Components of complex systems apply across multiple subject areas, and teaching these components may help students build unifying conceptual links. Students, however, often have difficulty learning these components, and limited research exists to understand what types of interventions may best help improve understanding. We investigated 32 high school students' understandings of complex systems components and whether an agent-based simulation could improve their understandings. Pretest and posttest essays were coded for changes in six components to determine whether students showed more expert thinking about the complex system of the Chesapeake Bay watershed. Results showed significant improvement for the components Emergence ( r = .26, p = .03), Order ( r = .37, p = .002), and Tradeoffs ( r = .44, p = .001). Implications include that the experiential nature of the simulation has the potential to support conceptual change for some complex systems components, presenting a promising option for complex systems instruction.

In this article, we begin to lay out a framework and approach for studying how students come to understand complex concepts in rich domains. Grounded in theories of embodied cognition, we advance the view that understanding of complex concepts requires students to practice, over time, the coordination of multiple concepts, and the connection of this system of concepts to situations in the world. Specifically, we explore the role that a teacher's gesture might play in supporting students' coordination of two concepts central to understanding in the domain of statistics: mean and standard deviation. In Study 1 we show that university students who have just taken a statistics course nevertheless have difficulty taking both mean and standard deviation into account when thinking about a statistical scenario. In Study 2 we show that presenting the same scenario with an accompanying gesture to represent variation significantly impacts students' interpretation of the scenario. Finally, in Study 3 we present evidence that instructional videos on the internet fail to leverage gesture as a means of facilitating understanding of complex concepts. Taken together, these studies illustrate an approach to translating current theories of cognition into principles that can guide instructional design.

Science education today has become increasingly focused on research into complex natural, social and technological systems. In this study, we examined the development of high-school biology students' systems understanding of the human body, in a three-year longitudinal study. The development of the students' system understanding was evaluated using the Components Mechanisms Phenomena (CMP) framework for conceptual representation. We coded and analysed the repertory grid personal constructs of 67 high-school biology students at 4 points throughout the study. Our data analysis builds on the assumption that systems understanding entails a perception of all the system categories, including structures within the system (its Components), specific processes and interactions at the macro and micro levels (Mechanisms), and the Phenomena that present the macro scale of processes and patterns within a system. Our findings suggest that as the learning process progressed, the systems understanding of our students became more advanced, moving forward within each of the major CMP categories. Moreover, there was an increase in the mechanism complexity presented by the students, manifested by more students describing mechanisms at the molecular level. Thus, the 'mechanism' category and the micro level are critical components that enable students to understand system-level phenomena such as homeostasis.

2002-06-01
This study explored the effects of Roundhouse diagram construction on a previously low-performing middle school science student's struggles to understand abstract science concepts and principles. It is based on a metacognition-based visual learning model proposed by Wandersee in 1994. Ward and Wandersee introduced the Roundhouse diagram strategy and showed how it could be applied in science education. This article aims at elucidating the process by which Roundhouse diagramming helps learners bootstrap their current understandings to reach the intended meaningful understanding of complex science topics. The main findings of this study are that (a) it is crucial that relevant prior knowledge and dysfunctional alternative conceptions not be ignored during new learning if low-performing science students are to understand science well; (b) as the student's mastery of the Roundhouse diagram construction improved, so did science achievement; and (c) the student's apt choice of concept-related visual icons aided progress toward meaningful understanding of complex science concepts.

The complex nature of climate change science poses special challenges for educators wishing to broaden and deepen student understanding of the climate system and its sensitivity to and impacts upon human activity. Learners have prior knowledge that may limit their perception and processing of the multiple relationships between processes (e.g., feedbacks) that arise in global change science, and these existing mental models serve as the scaffold for all future learning. Because adoption of complex scientific concepts is not likely if instruction includes presentation of information or concepts that are not compatible with the learners’ prior knowledge, providing effective instruction on this complex topic requires learning opportunities that are anchored upon an evaluation of the limitations and inaccuracies of the learners’ existing understandings of the climate system. The formative evaluation that serves as the basis for planning such instruction can also be useful as a baseline against which to evaluate subsequent learning. We will present concept-mapping activities that we have used to assess students’ knowledge and understanding about global climate change in courses that utilized multiple assessment methods including presentations, writings, discussions, and concept maps. The courses in which these activities were completed use a variety of instructional approaches (including standard lectures and lab assignments and a mock summit) to help students understand the inherently interdisciplinary topic of global climate change, its interwoven human and natural causes, and the connections it has with society through a complex range of political, social, technological and economic factors. Two instances of concept map assessment will be presented: one focused on evaluating student understanding of the major components of the climate system and their interconnections, and the other focused on student understanding of the connections between climate change and the global food system. We will discuss how concept mapping can be used to demonstrate evidence of learning and conceptual change, and also how it can be used to provide information about gaps in knowledge and misconceptions students have about the topic.

Using conceptual maps to assess students' climate change understanding and misconceptions
NASA Astrophysics Data System (ADS)
Gautier, C.
2011-12-01
The complex and interdisciplinary nature of climate change science poses special challenges for educators in helping students understand the climate system, and how it is evolving under natural and anthropogenic forcing. Students and citizens alike have existing mental models that may limit their perception and processing of the multiple relationships between processes (e.g., feedback) that arise in global change science, and prevent adoption of complex scientific concepts. Their prior knowledge base serves as the scaffold for all future learning and grasping its range and limitations serves as an important basis upon which to anchor instruction. Different instructional strategies can be adopted to help students understand the inherently interdisciplinary topic of global climate change, its interwoven human and natural causes, and the connections it has with society through a complex range of political, social, technological and economic factors. One assessment method for students' understanding of global climate change with its many uncertainties, whether associated with the workings of the climate system or with respect to social, cultural and economic processes that mediate human responses to changes within the system, is through the use of conceptual maps. When well designed, they offer a representation of students' mental model prior and post instruction. We will present two conceptual mapping activities used in the classroom to assess students' knowledge and understanding about global climate change and uncover misconceptions. For the first one, concept maps will be used to demonstrate evidence of learning and conceptual change, while for the second we will show how conceptual maps can provide information about gaps in knowledge and misconceptions students have about the topic.

Interactive Lecture Demonstrations (ILDs) have been used across introductory university physics as a successful active learning (AL) strategy to improve students' conceptual understanding. We have developed ILDs for more complex topics in our first-year electronics course. In 2006 we began developing ILDs to improve students' conceptual understanding of Operational Amplifiers (OAs) and negative feedback in amplification circuits. The ILDs were used after traditional lecture instruction to help students consolidate their understanding. We developed a diagnostic test, to be administered to students both before and after the ILDs, as a measure of how effective the ILDs were in improving students' understanding.

This paper gives a grounded cognition account of model-based learning of complex scientific knowledge related to socio-scientific issues, such as climate change. It draws on the results from a study of high school students learning about the carbon cycle through computational agent-based models and investigates two questions: First, how do students ground their understanding about the phenomenon when they learn and solve problems with computer models? Second, what are common sources of mistakes in students' reasoning with computer models? Results show that students ground their understanding in computer models in five ways: direct observation, straight abstraction, generalisation, conceptualisation, and extension. Students also incorporate into their reasoning their knowledge and experiences that extend beyond phenomena represented in the models, such as attitudes about unsustainable carbon emission rates, human agency, external events, and the nature of computational models. The most common difficulties of the students relate to seeing the modelled scientific phenomenon and connecting results from the observations with other experiences and understandings about the phenomenon in the outside world. An important contribution of this study is the constructed coding scheme for establishing different ways of grounding, which helps to understand some challenges that students encounter when they learn about complex phenomena with agent-based computer models.

Developing a systems perspective is a commonly cited goal for geosciences courses and programs. This perspective is a powerful tool for critical thinking, problem solving and integrative thinking across and beyond the sciences. In April 2010, a NSF funded ‘On the Cutting Edge’ workshop brought together 45 geoscience faculty, education and cognitive science researchers, and faculty from other STEM and social science disciplines that make use of a complex systems approach. The workshop participants focused on understanding the challenges inherent in developing an understanding of complex systems and the teaching strategies currently in use across the disciplines. These include using models and visualizations to allow students to experiment with complex systems, using projects and problems to give students experience with data and observations derived from a complex system, and using illustrated lectures and discussions and analogies to illuminate the salient aspects of complex systems. The workshop website contains a collection of teaching activities, instructional resources and courses that demonstrate these approaches. The workshop participants concluded that research leading to a clear articulation of what constitutes understanding complex system behavior is needed, as are instruments and performance measures that could be used to assess this understanding. Developing the ability to recognize complex systems and understand their behavior is a significant learning task that cannot be achieved in a single course. Rather it is a type of literacy that should be taught in a progression extending from elementary school to college and across the disciplines. Research defining this progression and its endpoints is needed. Full information about the workshop, its discussions, and resulting collections of courses, activities, references and ideas are available on the workshop website.

Investigating how students communicate tree-thinking
NASA Astrophysics Data System (ADS)
Boyce, Carrie Jo
Learning is often an active endeavor that requires students work at building conceptual understandings of complex topics. Personal experiences, ideas, and communication all play large roles in developing knowledge of and understanding complex topics. Sometimes these experiences can promote formation of scientifically inaccurate or incomplete ideas. Representations are tools used to help individuals understand complex topics. In biology, one way that educators help people understand evolutionary histories of organisms is by using representations called phylogenetic trees. In order to understand phylogenetics trees, individuals need to understand the conventions associated with phylogenies. My dissertation, supported by the Tree-Thinking Representational Competence and Word Association frameworks, is a mixed-methods study investigating the changes in students' tree-reading, representational competence and mental association of phylogenetic terminology after participation in varied instruction. Participants included 128 introductory biology majors from a mid-sized southern research university. Participants were enrolled in either Introductory Biology I, where they were not taught phylogenetics, or Introductory Biology II, where they were explicitly taught phylogenetics. I collected data using a pre- and post-assessment consisting of a word association task and tree-thinking diagnostic (n=128). Additionally, I recruited a subset of students from both courses (n=37) to complete a computer simulation designed to teach students about phylogenetic trees. I then conducted semi-structured interviews consisting of a word association exercise with card sort task, a retrospective pre-assessment discussion, a post-assessment discussion, and interview questions. I found that students who received explicit lecture instruction had a significantly higher increase in scores on a tree-thinking diagnostic than students who did not receive lecture instruction. Students who received both explicit lecture instruction and the computer simulation had a higher level of representational competence and were better able to understand abstract-style phylogenetic trees than students who only completed the simulation. Students who received explicit lecture instruction had a slightly more scientific association of phylogenetic terms than students who received did not receive lecture instruction. My findings suggest that technological instruction alone is not as beneficial as lecture instruction.

Scientists' progress in understanding enzyme specificity uncovered a complex natural phenomenon. However, not all of the currently available biology textbooks seem to be up to date on this progress. Students' understanding of how enzymes work is a core requirement in biochemistry and biology tertiary education. Nevertheless, current pre-college science education does not provide students with enough biochemical background to enable them to understand complex material such as this. To bridge this gap, a multimedia pre-training presentation was prepared to fuel the learner's prior knowledge with discrete facts necessary to understand the presented concept. This treatment is also known to manage intrinsic cognitive load during the learning process. An interactive instructional enzyme model was also built to motivate students to learn about substrate specificity of enzymes. Upon testing the effect of this combined treatment on 111 college students, desirable learning outcomes were found in terms of cognitive load, motivation, and achievement. The multimedia pre-training group reported significantly less intrinsic cognitive load, higher motivation, and demonstrated higher transfer performance than the control and post-training groups. In this study, a statistical mediation model is also proposed to explain how cognitive load and motivation work in concert to foster learning from multimedia pre-training. This type of research goes beyond simple forms of "what works" to a deeper understanding of "how it works", thus enabling informed decisions for multimedia instructional design. Multimedia learning plays multiple roles in science education. Therefore, science learners would be some of the first to benefit from improving multimedia instructional design. Accordingly, complex scientific phenomena can be introduced to college students in a motivating, informative, and cognitively efficient learning environment.

Despite increasing interest in teachers' and students' conceptions of learning and teaching, and how they influence their practice, there are few studies testing the influence of teachers' conceptions on their students' learning. This study tests how teaching conception (TC; with a distinction between direct and constructive) influences students' representations regarding sheet music. Sixty students (8-12 years old) from music conservatories: 30 of them took lessons with teachers with a constructive TC and another 30 with teachers shown to have a direct TC. Children were given a musical comprehension task in which they were asked to select and rank the contents they needed to learn. These contents had different levels of processing and complexity: symbolic, analytical, and referential. Three factorial ANOVAs, two-one-way ANOVAs, and four 2 × 3 repeated-measures ANOVAs were used to analyse the effects of and the interaction between the independent variables TC and class, both for/on total cards selected, their ranking, and each sub-category (the three processing levels). ANOVAs on the selection and ranking of these contents showed that teachers' conceptions seem to mediate significantly in the way the students understand the music. Students from constructive teachers have more complex and deep understanding of music. They select more elements for learning scores than those from traditional teachers. Teaching conception also influences the way in which children rank those elements. No difference exists between the way 8- and 12-year-olds learn scores. Children's understanding of the scores is more complex than assumed in other studies. © 2013 The British Psychological Society.

Students organize scientific knowledge and reason about environmental issues through manipulation of mental models. The nature of the environmental sciences, which are focused on the study of complex, dynamic systems, may present cognitive difficulties to students in their development of authentic, accurate mental models of environmental systems. The inquiry project seeks to develop and assess the coupling of information technology (IT)-based learning with physical models in order to foster rich mental model development of environmental systems in geoscience undergraduate students. The manipulation of multiple representations, the development and testing of conceptual models based on available evidence, and exposure to authentic, complex and ill-constrained problems were the components of investigation utilized to reach the learning goals. Upper-level undergraduate students enrolled in an environmental geology course at Texas A&M University participated in this research which served as a pilot study. Data based on rubric evaluations interpreted by principal component analyses suggest students' understanding of the nature of scientific inquiry is limited and the ability to cross scales and link systems proved problematic. Results categorized into content knowledge and cognition processes where reasoning, critical thinking and cognitive load were driving factors behind difficulties in student learning. Student mental model development revealed multiple misconceptions and lacked complexity and completeness to represent the studied systems. Further, the positive learning impacts of the implemented modules favored the physical model over the IT-based learning projects, likely due to cognitive load issues. This study illustrates the need to better understand student difficulties in solving complex problems when using IT, where the appropriate scaffolding can then be implemented to enhance student learning of the earth system sciences.

Pharmacology is a crucial component of medications administration in nursing, yet nursing students generally find it difficult and self-rate their pharmacology skills as low. To evaluate nursing students learning pharmacology with the Pharmacology Inter-Leaved Learning-Cells environment, a novel approach to modeling biochemical interactions using a multiscale, computer-based model with a complexity perspective based on a small set of entities and simple rules. This environment represents molecules, organelles and cells to enhance the understanding of cellular processes, and combines these cells at a higher scale to obtain whole-body interactions. Sophomore nursing students who learned the pharmacology of diabetes mellitus with the Pharmacology Inter-Leaved Learning-Cells environment (experimental group; n=94) or via a lecture-based curriculum (comparison group; n=54). A quasi-experimental pre- and post-test design was conducted. The Pharmacology-Diabetes-Mellitus questionnaire and the course's final exam were used to evaluate students' knowledge of the pharmacology of diabetes mellitus. Conceptual learning was significantly higher for the experimental than for the comparison group for the course final exam scores (unpaired t=-3.8, p<0.001) and for the Pharmacology-Diabetes-Mellitus questionnaire (U=942, p<0.001). The largest effect size for the Pharmacology-Diabetes-Mellitus questionnaire was for the medication action subscale. Analysis of complex-systems component reasoning revealed a significant difference for micro-macro transitions between the levels (F(1, 82)=6.9, p<0.05). Learning with complexity-based computerized models is highly effective and enhances the understanding of moving between micro and macro levels of the biochemical phenomena, this is then related to better understanding of medication actions. Moreover, the Pharmacology Inter-Leaved Learning-Cells approach provides a more general reasoning scheme for biochemical processes, which enhances pharmacology learning beyond the specific topic learned. The present study implies that deeper understanding of pharmacology will support nursing students' clinical decisions and empower their proficiency in medications administration.

Students generally approach topics in physiology as a series of unrelated phenomena that share few underlying principles. However, if students recognized that the same underlying principles can be used to explain many physiological phenomena, they may gain a more unified understanding of physiological systems. To address this concern, we developed a simple, inexpensive, and easy to build model to demonstrate the underlying principles regarding Starling's Law of the Heart as well as lung and arterial elastic recoil. A model was chosen because models significantly enhance student understanding. Working with models also encourages research-oriented learning and helps our students understand complex ideas. Students are drawn into discussion by the power of learning that is associated with manipulating and thinking about objects. Recognizing that the same underlying principles can be used to explain many physiological phenomena may help students gain a more complete understanding of physiological systems.

Common problems faced in optical comprehensive design experiment and going against the Washington Accord are pointed out. For resolving these problems, an instructional and innovative teaching scheme for Optics Comprehensive Design Experiment is proposed. We would like to understand the student that can improve the hands-on practical ability, theory knowledge understanding ability, complex problem solving ability, engineering application ability, cooperative ability after tracking and researching the student who have attended the class about Optical Comprehensive Design Experiment, We found that there are some problems on the course such as the experiment content vague, the student beginning less time, phase separation theory and engineering application, the experiment content lack of selectivity and so on. So we have made some improvements reference to the Washington Accord for the class teaching plan about Optical Comprehensive Design Experiment. This class must relevant to the engineering basic courses, professional foundation course and the major courses, so far as to the future study and work that which can play a role in inheriting and continuity to the students. The Optical Comprehensive Design Experiment teaching program requires students learning this course to have learnt basic courses like analog electronics technique, digital electronic technique, applied optics and computer and other related courses which students are required to comprehensively utilize. This teaching scheme contains six practical complex engineering problems which are respectively optical system design, light energy meter design, illuminometer design, material refractive index measuring system design, light intensity measuring system design and open design. Establishing the optional experiment and open experiment can provide students with a greater choice and enhance the students' creativity, vivid teaching experimental teachers and enriching contents of experiment can make the experiment more interesting, providing students with more opportunities to conduct experiment and improving students' practical ability with long learning time, putting emphasis on student's understanding of complex engineering problems and the cognitive of the process to solve complex engineering problems with actual engineering problems. Applying the scheme in other courses and improving accordingly will be able to ensure the quality of engineering education. Look forward to offering useful reference for the curriculum system construction in colleges and universities.

Designing Critique for Knowledge Integration
NASA Astrophysics Data System (ADS)
Sato, Mie Elissa
Generating explanations is central to science and has the potential to have a powerful impact on students' conceptual understanding in science instruction. However, improving conceptual understanding by generating explanations is a fraught affair: students may struggle with the sense of false clarity that may arise from generating explanations, fail to detect gaps in their understanding, and dismiss salient information that contradict their beliefs. Critiquing explanations has the potential to counteract these pitfalls by exposing students to alternative ideas to contrast with their own. This dissertation seeks to clarify how to design critique in technology-enhanced science instruction to support students in revising their explanations about scientific phenomena, and in doing so, refining their conceptual understanding. Using the Knowledge Integration framework, I revised two technology-enhanced curriculum units, Plate Tectonics and Global Climate Change, in a design partnership between teachers, researchers, and technologists. I conducted a series of studies with sixth-grade students to investigate the conditions under which guided critique of explanations can support revision. The pilot critique study investigated the impact of the revised Plate Tectonics unit on students' understanding of convection, as well as of a preliminary design of critique where students generated and applied their own criteria for what makes a good explanation in science. The guidance study explored how incorporating a complex selection task that features meta-explanatory criteria into critique supports students in distinguishing among different criteria, as well as how students use peer or expert guidance on their initial explanation during revision. The critique study investigated how designing critique with a complex selection task that features plausible alternative ideas and giving guidance on students' critiques support students in distinguishing among a range of relevant ideas and making productive revisions to their initial explanations. These studies clarify how critique can be designed to help students sort through various ideas in their conceptual repertoire, be they ideas about meta-explanatory criteria or science ideas about a specific phenomenon. The study findings illuminate the challenges of guiding students to examine or re-examine the full range of ideas for knowledge integration. Students struggle to identify salient, missing, or normative ideas in their own or another explanation, and to incorporate their insights in a coherent way through revision. The studies demonstrate that embedding complex selection tasks in critique encourages students to consider a broad range of ideas and supports them in making conceptual revisions of their explanations. The results have implications for the design of critique in technology-enhanced science instruction.

There has been limited research investigating the conceptual development of rehabilitation in speech-language pathology (SLP) students. The aim of this study was to describe SLP students' understanding of rehabilitation following completion of a clinical practicum in a rehabilitation setting. This study was conducted using a qualitative approach according to grounded theory methodology. Semi-structured interviews were conducted with 10 SLP students who had completed a practicum in a rehabilitation setting. Interview data analysis revealed the emergence of five axial categories. Clients becoming teachers was identified as the core category, as the notion that clients were fundamental to students' understanding of rehabilitation occurred reliably throughout the data and related to all other categories. A theoretical model was proposed that demonstrated successive levels of support to students in the acquisition of their understanding of rehabilitation on practicum. Students' understanding of rehabilitation was derived from client-related interactions and factors experienced on practicum in rehabilitation settings. Rehabilitation practicum provided students with a rich and complex learning environment that may facilitate the development of the "core skills" identified for rehabilitation practice.

2017-01-01
A Socratic seminar can be a powerful tool for increasing students’ ability to analyze and interpret data. Most commonly used for text-based discussion, we found that using Socratic seminar to engage students with data contributes to student understanding by allowing them to reason through and process complex information as a group. This approach also provides teachers with insights about student misconceptions and understanding of concepts by listening to the student-driven discussion. This article reports on Socratic seminar in the context of a high school type 2 diabetes curriculum that explores gene and environment interactions. A case study illustrates how Socratic seminar is applied in a classroom and how students engage with the process. General characteristics of Socratic seminar are discussed at the end of the article.

Primary Student-Teachers' Conceptual Understanding of the Greenhouse Effect: A mixed method study
NASA Astrophysics Data System (ADS)
Ratinen, Ilkka Johannes
2013-04-01
The greenhouse effect is a reasonably complex scientific phenomenon which can be used as a model to examine students' conceptual understanding in science. Primary student-teachers' understanding of global environmental problems, such as climate change and ozone depletion, indicates that they have many misconceptions. The present mixed method study examines Finnish primary student-teachers' understanding of the greenhouse effect based on the results obtained via open-ended and closed-form questionnaires. The open-ended questionnaire considers primary student-teachers' spontaneous ideas about the greenhouse effect depicted by concept maps. The present study also uses statistical analysis to reveal respondents' conceptualization of the greenhouse effect. The concept maps and statistical analysis reveal that the primary student-teachers' factual knowledge and their conceptual understanding of the greenhouse effect are incomplete and even misleading. In the light of the results of the present study, proposals for modifying the instruction of climate change in science, especially in geography, are presented.

