced from prior spills such as Exxon Valdez were helpful, but ultimately did not lead to the actions necessary to prepare a suitable infrastructure that would support collaboration with non-governmental scientists. As oil demand pushes drilling into increasingly extreme environments, addressing the challenge of effective, science-based disaster response is an imperative. Our study employs a user-centered design process to 1) understand the obstacles to and opportunity spaces for effective scientific collaboration during environmental crises such as large oil spills, 2) identify possible tools and strategies to enable rapid information exchange between government responders and non-governmental scientists from multiple relevant disciplines, and 3) build a network of key influencers to secure sufficient buy-in for scaled implementation of appropriate tools and strategies. Our methods include user ethnography, complex system mapping, individual and system behavioral analysis, and large-scale system design to identify and prototype a solution to this crisis collaboration challenge. In this talk, we will present out insights gleaned from existing analogs of successful scientific collaboration during crises and our initial findings from the 60 targeted interviews we conducted that highlight key collaboration challenges that government agencies, academic research institutions, and industry scientists face during oil spill crises. We will also present a synthesis of leverage points in the system that may amplify the impact of an improved collaboration strategy among scientific stakeholders.

Network Effects on Scientific Collaborations

Uddin, Shahadat; Hossain, Liaquat; Rasmussen, Kim

2013-01-01

Background The analysis of co-authorship network aims at exploring the impact of network structure on the outcome of scientific collaborations and research publications. However, little is known about what network properties are associated with authors who have increased number of joint publications and are being cited highly. Methodology/Principal Findings Measures of social network analysis, for example network centrality and tie strength, have been utilized extensively in current co-authorship literature to explore different behavioural patterns of co-authorship networks. Using three SNA measures (i.e., degree centrality, closeness centrality and betweenness centrality), we explore scientific collaboration networks to understand factors influencing performance (i.e., citation count) and formation (tie strength between authors) of such networks. A citation count is the number of times an article is cited by other articles. We use co-authorship dataset of the research field of ‘steel structure’ for the year 2005 to 2009. To measure the strength of scientific collaboration between two authors, we consider the number of articles co-authored by them. In this study, we examine how citation count of a scientific publication is influenced by different centrality measures of its co-author(s) in a co-authorship network. We further analyze the impact of the network positions of authors on the strength of their scientific collaborations. We use both correlation and regression methods for data analysis leading to statistical validation. We identify that citation count of a research article is positively correlated with the degree centrality and betweenness centrality values of its co-author(s). Also, we reveal that degree centrality and betweenness centrality values of authors in a co-authorship network are positively correlated with the strength of their scientific collaborations. Conclusions/Significance Authors’ network positions in co-authorship networks influence the performance (i.e., citation count) and formation (i.e., tie strength) of scientific collaborations.

The Relationships Between Modelling and Argumentation from the Perspective of the Model of Modelling Diagram

NASA Astrophysics Data System (ADS)

Cardoso Mendonça, Paula Cristina; Justi, Rosária

2013-09-01

Some studies related to the nature of scientific knowledge demonstrate that modelling is an inherently argumentative process. This study aims at discussing the relationship between modelling and argumentation by analysing data collected during the modelling-based teaching of ionic bonding and intermolecular interactions. The teaching activities were planned from the transposition of the main modelling stages that constitute the 'Model of Modelling Diagram' so that students could experience each of such stages. All the lessons were video recorded and their transcriptions supported the elaboration of case studies for each group of students. From the analysis of the case studies, we identified argumentative situations when students performed all of the modelling stages. Our data show that the argumentative situations were related to sense making, articulating and persuasion purposes, and were closely related to the generation of explanations in the modelling processes. They also show that representations are important resources for argumentation. Our results are consistent with some of those already reported in the literature regarding the relationship between modelling and argumentation, but are also divergent when they show that argumentation is not only related to the model evaluation phase.

Scrutinizing Immutability: Research on Sexual Orientation and U.S. Legal Advocacy for Sexual Minorities.

PubMed

Diamond, Lisa M; Rosky, Clifford J

2016-01-01

We review scientific research and legal authorities to argue that the immutability of sexual orientation should no longer be invoked as a foundation for the rights of individuals with same-sex attractions and relationships (i.e., sexual minorities). On the basis of scientific research as well as U.S. legal rulings regarding lesbian, gay, and bisexual (LGB) rights, we make three claims: First, arguments based on the immutability of sexual orientation are unscientific, given what we now know from longitudinal, population-based studies of naturally occurring changes in the same-sex attractions of some individuals over time. Second, arguments based on the immutability of sexual orientation are unnecessary, in light of U.S. legal decisions in which courts have used grounds other than immutability to protect the rights of sexual minorities. Third, arguments about the immutability of sexual orientation are unjust, because they imply that same-sex attractions are inferior to other-sex attractions, and because they privilege sexual minorities who experience their sexuality as fixed over those who experience their sexuality as fluid. We conclude that the legal rights of individuals with same-sex attractions and relationships should not be framed as if they depend on a certain pattern of scientific findings regarding sexual orientation.

Geosciences Acting Out: Using Theatre to Understand Citizen Values and Concerns with Respect to Marcellus Gas Development

NASA Astrophysics Data System (ADS)

Orland, B.; Doan, W. J.; Russell, S. B.; Belser, A.

