Energy is a central concept in science in every discipline and also an essential player in many of the issues facing people everywhere on the globe. However, studies have shown that by the end of K-12 schooling, most students do not reach the level of understanding required to be able to use energy to make sense of a wide range of phenomena. Many researchers have questioned whether the conceptual foundations of traditional approaches to energy instruction may be responsible for students' difficulties. In response to these concerns, we developed and tested a novel approach to middle school physical science energy instruction that was informed by the recommendations of the Framework for K-12 Science Education (National Research Council, 2012a) and the Next Generation Science Standards (NGSS) (NGSS Lead States, 2013). This new approach differs substantially from more traditional approaches to energy instruction in that it does not require energy forms and it emphasizes connections between energy, systems, and fields that mediate interaction-at-a-distance. We investigated student learning during this novel approach and contrasted it with student learning within a comparable unit based on a more traditional approach to energy instruction. Our findings indicate that students who learned in the new approach outperformed students who learned in the traditional approach in every quantitative and qualitative aspect considered in this study, irrespective of their prior knowledge of energy. They developed more parsimonious knowledge networks in relation to energy that focused primarily around the concept of energy transfer. This study warrants further investigation into the value of this new approach to energy instruction in both middle and high school. 相似文献

In this article we employ whiteness as a conceptual framework to contextualize how faculty develop and implement, and consequently how students experience, service learning. A vignette that illustrates the pervasiveness of whiteness in service learning is followed by an analysis that details how whiteness frames the teaching and learning in this service learning experience. Through this example and analysis, we seek to increase instructors’ capacity and confidence to interrupt the patterns and privileges of whiteness that too often are normalized in service learning. 相似文献

Rapid changes in medical knowledge are forcing continuous adaptation of the basic science courses in medical schools. This article discusses a three‐year experience developing a new Computed Tomography (CT)‐based anatomy curriculum at the Sackler School of Medicine, Tel Aviv University, including describing the motivations and reasoning for the new curriculum, the CT‐based learning system itself, practical examples of visual dissections, and student assessments of the new curriculum. At the heart of this new curriculum is the emphasis on studying anatomy by navigating inside the bodies of various living individuals utilizing a CT viewer. To assess the students’ experience with the new CT‐based learning method, an anonymous questionnaire was administered at the end of the course for three consecutive academic years: 2008/2009, 2009/2010, 2010/2011. Based upon the results, modifications were made to the curriculum in the summers of 2009 and 2010. Results showed that: (1) during these three years the number of students extensively using the CT system quadrupled (from 11% to 46%); (2) students' satisfaction from radiologists involvement increased by 150%; and (3) student appreciation of the CT‐based learning method significantly increased (from 13% to 68%). It was concluded that discouraging results (mainly negative feedback from students) during the first years and a priori opposition from the teaching staff should not weaken efforts to develop new teaching methods in the field of anatomy. Incorporating a new curriculum requires time and patience. Student and staff satisfaction, along with utilization of the new system, will increase with the improvement of impeding factors.

In this article we introduce a “head and heart” approach to community-engaged scholarship. Through the literatures of Aboriginal scholarship and engaged scholarship we reflect on a community-university research and program development project undertaken in response to health and education concerns of Aboriginal people in Canada. We suggest that the head and heart approach was crucial to the program’s success and provides access to an ethical space where multiple worldviews are recognized and where the importance of relational accountability becomes evident. We then examine the implications of this approach for engaged scholarship and higher education practices. 相似文献

This paper explores the hypothesis that embedding a laboratory activity into a virtual environment can provide a richer experimental context and hence improve the understanding of the relationship between a theoretical model and the real world, particularly in terms of the model's strengths and weaknesses. While an identified learning objective of laboratories is to support the understanding of the relationship between models and reality, the paper illustrates that this understanding is hindered by inherently limited experiments and that there is scope for improvement. Despite the contextualisation of learning activities having been shown to support learning objectives in many fields, there is traditionally little contextual information presented during laboratory experimentation. The paper argues that the enhancing laboratory activity with contextual information affords an opportunity to improve students’ understanding of the relationship between the theoretical model and the experiment (which is effectively a proxy for the complex real world), thereby improving their understanding of the relationship between the model and reality. The authors propose that these improvements can be achieved by setting remote laboratories within context-rich virtual worlds. 相似文献

The impact of perceived wellness on a range of external load parameters, rating of perceived exertion (RPE) and external load:RPE ratios, was explored during skill-based training in Australian footballers. Fifteen training sessions involving 36 participants were analysed. Each morning before any physical training, players completed a customised perceived wellness questionnaire (sleep quality, fatigue, stress, mood and muscle soreness). Microtechnology devices provided external load (average speed, high-speed running distance, player load and player load slow). Players provided RPE using the modified Borg category-ratio 10 RPE scale. Mixed-effect linear models revealed significant effects of wellness Z-score on player load and player load slow. Effects are reported with 95% confidence limits. A wellness Z-score of ?1 corresponded to a ?4.9 ± 3.1 and ?8.6 ± 3.9% reduction in player load and player load slow, respectively, compared to those without reduced wellness. Small significant effects were also seen in the average speed:RPE and player load slow:RPE models. A wellness Z-score of ?1 corresponded to a 0.43 ± 0.38 m·min?1 and ?0.02 ± 0.01 au·min?1 change in the average speed:RPE and player load slow:RPE ratios, respectively. Magnitude-based analysis revealed that the practical size of the effect of a pre-training perceived wellness Z-score of ?1 would have on player load slow was likely negative. The results of this study suggests that monitoring pre-training perceived wellness may provide coaches with information about the intensity of output that can be expected from individual players during a training session. 相似文献

The infinitely small and the infinitely large are essential in calculus. They have appeared throughout its history in various
guises: infinitesimals, indivisibles, differentials, evanescent quantities, moments, infinitely large and infinitely small
magnitudes, infinite sums, power series, limits, and hyperreal numbers. And they have been fundamental at both the technical
and conceptual levels – as underlying tools of the subject and as its foundational underpinnings. We will consider examples
of these aspects of the infinitely small and large as they unfolded in the history of calculus from the 17th through the 20th centuries. We will also present `didactic observations' at relevant places in the historical account.

This study begins by examining the way in which, in both England and Wales, Religious Education has become implicated in political discussion regarding the role of education in promoting community cohesion. The relationship between taking Religious Education as an examination subject and attitude towards religious diversity (as an affective indicator of community cohesion) is then explored among 3052 14- to 15-year-old students. After controlling for contextual factors (school type and geographical location), personal factors (sex and age), psychological factors (psychoticism, neuroticism and extraversion) and religious factors (Christian affiliation, worship attendance, personal prayer and belief in God), a small but significant positive association was found between taking Religious Education as an examination subject and attitude towards religious diversity. This finding may be interpreted as supporting the view that Religious Education works to promote community cohesion, although the wider debate that the community cohesion agenda has generated among religious educators needs further exploration. 相似文献