Without adequate understanding of science, we cannot make responsible personal, regional, national, or global decisions about any aspect of life dealing with science. Better understanding how we learn about science can contribute to improving the quality of our educational experiences. Promoting pathways leading to life-long learning and deep understanding in our world should be a goal for all educators. This dissertation project was a phenomenological investigation into undergraduate understanding and acceptance of scientific theories, including biological evolution. Specifically, student descriptions of conceptual change while learning science theory were recorded and analyzed. These qualitative investigations were preceded by a survey that provided a means of selecting students who had a firmer understanding of science theory. Background information and survey data were collected in an undergraduate biology class at a small, Southern Baptist-affiliated liberal arts school located in south central Kentucky. Responses to questions on the MATE (Rutledge and Warden, 1999) instrument were used to screen students for interviews, which investigated the way by which students came to understand and accept scientific theories. This study identifies some ways by which individuals learn complex science theories, including biological evolution. Initial understanding and acceptance often occurs by the conceptual change method described by Posner et al. (1982). Three principle ways by which an individual may reach a level of understanding and acceptance of science theory were documented in this study. They were conceptual change through application of logic and reasoning; conceptual change through modification of religious views; and conceptual change through acceptance of authoritative knowledge. Development of a deeper, richer understanding and acceptance of complex, multi-faceted concepts such as biological evolution occurs in some individuals by means of conceptual enrichment. Conceptual enrichment occurs through addition of new knowledge, and then examining prior knowledge through the perspective of this new knowledge. In the field of science, enrichment reinforces complex concepts when multiple, convergent lines of supporting evidences point to the same rational scientific conclusion.

The application of a systems approach to assessing biological systems provides hope for a coherent understanding of cell dynamics patterns and their relationship to plant life. This action required the reasoning about complex systems. In other sides, there were a lot of researchers who provided the proof about the instructional successions. They involved the multiple external representations which improved the biological learning. The researcher conducted an investigation using one shoot case study design which involved 30 students in proving that the MERs worksheets could affect the student's achievement of reasoning about complex system. The data had been collected based on test of reasoning about complex system and student's identification result who worked through MERs. The result showed that only partially students could achieve reasoning about system complex, but their MERs skill could support their reasoning ability of complex system. This study could bring a new hope to develop the MERs worksheet as a tool to facilitate the reasoning about complex system.

Although rhetoric abounds in the agricultural education literature regarding the public's dearth of agri-food system literacy, problems arise when establishing educational interventions to help ameliorate illiteracy. Researchers do not fully know what individuals understand about the complex agri-food system. Hence, educational programs and curricula may focus on areas where students already possess well developed and scientifically accurate schemata, while ignoring other areas where incompatible or naive understandings persist. Democratic decisions about complex societal and environmental issues, such as trade-offs of our industrial agri-food system, require individuals to possess understandings of complex interrelationships. This exploratory qualitative study determines what two groups---elementary students and prospective elementary school teachers---understand about selected concepts foundational to agri-food system literacy. To ground the study in current national education curricular standards, a synthesis of both agricultural and science education benchmarks was developed. This helped structure interviews with the study's informants: nine elementary students and nine prospective elementary teachers. Analysis of discourse was based upon a conceptual change methodology. Findings showed that informant background and non-school experiences were linked to agri-food system literacy, while formal, in-school learning was not. For elementary students, high socio-economic status, gardening and not living in urban areas were correlates with literacy; the prospective teacher group exhibited similar trends. Informants understood that food came from farms where plants and animals were raised. For the majority, however, farms were described as large gardens. Additionally, informants lacked a clear understanding of the roles soil and fertilizers play in crop production. Further, few spoke of weeds as competitors with crops for growth requirements. Informants understood that agricultural technologies saved time and reduced labor and were concerned with the immediate impact of agricultural pollution. They, however, did not link their food and fiber consumption with resources use or environmental impact. Additionally, half of the prospective teachers did not understand genetics well enough to discuss how humans engineer life. Notable differences were found between teachers and students in 17% of the elementary benchmarks. Differences between the two groups were found in the elementary students' lack of ability to proffer cause-effect relationships, especially in regard to the use of agricultural technologies.

Concept Maps for Improved Science Reasoning and Writing: Complexity Isn’t Everything
Dowd, Jason E.; Duncan, Tanya; Reynolds, Julie A.
2015-01-01
A pervasive notion in the literature is that complex concept maps reflect greater knowledge and/or more expert-like thinking than less complex concept maps. We show that concept maps used to structure scientific writing and clarify scientific reasoning do not adhere to this notion. In an undergraduate course for thesis writers, students use concept maps instead of traditional outlines to define the boundaries and scope of their research and to construct an argument for the significance of their research. Students generate maps at the beginning of the semester, revise after peer review, and revise once more at the end of the semester. Although some students revised their maps to make them more complex, a significant proportion of students simplified their maps. We found no correlation between increased complexity and improved scientific reasoning and writing skills, suggesting that sometimes students simplify their understanding as they develop more expert-like thinking. These results suggest that concept maps, when used as an intervention, can meet the varying needs of a diverse population of student writers. PMID:26538388
Students Fail to Transfer Knowledge of Chromosome Structure to Topics Pertaining to Cell Division
Newman, Dina L.; Catavero, Christina M.; Wright, L. Kate
2012-01-01
Cellular processes that rely on knowledge of molecular behavior are difficult for students to comprehend. For example, thorough understanding of meiosis requires students to integrate several complex concepts related to chromosome structure and function. Using a grounded theory approach, we have unified classroom observations, assessment data, and in-depth interviews under the theory of knowledge transfer to explain student difficulties with concepts related to chromosomal behavior. In this paper, we show that students typically understand basic chromosome structure but do not activate cognitive resources that would allow them to explain macromolecular phenomena (e.g., homologous pairing during meiosis). To improve understanding of topics related to genetic information flow, we suggest that instructors use pedagogies and activities that prime students for making connections between chromosome structure and cellular processes.

The purpose of this research was to investigate students' understanding of interdependency across grade levels. Interdependency concepts selected for this study included food chains, pollination, and seed dispersal. Children's everyday concepts and scientific concepts across grade levels represented the focus of conceptual understanding. The researcher interviewed a total of 24 students across grade levels, six students each from grades 3, 7, and 10, and 6 college students. Data were collected by means of interviews and card sorts. A constructivist theoretical framework formed the groundwork for presenting the focus of this study and for interpreting the results of the interview data. Results were analyzed on the basis of identifying student responses to interview questions as either everyday concepts or as scientific concepts, along with transition through the zone of proximal development (ZPD) by mediation, as developed by Vygotsky. Results revealed that children across grade levels vary in their everyday and scientific understanding of the three interdependency concepts. Results for seed dispersal showed little evidence of understanding for grade 3, that is, seed dispersal was not within the zone of proximal development (ZPD) for grade 3 students. Students in grades 7 and 10 showed a developing transition within the zone of proximal development from everyday to scientific understanding, and college students demonstrated scientific understanding of seed dispersal. For pollination and food chains, results showed that grades 3, 7, and 10 were in transition from everyday to scientific understanding, and all college students demonstrated scientific understanding. The seed dispersal concept proved more complex than pollination and food chains. The findings of this study have implications for classroom teachers. By understanding the dynamic nature of the ZPD continuum for students, teachers can plan instruction to meet the needs of each student.

Students in Grades 1, 3, and 8 (N = 60) were interviewed while using a planetarium-like setting that allowed the students to demonstrate their ideas about apparent celestial motion both verbally and with their own motions. Though the older students were generally more accurate in many conceptual areas compared with the younger students, in several areas, the eighth-grade students showed no improvement over the third-grade students. The use of kinesthetic learning techniques in a planetarium program was also explored as a method to improve understanding of celestial motion. Pre- and postinterviews were conducted with participants from seven classes of first- and second-grade students (N = 63). Students showed significant improvement in all areas of apparent celestial motion covered by the planetarium program and surpassed the middle school students' understanding of these concepts in most areas. Based on the results of these studies, a learning progression was developed describing how children may progress through successively more complex ways of understanding apparent celestial motion across elementary grades.

In this work, we examine middle school students' understanding of the greenhouse effect and global warming. We designed and refined a technology-enhanced curriculum module called Global Warming: Virtual Earth. In the module activities, students conduct virtual experiments with a visualization of the greenhouse effect. They analyze data and draw conclusions about how individual variables effect changes in the Earth's temperature. They also carry out inquiry activities to make connections between scientific processes, the socio-scientific issues, and ideas presented in the media. Results show that participating in the unit increases students' understanding of the science. We discuss how students integrate their ideas about global climate change as a result of using virtual experiments that allow them to explore meaningful complexities of the climate system.

Biological systems and living processes involve a complex interplay of biochemicals and macromolecular structures that can be challenging for undergraduate students to comprehend and, thus, misconceptions abound. Protein synthesis, or translation, is an example of a biological process for which students often hold many misconceptions. This article describes an exercise that was developed to illustrate the process of translation using simple objects to represent complex molecules. Animations, 3D physical models, computer simulations, laboratory experiments and classroom lectures are also used to reinforce the students' understanding of translation, but by focusing on the simple manipulatives in this exercise, students are better able to visualize concepts that can elude them when using the other methods. The translation exercise is described along with suggestions for background material, questions used to evaluate student comprehension and tips for using the manipulatives to identify common misconceptions.

Students have to be educated in theoretical and practical matters. Only one of them does not allow attacking complex problems in research, development, and management. After their study, students should be able to design, construct and analyze technical problems at highest levels of complexity. Who never experienced the difficulty of setting up measurements will not be able to understand, plan and manage such complex tasks in her/his future career. At EPFL a course was developed for bachelor education and is based on three pillars: concrete actions (enactive) to be done by the students, a synthesis of their work by writing a report (considered as the iconic part) and inputs from the teacher to generalize the findings and link it to a possible complete abstract description (symbolic). Intensive tutoring allowed an intermodal transfer between these categories. This EIS method originally introduced by Jerome Bruner for small children is particular well adapted for engineer education for which theoretical understanding often is not enough. The symbiosis of ex-cathedra lecture and practical work in a classroom-like situation presents an innovative step towards integrated learning that complements perfectly more abstract course principles like online courses.

2016-01-01
The goal of our study was to track changes in student understanding of the central dogma of molecular biology before and after taking a genetics course. Concept maps require the ability to synthesize new information into existing knowledge frameworks, and so the hypothesis guiding this study was that student performance on concept maps reveals specific central dogma misconceptions gained, lost, and retained by students. Students in a genetics course completed pre- and posttest concept mapping tasks using terms related to the central dogma. Student maps increased in complexity and validity, indicating learning gains in both content and complexity of understanding. Changes in each of the 351 possible connections in the mapping task were tracked for each student. Our students did not retain much about the central dogma from their introductory biology courses, but they did move to more advanced levels of understanding by the end of the genetics course. The information they retained from their introductory courses focused on structural components (e.g., protein is made of amino acids) and not on overall mechanistic components (e.g., DNA comes before RNA, the ribosome makes protein). Students made the greatest gains in connections related to transcription, and they resolved the most prior misconceptions about translation. These concept-mapping tasks revealed that students are able to correct prior misconceptions about the central dogma during an intermediate-level genetics course. From these results, educators can design new classroom interventions to target those aspects of this foundational principle with which students have the most trouble. PMID:28101260

This study documented the changes in understanding a class of eighth grade high school-level biology students experienced through a biology unit introducing genetics. Learning profiles for 55 students were created using concept maps and interviews as qualitative and quantitative instruments. The study provides additional support to the theory of learning progressions called for by experts in the field. The students' learning profiles were assessed to determine the alignment with a researcher-developed learning profile. The researcher-developed learning profile incorporated the learning progressions published in the Next Generation Science Standards, as well as current research in learning progressions for 5-10th grade students studying genetics. Students were found to obtain understanding of the content in a manner that was nonlinear, even circuitous. This opposes the prevailing interpretation of learning progressions, that knowledge is ascertained in escalating levels of complexity. Learning progressions have implications in teaching sequence, assessment, education research, and policy. Tracking student understanding of other populations of students would augment the body of research and enhance generalizability.

The delivery of concepts in studying Biology often represented through a diagram to easily makes student understand about Biology material. One way to knowing the students’ understanding about diagram can be seen from causal relationship that is constructed by student in the propositional network representation form. This research reveal the trend of students’ propositional network representation patterns when confronted with convention diagram. This descriptive research involved 32 students at one of senior high school in Bandung. The research data was acquired by worksheet that was filled by diagram and it was developed according on information processing standards. The result of this research revealed three propositional network representation patterns are linear relationship, simple reciprocal relationship, and complex reciprocal relationship. The dominating pattern is linear form that is simply connect some information components in diagram by 59,4% students, the reciprocal relationship form with medium level by 28,1% students while the complex reciprocal relationship by only 3,1% and the rest was students who failed to connect information components by 9,4%. Based on results, most of student only able to connect information components on the picture in linear form and a few student constructing reciprocal relationship between information components on convention diagram.

Creating a classroom environment that fosters a productive learning experience and engages students in the learning process is a complex endeavor. A classroom environment is dynamic and requires a unique synergy among students, teacher, classroom artifacts and events to achieve robust understanding and knowledge integration. This dissertation addresses this complex issue by developing, implementing, and investigating the simple machines learning environment (SIMALE) to support students' mechanical reasoning and understanding. SIMALE was designed to support reflection, collaborative learning, and to engage students in generative learning through multiple representations of concepts and successive experimentation and design activities. Two key components of SIMALE are an original web-based software tool and hands-on Lego activities. A research study consisting of three treatment groups was created to investigate the benefits of hands-on and web-based computer activities on students' analytic problem solving ability, drawing/modeling ability, and conceptual understanding. The study was conducted with two populations of students that represent a diverse group with respect to gender, ethnicity, academic achievement and social/economic status. One population of students in this dissertation study participated from the Mathematics, Engineering, and Science Achievement (MESA) program that serves minorities and under-represented groups in science and mathematics. The second group was recruited from the Academic Talent Development Program (ATDP) that is an academically competitive outreach program offered through the University of California at Berkeley. Results from this dissertation show success of the SIMALE along several dimensions. First, students in both populations achieved significant gains in analytic problem solving ability, drawing/modeling ability, and conceptual understanding. Second, significant differences that were found on pre-test measures were eliminated on post-test measures. Specifically, female students scored significantly lower than males on the overall pre-tests but scored as well as males on the same post-test measures. MESA students also scored significantly lower than ATDP students on pre-test measures but both populations scored equally well on the post-tests. This dissertation has therefore shown the SIMALE to support a collaborative, reflective, and generative learning environment. Furthermore, the SIMALE clearly contributes to students' mechanical reasoning and understanding of simple machines concepts for a diverse population of students.

Six Classroom Exercises to Teach Natural Selection to Undergraduate Biology Students
Kalinowski, Steven T.; Leonard, Mary J.; Andrews, Tessa M.; Litt, Andrea R.
2013-01-01
Students in introductory biology courses frequently have misconceptions regarding natural selection. In this paper, we describe six activities that biology instructors can use to teach undergraduate students in introductory biology courses how natural selection causes evolution. These activities begin with a lesson introducing students to natural selection and also include discussions on sexual selection, molecular evolution, evolution of complex traits, and the evolution of behavior. The set of six topics gives students the opportunity to see how natural selection operates in a variety of contexts. Pre- and postinstruction testing showed students’ understanding of natural selection increased substantially after completing this series of learning activities. Testing throughout this unit showed steadily increasing student understanding, and surveys indicated students enjoyed the activities. PMID:24006396
Competencies to enable learning-focused clinical supervision: a thematic analysis of the literature.
Pront, Leeanne; Gillham, David; Schuwirth, Lambert W T
2016-04-01
Clinical supervision is essential for development of health professional students and widely recognised as a significant factor influencing student learning. Although considered important, delivery is often founded on personal experience or a series of predetermined steps that offer standardised behavioural approaches. Such a view may limit the capacity to promote individualised student learning in complex clinical environments. The objective of this review was to develop a comprehensive understanding of what is considered 'good' clinical supervision, within health student education. The literature provides many perspectives, so collation and interpretation were needed to aid development and understanding for all clinicians required to perform clinical supervision within their daily practice. A comprehensive thematic literature review was carried out, which included a variety of health disciplines and geographical environments. Literature addressing 'good' clinical supervision consists primarily of descriptive qualitative research comprising mostly small studies that repeated descriptions of student and supervisor opinions of 'good' supervision. Synthesis and thematic analysis of the literature resulted in four 'competency' domains perceived to inform delivery of learning-focused or 'good' clinical supervision. Domains understood to promote student learning are co-dependent and include 'to partner', 'to nurture', 'to engage' and 'to facilitate meaning'. Clinical supervision is a complex phenomenon and establishing a comprehensive understanding across health disciplines can influence the future health workforce. The learning-focused clinical supervision domains presented here provide an alternative perspective of clinical supervision of health students. This paper is the first step in establishing a more comprehensive understanding of learning-focused clinical supervision, which may lead to development of competencies for clinical supervision. © 2016 John Wiley & Sons Ltd.
Learning to manage complexity through simulation: students' challenges and possible strategies.
Gormley, Gerard J; Fenwick, Tara
2016-06-01
Many have called for medical students to learn how to manage complexity in healthcare. This study examines the nuances of students' challenges in coping with a complex simulation learning activity, using concepts from complexity theory, and suggests strategies to help them better understand and manage complexity.Wearing video glasses, participants took part in a simulation ward-based exercise that incorporated characteristics of complexity. Video footage was used to elicit interviews, which were transcribed. Using complexity theory as a theoretical lens, an iterative approach was taken to identify the challenges that participants faced and possible coping strategies using both interview transcripts and video footage.Students' challenges in coping with clinical complexity included being: a) unprepared for 'diving in', b) caught in an escalating system, c) captured by the patient, and d) unable to assert boundaries of acceptable practice.Many characteristics of complexity can be recreated in a ward-based simulation learning activity, affording learners an embodied and immersive experience of these complexity challenges. Possible strategies for managing complexity themes include: a) taking time to size up the system, b) attuning to what emerges, c) reducing complexity, d) boundary practices, and e) working with uncertainty. This study signals pedagogical opportunities for recognizing and dealing with complexity.

Complex systems surround us, and as Sabelli (2006) has argued, understanding complex systems is a critical component of science literacy. Understanding natural and designed systems are also prominent in the new draft science standards (NRC, 2010) and therefore of growing importance in the science classroom. Our work has focused on promoting an understanding of one complex natural system, aquatic ecosystems, which given current events, is fast becoming a requisite for informed decision-making as citizens (Jordan et al. 2008). Learners have difficulty understanding many concepts related to complex natural systems (e.g., Hmelo-Silver, Marathe, & Liu, 2007; Jordan, Gray, Liu, Demeter, & Hmelo-Silver, 2009). Studies of how students think about complex ecological systems (e.g; Hmelo-Silver, Marathe, & Liu, 2007; Hogan, 2000, Hogan & Fisherkeller, 1996: Covitt & Gunkel, 2008) have revealed difficulties in thinking beyond linear flow, single causality, and visible structure. Helping students to learn about ecosystems is a complex task that requires providing opportunities for students to not only engage directly with ecosystems but also with resources that provide relevant background knowledge and opportunities for learners to make their thinking visible. Both tasks can be difficult given the large spatial and temporal scales on which ecosystems operate. Additionally, visible components interact with often invisible components which can obscure ecosystem processes for students. Working in the context of aquatic ecosystems, we sought to provide learners with representations and simulations that make salient the relationship between system components. In particular, we provided learners with opportunities to experience both the micro-level and macro-level phenomena that are key to understanding ecosystems (Hmelo-Silver, Liu, Gray, & Jordan, submitted; Liu & Hmelo-Silver, 2008; Jacobson & Wilensky, 2006). To accomplish this, we needed to help learners make connections across the levels of ecosystems. A big part of this is making phenomena accessible to their experience. We accomplished through the use of physical models and computers simulations at different scale. In an effort to promote a coherent understanding in our learners, we sought to develop tools that can provide dynamic feedback that will enable them to modify, enrich, and repair their mental models as needed (e.g., Roschelle, 1996). Additionally, we also wanted to develop a conceptual representation that can be used across multiple ecosystems to prepare students to learn about new systems in the future (Bransford & Schwartz, 1999). Our approach to this has been to use the structure-behavior-function (SBF) conceptual representation (Liu & Hmelo-Silver, 2009; Vattam et al., in press). Often, learning life science is about learning the names of structures. One of our design principles is to ensure instruction emphasizes the behaviors (or mechanisms) of systems as well as the functions (the system outputs) in addition to the structures. We have used simulations to help make behaviors and functions visible and a modeling tool that supports students in thinking about the SBF conceptual representation. In this presentation, we will report on the results of classroom interventions and the lessons learned.

Science classroom inquiry (SCI) simulations: a novel method to scaffold science learning.
Peffer, Melanie E; Beckler, Matthew L; Schunn, Christian; Renken, Maggie; Revak, Amanda
2015-01-01
Science education is progressively more focused on employing inquiry-based learning methods in the classroom and increasing scientific literacy among students. However, due to time and resource constraints, many classroom science activities and laboratory experiments focus on simple inquiry, with a step-by-step approach to reach predetermined outcomes. The science classroom inquiry (SCI) simulations were designed to give students real life, authentic science experiences within the confines of a typical classroom. The SCI simulations allow students to engage with a science problem in a meaningful, inquiry-based manner. Three discrete SCI simulations were created as website applications for use with middle school and high school students. For each simulation, students were tasked with solving a scientific problem through investigation and hypothesis testing. After completion of the simulation, 67% of students reported a change in how they perceived authentic science practices, specifically related to the complex and dynamic nature of scientific research and how scientists approach problems. Moreover, 80% of the students who did not report a change in how they viewed the practice of science indicated that the simulation confirmed or strengthened their prior understanding. Additionally, we found a statistically significant positive correlation between students' self-reported changes in understanding of authentic science practices and the degree to which each simulation benefitted learning. Since SCI simulations were effective in promoting both student learning and student understanding of authentic science practices with both middle and high school students, we propose that SCI simulations are a valuable and versatile technology that can be used to educate and inspire a wide range of science students on the real-world complexities inherent in scientific study.

The opportunities and challenges of guided inquiry science for students with special needs
NASA Astrophysics Data System (ADS)
Miller, Marianne
Research in science education has been conducted with various goals for instruction. Four outcomes identified include: immediate and delayed recall, literal comprehension, science skills and processes, and conceptual understanding. The promise of developing important thinking skills exists for all students if science instruction is designed to teach students the products of science and the principled process of inquiry. Guided inquiry science seeks to develop conceptual understanding through the pursuit of meaningful questions using scientific problem solving to conduct investigations that are thoughtfully generated and evaluated. Using a social constructivist perspective, this study examines the learning experiences of four students, identified by their teachers as learning disabled or underachieving. Four case studies are presented of the students' participation in a guided inquiry investigation of the behavior of light. Measures of conceptual understanding included pre- and post-instruction assessments, interviews, journal writing, videotapes, and fieldnotes. All four students demonstrated improved conceptual understanding of light. Five patterns of relationships influenced the development of the students' thinking. First, differences in the culture of the two classrooms altered the learning environment, Second, the nature of teacher interaction with the target students affected conceptual understanding. Third, interactions with peers modified the learning experiences for the identified students. Fourth, the conceptual and procedural complexity of the tasks increased the tendency for the students to lose focus. Finally, the literacy requirements of the work were challenging for these students.

In classroom, scientific contents are increasingly communicated through visual forms of representations. Students' learning outcomes rely on their ability to read and understand pictorial information. Understanding pictorial information in biology requires cognitive effort and can be challenging to students. Yet evidence-based knowledge about students' visual reading strategies during the process of understanding pictorial information is pending. Therefore, 42 students at the age of 14-15 were asked to think aloud while trying to understand visual representations of the blood circulatory system and the patellar reflex. A category system was developed differentiating 16 categories of cognitive activities. A Principal Component Analysis revealed two underlying patterns of activities that can be interpreted as visual reading strategies: 1. Inferences predominated by using a problem-solving schema; 2. Inferences predominated by recall of prior content knowledge. Each pattern consists of a specific set of cognitive activities that reflect selection, organisation and integration of pictorial information as well as different levels of expertise. The results give detailed insights into cognitive activities of students who were required to understand the pictorial information of complex organ systems. They provide an evidence-based foundation to derive instructional aids that can promote students pictorial-information-based learning on different levels of expertise.