2014-12-01

Marcellus shale gas is being developed with unprecedented speed. The highly capitalized energy industry has influenced major changes in the regulatory framework at federal and state levels and entered into mineral lease agreements 100-fold bigger that previously seen in Northern Pennsylvania. At the same time, the technical and scientific issues at play from geology and hydrology through ecology and sociology effectively block local citizens from fully understanding and participating in decision-making about their own futures. The Marcellus Community-Based Performance Program engages adult residents, landowners, and local decision makers in knowledge-generating performances made collectively with those most impacted by shale gas development. Unlike traditional proscenium stage theatre, community-based performance is a collaborative means for exploring a collectively significant issue or circumstance. The choice to use a community-based theatre method, which engages the spectators in the performance itself as a way of making meaning, was based on the following goals to achieve good debate; to engage community participants in discussion through the exchange of ideas, argument and counter-argument, in an effort to further the education of all; to facilitate the perspectives of citizens in communities where different responses to the risk issues exist because of local economies and legacies with resource extraction. The plays and performances, developed around the broad theme of Living with Risk and Uncertainty, use existing research, reports, newspaper articles, and interviews to present the range of perceptions, facts, and issues surrounding the environmental risks associated with natural gas drilling and focused on developing scientific understanding. Performances have been assessed by seeking direct feedback from participants through pre-performance surveys, post-performance dialogues (talk-backs), and exit interviews. Participants have reported the highest levels of interest in performances related to the economy, health impacts of drilling, environmental impacts, and in learning from what other people have to say.

Micropublications: a semantic model for claims, evidence, arguments and annotations in biomedical communications

PubMed Central

2014-01-01

Background Scientific publications are documentary representations of defeasible arguments, supported by data and repeatable methods. They are the essential mediating artifacts in the ecosystem of scientific communications. The institutional “goal” of science is publishing results. The linear document publication format, dating from 1665, has survived transition to the Web. Intractable publication volumes; the difficulty of verifying evidence; and observed problems in evidence and citation chains suggest a need for a web-friendly and machine-tractable model of scientific publications. This model should support: digital summarization, evidence examination, challenge, verification and remix, and incremental adoption. Such a model must be capable of expressing a broad spectrum of representational complexity, ranging from minimal to maximal forms. Results The micropublications semantic model of scientific argument and evidence provides these features. Micropublications support natural language statements; data; methods and materials specifications; discussion and commentary; challenge and disagreement; as well as allowing many kinds of statement formalization. The minimal form of a micropublication is a statement with its attribution. The maximal form is a statement with its complete supporting argument, consisting of all relevant evidence, interpretations, discussion and challenges brought forward in support of or opposition to it. Micropublications may be formalized and serialized in multiple ways, including in RDF. They may be added to publications as stand-off metadata. An OWL 2 vocabulary for micropublications is available at http://purl.org/mp. A discussion of this vocabulary along with RDF examples from the case studies, appears as OWL Vocabulary and RDF Examples in Additional file 1. Conclusion Micropublications, because they model evidence and allow qualified, nuanced assertions, can play essential roles in the scientific communications ecosystem in places where simpler, formalized and purely statement-based models, such as the nanopublications model, will not be sufficient. At the same time they will add significant value to, and are intentionally compatible with, statement-based formalizations. We suggest that micropublications, generated by useful software tools supporting such activities as writing, editing, reviewing, and discussion, will be of great value in improving the quality and tractability of biomedical communications.

The coexistence of alternative and scientific conceptions in physics

NASA Astrophysics Data System (ADS)

Ozdemir, Omer F.

The purpose of this study was to inquire about the simultaneous coexistence of alternative and scientific conceptions in the domain of physics. This study was particularly motivated by several arguments put forward in opposition to the Conceptual Change Model. In the simplest form, these arguments state that people construct different domains of knowledge and different modes of perception in different situations. Therefore, holding different conceptualizations is unavoidable and expecting a replacement in an individual's conceptual structure is not plausible in terms of instructional practices. The following research questions were generated to inquire about this argument: (1) Do individuals keep their alternative conceptions after they have acquired scientific conceptions? (2) Assuming that individuals who acquired scientific conceptions also have alternative conceptions, how are these different conceptions nested in their conceptual structure? (3) What kind of knowledge, skills, and reasoning are necessary to transfer scientific principles instead of alternative ones in the construction of a valid model? Analysis of the data collected from the non-physics group indicated that the nature of alternative conceptions is framed by two types of reasoning: reasoning by mental simulation and semiformal reasoning. Analysis of the data collected from the physics group revealed that mental images or scenes feeding reasoning by mental simulation had not disappeared after the acquisition of scientific conceptions. The analysis of data also provided enough evidence to conclude that alternative principles feeding semiformal reasoning have not necessarily disappeared after the acquisition of scientific conceptions. However, in regard to semiformal reasoning, compartmentalization was not as clear as the case demonstrated in reasoning by mental simulation; instead semiformal and scientific reasoning are intertwined in a way that the components of semiformal reasoning can easily take their place among the components of scientific reasoning. In spite of the fact that the coexistence of multiple conceptions might obstruct the transfer of scientific conceptions in problem-solving situations, several factors stimulating the use of scientific conceptions were noticed explicitly. These factors were categorized as follows: (a) the level of individuals' domain specific knowledge in the corresponding field, (b) the level of individuals' knowledge about the process of science (how science generates its knowledge claims), (c) the level of individuals' awareness of different types of reasoning and conceptions, and (d) the context in which the problem is situated.

`Does it answer the question or is it French fries?': an exploration of language supports for scientific argumentation

NASA Astrophysics Data System (ADS)

González-Howard, María; McNeill, Katherine L.; Marco-Bujosa, Lisa M.; Proctor, C. Patrick

2017-03-01

Reform initiatives around the world are reconceptualising science education by stressing student engagement in science practices. Yet, science practices are language-intensive, requiring students to have strong receptive and productive language proficiencies. It is critical to address these rigorous language demands to ensure equitable learning opportunities for all students, including English language learners (ELLs). Little research has examined how to specifically support ELL students' engagement in science practices, such as argumentation. Using case-study methodology, we examined one middle school science teacher's instructional strategies as she taught an argumentation-focused curriculum in a self-contained ELL classroom. Findings revealed that three trends characterized the teacher's language supports for the structural and dialogic components of argumentation: (1) more language supports focused on argument structure, (2) dialogic interactions were most often facilitated by productive language supports, and (3) some language supports offered a rationale for argumentation. Findings suggest a need to identify and develop supports for the dialogic aspects of argumentation. Furthermore, engaging students in argumentation through productive language functions could be leveraged to support dialogic interactions. Lastly, our work points to the need for language supports that make the rationale for argumentation explicit since such transparency could further increase access for all students.

