为了提高实验教学的效果,除了加强课堂教学中的化学实验外,课外活动中的化学实验也必须予以重视。一、加强化学知识,课外实验活动在课外活动中,做一些结合课堂上学到的知识,并且联系实际生活或工农业生产知识的实验,将会使学生对学习化学产生浓厚的兴趣,这是调动学生主观能动性,巩固提高智能的有力措施。例如,让初学化学的人在课外观察蜡烛的火焰,并记录观察到的现象,一般的学生只能观察到几种现象,但是
In order to improve the effectiveness of experimental teaching, in addition to strengthening the chemical experiments in classroom teaching, extracurricular chemical experiments must also be taken seriously. First, to strengthen the chemical knowledge, extracurricular experimental activities In extracurricular activities, to do some combination of knowledge learned in the classroom, and practical experience in life or work of agricultural production knowledge experiment, will enable students to have a strong interest in learning chemistry, which is to mobilize Subjective initiative of students to consolidate the smart measures to improve intelligence. For example, letting a beginner chemistry observe the flame of a candle outside the class and record the observed phenomena. The average student can observe only a few phenomena, but
