Analysis About Organic Chemistry Of College Entrance Examination And Research About Review Strategy

College entrance examination is the most important examination in all of China's selective examination. Chemistry plays an important rale in the colleage entrance examination, in which the Organic Chemistry is necessary and closely related to People's life. Therefore the study of Organic Chemistry revision strategies have received increasing attention.The Organic Chemistry questions in the colleage entrance examination were systematically analyzed and summarized. The following character:basic and applied knowledge of Organic Chemistry stand out, and questions of Organic Chemistry inference and synthesis get more attention in the topic and facts. Also ability conception is more strengthened. The writer also selected 73 middle school students from Hangu Fifth Middle School in Tianjin Binhai New Area, conducted a questionnaire survey, and analyzed summary:Most students think elective Book Five "Organic Chemistry Foundation" is much easier to grasp than elective Book four "chemical reaction principle", Regularity is much stronger. However, due to organic chemistry's more contents, miscellaneous knowledge, reaction mechanism abstract, it is difficult for students to remember them and the knowledge can not be utilized to solve problems, then it is the main cause of losing marks in organic synthesis problem and inference questions.Through the analyses of charaters of the above questions in the Organic Chemistry examination and the combination of the actual situation of students in the Organic Chemistry study. The writer came up with teaching, strategies which is innovation of thesis. During the revision of Organic Chemistry in high school, the following strategies should be taken: ? TO make mind concept map and to make students' knowledge sestermatic and structural. ? To make STS education concept and combine hot social topic to teach students.? To combine the typical examples to improve students'comprehensive ability to solve the problems.? Strengthen the practice, the practice of organic chemistry exercises are throughout the whole review of the senior high school.The writer do the experiment combining the four reversion Strategies used in the 2016 revision of the senior 3 Organic Chemistry. For example the study of Organic imply and synthesis thake the targeted teaching stategy to improve the efficiency of revision, of Organic Chemistry, and synthetic inference solving ability. Practice has proved the fasibility of the four teaching srategeies in the teaching of snior 3 Organic Chemistry. Besides, the four strategies achieved the good teaching effect, Change the way the students learn, build and apply knowledge structure and improve studentsproblem-solving skills. Which has taken obvious advantage combined with the tradition revision teaching.
