物理学是以实验为基础的自然科学。实验是学习物理的重要内容,又是激发学生的学习兴趣、培养学生的动手能力的重要教学资源,对提高学生综合素质发挥着重要的作用。演示实验教学是物理实验教学的重要组成部分,是落实物理课程目标、全面提高学生科学素养的重要途径。初中物理课堂因演示实验而会更加精彩。一、演示实验有利于激发学习兴趣,吸引学生注意力心理学研究表明:学生学习情绪不稳定,注意力不集中是影响学生学习效果的重要因素之一。教师采用演示实验教学可以给 Physics is based on experimental science. Experiment is an important part of learning physics, and it is also an important teaching resource that stimulates students ’interest in learning and cultivates students’ practical ability. It plays an important role in improving the overall quality of students. Demonstration experiment teaching is an important part of physics experiment teaching, and it is an important way to fulfill the goal of physics curriculum and comprehensively improve students’ scientific accomplishment. Junior Physics Classroom will be more exciting due to demonstration experiments. First, the demonstration experiment is conducive to stimulate interest in learning to attract students’ attention Psychology Research shows that: students learn emotional instability, lack of concentration is one of the important factors that affect the learning effect of students. Teachers using experimental teaching can give
