The Research Of One-round Review Strategy About Organic Inference Questions On High School Chemistry

As an important branch of chemistry,Organic Chemistry is an important part of high school chemistry knowledge.It is helpful for students to learn Organic Chemistry to explore the world scientifically.It is of great importance to study the teaching methods,the ways of solving problems and the reviewing strategies of high school Organic Chemistry.Although Organic Chemistry is a selective compulsory course,the proportion is very large in the College entrance examination.The Organic Chemistry inference problems must appear in the?volume 38^th.It is the required question for examinees who learned basic Organic Chemistry.Therefore,review strategy for Organic Chemistry inference problems is one of the topics worth studying.This paper analyzes the problems of the college entrance examination in the field of Organic Chemical inference over the years,and summarizes the characteristics and examination methods of organic inference questions,as well as the confusion of students'inaccurate,incomplete and easy to lose points.This requires teachers to help students in the review process clear goals,know what organic inferences test;Dig the useful information in the problem stem to find the breakthrough;To master the methods and techniques of solving organic inference problems;Ensure the integrity and accuracy of the answers.Combined with information processing theory,constructivism learning theory and schema theory,a round of review strategy for the organic inference problem of chemistry in senior three is proposed.To test knowledge to consolidate the mind map or schema strategy,methods and techniques for exercises training students topic strategy,according to specification problem solving ability,improve the accuracy after class reflection strategy,and design cases in teaching practice.Based on literature research,practical research and statistical analysis,the conclusion is drawn.Students review basic knowledge through design mind mapping which is different from the traditional review methods.Through the strategy of students'problem telling,students have mastered the method of solving organic inference problems while studying the thinking,examination points,breakthrough points and error-prone points of organic inference problems.Through the after-class reflection strategy,consolidate the knowledge,clarify the thinking,methods and skills of problem solving,improve the ability of problem solving,and implement the correct rate.Analyzing the results of the comparative classes and experimental classes,combining students'classroom reflection and assignment,we comes to a conclusion that review with the above strategies,the teachers and students completed round review of Organic inference problem easily and efficiently.Review strategies strengthen the student's examination site knowledge,improve the students ability to solve problems,to standardize the answer also play a large role.Students can review the question,find out the answer,can use chemical language expression of the correct answer,which will increase the confidence of the students,make students learn more and more and gain the power,also getting better and better.The above review strategy is very applicable,effective and worthy of promotion.