Health care systems in Norway and the western world have experienced extensive changes due to patients living longer with complex conditions that require coordinated care. A Norwegian healthcare reform has led to significant restructuring in service delivery as a devolution of services to municipalities. Partners from three rural healthcare services, students from four professional programmes, and one lecturer from each of the professional programmes used a collaborative approach to obtain new knowledge through interprofessional practice. Using an action research design, the research group facilitated democratic processes through dialogues with healthcare services and students. The design is visualised as a cyclical process in which each cycle contributes to improvements, innovations, and increased understanding. A total of 32 students and 3 supervisors were interviewed before and after the clinical practice experiences. Fieldwork was conducted during three clinical periods. Interprofessional student groups formed small healthcare teams and assessed patients with chronic and long-term conditions. Students prepared and negotiated patient follow-up. The teams' responsibilities led to reflective practices that enhanced their professional knowledge. The teams achieved a new understanding of patient situations, which influenced "second opinions" for patients with complex conditions and led to innovative practices. The change in perception of patient needs led to a changed professional approach. The students' perceptions changed as they learned from and about each other and in collaboration with the health service; this led to more coordinated care of patients with complex conditions. Interprofessional learning in community settings provided a platform to improve both healthcare education and rural healthcare services. This research contributes to knowledge of how students' placement in interprofessional teams can enhance students learning from, with and about each other. The student teams promoted new ways of approaching and delivering complex patient treatment and care in community healthcare service. Collaborative partnerships in interprofessional learning have potential in the wider international arena as a means for practice improvement. Copyright © 2016 Elsevier Ltd. All rights reserved.

Advances in science education research have the potential to improve the way students learn to perform scientific interpretations and understand science concepts. We developed active, collaborative activities to teach skills in manipulating flow cytometry data using FlowJo software. Undergraduate students were given compensated clinical flow cytometry listmode output (FCS) files and asked to design a gating strategy to diagnose patients with different hematological malignancies on the basis of their immunophenotype. A separate cohort of research trainees was given uncompensated data files on which they performed their own compensation, calculated the antibody staining index, designed a sequential gating strategy, and quantified rare immune cell subsets. Student engagement, confidence, and perceptions of flow cytometry were assessed using a survey. Competency against the learning outcomes was assessed by asking students to undertake tasks that required understanding of flow cytometry dot plot data and gating sequences. The active, collaborative approach allowed students to achieve learning outcomes not previously possible with traditional teaching formats, for example, having students design their own gating strategy, without forgoing essential outcomes such as the interpretation of dot plots. In undergraduate students, favorable perceptions of flow cytometry as a field and as a potential career choice were correlated with student confidence but not the ability to perform flow cytometry data analysis. We demonstrate that this new pedagogical approach to teaching flow cytometry is beneficial for student understanding and interpretation of complex concepts. It should be considered as a useful new method for incorporating complex data analysis tasks such as flow cytometry into curricula. Copyright © 2016 The American Physiological Society.

How Earth Educators Can Help Students Develop a Holistic Understanding of Sustainability

Curren, R. R.; Metzger, E. P.
2017-12-01
With their expert understanding of planetary systems, Earth educators play a pivotal role in helping students understand the scientific dimensions of solution-resistant ("wicked") challenges to sustainability that arise from complex interactions between intertwined and co-evolving natural and human systems. However, teaching the science of sustainability in isolation from consideration of human values and social dynamics leaves students with a fragmented understanding and obscures the underlying drivers of unsustainability. Geoscience instructors who wish to address sustainability in their courses may feel ill-equipped to engage students in investigation of the fundamental nature of sustainability and its social and ethical facets. This presentation will blend disciplinary perspectives from Earth system science, philosophy, psychology, and anthropology to: 1) outline a way to conceptualize sustainability that synthesizes scientific, social, and ethical perspectives and 2) provide an overview of resources and teaching strategies designed to help students connect science content to the socio-political dimensions of sustainability through activities and assignments that promote active learning, systems thinking, reflection, and collaborative problem-solving.
Students' Energy Concepts at the Transition Between Primary and Secondary School

Opitz, Sebastian T.; Harms, Ute; Neumann, Knut; Kowalzik, Kristin; Frank, Arne

Energy is considered both a core idea and a crosscutting concept in science education. A thorough understanding of the energy concept is thought to help students learn about other (related) concepts within and across science subjects, thereby fostering scientific literacy. This study investigates students' progression in understanding the energy concept in biological contexts at the transition from primary to lower secondary school by employing a quantitative, cross-sectional study in grades 3-6 ( N = 540) using complex multiple-choice items. Based on a model developed in a previous study, energy concepts were assessed along four aspects of energy: (1) forms and sources of energy, (2) transfer and transformation, (3) degradation and dissipation, and (4) energy conservation. Two parallel test forms (A and B) indicated energy concept scores to increase significantly by a factor of 2.3 (A)/1.7 (B) from grade 3 to grade 6. Students were observed to progress in their understanding of all four aspects of the concept and scored highest on items for energy forms. The lowest scores and the smallest gain across grades were found for energy conservation. Based on our results, we argue that despite numerous learning opportunities, students lack a more integrated understanding of energy at this stage, underlining the requirement of a more explicit approach to teaching energy to young learners. Likewise, more interdisciplinary links for energy learning between relevant contexts in each science discipline may enable older students to more efficiently use energy as a tool and crosscutting concept with which to analyze complex content.

The Earth's climate system includes complex behavior and interconnections with other Earth spheres that present challenges to student learning. To better understand these unique challenges, we have conducted experiments with high-school and introductory level college students to determine how information pertaining to the connections between the Earth's atmospheric system and the other Earth spheres (e.g., hydrosphere and cryosphere) are processed. Specifically, we include psychomotor tests (e.g., eye-tracking) and open-ended questionnaires in this research study, where participants were provided scientific images of the Earth (e.g., global precipitation and ocean and atmospheric currents), eye-tracked, and asked to provide causal or relational explanations about the viewed images. In addition, the students engaged in on-line modules (http://serc.carleton.edu/eslabs/climate/index.html) focused on Earth system science as training activities to address potential cognitive barriers. The developed modules included interactive media, hands-on lessons, links to outside resources, and formative assessment questions to promote a supportive and data-rich learning environment. Student eye movements were tracked during engagement with the materials to determine the role of perception and attention on understanding. Students also completed a conceptual questionnaire pre-post to determine if these on-line curriculum materials assisted in their development of connections between Earth's atmospheric system and the other Earth systems. The pre-post results of students' thinking about climate change concepts, as well as eye-tracking results, will be presented.

Among the most important concepts in environmental science learning is the structure and dynamics of coupled human and natural systems (CHANS). But the fundamental epistemology for understanding CHANS requires systems thinking, interdisciplinarity, and complexity. Although the Next Generation Science Standards mandate connecting ideas across disciplines and systems, traditional approaches to education do not provide more than superficial understanding of this concept. Informal science learning institutions have a key role in bridging gaps between the reductive nature of classroom learning and contemporary data-driven science. The New York Hall of Science, in partnership with Design I/O and Columbia University's Center for International Earth Science Information Network, has developed an approach to immerse visitors in complex human nature interactions and provide opportunities for those of all ages to elicit and notice environmental consequences of their actions. Connected Worlds is a nearly 1,000 m2 immersive, playful environment in which students learn about complexity and interconnectedness in ecosystems and how ecosystems might respond to human intervention. It engages students through direct interactions with fanciful flora and fauna within and among six biomes: desert, rainforest, grassland, mountain valley, reservoir, and wetlands, which are interconnected through stocks and flows of water. Through gestures and the manipulation of a dynamic water system, Connected Worlds enables students, teachers, and parents to experience how the ecosystems of planet Earth are connected and to observe relationships between the behavior of Earth's inhabitants and our shared world. It is also a cyberlearning platform to study how visitors notice and scaffold their understanding of complex environmental processes and the responses of these processes to human intervention, to help inform the improvement of education practices in complex environmental science.

After graduation, nurse practitioner students are expected to be capable of providing complex, evidence-based nursing care independently, combined with standardized medical care. The students who follow work-study programs have to develop their competencies in a healthcare environment dominated by efficiency policies. This study aims to explore nurse practitioner students' perceptions of their professional responsibility for patient care. This qualitative interpretative study entails a content analysis of 46 reflective case studies written by nurse practitioner students. The students felt responsible for the monitoring of patients' health status, attending to psychosocial problems, emphasizing compliance, and optimizing the family's role as informal caregivers. At the same time, students struggled to understand the complexities of their patients' needs, and they had difficulty applying their knowledge and skills to complex medical, psychological, and social problems. The students' perceptions of their new responsibility were characterized by a strong focus on curative care, while psychosocial components of health and illness concerns were often overlooked. The students experienced difficulties in meeting the criteria of advanced practice nursing described in the Dutch competency framework. Copyright © 2015 Elsevier Ltd. All rights reserved.
Evolution in students' understanding of thermal physics with increasing complexity

Langbeheim, Elon; Safran, Samuel A.; Livne, Shelly; Yerushalmi, Edit
2013-12-01
We analyze the development in students’ understanding of fundamental principles in the context of learning a current interdisciplinary research topic—soft matter—that was adapted to the level of high school students. The topic was introduced in a program for interested 11th grade high school students majoring in chemistry and/or physics, in an off-school setting. Soft matter was presented in a gradual increase in the degree of complexity of the phenomena as well as in the level of the quantitative analysis. We describe the evolution in students’ use of fundamental thermodynamics principles to reason about phase separation—a phenomenon that is ubiquitous in soft matter. In particular, we examine the impact of the use of free energy analysis, a common approach in soft matter, on the understanding of the fundamental principles of thermodynamics. The study used diagnostic questions and classroom observations to gauge the student’s learning. In order to gain insight on the aspects that shape the understanding of the basic principles, we focus on the responses and explanations of two case-study students who represent two trends of evolution in conceptual understanding in the group. We analyze changes in the two case studies’ management of conceptual resources used in their analysis of phase separation, and suggest how their prior knowledge and epistemological framing (a combination of their personal tendencies and their prior exposure to different learning styles) affect their conceptual evolution. Finally, we propose strategies to improve the instruction of these concepts.

The main objective of this study is to construct a Lakatosian teaching strategy that can facilitate conceptual change in students'' understanding of chemical equilibrium. The strategy is based on the premise that cognitive conflicts must have been engendered by the students themselves in trying to cope with different problem solving strategies. Results obtained (based on Venezuelan freshman students) show that the performance of the experimental group of students was generally better (especially on the immediate post tests) than that of the control group. It is concluded that a conceptual change teaching strategy must take into consideration the following aspects: a) core beliefs of the students in the topic (cf. ''hard core'', Lakatos 1970); b) exploration of the relationship between core beliefs and student alternative conceptions (misconceptions); c) cognitive complexity of the core belief can be broken down into a series of related and probing questions; d) students resist changes in their core beliefs by postulating ''auxiliary hypotheses'' in order to resolve their contradictions; e) students'' responses based on their alternative conceptions must be considered not as wrong, but rather as models, perhaps in the same sense as used by scientists to break the complexity of a problem; and f) students'' misconceptions be considered as alternative conceptions (theories) that compete with the present scientific theories and at times recapitulate theories scientists held in the past.
Moving alcohol prevention research forward-Part I: introducing a complex systems paradigm.
Apostolopoulos, Yorghos; Lemke, Michael K; Barry, Adam E; Lich, Kristen Hassmiller
2018-02-01
The drinking environment is a complex system consisting of a number of heterogeneous, evolving and interacting components, which exhibit circular causality and emergent properties. These characteristics reduce the efficacy of commonly used research approaches, which typically do not account for the underlying dynamic complexity of alcohol consumption and the interdependent nature of diverse factors influencing misuse over time. We use alcohol misuse among college students in the United States as an example for framing our argument for a complex systems paradigm. A complex systems paradigm, grounded in socio-ecological and complex systems theories and computational modeling and simulation, is introduced. Theoretical, conceptual, methodological and analytical underpinnings of this paradigm are described in the context of college drinking prevention research. The proposed complex systems paradigm can transcend limitations of traditional approaches, thereby fostering new directions in alcohol prevention research. By conceptualizing student alcohol misuse as a complex adaptive system, computational modeling and simulation methodologies and analytical techniques can be used. Moreover, use of participatory model-building approaches to generate simulation models can further increase stakeholder buy-in, understanding and policymaking. A complex systems paradigm for research into alcohol misuse can provide a holistic understanding of the underlying drinking environment and its long-term trajectory, which can elucidate high-leverage preventive interventions. © 2017 Society for the Study of Addiction.

Based on a sociology research-action project, this article analyses the specific issue of return to school of high school students with cancer. Three detailed cases, illustrating the global results of the study, are presented to highlight the academic trajectories of these students. This situation has a particular impact on juvenile sociability. Moreover, the education of these students does not comply with French educational standards and is very complex for professionals. Finally, social inequalities in education are reinforced by the experience of serious illness, as pedagogical negotiations are even more complex due to the fact that families are not familiar with school practices.
Teaching Sustainability in Introductory Physics
NASA Astrophysics Data System (ADS)
Coffey, David
Guiding students to a better understanding of sustainability is a key part of a modern undergraduate education. Since 2014, Warren Wilson College has incorporated a sustainability component into our introductory physics courses. Students perform energy audits and abatement plans for a business or building. In the process, students strengthen their competency with basic physics concepts including energy, power, units, and conservation of energy but also gain an appreciation of the complexity of sustainability as well as the need for quantitative understanding. These courses are taught to mostly undergraduate science majors. The challenges and opportunities of incorporating such a broad and personalized educational component will be discussed.

Schwartz, Pete
2017-05-01
"Parallel" pedagogy covers the four mechanics concepts of momentum, energy, forces, and kinematics simultaneously instead of building each concept on an understanding of the previous one. Course content is delivered through interactive videos, allowing class time for group work and student-centered activities. We start with simple examples, building complexity throughout the course with the introduction of springs, two dimensions, vectors, energy diagrams, universal gravitation, and rotation. Success means that students ponder underlying physics concepts rather than hunt for formulas. Surveys indicate that students accept this learning model well and have considerable improvement in applied conceptual understanding.
Models of conceptual understanding in human respiration and strategies for instruction
NASA Astrophysics Data System (ADS)
Rea-Ramirez, Mary Anne
Prior research has indicated that students of all ages show little understanding of respiration beyond breathing in and out and the need for air to survive. This occurs even after instruction with alternative conceptions persisting into adulthood. Whether this is due to specific educational strategies or to the level of difficulty in understanding a complex system is an important question. The purpose of this study was to obtain a deeper understanding of middle school students' development of mental models of human respiration. The study was composed of two major parts, one concerned with documenting and analyzing how students learn, and one concerned with measuring the effect of teaching strategies. This was carried out through a pre-test, "learning aloud" case studies in which students engaged in one-on-one tutoring interviews with the researcher, and a post-test. Transcript data from the intervention and post-test indicates that all students in this study were successful in constructing mental models of a complex concept, respiration, and in successfully applying these mental models to transfer problems. Differences in the pretest and posttest means were on the order of two standard deviations in size. While findings were uncovered in the use of a variety of strategies, possibly most interesting are the new views of analogies as an instructional strategy. Some analogies appear to be effective in supporting construction of visual/spatial features. Providing multiple, simple analogies that allow the student to construct new models in small steps, using student generated analogies, and using analogies to determine prior knowledge may also increase the effectiveness of analogies. Evidence suggested that students were able to extend the dynamic properties of certain analogies to the dynamics of the target conception and that this, in turn, allowed students to use the new models to explain causal relationships and give new function to models. This suggests that construction of causal, dynamic mental models is supported by the use of analogies containing dynamic and causal relationships.

Refining a learning progression of energy
NASA Astrophysics Data System (ADS)
Yao, Jian-Xin; Guo, Yu-Ying; Neumann, Knut
2017-11-01
This paper presents a revised learning progression for the energy concept and initial findings on diverse progressions among subgroups of sample students. The revised learning progression describes how students progress towards an understanding of the energy concept along two progress variables identified from previous studies - key ideas about energy and levels of conceptual development. To assess students understanding with respect to the revised learning progression, we created a specific instrument, the Energy Concept Progression Assessment (ECPA) based on previous work on assessing students' understanding of energy. After iteratively refining the instrument in two pilot studies, the ECPA was administered to a total of 4550 students (Grades 8-12) from schools in two districts in a major city in Mainland China. Rasch analysis was used to examine the validity of the revised learning progression and explore factors explaining different progressions. Our results confirm the validity of the four conceptual development levels. In addition, we found that although following a similar progression pattern, students' progression rate was significantly influenced by environmental factors such as school type. In the discussion of our findings, we address the non-linear and complex nature of students' progression in understanding energy. We conclude with illuminating our research's implication for curriculum design and energy teaching.
Partnering to enhance interprofessional service-learning innovations and addictions recovery.
Mihalynuk, T V; Soule Odegard, P; Kang, R; Kedzierski, M; Johnson Crowley, N
2007-11-01
Service-learning programs are reported to benefit students, faculty, higher education institutions, community agencies and the relationships among these groups. An interprofessional service-learning paradigm may strengthen these benefits. Community settings can expose students to social and cultural determinants of health, in addition to those biomedical determinants more commonly addressed in health sciences curricula. These experiences can also enhance student understanding of the complexities underlying treatment and prevention of modern health problems, particularly chronic diseases. The purpose of this initiative was to create and deliver interprofessional service-learning innovations that would enhance student learning and addictions recovery. To address this initiative, the University of Washington's Health Science Partnerships in Interdisciplinary Clinical Education (HSPICE) and the Salvation Army Adult Rehabilitation Center (ARC) began a community-campus partnership in 1997. Innovations took into account student educational objectives established by HSPICE which included: participation in interdisciplinary teams, in conjunction with community partners to identify and reduce population-based health issues, realization and articulation of biases regarding issues faced by the participating community, acquiring an understanding of the broader determinants of health and developing an understanding of why the complexity of population health requires interdisciplinary strategies for cost effectiveness. Findings are reported from evaluations, needs assessments and ongoing feedback of men recovering from addictions, as applied to health education materials and presentations developed for the ARC. Future directions are highlighted, including the need for further research and evaluation efforts aimed at rigorously assessing cost savings and student knowledge, skills and cultural sensitivity, among others.

"Touching Triton": Building Student Understanding of Complex Disease Risk.
Loftin, Madelene; East, Kelly; Hott, Adam; Lamb, Neil
2016-01-01
Life science classrooms often emphasize the exception to the rule when it comes to teaching genetics, focusing heavily on rare single-gene and Mendelian traits. By contrast, the vast majority of human traits and diseases are caused by more complicated interactions between genetic and environmental factors. Research indicates that students have a deterministic view of genetics, generalize Mendelian inheritance patterns to all traits, and have unrealistic expectations of genetic technologies. The challenge lies in how to help students analyze complex disease risk with a lack of curriculum materials. Providing open access to both content resources and an engaging storyline can be achieved using a "serious game" model. "Touching Triton" was developed as a serious game in which students are asked to analyze data from a medical record, family history, and genomic report in order to develop an overall lifetime risk estimate of six common, complex diseases. Evaluation of student performance shows significant learning gains in key content areas along with a high level of engagement.

Providing feedback to students as they learn to integrate individual concepts into complex systems is an important way to help them to develop robust understanding, but it is challenging in large, undergraduate classes for instructors to provide feedback that is frequent and directed enough to help individual students. Various scaffolds can be used to help students engage in self-regulated learning and generate internal feedback to improve their learning. This study examined the use of enhanced answer keys with added reflection questions and instruction as scaffolds for engaging undergraduate students in self-regulated learning within an introductory biology course. Study findings show that both the enhanced answer keys and reflection questions helped students to engage in metacognition and develop greater understanding of biological concepts. Further, students who received additional instruction on the use of the scaffolds changed how they used them and, by the end of the semester, were using the scaffolds in significantly different ways and showed significantly higher learning gains than students who did not receive the instruction. These findings provide evidence for the benefit of designing scaffolds within biology courses that will support students in engaging in metacognition and enhancing their understanding of biological concepts.

2018-03-01
This study established whether 12 South African secondary school physics students had incorrect conceptions of basic magnetism and if they had, to what extent they consistently applied such conceptions. Different scenarios in the form of thought experiments were presented in a clinical interview approach. A complex systems perspective underpinned the study and was firstly used to analyze 12 students' conceptions in terms of intuitive fragments of knowledge elements, structured misconceptions, and theory-like system of knowledge elements. Secondly, coherence in each student's ideas expressed across ten themes using thought experiments was analyzed in an effort to determine variations or coherence in responses. Examples of student explanations and sketches are discussed in the paper to illustrate the conceptual structures they applied. Most of the students in this study used a variety of knowledge elements in accord with a complex systems perspective, but three students seemed to prefer a specific perspective. One student's ideas tended to be mainly fragmented, a second exposed a number of structured misconceptions, while another student's reasoning can be described as a theory-like system of knowledge elements. Accordingly, the emphasis of physics education research should no longer be on the compilation of a list of misconceptions that have to be remedied or replaced, but on the conceptual connections, students make and their associative reasoning patterns (i.e., knowledge systems revealed). It remains for the teacher to use the complex systems perspective as a framework to facilitate students' conceptual development and understanding, proceeding on their existing knowledge systems.

Biochemistry students' ideas about how an enzyme interacts with a substrate.
Linenberger, Kimberly J; Bretz, Stacey Lowery
2015-01-01
Enzyme-substrate interactions are a fundamental concept of biochemistry that is built upon throughout multiple biochemistry courses. Central to understanding enzyme-substrate interactions is specific knowledge of exactly how an enzyme and substrate interact. Within this narrower topic, students must understand the various binding sites on an enzyme and be able to reason from simplistic lock and key or induced fit models to the more complex energetics model of transition state theory. Learning to understand these many facets of enzyme-substrate interactions and reasoning from multiple models present challenges where students incorrectly make connections between concepts or make no connection at all. This study investigated biochemistry students' understanding of enzyme-substrate interactions through the use of clinical interviews and a national administration (N = 707) of the Enzyme-Substrate Interactions Concept Inventory. Findings include misconceptions regarding the nature of enzyme-substrate interactions, naïve ideas about the active site, a lack of energetically driven interactions, and an incomplete understanding of the specificity pocket. © 2015 by the International Union of Biochemistry and Molecular Biology.

