Research On Application Of PBL In Junior High School Math Teaching Based On Interactive Electronic Whiteboard

Interactive whiteboard is widely used in classroom teaching information teaching means.PBL is problem-based learning,which is a problem-centered teaching model in recent years.The core of the model is to create real problem situations,to guide students to cooperate and communicate on the basis of independent inquiry,to solve the problem of no unique standard And to develop students’ ability to solve problems.This paper studies the basic problems of teaching objectives,contents,operating procedures and evaluation of PBL in interactive whiteboard environment by using literature research method,investigation method and action research method,and tries to study the basic problems of information technology and mathematics Teaching the integration of a useful attempt.The purpose of teaching is to use the interactive whiteboard to create a fresh problem situation,and to guide students to participate in the whole process of learning activities through the problem.And ultimately develop students from different disciplines point of view to solve the problem,the ability to solve the problem;Content for the difficulty of moderate or relatively simple knowledge,students can master the basic knowledge and skills on the basis of more in-depth study;The operation procedure includes four stages and seven links,including identifying the problem,analyzing the problem,solving the problem,evaluating and reflecting the four stages and determining the theme,clarifying the problem,creating the situation,presenting the problem,informing the target,introducing the method,the teacher guidance,the student Experience,group collaboration,problem solving,formation of results,group reporting,review teaching,evaluation of reflection seven links.The results are divided into two aspects:the evaluation of the students and the evaluation of the teachers.On this basis,from the perspective of the design of the teaching case "data analysis-Yinchuan and Qingdao where more livable" and carried out practical practice.Finally,the paper analyzes the application effect of PBL teaching mode based on interactive whiteboard in the mathematics classroom of junior middle school from the aspects of students’ academic achievement,learning process and ability to solve the problem.
