Alternative technologies and social studies textbooks     

Stephen T. Kerr 《Publishing Research Quarterly》1992,8(4):33-43

In order to determine the potential of alternative technologies in social studies education, we must understand the goals of such education, the capabilities of the technologies, and teachers’ and students’ responses to new technologies. The author suggests that the new technologies can contribute to the goals of learning about the past, learning about democratic life and institutions, and making students knowledgeable as consumers and producers of information. One major obstacle is a lack of time and money for teachers to experiment with the technologies. Stephen T. Kerr is professor of education in the College of Education at the University of Washington. His research focuses on the application of new technologies in schools and other educational environments, and particularly on the ways in which technology affects the social structure (roles and expectations, instructional patterns, organization) of those institutions. He has done work on human-computer interaction, as well as on how new communication technologies have changed the educational system of the former USSR.  相似文献

三维影相的新算法——修正的直接线性变换     

方兴  谭汀 《体育科学》1992,(4)

通过引入摄影机镜头的内、外方位元素的约束条件,导出了一种修正的DLT(MDLT)方法。该方法用于影片和录相的实测,得到一些有意义的结果。当测量的标定控制点点数较少(6～8个),且这些点的位置在空间和成像面分布不均匀时,用MDLT计算的结果比DLT的结果要好,误差可降低80％以上。  相似文献

Assessing the Utility of Item Response Models: Computerized Adaptive Testing     

G. Gage Kingsbury  Ronald L. Houser 《Educational Measurement》1993,12(1):21-27

How has Item Response Theory helped solve problems in the development and use of computer-adaptive tests? Do we need to balance item content with computer-adaptive tests? Could we use IRT to evaluate unusual responses to computer-delivered tests?  相似文献

提高学校田径接力项目成绩的初探     

黎峰  高兰龙 《山东体育科技》2001,23(3):56-58

接力比赛是一项团体项目，由于竞争激烈．可观赏性很强。在各级田径运动会的比赛中起着举足轻重的作用。一个接力队成绩的好坏也反映出一个学校(团体)的教学与训练的水平。成绩的优劣除了取决于几名运动员的个人短跑成绩外，每个运动员之间的传接棒水平，传接棒成功率的高低，也直接影响着接力队的成绩。  相似文献
