一、解析学生数学答题的错误1.审题能力不强,导致“拿起题来就做”先例举两道错误率极高又极容易的两题:例1,一条绳长9/10m,第一次剪去它的1/2,第二次剪去它的1/4,还剩多少?据本班38人调查统计:近68%的同学会这样列式:9/10-1/2-1/4。例2,一条公路长60m,已修了3/4m,还剩下多少米?这道题我区近800名学生的完全统计45.3%的同学这样 First, the analysis of mathematical errors in math problems 1. Scrutiny ability is not strong, leading to “take the title to do ” precedent cited two extremely high error rate and very easy question: Example 1, a rope length 9 / 10m , The first cut its 1/2, the second cut its 1/4, what is left? According to the survey of 38 people in this class: nearly 68% of students will be such a column: 9 / 10-1 / 2-1 / 4. Example 2, a road length 60m, has been repaired 3 / 4m, how many meters left? This question my area nearly 800 students complete statistics 45.3% of students so
