一、抓态度 学生对待实验的态度如何,是能否形成良好的实验能力的前提。只有学生端正了态度,才能自觉积极地学习实验技能。当前在部分学生中存在两种不好的学习态度:一是把实验当成“魔术”,以好看好玩为目的。结果是“实验手上做,现象眼边过”,名为一次实验,实际上只是看了一次热闹;二是观察、操作实验不认真、不细致,不讨论分析实验冲发生的现象和问题。针对这种情况,我和学生一道分析这些不正确的学习态度的危害性(如影响理论知识的接受,易发生实验事故等),同时对学生讲清各个实验的目的与要求,在此基础上制订必要的实验规程和纪律,并及时地督促检查,使学生逐步养成好的习惯。
First, grasp the attitude Students’ attitude towards the experiment is a prerequisite for the formation of good experimental ability. Only when the students correct their attitude can they consciously and actively learn experimental skills. At present, there are two kinds of bad learning attitudes among some students. The first is to use the experiment as “magic” and aim at good fun. The result is that “the experiment is done on the hand and the phenomenon is on the side of the eye.” It is called an experiment. It actually only saw the excitement; the second is that the observation and operation experiments are not serious and detailed, and they do not discuss the phenomena and problems of the analysis and experimentation. In response to this situation, I and students together analyze the harmfulness of these incorrect learning attitudes (such as the acceptance of theoretical knowledge, prone to experimental accidents, etc.), and at the same time explain to students the purpose and requirements of each experiment, based on this Formulate necessary experimental procedures and disciplines, and promptly supervise and inspect, so that students gradually develop good habits.
