在物理教材中,力学知识占有非常大的比重,也是历年高考的重点内容。力学知识中,摩擦力一直是教学难点,学生在学习过程中经常会遇到障碍。在课堂上,教师应当采用多样化的教学方式,逐步培养学生的学习兴趣与自学能力。作为物理教师,应当以新课改的要求,充分把握物理教材资源,改变传统的教学观念,认识到授课不仅仅是给学生传授知识,还应 In physics textbooks, mechanical knowledge holds a very large proportion, but also the key content of the college entrance examination over the years. In mechanical knowledge, friction has always been a difficult teaching point, and students often encounter obstacles in their learning. In the classroom, teachers should adopt a variety of teaching methods, and gradually develop their interest in learning and self-learning ability. As a physics teacher, we should fully grasp the resources of physics teaching materials and change the traditional teaching concepts with the requirements of the new curriculum reform. We should recognize that teaching is not only for imparting knowledge to students, but also