View change about socio-scientific issues has been well studied in the literature, but the change in the complexity of those views has not. In the current study, the change in the complexity of views about a specific scientific topic (i.e. genetically modified organisms; GMOs) and use of evidence in explaining those views was examined in relation to individual factors and type of text (informational, persuasive, or narrative). Undergraduate students completed measures of their prior views about GMOs their epistemic beliefs about the nature of science, and activities related to food consumption. Participants then read either an informational, persuasive, or narrative passage about GMOs and again answered a question related to their views about GMOs. Participants who read the persuasive passage decreased in the complexity of their views, while those who read the narrative and expository passage increased in the complexity of their views. Additionally, while cultural activities related to the complexity of individuals' views during the pretest, these significant differences were not evident at posttest after the text intervention. These findings can be used to help scientists and teachers better understand how to communicate information critical to understanding complex science and environmental issues to the public and their students.
Ethical reasoning through simulation: a phenomenological analysis of student experience.
Lewis, Gareth; McCullough, Melissa; Maxwell, Alexander P; Gormley, Gerard J
2016-01-01
Medical students transitioning into professional practice feel underprepared to deal with the emotional complexities of real-life ethical situations. Simulation-based learning (SBL) may provide a safe environment for students to probe the boundaries of ethical encounters. Published studies of ethics simulation have not generated sufficiently deep accounts of student experience to inform pedagogy. The aim of this study was to understand students' lived experiences as they engaged with the emotional challenges of managing clinical ethical dilemmas within a SBL environment. This qualitative study was underpinned by an interpretivist epistemology. Eight senior medical students participated in an interprofessional ward-based SBL activity incorporating a series of ethically challenging encounters. Each student wore digital video glasses to capture point-of-view (PoV) film footage. Students were interviewed immediately after the simulation and the PoV footage played back to them. Interviews were transcribed verbatim. An interpretative phenomenological approach, using an established template analysis approach, was used to iteratively analyse the data. Four main themes emerged from the analysis: (1) 'Authentic on all levels?', (2)'Letting the emotions flow', (3) 'Ethical alarm bells' and (4) 'Voices of children and ghosts'. Students recognised many explicit ethical dilemmas during the SBL activity but had difficulty navigating more subtle ethical and professional boundaries. In emotionally complex situations, instances of moral compromise were observed (such as telling an untruth). Some participants felt unable to raise concerns or challenge unethical behaviour within the scenarios due to prior negative undergraduate experiences. This study provided deep insights into medical students' immersive and embodied experiences of ethical reasoning during an authentic SBL activity. By layering on the human dimensions of ethical decision-making, students can understand their personal responses to emotion, complexity and interprofessional working. This could assist them in framing and observing appropriate ethical and professional boundaries and help smooth the transition into clinical practice.

Three-dimensional (3-D) representation is thought to improve understanding of complex spatial interactions and is being used more frequently in diagnostic and therapeutic procedures. It has been suggested that males benefit more than females from 3-D presentations. There have been few randomised trials to confirm these issues. We carried out a randomised trial, based on the identification of complex surgical liver anatomy, to evaluate whether 3-D presentation has a beneficial impact and if gender differences were evident. A computer-based teaching module (TM) was developed to test whether two-dimensional (2-D) computed tomography (CT) images or 3-D presentations result in better understanding of liver anatomy. Following a PowerPoint lecture, students were randomly selected to participate in computer-based testing which used either 2-D images presented as consecutive transversal slices, or one of two 3-D variations. In one of these the vessel tree of portal and hepatic veins was shown in one colour (3-D) and in the other the two vessel systems were coloured differently (3-Dc). Participants were asked to answer 11 medical questions concerning surgical anatomy and four questions on their subjective assessment of the TM. Of the 160 Year 4 and 5 medical students (56.8% female) who participated in this prospective randomised trial, students exposed to 3-D presentation performed significantly better than those exposed to 2-D images (p < 0.001). Comparison of the number of correct answers revealed no significant differences between the 3-D and 3-Dc modalities p > 0.1). Male students gave significantly more correct answers in the 3-D and 3-Dc modalities than female students (p < 0.03). The gender difference observed in both 3-D modalities was not evident in the 2-D group (p = 0.21). This study showed that 3-D imaging significantly improved the identification of complex surgical liver anatomy. Male students benefited significantly more than female students from 3-D presentations. Use of colour in 3-D presentation did not improve student performance.
Diagnosing Students' Understanding of the Nature of Models

Gogolin, Sarah; Krüger, Dirk
2017-10-01
Students' understanding of models in science has been subject to a number of investigations. The instruments the researchers used are suitable for educational research but, due to their complexity, cannot be employed directly by teachers. This article presents forced choice (FC) tasks, which, assembled as a diagnostic instrument, are supposed to measure students' understanding of the nature of models efficiently, while being sensitive enough to detect differences between individuals. In order to evaluate if the diagnostic instrument is suitable for its intended use, we propose an approach that complies with the demand to integrate students' responses to the tasks into the validation process. Evidence for validity was gathered based on relations to other variables and on students' response processes. Students' understanding of the nature of models was assessed using three methods: FC tasks, open-ended tasks and interviews ( N = 448). Furthermore, concurrent think-aloud protocols ( N = 30) were performed. The results suggest that the method and the age of the students have an effect on their understanding of the nature of models. A good understanding of the FC tasks as well as a convergence in the findings across the three methods was documented for grades eleven and twelve. This indicates that teachers can use the diagnostic instrument for an efficient and, at the same time, valid diagnosis for this group. Finally, the findings of this article may provide a possible explanation for alternative findings from previous studies as a result of specific methods that were used.
Visualizing protein interactions and dynamics: evolving a visual language for molecular animation.
Jenkinson, Jodie; McGill, Gaël
2012-01-01
Undergraduate biology education provides students with a number of learning challenges. Subject areas that are particularly difficult to understand include protein conformational change and stability, diffusion and random molecular motion, and molecular crowding. In this study, we examined the relative effectiveness of three-dimensional visualization techniques for learning about protein conformation and molecular motion in association with a ligand-receptor binding event. Increasingly complex versions of the same binding event were depicted in each of four animated treatments. Students (n = 131) were recruited from the undergraduate biology program at University of Toronto, Mississauga. Visualization media were developed in the Center for Molecular and Cellular Dynamics at Harvard Medical School. Stem cell factor ligand and cKit receptor tyrosine kinase were used as a classical example of a ligand-induced receptor dimerization and activation event. Each group completed a pretest, viewed one of four variants of the animation, and completed a posttest and, at 2 wk following the assessment, a delayed posttest. Overall, the most complex animation was the most effective at fostering students' understanding of the events depicted. These results suggest that, in select learning contexts, increasingly complex representations may be more desirable for conveying the dynamic nature of cell binding events.
Evaluation of a computer-based approach to teaching acid/base physiology.
Rawson, Richard E; Quinlan, Kathleen M
2002-12-01
Because acid/base physiology is a difficult subject for most medical and veterinary students, the first author designed a software program, Acid/Base Primer, that would help students with this topic. The Acid/Base Primer was designed and evaluated within a conceptual framework of basic educational principles. Seventy-five first-year veterinary students (of 81; 93% response rate) participated in this study. Students took both a pre- and posttest of content understanding. After completing the Acid/Base Primer in pairs, each student filled out a survey evaluating the features of the program and describing his/her use and experience of it. Four pairs of students participated in interviews that elaborated on the surveys. Scores improved from 53 +/- 2% on the pretest to 74 +/- 1% on an immediate posttest. On surveys and in interviews, students reported that the program helped them construct their own understanding of acid/base physiology and prompted discussions in pairs of students when individual understandings differed. The case-based format provided anchors and a high degree of relevance. Repetition of concepts helped students develop a more complex network of understanding. Questions in the program served to scaffold the learning process by providing direction, accentuating the relevant features of the cases, and provoking discussion. Guidelines for software development were generated on the basis of the findings and relevant educational literature.

Knowledge dimensions in hypothesis test problems
NASA Astrophysics Data System (ADS)
Krishnan, Saras; Idris, Noraini
2012-05-01
The reformation in statistics education over the past two decades has predominantly shifted the focus of statistical teaching and learning from procedural understanding to conceptual understanding. The emphasis of procedural understanding is on the formulas and calculation procedures. Meanwhile, conceptual understanding emphasizes students knowing why they are using a particular formula or executing a specific procedure. In addition, the Revised Bloom's Taxonomy offers a twodimensional framework to describe learning objectives comprising of the six revised cognition levels of original Bloom's taxonomy and four knowledge dimensions. Depending on the level of complexities, the four knowledge dimensions essentially distinguish basic understanding from the more connected understanding. This study identifiesthe factual, procedural and conceptual knowledgedimensions in hypothesis test problems. Hypothesis test being an important tool in making inferences about a population from sample informationis taught in many introductory statistics courses. However, researchers find that students in these courses still have difficulty in understanding the underlying concepts of hypothesis test. Past studies also show that even though students can perform the hypothesis testing procedure, they may not understand the rationale of executing these steps or know how to apply them in novel contexts. Besides knowing the procedural steps in conducting a hypothesis test, students must have fundamental statistical knowledge and deep understanding of the underlying inferential concepts such as sampling distribution and central limit theorem. By identifying the knowledge dimensions of hypothesis test problems in this study, suitable instructional and assessment strategies can be developed in future to enhance students' learning of hypothesis test as a valuable inferential tool.
The optic pathway: the development of an eLearning animation.
Cooper, Claire; Erolin, Caroline
2018-04-01
The optic pathway is responsible for sending visual information from the eyes to the brain via electrical impulses. It is essential that a sound understanding of this pathway is established in order to determine an accurate diagnosis concerning visual field defects. Although easy for trained neurologists to understand, it is an area which medical students repeatedly struggle to visualise. It is proposed that audio-visual teaching resources can improve students understanding of complex areas of importance. This article describes the development and evaluation of a short animation created for use in the undergraduate neurology curriculum at the University of Dundee School of Medicine.

Nordic networking of different kinds has a long tradition aiming to increase collaboration and understanding between citizens in different countries. Cultural competence in relation to health care and nursing is important for clinical nurses and is a central issue in nurse education. To gain an understanding of what nurse students experienced and learned during an intensive course in diabetes together with students and nurse educators from Denmark, Finland, Iceland, Norway, Sweden and the Faroe Islands. In 2012, an intensive course within the Nordic network, Nordkvist, was conducted in Faroe Islands with the theme "Nursing - to live a good life with diabetes". To answer the objective of the study, 26 students conducted written reflections based on two questions. The data was analyzed using qualitative content analysis. Through meetings with nurse students and educators from the Nordic countries the intensive course strengthened the students' identification with the nursing profession. The students gained new perspectives on diabetes, such as how complex it can be to live with a chronic illness. Because of the difficulties in understanding one another and because of different mother tongues, the students gained a better understanding of patients' vulnerability in relation to hospital jargon and how it felt to be in an unfamiliar place. The intensive course increased the students' personal and professional growth, cross-cultural competence, and their identification with nursing. Students' understanding of health care in the Nordic countries improved as similarities and differences were recognized. Copyright © 2015 Elsevier Ltd. All rights reserved.

2012-06-01
The purpose of this study was to investigate the perspectives of occupational therapy students who have engaged in international, cross-cultural learning and service experiences. This study utilized a qualitative, phenomenological design. Nine semi-structured interviews were conducted with students who engaged in international learning opportunities. The interviews were coded and analyzed using a constant comparative analysis approach. Three central themes emerged from the data analysis. Connectedness is the process of forming relationships with others while engaging in cross-cultural experiences. Students formed relationships with faculty, other students, and people within the community. Cultural awareness is the recognition and understanding of a different culture and responding to those differences. Students attempted to understand the new culture in comparison to their own lived experiences. Complexity portrays cross-cultural opportunities as dynamic, multi-faceted and intricate. This was demonstrated as the students raised additional questions about the conflict between their own culture and the new culture they entered. Students also identified limited orientation, support and structure with such experiences and the conflicting roles between volunteer, student, and team member. The ability to connect with others when building relationships in diverse cultural contexts held meaning for the students; however, the students also expressed conflict in trying to make sense of the new culture as it often challenged personal beliefs and constructs. The complexity and challenges of engaging in these opportunities needs to be recognized and further explored to assess how curricula and faculty best supports culturally responsive care. © 2011 The Authors Australian Occupational Therapy Journal © 2011 Occupational Therapy Australia.

Background: This exploratory study is part of a larger-scale research project aimed at building theoretical and practical knowledge of complex systems in students and teachers with the goal of improving high school biology learning through professional development and a classroom intervention. Purpose: We propose a model of adaptive expertise to better understand teachers' classroom practices as they attempt to navigate myriad variables in the implementation of biology units that include working with computer simulations, and learning about and teaching through complex systems ideas. Sample: Research participants were three high school biology teachers, two females and one male, ranging in teaching experience from six to 16 years. Their teaching contexts also ranged in student achievement from 14-47% advanced science proficiency. Design and methods: We used a holistic multiple case study methodology and collected data during the 2011-2012 school year. Data sources include classroom observations, teacher and student surveys, and interviews. Data analyses and trustworthiness measures were conducted through qualitative mining of data sources and triangulation of findings. Results: We illustrate the characteristics of adaptive expertise of more or less successful teaching and learning when implementing complex systems curricula. We also demonstrate differences between case study teachers in terms of particular variables associated with adaptive expertise. Conclusions: This research contributes to scholarship on practices and professional development needed to better support teachers to teach through a complex systems pedagogical and curricular approach.

It is quite difficult to teach complex topics like the physiology of vestibular apparatus to undergraduate students. Understanding the orientation and mode of stimulation of receptors in vestibular apparatus is also quite challenging for the students. As faculty we attempt to use innovative methods to teach physiology and enhance student learning. This article describes a simple and innovative method (student-involved demonstration approach, or SID) to teach the physiology of the vestibular apparatus to the undergraduate medical students. The current study describes a protocol where students engage in role-play sessions in the middle of the regular didactic lectures. Effectiveness of the sessions was later evaluated by using a questionnaire and by comparing the pre-SID and post-SID test results of the students. The posttest score of the students was significantly higher than the pretest score, and this indicates the usefulness of SID sessions on enhancing the student learning in the class. Students also found this method very interesting and useful in better understanding the physiology of the vestibular apparatus.

Americans, in general, do not behave in environmentally sustainable ways. We drive cars and fly in planes that emit planet-warming carbon. We purchase food in nearly indestructible packaging that is not recycled or repurposed. We do not consider the environmental impact of the "stuff" stuffed into our grocery and department stores, most of which is made of materials that had to be dug out of the ground, leaving rivers and skies full of pollution in its place. Citizens have a responsibility to understand complex global and local environmental problems. A person's ability to think about the way that an environmental problem they are tasked with understanding changes over time and space can better prepare them to make sustainable decisions in the face of this complexity. Spatial thinking serves the learner's ability to understand the impact of environmental actions and should be given a consistent place in environmental education. Teaching practices and pedagogies that focus on spatial thinking are necessary to learners' success. In order to know if these strategies are successful, educators need an assessment tool that targets the spatial thinking skills necessary to understanding environmental problems. This dissertation project used a models and modeling theoretical framework to develop and test an assessment of students' spatial thinking abilities related to the environmental problem of enhanced greenhouse effect. This assessment was developed from a review of existing spatial thinking literature, research on existing assessments of spatial thinking abilities, and existing assessment of enhanced greenhouse effect. In addition, I interviewed and surveyed experts in science, math, and environmental education to elicit their perspectives on the spatial thinking skills necessary for learners to understand enhanced greenhouse effect. All of this information was synthesized into 14 Central Concepts of spatial thinking for enhanced greenhouse effect. The assessment was developed for students to express their mental models related to these 14 Central Concepts. The assessment was reviewed and tested by experts related to the project's content, as well as students from the target population for assessment delivery. It was revised based on feedback and data collect from these groups. Here I describe my findings, that students are more proficient at modeling simple spatial relationships, one at a time, than modeling more complex relationships; that students understand human-scale spatial relationships related to enhanced greenhouse effect better than very small or very large ones; and that students can associate and correlate spatially distributed features and phenomena to describe enhanced greenhouse effect. Finally, I describe the ways in which student and expert feedback has informed not only revisions of this assessment specifically, but also to the assessment development process, for better assessment design, when spatial thinking assessments related to other environmental problems are developed in the future.

Exposing earth system science (ESS) concepts into introductory geoscience courses may present new and unique cognitive learning issues for students including understanding the role of positive and negative feedbacks in system responses to perturbations, spatial heterogeneity, and temporal dynamics, especially when systems exhibit complex behavior. Implicit learning goals of typical introductory undergraduate geoscience courses are more focused on building skill-sets and didactic knowledge in learners than developing a deeper understanding of the dynamics and processes of complex earth systems through authentic inquiry. Didactic teaching coupled with summative assessment of factual knowledge tends to limit student¡¦s understanding of the nature of science, their belief in the relevancy of science to their lives, and encourages memorization and regurgitation; this is especially true among the non-science majors who compose the majority of students in introductory courses within the large university setting. Students organize scientific knowledge and reason about earth systems by manipulating internally constructed mental models. This pilot study focuses on characterizing the impact of inquiry-based learning with multiple representations to foster critical thinking and mental model development about authentic environmental issues of coastal systems in an introductory geoscience course. The research was conducted in nine introductory physical geology laboratory sections (N ˜ 150) at Texas A&M University as part of research connected with the Information Technology in Science (ITS) Center. Participants were randomly placed into experimental and control groups. Experimental groups were exposed to multiple representations including both web-based learning materials (i.e. technology-supported visualizations and analysis of multiple datasets) and physical models, whereas control groups were provided with the traditional ¡workbook style¡" laboratory assignments. Assessment of pre- and post-test results was performed to provide indications of content knowledge and mental model expression improvements between groups. A rubric was used as the assessment instrument to evaluate student products (Cronbach alpha: 0.84 ¡V 0.98). Characterization of student performance based on a Student¡¦s t-test indicates that significant differences (p < 0.05) in pre-post achievement occurred primarily within the experimental group; this illustrates that the use of multiple representations had an impact on student learning of ESS concepts, particularly in regard to mental model constructions. Analysis of variance also suggests that student mental model constructions were significantly different (p < 0.10) between test groups. Factor analysis extracted three principle components (eigenvalue > 1) which show similar clustering of variables that influence cognition, indicating that the cognitive processes driving student understanding of geoscience do not vary among student test groups. Categories of cognition include critical thinking skills (percent variance = 22.16%), understanding of the nature of science (percent variance = 25.16%), and ability to interpret results (percent variance = 28.89%). Lower numbers of students completed all of the required assignments of this research than expected (65.3%), restricting the quality of the results and therefore the ability to make more significant interpretations; this was likely due to the non-supportive learning environment in which the research was implemented.

One aim of science education is to develop scientific literacy for decision-making in daily life. Socio-scientific issues (SSI) and structured decision-making frameworks can help students reach these objectives. This research uses value belief norm (VBN) theory and construal level theory (CLT) to explore students' use of personal values in their decision-making processes and the relationship between abstract and concrete problematization and their decision-making. Using mixed methods, we conclude that the level of abstraction with which students problematise a prairie dog agricultural production and ecosystem preservation issue has a significant relationship to the values students used in the decision-making process. However, neither abstraction of the problem statement nor students' surveyed value orientations were significantly related to students' final decisions. These results may help inform teachers' understanding of students and their use of a structured-decision making tool in a classroom, and aid researchers in understanding if these tools help students remain objective in their analyses of complex SSIs.

The purpose of this study was to compare two pedagogical methods, active learning and passive instruction, to determine which is more useful in helping students to achieve the learning outcomes in a one-hour research skills instructional session. Two groups of high school students attended an instructional session to learn about consumer health resources and strategies to enhance their searching skills. The first group received passive instruction, and the second engaged in active learning. We assessed both groups' learning using 2 methods with differing complexity. A total of 59 students attended the instructional sessions (passive instruction, n=28; active learning, n=31). We found that the active learning group scored more favorably in four assessment categories. Active learning may help students engage with and develop a meaningful understanding of several resources in a single session. Moreover, when using a complex teaching strategy, librarians should be mindful to gauge learning using an equally complex assessment method.

Effective feedback strategies for teaching in pediatric and adolescent gynecology.
Kaul, Paritosh; Gong, Jennifer; Guiton, Gretchen
2014-08-01
The clinical setting of pediatric and adolescent gynecology poses complex tasks for the physician with its numerous procedures and the communication demands of interacting with an adolescent and/or guardian. Needless to say, teaching within this setting is highly demanding. Regardless of the level of learner or the professional role (e.g., nurse, medical student, resident, physician assistant) represented, clinical teaching requires that the instructor provide feedback in ways that benefit the student. Recent research on feedback suggests a more complex understanding of feedback than in the past. This article highlights key research and its implication for effective feedback by presenting a three part framework; know your learner, understand what is to be learned, and plan for improvement.

Visintainer, Tammie; Linn, Marcia
2015-04-01
Developing solutions for complex issues such as global climate change requires an understanding of the mechanisms involved. This study reports on the impact of a technology-enhanced unit designed to improve understanding of global climate change, its mechanisms, and their relationship to everyday energy use. Global Climate Change, implemented in the Web-based Inquiry Science Environment (WISE), engages sixth-grade students in conducting virtual investigations using NetLogo models to foster an understanding of core mechanisms including the greenhouse effect. Students then test how the greenhouse effect is enhanced by everyday energy use. This study draws on three data sources: (1) pre- and post-unit interviews, (2) analysis of embedded assessments following virtual investigations, and (3) contrasting cases of two students (normative vs. non-normative understanding of the greenhouse effect). Results show the value of using virtual investigations for teaching the mechanisms associated with global climate change. Interviews document that students hold a wide range of ideas about the mechanisms driving global climate change. Investigations with models help students use evidence-based reasoning to distinguish their ideas. Results show that understanding the greenhouse effect offers a foundation for building connections between everyday energy use and increases in global temperature. An impediment to establishing coherent understanding was the persistence of an alternative conception about ozone as an explanation for climate change. These findings illustrate the need for regular revision of curriculum based on classroom trials. We discuss key design features of models and instructional revisions that can transform the teaching and learning of global climate change.
Concept Maps for Improved Science Reasoning and Writing: Complexity Isn't Everything.
Dowd, Jason E; Duncan, Tanya; Reynolds, Julie A
2015-01-01
A pervasive notion in the literature is that complex concept maps reflect greater knowledge and/or more expert-like thinking than less complex concept maps. We show that concept maps used to structure scientific writing and clarify scientific reasoning do not adhere to this notion. In an undergraduate course for thesis writers, students use concept maps instead of traditional outlines to define the boundaries and scope of their research and to construct an argument for the significance of their research. Students generate maps at the beginning of the semester, revise after peer review, and revise once more at the end of the semester. Although some students revised their maps to make them more complex, a significant proportion of students simplified their maps. We found no correlation between increased complexity and improved scientific reasoning and writing skills, suggesting that sometimes students simplify their understanding as they develop more expert-like thinking. These results suggest that concept maps, when used as an intervention, can meet the varying needs of a diverse population of student writers. © 2015 J. E. Dowd et al.

A Study Of Undergraduate Students' Alternative Conceptions Of Earth's Interior Using Drawing Tasks
NASA Astrophysics Data System (ADS)
McAllister, Meredith L.
2014-12-01
Learning fundamental geoscience topics such as plate tectonics, earthquakes, and volcanoes requires students to develop a deep understanding of the conceptual models geologists use when describing the structure and dynamics of Earth's interior. Despite the importance of these mental models underlying much of the undergraduate geoscience curriculum, surprisingly little research related to this complex idea exists in the discipline-based science education research literature. To better understand non-science-majoring undergraduates' conceptual models of Earth's interior, student-generated drawings and interviews were used to probe student understanding of the Earth. Ninety-two semi-structured interviews were conducted with non-science-major college students at the beginning of an entry-level geology course at a large Midwestern university. Students were asked to draw a picture of Earth's interior and provide think-aloud explanations of their drawings. The results reveal that students hold a wide range of alternative conceptions about Earth, with only a small fraction having scientifically accurate ideas. Students' understandings ranged from conceptualizing Earth's interior as consisting of horizontal layers of rock and dirt, to more sophisticated views with Earth's interior being composed of concentric layers with unique physical and chemical characteristics. Processes occurring within Earth, such as "convection," were rarely mentioned or explained. These results provide a first-steps basis from which to further explore college students' thinking and contribute to the growing body of knowledge on earth science teaching and geoscience education research.

