近几年,高中思想政治课可谓高投入、低产出的低效教学,其直接原因是:思想政治课仍然没有改变满堂灌的死气沉沉的课堂教学气氛。 要提高思想政治课教学的实效,关键在于激发学生的学习积极性和主动性,调动学生的学习兴趣。这就需要改革课堂教学结构,使学生能有更多的机会积极观察、思考,做到脑、口、手并动,积极参与教学的双边活动。充分运用电教媒体,便是优化课堂教学结构的有效途径。 加拿大学者马歇尔·麦克卢汉(Marshall Mcluhan)在《媒体通论:人体的延伸》(1964年)一书中说:“媒体是人体的延伸。”比如,无线电广播、扩音系统相当于人的耳朵的延伸;摄影机、摄像机相当于人的视觉的延伸;电

The extension; camera, camera is equivalent to the extension of human vision;
