摘要
由于应试教育的强大压力、实验设备的不足以及实验技术的落后等客观因素的影响,导致演示实验仍是教学中的薄弱环节.然而,教学中许多重点、难点问题往往可以通过自制合适的教具来解决.笔者结合自己十几年的教学体会,遵从精简易取、贴近生活、低成本的原则,利用现有资源自制了一系列的低成本教具并应用于教学实践,使得演示实验变得操作容易、演示效果明显,提高了演示实验教学的有效性.
Due to the strong pressure of examination-oriented education ,lack of laboratory equip-ment ,laboratory technology and other objective factors behind ,demonstration experiment is still a weak link .While ,many of the key and difficult problems in teaching can be solved by self-made aids . Based on our ten years of teaching experience ,obeying the principle of easy to take and low-cost ,a se-ries of cost-effective teaching aids was made .These self-made teaching aids could effectively improve demonstration experiment teaching .
