数学学习能力是一个人立足于社会的基本能力,也是学生的基本素养,培养学生的学习能力是教育的根本目的。而近几年,笔者发现学生学习数学的能力呈下降趋势,学生似乎越来越不会学习数学。一、现象描述在上初一数学第二学期第7章“平面图形的认识(二)”的复习课中,为了提升训练难度,我选了这样一个题目:如图1,在六边形ABCDEF中,AF//CD,∠A=140°,∠C=165°,求∠B的度数。
Mathematical learning ability is a basic ability of a person based on the society, but also the basic quality of students, to develop students’ learning ability is the fundamental purpose of education. In recent years, however, I have found that students’ ability to learn math has been declining. Students seem to learn mathematics more and more. First, the phenomenon described in the first semester of mathematics seventh semester “plane graphics understanding (two) ” in the review class, in order to enhance the training difficulty, I chose such a topic: Figure 1, on the six sides Shape ABCDEF, AF // CD, ∠A = 140 °, ∠C = 165 °, find the degree of ∠B.
