教材中“板块构造”理论性强,内容也比较多,采用常规的教学方法,教学效果总不够理想。笔者利用“我们生活在动荡的星球上”等录像片,根据教学需要,对其中的片断进行剪辑和处理,编制了4组长约5分钟的教学录像片。运用于课堂教学中,效果很好。 一、从引言开始到大陆漂移说 简短的引出了大陆漂移说,这时,请学生注意看录像,彩色屏幕上形象地展现了从2亿年前直到现代的大陆漂移过程。片长约1分钟。采用重复录像的方法,不倒录像带可连续再现一次,不仅加深了学生印象,而 The “plate tectonics” in the textbooks is theoretically strong and content is relatively large. Using conventional teaching methods, the teaching results are not always satisfactory. The author made use of videos such as “We live on a turbulent planet” and edited and processed the clips according to the teaching needs. Four groups of teaching videos with a length of about five minutes were compiled. It works well in classroom teaching.

The color screen shows the continental drift from 200 million years ago until modern times. The length of the film is about 1 minute. Using the method of repeated video recording, the video tape can be reproduced continuously without dropping the tape, which not only deepens the student’s impression, but also
