在教学活动中,测量物体的高度或测量两点相对于测量地的夹角是我们经常遇到的问题,“教学简易测高(角)仪”较好地解决了这个教学问题。它可用于数学、地理和物理等学科的课堂教学和课外实践活动。在使用过程中,通过理论联系实际,加深学生对锐角三角函数、太阳高度角、小孔成像等数学、地理和物理等概念的理解。该器材结构简单,使用方便,适用于多个学科,具有较强的实用性,是老师和学生教学与实践活动的好帮手。 In teaching activities, measuring the height of an object or measuring the angle between two points relative to the measured point is a problem that we often encounter. The simple teaching height gauge solves this teaching problem. It can be used for classroom teaching and extracurricular activities in mathematics, geography and physics. During the course of using, we should deepen students’ understanding of the concepts of math, geography and physics by means of acute trigonometrical functions, solar elevation angles and pinhole imaging by linking theory with practice. The utility model has the advantages of simple structure, convenient use, suitability for multiple subjects, strong practicability, good help for teachers and students in teaching and practice activities.
