  1. School Science: A Questionable Construct?

    ERIC Educational Resources Information Center

    Jenkins, Edgar

    2007-01-01

    I explore the emergence of science and scientific method as political constructs in the 19th century and argue that the associated rhetoric continues to have significant consequences for contemporary school science education. It allows science to be promoted as a coherent curriculum component and fosters an untenable but enduring notion of a…

  5. Writing clinical scenarios for clinical science questions.

    PubMed

    Smith, Phil Em; Mucklow, John C

    2016-04-01

    Written knowledge assessments for physicians in training typically involve multiple-choice questions that use a clinical scenario in a single-best-answer format. The Royal College of Physicians Part 1 MRCP(UK) examination includes basic sciences themes that are challenging to assess through a clinical scenario. A realistic clinical setting based on everyday clinical practice and integral to the question is the clearest demonstration that the knowledge being assessed is clinically relevant. However, without special attention to detail, the scenario in a clinical science question can appear redundant or artificial. Reading unnecessary material frustrates candidates and threatens the reputation of the assessment. In this paper we discuss why a clinical scenario is important for basic science questions and offer advice on setting realistic and plausible clinical scenarios for such questions. PMID:27037383

    General education must develop in students an appreciation of the power of science, how it works, why it is an effective knowledge generation tool, and what it can deliver. Knowing what science has discovered is desirable but less important.

  7. Science Fiction and the Big Questions

    NASA Astrophysics Data System (ADS)

    O'Keefe, M.

    Advocates of space science promote investment in science education and the development of new technologies necessary for space travel. Success in these areas requires an increase of interest and support among the general public. What role can entertainment media play in inspiring the public ­ especially young people ­ to support the development of space science? Such inspiration is badly needed. Science education and funding in the United States are in a state of crisis. This bleak situation exists during a boom in the popularity of science-oriented television shows and science fiction movies. This paper draws on interviews with professionals in science, technology, engineering and mathematics (STEM) fields, as well as students interested in those fields. The interviewees were asked about their lifelong media-viewing habits. Analysis of these interviews, along with examples from popular culture, suggests that science fiction can be a valuable tool for space advocates. Specifically, the aspects of character, story, and special effects can provide viewers with inspiration and a sense of wonder regarding space science and the prospect of long-term human space exploration.

  8. The effects on interest, instruction, and achievement on the science question level of middle school students

    Cuccio Schirripa, Santine

    analyzed for main effects and interaction effects using general linear modeling procedures. The variable modeled was question level. There was one within subjects factor, science topic interest, and four between subjects factors: instruction, science achievement, mathematics achievement and reading achievement. The results, consistent with the hypotheses, indicate that students who received instruction in researchable questioning outperformed those students who were not instructed on a measure of science question level; when students were interested in a science topic their question level was significantly higher than when they were not interested; and students who were high achievers in mathematics, reading or science outperformed those students who were not high achievers on a measure of science question level.

  12. Doing Science and Asking Questions II: An Exercise That Generates Questions

    Hurt Middlecamp, Catherine; Nickel, Anne-Marie L.

    2005-08-01

    Given the importance of questions in science, it is critical that students learn to ask questions as well as learning to answer them. This paper describes a classroom exercise to help students better ask their own questions. It has been classroom-tested in multiple formats and has also been used for curriculum development workshops for faculty. This exercise in creating questions can be easily customized to suit different instructional contexts; some variations are outlined. More broadly, this paper also discusses the pedagogical significance of questioning, raising four salient points: (1) learners are more likely to have a personal interest in the questions they raise; (2) questions can serve as entry points for issues relating to ethnicity and gender; (3) questions give control to the person who asks them; and (4) questions can challenge existing structures, categories, and norms.

  13. Questioning behaviour in general practice: a pragmatic study.

    PubMed Central

    Barrie, A. R.; Ward, A. M.

    1997-01-01

    OBJECTIVE: To study the extent to which general practitioners' questioning behaviour in routine practice is likely to encourage the adoption of evidence based medicine. DESIGN: Self recording of questions by doctors during consultations immediately followed by semistructured interview. SETTING: Urban Australian general practice. SUBJECTS: Random sample of 27 general practitioners followed over a half day of consultations. MAIN OUTCOME MEASURES: Rate of recording of clinical questions about patients' care which doctors would like answered; frequency with which doctors found answers to their questions. RESULTS: Doctors asked a total of 85 clinical questions, at a rate of 2.4 for every 10 patients seen. They found satisfactory answers to 67 (79%) of these questions. Doctors who worked in small practices (of one or two doctors) had a significantly lower rate of questioning than did those in larger practices (1.6 questions per 10 patients v 3.0 patients, P = 0.049). No other factors were significantly related to rate of questioning. CONCLUSIONS: These results do not support the view that doctors routinely generate a large number of unanswered clinical questions. It may be necessary to promote questioning behaviour in routine practice if evidence based medicine and other forms of self directed learning are to be successfully introduced. PMID:9420495

  19. Power dynamics and questioning in elementary science lessons

    NASA Astrophysics Data System (ADS)

    Reinsvold, Lori Ann

    Discourse interactions between a teacher and students in an inquiry-based fourth-grade science classroom were analyzed to investigate how power dynamics and questioning strategies within elementary science lessons help support students in building their science understanding. Five inquiry-based classroom sessions were observed; verbal interactions were audio- and video-recorded. Research data consisted of observation transcripts, teacher interviews, student work, and instructional materials. Analyses were conducted on the frequencies of utterances, participation roles, power categories, and questioning categories. Results revealed that when students used more frequent power, (a) no significant differences were noted between frequencies of teacher and student talk, (b) the teacher posed more questions than did the students, and (c) students explained what they knew and asked questions to clarify their understanding. When the teacher used more frequent power, she asked questions to provide students opportunities to negotiate investigative processes and explain what they knew and how they knew it. Evidence of student understanding of the science concepts was found in how students used subject matter to discuss what they knew and how they knew it. Pre-service and in-service teachers should be encouraged to consider how their use of power and questioning strategies can engage students to reflect on how they build understanding of science concepts. Teachers can use Professional Learning Communities to reflect on how their practice engages students. Future research should be employed to observe classrooms across an entire school year to determine how power and questioning dynamics flow among students and teachers and change over time. Research can also be used to understand the influence of gender and culture on power and questioning dynamics in classroom settings.

    NASA Astrophysics Data System (ADS)

    Reinsvold, Lori A.; Cochran, Kathryn F.

    2012-11-01

    We describe the dynamic discourse interactions between a teacher and her students in a third-grade science classroom. We focused on how the teacher and students initiate, prompt, respond, and provide feedback; use questioning and power strategies; and how questions are associated with power dynamics. We relate the consequences of teacher use of power to the engagement of student with subject matter. Two classroom sessions were observed and teacher-student interactions audio recorded. Data were transcribed and a method was developed for analyzing teacher-student interactions, power dynamics, and types of questions asked. Results revealed that teacher talk was twice as frequent as students' talk; questions were primarily closed-ended and task-oriented; and students asked few questions. The teacher exercised power by keeping activities organized and conventional, and utilizing subject matter. The developed methods showed us the complexity of question and power dynamics in classroom discourse and have implications for professional development and research.

  1. Student questions in urban middle school science communities of practice

    NASA Astrophysics Data System (ADS)

    Groome, Meghan

    This dissertation examines student questions within three Communities of Practice (CoP), all urban middle school science environments. The study analyzed student questions from a sociocultural perspective and used ethnographic research techniques to detail how the CoP's shaped questions in the classroom. In the first study, two case study girls attempted to navigate questioning events that required them to negotiation participation. Their access to participation was blocked by participation frameworks that elevated some students as "gatekeepers" while suppressing the participation of others. The next two studies detail the introduction of written questioning opportunities, one into a public middle school classroom and the other into an informal classroom. In both studies, students responded to the interventions differently, most notable the adoption of the opportunity by female students who do not participate orally. Dissertation-wide findings indicate all students were able to ask questions, but varied in level of cognitive complexity, and the diagnostic interventions were able to identify students who were not known to be "target students", students who asked a high number of questions and were considered "interested in science". Some students' roles were as "gatekeepers" to participation of their peers. Two out of three teachers in the studies reported major shifts in their teaching practice due to the focus on questions and the methods used here have been found to be effective in producing educational research as well as supporting high-need classrooms in prior research. In conclusion, these studies indicate that social factors, including participation frameworks, gender dynamics, and the availability of alternative participation methods, play an important role in how students ask science-related questions. It is recommended that researchers continue to examine social factors that reduce student questions and modify their teaching strategies to facilitate

    2003-05-01

    "Cosmic Questions: Our Place in Space and Time" is a major new traveling exhibition and education project that will enable millions of Americans to learn how recent discoveries have shed light on-and raised new questions about-our place in the cosmos. Created by the Smithsonian Astrophysical Observatory with funding from the National Science Foundation and from NASA's Office of Space Science, the highly interactive exhibition opened at Boston's Museum of Science this past fall. In February 2003 it began its 3-year national tour under the management of the Association of Science-Technology Centers. Staff from the Museum of Science, in partnership with the CfA, developed a comprehensive set of educational programs, activities and events for museum staff, for teachers and students, and for public audiences. Both the exhibition and accompanying programs involve audiences in learning about the tools, techniques, and research that have allowed us to find some amazing answers to such enduring questions as: What is our place in the universe? Was there a beginning to time? How do we fit in? Evaluation data- including extensive observations, exit interviews, and follow-up phone surveys- suggest that a large majority of visitors could describe new learning and articulate new questions they had as a result of experiencing Cosmic Questions exhibits and programs. Indeed, the evaluation report states that "those interviewed often volunteered an unusual amount of reflective comments compared to visitors at other exhibits." This presentation will highlight how the content, approach, design, development and implementation of this project were (and continue to be) shaped by the significant involvement and contributions of astronomers, observatories and space science education and public outreach programs.

    Eshach, Haim; Dor-Ziderman, Yair; Yefroimsky, Yana

    2013-06-01

    Despite the wide agreement among educators that classroom learning and teaching processes can gain much from student and teacher questions, their potential is not fully utilized. Adopting the view that reporting both teachers' (of varying age groups) views and actual classroom practices is necessary for obtaining a more complete view of the phenomena at hand, the present study closely examines both cognitive and affective domains of: (a) teachers' views (via interviews) concerning: (1) importance and roles of teacher and student questions, (2) teacher responses, and (3) planning and teacher training; and (b) teachers' actual practices (via classroom observations) concerning: (1) number and (2) level of teacher and student questions, as well as (3) teachers' responses to questions. The data were collected from 3 elementary, 3 middle, and 3 high school science teachers and their respective classroom students. The findings lay out a wide view of classroom questioning and teachers' responses, and relate what actually occurs in classes to teachers' stated views. Some of the study's main conclusions are that a gap exists between how science researchers and teachers view the role of teacher questions: the former highlight the cognitive domain, while the latter emphasize the affective domain.

  6. Student and teacher questioning during conversations about science

    NASA Astrophysics Data System (ADS)

    van Zee, Emily H.; Iwasyk, Marletta; Kurose, Akiko; Simpson, Dorothy; Wild, Judy

    2001-02-01

    This paper summarizes case studies developed by a group of collaborating educators. We investigated ways of speaking that encourage students to (a) formulate insightful questions about science topics and (b) express their own ideas during reflective discussions. The authors include elementary, high school, and college faculty. Subject-matter contexts included phases of the moon, motion, electricity, light, and waves. In developing case studies, we documented and interpreted student and teacher questions during the three ways of speaking we value most: guided discussions, student-generated inquiry discussions, and peer collaborations. Student questions occurred when we set up discourse structures that explicitly elicited student questions, engaged students in conversations about familiar contexts in which they had made many observations over a long time period, created comfortable discourse environments in which students could try to understand one another's thinking, and established small groups where students were collaborating with one another. Typically we elicited student thinking by asking questions that develop conceptual understanding. These included questions to help students clarify their meanings, explore various points of view in a neutral and respectful manner, and monitor the discussion and their own thinking. We also elicited student thinking by practicing quietness through long wait times, attentive silence, and reticence.

  8. Examining student-generated questions in an elementary science classroom

    NASA Astrophysics Data System (ADS)

    Diaz, Juan Francisco, Jr.

    This study was conducted to better understand how teachers use an argument-based inquiry technique known as the Science Writing Heuristic (SWH) approach to address issues on teaching, learning, negotiation, argumentation, and elaboration in an elementary science classroom. Within the SWH framework, this study traced the progress of promoting argumentation and negotiation (which led to student-generated questions) during a discussion in an elementary science classroom. Speech patterns during various classroom scenarios were analyzed to understand how teacher--student interactions influence learning. This study uses a mixture of qualitative and quantitative methods. The qualitative aspect of the study is an analysis of teacher--student interactions in the classroom using video recordings. The quantitative aspect uses descriptive statistics, tables, and plots to analyze the data. The subjects in this study were fifth grade students and teachers from an elementary school in the Midwest, during the academic years 2007/2008 and 2008/2009. The three teachers selected for this study teach at the same Midwestern elementary school. These teachers were purposely selected because they were using the SWH approach during the two years of the study. The results of this study suggest that all three teachers moved from using teacher-generated questions to student-generated questions as they became more familiar with the SWH approach. In addition, all three promoted the use of the components of arguments in their dialogs and discussions and encouraged students to elaborate, challenge, and rebut each other's ideas in a non-threatening environment. This research suggests that even young students, when actively participating in class discussions, are capable of connecting their claims and evidence and generating questions of a higher-order cognitive level. These findings demand the implementation of more professional development programs and the improvement in teacher education to help

  9. Using questions sent to an Ask-A-Scientist site to identify children's interests in science

    2006-11-01

    Interest is a powerful motivator; nonetheless, science educators often lack the necessary information to make use of the power of student-specific interests in the reform process of science curricula. This study suggests a novel methodology, which might be helpful in identifying such interests - using children's self-generated questions as an indication of their scientific interests. In this research, children's interests were measured by analyzing 1555 science-related questions submitted to an international Ask-A-Scientist Internet site. The analysis indicated that the popularity of certain topics varies with age and gender. Significant differences were found between children's spontaneous (intrinsically motivated) and school-related (extrinsically motivated) interests. Surprisingly, girls contributed most of the questions to the sample; however, the number of American girls dropped upon entering senior high school. We also found significant differences between girls' and boys' interests, with girls generally preferring biological topics. The two genders kept to their stereotypic fields of interest, in both their school-related and spontaneous questions. Children's science interests, as inferred from questions to Web sites, could ultimately inform classroom science teaching. This methodology extends the context in which children's interests can be investigated.

    2016-04-01

    Recently, the pathobiology, causes, associated factors, incidence and prevalence, and natural history of chronic traumatic encephalopathy (CTE) have been debated. Data from retrospective case series and high-profile media reports have fueled public fear and affected the medical community's understanding of the role of sports-related traumatic brain injury (TBI) in the development of CTE. There are a number of limitations posed by the current evidence that can lead to confusion within the public and scientific community. In this paper, the authors address common questions surrounding the science of CTE and propose future research directions. PMID:27032918

  11. Big questions, big science: meeting the challenges of global ecology.

    PubMed

    Schimel, David; Keller, Michael

    2015-04-01

    Ecologists are increasingly tackling questions that require significant infrastucture, large experiments, networks of observations, and complex data and computation. Key hypotheses in ecology increasingly require more investment, and larger data sets to be tested than can be collected by a single investigator's or s group of investigator's labs, sustained for longer than a typical grant. Large-scale projects are expensive, so their scientific return on the investment has to justify the opportunity cost-the science foregone because resources were expended on a large project rather than supporting a number of individual projects. In addition, their management must be accountable and efficient in the use of significant resources, requiring the use of formal systems engineering and project management to mitigate risk of failure. Mapping the scientific method into formal project management requires both scientists able to work in the context, and a project implementation team sensitive to the unique requirements of ecology. Sponsoring agencies, under pressure from external and internal forces, experience many pressures that push them towards counterproductive project management but a scientific community aware and experienced in large project science can mitigate these tendencies. For big ecology to result in great science, ecologists must become informed, aware and engaged in the advocacy and governance of large ecological projects. PMID:25680334

  14. Planetary science questions for the manned exploration of Mars

    NASA Technical Reports Server (NTRS)

    Blanchard, Douglas P.

    1986-01-01

    A major goal of a manned Mars mission is to explore the planet and to investigate scientific questions for which the intensive study of Mars is essential. The systematic exploration of planets was outlined by the National Academy of Science. The nearest analogy to the manned Mars mission is the Apollo program and manned missions to the Moon, but the analogy is limited. The case is argued here that Mars may have to be explored far more systematically than was the pre-Apollo Moon to provide the detailed information necessary if plans are made to use any of the resources available on Mars. Viking missions provided a wealth of information, yet there are great gaps in the fundamental knowledge of essential facts such as the properties of the Martian surface materials and their interaction with the atmosphere. Building on a strong data base of precursor missions, human exploration will allow great leaps in understanding the Martian environment and geologic history and its evolutionary role in the solar system.

  15. New Indivisible Planetary Science Paradigm: Consequence of Questioning Popular Paradigms

    NASA Astrophysics Data System (ADS)

    Marvin Herndon, J.

    2014-05-01

    Progress in science involves replacing less precise understanding with more precise understanding. In science and in science education one should always question popular ideas; ask "What's wrong with this picture?" Finding limitations, conflicts or circumstances that require special ad hoc consideration sometimes is the key to making important discoveries. For example, from thermodynamic considerations, I found that the 'standard model of solar system formation' leads to insufficiently massive planetary cores. That understanding led me to discover a new indivisible planetary science paradigm. Massive-core planets formed by condensing and raining-out from within giant gaseous protoplanets at high pressures and high temperatures, accumulating heterogeneously on the basis of volatility with liquid core-formation preceding mantle-formation; the interior states of oxidation resemble that of the Abee enstatite chondrite. Core-composition was established during condensation based upon the relative solubilities of elements, including uranium, in liquid iron in equilibrium with an atmosphere of solar composition at high pressures and high temperatures. Uranium settled to the central region and formed planetary nuclear fission reactors, producing heat and planetary magnetic fields. Earth's complete condensation included a ~300 Earth-mass gigantic gas/ice shell that compressed the rocky kernel to about 66% of Earth's present diameter. T-Tauri eruptions, associated with the thermonuclear ignition of the Sun, stripped the gases away from the Earth and the inner planets. The T-Tauri outbursts stripped a portion of Mercury's incompletely condensed protoplanet and transported it to the region between Mars and Jupiter where it fused with in-falling oxidized condensate from the outer regions of the Solar System, forming the parent matter of ordinary chondrite meteorites, the main-Belt asteroids, and veneer for the inner planets, especially Mars. With its massive gas/ice shell

Flexible lesson planning over 14 lessons across a 4-week period of high school chemistry accommodated students' contributions and increased student participation, promoted inquiring and individualised teaching, with each teaching strategy feeding forward into the next.

  20. A comparative study of six decades of general science textbooks: Evaluating the evolution of science content

    NASA Astrophysics Data System (ADS)

    Lewis, Anna

    This study examined science textbooks over time to better understand the science content expectations that the U.S. educational system deems appropriate for 8th and 9th grade science students. The study attempted to answer the questions: (1) What specific science content has been presented via the textbook from 1952 to 2008? (2) Within which areas and in what way does the science content change? (3) Are new scientific findings reflected in 8th and 9th grade U.S. general science textbooks? Twenty-six themes were identified which reflect five areas in science: Chemistry, Physics, Earth Science, Biology, and Process of Science. Trends in science content in U.S. 8th and 9th grade general science textbooks, as revealed by this data sample, indicated no statistically significant change in depth of coverage in Physics and Process of Science over the past 60 years, no significant change in depth of coverage in Earth Science and Biology in the last 40 years, and no significant change in coverage in Chemistry over the last 30 years. Additionally, a total of sixteen new discoveries were found in the textbook sample. For classroom teachers this information may alert them to the necessity of going beyond the textbook in preparing students for life in a global society. In educational practice, this research supports and reinforces the need for inquiry learning and socioscientific curricula. It may also influence educators to challenge assumptions regarding the value and selection of the traditional classic science content.

    SOFIA is a joint project between NASA and DLR, the German Aerospace Center, to provide the worldwide astronomical community with an observatory that offers unique capabilities from visible to far-infrared wavelengths. SOFIA consists of a 2.7-m telescope mounted in a highly modified Boeing 747-SP aircraft, a suite of instruments, and the scientific and operational infrastructure to support the observing program. This paper describes the current status of the observatory and details the General Investigator program. The observatory has recently completed major development activities, and it has transitioned into full operational status. Under the General Investigator program, astronomers submit proposals that are peer reviewed for observation on the facility. We describe the results from the first two cycles of the General Investigator program. We also describe some of the new observational capabilities that will be available for Cycle 3, which will begin in 2015.

    Recent studies question the effectiveness of a traditional university curriculum in helping students improve their critical thinking and scientific literacy. We developed an introductory, general education (gen ed) science course to overcome both deficiencies. The course, titled Foundations of Science, differs from most gen ed science offerings in that it is interdisciplinary; emphasizes the nature of science along with, rather than primarily, the findings of science; incorporates case studies, such as the vaccine-autism controversy; teaches the basics of argumentation and logical fallacies; contrasts science with pseudoscience; and addresses psychological factors that might otherwise lead students to reject scientific ideas they find uncomfortable. Using a pretest versus posttest design, we show that students who completed the experimental course significantly improved their critical-thinking skills and were more willing to engage scientific theories the general public finds controversial (e.g., evolution), while students who completed a traditional gen ed science course did not. Our results demonstrate that a gen ed science course emphasizing the process and application of science rather than just scientific facts can lead to improved critical thinking and scientific literacy.

  8. Negotiating the question: using science-manager communication to develop management-relevant science products

    NASA Astrophysics Data System (ADS)

    Beechie, T. J.; Snover, A. K.

