在化学教学大綱(草案)上明確地指出:“化学是一門以实驗为根据的科学”。所以在教学过程中应該按照大綱的規定,作好演示实驗,並指導学生進行实驗。通过学習苏联先進經驗,知道在苏联中等学校化学教学中通行着一种“边講边做实驗”的教学法。这种方法的特點是:在一節課内,教師不但要講解、做演示实驗,同時还要指導学生進行实驗。这就能增强教学的直观性,使学生在明確的感性認識的基礎上,獲得理性的知識,並能初步地培养学生实驗操作的技能。这对改進教学、提高教学質量是有着很大作用的。因此,我們在初步領会了这种教学法的精神以後,也開始試行了这种教学方法。因为这是一种新的教学方法,加上我們沒有經驗,在試行过程中曾經遇到了一些困难。
On the chemistry syllabus (draft) clearly states: “Chemistry is an experiment-based science.” Therefore, in the teaching process should be in accordance with the provisions of the outline, to demonstrate experiments, and guide students to experiment. By studying advanced Soviet experience, we know that there is a teaching method of “experimenting while teaching” in chemistry teaching in Soviet secondary schools. This method is characterized by: In a class, teachers not only to explain, do demonstration experiments, but also guide students to experiment. This will enhance the intuitive teaching, enable students to acquire a rational knowledge based on a clear sense of perceptual knowledge, and can initially develop students’ skills in experimental operation. This is to improve teaching, improve teaching quality has a great role. Therefore, after tentatively understanding the spirit of this pedagogical method, we have also tried out this teaching method. Because this is a new teaching method, plus we have no experience, we encountered some difficulties during the pilot process.
