Research And Teaching Strategies Of College Entrance Examination Questions To Improve

"College entrance examination" is the abbreviation of the national unified examination for college enrollment,and it is a way to select talents for college enrollment.Through "recovery and development" “ From the exploration period of standardization reform,reform in-depth period and comprehensive test to the innovation period under the current curriculum standard,from knowledge and skills,emotional attitude and values to improving students' scientific literacy,and focusing on the future development of students,the college entrance examination has been constantly updated and reformed in the content and form of examination.Based on the situation of the students in our school,we choose organic chemistry foundation as the topic of "material structure and nature" and "Organic Chemistry Foundation".Organic chemistry is not only of great significance to life,production,agriculture,environment,biology,ocean,materials,science and technology,and social progress,but also has a total of 21 points in the "Organic Chemistry Foundation" module in the college entrance examination,accounting for nearly the score in the college entrance examination.The contents involved in the textbook are compulsory two and elective five organic chemistry foundation.The content includes the classification,composition and structure,nomenclature,properties,application of organic compounds and research methods of general organic compounds.Through the students' learning of the representative substances of various organic compounds,such as methane,ethylene,acetylene,benzene,bromoethane,ethanol,phenol,acetaldehyde,acetic acid,ethyl acetate,etc.,to stimulate the students' interest in learning organic chemistry,establish their confidence in learning chemistry,so as to cultivate andimprove their scientific literacy and patriotic feelings.It is very important and significant to study the "Organic Chemistry Foundation" module test questions and the teaching and solving strategies of organic chemistry in senior high school.In order to train students comprehensively,how to examine the "Organic Chemistry Foundation" part? When students are learning organic chemistry,what are the limitations in basic knowledge cognition,thinking ability construction and problem-solving of integrating theory with practice? How can students understand the structure of organic matter and grasp the nature of organic matter so that they can solve problems easily when organic chemistry theory is combined with practice? How to rely on the study and implementation of organic chemistry foundation,deepen the students' basic knowledge,improve the ability of knowledge transfer,theory and practice to solve specific problems? I hope that through the research,I will explore and analyze the above questions,and get the answers.With the help of this research,I can provide reference for the teaching of organic chemistry.Therefore,through the research and analysis of 2017-2019 national Volume I,II and III "Organic Chemistry Foundation" test questions,the paper structure,test type,test knowledge content,core literacy and test characteristics are selected to sort out and summarize,and the hot spots and difficulties of "Organic Chemistry Foundation" test questions in recent years are obtained,and the difficulties existing in students' learning and mastering are also pointed out,The teaching strategy for "Organic Chemistry Foundation" and the problem solving strategy for the national volume are worked out,which are thought map construction strategy,construction model,multimedia combination strategy,knowledge and ability transfer strategy.In the process of teaching practice,the application of thinking map construction and other teaching strategies,through the test results,shows that the application of teaching strategies plays an important role in improving learning performance and scientific literacy of students.It can provide some reference for teachers' teaching,constantly improve their professional level,and also provide methods for students to learn "Organic Chemistry Foundation".In the process of learning,we should realize the accumulation of knowledge,the formation of thinking mode,the improvement of problem-solving ability and the desire for more comprehensive development.
