| Under the guidance of “5E” teaching mode,this paper investigates the current situation of junior middle school mathematics core concept teaching,and provides some targeted teaching strategies,so as to provide a new teaching mode for the majority of junior middle school mathematics teachers.This paper mainly uses the methods of literature research,questionnaire survey and case analysis to carry out the teaching strategy research of junior high school mathematics core concepts based on “5E” Teaching Mode.In order to study this problem,this paper analyzes the causes of the problems existing in the teacher questionnaire,and puts forward the corresponding teaching strategies to solve the problems.Through the investigation and research,it is found that the following problems exist in the teaching of junior high school mathematics core concepts: the purpose of the attraction link is not clear enough;the design of the inquiry link is too formalized;the explanation link does not attract enough attention;the transfer link does not highlight the role of students as the main body;the evaluation link does not achieve multiple evaluation.The main reasons are that there is a certain deviation in the purpose of the attraction link;students exploration ability is insufficient;class size is too large;teachers role transformation is difficult;teaching task is too heavy.In view of the problems existing in the core concepts of junior middle school mathematics and the analysis of the reasons,combined with the “5E” teaching mode,this paper puts forward the corresponding teaching strategies.The introduction of link strategy is to understand the core concepts of mathematics with the help of modern information technology;be good at putting forward mathematical problems related to real life;be good at selecting interesting cultural materials related to mathematics.The teaching strategy of the inquiry link is to create the problem situation and personally perceive the process of the formation of mathematical concepts;teachers should be forward-looking in the inquiry process;clear the main position of students inquiry,and teachers should guide them appropriately when necessary.The teaching strategy of explanation is to use concept map to improve students mathematical thinking;to give the explanation of concepts on the basis of students existing experience;to combine number with shape.The teaching strategy of transfer is to make clear the main position of students and form the core concept system of mathematics;to distinguish positive and negative examples of mathematics and promote transfer;to associate analogy and deeply understand the essence of core concepts.The teaching strategy of evaluation is to pay attention to students dominant position,combine students evaluation with mutual evaluation,and diversify the evaluation content.According to the proposed teaching strategies,this paper designs the teaching of “the power of a power”,“the positional relationship between circles” and “the equation of one degree”,and takes “the power of a power” as an example to carry out the teaching experiment and analysis of the core concept of junior high school mathematics based on “5E” teaching mode.Based on the practical research,it comes to the conclusion that “5E” mathematical mode is not only beneficial to the teaching of junior high school mathematics For students to understand,master and apply the core concepts of mathematics,it is more important to enhance students learning emotion of mathematics and cultivate students comprehensive ability,so as to realize students all-round development. |
