The Statistical Analysis And Targeted Teaching Strategies Research Of Shandong College Entrance Examination Chemistry Experiment Questions In The Past Five Years

National College Entrance Examnation(NEMT)is a kind of talent selection system generally implemented,and it is the highest standard of cultural education selection examination in our country.Chemistry is an important subject in NEMT.It is a basic subject that studies the composition,structure,properties,transformation and application of substances at the atomic and molecular levels.Chemistry distinguished from other subjects is an experiment-based science.Therefore,the chemistry experiment part is always the important and difficult point in chemistry teaching,and is also the important examination point in NEMT.This study used the methods of literature analysis,action study and interviews with teachers and comprehensive induction to research NEMT chemistry experiment in nearly five years in Shandong,and had carried on the data statistical analysis,trying to carry on the qualitative and quantitative research on the basis of the statistics on scores,types,presentation,content levels,cognitive levels,exam point,and chemistry core literacy.It explored the trend and characteristics of Shandong chemistry experiment questions,and provided first-line teachers of chemistry experiment teaching and the examinee's note with certain reference data.In addition,in view of the current situation of chemistry experiment teaching,25 senior high school first-line chemistry teachers from different regions and in different levels in Shandong were interviewed deeply to understand the current situation of chemistry experiment teaching in Shandong.According to the statistics & analysis of the experimental questions and the teacher interviews with 25 front-line teachers,targeted teaching strategies were proposed,and the comprehensive application of relevant teaching strategies was carried out to practice teaching,so as to draw research conclusions.That is to say,the comprehensive application of relevant teaching strategies can increase students' interest in learning chemistry experiments,increase the score rate of students' chemistry experiments,and improve students' chemistry score.This research utilized the method of combining the data statistics and the teacher interviews,proposed targeted teaching strategies and implemented them through teaching practice to draw conclusions.It is a systematic and scientific research process.
