Teacher development in advanced educational technology

Advanced educational technology promises to improve science teaching and learning. To achieve the posited outcomes, however, teachers must have access to, know how to, have the skills to, and want to use the proposed advanced educational technologies in their teaching. In response, for the past eight years with support from the National Science Foundation, BSCS has conductedENLIST Micros — a teacher development to help science teachers improve their use of microcomputers.ENLIST Micros has three phases — Phase one (1984–1986): BSCS designed, tested, and producedENLIST Micros (Ellis and Kuerbis, 1987, 1989) teacher development materials (text, video, and tutorial software) for helping science teachers improve their use of educational technology. Phase two (1986–1989): BSCS designed, developed, tested, and disseminated a staff development model for helping science teachers integrate educational technology into instruction. Phase three (1989–1992): BSCS established Teacher Development Centers to implement theENLIST Micros teacher development materials and staff development model with science teachers throughout the United States.ENLIST Micros has served more than 1500 science teachers in 15 states. Teachers who have participated in the program have improved their knowledge, attitude, and self-efficacy about computer usage and have improved their use of microcomputers in their science courses. Furthermore, as part of the project, BSCS has described the implementation process and has developed recommendations to support improvements in the use of educational technology in science programs.     

Play: A Paradox for Teacher and Scientist

The objective of this article is to describe the historical development of sport and exercise psychology, with a particular emphasis on the construction and evolution of the “box” through history. The box represents the dominant paradigm that serves as the model for research and application as it evolves through successive historical eras (Kuhn, 1962). Seven historical eras related to the development of sport and exercise psychology are discussed. Of particular interest for this review were individuals whose curiosity and motivation established the roots for the study of sport and exercise psychology, as well as the controversies and tensions in both kinesiology and psychology that shaped the fi eld. Suggestions for the future include a problem-based approach to scholarship and a cultural praxis version of sport and exercise psychology to enhance relevancy and social impact.     

资深专家谈图片编辑

在美国的中小城市,一些中小报刊对版面图片的要求一般不是很重高,图片编辑的工作重心以处理商业图片为主要内容,商业图片的要求比较多,大多用在广告上面,读者所能看到的图片大多是以广告的形式体现在报刊中.     

The Effectiveness of Video as a Learning Tool in On‐line Multimedia Modules

The Broadnet Project produced on‐line interactive multimedia training modules in order to support local small and medium sized (SME) businesses. Two of these modules used videos which were incorporated into the modules and were designed to stream over the Broadnet network. These videos were produced by several different contributors to the project. This report examines the producers’ views and SME trainees’ perceptions of the effectiveness of the videos as training material. Findings suggests that it is the interactive nature of the videos with the clips and questions, and the use of narrative incorporating the information which these trainees found most useful for learning.
