一、分析错因,避免重犯1.计算错误.由于考试心理紧张、计算器的数据(编程错误)、马虎、书写不规范等原因造成计算结果错误,这些是典型的“冤大头”.对此类错误题的分析,其意义不在于让学生纠正原题,而是让学生更多地意识到自己常常犯的错,如作业习惯不好等,然后将改正措施落实到平时的作业等练习中.如有的同学,在选择题中,会熟练地运用公式求三角形的面积;但一到综合题中,和其他几个步骤一混起来,就容易将前面的1/2忘掉,所求三角形面积凭空扩大了一倍!而犯此类错
First, the analysis of the wrong reasons, to avoid repeat 1. Calculation error. Due to the examination of psychological stress, the calculator data (programming error) sloppy writing is not standardized and other reasons caused the calculation error, these are typical The analysis of such errors, the significance is not to allow students to correct the original title, but to make students more aware of their mistakes often made, such as poor operating habits, etc., and then the corrective measures to practice such as peacetime exercises In the case of some students, in the multiple-choice questions, they will skillfully use the formula to find the area of the triangle. However, when it comes to a comprehensive question and mixed with several other steps, it is easy to forget the previous one and ask Triangle area out of thin air doubling! And make such mistakes
