在学习等值线时,教师往往从整体着手找规律,容易忽略细节问题,往往因为这些细节问题,影响了整体的教学效果。教师应从细微处入手,注意等值线的画法,研究等值线与等值线之间的关系,让学生学会等值线、等温线和等降水量的判读,提高学生的学习效果。一、等值线的画法要正确判断等值线图,必须明确理解等值线的画出方法。懂得等值线的画法有利于学生形成空间思维。对于等值 When learning contours, teachers often start looking for patterns from the whole, and it is easy to ignore the details. Often these details affect the overall teaching effect. Teachers should start from the subtleties, pay attention to the contour drawing method, study the relationship between contours and contours, and allow students to learn the interpretation of isolines, isotherms, and other precipitation, so as to improve students’ learning effects. First, the contour line drawing method to correctly determine the contour map, we must clearly understand the contour line drawing method. Understanding the contour drawing method helps students form spatial thinking. For equivalent
