实验习题课是化学教学的重要组成部分。它对于巩固知识,培养学生的实验技能,提高化学课的教学质量是十分有益的。因此,我们以竞赛法代替传统的练习法,进行实验习题课教学。本文谈谈我们的具体做法和体会。一、推选赛手和评委将一个班的学生分成4个小组,每组推选两名选手,现场演示讲解。全班选出5名化学成绩优秀的学生作为评委,现场打分。其余学生观摩、质疑和评议。二、精选赛题和预习所精选的实验习题要有启发性,能起到检查、充实、巩固和提 Experimental class is an important part of chemistry teaching. It is very useful for consolidating knowledge, cultivating students’ experimental skills, and improving the teaching quality of chemistry classes. Therefore, we use the competition method instead of the traditional practice method to teach experimental exercises. This article talks about our specific practices and experiences. First, the selection of players and judges will be divided into four groups of students in a class, each group selected two players, live presentations to explain. Five excellent students with excellent chemistry scores were selected as judges in the class and scored on-site. The remaining students observe, question and comment. Second, the selection of contest questions and preview of selected experimental exercises should be instructive, can play a check, enrich, consolidate and mention
