近几年来,我们在加强实验和改进实验教学方面做了一些工作,例如学生实验由传统的两人一组改为单人实验即“一人一组”实验(参看《化学教育》1985年第6期)以及试行实验考查等。随着化学教学改革的深入开展,我们发现实验室工作已成为教改能否顺利进行的一个基础条件。侧如如果想尽可能将演示实验改为随堂实验,就要大大增加准备实验的数量;将部分验证式学生实验改为探索式学生实验,也必须严格按照教材进度及时准备好实验;此外再增加些必要的补 In recent years, we have done some work in strengthening experiments and improving experimental teaching. For example, we have changed from a traditional two-person experiment to a single-person experiment called a “one-man-one-experiment” (see Chemistry Education, No. 6, 1985 Period) and pilot experiments to examine and so on. With the deepening of chemistry teaching reform, we found that laboratory work has become a basic condition for the successful reform of teaching reform. For example, if we want to change the demonstration experiment to a random experiment as much as possible, we should greatly increase the number of preparation experiments. When we change some of the verification student experiments to exploratory student experiments, we must also prepare the experiments in strict accordance with the progress of the teaching materials.
