Research On The Creation Of High School Mathematics Situation Based On Mathematics Key Competence

Situational teaching is a teaching method that takes students as the main part of learning and it enhances students' motivation.The knowledge will get easier for student to understand when the situation is created in teaching.It can also cultivate students' mathematical thinking.However,the situation in which teachers creating in actual teaching is not ideal.At present,the cultivation of students' key competences emphasized in the context of the new curriculum reform is closely related to the situation.The newly revised mathematics curriculum standards in 2017 make a positive demand that developing students' mathematics key Competence in teaching.Therefore,in order to implement the mathematics key competences better,it is particularly important to create situations in teaching.The essay mainly adopted the methods of literature research,questionnaire survey and case analysis.Firstly the paper conducted a questionnaire survey on the current situation of high school mathematics situation creation,and analyzed the inadequ acies of teachers in context creation.Secondly,it combined the problems existing in teaching,seven kinds of situational creation strategies based on mathematical key competences are proposed from the mathematical activity situation,Including cognitive situation,error situation,dynamic display situation,realistic situation,mathematical situation and comprehensive situation.And some matters were given that should be paid attention to during the teaching process,including the teacher's understanding,teaching process,students,and after-school reflections.Finally,the paper analyzed three aspects of creating the situation,the students' classroom performance and the teachi ng effect.And it put forward some corresponding improvement suggestions.This study combines mathematics key Competence with the situation creation,and research the situation creation problem from the perspective of mathematics key Competence,which is in line with the requirements of the current new curriculum standard;it is of positive significance for better implementing the cultivation of students' mathematics key Competence.And it improves the teaching of high school mathematics.
