Study On The Content Of The Question Sin-test On "The Mystery Of Material Composition" In The Middle Examination Chemistry In Shanxi Province In The Last Five Years

Based on constructivism theory and bloom education target classification theory as the foundation,this paper adopts the SEC model to analyze the question content of "the mystery of material composition" in the chemistry of shanxi high school entrance examination in the past five years from two aspects,namely content dimension analysis and cognitive dimension analysis.First: In terms of the content dimension,first according to the curriculum criteria of the "mystery of material composition" topic of content classification,I coded this topic,and then produced a content dimension analysis table,counted the number of topics content examinations and test question examination methods,and concluded that the total number of examinations on the subject of "the mystery of material composition" in the Shanxi middle school entrance examination in the past five years was not very high.The expression of "composition" and "particle-forming substance" are more likely to be examined.In the past five years,the examination of the "mysteries of material composition" has basically been based on written descriptions.Second: In terms of cognitive dimensions,I divided the cognitive dimensions into four categories,namely "know","knowledge","understanding" and "application",according to the cognitive dimension of the curriculum standard,the examination contents of the exam questions are calculated.Statistics found that the examination of "the mystery of material composition" mainly focused on the dimensions of "know" and "knowledge".In the past five years,the "knowledge" cognitive dimension of "particle-constituting matter" has been examined the most,and the "representation of matter composition" has been examined most in the "cognition" cognitive dimension.The "mystery of material composition" is rarely examined in the "understanding" dimension,and the "application" cognitive dimension is not.Finally,the consistency coefficient is calculated using the SEC mode.In this study,it is calculated that in the last five years,the consistency coefficient scored by the "mystery of material composition" questions and the curriculum standards in the middle of Shanxi Province was 0.723,0.777,0.45,0.699 and 0.49,with an average value of 0.628.It is shown that the test questions and the curriculum standards do not have significant consistency in cognitive dimensions.In the end,some teachers' teaching Suggestions and students' learning strategies are provided according to the research topic,I hope this paper is helpful to teachers and students in Shanxi Province.
