化学教学离不开实验教学,有教师的演示实验、学生的学生实验等。但实验教学中的安全问题又成为了我们的一个大问题。因而注重化学实验中的安全问题就显得尤为重要。消除实验事故隐患,培养学生安全意识是一名化学教学工作者义不容辞的责任。化学实验是化学教学的一种最有效的教学形式,也是学生最感兴趣内容。但有一部分学生在做化学实验时往往不是去了解实验目的、去注意实验步骤,而是只关注实验现象。因而一进入实验室 Chemistry teaching can not be separated from experimental teaching, teacher demonstration experiments, students’ experiments and so on. However, the safety issue in experimental teaching has become a big problem for us. So pay attention to the safety of chemical experiments is particularly important. Eliminating the hidden dangers of experimental accidents, cultivating students’ safety awareness is a bounden duty of a chemistry teaching worker. Chemistry experiment is one of the most effective teaching methods in chemistry teaching, which is also the most interesting content for students. However, some students do chemical experiments often not to understand the purpose of the experiment, to pay attention to the experimental steps, but only focus on experimental phenomena. Thus entered the laboratory