The paradigm that always was: Scientific discourse in Young-Earth Creationist textbooks

NASA Astrophysics Data System (ADS)

Maynard, Travis

Bob Jones University Press (BJU Press) is a publishing house owned by the Greenville, South Carolina university of the same name. Fulfilling Bob Jones' mission beyond the college classroom, BJU Press prints a full K-12 educational program that spans all subjects and meets national core content standards. These materials are nationally circulated in homeschooling environments and conservative Christian private schools, a growing portion of America's educational landscape: according to a Department of Education 2009 report, enrollment in these schools represented 885,000 students. Research in rhetoric facilitates our understanding of various discourse communities, especially those that appropriate the discourse of a separate community to forward an argument that runs counter to the purposes of the original community. An interesting example of this rhetorical strategy is BJU Press' educational philosophy called Biblical Integration, in which teachers are invoked to "call into question the secular assumptions of each subject and then encourage the student to rebuild the discipline from biblical presuppositions." Using this technique, teachers using BJU Press materials attempt to shape students' ideologies by teaching a literal reading of the Bible dictating a 6,000-year-old Earth. The most interesting subject area in which BJU Press deploys Biblical Integration is the natural sciences, wherein to achieve this goal, textbook authors must make two rhetorical moves: first, re-frame a biblical ideology as being equally scientific to its secular counterparts; and, second, argue for the superiority of a science based in the Bible. This thesis analyzes a science textbook produced by BJU Press, exploring how the authors meet these exigencies. Specifically, I argue that the authors of the eighth grade title Earth Science both adopt and adapt the discourse of science in order to validate Evangelical Christian Science as being legitimately engaged in scientific endeavors. Within the context of natural sciences, Biblical Integration is particularly compelling: in formulating an alternative view of science and arguing for its superiority over secular science, the authors at BJU Press are implicitly employing the discourse of Kuhnian scientific revolution, adding a layer of scientific credibility to their efforts by mimicking the historical progress of the sciences. In adopting a Kuhnian approach, the authors craft a hybrid discourse that blends science with scripture, working against the secular status quo of the sciences. Accordingly, to analyze this hybrid discourse, this thesis draws upon work within the rhetoric of science directly influenced by Thomas Kuhn. This analysis is conducted via two case studies. The first focuses on the textbook's introductory chapter, highlighting how the chapter appropriates the epistemological practices of scientific research by presenting an overarching argument that forwards a threefold purpose: (1) establishing the purpose of Christian Science; (2) highlighting the inherently ideological nature of scientific epistemology; and (3) providing a dualistic definition that polarizes Christian and secular science. By emphasizing the ideological nature of science, the authors of this textbook create a rhetorical space in which they can articulate their alternative view of science as being theoretically valid. The second case study analyzes a discipline-specific application of Christian Science: two textbook chapters that focus on geology. When the textbook attempts to operationalize Christian Science, this view falls short of the standards of science due to Evangelical faith in the infallibility of scripture. Despite this shortcoming, these two chapters still employ strategies indicative of Kuhnian paradigmatic arguments: highlighting fundamental anomalies in scientific consensus and utilizing arguments from familiarity to gain audiences' tentative acceptance. In using these argumentative strategies, the textbook authors mimic scientific argument, but do not fully meet the criteria of science.

Reflections on scientific collaboration between basic researchers and clinicians.

PubMed

Muia, J; Casari, C

2016-10-01

Early career researchers face uncertainties with respect to their job prospects due to dwindling job markets, decreased availability of funding and undefined career paths. As basic researchers and clinicians tend to have different approaches to scientific problems, there are many advantages from successful collaborations between them. Here, we discuss how collaborations between basic and clinical scientists should be promoted early in their careers. To achieve this, researchers, both basic and clinical, must be proactive during their training and early stages of their careers. Mentors can further augment collaborative links in many ways. We suggest that universities and institutions might reassess their involvement in promoting collaborations between basic and clinical researchers. We hope that this paper will serve as a reminder of the importance of such collaborations, and provide the opportunity for all members of the scientific community to reflect on and ameliorate their own contributions. © 2016 International Society on Thrombosis and Haemostasis.

The PACA Project : Pro-Am Collaborative Astronomy

Yanamandra-Fisher, P. A.

2014-04-01

The Pro-Am Collaborative Astronomy (PACA) project is the next stage of evolution of the paradigm developed for the observational campaign of C/2012 S1 or C/ISON. Four different phases of collaboration are identified, and illustrate the integration of scientific investigations with amateur astronomer community via observations, and models; and the rapid dissemination of the results via a multitude of social media for rapid global access. The success of the paradigm shift in scientific research is now implemented in other comet observing campaigns. Both communities (scientific and amateur astronomers) benefit from these collective, collaborative partnerships; while outreach is the instantaneous deliverable that provides both a framework for future data analyses and the dissemination of the results. While PACA identifies a collaborative approach to pro-am collaborations, given the volume of data generated for each campaign, new ways of rapid data analysis, mining access and storage are needed.

