牛顿第一运动定律是初中物理的重点,也是难点。教学时应在“破”和“立”上下功夫.即破亚里士多德错误观点,立伽利略正确观点及牛顿第一运动定律。破是教学难点,立是重点。做法如下.一、欲抑先扬设“圈套”诱学生上当学生对客体的感知是以个体的生活经验为中心 Newton’s first law of motion is the focus and difficulty of junior high school physics. When teaching, you should work hard on “break” and “stand”. That is to say, break Aristotle’s erroneous view, correct Galileo’s point of view, and Newton’s first law of motion. Breaking is the difficulty of teaching and standing is the key point. Practices are as follows. First, desire to suppress the first “trap” to attract students to confess that students’ perception of the object is based on the individual’s life experience.
