Research On High School Chemistry Teaching Strategy Based On The New College Entrance Examination Evaluation System

In January 2020,the “China College Entrance Examination Evaluation System” was officially released.This evaluation system is also called the “one core,four layers and four wings” evaluation system.“One core” is the core function of the college entrance examination,that is,“provide morality,cultivate talents,serve talents,and guide teaching”.“Four levels” refers to the content of the college entrance examination,that is,“required knowledge,subject literacy,key abilities,and core values”.The “Four Wings” are the examination requirements of the college entrance examination,that is,“basic,comprehensive,applicable,and innovative”.The proposal of the new college entrance examination evaluation system answers key questions such as “why test”,“what to test”and “how to test” from three aspects: core function,examination content,and examination requirements.The comprehensive reform of the college entrance examination in Hunan will be implemented in the fall of 2018.From the fall semester of 2020,high school students will begin to use the new version of chemistry textbooks.In the context of the new college entrance examination and the new textbook,the analysis of chemistry test questions and teaching strategy research based on the new college entrance examination evaluation system will help teachers to have an insight into the connotation of the new college entrance examination evaluation system and the direction of chemistry propositions in the college entrance examination,and promote the reform of chemistry classroom teaching,and implement the fundamental task of strengthening morality.The chemical tests of National Volume I from 2018 to 2020 are used as the research object in this paper,which using literature analysis,statistical analysis,questionnaire method and experimentation.On the basis of clarifying the connotation of the new college entrance examination evaluation system,the four levels of examination content and four aspects of the examination requirements are used to analyze the test questions and interpret the "one core,four layers and four wings" evaluation system reflected in the exam questions.Based on the analysis of the exam questions,the principles of high school chemistry teaching design based on the new college entrance examination evaluation system summarized:(1)Plan teaching goals based on curriculum standards.(2)Pay attention to the creation of real situations and strengthen the classroom experience.(3)Focus on project-based learning methods to promote deep learning.(4)Analyze problems from multiple perspectives and conduct advanced thinking training.Two teaching cases based on the new college entrance examination evaluation systemin high school chemistry teaching design were designed,"Sodium and its compounds" and "Chlorine and its compounds".And the innovative teaching design of "Sodium and Its Compounds" are applied to research on teaching practice.The results of research show that the experimental class accepting the innovative teaching case design is better as a whole than that of the control class,and has significant advantages in terms of necessary knowledge,key abilities,and subject literacy.Based on the above practical research results,a high school chemistry teaching strategy based on the new college entrance examination evaluation system is proposed:(1)Based on "textbooks",implement the teaching of necessary knowledge.(2)Use problem orientation to promote the development of key abilities in chemistry.(3)Create real situations and develop students' core literacy in chemistry.
