Research On The Methods Of High School Mathematics Class Lead-in

A complete class contains multiple teaching works: pre-class work,intra-class work and post-class work.In each link,there are many specific teaching links.Intra-class work is the main part of teaching,among which the way of lead-in is an important one.Based on the current situation of high school mathematics classroom teaching,this paper expounds the significance of the problem,the research focus and the core concepts.On the basis of studying and consulting relevant theories and literatures,this paper studies the introduction method of mathematics classroom based on the teaching and learning conditions of teachers and students in two senior middle schools in Heyuan city,Guangdong province.Through the questionnaire,With the help of recycled data,analyze some problems existing in the current classroom introduction of high school mathematics.For example,teachers pay little attention to the introduction design of the classroom,have an unscientific grasp of the introduction time of the classroom,attach different importance to the introduction of different types of classes,and are not innovative enough to the introduction design of the classroom.For example,some students do not know what is called the introduction of a class,students do not like the teacher's way of introduction.Then,the paper tries to discuss some characteristics of the effective introduction of high school mathematics classroom,and expounds some common problems in the process of the introduction of high school mathematics classroom.Finally,with the help of specific classroom examples,this paper explains how to use the method of review lead-in,problem situation lead-in,intuitive or experiment lead-in,analog lead-in,story description lead-in,game lead-in,problem-driven lead-in,suspense lead-in to begin the classroom,try to explain how to choose a better lead-in method among the different classes.For example,in some classes with strong continuity of knowledge,we choose themethod of review lead-in to teach.In some of the more applicable classes,we choose the method of problem situation introduction to teach.In some classes with similar knowledge or solutions,we choose to use analogical approach for teaching.In review classes,choose to use a problem-driven approach to teach and so on.
