中学物理里单摆的教学中回复力的分析一直是教师教学的难点,学生学习的疑点,用几何画板这个高中生熟悉而又信任的工具,以直观、定量的呈现回复力的大小、方向的相关参数的形式来突破难点,是一条非常有效和值得提倡的途径。
The analysis of resilience in the teaching of pendulum in middle school physics has always been the difficulty of teachers ’teaching and the suspicion of students’ learning. With the geometric drawing board, a familiar and trusted tool for senior high school students, the resilience and direction of visual acuity Relevant parameters in the form of breakthrough difficulties, is a very effective and worthy of promotion.
