我们有许多初中化学教师常常会看到这样一种现象:学生经过了初中化学课程的学习之后,对化学学习的兴趣大幅下降。其中最能说明这一问题的是:对化学变化和常见物质的实验室制取的兴趣变化。这是因为我们大多数的老师在以往的教学中关注的是学生多记住几个化学方程式,关注的是学生多做一些为应试中考而编制的试题,而不是真正带着学生通过化学实验的探究去学 Many of our junior high school chemistry teachers often see such a phenomenon: students after chemistry courses in junior high school, a sharp decline in interest in chemistry. One of the best explanations for this is the change in interest in chemical changes and laboratory preparation of common substances. This is because most of our teachers are concerned with past teaching that students remember more than one chemical equation and are concerned that students should do more exams for exams instead of actually taking students through chemical experiments Explore to learn