    2014-12-01

    Natural resource managers often ask scientists to answer questions that cannot be answered, and scientists commonly offer research that is not useful to managers. To produce management-relevant science, managers and scientists must communicate clearly to identify research that is scientifically doable and will produce results that managers find useful. Scientists might also consider that journals with high impact scores are rarely used by managers, while managers might consider that publishing in top tier journals is important to maintain scientific credentials. We offer examples from climate change and river restoration research, in which agency scientists and managers worked together to identify key management questions that scientists could answer and which could inform management. In our first example, we describe how climate scientists worked with agency staff to develop guidance for selecting appropriate climate change scenarios for use in ecological impacts assessments and Endangered Species Act decision making. Within NOAA Fisheries, agency researchers provide science to guide agency managers, and a key question has been how to adapt river restoration efforts for climate change. Based on discussions with restoration practitioners and agency staff, we developed adaptation guidance that summarizes current science to lead managers to develop climate-resilient restoration plans, as well as maps of population vulnerability for endangered steelhead. From these experiences we have learned that collaborative definition of relevant and producible knowledge requires (1) iterative discussions that go beyond simply asking managers what they need or scientists what they can produce, and (2) candid conversation about the intended applications and potential limitations of the knowledge.

    2012-06-01

    This paper reports on an attempt to investigate Turkish primary school students' interest in science by using their self-generated questions. We investigated students' interest in science by analyzing 1704 self-generated science-related questions. Among them, 826 questions were submitted to a popular science magazine called Science and Children. Such a self-selected sample may represent a group of students who have a higher level of motivation to seek sources of information outside their formal education and have more access to resources than the students of low social classes. To overcome this problem, 739 students were asked to write a question that they wanted to learn from a scientist and as a result 878 questions were gathered. Those students were selected from 13 different schools at 9 cities in Turkey. These schools were selected to represent a mixture of socioeconomic areas and also to cover different students' profile. Students' questions were classified into two main categories: the field of interest and the cognitive level of the question. The results point to the popularity of biology, astrophysics, nature of scientific inquiry, technology and physics over other science areas, as well as indicating a difference in interest according to gender, grade level and the setting in which the questions were asked. However, our study suggests that only considering questions submitted to informal learning environments, such as popular science magazines or Ask-A-Scientist Internet sites has limitations and deficiencies. Other methodologies of data collection also need to be considered in designing teaching and school science curriculum to meet students' needs and interest. The findings from our study tend to challenge existing thinking from other studies. Our results show that self-generated questions asked in an informal and a formal setting have different patterns.

  12. Using Art to Teach Students Science Outdoors: How Creative Science Instruction Influences Observation, Question Formation, and Involvement

    NASA Astrophysics Data System (ADS)

    Cone, Christina Schull

    Elementary education has become increasingly divided into subjects and focused on the demand for high math and reading scores. Consequently, teachers spend less time devoted to science and art instruction. However, teaching art and science is crucial to developing creative and rational thinking, especially for observation and questioning skills. In this study, third grade students attending an urban school in Portland, Oregon received instruction of an art strategy using observational and quantifying drawing techniques. This study examines, "Will an art strategy observing the local environment help students make observations and ask questions?" and "In what ways are student learning and perspectives of science affected by the art strategy?" The independent variable is the art strategy developed for this study. There are three dependent variables: quality of student observations, quality of questions, and themes on student learning and perspectives of science. I predicted students would develop strong observation and questioning skills and that students would find the strategy useful or have an increased interest in science. The art scores were high for relevance and detail, but not for text. There were significant correlations between art scores and questions. Interviews revealed three themes: observations create questions, drawing is helpful and challenging, and students connected to science. By examining science through art, students were engaged and created strong observations and questions. Teachers need to balance unstructured drawing time with scaffolding for optimal results. This study provides an integrated science and art strategy that teachers can use outdoors or adapt for the classroom.

    Classroom discourse can affect various aspects of student learning in science. The present study examines interactions between classroom discourse, specifically teacher questioning, and related student cognitive engagement in middle school science. Observations were conducted throughout the school year in 10 middle school science classrooms using the Electronic Quality of Inquiry Protocol, which is designed, among other things, to measure observable aspects of student cognitive engagement and discourse factors during science instruction. Results from these observations indicate positive correlations between students' cognitive engagement and the following aspects of classroom discourse: questioning level, complexity of questions, questioning ecology, communication patterns, and classroom interactions. A sequential explanatory mixed-methods design provides a detailed look at each aspect of classroom discourse which showed a positive effect on student cognitive level during science instruction. Implications for classroom practice, teacher education, and professional development are discussed.

    Urban, David; Chiaramonte, Francis P.

    2012-01-01

    Building upon a long history of spaceflight and ground based research, NASA's Combustion Science program has accumulated a significant body of accomplishments on the ISS. Historically, NASAs low-gravity combustion research program has sought: to provide a more complete understanding of the fundamental controlling processes in combustion by identifying simpler one-dimensional systems to eliminate the complex interactions between the buoyant flow and the energy feedback to the reaction zone to provide realistic simulation of the fire risk in manned spacecraft and to enable practical simulation of the gravitational environment experienced by reacting systems in future spacecraft. Over the past two decades, low-gravity combustion research has focused primarily on increasing our understanding of fundamental combustion processes (e.g. droplet combustion, soot, flame spread, smoldering, and gas-jet flames). This research program was highly successful and was aided by synergistic programs in Europe and in Japan. Overall improvements were made in our ability to model droplet combustion in spray combustors (e.g. jet engines), predict flame spread, predict soot production, and detect and prevent spacecraft fires. These results provided a unique dataset that supports both an active research discipline and also spacecraft fire safety for current and future spacecraft. These experiments have been conducted using the Combustion Integrated Rack (CIR), the Microgravity Science Glovebox and the Express Rack. In this paper, we provide an overview of the earlier space shuttle experiments, the recent ISS combustion experiments in addition to the studies planned for the future. Experiments in combustion include topics such as droplet combustion, gaseous diffusion flames, solid fuels, premixed flame studies, fire safety, and super critical oxidation processes.

    2014-06-15

    Information is the foundation of evidence-based policies for effective marine environmental protection and conservation. In Canada, the cutback of marine science libraries introduces key questions about the role of such institutions and the management of ocean information in the digital age. How vital are such libraries in the mission of studying and protecting the oceans? What is the fate and value of the massive grey literature holdings, including archival materials, much of which is not in digital form but which often contains vital data? How important is this literature generally in the marine environmental sciences? Are we likely to forget the history of the marine pollution field if our digital focus eclipses the need for and access to comprehensive collections and skilled information specialists? This paper explores these and other questions against the backdrop of unprecedented changes in the federal libraries, marine environmental science and legislation in Canada. PMID:24768172

  8. So much more than just a list: exploring the nature of critical questioning in undergraduate sciences

    NASA Astrophysics Data System (ADS)

    Pedrosa-de-Jesus, Helena; Moreira, Aurora; Lopes, Betina; Watts, Mike

    2014-05-01

    Background: Critical thinking is one of the very highest orders of cognitive abilities and a key competency in higher education. Asking questions is an important component of rich learning experiences, structurally embedded in the operations of critical thinking. Our clear sense is that critical thinking and, within that, critical questioning, is heavily context dependent, in the sense that is applied, used by critical learners in a contextualised way. Purpose: Our research deals with enhancing science undergraduates' critical questioning. We are interested in understanding and describing the nature and development of students' critical questioning. The purpose is to conceptualise critical questioning as a competency, into three domains - knowledge, skills and attitudes/dispositions. We have no interest in a taxonomic category of context-free question-types called 'critical questions'. In contrast, our view is that 'being a critical questioner' trades heavily on context. Sources of evidence: Four cases are considered as illuminative of the dimensions of science undergraduates' critical questioning. Data were collected in natural learning environments through non-participant observation, audio-taping teacher-students interactions and semi-structured interviews. Students' written material resulting from diverse learning tasks was also collected. Main argument: Our supposition is that one vehicle for achieving university students as critical thinkers is to enable them not just to ask critical questions, but to be critical questioners. We relate critical questioning to three domains: (1) context, (2) competency and (3) delivery, and propose a model based on illuminating examples of the in-classroom action. Conclusions: The dimensions of the competency-context-delivery model provide a framework for describing successful student critical questioning, showing that students' capacity to be critical can be developed. It is possible, in our view, to generate critical

  11. Selective attentional effects of textbook study questions on student learning in science

    NASA Astrophysics Data System (ADS)

    Holliday, William G.

    A selective attentional model used to explain recent mathemagenic and related research findings also predicted that textbook study questions adjunct to a flow diagram focus students' attention more upon questioned information and less upon nonquestioned information. Furthermore, the chances of such dysfunctional selective attention are increased when students are provided with a mere sampling (partial set) of study questions covering only portions of the diagram and are decreased when students are provided with a population (complete set) of questions or a no-question treatment. As predicted, using the Newman-Keuls procedure (p <0.05), the population and no-question treatment groups outperformed the sampling-question group which, in turn, outperformed a placebo-control group. It was concluded that researchers and teachers should be aware that encouraging students to concentrate on selective portions of critical information can result in inadequate processing of such specialized science materials as flow diagrams.

  12. Revisiting the Authoritative-Dialogic Tension in Inquiry-Based Elementary Science Teacher Questioning

    NASA Astrophysics Data System (ADS)

    Van Booven, Christopher D.

    2015-05-01

    Building on the 'questioning-based discourse analytical' framework developed by Singapore-based science educator and discourse analyst, Christine Chin, this study investigated the extent to which fifth-grade science teachers' use of questions with either an authoritative or dialogic orientation differentially restricted or expanded the quality and complexity of student responses in the USA. The author analyzed approximately 10 hours of classroom discourse from elementary science classrooms organized around inquiry-based science curricula and texts. Teacher questions and feedback were classified according to their dialogic orientation and contextually inferred structural purpose, while student understanding was operationalized as a dynamic interaction between cognitive process, syntacto-semantic complexity, and science knowledge type. The results of this study closely mirror Chin's and other scholars' findings that the fixed nature of authoritatively oriented questioning can dramatically limit students' opportunities to demonstrate higher order scientific understanding, while dialogically oriented questions, by contrast, often grant students the discursive space to demonstrate a greater breadth and depth of both canonical and self-generated knowledge. However, certain teacher questioning sequences occupying the 'middle ground' between maximal authoritativeness and dialogicity revealed patterns of meaningful, if isolated, instances of higher order thinking. Implications for classroom practice are discussed along with recommendations for future research.

    Nichols, Kim; Burgh, Gilbert; Kennedy, Callie

    2015-12-01

    Developing students' skills to pose and respond to questions and actively engage in inquiry behaviours enables students to problem solve and critically engage with learning and society. The aim of this study was to analyse the impact of providing teachers with an intervention in inquiry pedagogy alongside inquiry science curriculum in comparison to an intervention in non-inquiry pedagogy alongside inquiry science curriculum on student questioning and other inquiry behaviours. Teacher participants in the comparison condition received training in four inquiry-based science units and in collaborative strategic reading. The experimental group, the community of inquiry (COI) condition, received training in facilitating a COI in addition to training in the same four inquiry-based science units. This study involved 227 students and 18 teachers in 9 primary schools across Brisbane, Australia. The teachers were randomly allocated by school to one of the two conditions. The study followed the students across years 6 and 7 and students' discourse during small group activities was recorded, transcribed and coded for verbal inquiry behaviours. In the second year of the study, students in the COI condition demonstrated a significantly higher frequency of procedural and substantive higher-order thinking questions and other inquiry behaviours than those in the comparison condition. Implementing a COI within an inquiry science curriculum develops students' questioning and science inquiry behaviours and allows teachers to foster inquiry skills predicated by the Australian Science Curriculum. Provision of inquiry science curriculum resources alone is not sufficient to promote the questioning and other verbal inquiry behaviours predicated by the Australian Science Curriculum.

  15. Patterns of response times and response choices to science questions: the influence of relative processing time.

    PubMed

    Heckler, Andrew F; Scaife, Thomas M

    2015-04-01

    We report on five experiments investigating response choices and response times to simple science questions that evoke student "misconceptions," and we construct a simple model to explain the patterns of response choices. Physics students were asked to compare a physical quantity represented by the slope, such as speed, on simple physics graphs. We found that response times of incorrect answers, resulting from comparing heights, were faster than response times of correct answers comparing slopes. This result alone might be explained by the fact that height was typically processed faster than slope for this kind of task, which we confirmed in a separate experiment. However, we hypothesize that the difference in response time is an indicator of the cause (rather than the result) of the response choice. To support this, we found that imposing a 3-s delay in responding increased the number of students comparing slopes (answering correctly) on the task. Additionally a significant proportion of students recognized the correct written rule (compare slope), but on the graph task they incorrectly compared heights. Finally, training either with repetitive examples or providing a general rule both improved scores, but only repetitive examples had a large effect on response times, thus providing evidence of dual paths or processes to a solution. Considering models of heuristics, information accumulation models, and models relevant to the Stroop effect, we construct a simple relative processing time model that could be viewed as a kind of fluency heuristic. The results suggest that misconception-like patterns of answers to some science questions commonly found on tests may be explained in part by automatic processes that involve the relative processing time of considered dimensions and a priority to answer quickly.

  17. Neoliberal ideology, global capitalism, and science education: engaging the question of subjectivity

    NASA Astrophysics Data System (ADS)

    Bazzul, Jesse

    2012-12-01

    This paper attempts to add to the multifaceted discussion concerning neoliberalism and globalization out of two Cultural Studies of Science Education journal issues along with the recent Journal of Research in Science Teaching devoted to these topics. However, confronting the phenomena of globalization and neoliberalism will demand greater engagement with relevant sociopolitical thought in fields typically outside the purview of science education. Drawing from thinkers Michel Foucault, Jean Baudrillard, Judith Butler, and Louis Althusser this paper attempts to extend some key ideas coming from Ken Tobin, Larry Bencze, and Lyn Carter and advocates science educators taking up notions of ideology, discourse, and subjectivity to engage globalization and neoliberalism. Subjectivity (and its constitution in science education) is considered alongside two relevant textbook examples and also in terms of its importance in formulating political and culturally relevant questions in science education.

    Cano, Francisco; García, Ángela; Berbén, A. B. G.; Justicia, Fernando

    2014-07-01

    The purpose of this research was to build and test a conceptual model of the complex interrelationships between students' learning in science (learning approaches and self-regulation), their reading comprehension, question-asking in class and science achievement. These variables were measured by means of a test and a series of questionnaires administered to 604 ninth-grade students, and the data collected were analysed using a correlational, cross-sectional design. Results of a path analysis indicated that (a) students' self-regulated and intentional knowledge-constructing activity (self-regulated strategy use, deep approach and knowledge-building) were what chiefly accounted for their question-asking in class; (b) question-asking (high and low levels) was related directly to reading comprehension and indirectly, through its contribution to the this, to academic achievement; (c) reading comprehension was directly and negatively associated with surface approach and indirectly and positively related to deep approach and knowledge-building; and (d) some of these variables, particularly reading comprehension, accounted for academic achievement in science. This model explained nearly 30% of the variance in academic achievement and provided a substantial and distinctive insight into the web of interrelationships among these variables. Implications for future research and science teaching and learning are discussed (e.g. the importance of supporting students' efforts to learn science in a meaningful, active and self-regulated way and of improving their reading comprehension).

  2. Examining two Turkish teachers' questioning patterns in secondary school science classrooms

    Cikmaz, Ali

    This study examined low and high level teachers' questioning patterns and classroom implementations within an argument-based inquiry approach known as the Science Writing Heuristic (SWH) approach, which addresses issues on negotiation, argumentation, learning, and teaching. The level of the teachers was determined by the students' writing scores. This study was conducted in Turkey with seven teacher for preliminary study. Because scoring writing samples examines the students' negotiation level with the different sources and students learn scientific process, as negotiation, which they may transfer into their writing, in classroom, two teachers were selected to represent low and high level teachers. Data collection involved classroom observation through video recordings. The comparative qualitative method was employed throughout the data analysis process with including quantitative results. The research questions that guided the present study were: (1) How are low and high level teachers, determined according to their students' writing scores, questioning patterns different from each other during classroom discourse? (2) Is there a relationship between students' writings and teachers' questioning styles in the classroom? Analysis of Qualitative data showed that teachers' classroom implementations reveal big differences based on argumentation patterns. The high level teacher, whose students had high scores in writing samples, asked more questions and the cognitive levels of questions were higher than the low level teacher. Questions promote an argumentative environment and improve critical thinking skills by discussing different ideas and claims. Asking more questions of teacher influences students to initiate (ask questions) more and to learn the scientific process with science concepts. Implicitly, this learning may improve students' comparison in their writing. Moreover, high level teacher had a more structured and organized classroom than low level teacher.

  4. How commercial and ``violent'' video games can promote culturally sensitive science learning: some questions and challenges

    2012-12-01

    In their paper, Muñoz and El-Hani propose to bring video games into science classrooms to promote culturally sensitive ethics and citizenship education. Instead of bringing "educational" games, Muñoz and El-Hani take a more creative route and include games such as Fallout 3® precisely because they are popular and they reproduce ideological and violent representations of gender, race, class, nationality, science and technology. However, there are many questions that arise in bringing these commercial video games into science classrooms, including the questions of how students' capacities for critical reflection can be facilitated, whether traditional science teachers can take on the role of using such games in their classrooms, and which video games would be most appropriate to use. In this response, I raise these questions and consider some of the challenges in order to further the possibility of implementing Muñoz and El-Hani's creative proposal for generating culturally sensitive science classrooms.

  6. The use of why-questions to enhance college science students' comprehension of their textbooks

    NASA Astrophysics Data System (ADS)

    Smith, Betty Lou

    2002-01-01

    Why-questions adjunct to reading material consistently help students remember unfamiliar information (recall) according to research investigating elaborative interrogation. Why-questions ask students to explain why statements pulled-out from a text are true. But no one apparently has assessed why-questions' effectiveness when measuring comprehension of paraphrased meaningful information and when students are learning in a naturalistic classroom context. This study investigated the use of why-questions in enhancing science reading comprehension. Undergraduates (123 males and 171 females) using a chapter from their introductory biology textbooks were randomly assigned to a treatment group with 21 adjunct why-questions or to a control group with no adjunct why-questions. The treatment group was instructed to read the textbook material and to answer the why-questions. The control group was instructed to read the same textbook material twice, a standard methodological procedure used in such research. Posttest data was collected using a posttest only equivalent group design. A test for students' prior knowledge and a test for students' verbal ability were administered to the students prior to the study. Findings revealed that students in the treatment group using adjunct why-question outperformed (p < .05) students in the control group without why-questions on a comprehension posttest. Of interest is that students with low-verbal ability who answered adjunct why-questions significantly outperformed students with low-verbal ability in the control group. Why-questions seem to be a potentially powerful learning device to improve student comprehension of college biology textbooks.

    2015-12-01

    Each year, British Antarctic Survey (BAS) supports an extensive programme of science at five Antarctic and sub-Antarctic stations, ranging from the tiny Bird Island Research Station at 54°S in the South Atlantic, to the massive, and fully re-locatable, Halley Research Station on Brunt Ice Shelf at 75°S. The BAS logistics hub, Rothera Research Station on the Antarctic Peninsula supports deployment of deep-field and airborne field campaigns through much of the Antarctic continent, and an innovative new UK polar research vessel is under design, and planned to enter service in the Southern Ocean in 2019. BAS's core science programme covering all aspects of physical, biological and geological science is delivered by our own science teams, but every year many other UK scientists and overseas collaborators also access BAS's Antarctic logistics to support their own programmes. As an integrated science and logistics provider, BAS is continuously reviewing its capabilities and operational procedures to ensure that the future long-term requirements of science are optimally supported. Current trends are towards providing the capacity for heavier remote operations and larger-scale field camps, increasing use of autonomous ocean and airborne platforms, and increasing opportunities to provide turnkey solutions for low-cost experimental deployments. This talk will review of expected trends in Antarctic science and the opportunities to conduct science in Antarctica. It will outline the anticipated logistic developments required to support future stakeholder-led and strategically-directed science programmes, and the long-term ambitions of our science communities indentified in several recent horizon-scanning activities.

  10. Improving comprehension of science content: Generating self-explanation questions and creating explanatory answers

    NASA Astrophysics Data System (ADS)

    Clelland, Peggie L.

    The emphasis on learning in content area classrooms is heavily dependent on remembering facts and memorizing definitions. Because of this, students often achieve shallow levels of comprehension and are deficient in the skills necessary to achieve deeper comprehension. Teaching students to generate self-explanation questions and answers related to teacher lectures and from reading text can improve comprehension. Students who attempt to explain what the content means understand it better and at a deeper level. The purpose of this study was to examine the effectiveness of teaching students to ask self-explanation questions as a means for improving comprehension. Eighth-grade students from three heterogeneous science classrooms participated in one of the treatment or comparison groups. The first treatment group was taught to generate self-explanation questions while the second treatment group was taught to generate self-explanation questions and to create explanatory answers using a rubric. The comparison group received their regular science instruction. Self-explanation question/answer participants scored significantly higher than the regular instruction group more often than the self-explanation question only group, on memory and essay measures. Analyses were performed with MANCOVA on all three groups' scores as a set. ANCOVA was used to determine if differences existed between groups on each of the dependent variables, and Bonferonni's post-hoc contrasts were used to determine where differences existed among treatment and comparison groups. Results revealed that students who were taught to generate self-explanation questions and/or to create explanatory answers outperformed the regular instruction students on some of the memory and essay measures. Additionally, teaching students a self-explanation strategy resulted in improved ability to respond to essay questions two weeks following the conclusion of the study compared to students who received regular instruction.

  11. Differential effects of verbal aptitude and study questions on comprehension of science concepts

    NASA Astrophysics Data System (ADS)

    Holliday, William G.; Whittaker, Harold G.; Loose, Kenneth D.