Exploring Nursing Students' Experiences of Learning Using Phenomenography: A Literature Review.
Barry, Sinead; Ward, Louise; Walter, Ruby
2017-10-01
The purpose of this extensive international and national literature review was to explore how phenomenography identifies nursing students' experiences of learning within preregistration (or prelicensure) nursing education. Data were collected utilizing a comprehensive search of electronic databases. Full text, peer-reviewed, and scholarly articles published in English using the search terms phenomengraph*, nurs*, student, education, and learning were reviewed. Two discreet themes emerged exploring students' experiences of learning within preregistration nursing education: (a) Phenomenography was a beneficial method to expose variation in students' understandings of a challenging concept or topic and (b) phenomenography was beneficial to evaluate teaching methods in attempt to improve student learning of challenging and complex concepts. On the basis of these findings, future research utilizing phenomenography within nursing education has potential to uncover variation in students' understandings of mental health, with future consideration of implications to nursing curriculum design and development.

How Students Combine Resources to Make Conceptual Breakthroughs

Richards, A. J.; Jones, Darrick C.; Etkina, Eugenia
2018-04-01
We use the framework of cognitive resources to investigate how students construct understanding of a complex physics topic, namely, a photovoltaic cell. By observing students as they learn about how a solar cell functions, we identified over 60 distinct resources that learners may activate while thinking about photovoltaic cells. We classify these resources into three main types: phenomenological primitives, conceptual resources, and epistemological resources. Furthermore, we found a pattern that suggests that when students make conceptual breakthroughs they may be more likely to activate combinations of resources of different types in concert, especially if a resource from each of the three categories is used. This pattern suggests that physics instructors should encourage students to activate multiple types of prior knowledge during the learning process. This can result from instructors deliberately and explicitly connecting new knowledge to students' prior experience both in and outside the formal physics classroom, as well as allowing students to reflect metacognitively on how the new knowledge fits into their existing understanding of the natural world.

One of the challenges related to hazard communication concerns the public perception and understanding of scientific uncertainties, and of its implications in terms of hazard assessment and mitigation. Often science is perceived as an effective dispenser of resolving answers to the main issues posed by the complexities of life and nature. In this perspective, uncertainty is seen as a pernicious lack of knowledge that hinders our ability to face complex problems. From a scientific perspective, however, the definition of uncertainty is the only valuable tool we have to handle errors affecting our data and propagating through the increasingly complex models we develop to describe reality. Through uncertainty, scientists acknowledge the great variability that characterises natural systems and account for it in their assessment of possible scenarios. From this point of view, uncertainty is not ignorance, but it rather provides a great deal of information that is needed to inform decision making. To find effective ways to bridge the gap between these different meaning of uncertainty, we asked high-school students for assistance. With their help, we gathered definitions of the term 'uncertainty' interviewing different categories of peoples, including schoolmates and professors, neighbours, families and friends. These definitions will be compared with those provided by scientists, to find differences and similarity. To understand the role of uncertainty on judgment, a hands-on experiment is performed where students will have to estimate the exact time of explosion of party poppers subjected to a variable degree of pull. At the end of the project, the students will express their own understanding of uncertainty in a video, which will be made available for sharing. Materials collected during all the activities will contribute to our understanding of how uncertainty is portrayed and can be better expressed to improve our hazard communication.

Three-dimensional (3D) information plays an important part in medical and veterinary education. Appreciating complex 3D spatial relationships requires a strong foundational understanding of anatomy and mental 3D visualization skills. Novel learning resources have been introduced to anatomy training to achieve this. Objective evaluation of their comparative efficacies remains scarce in the literature. This study developed and evaluated the use of a physical model in demonstrating the complex spatial relationships of the equine foot. It was hypothesized that the newly developed physical model would be more effective for students to learn magnetic resonance imaging (MRI) anatomy of the foot than textbooks or computer-based 3D models. Third year veterinary medicine students were randomly assigned to one of three teaching aid groups (physical model; textbooks; 3D computer model). The comparative efficacies of the three teaching aids were assessed through students' abilities to identify anatomical structures on MR images. Overall mean MRI assessment scores were significantly higher in students utilizing the physical model (86.39%) compared with students using textbooks (62.61%) and the 3D computer model (63.68%) (P < 0.001), with no significant difference between the textbook and 3D computer model groups (P = 0.685). Student feedback was also more positive in the physical model group compared with both the textbook and 3D computer model groups. Our results suggest that physical models may hold a significant advantage over alternative learning resources in enhancing visuospatial and 3D understanding of complex anatomical architecture, and that 3D computer models have significant limitations with regards to 3D learning. © 2013 American Association of Anatomists.
Life in unexpected places: Employing visual thinking strategies in global health training.

The desire to make meaning out of images, metaphor, and other representations indicates higher-order cognitive skills that can be difficult to teach, especially in the complex and unfamiliar environments like those encountered in many global health experiences. Because reflecting on art can help develop medical students' imaginative and interpretive skills, we used visual thinking strategies (VTS) during an immersive 4-week global health elective for medical students to help them construct new understanding of the social determinants of health in a low-resource setting. We were aware of no previous formal efforts to use art in global health training. We assembled a group of eight medical students in front of a street mural in Kathmandu and used VTS methods to interpret the scene with respect to the social determinants of health. We recorded and transcribed the conversation and conducted a thematic analysis of student responses. Students shared observations about the mural in a supportive, nonjudgmental fashion. Two main themes emerged from their observations: those of human-environment interactions (specifically community dynamics, subsistence land use, resources, and health) and entrapment/control, particularly relating to expectations of, and demands on, women in traditional farming communities. They used the images as well as their experience in Nepali communities to consolidate complex community health concepts. VTS helped students articulate their deepening understanding of the social determinants of health in Nepal, suggesting that reflection on visual art can help learners apply, analyze, and evaluate complex concepts in global health. We demonstrate the relevance of drawing upon many aspects of cultural learning, regarding art as a kind of text that holds valuable information. These findings may help provide innovative opportunities for teaching and evaluating global health training in the future.
Students' development of astronomy concepts across time

The National Science Education Standards (NRC, 1996) recommend that students understand the apparent patterns of motion of the sun, moon and stars visible by the end of early elementary school. However, little information exists on students' knowledge of apparent celestial motion or instruction in this area. The goals of this dissertation were to describe children's knowledge of apparent celestial motion across elementary and middle school, explore early elementary students' ability to learn these topics through planetarium instruction, and begin the development of a learning progression for these concepts, First, third, and eighth grade students (N=60) were interviewed using a planetarium-like setting that allowed the students to demonstrate their ideas both verbally and with their own motions on an artificial sky. Analysis of these interviews suggests that students are not making the types of observations of the sky necessary to learn apparent celestial motion and any instruction they may have received has not helped them reach an accurate understanding of most topics. Most students at each grade level could not accurately describe the patterns of motion. Though the older students were more accurate in most of their descriptions than the younger students, in several areas the eighth grade students showed no improvement over the third grade students. The use of kinesthetic learning techniques in a planetarium program was also explored as a method to improve understanding of celestial motion. Pre- and post-interviews were conducted with participants from seven classes of first and second grade students (N=63). Students showed significant improvement in all areas of apparent celestial motion covered by the planetarium program and surpassed the middle school students' understanding of these concepts in most areas. This suggests that students in early elementary school are capable of learning the accurate description of apparent celestial motion. The results demonstrate the value of both kinesthetic learning techniques and the rich visual environment of the planetarium for improved understanding of celestial motion. Based on the results of these studies, I developed a learning progression describing how children may progress through successively more complex ways of understanding apparent celestial motion across elementary grades.

Interprofessional collaborative practice is increasingly recognized as an essential model in health care. This study lends preliminary support to the notion that medical students (including residents) and social work students develop a broader understanding of one another's roles and contributions to enhancing community-dwelling geriatric patients' health, and develop a more thorough understanding of the inherent complexities and unique aspects of geriatric health care. Wilcoxon Signed Rank Tests of participants' scores on the Index of Interdisciplinary Collaboration (IIC) indicated the training made significant changes to the students' perception of interprofessional collaboration. Qualitative analysis of participants' statements illustrated (1) benefits of the IPE experience, including complementary roles in holistic interventions; and (2) challenges to collaboration. The findings suggest that interprofessional educational experiences have a positive impact upon students' learning and strategies for enhanced care of geriatric patients.
Helping secondary school students develop a conceptual understanding of refraction

Ashmann, Scott; Anderson, Charles W.; Boeckman, Heather
2016-07-01
Using real-world examples, ray diagrams, and a cognitive apprenticeship cycle, this paper focuses on developing students’ conceptual (not mathematical) understanding of refraction. Refraction can be a difficult concept for students to comprehend if they do not have well-designed opportunities to practice explaining situations where reflection and refraction occur. The use of ray diagrams can be useful in (a) the teacher modelling a correct explanation to a situation where refraction occurs and (b) for students to create as they practice other examples. This paper includes eight examples of increasing complexity that use a cognitive apprenticeship cycle approach to scaffold student learning. The first examples (rock fish, floating penny) are shown and a solution is modeled using a ray diagram. Three more examples (bent pencil, dropping an item in water, sunrise/sunset) are presented for students to practice, with each becoming more sophisticated. Three assessment exercises are then provided (two dots, three coins, broken tube).

Experiences Teaching Stoichiometry to Students in Grades 10 and 11
NASA Astrophysics Data System (ADS)
Bridges, Cynthia Denise
Many students have problems learning stoichiometry, a complex mathematical chemistry concept used to determine how much product will be produced or formed from a given quantity of reactants. The problem addressed in this study was teachers' lack of understanding of how to teach stoichiometry in a Midwestern urban school district. The conceptual framework of the study was based upon constructivist theory. A qualitative narrative approach was used to obtain the perceptions of 5 high school chemistry instructors related to their experiences, successful or unsuccessful, in teaching stoichiometry to students in Grades 10 and 11. Data were gathered through face-to-face interviews, which were analyzed via an inductive approach to reveal 6 themes: a difficult subject to teach, presentation of stoichiometry, relevancy, students' reactions, barriers, and gender differences. Findings suggested the need for teachers to be knowledgeable, creative, and resourceful in their subject areas to help their students to learn stoichiometry. Findings also revealed the need for teachers to adapt their instructional strategies and modes of delivery to reflect their students' individual learning styles. Understanding how the participating teachers explained stoichiometry to their students might help other chemistry teachers to examine and adapt their own instructional styles and delivery methods of the concept. This understanding might, in term, help to improve student achievement in stoichiometry in particular and chemistry in general.
Visualizing Protein Interactions and Dynamics: Evolving a Visual Language for Molecular Animation
Jenkinson, Jodie; McGill, Gaël
2012-01-01
Undergraduate biology education provides students with a number of learning challenges. Subject areas that are particularly difficult to understand include protein conformational change and stability, diffusion and random molecular motion, and molecular crowding. In this study, we examined the relative effectiveness of three-dimensional visualization techniques for learning about protein conformation and molecular motion in association with a ligand–receptor binding event. Increasingly complex versions of the same binding event were depicted in each of four animated treatments. Students (n = 131) were recruited from the undergraduate biology program at University of Toronto, Mississauga. Visualization media were developed in the Center for Molecular and Cellular Dynamics at Harvard Medical School. Stem cell factor ligand and cKit receptor tyrosine kinase were used as a classical example of a ligand-induced receptor dimerization and activation event. Each group completed a pretest, viewed one of four variants of the animation, and completed a posttest and, at 2 wk following the assessment, a delayed posttest. Overall, the most complex animation was the most effective at fostering students' understanding of the events depicted. These results suggest that, in select learning contexts, increasingly complex representations may be more desirable for conveying the dynamic nature of cell binding events. PMID:22383622

Understanding the world through a complex systems lens has recently garnered a great deal of interest in many knowledge disciplines. In the educational arena, interactional studies, through their focus on understanding patterns of system behaviour including the dynamical processes and trajectories of learning, lend support for investigating how a complex systems approach can inform educational research. This study uses previously existing literature and tools for complex systems applications and seeks to extend this research base by exploring learning outcomes of a complex systems framework when applied to curriculum and instruction. It is argued that by applying the evolutionary dynamics of variation, interaction and selection, complexity may be harnessed to achieve growth in both the social and cognitive systems of the classroom. Furthermore, if the goal of education, i.e., the social system under investigation, is to teach for understanding, conceptual knowledge of the kind described in Popper's (1972; 1976) World 3, needs to evolve. Both the study of memetic processes and knowledge building pioneered by Bereiter (cf. Bereiter, 2002) draw on the World 3 notion of ideas existing as conceptual artifacts that can be investigated as products outside of the individual mind providing an educational lens from which to proceed. The curricular topic addressed is the development of an ethical understanding of the scientific and technological issues of genetic engineering. 11 grade 8 students are studied as they proceed through 40 hours of curricular instruction based on the complex systems evolutionary framework. Results demonstrate growth in both complex systems thinking and content knowledge of the topic of genetic engineering. Several memetic processes are hypothesized to have influenced how and why ideas change. Categorized by factors influencing either reflective or non-reflective selection, these processes appear to have exerted differential effects on students' abilities to think and act in complex ways at various points throughout the study. Finally, an analysis of winner and loser memes is offered that is intended to reveal information about the conceptual system---its strengths and deficiencies---that can help educators assess curricular goals and organize and construct additional educational activities.

An investigation of successful and unsuccessful students' problem solving in stoichiometry
NASA Astrophysics Data System (ADS)
Gulacar, Ozcan
In this study, I investigated how successful and unsuccessful students solve stoichiometry problems. I focus on three research questions: (1) To what extent do the difficulties in solving stoichiometry problems stem from poor understanding of pieces (domain-specific knowledge) versus students' inability to link those pieces together (conceptual knowledge)? (2) What are the differences between successful and unsuccessful students in knowledge, ability, and practice? (3) Is there a connection between students' (a) cognitive development levels, (b) formal (proportional) reasoning abilities, (c) working memory capacities, (d) conceptual understanding of particle nature of matter, (e) understanding of the mole concept, and their problem-solving achievement in stoichiometry? In this study, nine successful students and eight unsuccessful students participated. Both successful and unsuccessful students were selected among the students taking a general chemistry course at a mid-western university. The students taking this class were all science, non-chemistry majors. Characteristics of successful and unsuccessful students were determined through tests, audio and videotapes analyses, and subjects' written works. The Berlin Particle Concept Inventory, the Mole Concept Achievement Test, the Test of Logical Thinking, the Digits Backward Test, and the Longeot Test were used to measure students' conceptual understanding of particle nature of matter and mole concept, formal (proportional) reasoning ability, working memory capacity, and cognitive development, respectively. Think-aloud problem-solving protocols were also used to better explore the differences between successful and unsuccessful students' knowledge structures and behaviors during problem solving. Although successful students did not show significantly better performance on doing pieces (domain-specific knowledge) and solving exercises than unsuccessful counterparts did, they appeared to be more successful in linking the pieces (conceptual knowledge) and solving complex problems than the unsuccessful student did. Successful students also appeared to be different in how they approach problems, what strategies they use, and in making fewer algorithmic mistakes when compared to unsuccessful students. Successful students, however, did not seem to be statistically significantly different from the unsuccessful students in terms of quantitatively tested cognitive abilities except formal (proportional) reasoning ability and in the understanding of mole concept.

The research recounted in this paper was designed primarily to attempt to understand the reasons for the low uptake of the natural sciences beyond compulsory education in England. This has caused widespread concern within governmental quarters, university science departments and the scientific community as a whole. This research explored the problem from the position of the students who recently made their choices. The student voices were heard through a series of interviews which highlighted the complexities of the process of post-16 choice. Social theories of pedagogy and identity, such as those of Basil Bernstein, were used in an analysis of the interview texts. Dominant themes used by the students in rationalising their post-16 subject choice related to their past pedagogical experiences, school discourses of differentiation and the students' notions of their future educational and occupational pathways. This study provides no simple solutions but highlights the importance of student voice to our understandings of what influences subject choice at this critical post-16 stage.

A novel multimedia three dimensional (3D) computer animated program, called "Ophthalmic Operation Vienna" has been developed, where surgical videos are accompanied by 3D animated sequences of all surgical steps for five operations. The aim of the study was to assess the effect of 3D animations on the understanding of cataract and glaucoma surgery among medical students. Set in the Medical University of Vienna, Department of Ophthalmology, 172 students were randomised into two groups: a 3D group (n=90), that saw the 3D animations and video sequences, and a control group (n=82), that saw only the surgical videos. The narrated text was identical for both groups. After the presentation, students were questioned and tested using multiple choice questions. Students in the 3D group found the interactive multimedia teaching methods to be a valuable supplement to the conventional surgical videos. The 3D group outperformed the control group not only in topographical understanding by 16% (p<0.0001), but also in theoretical understanding by 7% (p<0.003). Women in the 3D group gained most by 19% over the control group (p<0.0001). The use of 3D animations lead to a better understanding of difficult surgical topics among medical students, especially for female users. Gender related benefits of using multimedia should be further explored.

Traditional learning limits the potential for self-discovery, and the use of data and knowledge to understand Earth system relationships, processes, feedback mechanisms and system coupling. It is extremely difficult for undergraduate students to analyze, synthesize, and integrate quantitative information related to complex systems, as many concepts may not be mathematically tractable or yet to be formalized. Conceptual models have long served as a means for Earth scientists to organize their understanding of Earth's dynamics, and have served as a basis for human analytical reasoning and landscape interpretation. Consequently, we evaluated the use of conceptual modeling, knowledge representation and analytical reasoning to provide undergraduate students with an opportunity to develop and test geocomputational conceptual models based upon their understanding of Earth science concepts. This study describes the use of geospatial technologies and fuzzy cognitive maps to predict desertification across the South-Texas Sandsheet in an upper-level geomorphology course. Students developed conceptual models based on their understanding of aeolian processes from lectures, and then compared and evaluated their modeling results against an expert conceptual model and spatial predictions, and the observed distribution of dune activity in 2010. Students perceived that the analytical reasoning approach was significantly better for understanding desertification compared to traditional lecture, and promoted reflective learning, working with data, teamwork, student interaction, innovation, and creative thinking. Student evaluations support the notion that the adoption of knowledge representation and analytical reasoning in the classroom has the potential to transform undergraduate education by enabling students to formalize and test their conceptual understanding of Earth science. A model for developing and utilizing this geospatial technology approach in Earth science is presented.

Helping scientists and engineers challenge received assumptions about how science, engineering, and society relate is a critical cornerstone for macroethics education. Scientific and engineering research are frequently framed as first steps of a value-free linear model that inexorably leads to societal benefit. Social studies of science and assessments of scientific and engineering research speak to the need for a more critical approach to the noble intentions underlying these assumptions. "Science Outside the Lab" is a program designed to help early-career scientists and engineers understand the complexities of science and engineering policy. Assessment of the program entailed a pre-, post-, and 1 year follow up survey to gauge student perspectives on relationships between science and society, as well as a pre-post concept map exercise to elicit student conceptualizations of science policy. Students leave Science Outside the Lab with greater humility about the role of scientific expertise in science and engineering policy; greater skepticism toward linear notions of scientific advances benefiting society; a deeper, more nuanced understanding of the actors involved in shaping science policy; and a continued appreciation of the contributions of science and engineering to society. The study presents an efficacious program that helps scientists and engineers make inroads into macroethical debates, reframe the ways in which they think about values of science and engineering in society, and more thoughtfully engage with critical mediators of science and society relationships: policy makers and policy processes.

Biological systems pose a challenge both for learners and teachers because they are complex systems mediated by feedback loops; networks of cause-effect relationships; and non-linear, hierarchical, and emergent properties. Teachers and scientists routinely use models to communicate ideas about complex systems. Model-based pedagogies engage students in model construction as a means of practicing higher-order reasoning skills. One such modeling paradigm describes systems in terms of their structures, behaviors, and functions (SBF). The SBF framework is a simple modeling language that has been used to teach about complex biological systems. Here, we used student-generated SBF models to assess students' causal reasoning in the context of a novel biological problem on an exam. We compared students' performance on the modeling problem, their performance on a set of knowledge/comprehension questions, and their performance on a set of scientific reasoning questions. We found that students who performed well on knowledge and understanding questions also constructed more networked, higher quality models. Previous studies have shown that learners' mental maps increase in complexity with increased expertise. We wanted to investigate if biology students with varying levels of training in biology showed a similar pattern when constructing system models. In a pilot study, we administered the same modeling problem to two additional groups of students: 1) an animal physiology course for students pursuing a major in biology (n=37) and 2) an exercise physiology course for non-majors (n=27). We found that there was no significant difference in model organization across the three student populations, but there was a significant difference in the ability to represent function between the three populations. Between the three groups the non-majors had the lowest function scores, the introductory majors had the middle function scores, and the upper division majors had the highest function scores.
A novel technique for teaching the brachial plexus.

The brachial plexus has posed problems for both students and teachers throughout generations of medical education. The anatomy is intricate, and traditional pictorial representations can be difficult to understand and learn. Few innovative teaching methods have been reported. The basic anatomy of the brachial plexus is core knowledge required by medical students to aid clinical examination and diagnosis. A more detailed understanding is necessary for a variety of specialists, including surgeons, anaesthetists and radiologists. Here, we present a novel, cheap and interactive method of teaching the brachial plexus. Using coloured pipe cleaners, teachers and students can construct three-dimensional models using different colours to denote the origin and outflow of each nerve. The three-dimensional nature of the model also allows for a better understanding of certain intricacies of the plexus. Students may use these models as adjuncts for self study, didactic lectures and tutorials. Compared with traditional textbooks and whiteboards, the pipe-cleaner model was preferred by medical students, and provided a higher level of student satisfaction. This was demonstrated and analysed using student feedback forms. Our model could be incorporated into current curricula to provide an effective and enjoyable way of rapidly teaching a difficult concept. Other such novel methods for teaching complex anatomical principles should be encouraged and explored. © Blackwell Publishing Ltd 2011.

Providing feedback to students as they learn to integrate individual concepts into complex systems is an important way to help them to develop robust understanding, but it is challenging in large, undergraduate classes for instructors to provide feedback that is frequent and directed enough to help individual students. Various scaffolds can be used to help students engage in self-regulated learning and generate internal feedback to improve their learning. This study examined the use of enhanced answer keys with added reflection questions and instruction as scaffolds for engaging undergraduate students in self-regulated learning within an introductory biology course. Study findings show that both the enhanced answer keys and reflection questions helped students to engage in metacognition and develop greater understanding of biological concepts. Further, students who received additional instruction on the use of the scaffolds changed how they used them and, by the end of the semester, were using the scaffolds in significantly different ways and showed significantly higher learning gains than students who did not receive the instruction. These findings provide evidence for the benefit of designing scaffolds within biology courses that will support students in engaging in metacognition and enhancing their understanding of biological concepts. © 2017 J.

