Statistical Analysis And Teaching Practice Of Chemical Process Flow Chart In College Entrance Examination

In recent years,chemical process flow chart,as one of the required items in the chemistry test paper of college entrance examination,has the characteristics of novel situation,large amount of information,wide range of knowledge,strong comprehensiveness and great difficulty differentiation.Based on the real chemical production situation and rich information presentation,this question type mainly examines the important content of high school chemical knowledge system,which plays an important role in guiding students to use the necessary chemical knowledge to solve practical problems in chemical production,and improving students’ key ability and core discipline quality.Therefore,the statistical analysis and teaching practice of chemical process flow chart in college entrance examination is a worthy research topic.The main content of this paper is to make a statistical analysis of the chemical process flow chart in the college entrance examination papers.Based on the survey results,this paper puts forward and applies the special review strategy for teaching practice research.First of all,the chemical process flow chart of national papers from 2016 to 2020 and the chemical test papers of Shandong,Hainan and Beijing in 2020 were selected as the research objects.This paper mainly carries out quantitative statistics and qualitative analysis from the aspects of the number and score of test questions,the situation and information presentation of test questions,the core elements and test sites,and the level of academic quality,so as to provide reference for special teaching research and review.After that,questionnaire and interview survey method were used to investigate the teachers and students of different schools in Handan City,Hebei Province,in order to understand the current review status and teaching strategies of chemical process flow chart.Based on the survey results and relevant learning theories,six special review strategies were put forward and applied to teaching design.Finally,choosing M middle school in Handan City,Hebei Province to carry out teaching practice activities,and analyze its effectiveness.Through the statistical analysis of the chemistry process flow chart questions of the college entrance examination,it is found that the college entrance examination questions pay great attention to the comprehensive examination of subject knowledge,ability and accomplishment.The teaching practice shows that the six review strategies proposed in this research are of great help to overcome the students’ fear,consolidate the necessary knowledge of chemistry,improve the key ability and quality of the subject,and can effectively improve the review and teaching status of chemical process flow chart in college entrance examination.
