目前元素化学实验主要包括试管试验和无机化合物制备两方面的内容。对于其中占有一定比例的试管试验,学生往往感到枯燥无味,零乱,有的学生认为不作实验也能写报告。难怪,当教师提出要以科研性、探索性态度对待元素化学实验时,许多学生认为是说大话,小题大做。如何改变这种情况,上好元素化学实验课?下面谈谈我们近几年来的想法和做法. 一、为学生积极主动地实验创造条件 At present, elemental chemical experiments mainly include two aspects of test tube test and inorganic compound preparation. For those who have a certain proportion of test tube experiments, students often feel boring, messy, and some students think that they can write reports without experimentation. It is no wonder that when teachers propose to treat elemental chemistry experiments with a scientific and exploratory attitude, many students believe that they are talking big and making big mistakes. How to change this kind of situation, the good elemental chemistry experiment class? Let’s talk about our ideas and practices in recent years. First, create conditions for students to actively experiment
