Research On The Compilation And Teaching Implementation Of The Exercises Of Junior Middle School Mathematical Unit Reviews

Exercises are an important part of high school mathematics learning.Students can consolidate their knowledge,accumulate learning experience,broaden thinking,and cultivate their mathematical literacy by participating in the process of doing the exercises.The quadratic function is not only a difficult point in the junior high school function,but also the basis of high school function learning.At present,the mathematics in the middle school entrance examination pays attention to the examination of the students' basic knowledge and the mathematical ability.In order to better connect the middle school entrance examinations,this paper starts the preparation and teaching implementation of the exercises in the junior high school mathematics unit review--taking the "quadratic function" as an example.We use the methods of literature research questionnaire survey methods,interview survey methods and classroom observation methods.Firstly,through collecting and reviewing the literature,sorting out the teaching status and related theories of the secondary function learning.Secondly,through the questionnaire survey of the students,we find out the learning situation and existing problems of the students.Then through interviews with the teachers,the interview results are analyzed and the classification of the questions and the characteristics of the exercises were determined.Finally,the exercises are formulated and implemented according to the students' cognitive level and teaching theory,and the results of the research are analyzed through interviews with students and the completion of the assignments.The main conclusions of this study are as follows: Firstly,the characteristics that should be paid attention to in the exercises are: novel context,examination of core knowledge,openness of the solution and generality of the problem.Secondly,the knowledge level,problem level and question type characteristics of the quadratic function are determined,and four types of problems in the unit review are determined: the analytic formula of quadratic function,the analytic formula of quadratic function,and the parsing with quadratic function comprehensive questions and new definitions.Thirdly,select basic exercises according to the characteristics of the exercises and the students' learning situation,and carry out the preparation and implementation of the exercises.From simple to difficult,and progressively,it helps students to sort out the knowledge and enhance students' reorganization knowledge ability.Enhance students' ability to reorganize knowledge and promote the migration of learning methods.
