The Diagnostic Analysis And Strategy Research On The Problem Solving Of Junior Middle School Chemistry Information Migration Question

Chemical information migration question,an important way to examine students'literacy and highlight students' ability quality in the examination.This type of question has become a hot topic and occupied a large proportion of the chemistry exam in The Senior Entrance Exam in China.However,as a type of exam question to examine students' comprehensive quality,the chemical information migration question has become a major problem for students and teachers.Thus the error rate of information migration question is high in chemical examination papers in different regions around China.Therefore,it is important to analyze the reason of students' errors in solving information migration question and find out the root cause and then solve the question,Literature research,questionnaire,diagnostic test,oral report and statistical analysis are applyed to conduct theoretical and empirical research in this paper.The full content is divided into six parts:The first part discusses the origin of the problem and confirms the research purpose,content and research significance by investigating the research review and current situation,then introduces the research methods and ideas;The second part studies the theoretical basis of the issue.The content Includes theoretical basis,concept definition and theoretical analysis,of which the focus on exploring the information migration questions' characteristics,types and problem solving modes in junior middle school chemical exam are carried out in the research;The third part is the design of the research.According to the junior middle school chemistry discipline characteristic and the psychological development characteristics of the junior middle school students,build the "migration answer key questions of the junior high school chemistry information diagnostic tool",through the quality inspection of the tool,its reliability,validity,difficulty,degree of differentiation,all accord with the requirement of large-scale test;The fourth part is the result and analysis of the test.According to the four types of information migration question,the error rate of problem solving for each topic is counted,a deep fault diagnosis analysis is carried out,and then from the main level,it sums up the causes of junior middle school students' problem-solving errors in the transfer of chemistry information migration question.mainly has the topic disorder,characterization ability is weak,the cognitive structure defect,thought disorder,metacognition,psychogenic disorder.Based on previous theoretical analysis and empirical research,in order to diagnose the students in solving the problem of migration of chemical information of junior high school class development level of the status quo and the error of differences meticulously and comprehensively,this article on the six major problem solving error types with different sex,different educational level students diagnostic test and comparison analysis;As a whole,there is no significant difference between male and female students in solving the problem of middle school chemistry information migration question,but there are differences in the types of problem solving.Boys in solving migration problem of junior high school chemistry information frequency percentage defect size is cognitive structure defects>error of examination>thinking disorder = metacognitive>psychogenic disorder>representation ability is weak;Girls in solving migration problem of junior high school chemistry information frequency percentage defect size is thinking disorder>cognitive structure defects>metacognitive>representation ability is weak>error of examination>psychogenic disorder;In addition,in the academic level,through the single factor ANOVA(LSD)and students of different academic levels on the score of descriptive statistics,eugenics and the birth,eugenics and trap birth,biological and chemical trapped in the three groups of students in junior middle school chemistry information migration problem solving level exists significant differences.Eugenics in solving junior middle school chemistry information transfer problem mistakes frequency percentage is error of examination>psychogenic disorder>cognitive structure defects>metacognitive>representation ability weak>thinking disorder;Born in solving the junior high school chemistry in information migration problem when error percentage frequency size is thinking disorder>error of examination>representation ability is weak>psychogenic disorder>metacognitive;Trapped born in solving the junior middle school chemistry information migration problem when error percentage frequency size is cognitive structure defect>weak characterization of adverse>metacognitive>psychogenic disorder>thinking disorder>error of examination;The fifth part put forward teaching strategies to reduce chemical information migration question errors of junior high school students in order to provide effective teaching operability and practical guidance for teachers.The content concludes improving the ability of examination questions,promoting effective characterization,paying attention to method guidance,improving cognitive structure,carrying out strategy training to overcome the mental obstacle,improving metacognitive level by make the best use of the wrong question and regulating negative psychology and enhance self-efficacy;The sixth part carries out the summary and reflection of this research.
