怎样在现有条件下提高化学实验的开出率,提高学生的实验能力,培养高素质的人材,是摆在我们面前的重大任务。笔者根据学生过去实验的情况和自己多年的教学实践,摸索出一条改革分组实验的新路子,并取得了明显的效果。现简介如下。1 认真研究教材对实验的安排及意图 中师化学课演示实验的数量较多(平均每节一个),而学生实验的数量较少(平均每章只有两个)。若依此安排进行实验,学生实验室里 How to improve the opening rate of chemical experiments under existing conditions, improve students’ experimental ability, and train high-quality human resources are major tasks before us. Based on the students’ past experimentation and their own years of teaching practice, the author explored a new way of reforming group experiments and achieved significant results. The brief introduction is as follows. 1 Carefully study the arrangement and intent of the teaching materials for the experiment The number of demonstration experiments in the chemistry class of the teacher is more (on average, one in each section), and the number of student experiments is smaller (on average, there are only two in each chapter). If the experiment is arranged in this way, the student’s laboratory
