幻灯教学,作为一种新的强有力的教学手段,已被越来越多的人所重视。它为改进教学方法,帮助学生接受知识和发展智能,开拓了新的途径。几年来,我们从实际出发,因陋就简,运用幻灯进行教学,取得了较好的教学效果,下面谈谈我们的一些做法和体会。 一、形象生动,化难为易 现代科学技术的迅猛发展,要求化学从微观的角度来研究物质的结构。新编中学化学教材已有不少这方面的基础知识。这部份教材的特点是内容多,理论深,难度大。光凭口头讲解和使用黑板粉笔,要使学生明白易懂,是有较大困难的。而运用幻灯进行教学,则能充分显示出形
As a new powerful teaching method, slide show teaching has been paid more and more attention by people.

This part of the teaching materials is characterized by a large amount of content, a deep theory, and great difficulty.
