010年温州市高三（Wenzhou city high 3） The quality analysis of the test chemistry test of the high three one model in wenzhou city in 2010 The second review of 2010 review preparation advice Zheng daxi, middle school of wenzhou, zhejiang province The quality analysis of the test chemistry test paper At the beginning of the New Year, senior three students took the first adaptive test in wenzhou. In this paper, a sampling analysis of the test results of the students participating in the science comprehensive ability (chemical part) of wenzhou middle school students is 100 people. The difficulty of choosing the problem is 0.86, the difficulty of choice is 0.67, the total difficulty is 0.75, the overall difficulty is relatively moderate, compared to last year the city is slightly more difficult. 1. Select the topic section qid A (number of people) B (number of people) C (number of people) D (answer number) The difficulty coefficient 7 0 8 3 89 0.89 8 4 60 22 14 0.60 9 0 4 91 5 0.91 10 89 3 5 3 0.89 11 0 10 90 0 0.90 12 one 96 0 3 0.96 13 4 6 87 3 0.87 The total difficulty of the choice is 0.86, and the overall difficulty is small. The total number of students was 39 percent, the wrong one was 36 percent, the wrong two were 16 percent, the wrong three were 6 percent, and the wrong four were 3 percent. The most easy problem is number 12, with a difficulty coefficient of 0.96, which is an electrochemical problem with a new background of knowledge. Due to the low point of knowledge, the distinction of this topic is very small. Problem is the nature of magnesium, aluminum and compounds 13 and computational problems, involved in the precipitation of calculation is more difficult, the problem can test students mastery of magnesium, aluminum and the properties of the compound, and can test students ability of calculation, is a good topic, but because of the set C answer wrong too obvious, thus greatly reduce the difficulty of the subject, the difficulty coefficient is 0.87.
