现代远程教育环境下的教师影像

Teachers' Picture in the Environment of Modern Distance Education

多媒体技术和影像制作技术的提高,使教师影像获得了更大,更丰富的表现空间,而网络技术提供的即时交互功能,更为师生交流对话提供了良好的技术平台。仅从技术层面上说,困扰我们已久的影像教学单向性和封闭性问题应该得到一定程度的解决。但较之于20多年前电视教材,网络环境中的教师影像无论是授课形式、课程结构、表现方法等都并无太大变化。如何设计出更符合远程教育和影像教学特点,符合学生的收视心理和教学规律,符合教师成为学生学习促进者的角色扮演的影像课程,是教师和影像制作人员应该给予高度重视和深入思考的问题。

In terms of technology, the problems of one - way and confined picture instruction should be solved to some extent. Comparing with those of TV teaching materials made in the past two decades, the teachers＇ pictures produced by the web technology have little difference in teaching forms and course structures. How to design the picture instruction and courses that accord with the characteristics of DE and picture instruction, with students＇ viewing psychology and instructional law and with the role performance of teachers as the promoter of students is great task for teachers and picture- makers.
