【背景介绍】随着新课程标准的实施,数学教学应该更多地关注每个学生的情感。健康与富有活力的学习活动以及相互尊重的学习氛围非常有利于学生非智力与智力因素协调发展,有利于健康人格的形成。【案例描述】我在一次教学过程中,创设了这样的情景:在班上选择了全班公认数学最优秀的和最差的进行口算比赛,两组题目如下:1:2.5×32 7.8+6.5+2.2 15×(4-0.5)2:100-63 48+39 17×40。比 【Background】 With the implementation of the new curriculum standards, mathematics teaching should pay more attention to each student’s emotions. Healthy and energetic learning activities and mutual respect for the learning environment is conducive to the coordinated development of students non-intelligence and intellectual factors, is conducive to the formation of healthy personality. 【Case Description】 In a teaching process, I created such a scenario: I chose the best and worst mathematics math class in my class, and the two groups are as follows: 1: 2.5 × 32 7.8 + 6.5 +2.2 15 × (4-0.5) 2: 100-63 48 + 39 17 × 40. ratio
