化学实验是认识物质,改造物质的重要手段,也是发展学生能力的重要一环。化学教师必须熟练地掌握化学实验的各种技能、技巧。为了做好中学化学实验,教师可在平时积累各方面的资料,其中之一,是逐步建立实验档案卡。实验档案卡的内容一般来说可包括:实验课题;配合教材内容;实验(演示)目的;仪器药品;实验操作步骤;反应条件及现象;实验成功关键和实验中可能出现的问题及解决办
Chemical experiments are an important means of understanding materials and transforming them, and they are also an important part of developing students’ abilities. Chemistry teachers must master the various skills and techniques of chemical experimentation. In order to do a good chemistry experiment in middle school, teachers can accumulate all kinds of information in peacetime. One of them is to gradually establish an experimental file card. The contents of the experiment file card can generally include: experimental topics; content of teaching materials; experiment (demonstration) purposes; equipment and drugs; experimental procedures; reaction conditions and phenomena; key to the success of the experiment and possible problems and solutions in the experiment.