There is growing interest in ensuring that citizens understand weather and climate sufficiently to make informed decisions, and these topics are gaining increased attention in K-12 education. The National Research Council recently released A Framework for K-12 Science Education with the expectation that U.S. 12th graders must have a sophisticated knowledge of climate change, including the role of deep time, variability, and computer modeling in the prediction of climate impacts on the planet and human activity. This requirement demands that students extend their understanding of climate change to the past and future, but it is important to recognize that many students know little about prerequisite ideas, such as daily and annual weather and climate processes, and this problem must be addressed prior to introducing the complexities of the climate system. In order to diagnose weaknesses in students' foundational understanding of the complex climate system, we primarily assessed a middle school (MS)-level understanding of the core elements of the system, in addition to a high school (HS)-level understanding of seasons. We described grade appropriate, coherent, functioning conceptual models for each targeted idea, and decomposed them into explicit learning goals. We then applied Project 2061's rigorous item development procedure to produce 235 high-quality, misconception-based multiple choice test items. These items were tested with a national sample of approximately 20,000 students, grades 6-12, in two phases (Spring 2010 & 2011). Here we report results from the second phase, including items targeting knowledge about convection, daily and annual air temperature patterns, factors that influence air temperature, and seasons. Overall, HS students outperformed MS students on these items by an average of only 3% (MS:31% correct; HS:34% correct). These data show a few strong misconceptions (e.g., 47% of students think that the North Pole is always angled toward the Sun). But a much more prevalent issue is that most students lack schematic knowledge for any concept tested, as demonstrated by results indicative of random guessing on items that require cognitive demands beyond declarative knowledge. For example, 83% of students know that the maximum height of the sun in the sky above a given place can change during July, but only 32% know both that it changes continuously through the month and could correctly identify if it gets higher or lower. These basic elements of an accurate mental model are needed to explain annual temperature patterns. If students do not have an accurate understanding of processes controlling key elements of the climate system, it is unsurprising that they struggle to comprehend how these elements interact within the system itself. The results of this study underscore the need to 1) ensure that fundamentals are given the necessary attention, even as our expectations for students become increasingly sophisticated; 2) define grade appropriate, coherent, functioning conceptual models for each climate idea and for each grade level; and 3) develop instructional materials that build schematic knowledge.
The profiles of students with significant cognitive disabilities and complex communication needs.

Understanding the characteristics of students with complex communication needs and significant cognitive disabilities is an important first step toward creating the kinds of supports and services required to help them successfully access the general education curriculum, achieve grade-level standards, and improve overall communication competence. The First Contact Survey was designed to collect important information about students with significant cognitive disabilities who were eligible to take the Dynamic Learning Maps™ (DLM(®)) alternate assessment based on alternate achievement standards. From November 2012-May 2013, the survey was used to gather information regarding more than 44,787 students. At that time, the goal was to use the data to inform the development of the DLM assessment. Although the survey includes a wealth of information regarding this large sample of students, the reanalysis of the data reported in the current study focused on the motor, sensory, language, reading, and writing skills of students with significant cognitive disabilities, based on their speech production abilities. Significant differences were identified across each of the domains between students who do and do not use speech with or without aided augmentative and alternative communication.

This study examined how classroom climate affected the performance of students identified as gifted and labeled as underachievers in a secondary science classroom. The goal was to develop an understanding about the complex needs of gifted underachieving students by accessing their "voices" as participants in the education process. Lack of emphasis in the literature regarding gifted underachiever performance and classroom climate provided a need to examine these interactions. However, it was the lack of the gifted underachievers' voices---those with the most at stake in the education process---in the research literature that necessitated examination of their classroom experiences. Case Study methodology guided the theoretical context of the work---informed by phenomenological inquiry to explore learner contextual meaning. Five tenth grade students (4 boys, 1 girl) ranging from 15--17 years of age participated in this qualitative research study. Four frames emerged from the data illuminating participant classroom realities. These were: (a) schools exist to conform students to the educational system; (b) connection to life beyond school is lacking; (c) curriculum needs to engage student interests; and, (d) mutual respect, effort and empathy---caring---on the part of teachers and students needs to occur in the classroom. Analyses led to both pedagogical and research implications. These included: Pedagogical (1) identifying and engaging student interests can enhance gifted underachiever classroom performance; (2) development of communication and negotiation skills are necessary for trust development; (3) students should be included in all phases of curriculum development. Research (1) research in gifted education needs to include student voice as an interpretive frame for understanding learning; (2) peer nomination may be a viable means of identifying gifted underachievers; (3) trust must be negotiated between all participants to develop lucid understanding of classroom events; (4) a tactic used by some gifted students to avoid classroom detection---submersion---needs further research exploration. Many of the results and implications seem to be common sense but are often overlooked in schools. My hope is that this study provides inspiration for additional focus on the needs and interests of learners from their vantage point in the complex milieu of education.

My study examines the development of forms of knowing that arise when students engage in open-ended explorations involving self-directed design and building involving simple materials. It is grounded in an enactivist theoretical perspective on cognition which holds that the creation of action-thought processes for engaging the world is interwoven with the meanings that are constructed for these experiences. A dynamic conception of persons-acting-in-a-setting is fundamental to an enactivist view of cognition. How is understanding enacted in building activity? How does the shape of a problem emerge? How do students enact meaning and understanding when they experience a high degree of physical engagement in building things? What are some characteristics of an enactive learning/teaching environment? My research settings comprise a range of individual, group and classroom engagements of varying lengths over a three and one-half year period. The first research episode involved two grade eight students in an investigation of Paper Towels. The second four month engagement was in a grade nine science class that culminated in the building of a Solar House. The third grade ten episode involved a one month project to build a Mousetrap Powered Car. A fourth Invent a Machine project was conducted in two grade eight science classes taught by the teacher who participated in the Solar House project. Two students were present in three of the four projects. I interviewed one of these students upon completion of his high school physics courses. I found that building is a form of thinking which develops competency in managing complex practical tasks. A triadic relationship of exploration, planning and acting is present. Practical and procedural understandings emerge as students enter and re-enter self-directed problem settings. Thinking patterns depend on the kinds of materials chosen, the ways they are used, and on how students contextualize the problem. Classroom assessment procedures gain complexity and incorporate process components as students become involved in establishing criteria for their work. Contemporary science programs emphasize using performance criteria to evaluate student learning in investigative activity. My study seeks to expand the notion of performance by identifying and portraying essential features of student action-thought.

Postmodern imaginative constructivism for STSE understanding
NASA Astrophysics Data System (ADS)
Robertson, Christian
The influences of science and technology on society and the environment (STSE) have been an integral component of the formal educational curricula for four decades, and yet industrialized countries frequently struggle to balance the benefits of science and technology with the social justice and environmental issues inherent to contemporary society. Canadian citizens often fail to connect scientific and technological understandings with the subtle and yet ubiquitous personal, political, cultural, environmental, and social consequences that result from these understandings. This phenomenological research will explore potential discourses of control within education and society that may preclude authentic, contextual, and meaningful understandings of science and technology relative to their significant consequences, and an imaginative adaptation of Egan's Ironic Understanding and McGinn's Foreground and Background Dimensions to imaginatively express an awareness of postmodern STSE understandings. This research is designed to explore student understandings of how the diverse and complex influences of science and technology affect students through postmodern, imaginative, and constructivist photography. Participants demonstrated a limited Ironic Understanding of STSE, a critical awareness of specific modernist influences, increased personal and affective connections to science and technology, and an awareness of the duality of STSE. Participants' photographic artifacts can be utilized to inform teaching and learning strategies in order to purposefully craft curriculum and lesson plan design for personalized and engaging learning opportunities that incorporate students' awareness of STSE.

Understanding concepts of molecular mechanisms of drug action involves sequential visualization of physiological processes and drug effects, a task that can be difficult at an undergraduate level. Role-play is a teaching-learning methodology whereby active participation of students as well as clear visualization of the phenomenon is used to convey complex physiological concepts. However, its use in teaching drug action, a process that demands understanding of a second level of complexity over the physiological process, has not been investigated. We hypothesized that role-play can be an effective and well accepted method for teaching molecular pharmacology. In an observational study, students were guided to perform a role-play on a selected topic involving drug activity. Students' gain in knowledge was assessed comparing validated pre- and post-test questionnaires as well as class average normalized gain. The acceptance of role-play among undergraduate medical students was evaluated by Likert scale analysis and thematic analysis of their open-ended written responses. Significant improvement in knowledge (P < 0.001) was noted in the pre- to post-test knowledge scores, while a high gain in class average normalized score was evident. In Likert scale analysis, most students (93%) expressed that role-play was an acceptable way of teaching. In a thematic analysis, themes of both strengths and weaknesses of the session emerged. Role-play can be effectively utilized while teaching selected topics of molecular pharmacology in undergraduate medical curricula.
Using rock art as an alternative science pedagogy

Allen, Casey D.
College-level and seventh-grade science students were studied to understand the power of a field index, the Rock Art Stability Index (RASI), for student learning about complex biophysical environmental processes. In order to determine if the studied population was representative, 584 college and seventh-grade students undertook a concept mapping exercise after they had learned basic weathering science via in-class lecture. Of this large group, a subset of 322 college students and 13 seventh-grade students also learned RASI through a field experience involving the analysis of rock weathering associated with petroglyphs. After learning weathering through RASI, students completed another concept map. This was a college population where roughly 46% had never taken a "lab science" course and nearly 22% were from minority (non-white) populations. Analysis of student learning through the lens of actor-network theory revealed that when landscape is viewed as process (i.e. many practices), science education embodies both an alternative science philosophy and an alternative materialistic worldview. When RASI components were analyzed after only lecture, student understanding of weathering displayed little connection between weathering form and weathering process. After using RASI in the field however, nearly all students made illustrative concept maps rich in connections between weathering form and weathering process for all subcomponents of RASI. When taken as an aggregate, and measured by an average concept map score, learning increased by almost 14%, Among college minority students, the average score increase approached 23%. Among female students, the average score increase was 16%. For seventh-grade students, scores increased by nearly 36%. After testing for normalcy with Kolmogorov-Smirnov, t-tests reveal that all of these increases were highly statistically significant at p<0.001. The growth in learning weathering science by minority students, as compared to non-minority students, was also statistically significant at p<0.01. These findings reveal the power of field work through RASI to strengthen cognitive linkages between complex biophysical processes and the corresponding rock weathering forms.

Recent research identifies the most effective learning as active, engaged learning in which students interact with phenomena, other students, and the teacher/leader to derive meaning and construct understanding of their surroundings. "Similarly, an engaging and effective science education goes well beyond the low-level factual recall that is emphasized in many science classes. It must develop the skills that students need to solve complex problems, work in teams, make and recognize evidence-based arguments, and interpret and communicate complex information" (emphasis added). Authentic science research projects provide active, engaged learning in which students interact with authentic science data in an authentic problem-solving context to derive meaning and construct understanding of the world. In formal (and many informal) settings, the teacher/leader is effectively the gatekeeper who determines the learning experiences in which the students will participate. From our experience of nearly a decade and a half of authentic science programming for 5thgrade through early college students working with NASA Mars data, supporting and enabling the teacher is perhaps the most critical and foundational element for designing a successful authentic research experience. Yet, a major barrier to this type of learning are teacher/leaders who are too often not equipped or who lack confidence to succeed in facilitating authentic research projects. The Mars Student Imaging Project has implemented an iterative process of design, testing, and redesign that has identified and implemented critical teacher/leader-enabling elements that have led to increasingly successful adoptions within formal and informal educational settings - allowing more students to gain the benefits of immersive research experience.

Teaching environmental scenarios, such as the availability and transport of pesticides in catchments, may fail with traditional lectures and tutorials due to the complex and synergic interplay of soil, landuse, compounds properties, hydroclimatic forcing and biogeochemical processes. To tackle and pedagogically enter into this complexity, virtual worlds (i.e. computer-based simulated environment) and serious games (i.e. applied games with added pedagogical value) can efficiently improve knowledge and know-how of the future water management stakeholders and scientists. We have developed an e-learning teaching unit using virtual catchments and serious games by gradually adapting the level of complexity depending of the targeted public. The first targeted group is farmers in continuing education centers. We developed a distributed pesticide transport tool in a virtual agricultural catchment to highlight the specific risks of off-site pesticide transport along crop growing season. Students of this first group can interactively define and combine climatic, land-use and soil type scenarios with different pesticides to experiment the components of worst-case situations and to propose best-management practices depending of the involved environmental compartments, i.e. atmosphere, soil, surface water or groundwater. For Master's degree students, we added a level of complexity by adding a specific module focusing on pesticide degradation using cutting-edge approaches. With the compound-specific isotope analysis (CSIA) module students are able to link the 13C/12C signature of pesticides to the ongoing dissipation processes within the catchment. By using and interpreting CSIA data, students can thus efficiently understand the difference between non-destructive (e.g. sorption) and destructive (e.g. bio and abiotic degradation) processes occurring in a catchment. This CSIA tool applied to a virtual agricultural catchment will also allow to distinguish the dilution effect from the degradation effect in complex agricultural catchments receiving pesticides. We anticipate our e-learning teaching unit based on serious game and virtual catchments will help future scientists and stakeholders to better understand and manage pesticides transport within catchments.

Climate change is one of the most challenging problems facing today's global society (e.g., IPCC 2013). While climate change is a widely covered topic in the media, and abundant information is made available through the internet, the causes and consequences of climate change in its full complexity are difficult for individuals, especially non-scientists, to grasp. Science education is a field which can play a crucial role in fostering meaningful education of students to become climate literate citizens (e.g., NOAA 2009; Schreiner et al., 41, 3-50, 2005). If students are, at some point, to participate in societal discussions about the sustainable development of our planet, their learning with respect to such issues needs to be supported. This includes the ability to think critically, to cope with complex scientific evidence, which is often subject to ongoing inquiry, and to reach informed decisions on the basis of factual information as well as values-based considerations. The study presented in this paper focused on efforts to advance students in (1) their conceptual understanding about climate change and (2) their socioscientific reasoning and decision making regarding socioscientific issues in general. Although there is evidence that "knowledge" does not guarantee pro-environmental behavior (e.g. Schreiner et al., 41, 3-50, 2005; Skamp et al., 97(2), 191-217, 2013), conceptual, interdisciplinary understanding of climate change is an important prerequisite to change individuals' attitudes towards climate change and thus to eventually foster climate literate citizens (e.g., Clark et al. 2013). In order to foster conceptual understanding and socioscientific reasoning, a computer-based learning environment with an embedded concept mapping tool was utilized to support senior high school students' learning about climate change and possible solution strategies. The evaluation of the effect of different concept mapping scaffolds focused on the quality of student-generated concept maps, as well as on students' test performance with respect to conceptual knowledge as well as socioscientific reasoning and socioscientific decision making.

The purpose of this research was to understand male nursing students' empathy traits compared with other university students using the systematizing quotient and empathizing quotient questionnaires. Female students have higher empathizing traits than male students. However, when male nursing students were compared with the general population of other male students, they revealed higher empathy traits 3.0 (p < .01) than other males. Empathy plays a significant role in attracting men to a nursing career. Male nurses are not only caring individuals but also have high problem-solving skills in complex environments, demonstrating their strong systemizing characteristics to organize, plan, and implement care. © 2014 Wiley Periodicals, Inc.

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.

Anatomy teaching is seeing a decline in both lecture and laboratory hours across many medical schools in North America. New strategies are therefore needed to not only make anatomy teaching more clinically integrated, but also to implement new interactive teaching techniques to help students more efficiently grasp the complex organization of the human body. Among the difficult anatomical concepts that students struggle to understand, the anatomy of the peritoneal cavity with its complex projections of peritoneum could benefit strongly from new learning aids. In this report, an innovative teaching tool is presented to engage students during both lecture and laboratory, and help them build three-dimensional (3D) mental maps of peritoneal cavity. The model consists of a patchwork of mesenteries and gut made from colored cloth stitched together onto a T-shirt to denote the origin and outflow of each peritoneum projection. As the lecturer wears the life-size model, the students can appreciate the 3D organization of the peritoneal cavity on a living body. In addition, the T-shirt model can be used in parallel with dissection to ensure a strong reinforcement of the spatial understanding of the peritoneal cavity.

Interactive engagement environments are critical to students' conceptual learning gains, and often the instructor is ultimately responsible for the creation of that environment in the classroom. When those instructors are graduate teaching assistants (GTAs), one of the primary ways in which they can promote interactive engagement is through their interactions with students. Much of the prior research on physics GTA-student interactions focuses on GTA training programs (e.g. Ezrailson (2004); Smith, Ward, and Rosenshein (1977)) or on GTAs' specific actions and beliefs (e.g. West, Paul, Webb, and Potter (2013); Goertzen (2010); Spike and Finkelstein (2012a)). Research on students' ideas and behaviors within and surrounding those interactions is limited but important to obtaining a more complete understanding of how GTAs promote an interactive environment. In order to begin understanding this area, I developed the Issues Framework to examine how GTA-student interactions are situated in students' processes during physics problem solving activities. Using grounded theory, the Issues Framework emerged from an analysis of the relationships between GTA-student interactions and the students procedures and expressions of physics content in and surrounding those interactions. This study is focused on introducing the Issues Framework and the insight it can provide into GTA-student interactions and students' processes. The framework is general in nature and has a visually friendly design making it a useful tool for consolidating complex data and quickly pattern-matching important pieces of a complex process. Four different categories of Issues emerged spanning the problem solving process: (1) Getting Started, (2) Solution Approach, (3) Unit Conversions, and (4) Other. The framework allowed for identification of the specific contents of the Issues in each category as well as revealing the common stories of students' processes and how the interactions were situated in those processes in each category. Through the stories, the Issues Framework revealed processes in which students often focused narrowly on procedures with the physics content expressed through their procedures and only sometimes through conceptual discussions. Interactions with the GTA affected changes in students' processes, typically leading students to correct their procedures. The interactions often focused narrowly on procedures as well but introduced conceptual discussions more often than students did surrounding the interactions. Comparing stories across GTAs instead of across categories revealed one GTA who, more often than other GTAs, used conceptual discussion and encouraged students' participation in the interactions. The Issues Framework still needs continued refinement and testing. However, it represents a significant step toward understanding GTA-student interactions from the perspective of students' processes in physics problem solving.

Understanding academic vocabulary is essential to student success in school. Use of academic vocabulary words in writing is considered one of the strongest measures of how well a reader understands a given word. In theory, willingness to use academic vocabulary in writing indicates the complexity of acquiring representations of the word's…

Educating future Americans has long been a debate; with the Next Generation Science Standards (NGSS) now being adopted, climate literacy has become a more dominant discussion in both the classroom and in our society where climate education has often been non-existent or dismal at best. With these new education standards climate literacy is now fundamental to science education, this means understanding climate needs to begin with those headed into the classroom with these future Americans. These educators are expected to be skilled and confident in all subject areas, including science, where they might receive less training. To address this challenge, we have focused on an interdisciplinary approach to climate literacy, which is facilitated through cross-cutting concepts in both Earth and life sciences and parallels NGSS standards. We used the Yale Project on Climate Change Communication to gauge our student's strengths and weaknesses and compare them to the general public's understanding of climate change and complex Earth processes, such as beliefs about climate change, understanding the greenhouse effect, weather versus climate, climate change past and present, impacts and solutions. After a semester of this interdisciplinary course our students felt 95% confident that they are informed about global climate change as compared to 62% of Americans that were surveyed. Our students could define and describe greenhouse effect and 82% of them could classify greenhouse gases as compared to 66% and 45% of Americans respectively. While these non-science, education students were generally more knowledgeable about climate change, the areas where they did not significantly outperform the general public allowed us to refocus our course to aid them in understanding this complex issue where our hopes are that they will be prepared to teach science in their future classroom which will allow their students to be competitive in today's rapidly evolving global economy.

This commentary seeks to expand the dialogue on place-based science education presented in Katie Lynn Brkich's article, where the connections fifth grade students make between their formal earth science curriculum and their lived experiences are highlighted. The disconnect between the curriculum the students are offered and their immediate environment is clear, and we are presented with examples of how they strive to make connections between the content and what they are familiar with—namely their surroundings. "Place" is identified as a term with complex meanings and interpretations, even in the scope of place-based science education, and understanding how the term is used in any given scenario is essential to understanding the implications of place-based education. Is place used as a location, locale or a sense of place? To understand "place" is to acknowledge that for the individual, it is highly situational, cultural and personal. It is just such attributes that make place-based education appealing, and potentially powerful, pedagogically on one hand, yet complex for implementation on the other. The argument is posed that place is particularly important in the context of education about the environment, which in its simplest manifestation, connects formal science curriculum to resources that are local and tangible to students. The incorporation of place in such a framework seeks to bridge the gap between formal school science subjects and students' lived experiences, yet acknowledges the tensions that can arise between accommodating place meanings and the desire to acculturate students into the language of the scientific community. The disconnect between guiding policy frameworks and the reality of the Next Generation Science Standards is addressed opening an avenue for further discussion of the importance of socio-cultural frameworks of science learning in an ever increasing era of accountability.

The aim of the present systematic review was to investigate whether placements in Aboriginal health affect the self-perceived skill in working in Aboriginal health settings and career aspirations of health students, and in particular, aspects of the placement that had the greatest impact. The Embase, Cinahl, ProQuest, Scopus, Informit, Ovid MEDLINE, PsychINFO, and PubMed databases were searched in April/May 2016. Placements of at least 1 week duration in an Aboriginal health setting involving Australian students of medical, nursing, dentistry, or allied health disciplines, with outcomes relating to changes in students' knowledge, attitudes, and/or career aspirations, were included. The search retrieved 1351 papers. Fourteen studies were eligible for inclusion in this review. Narrative synthesis found that work placements in Aboriginal health increased understanding and awareness of Aboriginal culture, promoted deeper understanding of Aboriginal health determinant complexity, increased awareness of everyday racism toward Aboriginal Australians, and enhanced desire to work in Aboriginal health. There is a need for improved teaching and learning scholarship to understand whether placements improve students' skill working with Aboriginal people in health care or increase the likelihood of future employment in these settings. © 2018 John Wiley & Sons Australia, Ltd.

The goal of the work reported here was to help students expand their understanding of antibiotic resistance, the Central Dogma, and evolution. We developed a unit entitled “Ciprofloxacin Resistance in Neisseria gonorrhoeae,” which was constructed according to the principles of scientific teaching by a team of graduate students, science faculty, and instructors. A variety of activities and assessments were used, including a case study, short lectures, and group problem-solving. Implementation of “Ciprofloxacin Resistance in Neisseria gonorrhoeae” in a college freshman seminar suggests these materials are useful in increasing understanding of complex biological topics and improving problem-solving abilities.

Crowdsourcing is the practice of obtaining needed ideas, services, or content by requesting contributions from a large group of people. Amazon Mechanical Turk is a web marketplace for crowdsourcing microtasks, such as answering surveys and image tagging. We explored the limits of crowdsourcing by using Mechanical Turk for a more complicated task: analysis and creation of wind simulations. Our investigation examined the feasibility of using crowdsourcing for complex, highly technical tasks. This was done to determine if the benefits of crowdsourcing could be harnessed to accurately and effectively contribute to solving complex real world engineering problems. Of course, untrained crowds cannot be used as a mere substitute for trained expertise. Rather, we sought to understand how crowd workers can be used as a large pool of labor for a preliminary analysis of complex data. We compared the skill of the anonymous crowd workers from Amazon Mechanical Turk with that of civil engineering graduate students, making a first pass at analyzing wind simulation data. For the first phase, we posted analysis questions to Amazon crowd workers and to two groups of civil engineering graduate students. A second phase of our experiment instructed crowd workers and students to create simulations on our Virtual Wind Tunnel website to solve a more complex task. With a sufficiently comprehensive tutorial and compensation similar to typical crowd-sourcing wages, we were able to enlist crowd workers to effectively complete longer, more complex tasks with competence comparable to that of graduate students with more comprehensive, expert-level knowledge. Furthermore, more complex tasks require increased communication with the workers. As tasks become more complex, the employment relationship begins to become more akin to outsourcing than crowdsourcing. Through this investigation, we were able to stretch and explore the limits of crowdsourcing as a tool for solving complex problems.

