Modeling and measuring epistemic cognition: A qualitative re-investigation     

Jeffrey A. Greene  Seung B. Yu 《Contemporary educational psychology》2014

Since Perry first proposed that students’ beliefs about knowledge and knowing were an important aspect of learning, there has been a proliferation of models of epistemic cognition, and empirical studies of how epistemic cognition relates to learning. Unfortunately, the dominant means of measuring epistemic cognition, self-report instruments, have numerous psychometric problems. These problems prompted us to return to interview methods used by Perry and other seminal researchers, to investigate the degree to which current epistemic cognition models aligned with novices’ and experts’ cognition. Using an exploratory, multiple case qualitative design, we interviewed middle school students and university professors from two domains, biology and history. We found numerous ways in which the current conceptualizations and measures of beliefs about knowledge and knowing may need to be altered. Our recommendations range from the revision of item wordings to a complete rethinking of the very idea of domain-specificity in epistemic cognition research.  相似文献   

The Science of Pizza: The Molecular Origins of Cheese,Bread, and Digestion Using Interactive Activities for the General Public     

Amy C. Rowat  Daniel Rosenberg  Kathryn A. Hollar  Howard A. Stone 《Journal of Food Science Education》2010,9(4):106-112

Abstract: We describe a presentation on the science of pizza, which is designed for the general public including children ages 6 and older. The presentation focuses on the science of making and digesting cheese and bread. We highlight 4 major scientific themes: (1) how macromolecules such as carbohydrates and proteins are composed of atoms and small molecules; (2) how macromolecules interact to form networks in bread and cheese; (3) how microbes contribute to the texture of bread; and (4) how enzymes break down macromolecules during digestion. Using live demonstrations and interactive exercises with children in the audience, we provide simple explanations of the scientific principles related to these themes that are essential for understanding how to make pizza, and what happens when we eat it. This general approach can be adapted to a variety of informal and classroom settings focused on sharing the excitement of scientific discovery and understanding with students and the public.  相似文献   

Announcing the Engagement of Sudoku: An In‐Class Genetic Algorithm Game          下载免费PDF全文

Kathryn W. Ernstberger  M.A. Venkataramanan 《Decision Sciences Journal of Innovative Education》2018,16(3):185-196

This teaching brief describes an engaging, in‐class exercise that introduces genetic algorithms as well as advanced Excel functions and capabilities by modeling the familiar Sudoku puzzle. Student groups are first asked to manually solve a given puzzle and then translate that solution methodology to a spreadsheet model. This exercise can be used to build classroom community and as a launching point for the content area of genetic algorithms and the use of Evolutionary Solver.  相似文献   

School board decision-making and the elimination of sport participation fees     

Kathryn L. Heinze  Jennifer Zdroik 《Sport, Education and Society》2018,23(1):53-67

Public schools in the US are increasingly charging ‘pay-to-play’ fees for participating in sports. Although these fees can cause reductions in participation, particularly for children from lower-income families, pay-to-play has become a legitimate practice within the field of public education. This study examines what leads some school districts to abandon sport participation fees, despite the trend in adoption. In particular, using a qualitative, case study approach, we investigate why and how school districts eliminate pay-to-play. We found that the decision to terminate pay-to-play in the ‘Ellis’ district was shaped by the community culture and district leadership. Our findings are supported by data on surrounding school districts. This study contributes to the literatures on institutional change; privatization of health, sport and physical education; and school board decision-making. The findings also shed light on the local context of pay-to-play—a policy that has implications for social equity and youth health and wellness.  相似文献   

Focused Multisensory Anatomy Observation and Drawing for Enhancing Social Learning and Three-Dimensional Spatial Understanding     

Leonard Shapiro  Kathryn Bell  Kallpana Dhas  Toby Branson  Graham Louw  Iain D. Keenan 《Anatomical sciences education》2020,13(4):488-503

The concept that multisensory observation and drawing can be effective for enhancing anatomy learning is supported by pedagogic research and theory, and theories of drawing. A haptico-visual observation and drawing (HVOD) process has been previously introduced to support understanding of the three-dimensional (3D) spatial form of anatomical structures. The HVOD process involves exploration of 3D anatomy with the combined use of touch and sight, and the simultaneous act of making graphite marks on paper which correspond to the anatomy under observation. Findings from a previous study suggest that HVOD can increase perceptual understanding of anatomy through memorization and recall of the 3D form of observed structures. Here, additional pedagogic and cognitive underpinnings are presented to further demonstrate how and why HVOD can be effective for anatomy learning. Delivery of a HVOD workshop is described as a detailed guide for instructors, and themes arising from a phenomenological study of educator experiences of the HVOD process are presented. Findings indicate that HVOD can provide an engaging approach for the spatial exploration of anatomy within a supportive social learning environment, but also requires modification for effective curricular integration. Consequently, based on the most effective research-informed, theoretical, and logistical elements of art-based approaches in anatomy learning, including the framework provided by the observe–reflect–draw–edit–repeat (ORDER) method, an optimized “ORDER Touch” observation and drawing process has been developed. This is with the aim of providing a widely accessible resource for supporting social learning and 3D spatial understanding of anatomy, in addition to improving specific anatomical knowledge.  相似文献   

Formative Evaluation of Computer‐Based Training For a University Financial System     

Kathryn M. Fischer  Wilhelmina C. Savenye  Howard J. Sullivan 《Performance Improvement Quarterly》2002,15(1):11-24

This article describes a formative evaluation of a one‐day introductory computer‐based training (CBT) course for a new on‐line financial and purchasing system at a large public university. The purposes of the evaluation were to evaluate the effectiveness of the training and to identify appropriate revisions and incorporate them into the training program. Participants were 78 university employees who were likely future users of the financial and purchasing system. The mean score on an on‐line performance posttest that simulated real‐work tasks was 94%, and the mean on a 40‐item knowledge posttest covering the CBT content was 74%. Learner attitudes toward the course were positive, averaging 4.4 on a 5‐point scale. Formative evaluation of the program resulted in revisions that had the potential to improve its effectiveness and provided evidence of the value of ongoing formative evaluation of workplace training.  相似文献   

Leveraging complexity frameworks to refine theories of engagement: Advancing self-regulated learning in the age of artificial intelligence     

Jonathan C. Hilpert  Jeffrey A. Greene  Matthew Bernacki 《British journal of educational technology : journal of the Council for Educational Technology》2023,54(5):1204-1221

Capturing evidence for dynamic changes in self-regulated learning (SRL) behaviours resulting from interventions is challenging for researchers. In the current study, we identified students who were likely to do poorly in a biology course and those who were likely to do well. Then, we randomly assigned a portion of the students predicted to perform poorly to a science of learning to learn intervention where they were taught SRL study strategies. Learning outcome and log data (257 K events) were collected from n = 226 students. We used a complex systems framework to model the differences in SRL including the amount, interrelatedness, density and regularity of engagement captured in digital trace data (ie, logs). Differences were compared between students who were predicted to (1) perform poorly (control, n = 48), (2) perform poorly and received intervention (treatment, n = 95) and (3) perform well (not flagged, n = 83). Results indicated that the regularity of students' engagement was predictive of course grade, and that the intervention group exhibited increased regularity in engagement over the control group immediately after the intervention and maintained that increase over the course of the semester. We discuss the implications of these findings in relation to the future of artificial intelligence and potential uses for monitoring student learning in online environments.