    Selective attention models predict that verbatim study questions can divert students from meaningfully encoding attributes of science concepts. The aptitude-treatment interaction (ATI) hypothesis predicts that such questions can be particularly dysfunctional to low-ability students. These predictions assume the measurement of true comprehension of concepts as a criterion. Eighth-grade students (n = 217) were randomly assigned to a text-only, text-question or a placebo treatment. The text verbally described five fossil types. The questions consisted of 28 fill-in-the-blank queries about the text. The posttest required students to visually identify and discriminate 40 fossil specimens as to fossil type. Comprehension of the concepts clearly took place-a fact substantiated by the very low scores obtained by the placebo group. As predicted (p < 0.05), low-verbal students performed better when provided with a text-only rather than a text-question treatment. In contrast, high-verbal students were less effected by the verbatim study questions. Main effects among these groups were also detected. Apparently such questions can overprompt students, resulting in their copying of words from a text to an answer-blank without semantically encoding (i.e., comprehending) the copied words.

    2003-07-01

    This article reports on a research project designed to explore a group of women scientists' understandings of themselves and science. The project uses an unconventional methodology: - a mixture of conventional qualitative research methods and techniques developed for use in psychotherapy. Its preliminary results appear to contradict some of the assumptions on which much of past work on girls and science education is based. For example, we found that, for the women involved in this project, factors such as the presence in their lives of strong female role models and/or the use of 'girl-friendly' curriculum materials were not important in their decision to continue the study of science to university level. Other factors - some of which were quite unexpected - had a much greater effect. The article outlines the methodology of this project and some of its findings, and explores the implications of these findings for future work on the gender and science education question.

  15. Science anxiety and social cognitive factors predicting STEM career aspirations of high school freshmen in general science class

    NASA Astrophysics Data System (ADS)

    Skells, Kristin Marie

    Extant data was used to consider the association between science anxiety, social cognitive factors and STEM career aspirations of high school freshmen in general science classes. An adapted model based on social cognitive career theory (SCCT) was used to consider these relationships, with science anxiety functioning as a barrier in the model. The study assessed the following research questions: (1) Do social cognitive variables relate in the expected way to STEM career aspirations based on SCCT for ninth graders taking general science classes? (2) Is there an association between science anxiety and outcomes and processes identified in the SCCT model for ninth graders taking general science classes? (3) Does gender moderate these relationships? Results indicated that support was found for many of the central tenants of the SCCT model. Science anxiety was associated with prior achievement, self-efficacy, and science interest, although it did not relate directly to STEM career goals. Gender was found to moderate only the relationship between prior achievement and science self-efficacy.

  17. The questions of scientific literacy and the challenges for contemporary science teaching: An ecological perspective

    NASA Astrophysics Data System (ADS)

    Kim, Mijung

    This study began with questions about how science education can bring forth humanity and ethics to reflect increasing concerns about controversial issues of science and technology in contemporary society. Discussing and highlighting binary epistemological assumptions in science education, the study suggests embodied science learning with human subjectivity and integrity between knowledge and practice. The study questions (a) students' understandings of the relationships between STSE and their everyday lifeworld and (b) the challenges of cultivating scientific literacy through STSE teaching. In seeking to understand something about the pedagogical enactment of embodied scientific literacy that emphasizes the harmony of children's knowledges and their lifeworlds, this study employs a mindful pedagogy of hermeneutics. The intro- and intra-dialogical modes of hermeneutic understanding investigate the pedagogical relationship of parts (research texts of students, curriculum, and social milieu) and the whole (STSE teaching in contemporary time and place). The research was conducted with 86 Korean 6 graders at a public school in Seoul, Korea in 2003. Mixed methods were utilized for data collection including a survey questionnaire, a drawing activity, interviews, children's reflective writing, and classroom teaching and observation. The research findings suggest the challenges and possibilities of STSE teaching as follows: (a) children's separated knowledge from everyday practice and living, (b) children's conflicting ideas between ecological/ethical aspects and modernist values, (c) possibilities of embodied knowing in children's practice, and (d) teachers' pedagogical dilemmas in STSE teaching based on the researcher's experiences and reflection throughout teaching practice. As further discussion, this study suggests an ecological paradigm for science curriculum and teaching as a potential framework to cultivate participatory scientific literacy for citizenship in

    Over the past three decades, Earth scientists have made great strides in understanding our planet’s workings and history. Yet this progress has served principally to lay bare more fundamental questions about the Earth. Expanding knowledge is generating new questions, while innovative technologies and new partnerships with other sciences provide new paths toward answers. A National Academies committee was established to frame some of the great intellectual challenges inherent in the study of the Earth and planets. The goal was to focus on science, not implementation issues, such as facilities or recommendations aimed at specific agencies. The committee canvassed the geological community and deliberated at length to arrive at 10 questions: 1. How did Earth and other planets form? 2. What happened during Earth’s “dark age” (the first 500 million years)? 3. How did life begin? 4. How does Earth’s interior work, and how does it affect the surface? 5. Why does Earth have plate tectonics and continents? 6. How are Earth processes controlled by material properties? 7. What causes climate to change—and how much can it change? 8. How has life shaped Earth—and how has Earth shaped life? 9. Can earthquakes, volcanic eruptions, and their consequences be predicted? 10. How do fluid flow and transport affect the human environment? Written for graduate students, colleagues in sister disciplines, and program managers funding Earth and planetary science research, the report describes where the field stands, how it got there, and where it might be headed. Our hope is that the report will spark new interest in and support for the field by showing how Earth science can contribute to a wide range of issues—including some not always associated with the solid Earth—from the formation of the solar system to climate change to the origin of life. Its reach goes beyond the United States; the report is being translated into Chinese and distributed in China.

    The speed and effectiveness of current approaches to research translation are widely viewed as disappointing given small gains in real population health outcomes despite huge investments in basic and translational science. We identify critical value questions—ethical, social, economic, and cultural—that arise at moments throughout the research pathway. By making these questions visible, and promoting discussion of them with diverse stakeholders, we can facilitate handoffs along the translational pathway and increase uptake of effective interventions. Who is involved with those discussions will determine which research projects, populations, and methods get prioritized. We argue that some upfront investment in community and interdisciplinary engagement, shaped by familiar questions in ethics, social justice, and cultural knowledge, can save time and resources in the long run because interventions and strategies will be aimed in the right direction, that is, toward health improvements for all.

    This report describes molecular techniques that could be invaluable in addressing process-oriented problems in the ocean sciences that have perplexed oceanographers for decades, such as understanding the basis for biogeochemical processes, recruitment processes, upper-ocean dynamics, biological impacts of global warming, and ecological impacts of human activities. The coupling of highly sophisticated methods, such as satellite remote sensing, which permits synoptic monitoring of chemical, physical, and biological parameters over large areas, with the power of modern molecular tools for ``ground truthing`` at small scales could allow scientists to address questions about marine organisms and the ocean in which they live that could not be answered previously. Clearly, the marine sciences are on the threshold of an exciting new frontier of scientific discovery and economic opportunity.

  3. Using Eight Key Questions as an Inquiry-Based Framework for Ethical Reasoning Issues in a General Education Earth Systems and Climate Change Course

    Johnson, E. A.; Ball, T. C.

    2014-12-01

    An important objective in general education geoscience courses is to help students evaluate social and ethical issues based upon scientific knowledge. It can be difficult for instructors trained in the physical sciences to design effective ways of including ethical issues in large lecture courses where whole-class discussions are not practical. The Quality Enhancement Plan for James Madison University, "The Madison Collaborative: Ethical Reasoning in Action," (http://www.jmu.edu/mc/index.shtml) has identified eight key questions to be used as a framework for developing ethical reasoning exercises and evaluating student learning. These eight questions are represented by the acronym FOR CLEAR and are represented by the concepts of Fairness, Outcomes, Responsibilities, Character, Liberty, Empathy, Authority, and Rights. In this study, we use the eight key questions as an inquiry-based framework for addressing ethical issues in a 100-student general education Earth systems and climate change course. Ethical reasoning exercises are presented throughout the course and range from questions of personal behavior to issues regarding potential future generations and global natural resources. In the first few exercises, key questions are identified for the students and calibrated responses are provided as examples. By the end of the semester, students are expected to identify key questions themselves and justify their own ethical and scientific reasoning. Evaluation rubrics are customized to this scaffolding approach to the exercises. Student feedback and course data will be presented to encourage discussion of this and other approaches to explicitly incorporating ethical reasoning in general education geoscience courses.

    NASA Astrophysics Data System (ADS)

    Davidson, Anne Burgess

    Did the Third International Mathematics and Science Study (TIMSS) ask science teachers the right questions about their use of instructional time? Part I of this 2-part study used the TIMSS database to answer the question: Do 8th grade science teachers in the U.S., Czech Republic, Hungary, Japan, and Korea differ significantly in their perceived use of instructional time? Using the instructional activities in the TIMSS teacher question "How did the lesson proceed?" the teacher-reported times were analyzed using a repeated measures multivariate analysis. Significant differences were found between teacher-reported times in the U.S. and the other 4 TIMSS countries, whose 8th grade students outperformed U.S. students on TIMSS achievement tests. Post-hoc analysis indicated that TIMSS U.S. 8th grade science teachers report spending more time on homework in class, on group activities, and on lab activities, but less time on topic development, than TIMSS teachers from some or all of the other countries. Part II of this study further examined the question "How did the lesson proceed?" by videotaping 6 classes of 8th grade science in Alabama and Virginia and comparing observer coding of the video to the teachers' recalled descriptions of the same class. The difference between observer and teacher responses using TIMSS categories was not significant; however, 43% of the total variance was explained by whether the teacher or the observer reported the times for the instructional activities. The teachers also responded to questions from the NSF Local Systemic Change Through Teacher Enhancement K--8 Teacher Questionnaire to describe the same class. The difference found between the teacher and the observer coding was not significant, but the amount of variance explained by the data source (observer or teacher) dropped to 33% when using NSF student activity categories and to 26% when using NSF teacher activity categories. The conclusion of this study was that questionnaires to

    A rising need for workers in science, technology, engineering and mathematics (STEM) fields has fueled interest in improving teaching within STEM disciplines. Numerous studies have demonstrated the benefits of active learning approaches on student learning outcomes. However, many of these studies have been conducted in experimental, rather than real-life class, settings. In addition, most of these studies have focused on in-class active learning exercises. This study tested the effects of answering questions outside of class on exam performance for General Biology students at the University of Minnesota. An online database of 1,020 multiple-choice questions covering material from the first half of the course was generated. Students in seven course sections (with an average of ∼265 students per section) were given unlimited access to the online study questions. These students made extensive use of the online questions, with students answering an average of 1,323 questions covering material from the half of the semester for which the questions were available. After students answered a set of questions, they were shown the correct answers for those questions. More specific feedback describing how to arrive at the correct answer was provided for the 73% of the questions for which the correct answers were not deemed to be self-explanatory. The extent to which access to the online study questions improved student learning outcomes was assessed by comparing the performance on exam questions of students in the seven course sections with access to the online study questions with the performance of students in course sections without access to the online study questions. Student performance was analyzed for a total of 89 different exams questions that were not included in the study questions, but that covered the same material covered by the study questions. Each of these 89 questions was used on one to five exams given to students in course sections that had access to the

    The ocean plays an important role in regulating the earth`s climate, sustains a large portion of the earth`s biodiversity, is a tremendous reservoir of commercially important substances, and is used for a variety of often conflicting purposes. In recent decades marine scientists have discovered much about the ocean and its organisms, yet many important fundamental questions remain unanswered. Human populations have increased, particularly in coastal regions. As a result, the marine environment in these areas is increasingly disrupted by human activities, including pollution and the depletion of some ecologically and commercially important species. There is a sense of urgency about reducing human impacts on the ocean and a need to understand how altered ecosystems and the loss of marine species and biodiversity could affect society. During the past two decades, the development of sophisticated technologies and instruments for biomedical research has resulted in significant advances in the biological sciences. While some of these technologies have been readily incorporated into the study of marine organisms as models for understanding basic biology, the value of molecular techniques for addressing problems in marine biology and biological oceanography has only recently begun to be appreciated. This report defines critical scientific questions in marine biology and biological oceanography, describes the molecular technologies that could be used to answer these questions, and discusses some of the implications and economic opportunities that might result from this research which could potentially improve the international competitive position of the United States in the rapidly growing area of marine biotechnology. The committee recommends that the federal government provide the infrastructure necessary to use the techniques of molecular biology in the marine sciences.

    Although the science behind the Sun is so fascinating, there has not been sufficient worldwide effort in presenting this science to the general public. My recently published popular science book "Nature's Third Cycle: A Story of Sunspots" (Oxford University Press, 2015) is probably the first popular science book introducing the phenomenology of the solar cycle along with a non-technical account of dynamo theory. I shall discuss my perspective of the challenges involved in presenting the science of the Sun to the public.

  10. How can comprehension adjunct questions focus students' attention and enhance concept learning of a computer-animated science lesson?

    NASA Astrophysics Data System (ADS)

    Holliday, William G.; McGuire, Barry

    Two focusing hypotheses were evaluated. First, do adjunct questions, focusing on science concepts and inserted after computer-animated sequences, selectively alter students' attentional or practice processing and thus produce differential learning effects? Theoretically, such questions selectively focus students' attention and enhance concept learning of focused concepts. Second, do these questions still provide enough metacognitive scaffolding to produce differential learning effects when only the first 8 out of 12 sequences are followed by focusing questions? Eighth-grade students (n = 160) were randomly assigned to a control group (lesson alone) or one of four treatment groups (lesson plus 12 questions focusing either on heat or on temperature, or lesson plus the same first 8 questions on heat or temperature followed by 4 placebo questions). Two significant two-way interactions with widely varying F ratios supported the differential focusing hypotheses (12 questions - more robust interaction, 8 - less robust interaction).

    Multiple choice questions play an important role in training and evaluating biomedical science students. However, the resource intensive nature of question generation limits their open availability, reducing their contribution to evaluation purposes mainly. Although applied-knowledge questions require a complex formulation process, the creation of concrete-knowledge questions (i.e., definitions, associations) could be assisted by the use of informatics methods. We envisioned a novel and simple algorithm that exploits validated knowledge repositories and generates concrete-knowledge questions by leveraging concepts' relationships. In this manuscript we present the development and validation of a prototype which successfully produced meaningful concrete-knowledge questions, opening new applications for existing knowledge repositories, potentially benefiting students of all biomedical sciences disciplines.

    For the past three decades, much attention has been focused on developing diversity programs designed to improve the academic success of underrepresented minorities, primarily in mathematics, science, and engineering. However, ethnic minorities remain underrepresented in science majors and careers. Over the last 10 years, the Biology Scholars Program (BSP), a diversity program at the University of California (UC), Berkeley, has worked to increase the participation and success of students majoring in the biological sciences. A quantitative comparison of students in and out of the program indicates that students in BSP graduate with a degree in biology at significantly higher rates than students not in BSP regardless of race/ethnicity. Furthermore, students who are in BSP have statistically lower high school grade point averages (GPAs) and Scholastic Achievement Test (SAT) scores than students not in BSP. African-American and Hispanic students who join BSP graduate with significantly higher UC Berkeley biology GPAs than non-BSP African-American and Hispanic students, respectively. Majority (Asian and White) students in BSP graduate with statistically similar UC GPAs despite having lower SAT scores than non-BSP majority students. Although BSP students are more successful in completing a biology degree than non-program members, the results raise a series of questions about why the program works and for whom. PMID:12888847

P., Reynolds-Alpert, S., and Mallow, J. V. (2001). Does physics teaching affect gender-based science anxiety? Journal of Science Education and Technology 10: 237-247] of science anxiety in various student cohorts suggested that nonscience majors were highly science anxious (SA), regardless of what science courses they were taking. In this study, we investigated science anxiety in a cohort consisting mostly of nonscience majors taking general education science courses. Regression analysis shows that the leading predictors of science anxiety are (i) nonscience anxiety and (ii) gender, as they were for different cohorts in the earlier studies. We confirm earlier findings that females are more SA than males. Chi-square analysis of acute science anxiety shows an amplification of these differences. We found statistically significant levels of science anxiety in humanities and social science students of both genders, and gender differences in science anxiety, despite the fact that the students were all enrolled in general education science courses specifically designed for nonscience majors. We found acute levels of anxiety in several groups, especially education, nursing, and business majors. We describe specific interventions to alleviate science anxiety.

  19. Impact of SCALE-UP on science teaching self-efficacy of students in general education science courses

    Cassani, Mary Kay Kuhr

    The objective of this study was to evaluate the effect of two pedagogical models used in general education science on non-majors' science teaching self-efficacy. Science teaching self-efficacy can be influenced by inquiry and cooperative learning, through cognitive mechanisms described by Bandura (1997). The Student Centered Activities for Large Enrollment Undergraduate Programs (SCALE-UP) model of inquiry and cooperative learning incorporates cooperative learning and inquiry-guided learning in large enrollment combined lecture-laboratory classes (Oliver-Hoyo & Beichner, 2004). SCALE-UP was adopted by a small but rapidly growing public university in the southeastern United States in three undergraduate, general education science courses for non-science majors in the Fall 2006 and Spring 2007 semesters. Students in these courses were compared with students in three other general education science courses for non-science majors taught with the standard teaching model at the host university. The standard model combines lecture and laboratory in the same course, with smaller enrollments and utilizes cooperative learning. Science teaching self-efficacy was measured using the Science Teaching Efficacy Belief Instrument - B (STEBI-B; Bleicher, 2004). A science teaching self-efficacy score was computed from the Personal Science Teaching Efficacy (PTSE) factor of the instrument. Using non-parametric statistics, no significant difference was found between teaching models, between genders, within models, among instructors, or among courses. The number of previous science courses was significantly correlated with PTSE score. Student responses to open-ended questions indicated that students felt the larger enrollment in the SCALE-UP room reduced individual teacher attention but that the large round SCALE-UP tables promoted group interaction. Students responded positively to cooperative and hands-on activities, and would encourage inclusion of more such activities in all of the

    The ocean plays an important role in regulating the earth`s climate, sustains a large portion of the earth`s biodiversity, is a tremendous reservoir of commercially important substances, and is used for a variety of often conflicting purposes. In recent decades marine scientists have discovered much about the ocean and its organisms, yet many important fundamental questions remain unanswered. Human populations have increased, particularly in coastal regions. As a result, the marine environment in these areas is increasingly disrupted by human activities, including pollution and the depletion of some ecologically and commercially important species. There is a sense of urgency about reducing human impacts on the ocean and a need to understand how altered ecosystems and the loss of marine species and biodiversity could affect society. This report describes molecular techniques that could be invaluable in addressing process-oriented problems in the ocean sciences that have perplexed oceanographers for decades, such as understanding the basis for biogeochemical processes, recruitment processes, upper-ocean dynamics, biological impacts of global warming, and ecological impacts of human activities. The coupling of highly sophisticated methods, such as satellite remote sensing, which permits synoptic monitoring of chemical, physical, and biological parameters over large areas, with the power of modern molecular tools for ground truthing at small scales could allow scientists to address questions about marine organisms and the ocean in which they live that could not be answered previously.

    The Convective and Orographically-induced Precipitation Study (COPS) was an international field campaign carried out in summer 2007 with the overall goal to advance the quality of forecasts of orographically-induced convective precipitation by 4-dimensional observations and modeling of its life cycle. The pre-convective environment, the formation of clouds and the onset and development of precipitation were observed in a low-mountain area in south-western Germany and eastern France covering the Vosges Mountains, the Rhine Valley, and the Black Forest Mountains during 18 Intensive Observations Periods from June 1 to August 31, 2007, under different forcing conditions. Meanwhile, in the nearly five years since the COPS field phase, a large number of results on analyses of selected COPS IOPs and of continuous measurements during the COPS period have been published; in a special issue of the Quarterly Journal of the Royal Meteorological Society alone, 21 papers appeared in January 2011. A second special issue on COPS results is currently in preparation for the Meteorologische Zeitschrift (MetZ). In this contribution, we will revisit the original science questions of COPS, summarize the results gained so far from COPS, and discuss questions which still remain open.

