必修1的核心内容是力与运动的关系,教材分了三个模块展开讲授。在运动的部分,学生学会了如何分析运动过程;在力的部分,学生又学会了受力分析;最后在处理力与运动的关系上,学生可以有效应用牛顿运动定律分析实际问题。本课牛顿第三定律讲述了相互作用力的规律,可以有效辅助研究问题,学生能合理选择研究对象而高效解决实际问题。牛顿第三定律是必修1教材第四章第5节内容,这是一节概念规律课。如果直接给出概念,将会枯燥乏味,因而本课采用实验探究的教学方法,提高学生的参与度,激发了学生的学习兴趣,更好地落实三维教学目标。 The core content of Compulsory 1 is the relationship between force and sports. The textbook is taught in three modules. In the part of sports, students learn how to analyze the process of exercise; in the part of force, students learn force analysis; in the end, in dealing with the relationship between force and sports, students can effectively apply Newton’s laws of motion to analyze practical problems. The Newton’s third law in this class tells the law of interaction, which can effectively assist research problems. Students can reasonably select research objects and effectively solve practical problems. Newton’s third law is the fourth chapter of Section 5 of the compulsory teaching material. This is a section of the concept law. If the concept is given directly, it will be boring, so this lesson adopts the teaching method of experimental inquiry to improve students’ participation, inspire students’ interest in learning, and better implement the three-dimensional teaching goal.
