Analysis Of The Chemical Experiment Questions Based On The "One Core,Four Layers And Four Wings"

In recent years,the education reform pays attention to the inspection of students’ comprehensive quality and focuses on the cultivation of students’ discipline quality and key ability.As the highest level selection method in China,the college entrance examination has fully implemented the test question system and evaluation system-"one core,four layers and four wings".Therefore,the students’ chemical experiment ability can be measured through the students’ experimental questions.This paper discusses the theoretical basis and the college entrance examination evaluation system "one core,four layers and four wings" to test and analyze the students’ chemical experiment ability.In this paper,combined with the research results of various kinds of literature,mainly from the three aspects of the situation,content and requirements of the examination,this paper analyzes the national college entrance examination chemical experiment questions in the past five years,using the methods of list comparison,summary and induction,questionnaire survey,etc.,summarizes the examination characteristics of the college entrance examination practical examination questions,and puts forward corresponding suggestions and Reflections on the teaching of chemicalexperiments.The purpose of this study is to help front-line teachers and senior three students form systematic review strategies.First of all,through consulting the relevant literature,through the questionnaire survey of Taiyuan No.19 middle school senior three experimental class and ordinary class students and the interview with experienced teachers,it is found that the students’ score rate of chemical experiment is relatively low,and the score in the experimental data analysis and processing,the design and evaluation of experimental scheme is less,and teachers tend to ignore the cultivation of students’ core literacy and key ability It is rarely used in teaching practice,especially in experimental review teaching.Next,focusing on the examination situation,examination content,and examination requirements,it analyzes the comprehensive test questions of the national one-volume college entrance examination in the past five years,and draws the proposition characteristics of the experimental test questions based on the test question formulation and evaluation "one core,four layers and four wings".Research shows that in the content of the examination questions of the college entrance examination,we must first pay attention to basic experimental knowledge,secondly,we must pay attention to the core value of the experimental questions,and finally we must pay attention to the cultivation of subject quality and the establishment of key capabilities.In the context of examination,more attention should be paid to the context of learning and exploration and the context of life and production to guide the direction of experimental teaching,and more attention should be paid to the context of academic exploration.In terms of examination requirements,the examination of experimental test questions should not only pay attention to the basics,but also the application and innovation of the test questions.Finally,on the basis of actual investigation and theoretical support,the reflections and suggestions on the review of the third year chemistry experiment section were put forward.The review suggestions are: return to the textbook,focusmore on basic experiments,and build a complete knowledge system;extend the knowledge of experiments to improve students’ key abilities and cultivate their core literacy;break through the situational presentation methods of the test questions one by one,and practice targeted;more exposure The most cutting-edge knowledge;pay attention to the experimental design and evaluation of scientific inquiry;excavate students’ scientific inquiry ability;adjust the psychological state of students and actively prepare for exams.