    Feelings of knowing (FoK) are introspective self-report ratings of the felt likelihood that one will be able to recognize a currently unrecallable memory target. Previous studies have shown that FoKs are influenced by retrieved fragment knowledge related to the target, which is compatible with the accessibility hypothesis that FoK is partly based on currently activated partial knowledge about the memory target. However, previous results have been inconsistent as to whether or not FoKs are influenced by the accuracy of such information. In our study (N = 26), we used a recall-judge-recognize procedure where stimuli were general knowledge questions. The measure of partial knowledge was wider than those applied previously, and FoK was measured before rather than after partial knowledge. The accuracy of reported partial knowledge was positively related to subsequent recognition accuracy, and FoK only predicted recognition on trials where there was correct partial knowledge. Importantly, FoK was positively related to the amount of correct partial knowledge, but did not show a similar incremental relation with incorrect knowledge. PMID:27445950

    In the conclusion to this multi-part article I first review the discussions carried out around the six essential questions in psychiatric diagnosis – the position taken by Allen Frances on each question, the commentaries on the respective question along with Frances’ responses to the commentaries, and my own view of the multiple discussions. In this review I emphasize that the core question is the first – what is the nature of psychiatric illness – and that in some manner all further questions follow from the first. Following this review I attempt to move the discussion forward, addressing the first question from the perspectives of natural kind analysis and complexity analysis. This reflection leads toward a view of psychiatric disorders – and future nosologies – as far more complex and uncertain than we have imagined. PMID:23249629

  6. Factors influencing the undergraduate general education science curriculum

    The state of scientific literacy in the United States has been the focus of increasing concern in recent decades. A great deal of the blame for failing to produce citizens with a broad perspective in science has been placed on the undergraduate general education science curriculum. This was a national study designed to examine the factors that influence instructors' decision-making processes in designing the undergraduate general education science curriculum. The study also gathered information on the approaches used to present the curriculum. A mail-in questionnaire was used to collect data on the goals and factors that influence instructors' decisions related to the content of their courses, and on the associated characteristics of the instructors and programs. Questionnaires were returned by 85 instructors, representing a wide range of undergraduate programs in general education science. Data were analyzed by descriptive statistics, t-tests, and ANOVA, comparing respondents' mean ratings of factors and goals related to course content decisions. In making decisions, respondents assigned highest importance to the following factors: (a) instructor's philosophy of general education, (b) current and future needs of students, (c) demands of the discipline, and (d) the desire to incorporate an interdisciplinary perspective. Factors rated as least important were (a) recognition for tenure or promotion, (b) governmental requirements or regulations, and (c) guidance of a general education committee. As a goal for their course, respondents placed highest priority on developing students' science inquiry skills. Analysis by various groupings such as type of institution, instructor's education level, and years of teaching experience revealed few significant differences among respondents' ratings of factors and goals. Based on the findings of this study, recommendations for improving the general education science curriculum include (a) assisting instructors in developing and

    2011-03-01

    The purpose of this study is to examine the effect of two strategies for negotiating the question for exploration during science inquiry on student achievement and teachers' perceptions. The study is set in the context of the Science Writing Heuristic. The first strategy (small group) consisted of each group of four students negotiating a question for inquiry with the teacher while the second strategy (whole class) consisted of the entire class negotiating a single question for inquiry with the teacher. The study utilized a mixed-method approach. A quasi-experimental repeated measures design was used to determine the effect of strategy on student achievement and semi-structured teacher interviews were used to probe the question of teacher perceptions of the two strategies. Teacher observations were conducted using the Reformed Teaching Observation Protocol (RTOP) to check for variation in implementation of the two strategies. Iowa Test of Basic Skills Science (ITBSS) (2005 and 2006) and teacher/researcher developed unit exams (pre and post) were used as student achievement measures. No statistically significant differences were found among students in the two treatment groups on the ITBSS or unit exams. RTOP observations suggest that teacher implementation was consistent across the two treatment strategies. Teachers disclosed personal preferences for the two strategies, indicating the whole class treatment was easier to manage (at least at the beginning of the school year) as students gained experience with science inquiry and the associated increased responsibility. Possible mechanisms linking the two strategies, negotiated questions, and student outcomes are discussed.

    The use of a mixed method research design raises many questions, especially regarding the paradigmatic position. With this paradigm, we may consider the mixed method design as the best way of answering a research question and the latter orients to one of the different subtypes of mixed method design. To illustrate the use of this kind of design, we propose a study such as conducted in nursing sciences. In this article, the challenges raised by the mixed method design, and the place of this type of research in nursing sciences is discussed. PMID:21322192

I report classification accuracies between 23% and 56%, obtaining substantial improvements by exploiting domain knowledge (compiler error messages) and educational context (assignment name). My results are especially timely and relevant for online courses where students are completing the same set of assignments asynchronously and access to staff is limited.

  7. General chemistry students' understanding of the chemistry underlying climate science

    NASA Astrophysics Data System (ADS)

    Versprille, Ashley N.

    The purpose of this study is to investigate first-semester general chemistry students' understanding of the chemistry underlying climate change. The first part of this study involves the collection of qualitative data from twenty-four first-semester general chemistry students from a large Midwestern research institution. The semi-structured interview protocol was developed based on alternative conceptions identified in the research literature and the essential principles of climate change outlined in the U.S. Climate Change Science Program (CCSP) document which pertain to chemistry (CCSP, 2003). The analysis and findings from the interviews indicate conceptual difficulties for students, both with basic climate literacy and underlying chemistry concepts. Students seem to confuse the greenhouse effect, global warming, and the ozone layer, and in terms of chemistry concepts, they lack a particulate level understanding of greenhouse gases and their interaction with electromagnetic radiation, causing them to not fully conceptualize the greenhouse effect and climate change. Based on the findings from these interviews, a Chemistry of Climate Science Diagnostic Instrument (CCSI) was developed for use in courses that teach chemistry with a rich context such as climate science. The CCSI is designed for professors who want to teach general chemistry, while also addressing core climate literacy principles. It will help professors examine their students' prior knowledge and alternative conceptions of the chemistry concepts associated with climate science, which could then inform their teaching and instruction.

  8. A framework for integrating and synthesizing data to ask and answer science questions in the Critical Zone

    In 2007, the U.S. Geological Survey (USGS) published a science strategy that resulted in an organizational pivot toward more focused attention on societal challenges and our ability to predict changes and study mitigation and resilience. The strategy described a number of global dynamics including climate and resource-related critical zone (CZ) impacts and emphasized the need for data integration as a significant underpinning for all of the science questions raised in the report. Organizational changes that came about as a result of the science strategy sparked a new entity called Core Science Systems, which has set as its mission the creation of a Modular Science Framework designed to seamlessly organize and integrate all data, information, and knowledge from the CZ. A part of this grand challenge is directly within the purview of the USGS mission and our science programs, while the data integration framework itself is part of a much larger global scientific cyberinfrastructure. This talk describes current research and development in pursuit of the USGS Modular Science Framework and how the work is being conducted in the context of the broader earth system sciences. Communities of practice under the banner of the Earth Science Information Partners are fostering working relationships vital to cohesion and interoperability between contributing institutions. The National Science Foundation's EarthCube and Cyberinfrastructure for the 21st Century initiatives are providing some of the necessary building blocks through foundational informatics and data science research. The U.S. Group on Earth Observations is providing leadership and coordination across agencies who operate earth observation systems. The White House Big Data Initiative is providing long term research and development vision to set the stage for sustainable, long term infrastructure across government data agencies. The end result will be a major building block of CZ science.

  13. Making a map of science: general systems theory as a conceptual framework for tertiary science education

    Gulyaev, Sergei A.; Stonyer, Heather R.

    2002-07-01

    As a result of the reductionist approach to science curricula in tertiary education, students are learning science in a fragmented way. With the purpose of providing students with tools for a more holistic understanding of science, an integrated approach based on the use of general systems theory (GST) and the concept of 'mapping' scientific knowledge (its relationships, connections and generalities) is developed. GST is used as the core methodology for understanding science and its complexity. By analogy with geographic maps, we introduce scales of educational 'science maps' - scales of integration. Three principal scales of integration can be distinguished in GST, which we consider necessary for GST to be effectively applied in education. They are (a) the scale of branches and fields of science, (b) the scale of hypotheses and theories, and (c) the scale of structures and hierarchies. Examples of each of these three scales are provided from the field of physical science. The role of the scientific community in producing accessible, and essential, maps of scientific knowledge for science education is discussed.

  14. The knowledge most worth having: Otis W. Caldwell (1869 1947) and the rise of the general science course

    NASA Astrophysics Data System (ADS)

    Heffron, John M.

    1995-07-01

    In 1860 Herbert Spencer asked the famous rhetorical question ‘What Knowledge is of Most Worth?’ The unequivocal answer was science. Giving greater attention to science and scientific knowledge would not only produce additional scientists; more important, argued Spencer, it would make better parents, better church-goers, better citizens and workers, better artists and better consumers of art. It would lead to a ‘command of fundamental processes’, ‘worthy home membership’, ‘worthy use of leisure’, ‘ethical character’ — the goals of a general education spelled out by Spencerians within the National Educational Association in 1918. Here is our puzzle, then: how are we to interpret a definition of science, one widely accepted both in Spencer's time and in our own, that comes so close descriptively to a commonsensical view of what constitutes non-science? The answer to this question lies in part in the historical relationship between science and general education, a relationship established in the opening decades of this century, when the authority of science and scientific objectivity was in the minds of most educators unimpeachable. The high school general science course, developed in its early stages by the botanist and educator, Otis W. Caldwell, was a potent symbol of this new relationship. Organized around broad, topical issues and claiming to teach the mundane truths of life, general science was more than a loose collection of facts from the various earth, biological, and physical sciences. Its many advocates viewed the new unified science course as pedagogically independent of the specialties yet central to education in general. In 1949, two years after Caldwell's death, 72 percent of the total science enrollments in the United States were in general science and biology, its closest cognate. This paper examines the rise of the general science course and its implications for the reform of secondary school science education. It concludes that

    2015-01-01

    A great deal of recent work has been devoted to the topic of biomarkers as aids to diagnosis, prognosis and treatment evaluation. Basing our work on the Ontology for General Medical Science (OGMS) and on the specifications provided by the Institute of Medicine (IOM), we propose definitions for biomarkers of various types. These definitions provide a formal representation of what biomarkers are in a way that allows us to remove certain ambiguities and inconsistencies in the documentation provided by the IOM.

  16. Sex Differences in Variability in General Intelligence: A New Look at the Old Question.

    PubMed

    Johnson, Wendy; Carothers, Andrew; Deary, Ian J

    2008-11-01

    The idea that general intelligence may be more variable in males than in females has a long history. In recent years it has been presented as a reason that there is little, if any, mean sex difference in general intelligence, yet males tend to be overrepresented at both the top and bottom ends of its overall, presumably normal, distribution. Clear analysis of the actual distribution of general intelligence based on large and appropriately population-representative samples is rare, however. Using two population-wide surveys of general intelligence in 11-year-olds in Scotland, we showed that there were substantial departures from normality in the distribution, with less variability in the higher range than in the lower. Despite mean IQ-scale scores of 100, modal scores were about 105. Even above modal level, males showed more variability than females. This is consistent with a model of the population distribution of general intelligence as a mixture of two essentially normal distributions, one reflecting normal variation in general intelligence and one refecting normal variation in effects of genetic and environmental conditions involving mental retardation. Though present at the high end of the distribution, sex differences in variability did not appear to account for sex differences in high-level achievement. PMID:26158978

  18. Unquestioned answers or unanswered questions: beliefs about science guide responses to uncertainty in climate change risk communication.

    PubMed

    Rabinovich, Anna; Morton, Thomas A

    2012-06-01

    In two experimental studies we investigated the effect of beliefs about the nature and purpose of science (classical vs. Kuhnian models of science) on responses to uncertainty in scientific messages about climate change risk. The results revealed a significant interaction between both measured (Study 1) and manipulated (Study 2) beliefs about science and the level of communicated uncertainty on willingness to act in line with the message. Specifically, messages that communicated high uncertainty were more persuasive for participants who shared an understanding of science as debate than for those who believed that science is a search for absolute truth. In addition, participants who had a concept of science as debate were more motivated by higher (rather than lower) uncertainty in climate change messages. The results suggest that achieving alignment between the general public's beliefs about science and the style of the scientific messages is crucial for successful risk communication in science. Accordingly, rather than uncertainty always undermining the effectiveness of science communication, uncertainty can enhance message effects when it fits the audience's understanding of what science is.

    NASA Astrophysics Data System (ADS)

    Tippins, Deborah J.; Hammond, Lorie; Hutchison, Charles B.

    2006-12-01

    International high school science teachers are crossing international and cultural borders to teach, raising important issues in education. In this article, we describe the cross-cultural assessment challenges that four international science teachers encountered when they migrated to teach in the United States. These included differences in grade expectations for a given quality of work, the weight given to final examinations, the assessment process, and cutoff scores for letter grades. To become proficient in their new teaching contexts, the participating teachers had to modify (or hybridize) their assessment philosophies and practices in order to conform to the expectations of their new schools. This hybridization process ushered them into what is proposed as the Pedagogical imaginary; a transitional space between the ``purity'' of their native educational conventions and that of their American schools. The implications of these findings are discussed in hopes of improving high school science teaching experiences for international science teachers.

    2012-10-01

    The broader implications of Plasma Science remains an elusive topic that the general public rarely discusses, regardless of their relevance to energy, the environment, and technology. Recently, we have looked beyond print media for methods to reach large numbers of people in creative and informative ways. These have included video, art, images, and music. For example, our submission to the ``What is a Flame?'' contest was ranked in the top 15 out of 800 submissions. Images of plasmas have won 3 out of 5 of the Princeton University ``Art of Science'' competitions. We use a plasma speaker to teach students of all ages about sound generation and plasma physics. We report on the details of each of these and future videos and animations under development.

  10. Learning by Doing: Science in a Large General Education Class

    NASA Astrophysics Data System (ADS)

    Lebofsky, Larry A.; Moore, R. W.; Lebofsky, N. R.

    2007-12-01

    Teaching science in a large (150+ students) class can be a challenge. This is especially true in a general education science class that is populated by non-science majors, athletes, and students with math phobias, as well as students with a variety of learning disabilities. To illustrate Newton's Laws, we used The Egg Fling: knocking a pie pan from under a raw egg which then falls straight down into a container of water. Newton's Laws are projected on an overhead in constant view of the students, and an ELMO is used to give a live, big-screen view to engage even those in the back of the large lecture room. Students make predictions, watch the demo, then refine or correct predictions as we discuss which laws are illustrated. The Laws are later related to students’ science fiction books and the GEMS Moons of Jupiter activity. Reading classic science fiction books allows students to see how our understanding of the universe and our technology have changed over the last 150 years, also adding a writing component to the class. Student preceptors are critical to the success of this approach, leading small group discussions that could not easily be done with the whole class. Preceptors receive training before they lead activities or discussions with groups of 10 to 15 peers. Students do live sky observations and informal measurements to track the motion and phases of the Moon against the background stars, but use technology (Heavens Above and Starry Night) to track and understand the rising and setting of the Sun and its relation to the reason for the seasons. Using a combination of live demonstrations with technology, short assessments, and student preceptors makes teaching a large group possible, effective, and fun.

    PubMed

    Friedman, Robert Marc

    2011-12-01

    Recent historical research reveals a much greater role than previously assumed for science in the polar activities of Fridtjof Nansen and Roald Amundsen. Science-based polar exploration was what first linked these two men; Amundsen's subsequent turn to sport and sensation dampened their relationship. These insights and other new perspectives about heroic period of polar exploration are being transformed by the author into a drama for stage that will have its world premier in Norway in December 2011. The play attempts to use imaginatively the art and craft of theatre to diffuse insight from historical scholarship. PMID:21962487

  14. The ability of children to generalize selected science concepts

    NASA Astrophysics Data System (ADS)

    Abdullah, Kemal Bin; Lowell, Walter E.

    The study investigated the ability of primary and elementary school subjects to generalize two science concepts, Insect and Animal with and without instruction in the form of a mental set. It also examined the effects of age, IQ, and sex on the ability of the children to generalize these concepts. Two instruments measuring the ability to generalize the concepts Insect and Animal were developed. The results indicate that of the independent variables investigated, age and mental set significantly affected the ability to generalize the concepts Insect and Animal. It was found that the younger children's concepts were least developed and with age these concepts became more developed and more conceptual in nature. The ability to use information given in a mental set was found to be a function of age. The children in this study were more able to generalize the concept Insect than the concept Animal. The results suggest that children with age and instruction axe better able to master less general concepts than more geaeral ones. In addition, the study demonstrated that children are able to improve their learning of general concepts provided a great number and variety of instances and noninstances of the concept are used in the instruction.It was also found that the younger children were more perceptually bound than the older children. The younger children were unable to overcome the pull of perceptual attractiveness that the noninstances held for them despite instruction. The results suggest that teachers of such children should be aware of the conceptual level of the content being taught to such children to ensure appropriate and meaningful learning takes place.

  15. Setting the question for inquiry: The effects of whole class vs small group on student achievement in elementary science

    NASA Astrophysics Data System (ADS)

    Cavagnetto, Andy Roy

    This study was conducted to determine the effects of two different student-centered approaches to setting the question for inquiry. The first approach (whole class) consisted of students setting a single question for inquiry after which students worked in small groups during an investigation phase of the activity with all groups exploring the same question. The second approach (small group) consisted of each group of students setting a question resulting in numerous questions being explored per class. A mixed method quasi-experimental design was utilized. Two grade five teachers from a small rural school district in the Midwestern United States participated, each teaching two sections of science (approximately 25 students per section). Results indicate three major findings. Instructional approach (whole class vs. small group) did not effect student achievement in science or language arts. Observational data indicated the actions and skills teachers utilized to implement the approaches were similar. Specifically, the pedagogical skills of dialogical interaction (which was found to be influenced by teacher level of control of learning and teacher content knowledge) and effective rather than efficient use of time were identified as key factors in teachers' progression toward a student-centered, teacher-managed instructional approach. Unit exams along with qualitative and quantitative teacher observation data indicated that these factors do have an impact on student achievement. Specifically increased dialogical interaction in the forms of greater student voice, and increased cognitive demands placed on students by embedding and emphasizing science argument within the student inquiry corresponded to positive gains in student achievement. Additionally, teacher's perception of student abilities was also found to influence professional growth. Finally, allowing students to set the questions for inquiry and design the experiments impact the classroom environment as teacher

    Rice*, Diana C.

    2005-09-01

    In this descriptive study, the science subject matter knowledge of preservice and inservice elementary teachers was examined and compared. Over an eight-year period, answers to 13 science questions, including 10 from the US National Science Foundation's Survey of Public Attitudes Toward and Understanding of Science and Technology, were collected from a total of 414 preservice and 67 inservice teachers during first-day discussions in elementary science methods courses. Both groups outperformed average citizens on the 10 survey questions. However, three other questions used to introduce discussion of why students may find learning science difficult revealed lack of conceptual understanding of basic physical and biological phenomena commonly found in most elementary science curricula. Results and implications are discussed in the context of increasing expectations for subject matter competence demanded of ‘highly qualified teachers’ under provisions of the 2001 US Elementary and Secondary Education Act (‘No Child Left Behind Act’).

  4. Is victim identity in genocide a question of science or law? The scientific perspective, with special reference to Darfur.

    PubMed

    Komar, Debra

    2008-09-01

    In genocide, victims must represent an ethnic, racial, religious or national group. But is victim identity a question of science or law? Must victims be a socially recognized group or can group identity exist solely in the mind of the perpetrator? This question is relevant to the on-going crisis in Darfur. The "Arab-on-African" violence depicted in the media encompasses identities not shared by Darfurians. This study details an evaluation of victim identity in Darfur, based on field research and literature review. Darfurians are defined by subsistence strategy and economic groups are not protected under genocide law. Whether Darfur is genocide depends on whether victims must conform to scientific group classifications or need only be defined by their relationship to the perpetrators. PMID:18953803

  5. Methodological troubles as problems and phenomena: ethnomethodology and the question of 'method' in the social sciences.

    PubMed

    Greiffenhagen, Christian; Mair, Michael; Sharrock, Wes

    2015-09-01

    Across the disciplinary frontiers of the social sciences, studies by social scientists treating their own investigative practices as sites of empirical inquiry have proliferated. Most of these studies have been retrospective, historical, after-the-fact reconstructions of social scientific studies mixing interview data with the (predominantly textual) traces that investigations leave behind. Observational studies of in situ work in social science research are, however, relatively scarce. Ethnomethodology was an early and prominent attempt to treat social science methodology as a topic for sociological investigations and, in this paper, we draw out what we see as its distinctive contribution: namely, a focus on troubles as features of the in situ, practical accomplishment of method, in particular, the way that research outcomes are shaped by the local practices of investigators in response to the troubles they encounter along the way. Based on two case studies, we distinguish methodological troubles as problems and methodological troubles as phenomena to be studied, and suggest the latter orientation provides an alternate starting point for addressing social scientists' investigative practices.

    After assessing the state of current understanding of the planetological characteristics of the moon, attention is given to numerous questions that have arisen about the history of the moon and to prospective methods for their investigation through lunar exploration. One such exploratory mission will be that of the unmanned Lunar Geoscience Observer; the greatest prospects for important discoveries, however, are foreseen in manned lunar exploration. More sophisticated instruments and preliminary analyses are noted to be possible in manned exploration, although the possibility of contamination of samples is greater.

  19. Shunning the Bird's Eye View: General Science in the Schools of Ontario and Quebec

    NASA Astrophysics Data System (ADS)

    Hoffman, Michelle

    2013-04-01

    This paper considers the adoption of general science courses in two Canadian provinces, Ontario and Quebec, during the 1930s. In Ontario, a few science teachers had followed the early general science movements in the United States and Britain with interest. During the 1930s, several developments made the cross-disciplinary, applied thrust of general science particularly appealing to Ontario educationists. These developments included a new demand for vocational education, renewed reservations about pedagogical rationales based on transfer of training, and a growing professional divide between high school science teachers and university scientists. Around the same time, scientists in the Quebec's French-language universities were engaged in a concerted campaign to expand the place of science in the province's francophone secondary schools. The province's prestigious classical colleges, which were the scientists' principal target for reform, privileged an inductive view of science that had little in common with the applied, cross-disciplinary emphasis of the general science courses gaining support in English-speaking school systems. In 1934, however, a popular American general science textbook was adopted in a workers' cooperative devoted to adult education. Comparing the fate of general science within these two education systems draws attention to the fact that general science made inroads in francophone Quebec but had little influence in public and private schools. In light of the growing support general science enjoyed elsewhere, we are led to explore why general science met with little overt interest by Quebec scientists pushing for school science reform during the 1930s.

  20. The Difficult and The Cryptic: Next Questions For Antarctic Earth Science from a Remote Sensing Perspective

    NASA Astrophysics Data System (ADS)

    Wagner, T. P.; Larour, E. Y.; Webb, C. E.

    2015-12-01

    A system-level approach to Antarctic science may be on the horizon. This talk will outline some of the required activities, and discuss ways the polar science community can marshal resources to achieve them. Advances in remote sensing, earth science, and modeling have set the stage for leaps in our understanding of the ice sheet and sea ice, and their connections to the atmosphere, ocean, and solid earth. Two seemingly opposed activities are now needed to capitalize on these advances: intense, challenging field campaigns—especially at the ice-ocean interface—and routine in situ measurements across the region to improve our knowledge of cryptic, important phenomena such as surface mass balance. Satellite observations have revealed significant on-going changes in the Antarctic cryosphere, including increases in sea-ice cover, outlet-glacier retreat, sub-glacial water activity, and ice-shelf fracture. The processes that drive these changes, however, are partly understood at best and field campaigns and routine measurements throughout the region are required. Remote sensing observations have offered a range of new insights into the ice-ocean interface, and models of the ice sheet and ocean have dramatically improved. But in situ data to constrain them is sorely lacking. Intense field campaigns with installed instrumentation are needed. Similarly, knowledge of the surface mass balance of land and sea ice is also needed to constrain ice sheet mass balance and sea ice evolution. Atmospheric reanalyses of satellite data may help characterize these phenomena by providing a comprehensive view of the climate system. But they require validation data, such as precipitation rates, and improved process knowledge, such as improved characterizations of clouds and blowing snow. These require in situ measurements, especially routine measurements at challenging locations throughout the region.