Balancing the pros and cons of GMOs: socio-scientific argumentation in pre-service teacher education

NASA Astrophysics Data System (ADS)

Cinici, Ayhan

2016-07-01

This study investigates the role of the discursive process in the act of scientific knowledge building. Specifically, it links scientific knowledge building to risk perception of Genetically Modified Organisms (GMOs). To this end, this study designed and implemented a three-stage argumentation programme giving pre-service teachers (PSTs) the opportunity to consider, discuss and construct shared decisions about GMOs. The study involved 101 third-year PSTs from two different classes, randomly divided into control and experimental groups. The study utilised both quantitative and qualitative methods. During the quantitative phase, researchers administered a pre- and post-intervention scale to measure both groups' risk perception of GMOs. During the qualitative phase, data were collected from the experimental group alone through individual and group reports and an open-ended questionnaire. T-test results showed a statistically significant difference between the experimental and control groups' risk perception of GMOs. Qualitative analysis also revealed differences, for example, in PSTs' weighing of the pros and cons of scientific research demonstrating positive results of GMOs. In addition, PSTs' acceptance of GMOs increased. Consequently, this study suggests that developing familiarity with scientific enterprise may play an effective role in adopting a scientific perspective as well as a more balanced risk perception of GMOs.

Trajectories of collaborative scientific conceptual change: Middle school students learning about ecosystems in a CSCL environment

The dissertation aims to achieve two goals. First, it attempts to establish a new theoretical framework---the collaborative scientific conceptual change model, which explicitly attends to social factor and epistemic practices of science, to understand conceptual change. Second, it report the findings of a classroom study to investigate how to apply this theoretical framework to examine the trajectories of collaborative scientific conceptual change in a CSCL environment and provide pedagogical implications. Two simulations were designed to help students make connections between the macroscopic substances and the aperceptual microscopic entities and underlying processes. The reported study was focused on analyzing the aggregated data from all participants and the video and audio data from twenty focal groups' collaborative activities and the process of their conceptual development in two classroom settings. Mixed quantitative and qualitative analyses were applied to analyze the video/audio data. The results found that, overall participants showed significant improvements from pretest to posttest on system understanding. Group and teacher effect as well as group variability were detected in both students' posttest performance and their collaborative activities, and variability emerged in group interaction. Multiple data analyses found that attributes of collaborative discourse and epistemic practices made a difference in student learning. Generating warranted claims in discourse as well as the predicting, coordinating theory-evidence, and modifying knowledge in epistemic practices had an impact on student's conceptual understanding. However, modifying knowledge was found negatively related to students' learning effect. The case studies show how groups differed in using the computer tools as a medium to conduct collaborative discourse and epistemic practices. Only with certain combination of discourse features and epistemic practices can the group interaction lead to successful convergent understanding. The results of the study imply that the collaborative scientific conceptual change model is an effective framework to study conceptual change and the simulation environment may mediate the development of successful collaborative interactions (including collaborative discourse and epistemic practices) that lead to collaborative scientific conceptual change.

Improving the ability of young people to construct arguments about controversial science topics is a desired outcome of science education. The purpose of this research was to evaluate the impact of an argumentation intervention on the socioscientific issue of climate change with Year 10 students in a disadvantaged Australian school. After participation in a professional development workshop on climate change science, socioscientific issues and argumentation, an early career teacher explicitly taught argumentation over four non-consecutive lessons as part of a 4 week (16 lesson) topic on Earth science. Thirty students completed a pre- and post-test questionnaire to determine their understanding of climate change science and their ability to construct an argument about a climate change socioscientific issue. Students' understanding of climate change improved significantly (p < .001) with a large effect size. There was also a significant increase (p < .05) in the number of categories provided in written arguments about a climate change issue. Qualitative data, comprising classroom observation field notes, lesson transcripts, work samples, and teacher and student interviews, were analysed for the extent to which the students' argumentation skills improved. At the end of the intervention, students became aware of the need to justify their decisions with scientific evidence. It is concluded that introducing argumentation about climate change socioscientific issues to students in a disadvantaged school can improve their argumentation skills.

The delphic oracle and the ethylene-intoxication hypothesis.

PubMed

Foster, J; Lehoux, D

2007-01-01

An interdisciplinary team of scientists--including an archeologist, a geologist, a chemist, and a toxicologist--has argued that ethylene intoxication was the probable cause of the High Priestess of Delphi's divinatory (mantic) trances. The claim that the High Priestess of Delphi entered a mantic state because of ethylene intoxication enjoyed widespread reception in specialist academic journals, science magazines, and newspapers. This article uses a similar interdisciplinary approach to show that this hypothesis is implausible since it is based on problematic scientific and textual evidence, as well as a fallacious argument. The main issue raised by this counterargument is not that a particular scientific hypothesis or conjecture turned out to be false. (This is expected in scientific investigation.) Rather, the main issue is that it was a positivist disposition that originally led readers to associate the evidence presented in such a way that it seemed to point to the conclusion, even when the evidence did not support the conclusion. We conclude by observing that positivist dispositions can lead to the acceptance of claims because they have a scientific form, not because they are grounded in robust evidence and sound argument.

Today's conservation challenges are complex. Solving these challenges often requires scientific collaborations that extend beyond the scope, expertise, and capacity of any single agency, organization, or institution. Conservation efforts can benefit from interdisciplinary collaboration, scientific and technological innovations, and the leveraging of capacity and resources among partners. Here we explore a series of case studies demonstrating how collaborative scientific partnerships are furthering the mission of the U.S. Fish and Wildlife Service, including: 1) contaminants of emerging concern in the Great Lakes Basin, 2) Poweshiek skipperling conservation, 3) using technology to improve population survey methods for bats and monarch butterfly, and 4) Big River restoration in the Southeast Missouri lead mining district. These case studies illustrate how strategic and effective scientific collaboration is a multi-stage process that requires investment of time and resources by all participants. Early coordination and communication is crucial to aligning planned work with scientific and decision-making needs. Collaborations between USFWS and external scientists can be mutually beneficial by supporting the agency mission while also providing an avenue for innovative research to be directly applied in conservation decisions and management actions.

