化学是一个以实验为基础的学科.在化学教学中,实验教学起着不可替代的作用.在新课程标准背景下,要求教师重视提高学生的自主探究能力和动手能力,在教学中要以学生为主体,培养学生的自主学习能力.家庭小实验就是在这样的背景下发展起来的.这种小实验,不仅能激发学生对化学的学习兴趣,还能培养学生的实验能力,进而引导学生自主探究.家庭小实验是学生对课堂知识的一种延伸方式,操作简便.在初中化学教学中,加入家庭 Chemistry is an experiment-based discipline .In chemistry teaching, experimental teaching plays an irreplaceable role.In the context of the new curriculum standards, teachers are required to attach importance to improve students’ ability of self-exploration and practical ability, in the teaching to students As the main body to develop students’ ability to learn independently.The small experiment is developed in this context.This small experiment, not only can stimulate students interest in chemistry, but also to develop the experimental ability of students, and then guide students to autonomy Explore. Small family experiment is an extension of the students knowledge of the classroom, easy to operate. In junior high school chemistry teaching, join the family
