Research On The Strategy Of Cultivation Aboutjunior Middle School Students' Mathematicalexamination Ability Based On Variant Teaching

In the actual teaching,the author finds that many junior middle school students have a weak sense of examination questions and have not developed good habits of examination questions.The examination questions are the key and foundation for solving problems.Therefore,improving the ability of Mathematics examination questions is the key to enhance junior middle school students' ability of mathematics learning?accelerate mathematics classroom efficiency and the improvement of students' mathematics performance.Teachers should consider the specific and effective ways to improve junior middle school students' ability of examine questions.Variant teaching is an effective teaching form that is suitable for China's current national conditions.It is suitable for the development of more students' ability by setting different degree of difficulty and different backgrounds questions.So it is a fair form of teaching and conducive to the overall examine questions ability of junior middle school students.However,many junior middle school math teachers misunderstood the variant teaching as the sea tactics.They simply adapt text?data,or consult variant exercises in textbooks and teaching materials.They rarely think about how to improve students' ability through the treatment of variants,and less research on breaking the traditional variant teaching form.Therefore,the author decide use the variant teaching to improve the examination mathematics questions ability of junior middle school students to be the subject of this article.This paper finds some obstacles that cause junior middle school students to solve the problems in the form of group interviews.The interview content is used as the result of pre-survey.Based on this result,combined with literature research,the author designed and distributed questionnaire.Then statistical analyzed and summarized of the survey data several common problems of junior middle school students' examination questions obstacles and through relevant analysis,the author concluded that the variant teaching affects the mathematics ability of junior middle school students.The survey results show that several common problems encountered in the current junior middleschool students' examination questions are: 1)Imperfect knowledge system leads to difficulty in extracting knowledge when reviewing questions;2)Lack of logic to sort out the meaning of the questions leads to confusion;3)Having no strong review consciousness lead to fewer trials and no habits of reviewing trials;4)Neglecting the importance of excavating implied conditions when examining questions;5)Difficulties in interpreting mathematics and multiple translations lead to inefficient examinations;6)There is a polarization phenomenon by emotional instability.Then through the literature research combined with the investigation report,the author summarized the advantages of the variant teaching in improving the mathematics examine questions ability of junior middle school students.The author raised the following teaching strategies by the above survey results: 1)Help junior middle school students make their knowledge systems complete through conceptual variants to multi-angle understand concepts;2)Build "scaffolding" variants through procedural variants to improve the logic of junior middle school students' examination questions;3)Set up problem situations,let students design open-ended variants from the perspective of the issuer,to improve the awareness of junior middle school students' examination questions;4)Construct problem-solving variants,and guide junior middle school students to excavate implied conditions in the contrast of the questions;5)The same concept or problem represented by multivariate mathematical representation to improve the efficiency of examination questions.Finally,based on these teaching strategies,the author designed teaching cases,explore the feasibility of using variant teaching to improve the examination questions ability of junior middle school students,and further point out the limitations of this research and the future research directions.Variant teaching has obvious advantages for improving the Mathematics examine questions ability of junior middle school students,but it also depends on the treatment of variants.Teachers should develop a suit of teaching strategy that meets the examine questions ability of junior middle school students based on a full understanding of the level of students' ability development and learning,and according to these teaching strategies to deal with variants,so that can be targeted in the teaching design.