  2. Integrating K-W-L Prompts into Science Journal Writing: Can Simple Question Scaffolding Increase Student Content Knowledge?

    NASA Astrophysics Data System (ADS)

    Wagner, Brandon Joel

    Writing-to-learn strategies have been administered in the past to enrich student learning. The purpose of this study was to see if K-W-L prompts in science journal writing could benefit student content knowledge within biology. Two high school biology classes were provided with learning journals. The journals given to the students during the treatment unit were provided with K-W-L question prompts to guide student learning while during the comparison unit students were given an open ended writing assignment. Pre and posttests were administered to determine student-learning gains. Student motivations and opinions of the treatment were collected through student interviews. The combined results were used to determine to what extent could K-W-L prompts in science journal writing influence comprehension of content knowledge. This study found there to be no difference in student learning gains when utilizing the K-W-L literacy strategy versus another free-writing activity. When scored, student K-W-Ls total scores did correlate to student success on unit tests. This opens up the potential for K-W-Ls to serve as an adequate tool for formative assessment. Here the K-W-L could be expanded to enrich student question asking, potentially aid students learning English, and potentially be used by students without teacher scaffolding.

  3. Transnational Nationalism and Idealistic Science: The Alcohol Question between the Wars

    PubMed Central

    Edman, Johan

    2016-01-01

    This article studies the interwar international conferences on the alcohol problem. How did they view the alcohol problem and its causes; what were the consequences for the individual and the society as a whole; and which solutions merited discussion? The first post-war conferences enjoyed an optimistic and internationalistic atmosphere, added to by American prohibition, which had given the temperance movement plenty to be hopeful about. But when the 1920s turned to the 1930s, the conferences were transformed into arenas for national solutions and into outright propaganda pieces. The responses to the alcohol problem debated in the interwar conferences built on a combination of scientifically masked ideological conviction and ideologically inspired passion for science. The apparently neutral ethics of such thinking was manifested in various radical measures to combat alcohol abuse. PMID:27482147

    2016-01-01

    Researchers have yet to account for the potentially unique experiences of emerging adults who are in or seeking to be in a relationship with a same-sex romantic partner. This paper articulates an agenda for research focused on better understanding and addressing the health and well-being of emerging adults in or pursuing same-sex romantic relationships. We provide a general summary of what is known about health and well-being in same-sex relationships, followed by an overview of the current and changing social climate surrounding same-sex relationships. We point out how recent historical changes present sexual minority emerging adults with unique relational benefits and challenges that have not been examined within the social and health sciences. We conclude by proposing a set of research questions to help develop knowledge needed to improve the health and well-being of emerging adults in or pursuing same-sex relationships.

    2007-08-01

    It is the general conclusion of all national programs that the development of high-performance reduced-activation structural materials is essential for the successful development of fusion power. In this paper, the experience gleaned from previous programs to develop materials for high temperature structural applications is used to identify and discuss some of the most critical issues that must be addressed in the development of candidate materials for fusion structural applications. Critical issues discussed include radiation-induced solute segregation and implications on phase stability in the development of high-performance alloys/ceramics; the effects of very large amounts of helium on mechanical properties and the implications for alloy design/development; development of high temperature design methodology and incorporation of radiation effects into this methodology; the effects of radiation damage on flow localization, and the implications and approach to control the phenomena; and considerations of mass transfer and corrosion in complex fusion systems.

  7. Boise Hydrogeophysical Research Site: Field-Scale Test Facility for Addressing Fundamental Questions of Environmental Science

    NASA Astrophysics Data System (ADS)

    Barrash, W.; Routh, P. S.

    2006-12-01

    The Boise Hydrogeophysical Research Site (BHRS) is a research wellfield or field-scale test facility developed in a shallow, coarse, fluvial aquifer with the objectives of supporting (a) development of cost-effective, non- invasive methods for quantitative characterization and imaging methods in heterogeneous aquifers using hydrologic and geophysical techniques; (b) examination of fundamental relationships and processes at multiple scales; (c) testing theories and models for groundwater flow and solute transport; and (d) educating and training the next generation of professionals in multidisciplinary subsurface science and engineering. The design of the wells and the wellfield provide for a wide range of single-well, cross-hole, multiwell and multilevel hydrologic, geophysical, and combined hydrologic-geophysical experiments. Efforts have been focused largely on (a) establishing the 3D distributions of geologic, hydrologic, and geophysical parameters which can then be used as the basis for testing methods to jointly invert hard and soft data to return the "known" 3D K distribution and (b) developing subsurface measurement and imaging methods including static and time-lapse tomographic imaging methods. From this work we have developed a good understanding of the hydrostratigraphic framework of the BHRS as a hierarchical system which includes layers and lenses; this framework is recognized with geologic, hydrologic, radar, seismic, and EM methods and tracer tests. Work to date has been conducted by Boise State University with some collaboration and exchange with researchers and students from other institutions. At this point the BHRS is functioning well as a field-scale control volume and test cell in a multiscale heterogeneous aquifer so there is an opportunity to increase the range of both collaborative participation and research activities at the BHRS. In this regard, opportunities exist to investigate and monitor process and property variation in time and space

Forcing the students to use their ability to estimate, giving answers in terms of order-of-magnitude, is not only a challenge for a competition, but a teaching strategy to use in the classroom to develop self-confidence and the ability to analyze answers as to whether or not they make sense, as opposed to relying on the "precision" of a calculator value.

  15. Feature description with SIFT, SURF, BRIEF, BRISK, or FREAK? A general question answered for bone age assessment.

    PubMed

    Kashif, Muhammad; Deserno, Thomas M; Haak, Daniel; Jonas, Stephan

    2016-01-01

    Solving problems in medical image processing is either generic (being applicable to many problems) or specific (optimized for a certain task). For example, bone age assessment (BAA) on hand radiographs is a frequent but cumbersome task for radiologists. For this problem, many specific solutions have been proposed. However, general-purpose feature descriptors are used in many computer vision applications. Hence, the aim of this study is (i) to compare the five leading keypoint descriptors on BAA, and, in doing so, (ii) presenting a generic approach for a specific task. Two methods for keypoint selection were applied: sparse and dense feature points. For each type, SIFT, SURF, BRIEF, BRISK, and FREAK feature descriptors were extracted within the epiphyseal regions of interest (eROI). Classification was performed using a support vector machine. Reference data (1101 radiographs) of the University of Southern California was used for 5-fold cross-validation. The data was grouped into 30 classes representing the bone age range of 0-18 years. With a mean error of 0.605 years, dense SIFT gave best results and outperforms all published methods. The accuracy was 98.36% within the range of 2 years. Dense SIFT represents a generic method for a specific question. PMID:26623943

  16. Can Science Education Research Give an Answer to Questions posed by History of Science and Technology? The Case of Steam Engine's Measurement

    NASA Astrophysics Data System (ADS)

    Kanderakis, Nikos E.

    2009-09-01

    According to the principle of virtual velocities, if on a simple machine in equilibrium we suppose a slight virtual movement, then the ratio of weights or forces equals the inverse ratio of velocities or displacements. The product of the weight raised or force applied multiplied by the height or displacement plays a central role there. British engineers used the same product in the eighteenth century in order to measure steam engines’ effectiveness. The question is whether this measure was obviously empirical or had its origin in theory of mechanics and particularly in the principle of virtual velocities. According to science education research, this measure is not likely to have arisen intuitively and most probably could not have been formulated without any acquaintance with theory of mechanics.

    Harolds, Jay A

    2014-07-01

    The type and caliber of the questions asked by a job hunter is one of the ways an interviewer will evaluate the candidate. Questions that show poor preparation should not be asked, such as failure to read what the employer sent to the job seeker or not doing elementary research on the practice, the organization, or the community. Asking about insignificant details also is not helpful. Not having any good questions to ask is a negative in an interview. This article discusses many possible important questions for the applicant to ask during an interview. PMID:24873801

    Astrophysics is one branch of science which excites the imagination of the general public. Pioneer science popularizers like George Gamow and Fred Hoyle wrote on different aspects of astrophysics. However, of late, we see a trend which I find disturbing. While it has become extremely fashionable to write popular science books on cosmology, other areas of astrophysics are grossly neglected.

  2. [General practitioners' commitment to treating excessive alcohol consumption: A question of role security in treating affected patients?].

    PubMed

    2016-01-01

    Only a few general practitioners (GPs) are committed to screen their patients for alcohol consumption and, in case of excessive alcohol consumption conduct by a brief intervention according to WHO recommendations. Apart from inadequate compensation and work load, another barrier identified by the GPs was their uncertainty about how to deal with affected patients. Most German universities presently spend no more than 90minutes lecture time on addiction medicine teaching. Our research aims to investigate the question whether medical studies and advanced medical education increases the role security of medical students and physicians and their commitment to implementing alcohol screening and brief intervention. Moreover, we will explore whether lack of therapeutic commitment can be related to lack of role security. Questionnaires were administered to pre-clinical and clinical medical students as well as senior house officers. Role security and therapeutic commitment of students and senior house officers were assessed using the Alcohol and Alcohol Problems Questionnaire (SAAPPQ) subscales "Role Security" and "Therapeutic Commitment". Analysis was based on 367 questionnaires. As expected, senior house officers reported more Role Security than clinical medical students who showed a higher level of Role Security than pre-clinical medical students. No differences could be found for Therapeutic Commitment. An association between Role Security and Therapeutic Commitment was only revealed for clinical medical students. Medical studies and advanced medical education can increase students' and senior house officers' Role Security to treat patients with excessive alcohol consumption, but not Therapeutic Commitment. Moreover, no association between Role Security and Therapeutic Commitment could be found for senior house officers. Hence, it may be assumed that educational activities aiming to increase Role Security do not promote the development of motivational aspects such as

  8. On the Meaning of Element in the Science of Italic Tradition, the Question of Physical Objectivity (and/or Physical Meaning) and Quantum Mechanics

    NASA Astrophysics Data System (ADS)

    Boscarino, Giuseppe

    2006-06-01

    It is questioned: Is quantum mechanics a new science or a new (or rather old) philosophy of physical science? It is shown that Einstein's attempt in his article of 1935 to bring the concept of "element" from the classical (we call it Italic) philosophical-epistemological tradition, which goes under the names of Pythagoras Parmenides, Democritus, and Newton, into quantum mechanical theory is unclear, inadequate and contradictory.

  14. Design and Assessment of a General Science STEM Course with a Blended Learning Approach

    NASA Astrophysics Data System (ADS)

    Courtier, A. M.; Liu, J. C.; St John, K. K.

    2015-12-01

    Blended learning, a combination of classroom- and computer-mediated teaching and learning, is becoming prominent in higher education, and structured assessment is necessary to determine pedagogical costs and benefits. Assessment of a blended general education science class at James Madison University used a mixed-method causal-comparative design: in Spring 2014, two classes with identical content and similar groups of non-science majors were taught by the same instructor in either blended or full face-to-face formats. The learning experience of 160 students in the two classes was compared based on course and exam grades, classroom observation, and student survey results. Student acquisition of content in both classes was measured with pre-post tests using published concept inventories, and surveys, quizzes, and grade reports in the Blackboard learning management system were additionally used for data collection. Exams were identical between the two sections, and exam questions were validated in advance by a faculty member who teaches other sections of the same course. A course experience questionnaire was administered to measure students' personal experiences in both classes, addressing dimensions of good teaching, clear goals and standards, generic skills, appropriate assessment and workload, and emphasis on independence. Using a STEM classroom observation checklist, two researchers conducted in-class observations for four 75-minute face-to-face meetings with similar content focus in both classes, which allowed assessment of student engagement and participation. We will present details of the course design and research plan, as well as assessment results from both quantitative and qualitative analysis. The preliminary findings include slightly higher average grade distribution and more ready responses to in-class activities in the blended class.

  1. Examining Teachers' Instructional Moves Aimed at Developing Students' Ideas and Questions in Learner-Centered Science Classrooms

    NASA Astrophysics Data System (ADS)

    Harris, Christopher J.; Phillips, Rachel S.; Penuel, William R.

    2012-11-01

    Prior research has shown that orchestrating scientific discourse in classrooms is difficult and takes a great deal of effort on the part of teachers. In this study, we examined teachers' instructional moves to elicit and develop students' ideas and questions as they orchestrated discourse with their fifth grade students during a learner-centered environmental biology unit. The unit materials included features meant to support teachers in eliciting and working with students' ideas and questions as a source for student-led investigations. We present three contrasting cases of teachers to highlight evidence that shows teachers' differing strategies for eliciting students' ideas and questions, and for developing their ideas, questions and questioning skills. Results from our cross case analysis provide insight into the ways in which teachers' enactments enabled them to work with students' ideas and questions to help advance learning. Consistent with other studies, we found that teachers could readily elicit ideas and questions but experienced challenges in helping students develop them. Findings suggest a need for more specified supports, such as specific discourse strategies, to help teachers attend to student thinking. We explore implications for curricular tools and discuss a need for more examples of effective discourse moves for use by teachers in orchestrating scientific discourse.

  2. Generalizations and kinds in natural science: the case of species.

    PubMed

    Reydon, Thomas A C

    2006-06-01

    Species in biology are traditionally perceived as kinds of organisms about which explanatory and predictive generalizations can be made, and biologists commonly use species in this manner. This perception of species is, however, in stark contrast with the currently accepted view that species are not kinds or classes at all, but individuals. In this paper I investigate the conditions under which the two views of species might be held simultaneously. Specifically, I ask whether upon acceptance of an ontology of species as diachronic segments of the tree of life (this is one version of the species as individuals ontology) species can perform the epistemic role of kinds of organisms to which explanatory and predictive generalizations apply. I show that, for species-level segments of the tree of life, several requirements have to be met before the performance of this epistemic role is possible, and I argue that these requirements can be met by defining species according to the Composite Species Concept proposed by Kornet and McAllister in the 1990s.

  5. Teacher Roles of Questioning in Early Elementary Science Classrooms: A Framework Promoting Student Cognitive Complexities in Argumentation

    NASA Astrophysics Data System (ADS)

    Chen, Ying-Chih; Hand, Brian; Norton-Meier, Lori

    2016-01-01

    The purpose of this study was to investigate the various roles that early elementary teachers adopt when questioning, to scaffold dialogic interaction and students' cognitive responses for argumentative practices over time. Teacher questioning is a pivotal contributing factor that shapes the role teachers play in promoting dialogic interaction in argumentative practice and that different roles serve different functions for promoting students' conceptual understanding. The multiple-case study was designed as a follow-up study after a 4-year professional development program that emphasized an argument-based inquiry approach. Data sources included 30 lessons focusing on whole class discussion from three early elementary teachers' classes. Data were analyzed through two approaches: (1) constant comparative method and (2) enumerative approach. This study conceptualized four critical roles of teacher questioning—dispenser, moderator, coach, and participant—in light of the ownership of ideas and activities. The findings revealed two salient changes in teachers' use of questions and the relationships between teachers' question-asking and students' cognitive responses: (1) teachers increasingly used multiple roles in establishing argumentative discourse as they persistently implemented an argument-based inquiry approach, and (2) as teachers used multiple roles in establishing patterns of questioning and framing classroom interactions, higher levels of student cognitive responses were promoted. This study suggests that an essential component of teacher professional development should include the study of the various roles that teachers can play when questioning for establishing dialogic interaction in argumentation and that this development should consist of ongoing training with systematic support.

  6. Debates of science vs. religion in undergraduate general education cosmology courses

    NASA Astrophysics Data System (ADS)

    Lopez-Aleman, Ramon

    2015-04-01

    Recent advances in theoretical physics such as the discovery of the Higgs boson or the BICEP2 data supporting inflation can be part of the general science curriculum of non-science majors in a cosmology course designed as part of the General Education component. Yet to be a truly interdisciplinary experience one must deal with the religious background and faith of most of our students. Religious faith seems to be important in their lives, but the philosophical outlook of sciences like cosmology or evolutionary biology is one in which God is an unnecessary component in explaining the nature and origin of the universe. We will review recent advances in cosmology and suggestions on how to establish a respectful and intelligent science vs. religion debate in a transdisciplinary general education setting.

  10. Japanese representation in leading general medicine and basic science journals: a comparison of two decades.

    PubMed

    2013-01-01

    During 1991-2000, Japan contribution to the top general medicine journals was very small although the contribution to the top basic science journals was sizeable. However, it has not been examined whether the contribution to the top general medicine and basic science journals has changed during the last decade (2001-2010). The objective of this study was to compare Japan representation in high-impact general medicine and basic science journals between the years 1991-2000 and 2001-2010. We used PubMed database to examine the frequency of articles originated from Japan and published in 7 high-impact general medicine and 6 high-impact basic science journals. Several Boolean operators were used to connect name of the journal, year of publication and corresponding authors' affiliation in Japan. Compared to the 1991-2000 decade, Japan contribution to the top general medicine journals did not increase over the 2001-2010 period (0.66% vs. 0.74%, P = 0.255). However, compared to the same period, its contribution to the top basic science journals increased during 2001-2010 (2.51% vs. 3.60%, P < 0.001). Japan representation in basic science journals showed an upward trend over the 1991-2000 period (P < 0.001) but remained flat during 2001-2010 (P = 0.177). In contrast, the trend of Japan representation in general medicine journals remained flat both during 1991-2000 (P = 0.273) and 2001-2010 (P = 0.073). Overall, Japan contribution to the top general medicine journals has remained small and unchanged over the last two decades. However, top basic science journals had higher Japan representation during 2001-2010 compared to 1991-2000. PMID:24189990

  11. Science in the General Educational Development (GED) curriculum: Analyzing the science portion of GED programs and exploring adult students' attitudes toward science

    NASA Astrophysics Data System (ADS)

    Hariharan, Joya Reena

    The General Educational Development (GED) tests enable people to earn a high school equivalency diploma and help them to qualify for more jobs and opportunities. Apart from this main goal, GED courses aim at enabling adults to improve the condition of their lives and to cope with a changing society. In today's world, science and technology play an exceedingly important role in helping people better their lives and in promoting the national goals of informed citizenship. Despite the current efforts in the field of secondary science education directed towards scientific literacy and the concept of "Science for all Americans", the literature does not reflect any corresponding efforts in the field of adult education. Science education research appears to have neglected a population that could possibly benefit from it. The purpose of this study is to explore: the science component of GED programs, significant features of the science portion of GED curricula and GED science materials, and adult learners' attitudes toward various aspects of science. Data collection methods included interviews with GED students and instructors, content analysis of relevant materials, and classroom observations. Data indicate that the students in general feel that the science they learn should be relevant to their lives and have direct applications in everyday life. Student understanding of science and interest in it appears to be contingent to their perceiving it as relevant to their lives and to society. Findings indicate that the instructional approaches used in GED programs influence students' perceptions about the relevance of science. Students in sites that use strategies such as group discussions and field trips appear to be more aware of science in the world around them and more enthusiastic about increasing this awareness. However, the dominant strategy in most GED programs is individual reading. The educational strategies used in GED programs generally focus on developing reading

    1994-08-01

    Despite the remarkable progress in the past decades in understanding our Universe, we particle physicists have failed to communicate the wonder, excitement, and beauty of these discoveries to the general public. I am sure all agree there is a need, if our support from public funds is to continue at anywhere approximating the present level, for us collectively to educate and inform the general public of what we are doing and why. Informal science education and especially science and technology centers can play an important role in efforts to raise public awareness of particle physics in particular and of basic research in general. Science Centers are a natural avenue for particle physicists to use to communicate with and gain support from the general public.

  13. On extracting design principles from biology: I. Method-General answers to high-level design questions for bioinspired robots.

    PubMed

    Haberland, M; Kim, S

    2015-01-01

    When millions of years of evolution suggest a particular design solution, we may be tempted to abandon traditional design methods and copy the biological example. However, biological solutions do not often translate directly into the engineering domain, and even when they do, copying eliminates the opportunity to improve. A better approach is to extract design principles relevant to the task of interest, incorporate them in engineering designs, and vet these candidates against others. This paper presents the first general framework for determining whether biologically inspired relationships between design input variables and output objectives and constraints are applicable to a variety of engineering systems. Using optimization and statistics to generalize the results beyond a particular system, the framework overcomes shortcomings observed of ad hoc methods, particularly those used in the challenging study of legged locomotion. The utility of the framework is demonstrated in a case study of the relative running efficiency of rotary-kneed and telescoping-legged robots. PMID:25643176

  14. Learning to Question: The Roles of Multiple Hypotheses, Successive Approximations, Balloons and Toilet Paper in University Science Programs of Southwestern Amazonia

    NASA Astrophysics Data System (ADS)

    Brown, I. Foster

    2008-06-01

    Learning to question is essential for determining pathways of conservation and development in southwestern Amazonia during a time of rapid global environmental change. Teaching such an approach in graduate science programs in regional universities can be done using play-acting and simulation exercises. Multiple working hypotheses help students learn to question their own research results and expert witnesses. The method of successive approximations enables students to question the results of complex calculations, such as estimates of forest biomass. Balloons and rolls of toilet paper provide means of questioning two-dimensional representations of a three-dimensional Earth and the value of pi. Generation of systematic errors can illustrate the pitfalls of blind acceptance of data. While learning to question is essential, it is insufficient by itself; students must also learn how to be solutionologists in order to satisfy societal demands for solutions to environmental problems. A little irreverence can be an excellent didactic tool for helping students develop the skills necessary to lead conservation and development efforts in the region.

