恢复高考三十多年来,高考数学试卷从开始的一年一套,到现在的一年二十多套,题量越来越多,其中有40%是中档题.如果用难度系数来分类,难度系数在0.85~1之间的是简单题,在0~0.3之间的是难题,中档题则介于简单题和难题之间.中档题梯度明显区分度比较高,能充分满足考试的选拔功能,所以中档题的好差直接关系到整份高考试卷的质量.本文就对历年的一些高考题进行分析,并就高考数学
Three decades to resume college entrance examination, college entrance examination mathematics papers from the beginning of a year, until the current year more than 20 sets, more and more questions, of which 40% are mid-range questions. If you use the degree of difficulty to classify , The difficulty coefficient between 0.85 ~ 1 is a simple question, in the 0 ~ 0.3 is the problem between the mid-range problem is between simple questions and puzzles mid-range title gradient significantly higher degree of differentiation, can fully meet the test Selection function, so the poor mid-range test is directly related to the quality of the entire college entrance examination papers.This paper analyzes some of the college entrance examination papers over the years,
