A Study On Mathematics Situational Teaching In Junior Middle School Based On Model Thought

"Compulsory Education Mathematics Curriculum Standards(2011 edition)" put forward the idea of model and advocated the concept of situational teaching.Situations are the bridge between mathematics and reality,making it easier for students to understand and learn mathematics.At the same time,teachers infiltrate model ideas in situations,which can improve students' curiosity and application ability of mathematics.When model ideas and mathematical situations are integrated into the learning process,students' understanding of the value of mathematics will gradually improve,thus increasing their interest in mathematics.For this reason,the model-based situational teaching in junior high school is chosen as the theme for research.Firstly,by consulting the relevant literature,we collected and sorted out the relevant research on the situation teaching and model thinking in junior high school.After reviewing the literature,it defines the core conceptual model and situational teaching.Secondly,through questionnaires,tests and interviews with teachers among the students in Grade 8 and 9 of A school in Xinxiang City,the following conclusions are drawn.Firstly,the idea of model is seldom mentioned by teachers in the classroom.Most teachers create situations in the classroom,and students basically recognize the situation teaching.Secondly,students' test results show that in the field of content,the score rate of number and algebra module is lower,while the overall score of figure and geometry,statistics and probability is higher.It is also found that the higher the grade,the higher the level of comprehension,the higher the level of situational awareness;the higher the grade,the lower the students' classroom activity.In view of these phenomena,further interviews with the teachers of A school showed that the learning pressure of the ninth grade students was greater than that of the eighth grade students,and the classroom teaching atmosphere of the eighth grade was more active.Thirdly,interviews with five junior high school math teachers in school A show that model thinking and situational teaching are very important for students' math learning and future development.Thirdly,through the application of three infiltration model ideas in situational teaching,the city-level high-quality courses Median,Number Rules in Calendar and First Function are analyzed.Summarize the five common characteristics of the case: 1.Create situations,close to life,diversified situations;2.Rich mathematical activities,team communication;3.Show the essence of mathematics,highlight mathematical ideas;4.Systematize teaching mode;5.Be good at using teaching tools to enrich students' experience.Finally,combined with the conclusions of the investigation and analysis,and according to the characteristics of the high-quality cases sorted out,Five suggestions are put forward to infiltrate the idea of model into the situational teaching of junior middle school mathematics: 1.diversification of situation;2.enrichment of activities;3.idealization of mathematics;4.modelization of teaching process;5.diversification of teaching tools,which can provide reference for teaching workers.