International collaboration is increasingly used in biomedical research. To describe the characteristics of scientific production in Latin America and the main international collaboration networks for the period 2000 to 2009. Search for papers generated in Latin American countries in the Clinical Medicine database of ISI Web of Knowledge v.4.10 - Current Contents Connect. The country of origin of the corresponding author was considered the producing country of the paper. International collaboration was analyzed calculating the number of countries that contributed to the generation of a particular paper. Collaboration networks were graphed to determine the centrality of each network. Twelve Latin American countries participated in the production of 253,362 papers. The corresponding author was South American in 79% of these papers. Sixteen percent of papers were on clinical medicine and 36% of these were carried out in collaboration. Brazil had the highest production (22,442 papers) and the lower percentage of international collaboration (31%). North America accounts for 63% of collaborating countries. Only 8% of collaboration is between South American countries. Brazil has the highest tendency to collaborate with other South American countries. Brazil is the South American country with the highest scientific production and indicators of centrality in South America. The most common collaboration networks are with North American countries.

Termination of the leprosy isolation policy in the US and Japan : Science, policy changes, and the garbage can model

Sato, Hajime; Frantz, Janet E

2005-01-01

Background In both the US and Japan, the patient isolation policy for leprosy /Hansen's disease (HD) was preserved along with the isolation facilities, long after it had been proven to be scientifically unnecessary. This delayed policy termination caused a deprivation of civil liberties of the involuntarily confined patients, the fostering of social stigmas attached to the disease, and an inefficient use of health resources. This article seeks to elucidate the political process which hindered timely policy changes congruent with scientific advances. Methods Examination of historical materials, supplemented by personal interviews. The role that science played in the process of policy making was scrutinized with particular reference to the Garbage Can model. Results From the vantage of history, science remained instrumental in all period in the sense that it was not the primary objective for which policy change was discussed or intended, nor was it the principal driving force for policy change. When the argument arose, scientific arguments were employed to justify the patient isolation policy. However, in the early post-WWII period, issues were foregrounded and agendas were set as the inadvertent result of administrative reforms. Subsequently, scientific developments were more or less ignored due to concern about adverse policy outcomes. Finally, in the 1980s and 1990s, scientific arguments were used instrumentally to argue against isolation and for the termination of residential care. Conclusion Contrary to public expectations, health policy is not always rational and scientifically justified. In the process of policy making, the role of science can be limited and instrumental. Policy change may require the opening of policy windows, as a result of convergence of the problem, policy, and political streams, by effective exercise of leadership. Scientists and policymakers should be attentive enough to the political context of policies. PMID:15771781

Dealing with conflicts on knowledge in tutorial groups.

2013-05-01

The aim of our study was to gain understanding of different types of conflicts on knowledge in the discussions of problem-based learning tutorial groups, and how such conflicts are dealt with. We examined first-year medical and dental students' (N = 33) conflicts on knowledge in four videotaped reporting phase tutorials. A coding scheme was created for analysing verbatim transcripts of 43 conflict episodes in order to find out whether the conflict episodes were about factual or conceptual knowledge and how the students elaborated the knowledge. Conflict episodes were relatively rare (taking up 7.6 % of the time) in the videotaped groups. Conflict episodes were more frequently about factual knowledge (58 %) than conceptual knowledge (42 %), but conflicts on conceptual knowledge lasted longer and were more often elaborated. Elaboration was, however, more frequently done individually than collaboratively. Conflict episodes were generally fairly short (mean duration 28 s). This was due to a lack of thorough argumentation and collaborative elaboration of conflicting ideas. The results suggest that students' skills to bring out differences in each other's conceptual thinking, the depth of argumentation and the use of questions that elicit elaboration need to be improved. Tutors' skills to facilitate the collaborative resolving of conflicts on knowledge call for further study.

In HEP, scientific research is performed by large collaborations of organizations and individuals. The logbook of a scientific collaboration is an important part of the collaboration record. Often it contains experimental data. At Fermi National Accelerator Laboratory (FNAL), we developed an Electronic Collaboration Logbook (ECL) application, which is used by about 20 different collaborations, experiments and groups at FNAL. The ECL is the latest iteration of the project formerly known as the Control Room Logbook (CRL). We have been working on mobile (IOS and Android) clients for the ECL. We will present the history, current status and future plans of the project, as well as design, implementation and support solutions made by the project.

Visualization analysis of author collaborations in schizophrenia research.

Schizophrenia is a serious mental illness that levies a heavy medical toll and cost burden throughout the world. Scientific collaborations are necessary for progress in psychiatric research. However, there have been few publications on scientific collaborations in schizophrenia. The aim of this study was to investigate the extent of author collaborations in schizophrenia research. This study used 58,107 records on schizophrenia from 2003 to 2012 which were downloaded from Science Citation Index Expanded (SCI Expanded) via Web of Science. CiteSpace III, an information visualization and analysis software, was used to make a visual analysis. Collaborative author networks within the field of schizophrenia were determined using published documents. We found that external author collaboration networks were more scattered while potential author collaboration networks were more compact. Results from hierarchical clustering analysis showed that the main collaborative field was genetic research in schizophrenia. Based on the results, authors belonging to different institutions and in different countries should be encouraged to collaborate in schizophrenia research. This will help researchers focus their studies on key issues, and allow each other to offer reasonable suggestions for making polices and providing scientific evidence to effectively diagnose, prevent, and cure schizophrenia.

