Jump Distance Increases While Carrying Handheld Weights: Impulse, History, and Jump Performance in a Simple Lab Exercise

This laboratory exercise is designed to provide an understanding of the mechanical concept of impulse as it applies to human movement and athletic performance. Students compare jumps performed with and without handheld weights. Contrary to initial expectation, jump distance is increased with moderate additional weights. This was familiar to Ancient Greek athletes where halteres were a part of the original Olympic jumping sports. The effectiveness of this laboratory was assessed with a prelab questionnaire evaluating understanding of the concepts relevant to jumping mechanics and a postlab questionnaire assessing understanding of the same principles in the context of a different but mechanically analogous circumstance, that of throwing. Results indicate that understanding improved significantly as a result of participation in the laboratory exercise.     

The Teacher Training Program for Doctoral Candidates in History at the University of Wisconsin

Abstract

One question of interdisciplinary education is how to encourage students to draw connections between disciplines and to engage in critical thinking. The authors developed a team-taught interdisciplinary course examining the history and literature of modern revolutions. The first time the course was given, students had difficulty making interdisciplinary connections and did not critically re-examine their assumptions. The authors restructured the course, re-thinking its emphasis, procedures, texts, and assignments, with substantial positive results. They also learned that teachers need to reassess their own ideology and teaching strategies to make interdisciplinary education effective.     

Emerging communities of practice: collaboration and communication in action research

This article chronicles the experiences of Dialogues in Methods of Education (DIME), a group of school and university faculty. Over the past 22 years, DIME members have studied together how to improve their own teaching practices through research, the sharing of ideas and mutual support. They have also engaged in critical analysis of the disciplinary and institutional forces shaping their work. The history of DIME shows the importance of accommodating difference as well as providing mutual support for long-term collaborations.     

Visual Preferences and Environmental Protection: Evolutionary aesthetics applied to environmental education

Assuming that experiencing one's natural environment is part of environmental education, against the background of evolutionary aesthetics, it is unlikely that a direct connection between experiencing nature and a 'proper' environmental behaviour exists. Nevertheless,certain elements of a person's natural environmentcause genetically pre-disposed positive or negative feelings, that can contribute directly to environmental education didactics: the desire to preserve nature and the interest in environmental protection can be raised and increased by making use of these aesthetic feelings.     

Three-Dimensional Printing of Archived Human Fetal Material for Teaching Purposes

The practical aspect of human developmental biology education is often limited to the observation and use of animal models to illustrate developmental anatomy. This is due in part to the difficulty of accessing human embryonic and fetal specimens, and the sensitivity inherent to presenting these specimens as teaching materials. This report presents a new approach using three-dimensional (3D) printed replicas of actual human materials in practical classes, thus allowing for the inclusion of accurate examples of human developmental anatomy in the educational context. A series of 3D prints have been produced from digital data collected by computed tomography (CT) imaging of an archived series of preserved human embryonic and fetal specimens. The final versions of 3D prints have been generated in a range of single or multiple materials to illustrate the progression of human development, including the development of internal anatomy. Furthermore, multiple copies of each replica have been printed for large group teaching. In addition to the educational benefit of examining accurate 3D replicas, this approach lessens the potential for adverse student reaction (due to cultural background or personal experience) to observing actual human embryonic/fetal anatomical specimens, and reduces the potential of damage or loss of original specimens. This approach, in combination with ongoing improvements in the management and analysis of digital data and advances in scanning technology, has enormous potential to allow embryology students access to both local and international collections of human gestational material.

University science students as curriculum planners,teachers, and role models in elementary school classrooms

Project SEARCH (Science Education and Research for CHildren) is an outreach program designed to teach science and to foster positive attitudes toward science. Through the project, university science students bring activity-based learning, plus materials and content expertise, to local classrooms and after-school programs. Using observations, surveys, and interviews, we examined the experiences of these students as curriculum planners, teachers, and role models for the children. We found that teachers value the enthusiasm and the resources provided by the SEARCH students. Children were engaged in the activities and looked forward to the students' visits. They also see them as positive and diverse models for the role of scientist. But there were often problems in the areas of preparation, scheduling, and communication, and the classroom activities often replicated traditional didactic lessons. The SEARCH experience highlights both the value of providing diverse and challenging experiences for children, and the need for dialogue and reflection on those experiences. Despite several concerns, the SEARCH model is one that deserves expansion and further study as it is extended into new settings. © 1997 John Wiley & Sons, Inc. J Res Sci Teach 34 : 69–88, 1997.     

Utility of Feedback Has a Greater Impact on Learning than Ease of Decoding

While feedback is a key facilitator of learning, researchers have yet to determine the ideal feedback process for optimal performance in learners. The current study investigates the combined effects of ease of decoding, and utility of feedback during learning. Accuracy and rate of learning were recorded alongside changes to the feedback related negativity (FRN), an event‐related potential (ERP) elicited by feedback stimuli. This study investigates the FRN within the context of future‐focused directive feedback (DF), in addition to past‐focused evaluative feedback (EF) typically seen in the neuroscience literature. Results indicate a main effect of utility together with an interaction with ease of decoding on the accuracy data, but only the main effect of utility on learning rate. DF produced an FRN, like EF, which was then larger during high‐utility feedback, specifically following negative EF or when hard‐to‐decode. Implications and future research directions are discussed.
