Study On Mathematics Unit Review Class Based On Exercises Chain

In the teaching of mathematics unit review course in junior middle school,exercise teaching occupies most of the time in class teaching.It is an important part of students' learning basic knowledge and the ability to form mathematics.But there are many shortcomings in the current problem teaching.Therefore,it is of great significance to study the exercise teaching strategies in unit revision.This research adopts the methods of literature review,questionnaire and case analysis to investigate the current situation of exercise teaching in unit review.First of all,the author read a large number of papers related to mathematical unit review and exercise teaching,and designed a questionnaire for unit reviewing strategies of problem chain.Then taking all the students of eight(1)and eight(2)classes of a school as the investigation object,the practical questionnaire and face-to-face interviews were carried out to the students.The actual situations of the problem chain teaching in the unit review which was analyzed with EXCEL as a tool are as follows:(1)Most of the students generally recognized that the review of the unit exercises was very important.(2)Mathematics "exercises chain" is welcomed by most students.(3)Educators did not sum up the rules of solving problems according to the exercises in the exercise chain,which made the educated more confused.According to the problems existing in the teaching of exercise chain unit,the application strategy of exercise chain in unit review teaching is described in detail: preview link in pre class exercise chain,review of basic knowledge points,practice link of basic exercise chain,realization of knowledge key points,construction of knowledge network system;The practice link of the exercise chain is summed up and summed up and summed up,expanding the practice link of the practice problem chain,cultivating the students' thinking ability in mathematics,rethinking the practice links of the exercise chain after class,cultivating the ability to reflect and arousing the interest of learning mathematics.Finally,based on the application strategy of exercise chain,the effect of unit reviewteaching on exercise chain is studied.This experiment,with two classes in grade eight in a school as experimental subjects,takes eight 1 class students as experimental class and eight 2students as the control class.Excel statistical charts and spss22.0 statistics were used to deal with the data of this experiment.From the results of the survey,we can see that most of the students have approved the model of mathematical unit review of the exercise chain.The students' ability to solve problems by applying mathematics has been improved,and the habit of reflection has been developed as well.
