初中化学实验教学可以激发学生学习化学的兴趣,帮助学生形成化学概念,获得化学知识和实验技能,培养观察和实验能力,还有助于培养实事求是、严肃认真的科学态度和科学的学习方法。“充分认识实验教学在化学教学中的地位和作用,切实采取措施加强实验教学,是提高化学教学质量的重要环节。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的。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 Junior high school chemistry experiment teaching can arouse students’ interest in learning chemistry, help students to form chemical concepts, gain chemical knowledge and experimental skills, develop observation and experiment skills, and help develop realistic and serious scientific attitudes and scientific learning methods. ”Fully understanding the status and role of experimental teaching in chemistry teaching and practically taking measures to strengthen experimental teaching is an important step to improve the quality of chemistry teaching.“ Junior chemistry teaching is the enlightenment phase of chemistry education. Junior high school students are young, curious, Their motivation to learn chemistry is often based on curiosity and interest.5 The primary task of chemistry experiment teaching is to stimulate students’ interest in learning chemistry and to make such ”transient" interests
