Investigation And Research On The Rresent Situation Of Senior High School Mathematics Review Lesson

As one of the most important types of mathematics classroom teaching in senior high school,the main task of chapter review course is based on the basic knowledge and methods,through combing and induction,to help students to make the scattered mathematical knowledge in their mind to connect with each other,to construct the systematic knowledge structure,and through the typical examples’ teaching,to summarize the problem solving method,to refine the mathematical thought,to deepen students’ understanding of the nature of mathematics,so as to improve the students’ ability of comprehensive application an using knowledge to solve the problem.However,in the current students’ mathematics learning,the phenomenon of“a listen to understand,a look will do wrong”is common.This not only reflects the students’ mastery of basic knowledge is fragmented and without constructing cognitive structure system,but also reflects the students’ poor thinking ability,they can’t use the knowledge and skills flexibly.As the leader of teaching,the teacher’s task is to help the students to construct the knowledge system,to guide the students to sum up the methods of thinking and improve the ability of comprehensive application of knowledge to solve problem.The emergence of above phenomenon shows that there are some problems in the current chapter review teaching,which has a great relationship with teachers,so that it’s difficult for the students to achieve the ideal goal.In order to improve the present situation and the efficiency of review,this paper makes an investigation and research on the present situation of high school mathematics review lesson from the perspective of teachers.The main contents are as follows:(1)The teachers’ understanding and target location of mathematical chapter review lessons in the high school;(2)The teachers’ design process of high school mathematical review lessons;(3)The general pattern of the classroom teaching of the high school mathematical review lessons;(4)The advantages and disadvantages of the high school mathematics review lessons.Finally,the author put forward specific suggestions for the problems in the review lessons.Through the questionnaires survey and case analysis,we got three advantages and fivedisadvantages of the current chapter review class teaching,the advantages are:(1)It’s clear for the teachers to recognize the target of chapter review;(2)The chapter review of the teaching structure tends to assimilation,teachers strive to model innovation;(3)The teachers pay more attention to the cultivation of students’ ability to solve problems while paying attention to the basic knowledge.The problems are:(1)The teachers don’t conform to the actual teaching emphasis on the goal orientation of the review lesson;(2)The teaching of knowledge combing with simple repetition as the main form,teachers ignore the construction of knowledge network;(3)Teachers pay too much attention to training questions,so ignore to make students to deep understanding of mathematical knowledge;(4)Teachers ignore the summary link;(5)The students’ participation is not high,and their main status is not reflected.Finally,this paper aims at these deficiencies,from three aspects such as the knowledge combing teaching,the example of teaching,and the inductive summary teaching to put forward specific teaching suggestions:(1)The teachers can help students to card knowledge systematically,construct network by using the mind map,so as to strengthen the teaching of knowledge;(2)Using the comprehensive practice and the variant training to carry out the problem solving teaching,to deepen students’ understanding of knowledge and improve their ability to use knowledge flexibly;(3)Falling to the point of emphasizing the main points and refining ideas,to set up summary link carefully,then cultivating the students’ reflective haibits.
