教师在生物课堂教学中运用电教手段教学,是改进教学方法、提高教学效率的一种有效途径。同时,一切实物都存在双面性,过度使用电教手段,只会对学生产生消极思想,所以,在初中生物课堂中,运用电教手段辅助生物教学,能够加强直观,优化教学过程。提高学生的注意力,激发学生的学习兴趣,培养学生的观察能力创设教学情境,提高记忆效果。所以我们教师应该合理的使用电教手段,正确合理地使用电教媒体,充分发挥不同电教媒体的功能,提高课堂教学效率。
Teachers in the biological classroom teaching the use of teaching methods of electric teaching is to improve teaching methods and improve teaching efficiency is an effective way. At the same time, all things are double-sided. Too much use of audio-visual means can only produce negative thoughts to the students. Therefore, in the junior middle school biology class, using the means of audio-visual education to assist biology teaching can strengthen the visualization and optimize the teaching process. Improve students’ attention, stimulate students’ interest in learning, develop students’ observation ability, create teaching situations and improve memory effect. Therefore, our teachers should use audio-visual means rationally, use audio-visual media correctly and reasonably, give full play to the functions of different audio-visual media, and improve the efficiency of classroom teaching.
