Research On The Application Of Problem-based Teaching Model In Senior High School Mathematics

With the development of new curriculum reform,there are more and more discussions on how to teach for teachers.Traditional teaching mode has been unable to meet the requirements of contemporary society.In high school,mathematics is a very important curriculum,but in the teaching of this curriculum,teachers often use the traditional teaching mode of "cramming".For teachers,using yesterday's knowledge to teach today's students to solve tomorrow's problems has been far from meeting the requirements of the development of The Times.Therefore,educators are constantly exploring and trying new teaching models,and actively introducing many advanced teaching models."problem guidance" is one of the teaching models with unique advantages.The teaching mode of "problem guidance" carries out teaching activities with "problem solving".In the process of problem solving,students become the main body of the class,so as to improve students' independent learning ability and cultivate their thinking ability.This paper first introduces the requirements of the new curriculum reform and the present situation of high school mathematics teaching.Therefore,it is necessary to apply the teaching model of "problem guidance" in high school mathematics.Then it elaborates the significance of the research,the research status and research methods of the "problem-based learning" teaching mode at home and abroad.Secondly,the paper defines the related concepts of the teaching mode of "problem guidance" and introduces the theoretical basis of "problem guidance".Thirdly,combining the characteristics of the teaching model of "problem guidance" and the characteristics of high school mathematics,the paper gives the definition of the teaching mode of "problem guidance" in high school mathematics.Subsequently,it gives the design strategy and the general steps of application of "problem-based instruction" teaching mode in senior high school mathematics.The general application steps of the teaching mode of "problem guidance" in high school mathematics are combining practice and designing problems skillfully;Elaborate presupposition and ask questions;Encourage questioning,point to guide;In-depth analysis,explore the problem;Application exploration,problem solving;Reflect on problems and deepen understanding.Then,according to the above application steps,the paper gives teaching designs of the concept of dihedral angle and the sum of the first n terms of the sequence of equal difference numbers,and analyzes and summarizes the application effect of these two cases.The paper also reflects on the problems and shortcomings in the application of the teaching mode of "problem guidance" in high school mathematics.Finally,the paper gives the research conclusion and reflection.
