(一)使用化学实验箱是解决教学中主要问题之一在化学教学中充分利用实验是完成教学任务重要方法之一,但是在实践的过程中限于设备条件与人力的不足,中间遇到不少的困难,首先我们是改装一个实验室。但是初高中四十二个班中的二十八个班有化学课,一个实验室实在不够用,上“单元实习课”也不方便。 (A) the use of chemical experiment box is to solve one of the major problems in teaching Make full use of experiments in chemistry teaching is one of the important ways to complete the task of teaching, but in practice the process is limited to the lack of equipment and manpower, the middle of many The difficulty, first of all, we are a modification of a laboratory. However, there are 28 classes in 42 classes of junior high school with chemistry classes, one laboratory is not enough and the “unit practice class” is also not convenient.