Designing a CTSA‐Based Social Network Intervention to Foster Cross‐Disciplinary Team Science

2015-01-01

Abstract This paper explores the application of network intervention strategies to the problem of assembling cross‐disciplinary scientific teams in academic institutions. In a project supported by the University of Florida (UF) Clinical and Translational Science Institute, we used VIVO, a semantic‐web research networking system, to extract the social network of scientific collaborations on publications and awarded grants across all UF colleges and departments. Drawing on the notion of network interventions, we designed an alteration program to add specific edges to the collaboration network, that is, to create specific collaborations between previously unconnected investigators. The missing collaborative links were identified by a number of network criteria to enhance desirable structural properties of individual positions or the network as a whole. We subsequently implemented an online survey (N = 103) that introduced the potential collaborators to each other through their VIVO profiles, and investigated their attitudes toward starting a project together. We discuss the design of the intervention program, the network criteria adopted, and preliminary survey results. The results provide insight into the feasibility of intervention programs on scientific collaboration networks, as well as suggestions on the implementation of such programs to assemble cross‐disciplinary scientific teams in CTSA institutions.

Normative ethics does not need a foundation: it needs more science.

Quintelier, Katinka; Van Speybroeck, Linda; Braeckman, Johan

2011-03-01

The impact of science on ethics forms since long the subject of intense debate. Although there is a growing consensus that science can describe morality and explain its evolutionary origins, there is less consensus about the ability of science to provide input to the normative domain of ethics. Whereas defenders of a scientific normative ethics appeal to naturalism, its critics either see the naturalistic fallacy committed or argue that the relevance of science to normative ethics remains undemonstrated. In this paper, we argue that current scientific normative ethicists commit no fallacy, that criticisms of scientific ethics contradict each other, and that scientific insights are relevant to normative inquiries by informing ethics about the options open to the ethical debate. Moreover, when conceiving normative ethics as being a nonfoundational ethics, science can be used to evaluate every possible norm. This stands in contrast to foundational ethics in which some norms remain beyond scientific inquiry. Finally, we state that a difference in conception of normative ethics underlies the disagreement between proponents and opponents of a scientific ethics. Our argument is based on and preceded by a reconsideration of the notions naturalistic fallacy and foundational ethics. This argument differs from previous work in scientific ethics: whereas before the philosophical project of naturalizing the normative has been stressed, here we focus on concrete consequences of biological findings for normative decisions or on the day-to-day normative relevance of these scientific insights.

Using Computer-Assisted Argumentation Mapping to develop effective argumentation skills in high school advanced placement physics

NASA Astrophysics Data System (ADS)

Heglund, Brian

Educators recognize the importance of reasoning ability for development of critical thinking skills, conceptual change, metacognition, and participation in 21st century society. There is a recognized need for students to improve their skills of argumentation, however, argumentation is not explicitly taught outside logic and philosophy---subjects that are not part of the K-12 curriculum. One potential way of supporting the development of argumentation skills in the K-12 context is through incorporating Computer-Assisted Argument Mapping to evaluate arguments. This quasi-experimental study tested the effects of such argument mapping software and was informed by the following two research questions: 1. To what extent does the collaborative use of Computer-Assisted Argumentation Mapping to evaluate competing theories influence the critical thinking skill of argument evaluation, metacognitive awareness, and conceptual knowledge acquisition in high school Advanced Placement physics, compared to the more traditional method of text tables that does not employ Computer-Assisted Argumentation Mapping? 2. What are the student perceptions of the pros and cons of argument evaluation in the high school Advanced Placement physics environment? This study examined changes in critical thinking skills, including argumentation evaluation skills, as well as metacognitive awareness and conceptual knowledge, in two groups: a treatment group using Computer-Assisted Argumentation Mapping to evaluate physics arguments, and a comparison group using text tables to evaluate physics arguments. Quantitative and qualitative methods for collecting and analyzing data were used to answer the research questions. Quantitative data indicated no significant difference between the experimental groups, and qualitative data suggested students perceived pros and cons of argument evaluation in the high school Advanced Placement physics environment, such as self-reported sense of improvement in argument evaluation and low perceived value of the learning task, respectively. The discussion presents implications for practice and research, such as introducing motivation scaffolds to support appreciation of task value, and addressing major differences between the design of this study and similar published studies, respectively. This work provides contributions in that it tested the effect of Computer-Assisted Argumentation Mapping on the critical thinking skills of twelfth-grade students within the context of evaluating physics arguments, a previously unexplored age group and domain.

Scientific cooperation is essential for the advance of biomedical research. Scientists set up informal groups to work together on common issues, who are the main units in the research funding system. Bibliometric and Social Network Analysis methods allow informal groups in scientific papers to be identified and characterised. The objective of the study is to identify research groups in Archivos de Bronconeumología between 2003 and 2007 period with the aim of characterizing their scientific collaboration patterns and research areas. Co-authorships, institutional collaboration relationships and the main research areas of papers published in Archivos de Bronconeumología have been identified. Co-authorship networks and institutional collaboration networks have been constructed by using Pajek software tool. A total of 41 research groups involving 171 investigators have been identified. The Collaboration Index for articles was 5.59 and the Transcience Index was 73.11%. There was institutional collaboration in 60.33% of papers. The collaboration between institutions of the same region prevails (41.03%), followed by collaborations between departments, services or units of the same institution (39.74%), inter-regional collaboration (14,97%) and international collaboration (6.83%). A total of 83.03% of articles were cited. The main research areas covered by groups were chronic obstructive pulmonary disease, asthma, lung neoplasm, bronchogenic carcinoma, smoking and pulmonary embolism. The scientific production of a large number of Respiratory System Spanish research groups is published in Archivos de Bronconeumología. A notable collaboration and citation rate has been observed. Nevertheless, it is still essential to encourage inter-regional and international collaboration. Copyright 2009 SEPAR. Published by Elsevier Espana. All rights reserved.

