Research On The Teaching Model Of Junior Middle School Mathematics Proposition Experiment Based On Graphing Calculator

For nearly twenty years,mathematics experiment teaching based on modern information technology has gradually become an important content of mathematics teaching research at home and abroad.Mathematics experiment teaching is helpful to cultivate the junior middle school students' innovative consciousness,applied consciousness and mathematical modeling and other core competencies.The types of mathematical knowledge determine the different teaching methods of mathematical experiment.Based on the analysis of existing literature,this paper makes a systematic study on the teaching model of junior middle school mathematics proposition experiment based on graphing calculator by using the method of questionnaire,educational experiment and the case study.The main conclusions are as follows.Firstly,it analyzes the current situation of mathematics proposition experiment teaching in junior middle school in AH province.The results show that most junior middle school mathematics teachers hope to carry out mathematics experiment course,but lack of relevant teaching equipment,operation training and mathematical proposition teaching model for reference to guide teaching.The propositional teaching effect is not good.Teachers generally agree that guiding students to explore the formation process of propositions is beneficial to propositional teaching,but it is not reflected in the actual teaching.Secondly,under the guidance of embodied cognition theory,re-creation theory and mathematical proposition learning theory,a teaching model of junior middle school mathematics proposition experiment based on graphing calculator is constructed,and the operation procedure of the model is illustrated with a specific teaching case.Thirdly,The results of educational experiment show that it is effective of teaching model of junior middle school mathematics proposition experiment based on graphing calculator.First of all,this teaching model can effectively improve students' test scores of mathematics proposition,the results show that test scores of mathematics proposition between the experiment class and the contrast class exist significant difference.In the next place,this model plays an important role in improving students' interest in learning mathematical propositions,practical operation ability and problem exploration consciousness.
