在中学化学教学中,实验占有重要地位,实验的主要任务是:引导学生仔细观察实验现象,直接获得化学感性认识;巩固并加深对所学理论知识的理解;训练学生正确掌握化学实验的基本方法和基本技能,提高分析问题和解决问题的能力。真正使学生在实验教学中达到以上目的,除化学教师教育指导外,化学实验员也起着决定性的作用。因此,当好中学化学实验员是很不容易的。
In the middle school chemistry teaching, the experiment occupies an important position. The main tasks of the experiment are: to guide the students to observe the experimental phenomena carefully, to directly obtain the sensibility of chemistry; to consolidate and deepen the understanding of the theoretical knowledge; to train the students to master the basic method of chemical experiment correctly. And basic skills to improve the ability to analyze problems and solve problems. The students are truly enabled to achieve the above objectives in experimental teaching. In addition to the chemical teacher education instruction, the chemistry experimenter also plays a decisive role. Therefore, it is not easy to be a chemistry lab technician in a good middle school.
