Research On The Teaching Of Mathematics Proposition In Senior High School Based On PBL Model

PBL,known as ’ Problem-Based Learning ’.PBL emphasizes students ’ active learning.Teachers set reasonable tasks.Students solve problems through independent learning,group discussion and cooperative inquiry in meaningful problem situations,evaluate each other,complete tasks,and gain knowledge.At the same time,divergent thinking,improve skills,cultivate independent inquiry and cooperative communication skills.In recent years,PBL has received extensive attention from the education sector at home and abroad.Mathematical proposition is the connection between concepts,including theorems,axioms,formulas,rules and inferences.Mathematical proposition teaching is an important part of mathematics teaching,and it is also the basis of mathematical problem solving.The quality of mathematical proposition teaching is related to the achievement of students’ mathematical core literacy and affects the level of mathematics classroom teaching.Mathematical proposition teaching has a natural internal relationship with PBL.Whether it is proposition acquisition or proposition proof,or proposition application,teachers need to set reasonable mathematical tasks,put propositions in meaningful problem situations,stimulate students’ mathematical thinking,solve problems and complete tasks through independent learning,group discussion and cooperative inquiry.It is of practical significance to carry out the research of high school mathematics proposition teaching based on PBL mode.So,what is the current situation of high school mathematics proposition teaching and learning ? How to effectively use PBL teaching model to improve the effect of proposition teaching ? And so on,are worthy of study.This paper uses the literature research method to summarize the mathematical proposition teaching and PBL teaching mode,to understand the progress of related research and analyze the existing problems and deficiencies.The survey method is used to investigate a part of teachers and students in senior high school,aiming to understand the current situation of mathematics proposition teaching and learning in senior high school and find out the problems.According to the results of practical investigation and theoretical analysis,the mathematical proposition teaching mode based on PBL is constructed,including pre-class preparation,teaching links,teaching evaluation,and teaching cases are given.Finally,the experimental method is used to implement the new teaching mode.Control the relevant variables,test the experimental class and the control class,and analyze the results.The conclusions are as follows :(1)Through the comparison of the scores before and after the test,it is found that the scores of the students in the experimental class are significantly improved,while the scores of the control class are not significantly different.By analyzing the post-test scores of the two classes,it is found that the scores of the experimental class are significantly better than those of the control class,and the two are no longer parallel classes,indicating that the PBL-based mathematical proposition teaching model has achieved good results;(2)The results show that the PBL-based mathematical proposition teaching model is more effective for good students,but there is no significant difference in gender.
