This study provides a historical overview of the development of the instructional television as a tool within the context of science education. The technology was traced from its beginning as experiments in public service broadcasting by universities and television networks, though closed circuit, cable, and commercially produced science-related programming. The use of the technology as a teaching tool is examined in terms of the concept of scientific literacy and the means by which instructional television helped to accomplish the goals of scientific literacy. 相似文献

The nature of project management is change. Even though all knowledge areas in the Project Management Body of Knowledge (PMBOK) are rooted in controlling change, none of these areas specifically addresses the human elements of change. There is a significant distinction between directly controlling change relative to the nonhuman aspects of a project ( change control) and effecting change in the human dimensions of a project through leadership ( change leadership). This article characterizes the distinctive activities of change leadership and change control and their interrelationship throughout the project life cycle. Although distinct, change control and change leadership are interdependent and mutually supporting—both are needed to support project success. 相似文献

Fundamental knowledge of natural history is lacking in many western societies, as demonstrated by its absence in school science curricula. And yet, to meet local and global challenges such as environmental degradation, biodiversity loss and climate change, we need to better understand the living and non-living parts of the natural world. Many have argued passionately for an increased understanding of natural history; others have developed successful pedagogical programmes for applying knowledge of natural history in environmental initiatives. In joining wider calls, we choose here to focus on the educational value afforded by understanding the epistemological bases of natural history and its particular forms of reasoning. We also briefly discuss the ways in which an education in natural history provides the foundation for environmental and social justice efforts that directly affect the lives of young people and their communities. We end by highlighting the ease by which natural history may be incorporated in learning opportunities both in and outside of the classroom. 相似文献

ABSTRACT Studies in several sports have shown the benefits of adapting the playing environment to fit junior players. Frequently the changes are pragmatic choices based on space constraints or existing line markings, or the result of simple scaling based on stature. In this study, a method of scaling the cricket pitch length is presented which is based on the age-specific size and performance of the bowlers and batters. The objective was a pitch length which enabled young bowlers to bowl good length deliveries while releasing the ball at a more downward angle, similar to elite bowlers. The steeper release angle has the benefit of reducing the sensitivity of the ball flight distance to the variability of ball release. Based on data from county standard under-10 and under-11 players a pitch length of 16.22 yards (14.83 m) was calculated, 19% shorter than previously recommended for under-11s in England. A shorter pitch also increases the temporal challenge for batters, encouraging a wider variety of shots and improved anticipation skills. Pitch lengths scaled in this way to fit the players’ abilities as they develop will enable a more consistent ball release by bowlers and more consistent temporal demand for batters. 相似文献

Instructional quality is associated with better academic outcomes for students. This study aimed to investigate how teachers' job satisfaction was associated with clarity of instruction and cognitive activation as measures of instructional quality. In addition, we investigated whether this association between teachers' job satisfaction and instructional quality was mediated by teacher–student relationships. Drawing on the 2018 Teaching and Learning International Survey (TALIS), we compared participants from both Eastern (N = 27,106; Japan, Taipei, Korea, Shanghai) and Western sociocultural contexts (N = 20,209; Canada, Australia, New Zealand, United States, United Kingdom). Multilevel structural equation modelling results indicated that teachers' job satisfaction was positively associated with instructional quality across Eastern and Western settings. The relationship between teachers' job satisfaction and instructional quality was partially mediated by better student–teacher relationships. There were some differences between the cultural settings in how job satisfaction correlated with clarity of instruction and cognitive activation. We suggest that these differences may be accounted for by cultural characteristics leading to different approaches to teaching. Our results suggest that teachers' job satisfaction and the quality of classroom-level relationships may be important indicators of positive instructional outcomes. While schools focus on student outcomes, they should also address teachers' job satisfaction and prioritise the importance of relationships between teachers and students in classrooms. 相似文献

Research has revealed that individual soccer goalkeepers respond differently to penalty shots, depending on their specific perceptual and motor capabilities. However, it remains unclear whether analogous differences exist between individual penalty takers, and if specialising in penalty taking affects the occurrence of differences between individuals. The present study examined individual differences in penalty shot speed and accuracy for specialists in penalty taking versus non-specialists. Expert specialist field hockey drag flickers and equivalently skilled non-specialists performed drag flicks towards predetermined targets placed in the face of a standard field hockey goal. Comparisons in shot speed and accuracy were made at a group level (specialists vs. non-specialists) as well as between individuals. Results revealed differences in both speed and accuracy between specialists, but only differences in speed between non-specialists. Specialists generated significantly greater shot speed than non-specialists (P < .001) and were more accurate to some, but not all, targets (top left, P < .006, bottom left P < .001). In addition, it was found that in specialists increasing practice correlated with decreasing accuracy. This may indicate that excessive practice could potentially reduce a specialist’s accuracy in shooting towards specific targets. 相似文献
