初中化学教学是化学教育的启蒙阶段。初中学生年龄小,好奇心强,他们学习化学的动机往往是以满足好奇心和感兴趣为主。化学实验教学的首要任务是如何激发学生对学习化学的兴趣,并使这种“短暂”的兴趣能够稳定地保持并得以发展,从而提高他们学习化学的主动性和积极性。 Junior chemistry teaching is the initiation stage of chemistry education. Junior high school students are young and curious. Their motivation for learning chemistry is often to satisfy curiosity and interest. The primary task of chemistry experiment teaching is how to stimulate students’ interest in learning chemistry, and to make this “short-lived” interest stable and develop, so as to improve their initiative and enthusiasm for learning chemistry.
