一、指导思想及课前设计高中物理第一册(必修)“牛顿第一定律”一节,属初、高中知识的结合部。学生在初中学习中,已经了解了牛顿第一定律的基本内容。如何以初中知识为生长点、以教材内容为线索,展开科学方法教育与思维能力培养是本课教学活动的主要目标。故教学的侧重点应放在理解伽利略对“运动物体不受外力作用会保持自己的速度不变”论断的研究、思考、推理过程,学习科学研究中常用的理想实验方法。为此本节教学采用讨论式:教师列出讲演提纲,在阅读教材的基础上,请一位学生率先演讲,引发学生的问题,展开答辩与讨论。教师在其间适当
First, the guiding ideology and pre-class design High School Physics Book One (required) “Newton’s first law” section, is a combination of primary and high school knowledge. Students in junior high school have already understood the basic content of Newton’s first law. How to use junior high school knowledge as a growing point and the content of teaching materials as a clue, to develop scientific methods of education and thinking ability training are the main objectives of the teaching activity. Therefore, the focus of the teaching should be on understanding Galileo’s research, thinking, and reasoning about the assertion that “a moving object will not change its speed without external force” and the ideal experimental method commonly used in learning scientific research. For this reason, the teaching in this section adopts a discussion type: the teacher lists the lecture outlines, and on the basis of reading the teaching materials, asks a student to give the first speech, triggers the student’s question, and initiates the defense and discussion. Teachers are appropriate