    2015-01-01

    Despite its pervasive use, the clinical efficacy of platelet-rich plasma (PRP) therapy and the different mechanisms of action have yet to be established. This overview of the literature is focused on the role of PRP in bone, tendon, cartilage, and ligament tissue regeneration considering basic science literature deriving from in vitro and in vivo studies. Although this work provides evidence that numerous preclinical studies published within the last 10 years showed promising results concerning the application of PRP, many key questions remain unanswered and controversial results have arisen. Additional preclinical studies are needed to define the dosing, timing, and frequency of PRP injections, different techniques for delivery and location of delivery, optimal physiologic conditions for injections, and the concomitant use of recombinant proteins, cytokines, additional growth factors, biological scaffolds, and stems cells to develop optimal treatment protocols that can effectively treat various musculoskeletal conditions.

  16. Using the science writing heuristic approach as a tool for assessing and promoting students' conceptual understanding and perceptions in the general chemistry laboratory

    NASA Astrophysics Data System (ADS)

    Mohammad, Elham Ghazi

    This thesis reports on a study that examined the impact of implementing SWH (inquiry-based approach) in a general chemistry lab on non-science-major students' understanding of chemistry concepts and students' perceptions toward writing in science and implementing SWH. This study was conducted in a large university in the Midwest of the United States in a college freshman chemistry laboratory for non-science-major students. The research framework is presented including the following: the qualitative research design with the observation as data collection method for this design and the criteria for teacher level of implementation and the ranking mechanism; and the quantitative research design with data collection and analysis methods including pre- and post-conceptual exams, lecture question, open-ended surveys. This research was based on a quasi-experimental mixed-method design a focus on student performance on higher order conceptual questions, and open-ended survey at the end of semester about their perception toward writing to learn ad implementing SWH. Results from the qualitative and quantitative component indicated that implementing SWH approach has notably enhanced both male and female conceptual understanding and perception toward chemistry and implementing SWH. It is known that there is gender gap in science, where female have lower perception and self confident toward science. Interestingly, my findings have showed that implementing SWH helped closing the gap between male and female who started the semester with a statistically significant lower level of conceptual understanding of chemistry concepts among females than males.

    Self-reflection is a tool of instruction that has been used in the science classroom. Research has shown great promise in using video as a learning tool in the classroom. However, the integration of self-reflective practice using video in the general chemistry laboratory to help students develop process skills has not been done. Immediate video feedback and direct instruction were employed in a general chemistry laboratory course to improve students' mastery and understanding of basic and advanced process skills. Qualitative results and statistical analysis of quantitative data proved that self-reflection significantly helped students develop basic and advanced process skills, yet did not seem to influence the general understanding of the science content.

    The curriculum of the Faculty of Medicine and Health Sciences (FMHS) is designed particularly to cater for the health needs of the State of Sarawak, Malaysia. The framework of the curriculum is built on four strands: biological knowledge, clinical skills, behavioural and population aspects. The training is community based and a graduate of FMHS is expected to possess the ability to deal with many ethnic groups with different cultures and beliefs; expertise in tropical infectious diseases; skills to deal with emergencies such as snakebite and near drowning; qualities of an administrator, problem-solver and community leader; and proficiency in information and communication technology. The content of the curriculum strives for commitment to lifelong learning and professional values. The FMHS has adopted a 'mixed economy' of education strategies and a 'mixed menu approach' to test a wide range of curriculum outcomes. The FMHS fosters intellectual and academic pursuits, encourages friendliness and a sense of social responsibility and businesslike efficiency. PMID:12623455

    2012-12-01

    The successes of NASA rovers on Mars and new remote sensing imagery at unprecedented resolution can awaken students to the valuable application of Earth analogs to understand Mars processes and the possibilities of extraterrestrial life. Mars For Earthlings (MFE) modules and curriculum are designed as general science content introducing a pedagogical approach of integrating Earth science principles and Mars imagery. The content can be easily imported into existing or new general education courses. MFE learning modules introduce students to Google Mars and JMARS software packages and encourage Mars imagery analysis to predict habitable environments on Mars drawing on our knowledge of extreme environments on Earth. "Mars Mission" projects help students develop teamwork and presentation skills. Topic-oriented module examples include: Remote Sensing Mars, Olympus Mons and Igneous Rocks, Surface Sculpting Forces, and Extremophiles. The learning modules package imagery, video, lab, and in-class activities for each topic and are available online for faculty to adapt or adopt in courses either individually or collectively. A piloted MFE course attracted a wide range of non-majors to non-degree seeking senior citizens. Measurable outcomes of the piloted MFE curriculum were: heightened enthusiasm for science, awareness of NASA programs, application of Earth science principles, and increased science literacy to help students develop opinions of current issues (e.g., astrobiology or related government-funded research). Earth and Mars analog examples can attract and engage future STEM students as the next generation of earth, planetary, and astrobiology scientists.

  1. Podcasting as an Effective Medium for Direct Science Communication and Outreach to the General Public

    NASA Astrophysics Data System (ADS)

    Haupt, R. J.; Padilla, A. J.; Wheatley, P.; Barnhart, C. J.

    2015-12-01

    A podcast is an audio program distributed online typically freely available through an RSS feed (essentially an on-demand internet radio show). This medium has grown steadily in listenership and popularity since its inception in the early 2000s, especially thanks to popular distribution platforms such as iTunes, and web-enabled listening devices (i.e. smart phones). In terms of science reporting, many high impact journals now produce podcasts to supplement their publications (e.g. Nature, Science, etc.). However, smaller and/or more specialized journals often can't afford to promote their content via podcasts, thus limiting their authors to rely on traditional media and press releases supplied by their colleges and universities. This is where independent or unaffiliated podcasts can fill an open niche: providing a platform for scientists to discuss their research in their own words aimed at a general audience. Traditional press releases often follow a similar pattern, and many science news outlets essentially report the press releases verbatim with little additional content or reporting from primary sources. Podcasts suffer from no such restrictions, and they can be as long and in-depth as the subject matter necessitates. Furthermore, many news outlets no longer employ dedicated science reporters. Science is covered, if at all, by reporters without specialized scientific knowledge or training. This deficit leads to a much higher potential for science news stories to be incorrectly reported, or misinterpreted by the general public. A podcast allows a lab group or department the opportunity to edit the content for brevity and clarity, affording scientists a better chance of getting their research presented to the public in an accurate and representative way. Finally, podcasts allow the public to hear the voice of the scientist, humanizing the hard work they do, and potentially positively influencing the way the public reacts to science as a discipline.

  2. General chemistry students' understanding of climate science principles relating to chemistry

    2012-12-01

    As part of the NSF funded Visualizing the Chemistry of Climate Science project, we are developing the chemistry of climate science inventory for use in general chemistry courses. The U.S. Climate Change Science Program (CCSP), which integrates federal research on climate and global change, has set out a climate literacy framework, Climate Literacy: the Essential Principles of Climate Science (US Climate Change Science Program, 2009). Developed by collaboration among NOAA, NASA, AAAS, and a distinguished group of scientists and educators, this Framework defines a set of essential principles and scientific thinking skills that a climate literate person should understand. We have based our interview protocol on misconceptions identified in the research literature and the essential principles of climate change outlined in the CCSP document that pertain to chemistry. We have interviewed 24 undergraduates to elicit their understanding of the Earth's energy system, global warming, climate change, greenhouse gases, climate, and weather. Our analysis and findings indicate that the fundamental science necessary to understand the Earth's energy system and climate change are not well understood by the undergraduates in this sample. Details of the interviews, analysis, and synthesis of findings will be shared.

  3. An Analysis of Metaphors Used by Students to Describe Energy in an Interdisciplinary General Science Course

    NASA Astrophysics Data System (ADS)

    Lancor, Rachael

    2015-04-01

    The meaning of the term energy varies widely in scientific and colloquial discourse. Teasing apart the different connotations of the term can be especially challenging for non-science majors. In this study, undergraduate students taking an interdisciplinary, general science course (n = 49) were asked to explain the role of energy in five contexts: radiation, transportation, generating electricity, earthquakes, and the big bang theory. The responses were qualitatively analyzed under the framework of conceptual metaphor theory. This study presents evidence that non-science major students spontaneously use metaphorical language that is consistent with the conceptual metaphors of energy previously identified in the discourse of students in introductory physics, biology, and chemistry courses. Furthermore, most students used multiple coherent metaphors to explain the role of energy in these complex topics. This demonstrates that these conceptual metaphors for energy have broader applicability than just traditional scientific contexts. Implications for this work as a formative assessment tool in instruction will also be discussed.

  7. The role of e-Infrastructures supporting Solar System science within general research environments

    NASA Astrophysics Data System (ADS)

    Bentley, R. D.

    2012-09-01

    Many aspects of Solar System science are related with phenomena observed on the Sun subsequently causing effects in other parts of the Solar System; similarly, effects that originate in heliopshere or the near planetary environments can have impacts low down in planetary atmospheres. However, combining and comparing observations from the different domains is more difficult that it should be, partly because the communities have evolved independently without any consideration of the need for interoperability. A number of e-Infrastructures have been established to support the analysis in different aspect of science within the Solar System - some have been funded under FP7 including Europlanet RI and HELIO. Now that the Research Infrastructures are reaching maturity it is important to examine how they might work better together and be combined to support new types of science. The infrastructure established by HELIO follows a service oriented architecture where required capabilities are implemented as independent services that cam be combined as needed. If the capabilities of other infrastructures can be made available in a similar way then it is possible to consider them all as components in a larger and more general collaborative research environment that can be used to address science use cases that were previously not possible. We discuss how this might be achieved and describe some of the ideas being developed under the Coordination Action for the integration of Solar System Infrastructure and Science (CASSIS).

  8. Value Added: History of Physics in a ``Science, Technology, and Society'' General Education Undergraduate Course

    Neuenschwander, Dwight

    2016-03-01

    In thirty years of teaching a capstone ``Science, Technology, and Society'' course to undergraduate students of all majors, I have found that, upon entering STS, to most of them the Manhattan Project seems about as remote as the Civil War; few can describe the difference between nuclear and large non-nuclear weapons. With similar lack of awareness, many students seem to think the Big Bang was dreamed up by science sorcerers. One might suppose that a basic mental picture of weapons that held entire populations hostage should be part of informed citizenship. One might also suppose that questions about origins, as they are put to nature through evidence-based reasoning, should be integral to a culture's identity. Over the years I have found the history of physics to be an effective tool for bringing such subjects to life for STS students. Upon hearing some of the history behind (for example) nuclear weapons and big bang cosmology, these students can better imagine themselves called upon to help in a Manhattan Project, or see themselves sleuthing about in a forensic science like cosmology. In this talk I share sample student responses to our class discussions on nuclear weapons, and on cosmology. The history of physics is too engaging to be appreciated only by physicists.

  9. "Everybody knows psychology is not a real science": Public perceptions of psychology and how we can improve our relationship with policymakers, the scientific community, and the general public.

    PubMed

    Ferguson, Christopher J

    2015-09-01

    In a recent seminal article, Lilienfeld (2012) argued that psychological science is experiencing a public perception problem that has been caused by both public misconceptions about psychology, as well as the psychological science community's failure to distinguish itself from pop psychology and questionable therapeutic practices. Lilienfeld's analysis is an important and cogent synopsis of external problems that have limited psychological science's penetration into public knowledge. The current article expands upon this by examining internal problems, or problems within psychological science that have potentially limited its impact with policymakers, other scientists, and the public. These problems range from the replication crisis and defensive reactions to it, overuse of politicized policy statements by professional advocacy groups such as the American Psychological Association (APA), and continued overreliance on mechanistic models of human behavior. It is concluded that considerable problems arise from psychological science's tendency to overcommunicate mechanistic concepts based on weak and often unreplicated (or unreplicable) data that do not resonate with the everyday experiences of the general public or the rigor of other scholarly fields. It is argued that a way forward can be seen by, on one hand, improving the rigor and transparency of psychological science, and making theoretical innovations that better acknowledge the complexities of the human experience.

  10. Exploring the beliefs of persisting secondary science teachers in general induction programs: A longitudinal study

    NASA Astrophysics Data System (ADS)

    Wong, Sissy Sze-Mun

    Experienced, prepared, and fully certified teachers have been related with higher student achievement, but teacher retention has been a challenge for many decades, especially retention of secondary science teachers. In order to support teachers and student learning, it is critical to understand what impacts secondary science teachers' decisions to persist in the field. This mixed methods study explored whether teacher beliefs were related to persistence over a three-year period. Participants were beginning secondary science teachers that participated in general induction programs provided by their school or district. These participants were selected due to their representative nature of the average beginning secondary science teacher in the United States. Participants' responses to annual semi-structured interviews were the source of data. Findings from quantitative and qualitative analyses revealed that the persisting teachers' beliefs remained stable over the three-year period. Quantitative analyses also revealed that there were no prevalent beliefs among the persisting teachers, even when the variables of gender and socioeconomic status of their schools were considered. When persisting teachers' beliefs about teaching and beliefs about learning were quantitatively analyzed, no relationship was found. Case study of one persisting teacher and one non-persisting teacher revealed that personal experiences and knowledge impacted their beliefs about teaching and learning. The persisting teacher that participated in inquiry-based experiences held student-centered beliefs, while the non-persisting teacher that participated in verification-type experiences held teacher-centered beliefs. This study contributes to the field of science education by examining science teacher persistence instead of attrition. It focused specifically on secondary science teachers while exploring their beliefs longitudinally. Implications from this study calls for teacher beliefs to be

    This paper presents the first months of operation of the scientists-initiated Climanosco.org platform. The goal of this initiative is to bridge climate sciences with the general public by building a network of climate scientists and citizens around the world, by stimulating the writing of quality climate science articles in non-scientific language, and by publishing these articles in an open-access, multilingual format. For the climate scientist, this platform will offer a simple and reliable channel to disseminate research results to the general public. High standards are enforced by: a) requiring that the main author is an active climate scientist, and b) an innovative peer-review process involving scientific and non-scientific referees with distinct roles. Direct participation of non-scientists is allowed through co-authoring, peer-reviewing, language translation. Furthermore, public engagement is stimulated by allowing non-scientists to invite manuscripts to be written by scientists on topics of their concern. The targeted public includes journalists, teachers, students, local politicians, economists, members of the agriculture sector, and any other citizens from around the world with an interest in climate sciences. The initiative is now several months into operations. In this paper, I will discuss what we have achieved so far and what we plan for the next future.

  14. Measuring victimization inside prisons: questioning the questions.

    Wolff, Nancy; Jing Shi; Bachman, Ronet

    2008-10-01

    Violence and victimization inside the prison setting are accepted as facts, although the facts about their prevalence remain uncertain. Variation in the methods used to estimate rates of sexual and physical victimization contribute to the wide range in estimates appearing in the prison literature. This article focuses on the questions used in the prison victimization literature to elicit information on victimization from inmates, compared to questions used in the general victimization literature. The questions used in the National Violence Against Women and Men Surveys are used to estimate sexual and physical victimization rates for an entire prison system. Rates of victimization were found to vary significantly by specificity of the question, definition of perpetrator, and clustering of behaviors. Facts about victimization inside prison will become more certain when the methodology becomes more standardized and consistent with definitions of victimization. PMID:18309042

  15. Making Connections to Students' Lives and Careers Throughout a General Education Science Course

    2014-12-01

    The University of Oklahoma's general education lecture course Severe & Unusual Weather, taught in two sections each fall and spring, covers about nine topics. The sections are taught by different instructors, each of whom has flexibility to employ a variety of instructional strategies and choose specific topics to cover while meeting the requirement that general education courses in the natural sciences help students understand the importance of the science for appreciating the world around them. Students enrolled have been approximately 6-10% returning adult students, some of whom were veterans or active duty military, and about 10% members of racial or ethnic groups. Their majors are mostly in the humanities (theater, photography) and social sciences (education, English, journalism, sociology), with some natural science majors (psychology, aviation). For the past two years, Section 001 has been designed with adult and active learning concepts in mind, using deliberate connections between course content and students' lives and careers to motivate meaningful learning. Students were grouped in teams according to similar majors and assigned group presentations connecting course content to topics that should interest them, such as economic impacts of weather, societal and personal impacts of severe weather, risks to aviation, media coverage of weather, and psychological and sociological responses to weather risks. Students learn about the peer review process for scientific papers while also exploring a connection of course content to their future career or life interests through papers that are run through a mock peer review process. Public policy is discussed in several sections of the course, such as hurricane building codes, wind-resistant construction in tornado alley, and the disproportionate impacts of weather and climate on certain socioeconomic groups. Most students deeply appreciate the opportunity to explore how course content intersects with their lives

  17. Investigating the effectiveness of implementing the Science Writing Heuristic on student performance in general chemistry

    NASA Astrophysics Data System (ADS)

    Poock, Jason Ray

    This research investigated the effectiveness at how the Science Writing Heuristic in the freshman chemistry laboratory for science and engineering majors at Iowa State University during the fall and spring semesters of the 2002--2003 academic year, was implemented. The Science Writing Heuristic (SWH) consists of two components, writing to learn strategies and conducting the laboratory session in a student-centered, guided-inquiry fashion. The writing component replaced the standard laboratory report with a series of questions that guided the students' critical thinking along the lines of scientific investigation. The writing process helped students construct knowledge. Also critical to the successful implementation of the SWH was conducting the laboratory experiments in a student-centered, guided-inquiry fashion. Through the SWH the students became engaged in meaningful scientific dialogue that promoted knowledge construction. For the SWH to be properly implemented, a classroom dynamic between the teacher and the students should be established. The teacher provides the framework within which the laboratory experiment is conducted and the students respond to that guidance by becoming engaged in the learning process. Results of the study showed that student scores improved when the teacher properly implemented the SWH, when the students responded positively to the implementation of the SWH, and when there was a proper classroom dynamic created between the teacher and the students. This study revealed that successful implementation of the SWH was beneficial to females and low ability students. This research also demonstrated a connection between the implementation of a learning strategy in the laboratory component of a course and the subsequent benefit in student performance in the lecture component of the course.

  19. Teaching and learning the geological knowledge as a part of the science education general field

    NASA Astrophysics Data System (ADS)

    Aguirre-Pérez, Constancio

    2010-05-01

    Since the early 50s of last century the Teaching of Science has undergone a process of continuous development, (Gutiérrez, 1987; Aliberas, Gutierrez and Izquierdo, 1989) to become a scientific discipline largely accepted as such by many different universities worldwide. Besides, the proliferation of publications, magazines, conferences, symposia, meetings, and so on, proves this assertion. In these publications and meetings the Teaching of Science (or Science Education in more general terms) is addressed as a new field of research, teaching and educational innovation focused on the processes of teaching and learning of the experimental sciences (all of them: Physics, Chemistry, Biology and Geology). The study of this discipline is undertaken from different pedagogical, epistemological, psychological and sociological approaches. From this general perspective we can say that over the last two decades each of the sciences has developed specific characteristics so that, today, we could speak about specific didactics for each one of them. In the case of Geology (or Geoscience) Teaching there have been significant contributions from the following fields of research: the students' prior ideas (constructivist approach), the history of geology (as a subject-specific field) and from epistemology (Pedrinaci, E. 2000). The body of geoscience knowledge has an internal logic (as happens with the other science subjects) that allows us to organize the contents to teach, selecting, arranging and establishing proper relations between them. Still geology has a central, transverse, inter-and transdisciplinary character for its relationship with the other sciences. This character makes it appear as one of the disciplines with a huge potential to combine different methodologies of teaching and learning and different learning models already tested in the research field of Physics, Chemistry or Biology Education. Moreover, the most recent term coined for it "geosciences or earth and

  1. Recommendations for describing statistical studies and results in general readership science and engineering journals.

    PubMed

    Gardenier, John S

    2012-12-01

    This paper recommends how authors of statistical studies can communicate to general audiences fully, clearly, and comfortably. The studies may use statistical methods to explore issues in science, engineering, and society or they may address issues in statistics specifically. In either case, readers without explicit statistical training should have no problem understanding the issues, the methods, or the results at a non-technical level. The arguments for those results should be clear, logical, and persuasive. This paper also provides advice for editors of general journals on selecting high quality statistical articles without the need for exceptional work or expense. Finally, readers are also advised to watch out for some common errors or misuses of statistics that can be detected without a technical statistical background. PMID:21327724

    2015-10-01

    In Turkey and many other countries, the importance of the interactive whiteboard (IWB) is increasing, and as a result, projects and studies are being conducted regarding the use of the IWB in classrooms. Accordingly, in these countries, many issues are being researched, such as the IWB's contribution to the education process, its use in classroom settings and problems that occur when using the IWB. In this context, the research and analysis of studies regarding the use of the IWB have important implications for educators, researchers and teachers. This study aims to review and analyze studies conducted regarding the use of the IWB in the field of science. Accordingly, as a thematic review of the research was deemed appropriate, extant articles available in the literature were analyzed using a matrix that consisted of general features (type of journal, year and demographic properties) and content features (rationales, aims, research methods, samples, data collections, results and suggestions). According to the findings, it was concluded that the studies regarding the use of IWBs were conducted due to deficiencies in the current literature. However, there are rare studies in which the reasons for the research were associated with the nature of science education. There were also studies that focused on the effects of the IWB on student academic success and learning outcomes. Within this context, it is evident that there is a need for further research concerning the use of IWBs in science education and for studies regarding the effect of IWBs on students' skills.

    Replication is an essential requirement for scientific discovery. The current study aims to generalize and replicate 10 propositions made in previous Twitter studies using a representative dataset. Our findings suggest 6 out of 10 propositions could not be replicated due to the variations of data collection, analytic strategies employed, and inconsistent measurements. The study's contributions are twofold: First, it systematically summarized and assessed some important claims in the field, which can inform future studies. Second, it proposed a feasible approach to generating a random sample of Twitter users and its associated ego networks, which might serve as a solution for answering social-scientific questions at the individual level without accessing the complete data archive.

