Statistical Analysis And Study Of Test Preparation Strategies For Chemistry Calculation Questions In The College Entrance Examination

As an important way to select talents on a large scale in our country's colleges and universities,the college entrance examination is of great significance to the development of cutting-edge talents training,transmission and even the development of civilized society in China.College entrance examination chemical calculation test question sq.,comprehensive coverage,the basic knowledge of students master,logical thinking,problem-solving ability has higher requirements,often let students stand back.Therefore,in the course of the research of the high examination chemistry calculation questions,the exploration of the characteristics of propositions is undoubtedly the main point of the study of computational questions,which has a more direct guiding effect on the solution of the problem of chemical calculation class in middle school.Secondly,the focus of the research is on the analysis of the basic concepts and basic knowledge involved in chemical calculation,while the thinking of scientific analysis problems,the basic methods of solving problems and the ability to solve problems in an integrated manner are the difficulties of the study of computational test questions.This paper aims at understanding the propositional law and changing trend of the chemical calculation questions in the national volume in recent years,and with the support of the theory of problem solving theory,constructivism learning theory,SOLO classification evaluation theory and so on,taking the research methods of the chemical calculation class as the research subject,using the research methods of literature investigation,text statistical analysis,teacher-student interview summary,etc.and the score of the higher examination chemistry calculation class in the three test papers of 2015-2019.The examination content,difficulty level and the core quality of the subject involved are analyzed and analyzed,and further analyzed and contrasted with the specific chemical calculation class,and the characteristics of the proposition of chemical calculation are basic and time-based.Finally,the results of statistical analysis and the teaching status quo of teachers and students interviews are based on the results of the two,for the collegeentrance examination chemistry calculation teaching a series of more objective and effective preparation strategies.The research of this paper mainly expounds from the following aspects:The first part is the introduction part,mainly expounds the background and current situation of the research,the purpose of the study and the main research content and methods involved in the research.The second part mainly introduces the necessary theoretical basis and theoretical definition for the study of the chemistry calculation test questions in this paper,and provides theoretical support for the statistical analysis of the test questions.The third part is to carry out preliminary data statistics and comparative analysis of the chemical calculation questions in the 2015-2019 national I,II,III,volume,mainly from the point-of-point question type,content level and test point examination outline,etc.to carry out the specific exploration and analysis,to explore the characteristics and changes of the university entrance examination chemical calculation propositions and trends.The fourth part is on the basis of the statistical analysis of the 2015-2019 national I,II,III volumes combined with the specific real samples,grasp the characteristics of propositions and change trends,and summarize the current situation and difficulties of students in solving computational problems according to the interviews between teachers and students,put forward the corresponding preparation strategies and suggestions.The last part is the reflection and prospect of the research,mainly including a simple summary of the conclusion of the study and the shortcomings in the reflection study,as well as the prospect of the research.
