《义务教育物理课程标准》注重科学探究,要求学生通过各种探究活动亲自得出结论,并亲身参与、体验知识获得的过程,构建起新的对自然的认识,在此基础之上,学生对于科学知识的探索兴趣增强,学习科学知识的态度变得脚踏实地,并且使学生在已掌握知识的基础上进行新的探索创新,在此期间可以不断地提高学生的能力。初二物理是学生学习的一个崭新起点,这就需要教师在教学过程激发学生的学习兴趣,帮助学生主动获取知识,强调知识的探究过程,不断实现教学效率的提升。 Compulsory education physics curriculum standards focus on scientific inquiry, require students to personally come to conclusions through various inquiry activities, and personally participate in, experience the process of knowledge acquisition, build a new understanding of nature, on this basis, the students for The interest in exploration of scientific knowledge is enhanced, the attitude of studying scientific knowledge becomes down-to-earth, and students are allowed to carry out new exploration and innovation based on the knowledge they already possess. During this period, the ability of students can be constantly improved. The first two physics is a new starting point for student learning, which requires teachers in the teaching process to stimulate student interest in learning to help students take the initiative to acquire knowledge, emphasize the process of knowledge of the inquiry, and constantly improve teaching efficiency.
