A Study On Situational Teaching Model Based On PBL Teaching Method In Elementary School Mathematics Classroom

School classroom teaching reform is undergoing profound reforms as a component of basic education reform.Mathematics has received great attention for its abstractness and concreteness,humanity and instrumentality.How to improve students' initiative in learning and thinking through mathematics teaching,increase students' interest in mathematics learning,and enhance students' mathematics literacy is the key to the current mathematics teaching reform.The teaching mode serves as a bridge between teaching theory and teaching practice.The exploration of teaching mode helps to improve and optimize the teaching of teachers.However,looking at the existing research,although certain results have been achieved,the research is not in-depth and operation to be considered.Therefore,this study investigates the current situation of the primary school mathematics situational teaching model,constructs a problem-based learning situational teaching model of primary school mathematics based on the theory of situational education,humanistic learning theory,and the cognitive theory of emotion regulation theoretical,and verify its effectiveness through experiments.The research first adopted the observation method to observe the mathematics teaching of 6 mathematics teachers in T elementary school for a total of 30 classes.It was found that in actual operation,teachers had the problems of creating a single type of situation,equating situational teaching with classroom introduction,and insufficient effectiveness of the situation.;Secondly,in-depth interviews with 6 teachers after class learned that teachers have given certain affirmation and attention to situational teaching,but teachers' cognition of situational teaching has misunderstandings,and teachers' skills in creating and operating situations need to be improved.About situational teaching There is a lack of relevant systematic guidance and teachers' lack of deep reflection on the situational teaching method.On this basis,based on the PBL teaching method,a problem-based learning-based primary school mathematics situational teaching model composed of six sub-models of innovative design context,questioning,independent inquiry,cooperative communication,teacher-student evaluation and problem solving is constructed.And use the experimental group and the control group single factor before and after test design to explore the validity of this model.The results found that: under certain conditions,in mathematics classrooms,compared with traditional teaching methods,teachers create effective problem situations around mathematics knowledge can bring students a better learning experience,and this experience has a certain degree of promotion for improving students' academic performance and expanding students' mathematical thinking.This research explores the implementation of the situational teaching model based on problem-based learning,points out new directions for the design and application of situational teaching methods,and provides a fixed teaching model for teachers' teaching.It is a good starting point for teachers and helps teachers improve and optimize teaching.
