Analysis Of Chemistry Multiple Choice Questions For College Entrance Examination 2010-2019

With the reform of chemistry teaching in the 6-choice-3 mode of Ningxia College Entrance Examination,the development law of controlling college entrance examination chemistry questions has become one of the focuses of many scholars.In order to promote teachers and students to better adapt to the new college entrance examination questions,this paper selects the most representative multiple choice questions in the college entrance examination chemistry test questions as the research object,and summarizes the chemistry choices through the research analysis of the selection questions,student test scores and teaching practice The specific changes of the test questions.Provides a reliable basis for the reform of college entrance examination chemistry,so as to promote chemistry teaching to better adapt to the 6-choose-3 model.This research mainly starts from three modules of test questions,students and practice,and six small parts.The specific contents are as follows:Part I:Introduction.The thesis presents the research background from three levels:national level,disciplinary level,and current status;based on the research status,it proposes text analysis,comparative research,action research and other theoretical methods to carry out the 2010-2019 Ningxia college entrance examination chemistry selection questions.Research;determine the basic framework of the thesis through content research and lay the guidance for the development of the thesis.Part II:Analysis of selected test questions from 2010 to 2019.First,the horizontal analysis of the 2010-2019 test questions reveals the internal changes of the annual test questions;second,the vertical analysis of the 2010-2019 selected test questions and summarizes the changes of the selected test questions in different periods;again,the 2010-2019 exams The outline and the analysis of the new and old curriculum standards summarize the rules of the examination outline.Finally,a comparative analysis of the selected test questions of each province from 2016 to 2019 to study the development trend of the chemistry selection questions of the college entrance examination in Ningxia.Part III:Analysis of questionnaire survey.Through a questionnaire survey on some senior high school students in a middle school in Ningxia,they found that students had a negative attitude towards multiple choice questions.For example,they did not classify the test questions and the materials did not accumulate.The multiple choice questions that balance related knowledge are the most difficult.Part IV:Analysis and discussion of test scores.Through the SPSS software,the quantitative analysis of the achievements in each year from 2010 to 2019 is summarized,and the trend of student achievements is summarized;on the basis of student achievements,the types of wrong questions of students with 18 points to 24 points and 30 points to 36 points are compared to summarize the different scores.Types of students' wrong questions.Part V:Teaching practice and implementation.Based on the analysis of test scores,we determined the three major cases of secondary batteries based on material research,the isomers based on inheritance and development,and the acid-base titration image based on literacy innovation,and implemented the three major cases.Help students better grasp the new changes in the college entrance examination.Part VI:Research conclusions and prospects.Through the study of the three modules:in the aspect of test questions,in the horizontal analysis,the test question types appear in 9 choices 5 plus 2 modes,the option types are repeated,the material of the question is innovative and diversified,the investigation content is deepened,and the highlights are innovative.;In the longitudinal analysis of the new curriculum standard in the national paper period,the test questions as a whole appear basic,the new curriculum standard in the national paper ? period,the overall test questions show a change,the national paper II period,the overall test questions show an innovative;the exam outline from stable to slightly The changes will change to major ones,and the course standards will guide the examination outline;the electrochemical type test questions will develop in the direction of the electrochemical innovation type of each province and city,and the image type test questions will transition to the image types of various provinces and cities.The remaining test question types are basically consistent with other provinces and cities.In terms of students,the 10-year mean and standard deviation changes are relatively small,and the scores are relatively stable.The number of people in the 18-24 and 30-36 segments is relatively large.The normal distribution of student performance is right-biased.Among the 18-24 points and 30-36 points,the electrochemical type test questions have the most errors,and the element periodic law type test questions have the least errors.The students with 18 points-24 points have poor grasp of the isomers,and the students with two points It is also poor to grasp the new question types of titration analysis images.In terms of teaching,teachers should connect the textbook materials with the real questions of the exam,and pass on the consistency of the test questions and the reference between the test questions of the provinces and cities to the students.Finally,through the research of this paper,we can better control the direction of test questions,promote the integrated development of teaching and learning,and provide reference and reference for chemistry teachers to understand the choice of test questions in Ningxia.
