Effect of Air Velocity on Thermal Comfort under Thermal Environment Ramp Changing   总被引：1，自引：0，他引：1  

嵇赟喆  涂光备  孙琳 《天津大学学报(英文版)》2004,10(4):291-296

Set points of the indoor air temperature and relative humidity in short-term staying location were studied. In this condition, the thermal reaction of human body varied with the ramp changes of the environmental thermal parameters. The change rules of about 60 subjects‘ thermal reaction to the ramp change of environment were surveyed, and the effect of air movement on the thermal reaction during transient condition was considered by using a questionnaire. With the experimental results and research findings under stable condition, a way to set environmental parameters of short-time staying location was recommended.  相似文献

Teaching Traditions in Science Teachers’ Practices and the Introduction of National Testing     

Malena Lidar  Martin Karlberg  Jonas Almqvist  Leif Östman  Eva Lundqvist 《Scandinavian Journal of Educational Research》2018,62(5):754-768

Our main interest in this article is to explore whether Swedish teachers changed their teaching and assessment practices in relation to the new national tests in science education that were introduced 2009. Data was collected using a web-distributed questionnaire, which was answered by 407 teachers. The concept of teaching traditions is used to capture patterns of what is emphasized by teachers in terms of goals and content in teaching and the design of the questionnaire was based on the concept of curriculum emphases. The results show two distinct groups of focus, which are compared with two traditions within science education: the Academic and the Moral tradition. The main content where teaching has been changed is in making science more applied than before, where applied not only means the application of science knowledge to practical technical issues, but also to moral and political issues.  相似文献

Conceptual change through vicarious learning in an authentic physics setting   总被引：1，自引：0，他引：1  

Derek A. Muller  Manjula D. Sharma  John Eklund  Peter Reimann 《Instructional Science》2007,35(6):519-533

Recent research on principles of best practice for designing effective multimedia instruction has rarely taken into account students’ alternative conceptions, which are known to strongly influence learning. The goal of this study was to determine how well students of quantum mechanics could learn ‘vicariously’ by watching a student-tutor dialogue based on alternative conceptions. Two video treatments were created to summarize key aspects of quantum tunneling, a fundamental quantum mechanical phenomenon. One video depicted a student-tutor dialogue, incorporating many of the common alternative conceptions on the topic, and resolving inconsistencies in reasoning through discussion. The other presented the same correct physics material in an expository style without alternative conceptions. Second year physics students were randomly assigned to one of the two treatments and were tested before and after watching the video during a lecture. Results show a statistically significant (p < .01) advantage for the learners in the dialogue treatment (d = 0.71). Follow-up interviews of students yielded insight into the affective and cognitive benefits of the dialogue video.  相似文献

Theory Competition and the Process of Change   总被引：1，自引：0，他引：1  

Helen?S.?TimperleyEmail author  Judy?M.?Parr 《Journal of Educational Change》2005,6(3):227-251

The reasons why many educational change initiatives have little impact are often framed in terms of either a poorly designed process on the part of the change initiator, or in terms of problems with the attitudes, skills and/or knowledge of those responsible for implementation. In this paper, we seek to integrate these two perspectives more closely by focusing on their interface and the competing theories frequently held by the change initiators and implementers. This concept of theory competition is illustrated with a case of a national literacy initiative in New Zealand in which the change initiators wished to raise the achievement of low performing students through the development of “learning-centred” leadership in schools and evidence-based practice. The desired outcomes were not achieved because theories about what it means to be a successful leader in such a situation, the data needed to undertake the type of evidence-based analysis envisioned and school personnel beliefs about the target students were understood differently by those responsible for initiating the change and those responsible for implementing it.  相似文献
