一化学是一门以实验为基础的自然科学。目前,在强调化学实验教学重要意义的同时,还应当特别强调如何改善实验教学,提高实验效果。调查表明:约有三分之一的学生没有正确认识化学实验的重要性,而只是以猎奇的心理看待实验。实验时,无法区分主要现象和次要现象,更无法透过现象看到物质变化的实质;约有三分之二的学生进入实验室时,头脑中没有明确的研索目标,而只是机械地“按方抓药”验证书本知识罢了;更有少数学生以单纯
One chemistry is an experimentally based natural science. At present, while emphasizing the importance of chemistry experiment teaching, it should also give special emphasis to improving experimental teaching and improving experimental results. The survey shows that about one-third of students do not correctly understand the importance of chemical experimentation, but only look at the experiment with a novelty. During the experiment, it was impossible to distinguish the main phenomenon from the secondary phenomenon. It was even more difficult to see through the phenomenon the nature of the substance change. When about two-thirds of the students entered the laboratory, there was no clear research goal in the mind, but only mechanically. “According to the prescription of drugs” to verify the knowledge of books; there are a few students with simple
