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,学习化学的动机往往以满足好奇心和感兴趣为主。化学实验教学的首要任务是激发学生学习化学的兴趣,并使这种“短暂”的兴趣稳定地保持并得以发展,从而充分调动他们学习化学的主动性和积极性。 Junior high school chemistry teaching is the enlightenment phase of chemistry education. Junior high school students are very young and curious. Their motivation to learn chemistry is often based on curiosity and interest. The primary task of chemistry experiment teaching is to stimulate students’ interest in chemistry and to maintain and develop this “short-lived” interest so as to fully mobilize their initiative and enthusiasm to learn chemistry.