Exploring Science Teachers' Argumentation and Personal Epistemology About Global Climate Change

NASA Astrophysics Data System (ADS)

Liu, Shiyu; Roehrig, Gillian

2017-06-01

This case study investigated the nature of in-service science teachers' argumentation and personal epistemology about global climate change during a 3-year professional development program on climate change education. Qualitative analysis of data from interviews and written assessments revealed that while these teachers grounded their arguments on climate issues in evidence, the evidence was often insufficient to justify their causal claims. Compared with generating arguments for their own views, teachers had more difficulties in constructing evidence-based arguments for alternative perspectives. Moreover, while these teachers shared some similarities in their epistemology about climate science, they varied in their beliefs about specific aspects such as scientists' expertise and the credibility of scientific evidence. Such similarities and distinctions were shown to relate to how teachers used evidence to justify claims in their arguments. The findings also suggested a mismatch between teachers' personal epistemology about science in general and climate science, which was revealed through their argumentation. This work helps to further the ongoing discussions in environmental education about what knowledge and skills teachers need in order to teach climate issues and prepare students for future decision making. It constitutes first steps to facilitate reasoning and argumentation in climate change education and provides important implications for future design of professional development programs.

Using History and Philosophy of Science to Promote Students' Argumentation

NASA Astrophysics Data System (ADS)

Archila, Pablo Antonio

2015-11-01

This article describes the effect of a teaching-learning sequence (TLS) based on the discovery of oxygen in promoting students' argumentation. It examines the written and oral arguments produced by 63 high school students (24 females and 39 males, 16-17 years old) in France during a complete TLS supervised by the same teacher. The data used in this analysis was derived from students' written responses, audio and video recordings, and written field notes. The first goal of this investigation was to provide evidence that an approach combining history and philosophy of science and argumentation could increase students' awareness of the relevance of experimentation and communication to scientific progress. The second goal was to assess the effectiveness of the TLS to engage students in argumentative classroom interactions (such as debates) relating to the discovery of oxygen at the end of the 18th century. The findings show that this historical case can be useful for promoting students' argumentation and is also appropriate for high school students. Future research should include students of other ages, other historical episodes and experiences in other parts of the world.

Understanding Students' Reasoning: Argumentation Schemes as an Interpretation Method in Science Education

NASA Astrophysics Data System (ADS)

Konstantinidou, Aikaterini; Macagno, Fabrizio

2013-05-01

The purpose of this paper is to investigate the argumentative structure of students' arguments using argumentation schemes as an instrument for reconstructing the missing premises underlying their reasoning. Building on the recent literature in science education, in order for an explanation to be persuasive and achieve a conceptual change it needs to proceed from the interlocutor's background knowledge to the analysis of the unknown or wrongly interpreted phenomena. Argumentation schemes represent the abstract forms of the most used and common forms of human reasoning, combining logical principles with semantic concepts. By identifying the argument structure it is possible to retrieve the missing premises and the crucial concepts and definition on which the conclusion is based. This method of analysis will be shown to provide the teacher with an instrument to improve his or her explanations by taking into consideration the students' intuitions and deep background knowledge on a specific issue. In this fashion the teacher can advance counterarguments or propose new perspectives on the subject matter in order to persuade the students to accept new scientific concepts.

By means of scientometric indicators, this study investigated the characteristics of scientific production and research collaboration involving zebrafish (Danio rerio) in Brazilian Science indexed by the Web of Science (WoS). Citation data were collected from the WoS and data regarding Impact Factor (IF) were gathered from journals in the Journal Citation Reports. Collaboration was evaluated according to coauthorship data, creating representative nets with VOSviewer. Zebrafish has attained remarkable importance as an experimental model organism in recent years and an increase in scientific production with zebrafish is observed in Brazil and around the world. The citation impact of the worldwide scientific production is superior when compared to the Brazilian scientific production. However, the citation impact of the Brazilian scientific production is consistently increasing. Brazil does not follow the international trends with regard to publication research fields. The state of Rio Grande do Sul has the greatest number of articles and the institution with the largest number of publications is Pontifícia Universidade Católica do Rio Grande do Sul. Journals' average IF is higher in Brazilian publications with international coauthorship, and around 90% of articles are collaborative. The Brazilian institutions presenting the greatest number of collaborations are Pontifícia Universidade Católica do Rio Grande do Sul, Universidade Federal do Rio Grande do Sul, Fundação Universidade Federal de Rio Grande, and Universidade de São Paulo. These data indicate that Brazilian research using zebrafish presents a growth in terms of number of publications, citation impact, and collaborative work.

The establishment of scientific collaborations with researchers abroad can be considered a good practice to make appropriate use of their knowledge and to increase the possibilities of them returning to their country. This paper analyses the collaboration between Spanish researchers abroad devoted to health sciences and national science institutions. We used the Fontes' approach to perform a study on this collaboration with Spanish researchers abroad. We measured the level of national and international cooperation, the opportunity provided by the host country to collaborate, the promotion of collaboration by national science institutions, and the types of collaboration. A total of 88 biomedical researchers out of the 268 Spanish scientists who filled up the survey participated in the study. Different data analyses were performed to study the variables selected to measure the scientific collaboration and profile of Spanish researchers abroad. There is a high level of cooperation between Spanish health science researchers abroad and international institutions, which contrasts with the small-scale collaboration with national institutions. Host countries facilitate this collaboration with national and international scientific institutions to a larger extent than the level of collaboration promotion carried out by Spanish institutions. The national collaboration with Spanish researchers abroad in the health sciences is limited. Thus, the practice of making appropriate use of the potential of their expertise should be promoted and the opportunities for Spanish health science researchers to return home should be improved.

