Research On The Application Of Review Plan Based On Thinking Map In Chemistry Review Class Of Grade Nine

The study plan of thinking guide schema proposed in this paper is a combination of two successful examples(mind map and study plan)in the basic education curriculum reform.The introduction of the thinking map into the review study plan is in line with the new educational concept advocated in the basic education curriculum reform.It can also solve the problems existing in the current situation of chemistry rev:iew in grade nine.Firstly,the related theories and research status are analyzed.Based on the analysis of the literature review of the the related theories and research status,the students of grade nine of Lianyuan Island Stone Middle School were investigated with questionnaires,and the chemistry teachers of Grade nine were interviewed.The purpose is to know the current situation of chemistry review in grade nine,and find out the difficulties of students in the review process.Secondly,the basic principles and framework of drawing up the revised study plan are constructed,on the basis of the relevant theoretical basis,their own teaching practice experience and the opinions of chemistry teachers in the ninth grade on the preparation of the revision study plan.According to the framework(target navigation,pre-class preparation,class presentation,transfer and application of four modules),thinking guide schema review plan of three units of the "Mystery of material composition","Chemical equation" and "Acid and Alkali" is compiled.Finally,the revised plan of thinking guide schema is used in teaching practice.Through the analysis of the results before and after the practice,the results of the investigation and interview are analyzed to verify its validity.Based on the research of this paper,the following conclusions are drawn:(1)The current situation of chemistry review among the ninth grade students in Lianyuan Island Stone Middle School is not optimistic.The students are faced with many difficulties in chemistry learning,such as the difficulty of memorizing knowledge,the inability to form a knowledge network,the inability to find ways to do problems,and so on.And the students generally study chemistry enthusiasm is not high,class attention is not focused,learning autonomy is poor,and even learning results are not ideal;(2)The principles and basic framework of this study are applicable.(3)The use of thinking guide schema review plan of three units of the "the Mysteries of material composition","Chemical equation"and "Acid and Alkali" can solve the problems in chemistry review of ninth grade.At the same time,it also plays a certain role in promoting students' ability of thinking mapping.(4)Through the comparison of the implementation effect of different chemical knowledge modules,it is found that the implementation effect of thinking guide schema review on the knowledge of elements and compounds is better than that of chemical terms.
