1、传统实验教学中的弊端教学大纲规定:初中物理开设实验共125个。其中教师演示实验(以下简称“演示实验”)103个。学生分组实验(以下箭简称“学生实验”)22个。按初二、初三每学年96课时,共192课时计算,平均每课时开出实验0.65个。这个标准不算低,与我们国家“文革”前相比(文革前每课时约开出实验0.4个)增加了近60%。与当代一些教育发达国家的同年级同学科教材比,也不算少。但是传统的实验课堂教学,存在着明显的缺陷与不足。
1. Disadvantages in the traditional experimental teaching The syllabus stipulates that there are 125 experiments for junior high school physics. There are 103 teachers demonstrating experiments (hereinafter referred to as “demonstration experiments”). There are 22 student grouping experiments (hereinafter referred to as “student experiments”). According to the 96 hours of the first two days and the third year of the school year, a total of 192 hours of time are calculated, and an average of 0.65 tests are conducted per lesson. This standard is not low, and it is nearly 60% higher than before our country’s “Cultural Revolution” (about 0.4 experiments per class before the Cultural Revolution). Compared with the textbooks of the same grade in the same year in some educational developed countries, it is not too small. However, there are obvious defects and deficiencies in traditional experimental classroom teaching.
