A Study On Classification And Statistical Analysis Of Chemical Open Questions In College Entrance Examination

With the deepening of the curriculum reform, more attention is paid to the quality education and innovation education.As exercise students’ innovative, more attention is paid to the open chemistry questions.It not only applied in the teaching, also appeared in the college entrance examination questions. not only used to test students the basic knowledge of master degree, also used to detect the innovation ability of students, students’ emotion and values, It is the seal of the past problems that cannot be replaced, Open the topic in recent years, more and more be taken seriously, But the study of open chemistry questions started later, The study of open the college entrance examination chemistry questions are much rarer, And in the past five years,the economic developrapidly,therequirement of Talent also change rapidly, Chemical curriculum reform is also changing, The trends in the chemistry of the college entrance examination are also changing, So, It is necessary to analyze the statistical analysis of the chemical open questions in the college entrance examination. Through the classification of chemical college entrance examination questions, let the students grasp the characteristics of different types of open questions, and the entrance of open questions in recent years,To improve the accuracy of the open entrance examination.So this thesis collected from 2006 to 2015, nearly10 years of the national college entrance examination chemistry exam, a total of 136 sets,Among them 103 sets for the science involved in the synthesis of chemical knowledge,The rest of the 33 sets are single chemical papers. This 136 papers of which, the volume is 23 sets,Other papers are local autonomy proposition. Through the statistical analysis of 136 sets of the examination, find out the law of the open questions. To help teachers better understand the university entrance exam the change of the open, better implementation of teaching, so as to prepare students for the college entrance examination.This thesis is divided into Five parts:The first part of this paper is Theoretical basis,The theory of constructivism and the theory of SOLO classification can provide a theoretical support for the classification and statistical analysis of chemical open questions in college entrance examination.The second part is an overview of the theory of the open-ended questions,Through the open concept, types, methods, types, characteristics, functions are clearly defined and provide the theoretical basis behind the college entrance examination chemistry open problems of classification and statistical analysis.The Third part of this paper is Statistical analysis, Through statistical analysis of the college entrance examination papers in different regions in the past few years, the law and dynamic trend can be found to be effective for the candidates who are about to take part in the college entrance examination.The Fourth part of this paper isClassification study, Through the classification of college entrance examination of chemistry open-ended problem research, solution analysis of various types of chemistry open-ended problem, analysis technique of the various types of features and doing exercises, for students of different levels, make it as much as possible to achieve high grades.The Fifth is divided into advice, through the analysis of the classification and statistics of the open questions of the college entrance examination, the characteristics of all kinds of open questions and the methods of solving the problems are summarized. Some suggestions are put forward for the students and teachers.
