电教中最常用的仪器是投影仪.利用投影放大的特点,能增加小实验、小仪器的可见度.如液体压强计的读数、游标卡尺的结构、启辉器的工作过程等.投影的物理现象或过程直观生动、变化清晰.现代教育理论认为:教学中学生个性的心理发展至关重要,采用电教手段的灵活多变,对个性心理有着积极的影响.所以用投影仪能扩大教学容量,有效地推进教学的进度. 本文是探讨如何利用投影仪的影视功能,借鉴动画编辑的表现处理技法,进一步提高电教的科学性、艺术性,使电化教育在教学能充分发挥它的作用.
The most commonly used instrument in audio-visual education is a projector. Using the characteristics of projection amplification can increase the visibility of small experiments and small instruments, such as readings of a liquid pressure gauge, the structure of a vernier caliper, the working process of a starter, etc. The physical phenomenon of projection may be The process is intuitive and vivid, and the changes are clear. The modern education theory believes that the psychological development of student personality in teaching is very important. The flexible use of audio-visual teaching methods has a positive impact on personality psychology. Therefore, the use of projectors can expand teaching capacity and effectively promote The progress of teaching. This article is to explore how to use the projector’s film and television functions, drawing on the animation editing performance processing techniques, to further improve the science and technology of audio-visual education, so that the audio-visual education can fully play its role in teaching.