Achievement in science depends on a series of factors that characterize the cognitive abilities of the students and the complex interactions between these factors and the environment that intervenes in the formation of students' background. The objective of this study is to: a) investigate reasoning strategies students use in solving stoichiometric problems; b) explore the relation between these strategies and alternative conceptions, prior knowledge and cognitive variables; and c) interpret the results within an epistemological framework. Results obtained show how stoichiometric relations produce conflicting situations for students, leading to conceptual misunderstanding of concepts, such as mass, atoms and moles. The wide variety of strategies used by students attest to the presence of competing and conflicting frameworks (progressive transitions, cf. Lakatos, 1970), leading to greater conceptual understanding. It is concluded that the methodology developed in this study (based on a series of closely related probing questions, generally requiring no calculations, that elicit student conceptual understanding to varying degrees within an intact classroom context) was influential in improving student performance. This improvement in performance, however, does not necessarily affect students' hard core of beliefs.
The effectiveness of 3D animations to enhance understanding of cranial cruciate ligament rupture.

Cranial cruciate ligament (CCL) rupture is one of the most important orthopedic diseases taught to veterinary undergraduates. The complexity of the anatomy of the canine stifle joint combined with the plethora of different surgical interventions available for the treatment of the disease means that undergraduate veterinary students often have a poor understanding of the pathophysiology and treatment of CCL rupture. We designed, developed, and tested a three dimensional (3D) animation to illustrate the pertinent clinical anatomy of the stifle joint, the effects of CCL rupture, and the mechanisms by which different surgical techniques can stabilize the joint with CCL rupture. When compared with a non-animated 3D presentation, students' short-term retention of functional anatomy improved although they could not impart a better explanation of how different surgical techniques worked. More students found the animation useful than those who viewed a comparable non-animated 3D presentation. Multiple peer-review testing is required to maximize the usefulness of 3D animations during development. Free and open access to such tools should improve student learning and client understanding through wide-spread uptake and use.
Student resources for learning physics

Careful observations of learners' reasoning belie simple characterizations of their knowledge or abilities: Students who appear to lack understanding or abilities at one moment show evidence of them at another. Detecting this variability generally requires close examination of what and how students are thinking, moment-to-moment, which makes research difficult. But the findings challenge unitary accounts of intelligence, stages of development, and misconceptions. Joe Redish and others have been working from a more complex theoretical framework of innumerable, fine-grained cognitive structures we call ``resources.'' They are, roughly, ways of thinking people have that may apply or not in any particular moment. (Thinking about energy, for example, may involve resources for understanding location or conservation, or oscillations in time, or differential symmetry.) The variability we observe in student reasoning reflects variability in resource activation. Resources are to models of mind what partons used to be to models of hadrons: We know we should be thinking of entities and dynamics at a smaller scale than we've been considering, even if we don't know their particular properties. Understanding minds in this way has profound implications for research and for teaching.

This study evaluated the cognitive benefits and costs of incorporating biology-textbook and student-generated photographic images into the learning and assessment processes within a 10th grade biology classroom. The study implemented Wandersee's (2000) 20-Q Model of Image-Based Biology Test-Item Design (20-Q Model) to explore the use of photographic images to assess students' understanding of complex biological processes. A thorough review of the students' textbook using ScaleMaster R with PC Interface was also conducted. The photographs, diagrams, and other representations found in the textbook were measured to determine the percentage of each graphic depicted in the book and comparisons were made to the text. The theoretical framework that guided the research included Human Constructivist tenets espoused by Mintzes, Wandersee and Novak (2000). Physiological and cognitive factors of images and image-based learning as described by Robin (1992), Solso (1997) and Wandersee (2000) were examined. Qualitative case study design presented by Yin (1994), Denzin and Lincoln (1994) was applied and data were collected through interviews, observations, student activities, student and school artifacts and Scale Master IIRTM measurements. The results of the study indicate that although 24% of the high school biology textbook is devoted to photographic images which contribute significantly to textbook cost, the teacher and students paid little attention to photographic images other than as aesthetic elements for creating biological ambiance, wasting valuable opportunities for learning. The analysis of the photographs corroborated findings published by the Association American Association for the Advancement of Science that indicated "While most of the books are lavishly illustrated, these representations are rarely helpful, because they are too abstract, needlessly complicated, or inadequately explained" (Roseman, 2000, p. 2). The findings also indicate that applying the 20-Q Model to photographs in biology textbooks can (a) effectively assess students' understanding of complex biological concepts, (b) offer alternative assessment strategies that complement individual learning styles, (c) identify misconceptions, and (d) encourage students to practice metacognition. In addition, once students have learned how to interpret textbook images, application of that knowledge through self-generated biologically relevant digital or print images provides opportunities for increased conceptual understanding.

Living in an unpredictable and ever changing society demands from its' citizens the development of complex competencies that challenges school, education and curriculum. PARSEL, a pan-European Project related to science education, emerges as a contribution to curricular development as it proposes a set of teaching-learning materials (modules) in order to make science classes more popular and relevant in the eyes of the students and as such to increase their interest with school science. The goal of this study was to understand how students evaluate those innovative modules. This paper presents data concerning 134 secondary students, collected through interviews, questionnaires and written documents. A quantitative analysis of the data collected through questionnaires was complemented by a qualitative analysis of the data collected by interviews and written documents. Results show that understanding the relationship between science and daily life, participating in practical activities based on problem solving and developing critical thinking and reasoning were the issues most valued by students.

Genetics literacy is becoming increasingly important as advancements in our application of genetic technologies such as stem cell research, cloning, and genetic screening become more prevalent. Very few studies examine how genetics literacy is applied when reasoning about authentic genetic dilemmas. However, there is evidence that situational features of a reasoning task may influence how students apply content knowledge as they generate and support arguments. Understanding how students apply content knowledge to reason about authentic and complex issues is important for considering instructional practices that best support student thinking and reasoning. In this conceptual report, we present a tri-part model for genetics literacy that embodies the relationships between content knowledge use, argumentation quality, and the role of situational features in reasoning to support genetics literacy. Using illustrative examples from an interview study with early career undergraduate students majoring in the biological sciences and late career undergraduate students majoring in genetics, we provide insights into undergraduate student reasoning about complex genetics issues and discuss implications for teaching and learning. We further discuss the need for research about how the tri-part model of genetics literacy can be used to explore students' thinking and reasoning abilities in genetics.
Novices and Experts in Geoinformatics: the Cognitive Gap.
NASA Astrophysics Data System (ADS)
Zhilin, M.
2012-04-01
Modern geoinformatics is an extremely powerful tool for problem analysis and decision making in various fields. Currently general public uses geoinformatics predominantly for navigating (GPS) and sharing information about particular places (GoogleMaps, Wikimapia). Communities also use geoinformatics for particular purposes: fans of history use it to correspond historical and actual maps (www.retromap.ru), birdwatchers point places where they met birds (geobirds.com/rangemaps) etc. However the majority of stakeholders local authorities are not aware of advantages and possibilities of geoinformatics. The same problem is observed for students. At the same time many professional geoinformatic tools are developed, but sometimes the experts even can't explain their purpose to non-experts. So the question is how to shrink the gap between experts and non-experts in understanding and application of geoinformatics. We think that this gap has a cognitive basis. According to modern cognitive theories (Shiffrin-Atkinson and descending) the information primary has to pass through the perceptual filter that cuts off the information that seems to be irrelevant. The mind estimates the relevance implicitly (unconsciously) basing on previous knowledge and judgments what is important. Then it comes to the working memory which is used (a) for proceeding and (b) for problem solving. The working memory has limited capacity and can operate only with about 7 objects simultaneously. Then information passes to the long-term memory that is of unlimited capacity. There it is stored as more or less complex structures with associative links. When necessary it is extracted into the working memory. If great amount of information is linked ("chunked") the working memory operates with it as one object of seven thus overcoming the limitations of the working memory capacity. To adopt any information it should (a) pass through the perceptual filter, (b) not to overload the working memory and (c) to be structured in the long-term memory. Expert easily adopt domain-specific information because they (a) understand terminology and consider the information to be important thus passing it through the perceptual filter and (b) have a lot of complex domain-specific chunks that are processed by the working memory as a whole thus avoiding to overload it. Novices (students and general public) have neither understanding and feeling importance nor necessary chunks. The following measures should be taken to bridge experts' and novices' understanding of geoinformatics. Expert community should popularize geoscientific problems developing understandable language and available tools for their solving. This requires close collaboration with educational system (especially second education). If students understand a problem, they can find and apply appropriate tool for it. Geoscientific problems and models are extremely complex. In cognitive terms, they require hierarchy of chunks. This hierarchy should coherently develop beginning from simple ones later joining them to complex. It requires an appropriate sequence of learning tasks. There is no necessity in correct solutions - the students should understand how are they solved and realize limitations of models. We think that tasks of weather forecast, global climate modeling etc are suitable. The first step on bridging experts and novices is the elaboration of a set and a sequence of learning tasks and its sequence as well as tools for their solution. The tools should be easy for everybody who understands the task and as versatile as possible - otherwise students will waste a lot of time mastering it. This development requires close collaboration between geoscientists and educators.

Background/aim: Owing to the complex topographical aspects of ophthalmic surgery, teaching with conventional surgical videos has led to a poor understanding among medical students. A novel multimedia three dimensional (3D) computer animated program, called “Ophthalmic Operation Vienna” has been developed, where surgical videos are accompanied by 3D animated sequences of all surgical steps for five operations. The aim of the study was to assess the effect of 3D animations on the understanding of cataract and glaucoma surgery among medical students. Method: Set in the Medical University of Vienna, Department of Ophthalmology, 172 students were randomised into two groups: a 3D group (n = 90), that saw the 3D animations and video sequences, and a control group (n = 82), that saw only the surgical videos. The narrated text was identical for both groups. After the presentation, students were questioned and tested using multiple choice questions. Results: Students in the 3D group found the interactive multimedia teaching methods to be a valuable supplement to the conventional surgical videos. The 3D group outperformed the control group not only in topographical understanding by 16% (p<0.0001), but also in theoretical understanding by 7% (p<0.003). Women in the 3D group gained most by 19% over the control group (p<0.0001). Conclusions: The use of 3D animations lead to a better understanding of difficult surgical topics among medical students, especially for female users. Gender related benefits of using multimedia should be further explored. PMID:16234460
Embedding fundamental care in the pre-registration nursing curriculum: Results from a pilot study.

International evidence suggests nursing is not providing fundamental care consistently or adequately, resulting in poor outcomes for patients and healthcare systems. One possible reason for this inadequate care delivery is nursing education, with fundamental care often implicit or invisible in nursing curricula. To understand how best to teach fundamental care to pre-registration (pre-licensure) students, we developed and piloted a six-week intervention that incorporated into the first-year curriculum a more explicit focus on fundamental care. A conceptual fundamental care framework was used to guide students' learning, and clinical skills sessions were structured to reinforce the framework's conceptual understanding and enable students to practice delivering fundamental care in an integrated manner. The intervention's impact was explored via a pre-post survey and focus groups. The survey demonstrated that the intervention did not affect students' ability to identify patients' fundamental care needs; however, focus groups showed the intervention assisted students in understanding the complexity of fundamental care and its importance to patients' experiences. The pilot provides preliminary evidence on the importance of embedding fundamental care into nursing curricula early and explicitly, and emphasising the integrated nature of such care, particularly through structured debriefs, consistent terminology, and opportunities for students to experience care as a patient.

Genetics is one of the topics or subject matter in biology that are considered difficult. Student difficulties of understanding genetics, can be caused by lack of understanding this concept and the way of teachers teach. Pedagogical Content Knowledge (PCK) is a way to understand the complex relationships between teaching and content taught through the use of specific teaching approaches. The aims of study was to analyze genetic PCK ability profile of prospective biology teacher.13 student of sixth semester Biology education department who learned Kapita Selekta Biologi SMA course, participated in this study. PCK development was measured by CoRes (Content Representation). Before students fill CoRes, students are tested mastery genetic concepts through a multiple-choice test with three tier-test. Data was obtained from the prior CoRes and its revisions, as well as the mastery concept in pre and post test. Results showed that pre-test of genetic mastery concepts average on 55.4% (low category) and beginning of the writing CoRes, student get 43.2% (Pra PCK). After students get lecture and simulating learning, the post-test increased to 63.8% (sufficient category) and PCK revision is also increase 58.1% (growing PCK). It can be concluded that mastery of subject matter could affects the ability of genetic PCK.

New approaches for teaching and assessing scientific inquiry and practices are essential for guiding students to make the informed decisions required of an increasingly complex and global society. The Science Skills approach described here guides students to develop an understanding of the experimental skills required to perform a scientific investigation. An individual teacher's investigation of the strategies and tools she designed to promote scientific inquiry in her classroom is outlined. This teacher-driven action research in the high school biology classroom presents a simple study design that allowed for reciprocal testing of two simultaneous treatments, one that aimed to guide students to use vocabulary to identify and describe different scientific practices they were using in their investigations-for example, hypothesizing, data analysis, or use of controls-and another that focused on scientific collaboration. A knowledge integration (KI) rubric was designed to measure how students integrated their ideas about the skills and practices necessary for scientific inquiry. KI scores revealed that student understanding of scientific inquiry increased significantly after receiving instruction and using assessment tools aimed at promoting development of specific inquiry skills. General strategies for doing classroom-based action research in a straightforward and practical way are discussed, as are implications for teaching and evaluating introductory life sciences courses at the undergraduate level.

Knowing the natural world: The construction of knowledge about evolution in and out of the classroom
NASA Astrophysics Data System (ADS)
Perkins, Alison Emily Havard
Evolution is a central underlying concept to a significant number of discourses in civilized society, but the complexity of understanding basic tenets of this important theory is just now coming to light. Knowledge about evolution is constructed from both formal and "free-choice" opportunities, like television. Nature programs are commonly considered "educational" by definition, but research indicates the narratives often promote creationist ideas about this important process in biology. I explored how nature programs influenced knowledge construction about evolutionary theory using a combination of qualitative and quantitative approaches. Because misconceptions about evolution are common, I examined how students' conceptual ecologies changed in response to information presented in an example of a particularly poor nature film narrative. Students' held a diversity of misconceptions, proximate conceptions, and evolutionary conceptions simultaneously, and many of their responses were direct reflections of the nature program. As a result, I incorporated the same nature program into an experiment designed to examine the effects of narrative and imagery on evolution understanding. After completing an extensive pre-assessment that addressed attitudes and beliefs about science knowledge, students viewed one of four versions of the nature program that varied in the quality of science and imagery presented. The effect of watching different versions was only vaguely apparent in students with a moderate understanding of evolution. The relationship was much more complex among students with a poor understanding of evolution but suggested a negative effect that was more influenced by public discourses about this "controversial" subject than conceptual understanding. The relationships warranted examining learning from the perspective of the consumers of these programs. I surveyed audience beliefs about the educational value of nature programs and found that an overwhelming majority believed the programs were "educational" and designed to teach about nature. The results were particularly alarming because beliefs about the educational value may strongly impact learning outcomes. An informal survey of nature programs aired during a "sweeps" month indicated that poor presentation of science, and specifically evolutionary theory, was indeed the norm. Indeed, nature programs may be contributing to the "deconstruction" of knowledge about evolution both in and out of the classroom.

The Quantitative Reasoning in STEM (QR STEM) project is a state level Mathematics and Science Partnership Project (MSP) with a focus on the mathematics and statistics that underlies the understanding of complex global scientific issues. This session is a companion session to the QR STEM: The Science presentation. The focus of this session is the quantitative reasoning aspects of the project. As students move from understandings that range from local to global in perspective on issues of energy and environment, there is a significant increase in the need for mathematical and statistical conceptual understanding. These understandings must be accessible to the students within the scientific context, requiring the special understandings that are endemic within quantitative reasoning. The QR STEM project brings together interdisciplinary teams of higher education faculty and middle/high school teachers to explore complex problems in energy and environment. The disciplines include life sciences, physics, chemistry, earth science, statistics, and mathematics. These interdisciplinary teams develop open ended performance tasks to implement in the classroom, based on scientific concepts that underpin energy and environment. Quantitative reasoning is broken down into three components: Quantitative Literacy, Quantitative Interpretation, and Quantitative Modeling. Quantitative Literacy is composed of arithmetic concepts such as proportional reasoning, numeracy, and descriptive statistics. Quantitative Interpretation includes algebraic and geometric concepts that underlie the ability to interpret a model of natural phenomena which is provided for the student. This model may be a table, graph, or equation from which the student is to make predictions or identify trends, or from which they would use statistics to explore correlations or patterns in data. Quantitative modeling is the ability to develop the model from data, including the ability to test hypothesis using statistical procedures. We use the term model very broadly, so it includes visual models such as box models, as well as best fit equation models and hypothesis testing. One of the powerful outcomes of the project is the conversation which takes place between science teachers and mathematics teachers. First they realize that though they are teaching concepts that cross their disciplines, the barrier of scientific language within their subjects restricts students from applying the concepts across subjects. Second the mathematics teachers discover the context of science as a means of providing real world situations that engage students in the utility of mathematics as a tool for solving problems. Third the science teachers discover the barrier to understanding science that is presented by poor quantitative reasoning ability. Finally the students are engaged in exploring energy and environment in a manner which exposes the importance of seeing a problem from multiple interdisciplinary perspectives. The outcome is a democratic citizen capable of making informed decisions, and perhaps a future scientist.

This study examined the information-seeking strategies and science content understandings learners developed as a result of using on-line resources in the University of Michigan Digital Library and on the World Wide Web. Eight pairs of sixth grade students from two teachers' classrooms were observed during inquiries for astronomy, ecology, geology, and weather, and a final transfer task assessed learners' capabilities at the end of the school year. Data included video recordings of students' screen activity and conversations, journals and completed activity sheets, final artifacts, and semi-structured interviews. Learners' information-seeking strategies included activities related to asking, planning, tool usage, searching, assessing, synthesizing, writing, and creating. Analysis of data found a majority of learners posed meaningful, openended questions, used technological tools appropriately, developed pertinent search topics, were thoughtful in queries to the digital library, browsed sites purposefully to locate information, and constructed artifacts with novel formats. Students faced challenges when planning activities, assessing resources, and synthesizing information. Possible explanations were posed linking pedagogical practices with learners' growth and use of inquiry strategies. Data from classroom-lab video and teacher interviews showed varying degrees of student scaffolding: development and critique of initial questions, utilization of search tools, use of journals for reflection on activities, and requirements for final artifacts. Science content understandings included recalling information, offering explanations, articulating relationships, and extending explanations. A majority of learners constructed partial understandings limited to information recall and simple explanations, and these occasionally contained inaccurate conceptualizations. Web site design features had some influence on the construction of learners' content understandings. Analysis of data suggests sites with high quality general design, navigation, and content helped to foster the construction of broad and accurate understandings, while context and interactivity had less impact. However, student engagement with inquiry strategies had a greater impact on the construction of understandings. Gaining accurate and in-depth understandings from on-line resources is a complex process for young learners. Teachers can support students by helping them engage in all phases of the information-seeking process, locate useful information with prescreened resources, build background understanding with off-line instruction, and process new information deeply through extending writing and conversation.

This paper contains a research study that investigated the relative efficacy of using both a traditional paper-and-pencil assessment instrument and an alternative, virtual reality (VR) assessment instrument to assist educators and/or instructional designers in measuring learning in a virtual reality learning environment. To this end, this research study investigated assessment in VR, with the goal of analyzing aspects of student learning in VR that are feasible to access or capture by traditional assessments and alternative assessments. The researcher also examined what additional types of learning alternative assessments may offer. More specifically, this study compared the effectiveness of a traditional method with an alternative (performance-based) method of assessment that was used to examine the ability of the tools to accurately evidence the levels of students' understanding and learning. The domain area was electrostatics, a complex, abstract multidimensional concept, with which students often experience difficulty. Outcomes of the study suggest that, in the evaluation of learning in an immersive VR learning environment, assessments would most accurately manifest student learning if the assessment measure matched the learning environment itself. In this study, learning and assessing in the VR environment yielded higher final test scores than learning in VR and testing with traditional paper-and-pencil. Being able to transfer knowledge from a VR environment to other situations is critical in demonstrating the overall level of understanding of a concept. For this reason, the researcher recommends a combination of testing measures to enhance understanding of complex, abstract concepts.
Let's go outside: using photography to explore values and culture in mental health nursing.

Creative and imaginative approaches to mental healthcare education are known to help students explore emotions, empathy and others' experiences, as well as address ambivalence and ambiguity. Very few studies in mental health nursing education specifically utilise photography as a participatory pedagogic tool, with even fewer utilising photography to explore understandings of culture, values and diversity. Photography makes visible complex, collaborative forms of learning and previously unidentified, unarticulated ideas about culture and values. Photography as a critical pedagogic method helps develop critical, politicized understandings of culture and values. Increasing culturally diverse populations means complex and conflicting values have become a common feature in mental health nursing. In education the need to critically examine such topics necessitates creative and engaging pedagogy, and visual methods are readily acknowledged as such. Yet while many studies advocate and demonstrate the value of art-based methods in student learning, very few studies in mental health nursing specifically utilize photography as a participatory pedagogic tool, and fewer still use photography to explore understandings of culture, values and diversity. In this paper, we discuss a qualitative study where mental health nursing students used photography to create images in order to explore their own and often dominant culture and attendant values. Findings suggest that photography makes visible situated, relational and collaborative learning, and surfaces previously unidentified, unarticulated ideas about culture and values. These practices mimic important processes central to mental health nursing practice and contemporaneous understandings of diverse cultures. We argue that photography provides an important resource with which to unearth subjugated knowledge, promote critical understandings of culture and values, and thereby help address inequalities in mental health care. © 2015 John Wiley & Sons Ltd.

Failing a high-stakes assessment at medical school is a major event for those who go through the experience. Students who fail at medical school may be more likely to struggle in professional practice, therefore helping individuals overcome problems and respond appropriately is important. There is little understanding about what factors influence how individuals experience failure or make sense of the failing experience in remediation. The aim of this study was to investigate the complexity surrounding the failure experience from the student's perspective using interpretative phenomenological analysis (IPA). The accounts of three medical students who had failed final re-sit exams, were subjected to in-depth analysis using IPA methodology. IPA was used to analyse each transcript case-by-case allowing the researcher to make sense of the participant's subjective world. The analysis process allowed the complexity surrounding the failure to be highlighted, alongside a narrative describing how students made sense of the experience. The circumstances surrounding students as they approached assessment and experienced failure at finals were a complex interaction between academic problems, personal problems (specifically finance and relationships), strained relationships with friends, family or faculty, and various mental health problems. Each student experienced multi-dimensional issues, each with their own individual combination of problems, but experienced remediation as a one-dimensional intervention with focus only on improving performance in written exams. What these students needed to be included was help with clinical skills, plus social and emotional support. Fear of termination of the their course was a barrier to open communication with staff. These students' experience of failure was complex. The experience of remediation is influenced by the way in which students make sense of failing. Generic remediation programmes may fail to meet the needs of students for whom personal, social and mental health issues are a part of the picture.

