初中化学是学生系统学习化学知识的初始,观察能力尚待开发。所以应在化学实验的教学中,培养学生的观察兴趣、科学的观察方法和实事求是的科学态度,逐步形成良好的观察能力。一、培养学生的观察兴趣教材中的许多实验现象对学生来说是相当有趣的,如镁带的燃烧、白磷的自燃、NaOH Junior high school chemistry is the initial stage for students to systematically study chemical knowledge, and their observation ability remains to be developed. Therefore, in the teaching of chemistry experiments, we should cultivate students’ interest in observation, scientific observation methods and scientific attitude of seeking truth from facts, and gradually form a good observation ability. I. Fostering students’ interest in observations Many experimental phenomena in textbooks are quite interesting for students, such as the burning of magnesium belts, the spontaneous combustion of white phosphorus, and NaOH.
