笔者曾听过一节“力的分解”公开课,课后与其他教师进行了认真的讨论、分析、研究,觉得这节课体现了新课程的教学理念,突出了物理学科的课程目标,落实了在教师指导下的自主学习、合作学习、探究学习的学习策略,合理解决了本节课所需的初、高中知识的衔接问题,通过问题引导基本完成了本节课的教学目标,教学效果良好。现摘录部分教学片段和大家分享。一、教学目标(一)知识与技能1.通过实例知道什么是力的分解,理解力的分解也遵循平行四边形定则。2.初步学会按力的实际作用效果来分解力。3.学会用作图法求一个力的两个分力;初步学会
I have heard a section of “force decomposition” open class, after class and other teachers conducted a serious discussion, analysis, research, think this class embodies the new curriculum teaching philosophy, highlighting the curriculum objectives of physics , Implemented the learning strategies of autonomous learning, cooperative learning and inquiry learning under the guidance of teachers, reasonably solved the connection problems of primary and senior high school knowledge required by this lesson, basically completed the teaching objectives of this lesson through question guidance, Teaching effect is good. Now excerpt part of the teaching clips and share with you. First, the teaching objectives (A) knowledge and skills 1. Through examples to know what is the decomposition of the power, decomposition of understanding also follow the parallelogram rules. 2. The initial learning by the actual effect of force to break down. 3. Learn to use the two components of a force for the map method; preliminary learning