  13. What is a Question?

    NASA Astrophysics Data System (ADS)

    Knuth, Kevin H.

    2003-03-01

    A given question can be defined in terms of the set of statements or assertions that answer it. Application of logical inference to these sets of assertions allows one to derive the logic of inquiry among questions. There are interesting symmetries between the logics of inference and inquiry; where probability describes the degree to which a premise implies an assertion, there exists an analogous measure that describes the bearing or relevance that a question has on an outstanding issue. These have been extended to suggest that the logic of inquiry results in functional relationships analogous to, although more general than, those found in information theory. Employing lattice theory, I examine in greater detail the structure of the space of assertions and questions demonstrating that the symmetries between the logical relations in each of the spaces derive directly from the lattice structure. Furthermore, I show that while symmetries between the spaces exist, the two lattices are not isomorphic. The lattice of assertions is described by a Boolean lattice 2N, whereas the lattice of assuredly real questions is shown to be a sublattice of the free distributive lattice FD(N) = 22N. Thus there does not exist a one-to-one mapping of assertions to questions, there is no reflection symmetry between the two spaces, and questions in general do not possess complements. Last, with these lattice structures in mind, I discuss the relationship between probability, relevance, and entropy.

  15. A Citizen Empowered Online Platform for Communicating Climate Science to the General Public

    NASA Astrophysics Data System (ADS)

    Bourqui, Michel

    2014-05-01

    This presentation introduces a project, currently in development, of a new online platform for the interaction between climate scientists and citizen. It consists of an open-access, multi-lingual, and peer-reviewed journal publishing climate articles in non-scientific language. It follows three main long-term objectives. The first objective is to establish an ever-growing, multi-lingual library of climate articles providing a knowledge base on climate sciences accessible for free to everyone. The targeted public includes journalists, teachers, students, local actors (e.g. in politics, economy, agriculture), and any other citizen from around the world with an interest in climate sciences. The second goal is to offer a simple and direct channel for scientists wishing to disseminate their research to the general public. A high standard of climate articles is enforced through: a) requiring that the main author is an active climate scientist, and b) an innovative peer-review process involving scientific and non-scientific referees with distinct roles. The third objective is to engage citizen into the climate science. To this aim, the journal proposes three channels. Firstly, citizens are invited to contribute to the dissemination of climate knowledge to the general public by co-authoring, peer-reviewing or translating articles. Secondly, they are offered the capacity to stimulate scientific enquiry by posting invitations for manuscripts to be written on a citizen-inspired topic. Thirdly, a match-up tool is being developed for scientists to gather non-scientists teams for conducting citizen-involving research projects. This platform is scientist-initiated and is meant to be ruled and managed by the participating individuals themselves (scientists and non-scientists) as an international association. It will be financed through country-varying flat memberships. The project is now starting. The basic ideas are drawn; a prototype internet platform has been developed and is

    2016-06-01

    Recently, the inverted instruction methodologies are gaining attentions in higher educations by claiming that flipping the classroom engages more effectively students with the learning process. Besides, students' perceptions and emotions involved in their learning process must be assessed in order to gauge the usability of this relatively new instruction methodology, since it is vital in the educational formation. For this reason, this study intends to evaluate the students' perceptions and emotions when a flipped classroom setting is used as instruction methodology. This research was conducted in a general science course, sophomore of the Primary Education bachelor degree in the Training Teaching School of the University of Extremadura (Spain). The results show that the students have the overall positive perceptions to a flipped classroom setting. Particularly, over 80 % of them considered that the course was a valuable learning experience. They also found this course more interactive and were willing to have more courses following a flipped model. According to the students' emotions toward a flipped classroom course, the highest scores were given to the positive emotions, being fun and enthusiasm along with keyword frequency test. Then, the lowest scores were corresponded to negative emotions, being boredom and fear. Therefore, the students attending to a flipped course demonstrated to have more positive and less negative emotions. The results obtained in this study allow drawing a promising tendency about the students' perceptions and emotions toward the flipped classroom methodology and will contribute to fully frame this relatively new instruction methodology.

    Spatio-temporal statistical models are increasingly being used across a wide variety of scientific disciplines to describe and predict spatially-explicit processes that evolve over time. Correspondingly, in recent years there has been a significant amount of research on new statistical methodology for such models. Although descriptive models that approach the problem from the second-order (covariance) perspective are important, and innovative work is being done in this regard, many real-world processes are dynamic, and it can be more efficient in some cases to characterize the associated spatio-temporal dependence by the use of dynamical models. The chief challenge with the specification of such dynamical models has been related to the curse of dimensionality. Even in fairly simple linear, first-order Markovian, Gaussian error settings, statistical models are often over parameterized. Hierarchical models have proven invaluable in their ability to deal to some extent with this issue by allowing dependency among groups of parameters. In addition, this framework has allowed for the specification of science based parameterizations (and associated prior distributions) in which classes of deterministic dynamical models (e. g., partial differential equations (PDEs), integro-difference equations (IDEs), matrix models, and agent-based models) are used to guide specific parameterizations. Most of the focus for the application of such models in statistics has been in the linear case. The problems mentioned above with linear dynamic models are compounded in the case of nonlinear models. In this sense, the need for coherent and sensible model parameterizations is not only helpful, it is essential. Here, we present an overview of a framework for incorporating scientific information to motivate dynamical spatio-temporal models. First, we illustrate the methodology with the linear case. We then develop a general nonlinear spatio-temporal framework that we call general quadratic

    2006-12-01

    Software supporting an online conference series was developed with the purpose of catalyzing interdisciplinary investigations in Sun-Earth system science among large groups of researchers worldwide in celebration of the 50th anniversary of the International Geophysical Year in 2007. Transformative science in this area lies at the edges and intersections of individual elements (the Sun, heliosphere, magnetosphere, ionosphere and atmosphere) whose collective behavior determines the global system response. Continuing progress requires access to a vast developing cyber-infrastructure of large international data sets, high performance computing and advanced visualization. However, it also requires the development of new tools that bring these advances into contact with groups of interdisciplinary and international researchers so they can be used to attack grand challenge science issues in a manner not previously possible. This presentation describes the results of an eGY showcase project to develop a testbed online conference series for this purpose. The conference series is a collaborative effort between the CAWSES, IHY, eGY, ICESTAR, NASA/LWS and NSF Atmospheric Sciences Programs. Lessons learned in developing this first interface, as well as a discussion of key elements and how they worked will be presented.

  13. Major Challenges for the Modern Chemistry in Particular and Science in General

    PubMed Central

    Uskokovíc, Vuk

    2013-01-01

    In the past few hundred years, science has exerted an enormous influence on the way the world appears to human observers. Despite phenomenal accomplishments of science, science nowadays faces numerous challenges that threaten its continued success. As scientific inventions become embedded within human societies, the challenges are further multiplied. In this critical review, some of the critical challenges for the field of modern chemistry are discussed, including: (a) interlinking theoretical knowledge and experimental approaches; (b) implementing the principles of sustainability at the roots of the chemical design; (c) defining science from a philosophical perspective that acknowledges both pragmatic and realistic aspects thereof; (d) instigating interdisciplinary research; (e) learning to recognize and appreciate the aesthetic aspects of scientific knowledge and methodology, and promote truly inspiring education in chemistry. In the conclusion, I recapitulate that the evolution of human knowledge inherently depends upon our ability to adopt creative problem-solving attitudes, and that challenges will always be present within the scope of scientific interests.

  20. The effects of question types in textual reading upon retention of biology concepts

    NASA Astrophysics Data System (ADS)

    Leonard, William H.; Lowery, Lawrence F.

    Do instructional questions to students enhance learning? If so, do certain types of questions cause greater learning outcomes than others? The area of instructional questions and questioning strategies has generated much research over the past two decades. A number of studies have found instructional questions to account for a large fraction of teaching time (Bellack et al., 1963; Schreiber, 1967; Moyer, 1967). Teacher use of oral questions in instruction, especially higher level cognitive questions, has consistently shown positive effects on student achievement (Redfield & Rousseau, 1981). Questions asked after oral prose presentations in psychology have been found to enhance recall of factual information (Sefkow & Meyers, 1980). Some large teacher training programs have specific instruction in questioning strategies (Lanier & Davis, 1972; Lowery, 1974). Questioning in textual reading has also been investigated, especially in the social sciences and languages, with respect to both the presence of questions in a text and the position and type of such questions. Although there are conflicting results, in general, questions placed within text materials have appeared to cause significantly higher performance than reading the materials without questions (Rothkopf & Bisbicos, 1967; Rothkopf & Bloom, 1970; Watts & Anderson, 1971; Quellmalz, 1972; Reynolds, Standiford, & Anderson, 1979; Corrozi, 1971). Questions placed after the reading have been found to be significantly more productive than prequestions, or questions placed immediately before the reading passages (Rothkopf & Bisbicos, 1967; Frase, Patrick, & Schumer, 1970; Watts & Anderson, 1971). In one study, placing questions before the associated information reduced paragraph reading time from the time required when questions followed the information passage (Morasky & Wilcox, 1970). Finally, higher level cognitive post- and prequestions (comprehensive and application) have consistently produced more learning than

    Writing, like science, is primarily a matter of noticing what goes on in the world and communicating these insights to others. Both require a certain amount of translation, and in the process, distortion. Writing about science is thus doubly cursed, and makes some surprising demands on the writer. Among the (only partly tongue-in-cheek) requirements to be discussed are: Lie; cheat; steal; dare to be stupid; don't trust your sources (or your editors); waste people's time; quote out of context; make arbitrary calls; don't expect anyone to understand you; don't expect anyone to believe you; prepare to make mistakes; avoid 'hardening of the categories'; debase yourself, but never your readers; eschew objectivity; emote.

    The findings of climate science need to be communicated to the general public. Researchers are encouraged to do so by journalists, policy-makers and funding agencies and many of us want to become better science communicators. But how can we do this at the lab or small research group level without specifically allocated resources in terms of funds and communication officers? And how do we sustain communication on a regular basis and not just during the limited lifetime of a specific project? One of the solutions is to use the emerging platform of social media, which has become a powerful and inexpensive tool for communicating science to different target audiences. Many research institutions and individual researchers are already advanced users of social media, but small research groups and labs remain underrepresented. The group of oceanographers, sea ice and atmospheric scientists at the Norwegian Polar Institute (@OceanSeaIceNPI( will share our experiences developing and maintaining researcher-driven outreach for over a year through Instagram, Twitter and Facebook. We will present our solutions to some of the practical considerations such as identifying key target groups, defining the framework for sharing responsibilities and interactions within the research group, and choosing an up-to-date and appropriate social medium. By sharing this information, we aim to inspire and assist other research groups and labs in conducting their own effective science communication.

  5. General Education Earth, Astronomy and Space Science College Courses Serve as a Vehicle for Improving Science Literacy in the United States.

    NASA Astrophysics Data System (ADS)

    Prather, E.

    2011-10-01

    Every year approximately 500,000 undergraduate college students take a general education Earth, Astronomy and Space Science (EASS) course in the Unites States. For the majority of these students this will be their last physical science course in life. This population of students is incredibly important to the science literacy of the United States citizenry and to the success of the STEM career pipeline. These students represent future scientists, technologists, business leaders, politicians, journalists, historians, artists, and most importantly, policy makers, parents, voters, and teachers. A significant portion of these students are taught at minority serving institutions and community colleges and often are from underserved and underrepresented groups, such as women and minorities. Members of the Center for Astronomy Education (CAE) at the University of Arizona have been developing and conducting research on the effectiveness of instructional strategies and materials that are explicitly designed to challenge students' naïve ideas and intellectually engage their thinking at a deep level in the traditional lecture classroom. The results of this work show that dramatic improvement in student understanding can be made from increased use of interactive learning strategies. These improvements are shown to be independent of institution type or class size, but appear to be strongly influenced by the quality of the instructor's implementation. In addition, we find that the positive effects of interactive learning strategies apply equally to men and women, across ethnicities, for students with all levels of prior mathematical preparation and physical science course experience, independent of GPA, and regardless of primary language. These results powerfully illustrate that all students can benefit from the effective implementation of interactive learning strategies.

    NASA Astrophysics Data System (ADS)

    Dodd, Matthew Robert

    General education and Special Education students from three high schools in Rutherford County were sampled to determine the effect on their academic achievement on the Tennessee Biology I Gateway Exam in Inclusion classrooms. Each student's predicted and actual Gateway Exam scores from the academic year 2006--2007 were used to determine the effect the student's classroom had on his academic achievement. Independent variables used in the study were gender, ethnicity, socioeconomic level, grade point average, type of classroom (general or Inclusion), and type student (General Education or Special Education). The statistical tests used in this study were a t-test and a Mann--Whitney U Test. From this study, the effect of the Inclusion classroom on general education students was not significant statistically. Although the Inclusion classroom allows the special education student to succeed in the classroom, the effect on general education students is negligible. This study also provided statistical data that the Inclusion classroom did not improve the special education students' academic performances on the Gateway Exam. Students in a general education classroom with a GPA above 3.000 and those from a household without a low socioeconomic status performed at a statistically different level in this study.

  8. Biology Question Generation from a Semantic Network

    NASA Astrophysics Data System (ADS)

    Zhang, Lishan

    Science instructors need questions for use in exams, homework assignments, class discussions, reviews, and other instructional activities. Textbooks never have enough questions, so instructors must find them from other sources or generate their own questions. In order to supply instructors with biology questions, a semantic network approach was developed for generating open response biology questions. The generated questions were compared to professional authorized questions. To boost students' learning experience, adaptive selection was built on the generated questions. Bayesian Knowledge Tracing was used as embedded assessment of the student's current competence so that a suitable question could be selected based on the student's previous performance. A between-subjects experiment with 42 participants was performed, where half of the participants studied with adaptive selected questions and the rest studied with mal-adaptive order of questions. Both groups significantly improved their test scores, and the participants in adaptive group registered larger learning gains than participants in the control group. To explore the possibility of generating rich instructional feedback for machine-generated questions, a question-paragraph mapping task was identified. Given a set of questions and a list of paragraphs for a textbook, the goal of the task was to map the related paragraphs to each question. An algorithm was developed whose performance was comparable to human annotators. A multiple-choice question with high quality distractors (incorrect answers) can be pedagogically valuable as well as being much easier to grade than open-response questions. Thus, an algorithm was developed to generate good distractors for multiple-choice questions. The machine-generated multiple-choice questions were compared to human-generated questions in terms of three measures: question difficulty, question discrimination and distractor usefulness. By recruiting 200 participants from

    The spacing effect describes the robust finding that long-term learning is promoted when learning events are spaced out in time, rather than presented in immediate succession. Studies of the spacing effect have focused on memory processes rather than for other types of learning, such as the acquisition and generalization of new concepts. In this study, early elementary school children (5–7 year-olds; N = 36) were presented with science lessons on one of three schedules: massed, clumped, and spaced. The results revealed that spacing lessons out in time resulted in higher generalization performance for both simple and complex concepts. Spaced learning schedules promote several types of learning, strengthening the implications of the spacing effect for educational practices and curriculum. PMID:22616822

    Citizen science has the potential to expand the scope and scale of research in ecology and conservation, but many professional researchers remain skeptical of data produced by nonexperts. We devised an approach for producing accurate, reliable data from untrained, nonexpert volunteers. On the citizen science website www.snapshotserengeti.org, more than 28,000 volunteers classified 1.51 million images taken in a large-scale camera-trap survey in Serengeti National Park, Tanzania. Each image was circulated to, on average, 27 volunteers, and their classifications were aggregated using a simple plurality algorithm. We validated the aggregated answers against a data set of 3829 images verified by experts and calculated 3 certainty metrics-level of agreement among classifications (evenness), fraction of classifications supporting the aggregated answer (fraction support), and fraction of classifiers who reported "nothing here" for an image that was ultimately classified as containing an animal (fraction blank)-to measure confidence that an aggregated answer was correct. Overall, aggregated volunteer answers agreed with the expert-verified data on 98% of images, but accuracy differed by species commonness such that rare species had higher rates of false positives and false negatives. Easily calculated analysis of variance and post-hoc Tukey tests indicated that the certainty metrics were significant indicators of whether each image was correctly classified or classifiable. Thus, the certainty metrics can be used to identify images for expert review. Bootstrapping analyses further indicated that 90% of images were correctly classified with just 5 volunteers per image. Species classifications based on the plurality vote of multiple citizen scientists can provide a reliable foundation for large-scale monitoring of African wildlife. PMID:27111678

    HgCdTe (MCT) is a very versatile material system for infrared (IR) detection, suitable for high performance detection in a wide range of applications and spectral ranges. Indeed, the ability to tailor the cutoff frequency as close as possible to the needs makes it a perfect candidate for high performance detection. Moreover, the high quality material available today, grown either by molecular beam epitaxy or liquid phase epitaxy, allows for very low dark currents at low temperatures, suitable for low flux detection applications such as science imaging. MCT has also demonstrated robustness to the aggressive environment of space and faces, therefore, a large demand for space applications. A satellite may stare at the earth, in which case detection usually involves a lot of photons, called a high flux scenario. Alternatively, a satellite may stare at outer space for science purposes, in which case the detected photon number is very low, leading to low flux scenarios. This latter case induces very strong constraints onto the detector: low dark current, low noise, (very) large focal plane arrays. The classical structure used to fulfill those requirements are usually p/n MCT photodiodes. This type of structure has been deeply investigated in our laboratory for different spectral bands, in collaboration with the CEA Astrophysics lab. However, another alternative may also be investigated with low excess noise: MCT n/p avalanche photodiodes (APD). This paper reviews the latest achievements obtained on this matter at DEFIR (LETI and Sofradir common laboratory) from the short wave infrared (SWIR) band detection for classical astronomical needs, to long wave infrared (LWIR) band for exoplanet transit spectroscopy, up to very long wave infrared (VLWIR) bands. The different available diode architectures (n/p VHg or p/n, or even APDs) are reviewed, including different available ROIC architectures for low flux detection.

    This talk introduces a scientists-initiated, new online platform whose aim is to contribute to making climate sciences become public knowledge. It takes a unique bottom-up approach, strictly founded on individual-based participation, high scientific standards and independence The main purpose is to build an open-access, multilingual and peer-reviewed journal publishing short climate articles in non-scientific language. The targeted public includes journalists, teachers, students, local politicians, economists, members of the agriculture sector, and any other citizens from around the world with an interest in climate sciences. This journal is meant to offer a simple and direct channel for scientists wishing to disseminate their research to the general public. A high standard of climate articles is ensured through: a) requiring that the main author is an active climate scientist, and b) an innovative peer-review process involving scientific and non-scientific referees with distinct roles. The platform fosters the direct participation of non-scientists through co-authoring, peer-reviewing, language translation. It furthermore engages the general public in the scientific inquiry by allowing non-scientists to invite manuscripts to be written on topics of their concern. The platform is currently being developed by a community of scientists and non-scientists. In this talk, I will present the basic ideas behind this new online platform, its current state and the plans for the next future. The beta version of the platform is available at: http://www.climateonline.bourquiconsulting.ch

    Despite the vast array of theoretical formulations now available, none is sufficiently well developed. Some of the philosophical questions thrown up by such material are posed. Under the heading of "Discourse," the questions of what constitutes reasonableness and how logical validity is established are raised. Under the heading of "Epistemology," the nature of concept formulation and causality is raised. Under the heading of "Language," the nature of linguistic representation and artificially constructed language or "artificial intelligence" is raised. It is suggested that these and other issues in the philosophy of science require the urgent attention of family therapy theorists. PMID:3754225

    This report documents the initial phases of the Materials Information for Science and Technology (MIST) project jointly supported by the Department of Energy and the National Bureau of Standards. The purpose of MIST is to demonstrate the power and utility of computer access to materials property data. The initial goals include: to exercise the concept of a computer network of materials databases and to build a demonstration of such a system suitable for use as the core of operational systems in the future. Phases I and II are described in detail herein. In addition, a discussion is given of the expected usage of the system. The primary MIST prototype project is running on an IBM 3084 under STS at the Stanford University's Information Technology Services (ITS). Users can access the Stanford system via ARPANET, TELENET, and TYMNET, as well as via commercial telephone lines. For fastest response time and use of the full screen PRISM interface, direct connection using a 2400 baud modem with the MNP error-correcting protocol over standard telephone lines gives the best results - though slower speed connections and a line-oriented interface are also available. This report gives detailed plans regarding the properties to be enterend and the materials to be entered into the system.

    Currie, D.; Thompson, D.; Buck, S.; Des Georges, R.; Ho, C.; Remelius, D.; Shirey, B.; Gabriele, T.; Gamiz, V.; Ulibarri, L.; Hallada, M.; Szymanski, P.

