中学化学演示实验“六忌”

＂Six Avoids＂ in High School Chemistry Demonstration Experiment

演示实验作为中学化学实验教学的范例。无疑不能露出半点破绽。为了达到这一目的，笔者从一忌不用仪器。以说代做；二忌盲目演示，不做说明；三忌只管自己，忘了学生；四忌只做实验，不管思维；五忌随心所欲，不合规范；六忌准备不足，实验失败等六个方面阐述了中学化学演示实验的注意事项。

Demonstration experiment as an example of the teaching of high school chemistry experiment, no doubt can not reveal the slightest flaw. In order to achieve this goal, I do not have the instrument from a bogey to generation to do; two, bogey blind demonstrations, not to explain; three, bogey just forget students; four, bogey only experiment, regardless of thinking; Five, Note arbitrary sub-specification; six, avoid ill-prepared, six aspects of the experiment fails, the Notes of a high school chemistry demonstration experiments.
