The Analysis And Review Strategy Research On The Questions Of "Chemical Substances Around" In Tianjin 2012-2018 Middle School Entrance Examination

Based on Bloom's target classification theory,constructivist theory,and humanism theory,this paper draws on the SEC model(two-dimensional matrix method)proposed by American scholar Porter in 2002,using literature analysis,content analysis and statistics.From the two dimensions of content theme and cognition level,the law quantitatively examines the consistency of the “Chemical Substance” test of Tianjin middle school entrance examination Chemical in 2012—2018 with the new curriculum standards.In terms of content topics,according to the 2011 new curriculum standards,the classification of chemical content in middle schools,the theme of “chemical substances around” is coded,the content dimension analysis table is produced,and the test questions are compared with the content dimension analysis tables.And draw conclusions;in terms of cognitive level,according to the requirements of the new curriculum standard and Bloom's target classification theory,the cognitive dimensions of the specific content under each secondary theme are counted,and the knowledge points and cognitions of the test questions are examined.The dimension table is used for statistics.Using the porter consistency formula,the consistency coefficient P for each year is calculated.In this study,the consistency coefficients of the "Chemical Substance" test and the curriculum standards of Tianjin middle school entrance examination Chemical in 2012—2018 are P = 0.743,0.857,0.843,0.805,0.842,0.837,0.798,respectively,according to the baud coefficient.According to the characteristics,in the past seven years,the "chemical substances around" test and the "new course standard" in the Tianjin senior high school entrance examination paper have a high consistency in the cognitive dimension.The study found that the scores of the "chemical substances around us" test in Tianjin's senior high school chemistry are relatively high.Theexamination is mainly based on basic knowledge,and there are many secondary topics in the air around us.Finally,the relevant teaching suggestions for the “chemical substances around us” of Tianjin University Entrance Examination Chemistry are proposed:(1)Strengthen the teaching of basic knowledge and basic skills according to the new curriculum standards;(2)Emphasize the teaching of basic concepts and principles,and attach importance to knowledge.Itinerary and understanding;(3)Teaching on the curriculum should pay attention to the relationship between chemical knowledge and real life;(4)Improve experimental teaching and cultivate students' basic skills and basic abilities;(5)Make full use of teaching materials and organize special review;(6)Effective simulation training,summarizing the wrong questions.I hope that the above research can provide some reference information for the teaching and review of Tianjin educators.
