Under The Background Of Core Literacy,the Analysis And Review Strategy Of Chemical Experiment Questions In 2016-2020 National College Entrance Examination Papers

In 2020,the latest Chemistry Curriculum Standards for General High Schools(2017 Edition 2020 Revision)issued by the Ministry of Education talked about the basic role of chemistry core literacy in students' lifelong learning and socialized development.The five core qualities aim to cultivate students' ability to observe and reason the material form and its motion and change characteristics in the micro world,grasp the relationship between chemical phenomena and models,and cultivate students' awareness of research,innovation and social responsibility.Therefore,it can be seen that "General High School Chemistry Curriculum Standards(2017 Edition2020 Revision)" has new requirements for the analysis and review of students' chemistry experiment questions in the college entrance examination,which is different from the traditional practice of practicing a lot of questions.The examination of the chemistry experiment questions in the college entrance examination is not limited to the knowledge level such as the understanding of the change form of chemical substances.The cultivation of talents in socialist countries also needs to pay attention to the cultivation of students' exploration and reasoning ability,social responsibility and other aspects.At the same time,the college entrance examination attaches great importance to the situation.It is necessary for teachers to take students' living situation into consideration when guiding them to analyze and review the chemistry experiment questions in the college entrance examination.This paper is divided into six chapters.Chapter 1,introduction.Research situation of chemical experiment teaching in China through literature research,the core literacy of the college entrance examination chemistry experiment topic analysis,review the research status quo and the development direction of chemical experiment teaching reform in our country,puts forward the core quality analysis of the importance of high school chemistry experiment,thus put forward in this paper,the research significance and the content and research methods.Chapter 2,the theoretical basis of the paper and the elaboration of related concepts.First of all,constructivism learning theory and humanism learning theory are taken as the theoretical basis of this paper,and the concept of core accomplishment,chemistry core accomplishment,one core,four layers and four wings college entrance examination evaluation system,so as to provide ideological guidance for the analysis and review of college entrance examination chemistry experiment questions in the past five years.Chapter 3,"the ordinary high school chemistry curriculum standards(2017edition,revised in 2020)in the core quality to reach a level of chemical subject has carried on the classification,it is the measure of the degree of core literacy acquisition,therefore can apply these standards to the college entrance examination chemistry experiment topic thesis level,students learn about the core of the deal literacy level measurement.Focusing on the vertical use of the five core qualities of chemistry and each quality corresponds to four different levels of horizontal analysis of the recent three years of national college entrance examination chemistry experiment questions and draw conclusions.Chapter 4,eight principles of optimization of chemistry experiment teaching are summarized,which are scientificity,safety,feasibility,intuitiveness,inquiry,timeliness,greenness and interest.Secondly,it puts forward some strategies,such as attaching importance to "double-base" teaching,making good use of scientific inquiry,setting up extracurricular interest groups in chemistry,and attaching importance to extracurricular practical activities,to cultivate students' core quality of chemistry discipline.Then it puts forward some strategies to improve the understanding of chemical experiment teaching by strengthening theoretical study and professional skills training,communicating with similar schools,and adopting the "one help one" model to improve teachers' teaching ability of experiment questions.The following,it summarizes the strategies of strengthening the management and construction of the laboratory and improving the evaluation mechanism of experimental teaching.Finally,the author designs teaching plans related to the analysis and review of chemical experiment problems based on the previous research experience to support the research results.Chapter 5,summary and reflection.The chemistry experiment questions in the college entrance examination mainly reflect the core qualities of chemistry: "scientific inquiry and innovation consciousness" and "macro identification and micro analysis".First,students can design a simple experiment plan according to the problems given in the test,observe and record the phenomena,and conduct further research on the problems in the experiment.Level 2: Students can make reasonable assumptions based on the problems,design experiments based on the assumptions,assemble experimental instruments,and complete the operation in the experiment.Level 3.Students have a strong awareness of problems,reflect on the possible problems in the experiment,and draw reasonable conclusions according to the phenomena.At present,the research on the core accomplishment of chemical experiment has just started.Due to the limitation of time and my own energy,the methods and strategies proposed by the author still need to be gradually improved in the future teaching practice.