Equipping young people with the skills to participate successfully in increasingly complex environments and societies is a central issue of policy makers around the world. Only the understanding of complex socio-environmental systems establishes a basis for making decisions leading to sustainable development. However, OECD Pisa studies indicated, that only a low percentage of 15-year-old students was able to solve straightforward problems. Additionally, students get less interested in natural science education. In Austria "Sparkling Science" projects funded by the Federal Ministry of Science, Research and Economy in Austria target at integrating science with school learning by involving young people into scientific research for the purpose of developing new and engaging forms of interactive, meaningful learning. Within the Sparkling Science Project "Traisen.w3" scientists work together with 15 to 18-year-old students of an Austrian Secondary School over two years to identify and evaluate ecosystem services within the catchment of the river Traisen. One of the aims of the project is to foster system understanding of the youths by multi-modal school activities. To support the development of causal systems thinking, students developed qualitative causal models on processes in the catchment of the river Traisen with an interactive, hierarchically structured learning environment that was developed within the EU-FP7 project "DynaLearn" (http://www.dynalearn.eu) based on qualitative reasoning. Students worked in small groups and were encouraged to interlink entities, processes and simulate the results of the proposed interactions of hydrological, biological, ecological, spatial and societal elements. Within this setting collaborative problem solving competency through sharing knowledge, understanding and different perspectives was developed. Additionally, in several school workshops the ecosystem services concept was used as communication tool to show the multifunctionality of river catchments and to highlight the necessity of a sustainable use. Furthermore a field mapping of a restored and an anthropogenically altered section of the river Traisen was performed by the students in collaboration with the scientists. It aimed on the surveying of specific parameters relevant for the identification of cultural and ecological ecosystem services. To investigate the effects of the different forms of learning on youths' factual, regional and system knowledge, tests were conducted before and after the school activities. The evaluation results of the pre- and post-tests proved that the multi-modal school activities lead to a significantly higher students' knowledge of environmental processes in river landscapes. The analyses of the students` model scenarios for the river catchment Traisen revealed a clear students` understanding of relationships of anthropogenic impacts, morphological and ecological river states and restoration measures. Students` feedback showed high enthusiasm for field work and the application of theoretical knowledge in their regional context. Summarizing, the involvement of secondary school students in the research project "Traisen.w3" can be seen as a successful example of how students` system thinking and motivation for learning can be increased. Ensuring that young people are proficient in system knowledge and understanding also in relation to their own surrounding environment makes it more likely that sustainable considerations are soundly addressed in the future.

Working at scientists' elbows is one suggestion that educators make to improve science education, because such "authentic experiences" provide students with various types of science knowledge. However, there is an ongoing debate in the literature about the assumption that authentic science activities can enhance students' understandings of scientific practice. The purpose of the study is to further address the debate in terms of the ethnographic data collected during an internship programme for high school students right through to their public presentations at the end. Drawing on activity theory to analyse these presentations, we found that students presented scientific practice as accomplished by individual personnel without collaboration in the laboratory. However, our ethnographic data of their internship interaction show that students have had conversations about the complex collaborations within and outside the laboratory. This phenomenon leads us to claim that students experienced authentic science in their internships, but their subsequent representations of authentic science are incomplete. That is, participating in authentic science internships and reporting scientific practice are embedded activities that constitute different goals and conditions rather than unrefracted reflections of one another. The debate on the influence on students' understanding of science practice is not simply related to situating students in authentic science contexts, but also related to students' values and ideology of reporting their understanding of and about science. To help students see these "invisible" moments of science practice is therefore crucial. We make suggestions for how the invisible in and of authentic science may be made visible.

Medical students' reflective journals can be a rich source for understanding what students learn and think about during clinical rotations and can offer educators and mentors insight into students' professional identity formation. The aim of this paper is to ascertain, from reflective accounts, students' development and reactions to psychiatry following their psychiatry clerkship. The patterns, recurrent categories, and themes in 100 psychiatry clerks' reflective journals were analyzed using grounded theory. Constant comparative method was employed to identify and quantify emergent themes and uncover relationships between these themes. The most common "unprompted" themes that students reported were the recognition of the complexity of the illness condition and the fact that the psychiatric patient does not exist in a vacuum (52 %); an acknowledgement of one's respect for the struggle of patients with mental illness (49 %); an expressed or demonstrated empathy for patients (48 %); and a reduced skepticism of the biological basis of mental illness and efficacy of treatments (46 %). Reflective exercises-along with quality mentorship-can be used to understand students' experience with clinical encounters, facilitate change, refine assumptions among students, and promote critical self-assessment and personal growth.
Development and evaluation of a leadership program for veterinary students.
Moore, D A; Klingborg, D J
2001-01-01
Leadership skills are important for many facets of professional life, but no known leadership training programs exist in North American veterinary schools. It was the purpose of this project to develop, deliver, and evaluate a leadership program for first-year veterinary students. Leadership attributes emphasized in the course included effective communication, openness to learning from others, self-awareness, commitment beyond self-interest, motivation, decision making, understanding issue complexity, and team building. The five-day course was delivered to 21 new veterinary students randomly selected just prior to their first-year orientation in the fall of 2000. Participants ranked themselves higher than non-participants in a post-course evaluation on their ability to be effective leaders. Participants reported an increase in self-confidence and a clearer understanding of their leadership roles. Participants also noted new support systems among co-participants and expressed a new ability to consider complex issues more broadly. Most reported that they frequently used enhanced skills in giving and receiving feedback and team building. Other leadership tools identified as valuable included negotiation, group dynamics, a structured approach to problem solving, time management, and an awareness of personal learning style preferences as a means to improve communication.

A core component of public scientific literacy, and thereby informed decision-making, is the ability of individuals to reason about complex systems. In response to students having difficulty learning about complex systems, educational research suggests that conceptual representations, or mental models, may help orient student thinking. Mental models provide a framework to support students in organizing and developing ideas. The PMC-2E model is a productive tool in teaching ideas of modeling complex systems in the classroom because the conceptual representation framework allows for self-directed learning where students can externalize systems thinking. Beyond mental models, recent work emphasizes the importance of facilitating integration of authentic science into the formal classroom. To align these ideas, a university class was developed around the theme of carnivore ecology, founded on PMC-2E framework and authentic scientific data collection. Students were asked to develop a protocol, collect, and analyze data around a scientific question in partnership with a scientist, and then use data to inform their own learning about the system through the mental model process. We identified two beneficial outcomes (1) scientific data is collected to address real scientific questions at a larger scale and (2) positive outcomes for student learning and views of science. After participating in the class, students report enjoying class structure, increased support for public understanding of science, and shifts in nature of science and interest in pursuing science metrics on post-assessments. Further work is ongoing investigating the linkages between engaging in authentic scientific practices that inform student mental models, and how it might promote students' systems-thinking skills, implications for student views of nature of science, and development of student epistemic practices.

The overall aim of the study was to explore health care students´ understanding of core concepts in pharmacology. An interview study was conducted among twelve students in their final semester of the medical program (n = 4), the nursing program (n = 4), and the specialist nursing program in primary health care (n = 4) from two Swedish universities. The participants were individually presented with two pharmacological clinically relevant written patient cases, which they were to analyze and propose a solution to. Participants were allowed to use the Swedish national drug formulary. Immediately thereafter the students were interviewed about their assessments. The interviews were audio-recorded and transcribed verbatim. A thematic analysis was used to identify units of meaning in each interview. The units were organized into three clusters: pharmacodynamics, pharmacokinetics, and drug interactions. Subsequent procedure consisted of scoring the quality of students´ understanding of core concepts. Non-parametric statistics were employed. The study participants were in general able to define pharmacological concepts, but showed less ability to discuss the meaning of the concepts in depth and to implement these in a clinical context. The participants found it easier to grasp concepts related to pharmacodynamics than pharmacokinetics and drug interactions. These results indicate that education aiming to prepare future health care professionals for understanding of more complex pharmacological reasoning and decision-making needs to be more focused and effective.

Language difference among speakers of African American English (AAE) has often been considered language deficit, based on a lack of understanding about the AAE variety. Following Labov (1972), Wolfram (1969), Green (2002, 2011), and others, we define AAE as a complex rule-governed linguistic system and briefly discuss language structures that it shares with general American English (GAE) and others that are unique to AAE. We suggest ways in which mistaken ideas about the language variety add to children's difficulties in learning the mainstream dialect and, in effect, deny them the benefits of their educational programs. We propose that a linguistically informed approach that highlights correspondences between AAE and the mainstream dialect and trains students and teachers to understand language varieties at a metalinguistic level creates environments that support the academic achievement of AAE-speaking students. Finally, we present 3 program types that are recommended for helping students achieve the skills they need to be successful in multiple linguistic environments.
Facilitating trust engenderment in secondary school nurse interactions with students.
Summach, Anne H J
2011-04-01
School nurses are involved in a complex framework of interactions with students, other professionals, parents, and administrators. Trust between nurse and student is critical for interaction effectiveness. The goal of this study was to understand through phenomenology the process of engendering trust in school nurse-high school student interactions. The qualitative approach explored school nurse perceptions of experiences interacting with students, yielding insights into nurse- and setting-based factors contributing to the development of trust. Subthemes within these included key behaviors and attributes enhancing trust engenderment in school nurse-student interactions. Study findings were well supported by the existing nursing and psychological research literature. Nurses that purposefully strive to develop trust in young people will maximize adolescent health results.
Interprofessional communication and medical error: a reframing of research questions and approaches.
Varpio, Lara; Hall, Pippa; Lingard, Lorelei; Schryer, Catherine F
2008-10-01
Progress toward understanding the links between interprofessional communication and issues of medical error has been slow. Recent research proposes that this delay may result from overlooking the complexities involved in interprofessional care. Medical education initiatives in this domain tend to simplify the complexities of team membership fluidity, rotation, and use of communication tools. A new theoretically informed research approach is required to take into account these complexities. To generate such an approach, we review two theories from the social sciences: Activity Theory and Knotworking. Using these perspectives, we propose that research into interprofessional communication and medical error can develop better understandings of (1) how and why medical errors are generated and (2) how and why gaps in team defenses occur. Such complexities will have to be investigated if students and practicing clinicians are to be adequately prepared to work safely in interprofessional teams.
Using Systems Thinking to train future leaders in global health.
Paxton, Anne; Frost, Laura J
2017-07-09
Systems Thinking provides a useful set of concepts and tools that can be used to train students to be effective and innovative global health leaders in an ever-changing and often chaotic world. This paper describes an experiential, multi-disciplinary curriculum that uses Systems Thinking to frame and analyse global health policies and practices. The curriculum uses case studies and hands-on activities to deepen students' understanding of the following concepts: complex adaptive systems, dynamic complexity, inter-relationships, feedback loops, policy resistance, mental models, boundary critique, leverage points, and multi-disciplinary, multi-sectoral, and multi-stakeholder thinking and action. A sample of Systems Thinking tools for analysing global health policies and practices are also introduced.

A Methodological Review of the Assessment of Humanism in Medical Students.
Buck, Era; Holden, Mark; Szauter, Karen
2015-11-01
Humanism is a complex construct that defies simplistic measurement. How educators measure humanism shapes understanding and implications for learners. This systematic review sought to address the following questions: How do medical educators assess humanism in medical students, and how does the measurement impact the understanding of humanism in undergraduate medical education (UME)? Using the IECARES (integrity, excellence, compassion, altruism, respect, empathy, and service) Gold Foundation framework, a search of English literature databases from 2000 to 2013 on assessment of humanism in medical students revealed more than 900 articles, of which 155 met criteria for analysis. Using descriptive statistics, articles and assessments were analyzed for construct measured, study design, assessment method, instrument type, perspective/source of assessment, student level, validity evidence, and national context. Of 202 assessments reported in 155 articles, 162 (80%) used surveys; 164 (81%) used student self-reports. One hundred nine articles (70%) included only one humanism construct. Empathy was the most prevalent construct present in 96 (62%); 49 (51%) of those used a single instrument. One hundred fifteen (74%) used exclusively quantitative data; only 48 (31%) used a longitudinal design. Construct underrepresentation was identified as a threat to validity in half of the assessments. Articles included 34 countries; 87 (56%) were from North America. Assessment of humanism in UME incorporates a limited scope of a complex construct, often relying on single quantitative measures from self-reported survey instruments. This highlights the need for multiple methods, perspectives, and longitudinal designs to strengthen the validity of humanism assessments.

This study examines the effect of increasing the visual complexity used in computer assisted instruction in general chemistry. Traditional recitation instruction was used as a control for the experiment. One tutorial presented a chemistry topic using 3-D animation showing molecular activity and symbolic representation of the macroscopic view of a chemical phenomenon. A second tutorial presented the same topic but simultaneously presented students with a digital video movie showing the phenomena and 3-D animation showing the molecular view of the phenomena. This experimental set-up was used in two different experiments during the first semester of college level general chemistry course. The topics covered were the molecular effect of heating water through the solid-liquid phase change and the kinetic molecular theory used in explaining pressure changes. The subjects used in the experiment were 236 college students enrolled in a freshman chemistry course at a large university. The data indicated that the simultaneous presentation of digital video, showing the solid to liquid phase change of water, with a molecular animation, showing the molecular behavior during the phase change, had a significant effect on student particulate understanding when compared to traditional recitation. Although the effect of the KMT tutorial was not statistically significant, there was a positive effect on student particulate understanding. The use of computer tutorial also had a significant effect on student attitude toward their comprehension of the lesson.
Model-Based Approaches for Teaching and Practicing Personality Assessment.
Blais, Mark A; Hopwood, Christopher J
2017-01-01
Psychological assessment is a complex professional skill. Competence in assessment requires an extensive knowledge of personality, neuropsychology, social behavior, and psychopathology, a background in psychometrics, familiarity with a range of multimethod tools, cognitive flexibility, skepticism, and interpersonal sensitivity. This complexity makes assessment a challenge to teach and learn, particularly as the investment of resources and time in assessment has waned in psychological training programs over the last few decades. In this article, we describe 3 conceptual models that can assist teaching and learning psychological assessments. The transtheoretical model of personality provides a personality systems-based framework for understanding how multimethod assessment data relate to major personality systems and can be combined to describe and explain complex human behavior. The quantitative psychopathology-personality trait model is an empirical model based on the hierarchical organization of individual differences. Application of this model can help students understand diagnostic comorbidity and symptom heterogeneity, focus on more meaningful high-order domains, and identify the most effective assessment tools for addressing a given question. The interpersonal situation model is rooted in interpersonal theory and can help students connect test data to here-and-now interactions with patients. We conclude by demonstrating the utility of these models using a case example.

The ability to clearly disseminate scientific knowledge is a skill that is necessary for any undergraduate student within the sciences. Traditionally, this is accomplished through the instruction of scientific presentation or writing with a focus on peer-to-peer communication at the expense of teaching communication aimed at a nonscientific audience. One of the ramifications of focusing on peer-to-peer communication has presented itself as an apprehension toward scientific knowledge within the general populace. This apprehension can be seen in a variety of venues, including the traditional media, popular culture, and education, which generally paint scientists as aloof and with an inability to discuss scientific issues to anyone other than other scientists. This paper describes a curriculum designed to teach Introduction to Anatomy and Physiology students the tools necessary for communicating complex concepts that were covered during the semester using approachable language. Students were assessed on their word usage in associated writing activities, the student's ability to reduce complexity of their statements, and performance in an informal scientific presentation to a lay audience. Results showed that this pedagogical approach has increased students' ability to reduce the complexity of their language in both a written and oral format. This, in turn, led to evaluators reporting greater levels of understanding of the topic presented following the presentation.

2013-09-01
Radiation oncology requires a complex understanding of cancer biology, radiation physics, and clinical care. This paper equips the medical student to understand the fundamentals of radiation oncology, first with an introduction to cancer treatment and the use of radiation therapy. Considerations during radiation oncology consultations are discussed extensively with an emphasis on how to formulate an assessment and plan including which treatment modality to use. The treatment planning aspects of radiation oncology are then discussed with a brief introduction to how radiation works, followed by a detailed explanation of the nuances of simulation, including different imaging modalities, immobilization, and accounting for motion. The medical student is then instructed on how to participate in contouring, plan generation and evaluation, and the delivery of radiation on the machine. Lastly, potential adverse effects of radiation are discussed with a particular focus on the on-treatment patient.
Beyond prevalence to process: the role of self and identity in medical student well-being.

Problematic stress levels among medical students have been well established. This stress can lead to depression, suicidal ideation, substance abuse, burnout and cynicism, having a negative effect on students and their patients. We propose to move towards examining the processes underlying well-being in some medical students and vulnerability in others. We draw upon social psychological literature to propose that self-complexity, medical student identity and associated norms all have the capacity to influence medical students' well-being in both positive and negative ways. We identify two key dilemmas facing medical students with regard to the social psychological factors investigated. First, a diverse set of interests and a high level of self-complexity is thought to buffer against the effects of stress and might also be beneficial for medical practitioners, but the intensive nature of medical education makes it difficult for students to pursue outside interests, leading to a strongly focused identity. Second, a strong group identity is associated with high levels of social support and improved well-being, but unhealthy group norms may have a greater influence on individuals who have a strong group identity, encouraging them to engage in behaviours that place their well-being at risk. A model is proposed outlining how these potentially contradictory social psychological processes may combine to impact upon medical students' well-being. There is great scope for investigating the role of self-complexity, identity and norms in the medical education context, with room to investigate each of these factors alone and in combination. We highlight how our proposed model can inform medical educators as to the students who may be most vulnerable to the effects of stress and the potential interventions from which they may benefit. We conclude that social psychological factors make a valuable contribution to understanding the complex issue of well-being in medical education. © 2014 John Wiley & Sons Ltd.

The interactions of 2 focus students with others in their cooperative base groups were examined as the students designed, carried out, and interpreted scientific investigations. These 2 students differed with respect to race, gender, socioeconomic status, and academic achievement. They were alike in that both maintained high levels of motivation and interaction with the scientific problems they faced. Their group interactions were not entirely positive, and the difficulties and inequities they faced are described. The data make manifest that group work is a complex process; educators must be sensitive and responsive to the subtle ways understanding can be enhanced or undermined as a result of group dynamics, which are in turn determined by individual expectations - often unfounded - of others' capacities and behaviors, and perceptions of desired group and individual outcomes. These observations also have implications for how educators help prepare prospective teachers to develop effective pedagogical strategies for teaching diverse students.
Virtual immunology: software for teaching basic immunology.
Berçot, Filipe Faria; Fidalgo-Neto, Antônio Augusto; Lopes, Renato Matos; Faggioni, Thais; Alves, Luiz Anastácio
2013-01-01
As immunology continues to evolve, many educational methods have found difficulty in conveying the degree of complexity inherent in its basic principles. Today, the teaching-learning process in such areas has been improved with tools such as educational software. This article introduces "Virtual Immunology," a software program available free of charge in Portuguese and English, which can be used by teachers and students in physiology, immunology, and cellular biology classes. We discuss the development of the initial two modules: "Organs and Lymphoid Tissues" and "Inflammation" and the use of interactive activities to provide microscopic and macroscopic understanding in immunology. Students, both graduate and undergraduate, were questioned along with university level professors about the quality of the software and intuitiveness of use, facility of navigation, and aesthetic organization using a Likert scale. An overwhelmingly satisfactory result was obtained with both students and immunology teachers. Programs such as "Virtual Immunology" are offering more interactive, multimedia approaches to complex scientific principles that increase student motivation, interest, and comprehension. © 2013 by The International Union of Biochemistry and Molecular Biology.

The Next Generation Science Standards (NGSS) call for 5th grade students to "obtain and combine information about ways individual communities use science ideas to protect Earth's resources and environment". Achieving this, and other objectives in NGSS, will require changes in the educational system for both students and teachers. Teachers need access to high quality instructional materials and continuous professional learning opportunities starting in pre-service education. Students need highly engaging and authentic learning experiences focused on content that is strategically interwoven with science practices. Pre-service and early career teachers, even at the secondary level, often have relatively weak understandings of the complex Earth systems science required for understanding climate change and hold alternative ideas and naïve beliefs about the nature of science. These naïve understandings cause difficulties in portraying and teaching science, especially considering what is being called for in NGSS. The ACLIPSE program focuses on middle school pre-service science teachers and education faculty because: (1) the concepts that underlie climate change align well with the disciplinary core ideas and practices in NGSS for middle grades; and (2) middle school is a critical time for capturing students interest in science as student engagement by eighth grade is the most effective predictor of student pursuit of science in high school and college. Capturing student attention at this age is critical for recruitment to STEM careers and lifelong climate literacy. THE ACLIPSE program uses cutting edge research and technology in ocean observing systems to provide educators with new tools to engage students that will lead to deeper understanding of the interactions between the ocean and climate systems. Establishing authentic, meaningful connections between indigenous and place-based, and technological climate observations will help generate a more holistic perspective on climate change and demonstrate that observing systems can enhance understanding. ACLIPSE materials strive to translate research about climate change effectively into understandable narratives of real world phenomena using ocean data, creating meaningful pathways into ocean-climate science for students in ALL communities.

Despite our national efforts to attract more students to the science, technology, engineering, and mathematics (STEM) fields, the number of students continues to be small. Empirical studies have suggested that in order to actively engage students in the science learning processes, lessons need to be designed which consider student prior experiences and provide a sound curriculum, within an environment promoting social interaction---that is, allowing for sharing and negotiation of those ideas which promote reflective thinking. These premises require an embedded assessment system that continuously provides feedback to both student and teacher. This technique allows adaptation and modification of lessons to better facilitate conceptual understanding. This study focused on the use of constructivist strategies that, when aligned, promoted conceptual understanding while facilitating development of science process skills. Skill development leads to meaningful learning, known to promote a change of attitude toward science. A mixed research design embedded in a case study approach was used to understand the complexity of the variables examined in this study. Both quantitative and qualitative methods of data collection were used to strengthen the validity and interpretation of the findings. Students from one of three ninth-grade physical science classes were selected for this study. The students numbered 29, 13 boys and 16 girls; the majority of these students were of Hispanic background. The analysis of data suggested that the use of constructivist strategies promotes conceptual understanding of science concepts and development of science process skills and a change of attitude towards science. This study concluded that selecting teaching and multiple assessment strategies is vital to engage students in science careers. Due to the limited nature of this case study, the researcher recommends a replication or followup with a different teacher and school, including a control group and student interviews to add validity to student written pieces of work.

Emotional creativity (EC) implies experiencing a complex emotional life, which is becoming increasingly necessary in societies that demand innovation and constant changes. This research studies the relation of EC as a dispositional trait with intrinsic motivation (IM) and academic engagement (AE). A sample of 428 university Chilean students, 36.5% men and 63.5% women, with ages from 18 to 45 years-old (M = 20.37; DT = 2.71). Additionally, the mediating function of class-related positive emotions in this relation is explored. The obtained data indicate that developing high levels of dispositional EC enhances the activation of positive emotions, such as gratitude, love and hope, in the classroom. Furthermore, EC predicts IM and AE of university students by the experience of positive emotions. These results compel us to be aware of the importance that university students can understand the complexity of the emotional processes they undergo. A greater control of these emotions would allow students to maintain higher levels of interest in their studies at the different educational stages and to avoid the risk of school failure.

This study examined the reflection interview as a tool for assessing and facilitating the use of 'systems language' amongst 11th grade students who have recently completed their first year of high school biology. Eighty-three students composed two concept maps in the 10th grade-one at the beginning of the school year and one at its end. The first part of the interview is dedicated to guiding the students through comparing their two concept maps and by means of both explicit and non-explicit teaching. Our study showed that the explicit guidance in comparing the two concept maps was more effective than the non-explicit, eliciting a variety of different, more specific, types of interactions and patterns (e.g. 'hierarchy', 'dynamism', 'homeostasis') in the students' descriptions of the human body system. The reflection interview as a knowledge integration activity was found to be an effective tool for assessing the subjects' conceptual models of 'system complexity', and for identifying those aspects of a system that are most commonly misunderstood.
