Research On The New College Entrance Examination Questions Setting System From The Perspective Of "key Competencies-based"

The test question research ability is one of the basic research abilities of middle school chemistry teachers,which affects teaching design,teaching implementation and teaching effect evaluation.Doing a good job of research on propositions will help teachers deeply understand the key competencies of chemistry and the key abilities of students that need to be formed.Really understand the question of "why,what and how to test".This research uses the literature method,text analysis method and statistical analysis method.Based on the analysis of the key competencies and chemistry proposition research status at home and abroad,the 2018-2020 college entrance examination chemistry papers are used to carry out the distribution of knowledge points,problem situations and the key competencies of chemistry.Level statistics and analysis,explore the rules of college entrance examination propositions and key competencies investigation trends from the perspective of "key competencies-based",summarize and put forward the predeterminative principles of the new college entrance examination chemistry original test questions,and on this basis,draw up a set of new college entrance examination original test questions.This research consists of six parts: The first part is the introduction.The research background,purpose and significance of the thesis are introduced in this part in detail,summarizes the current research status of key competencies and the analysis of test questions based on key competencies,and the destiny system at home and abroad.The research ideas and methods are introduced.The second part defines related concepts and introduces the theoretical basis of the research,expounding the understanding of the connotation of "the key competencies of chemistry",and laying the foundation for constructing the analysis framework of the test questions.The third part is the analysis of chemistry test questions in the college entrance examination from the perspective of "key competencies-based".First,build a test question analysis framework,and systematically sort out and analyze the chemistry test questions in the past three years based on this,and extract the proposition characteristics of the chemistry test questions in the college entrance examination.The proposition provides the basis.The fourth part studies the proposition of chemistry test questions from the perspective of "key competencies-based",extracts the proposition framework and procedures,and summarizes the proposition principles and strategies.In the fifth part,under the guidance of the above-mentioned proposition theory,a set of original propositions and analysis explanations for the simulation test questions of the college entrance examination are carried out.The sixth part is research conclusions and reflections,summarizing the evaluation model of the test questions,the horizontal and vertical comparison research results of the national papers in the past three years,the proposition theory model and the drafting explanation of this set of chemistry simulation test questions for the college entrance examination.At the same time,it reflects on the deficiencies of the research."Key competencies-based" learning evaluation needs to use "key competencies-based" test questions as the carrier.Based on the theoretical basis of chemistry key competencies,this paper constructs a test question evaluation framework,and analyzes the chemistry test questions of the national college entrance examination papers in the past three years from the dimensions of chemistry knowledge,problem situation,key competencies and level of chemistry.On this basis,the framework,principles,procedures and strategies of the proposition are summarized,and the proposition of the original chemistry test questions under the "key competencies-based" perspective is researched,and a set of simulated original test questions for the college entrance examination are completely designated as examples.It provides methods and ideas for the analysis of test questions and the preparation of original test questions,and explores the key competencies of chemistry.
