物理实验教学是激发学生兴趣,提高教学质量的重要方法,而自制教具具有配备仪器不可替代的优点。平抛运动是高中物理中的一个重要知识点,通过实验获得轨迹图象并利用其分析解答相关问题是学好该知识点的关键,而人教版高中物理必修2教材实验装置却存在一定的不足。自制一款“持续平抛运动轨迹实验装置”应用于教学活动之中,不但能克服教材实验装置的不足,而且能激发学生的兴趣,达到快速出图和效果明显的目标。 Physics experiment teaching is to stimulate students’ interest and improve the quality of teaching an important method, and self-made teaching aids equipped with the equipment irreplaceable advantages. Flat throwing throwing is an important knowledge point in high school physics. It is the key to learning this track by taking the trajectory image through experiments and analyzing and answering relevant questions. However, there are some deficiencies in the PEP teaching material . Self-made “continuous flat throw trajectory experimental device ” used in teaching activities, not only to overcome the shortcomings of experimental teaching device, but also to stimulate student interest, to achieve the goal of rapid drawing and the effect is obvious.
