化学是一门以实验为基础的科学,化学实验正是进行科学探究的主要方式,“让学生有更多的机会主动地体验探究过程”(摘自全日制义务教育《化学课程标准》)。实验不但能激发学生的学习兴趣,还能让学生巩固旧知识和获得新知识;不但能让学生学会科学的学习方法,还能提高科学探究的能力。因此,在化学教学中教师要选好实验,用好实验,做好实验,充分发挥实验的探究功能。 Chemistry is an experiment-based science, and chemical experiments are the main way to do scientific inquiry. “It gives students more opportunities to actively experience the inquiry process” (taken from full-time compulsory education chemistry curriculum standard) . Not only can the experiment stimulate students’ interest in learning, but also enable students to consolidate the old knowledge and obtain new knowledge; not only enable students to learn scientific learning methods, but also improve the ability of scientific inquiry. Therefore, in chemistry teaching, teachers should choose an experiment, make good use of experiments, do experiments, and give full play to the exploratory function of the experiment.