A Blended Professional Development Program to Help a Teacher Learn to Provide One-to-One Scaffolding

Belland, Brian R.; Burdo, Ryan; Gu, Jiangyue

2015-04-01

Argumentation is central to instruction centered on socio-scientific issues (Sadler & Donnelly in International Journal of Science Education, 28(12), 1463-1488, 2006. doi: 10.1080/09500690600708717). Teachers can play a big role in helping students engage in argumentation and solve authentic scientific problems. To do so, they need to learn one-to-one scaffolding—dynamic support to help students accomplish tasks that they could not complete unaided. This study explores a middle school science teacher's provision of one-to-one scaffolding during a problem-based learning unit, in which students argued about how to optimize the water quality of their local river. The blended professional development program incorporated three 1.5-h seminars, one 8-h workshop, and 4 weeks of online education activities. Data sources were video of three small groups per period, and what students typed in response to prompts from computer-based argumentation scaffolds. Results indicated that the teacher provided one-to-one scaffolding on a par with inquiry-oriented teachers described in the literature.

Though the science on climate change is clear, those dismissive of current findings and future projections continue to influence the public sphere. This is never more problematic than in an educational setting, where a concern for fairness has driven the push for unscientific material to be used to balance the science. The introduction of the Next Generation Science Standards in many states across the country, which emphasizes the use of argumentation as a theme for engaging students in critical thinking, and the appeal of having students 'debate' politically controversial concepts such as climate change could unintentionally undermine the science by casting doubt and manufacturing 'controversy' where scientifically there is none. How can scientists help support teachers to use appropriate material for educating about climate change? Where is the line between supporting good science and activism? How can teachers separate the science from the politics without undermining its value in informing policy decisions? In this presentation, we will address how teachers can manage these challenges to engage students about politically and socially controversial topics while maintaining a clear, current and robust scientific basis for instruction.

Smoke-free policies are critical to global tobacco control, and prior research on media coverage of smoke-free policies primarily focused on the period when they were first innovated; however, the scientific basis for smoke-free policies has broadened, and how media coverage has changed, if at all, is unknown. The authors characterized the actors, arguments, and favorability of media coverage of smoke-free policies from 2006 to 2009, by content-analyzing 452 news stories in the 4 primary newspapers in South Carolina. Most media coverage was favorable (45%) or mixed (43%) toward smoke-free policies, and negative coverage decreased over time (B = -1.001, SE = 0.326; p = .008). The most prevalent argument concerned the harms of secondhand smoke (44%). A higher percentage of articles mentioned economic arguments against (26%) than for (17%) smoke-free policies (χ(2) = 10.89, p < .01, for the difference between 26% and 17%), and these percentages did not change over time. Advocates and media should improve communications to more effectively represent scientific evidence regarding the null or positive impact of smoke-free policies on businesses.

Cognitive and Social Structure of the Elite Collaboration Network of Astrophysics: A Case Study on Shifting Network Structures

Heidler, Richard

2011-01-01

Scientific collaboration can only be understood along the epistemic and cognitive grounding of scientific disciplines. New scientific discoveries in astrophysics led to a major restructuring of the elite network of astrophysics. To study the interplay of the epistemic grounding and the social network structure of a discipline, a mixed-methods…

One aim of inquiry activities in science education is to promote students' participation in the practices used to build scientific knowledge by providing opportunities to engage in scientific discourse. However, many factors influence the actual outcomes and effect on students' learning when using inquiry materials. In this study, discourse from…

Learning Science Content through Socio-Scientific Issues-Based Instruction: A Multi-Level Assessment Study

ERIC Educational Resources Information Center

Sadler, Troy D.; Romine, William L.; Topçu, Mustafa Sami

2016-01-01

Science educators have presented numerous conceptual and theoretical arguments in favor of teaching science through the exploration of socio-scientific issues (SSI). However, the empirical knowledge base regarding the extent to which SSI-based instruction supports student learning of science content is limited both in terms of the number of…

Dialogic Framing of Scientific Content for Conceptual and Epistemic Understanding

ERIC Educational Resources Information Center

Ford, Michael J.; Wargo, Brian M.

2012-01-01

This article draws on M. M. Bakhtin's (1981) notion of dialogism to articulate what it means to understand a scientific idea. In science, understanding an idea is both conceptual and epistemic and is exhibited by an ability to use it in explanation and argumentation. Some distillation of these activities implies that dialogic understanding of a…

The Research Potential of Educational Theory: On the Specific Characteristics of the Issues of Education

ERIC Educational Resources Information Center

Les, Tomasz

2017-01-01

In this article, I present the argument that educational theory has specific character, which distinguishes it from most scientific disciplines. It requires the application of not only strictly scientific methods, which essentially consist of descriptions and explanations, but also normative ones, which indicate how it is related to philosophy and…

This study examines the verbal interactions among a group of pre-service teachers as they engaged in scientific discussions in a medicinal chemistry course. These discussions were part of the course that encompassed an explicit instruction of scientific argumentation structures as well as an applied component, whereby the pre-service teachers…

Moral and Ethical Dimensions of Socioscientific Decision-Making as Integral Components of Scientific Literacy

ERIC Educational Resources Information Center

Sadler, Troy D.

2004-01-01

Science educators have appropriated many meanings for the phrase "scientific literacy" (Champagne & Lovitts, 1989). This paper advances an argument that in order to maintain the usefulness of such a malleable phrase, its users must explicitly address the context of its use. Based on the vision of science education articulated in standards…

Whose Science and Whose Religion? Reflections on the Relations between Scientific and Religious Worldviews

ERIC Educational Resources Information Center

Glennan, Stuart

2009-01-01

Arguments about the relationship between science and religion often proceed by identifying a set of essential characteristics of scientific and religious worldviews and arguing on the basis of these characteristics for claims about a relationship of conflict or compatibility between them. Such a strategy is doomed to failure because science, to…

How Historical Experiments Can Improve Scientific Knowledge and Science Education: The Cases of Boiling Water and Electrochemistry

ERIC Educational Resources Information Center

Chang, Hasok

2011-01-01

I advance some novel arguments for the use of historical experiments in science education. After distinguishing three different types of historical experiments and their general purposes, I define "complementary experiments", which can recover lost scientific knowledge and extend what has been recovered. Complementary experiments can help science…
