解题教学是课程教学的重要组成部分,解题是一线教师和学生关注的焦点之一,随着新课改的不断深化,物理试题越来越体现学生应用能力的考查.在物理考试大纲中,明确要求学生具备运用数学知识解决物理问题的能力,这也提醒物理教师在课堂教学中注重引导学生灵活运用数学工具处理物理问题.在高中物理力学极值问题的求解中,相似三角形是一种重要的解决问题的方法,它实现了抽象问题的形象化、直 Problem-solving teaching is an important part of curriculum teaching. Solving questions is one of the focuses of front-line teachers and students. With the continuous deepening of new curriculum reforms, physical examination questions increasingly reflect the examination of students’ application ability. In the physics exam outline It clearly requires that students have the ability to use mathematics knowledge to solve physics problems. This also reminds physics teachers to focus on guiding students to use mathematical tools flexibly to deal with physics problems in classroom teaching. In solving high school physics and mechanics extremum problems, similar triangles are a kind of An important solution to the problem, it realizes the visualization of abstract problems, straightforward