    RULLI (Remote Ultra-Low Light Imager) is a unique single photon imager with very high (microsecond) time resolution and continuous sensitivity, developed at Los Alamos National Laboratory. This technology allows a family of astrophysical and satellite observations that were not feasible in the past. We will describe the results of the analysis of recent observations of the LAGEOS II satellite and the opportunities expected for future observations of the Crab nebula. The LAGEOS/LARES experiments have measured the dynamical General Relativistic effects of the rotation of the earth, the Lense-Thirring effect. The major error source is photon thrust and a required knowledge of the orientation of the spin axis of LAGEOS. This information is required for the analysis of the observations to date, and for future observations to obtain more accurate measurements of the Lense-Thirring effect, of deviations from the inverse square law, and of other General Relativistic effects. The rotation of LAGEOS I is already too slow for traditional measurement methods and Lageos II will soon suffer a similar fate. The RULLI camera can provide new information and an extension of the lifetime for these measurements. We will discuss the 2004 LANL observations of LAGEOS at Starfire Optical Range, the unique software processing methods that allow the high accuracy analysis of the data (the FROID algorithm) and the transformation that allows the use of such data to obtain the orientation of the spin axis of the satellite. We are also planning future observations, including of the nebula surrounding the Crab Pulsar. The rapidly rotating pulsar generates enormous magnetic fields, a synchrotron plasma and stellar winds moving at nearly the velocity of light. Since the useful observations to date rely only on observations of the beamed emission when it points toward the earth, most descriptions of the details of the processes have been largely theoretical. The RULLI camera's continuous

  11. Literacy, science, and science education

    NASA Astrophysics Data System (ADS)

    McVittie, Janet Elizabeth

    In examining the connections between literacy, science and science education, I laid out a number of questions. For example, what sorts of literate tools might facilitate writing to learn, and do children who are just becoming literate use these tools? I then examined the writing of children in science class in an attempt to determine if their writing can indeed facilitate their learning. The results of this research could help teachers make decisions about the use of writing in the learning of science. The kinds of literate tools I identified as being potentially helpful were transitionals---those words or grammatical devices which demonstrate how ideas are connected. Also, I suggested that data tables, sentences and paragraphs were also useful for students to learn. I found that grade 5/6 students used a wide range of literate tools, but that they were much more competent with those tools which were both oral and literate than those which could only be used for writing (punctuation, sentences, paragraphs, and data tables). When I attempted to determine if the children used their writing to learn, I found very little evidence that this was certainly so. However, there was some evidence that paragraphs had the potential to create a "dialogue" between student writing and thinking, so the students could make more explicit connections between science ideas. Lastly, I noticed certain gender difference in the classroom. Because of this, I contrasted the writing of the girls with the writing of the boys. I learned the girls were generally much more capable writers than the boys. More interesting, however, was that the girls generally attempted to explain their science concepts in different ways than did the boys. The girls were more likely to rely on their own reasoning, whereas the boys were more likely to persist in using culturally created science explanations. The research findings have important implications for analyzing students' learning and for finding ways to

    Progress monitoring is a type of formative assessment. Most work on progress monitoring in elementary school settings has been focused on students. However, teachers also can benefit from frequent evaluations. Research addressing teacher progress monitoring is critically important given the recent national focus on teacher evaluation and effectiveness. This special topic section of School Psychology Quarterly is the first to showcase the current research on measuring Tier 1 instructional and behavioral management practices used by prekindergarten and elementary school teachers in general education settings. The three studies included in the special section describe the development and validation efforts of several teacher observational and self-report measures of instruction and/or behavioral management. These studies provide evidence for the utility of such assessments for documenting the use of classroom practices, and these assessment results may be leveraged in innovative coaching models to promote best practice. These articles also offer insight and ideas for the next generation of teacher practice assessment for the field. Finally, the special topic is capped by a commentary synthesizing the current work and offers "big ideas" for future measurement development, policy, and professional development initiatives.

  14. Elementary General Education Teachers' Knowledge of and Experience Teaching Students with Disabilities in Science and Social Studies

    NASA Astrophysics Data System (ADS)

    Rice, Diane

    In Grades 3 to 5 at a suburban southeastern elementary school, the percentage of students with disabilities (SWDs) who do not meet state standards in science and social studies is greater than that of their nondisabled peers. To address this disparity, district administrators required that proficiency ratings increase for SWDs without providing general education (GE) teachers with training. A qualitative bounded case study was used to understand how GE teachers constructed their knowledge of and met SWDs instructional needs and to understand GE teachers' needs as they worked toward meeting the district goals. Piaget's constructivist learning theory served as the conceptual framework for this study. A purposeful sample of 6 GE teachers, 2 each from Grades 3-5 whose classrooms included SWDs, volunteered to participate in open-ended interviews. Qualitative data were analyzed using provisional coding and pattern coding. A primary finding was that the participants identified teacher collaboration and professional development necessary to accommodate SWDs in the GE setting. This finding led to a recommendation that school leaders provide ongoing professional development for GE teachers as well as ongoing opportunities for collaboration between GE and special education teachers. These endeavors may contribute to positive social change by providing GE teachers instructional strategies and accommodations for meeting the learning needs of SWDs to increase the number and percentage of SWDs who meet the state standards and district goals in science and social studies.

  1. Assessing students' learning outcomes, self-efficacy and attitudes toward the integration of virtual science laboratory in general physics

    NASA Astrophysics Data System (ADS)

    Ghatty, Sundara L.

    Over the past decade, there has been a dramatic rise in online delivery of higher education in the United States. Recent developments in web technology and access to the internet have led to a vast increase in online courses. For people who work during the day and whose complicated lives prevent them from taking courses on campus, online courses are the only alternatives by which they may achieve their goals in education. The laboratory courses are the major requirements for college and university students who want to pursue degree and certification programs in science. It is noted that there is a lack of laboratory courses in online physics courses. The present study addressed the effectiveness of a virtual science laboratory in physics instruction in terms of learning outcomes, attitudes, and self-efficacy of students in a Historically Black University College. The study included fifty-eight students (36 male and 22 female) of different science majors who were enrolled in a general physics laboratory course. They were divided into virtual and traditional groups. Three experiments were selected from the syllabus. The traditional group performed one experiment in a traditional laboratory, while the virtual group performed the same experiment in a virtual laboratory. For the second experiment, the use of laboratories by both groups was exchanged. Learner's Assessment Test (LAT), Attitudes Toward Physics Laboratories (ATPL), and Self-Efficacy Survey (SES) instruments were used. Additionally, quantitative methods such as an independent t-test, a paired t-test, and correlation statistics were used to analyze the data. The results of the first experiment indicated the learning outcomes were higher in the Virtual Laboratory than in the traditional laboratory, whereas there was no significant difference in learning outcomes with either type of lab instruction. However, significant self-efficacy gains were observed. Students expressed positive attitudes in terms of liking

  6. Questions for Surveys

    PubMed Central

    Schaeffer, Nora Cate; Dykema, Jennifer

    2011-01-01

    We begin with a look back at the field to identify themes of recent research that we expect to continue to occupy researchers in the future. As part of this overview, we characterize the themes and topics examined in research about measurement and survey questions published in Public Opinion Quarterly in the past decade. We then characterize the field more broadly by highlighting topics that we expect to continue or to grow in importance, including the relationship between survey questions and the total survey error perspective, cognitive versus interactional approaches, interviewing practices, mode and technology, visual aspects of question design, and culture. Considering avenues for future research, we advocate for a decision-oriented framework for thinking about survey questions and their characteristics. The approach we propose distinguishes among various aspects of question characteristics, including question topic, question type and response dimension, conceptualization and operationalization of the target object, question structure, question form, response categories, question implementation, and question wording. Thinking about question characteristics more systematically would allow study designs to take into account relationships among these characteristics and identify gaps in current knowledge.

  11. Rules of the Game: Effects of a Game-based Metaphor on Instructional Activity Design and the Use of Student Mentors on Learning Outcomes in a Middle School General Science Class

    NASA Astrophysics Data System (ADS)

    Dowling, Angie

    This study investigated the effects of a game-like environment on instructional activity design and the use of student mentors on learning outcomes in a middle school general science class. The participants for this study were 165 students, ages 13-14 years old, who were enrolled in 8th grade at a mid-Atlantic middle school. Two research questions were used to conduct the research: 1. Can science content be designed and successfully delivered instructionally using a game-like learning environment? 2. Does the use of student mentors/assistants help direct and maintain the flow of the class away from the technological issues toward the necessary learning outcomes while also increasing the science content understanding acquired by the mentors while also increasing class and student engagement? For this study an introductory biology unit was designed using a game-like curricular structure. Student mentors were utilized in order to aid focus on the content and not the technology. The results indicated that the instructional design of the unit using a game-like environment was successful and students exhibited learning. The mentor students were instrumental in steering their fellow students away from the “Siren’s Call” of the instrument (in this case StarLogo) and enabled increased focus on the content. Keywords: Trivial games, Serious Games, Epistemic Games, Student Mentors, StarLogo, Elaboration Theory.

    Are you doing the job that our society needs you to do? Are you successful at it? How do you know? Over the past decade we have worked closely with hundreds of college instructors, postdocs, graduate students, and undergrads in collaborative research projects designed to help us understand fundamental issues of teaching and learning in college-level general education astronomy and space science courses. The results from these multi-institutional research collaborations have been used to transform classrooms all over the country. We are creating learning environments that significantly improve the science literacies and engagements in STEM of the hundreds of thousands of students taking these courses each year. By moving students along the continuum from non-science majors, to peer instructors, to researchers and curriculum developers, to STEM and STEM education degree seeking students, we are creating the next generation’s “Ambassadors of Science.”

    Nobel, Michele Mcmahon

    2005-07-01

    This study investigated the effects of classwide peer tutoring (CWPT) on the acquisition, maintenance, and generalization of science vocabulary words and definitions. Participants were 14 seventh grade students at-risk for failure in a general education science course; 3 students had learning disabilities and 2 had a communication disorder. CWPT was conducted daily for 20 minutes during the last period of the school day. Procedures for CWPT were consistent with the Ohio State University CWPT model. Students were engaged in dyadic, reciprocal tutoring. Tutors presented word cards to tutees to identify the word and definition. Tutors praised correct responses and used a correction procedure for incorrect responses. After practicing their vocabulary words, students completed a daily testing procedure and recorded and plotted data. Many of the study's findings are consistent with previous studies using CWPT to teach word identification. Results of this study indicate a functional relationship between CWPT and acquisition of science vocabulary. All students were able to acquire words and definitions. Results for maintenance and generalization varied. When acquisition criterion was changed, maintenance and generalization scores increased for some students, while other students remained consistently high. All students reported that they enjoyed CWPT, and all but student stated it helped them learn science vocabulary.

  6. Knowledge and question asking.

    PubMed

    Ibáñez Molinero, Rafael; García-Madruga, Juan Antonio

    2011-02-01

    The ability and the motivation for question asking are, or should be, some of the most important aims of education. Unfortunately, students neither ask many questions, nor good ones. The present paper is about the capacity of secondary school pupils for asking questions and how this activity depends on prior knowledge. To examine this, we use texts containing different levels of information about a specific topic: biodiversity. We found a positive relationship between the amount of information provided and the number of questions asked about the texts, supporting the idea that more knowledgeable people ask more questions. Some students were warned that there would be an exam after the reading, and this led to a diminishing number of questions asked, and yet this still did not significantly improve their exam scores. In such a case, it seems that reading was more concerned with immediacy, hindering critical thinking and the dialog between their previous ideas and the new information. Thus, question asking seems to be influenced not only by the amount of knowledge, but also by the reader's attitude towards the information. PMID:21266138

    NASA Astrophysics Data System (ADS)

    Kotas, Ronald

    2014-03-01

    The concept of General Relativity is not compatible with Quantum Mechanics. General Relativity is not real science, only a fallacy concept with no definitive proofs. It is not based on reality. Light and other radiation are not bent by General Relativity, only by Newtonian Refractions in the Sun's very hot Corona. The planet Mercury orbital perihelion is not a proof of General Relativity; it is fully and logically explained by Newtonian Mechanics. The dynamic 2/3rds ratio of Mercury's day-to-year ratio is profound and a Nuclear Quantum Gravitational function, not General Relativity. The Red Shift is a Nuclear Quantum Gravitational effect, not General Relativity. The so-called gravitational lens is also where refraction of gaseous matter, dust or real objects are not considered. No ``gravity waves'' have ever been detected by any LIGO site in the world. No material ``frame dragging'' has been detected by the Gravity B probe. The reason is that there is no space fabric to cause these effects. It should be perfectly clear that General Relativity has no definitive proofs and is not a real or correct description of Science. Nuclear Quantum Gravitation is a clear explanation of Gravity/Gravitation with 31 proofs and indications, and is compatible with Quantum and Newtonian Mechanics.

  15. [Questions by adolescents about dieting].

    PubMed

    Bloch, A

    1989-12-15

    In recent years there has been increasing concern and involvement of Israeli adolescents with dieting. An increase in the incidence of obesity has been emphasized by the mass media. This has been marked by an increase in the number of questions on dieting sent anonymously by 12 to 14 year-olds to a column in a popular youth magazine about adolescent sexuality. These letters include requests for diets to prevent obesity in general and fatness of certain parts of the body in particular, such as the thighs or buttocks; questions as to side-effects of diets already started, particularly amenorrhea; and questions about the onset of bulimia and anorexia nervosa, expressing fear of the consequences. This study gives examples of the questions and the answers, and indicates the professions of those to whom the applicants were referred for further diagnosis and treatment. Newer techniques of health education with regard to adolescent dieting are urgently needed so that the health staff can promote insight and indicate the need for treatment at as early a stage as possible. The use of mass media in a suitable manner is critical, given the increase in diet-advertising. PMID:2620891

    Astronomy is not only a branch of science but also an important part of the culture and civilisations of peoples. Starting with archeoastronomy to the present day, it has always contributed to a better understanding of life, of humanity. After 400 years of modern astronomy, it still addresses major problems such as: Why there is something rather than nothing? Why is nature comprehensible to humans? How is cosmos related to humanity? Do multiverses exist? Is there life on other planets? Are we alone in the universe? Does the universe have a beginning? If so, what does it mean? How did the universe originate? All these questions are a challenge for interdisciplinary and transdisciplinary investigations, for philosophers, physicists, cosmologists, mathematicians, theologians. The new insights gained by pursuing in depth these common investigations will shape the society we live in and have important consequences on the future we are creating.

    In general, it can be stated that unfortunately in most countries the number of students interested in traditional scientific disciplines (e.g. physics, chemistry, biology, mathematics, etc.) for his/her future professional careers has considerably decreased during the past years. It is likely that among the reasons of this trend we can find that many students feel that these disciplines are particularly difficult, complex, abstract, and even boring, while they consider applied sciences (e.g. engineering) as much more attractive options to them. Here we aim to attract people of very different ages to traditional scientific disciplines, and promote scientific knowledge, using a set of colour questions related to everyday experiences. From our answers to these questions we hope that people can understand and learn science in a rigorous, relaxed and amusing way, and hopefully they will be inspired to continue exploring on their own. Examples of such colour questions can be found at the free website http://whyiscolor.org from Mark D. Fairchild. For a wider dissemination, most contents of this website have been recently translated into Spanish language by the authors, and published in the book entitled "La tienda de las curiosidades sobre el color" (Editorial University of Granada, Spain, ISBN: 9788433853820). Colour is certainly multidisciplinary, and while it can be said that it is mainly a perception, optics is a key discipline to understand colour stimuli and phenomena. The classical first approach in colour science as the result of the interaction of light, objects, and the human visual system will be also reviewed.

    In this paper I expand on the premises of Jesse Bazzul's thesis in his paper, Neoliberal ideology, global capitalism, and science education: engaging the question of subjectivity, exploring the implications of the ideologies within the culturally emerging logic of science exposes the incommensurability of intents and purposes in its methods and epistemology. I argue that science needs to acknowledge the subjectivity at its core to make space for non-absolute agents and new fields of study.

    We live in a fast moving-world. Business has accelerated to breathtaking speeds in the 1990s--and in the last few years the afterburner has really kicked in. The speed of change is overwhelming. Especially in health care, who has time to "live in the question?" We need to decide things quickly, get the decision out of the way, and move on, right? Maybe. Biology shows us that you can't plan ahead very far. New things come along that you don't even have a category for, and therefore you don't even see them. Things are going to happen that you literally have no notion are even possible. The key to succeeding in this environment? Don't plan ahead. Stay curious. Make small bets. Build organizational hothouses. Feed the seedlings that grow. The challenge is to remain curious, to live in the question, both personally and organizationally. PMID:10557490

    The natural language database query system incorporated in the Knobs Interactive Planning System comprises a dictionary driven parser, APE-II, and script interpreter whch yield a conceptual dependency as a representation of the meaning of user input. A conceptualisation pattern matching production system then determines and executes a procedure for extracting the desired information from the database. In contrast to syntax driven q-a systems, e.g. those based on atn parsers, APE-II is driven bottom-up by expectations associated with word meanings. The goals of this approach include utilising similar representations for questions with similar meanings but widely varying surface structures, developing a powerful mechanism for the disambiguation of words with multiple meanings and the determination of pronoun referents, answering questions which require inferences to be understood, and interpreting ellipses and ungrammatical statements. The Knobs demonstration system is an experimental, expert system for air force mission planning applications. 16 refs.

  10. Neutrino Oscillations:. Hierarchy Question

    The only experimentally observed phenomenon that lies outside the standard model of the electroweak interaction is neutrino oscillations. A way to try to unify the extensive neutrino oscillation data is to add a phenomenological mass term to the Lagrangian that is not diagonal in the flavor basis. The goal is then to understand the world's data in terms of the parameters of the mixing matrix and the differences between the squares of the masses of the neutrinos. An outstanding question is what is the correct ordering of the masses, the hierarchy question. We point out a broken symmetry relevant to this question, the symmetry of the simultaneous interchange of hierarchy and the sign of θ13. We first present the results of an analysis of data that well determine the phenomenological parameters but are not sensitive to the hierarchy. We find θ13 = 0.152±0.014, θ 23 = 0.25{ - 0.05}{ + 0.03} π and Δ32 = 2.45±0.14×10-3 eV2, results consistent with others. We then include data that are sensitive to the hierarchy and the sign of θ13. We find, unlike others, four isolated minimum in the χ2-space as predicted by the symmetry. Now that Daya Bay and RENO have determined θ13 to be surprisingly large, the Super-K atmospheric data produce meaningful symmetry breaking such that the inverse hierarchy is preferred at the 97.2 % level.

    The first section of this memoir queries my formative years. Indirectly I address the question, did my childhood and early years make a difference in my choice of career? Why and how did I begin my journey to becoming a scientist? Did I choose the field of solar astronomy or did circumstances dictate it for me? In the second section, I travel through my work environments and experiences, talking about interactions and aspects of being a scientist that do not appear in our research papers. What parts of my research were happenstances and what parts did I plan? What does it feel like to be on scientific quests? Using examples in my journey, I also turn to questions that have intrigued me throughout my sojourn as a solar astronomer. How do scientific discoveries come about? What factors lead to little discoveries? And what factors lead to major exciting discoveries? Are there timely questions we do not think to ask? How can small, seemingly scattered pieces of knowledge suddenly coalesce into a deeper understanding - what is called the "Aha!" experience - the times when our mental light switches on, and with child-like wonder we behold a "big picture"?

    2014-01-01

    This study evaluated the prevalence of general and abdominal obesity among students of the University for Development Studies, School of Medicine and Health Sciences (UDS-SMHS), Tamale, Ghana. Also, lifestyle risk factors for the two obesity indices were investigated. This study was conducted among a sample of 646 students. Anthropometric measures of weight, height, and waist circumference were appropriately assessed. The prevalence of general and abdominal obesity was 1.9% and 4.2%, respectively. Risk factors of general obesity were being female (crude OR = 6.9, 95% CI = 1.85–25.80, P = 0.0021), engaging in light PA (OR = 12.45, 95% CI = 2.96–52.41, P = 0.0006), being aged 28–37 years (OR = 5.37, 95% CI = 1.39–20.68, P = 0.0329), nonintake of coffee (OR = 4.1, 95% CI = 1.10–15.28, P = 0.0357), being married (OR = 5.7, 95% CI = 1.48–22.02, P = 0.0286), and being abdominally obese (OR = 02.7, 95% CI = 25.61–11.60, P < 0.0001). Risk factors for abdominal obesity were being female, being married, having general obesity, and nonintake of coffee. Abdominal obesity was more prevalent than general obesity. Risk factors included being female, married, and generally obese and nonintake of coffee. PMID:24649393

    A career in science is shaped by many factors, one of the most important being our tastes in research. These typically form early and are shaped by subsequent successes and failures. My tastes run to microscopes, chemistry, and spatial organization of cytoplasm. I will try to identify where they came from, how they shaped my career, and how they continue to evolve. My hope is to inspire young scientists to identify and celebrate their own unique tastes. PMID:24174461

  17. Using a creativity-focused science program to foster general creativity in young children: A teacher action research study

    NASA Astrophysics Data System (ADS)

    Gomes, Joan Julieanne Mariani

    The importance of thinking and problem-solving skills, and the ability to integrate and analyze information has been recognized and yet may be lacking in schools. Creativity is inherently linked to problem finding, problem solving, and divergent thinking (Arieti, 1976; Csikszentmihalyi, 1990; Milgram, 1990). The importance of early childhood education and its role in the formation of young minds has been recognized (Caine & Caine, 1991; Montessori, 1967a, 1967b; Piaget, 1970). Early childhood education also impacts creativity (Gardner, 1999). The features of brain-based learning (Caine & Caine, 1991; Jensen, 1998; Sousa, 2001; Wolfe, 2001) have a clear connection to nurturing the creative potential in students. Intrinsic motivation and emotions affect student learning and creativity as well (Hennessey & Amabile, 1987). The purpose of this study was to discern if a creativity-focused science curriculum for the kindergarteners at a Montessori early learning center could increase creativity in students. This action research study included observations of the students in two classrooms, one using the creativity-focused science curriculum, and the other using the existing curriculum. The data collected for this interpretive study included interviews with the students, surveys and interviews with their parents and teachers, teacher observations, and the administration of Torrance's (1981) Thinking Creatively in Action and Movement (TCAM) test. The interpretation of the data indicated that the enhanced science curriculum played a role in enhancing the creativity of the children in the creativity-focused group. The results of the TCAM (Torrance, 1981) showed a significant increase in scores for the children in the creativity-focused group. The qualitative data revealed a heightened interest in science and the observation of creative traits, processes, and products in the creativity-focused group children. The implications of this study included the need for meaningful

    The paper is a philosophical analysis of experimentation. The philosophical framework of the analysis is the interrogative model of inquiry developed by Hintikka. The basis of the model is explicit and well-formed logic of questions and answers. The framework allows us to formulate a flexible logic of experimentation. In particular, the formulated model can be interpreted realistically. Moreover, the model demonstrates an explicit logic of knowledge acquisition. So, the natural extension of the model is to apply it to an analysis of the learning process.
