Research On The Creation Of Situational Problems Of Mathematics In Primary School Driven By Primitive Ideas

Since the new curriculum reform,the creation of problem situations has been widely recognized and applied by frontline teachers in primary school mathematics teaching.At the same time,the concept of “decreasing the form and focusing on the essence” has once again been valued by mathematics education researchers and frontline teachers.Many teachers wondered "what kind of problem situation is both effective and can reflect the essence of mathematics?",the author searched the relevant literature to find that the nature of mathematics can be presented in the form of problems,that is,the primitive mathematical ideas,so the following four Question:(1)How do you define the “situational problems of mathematics in primary school” and “primitive ideas-driven”?(2)What is the status quo of the creation and implementation of the situation of effective mathematics in primary schools?(3)What are the characteristics of the effective situational problems of mathematics in primary school driven by primitive problems? What is the creation principle?(4)What are the creation strategies situational problems of mathematics in primary school driven by primitive ideas?In view of the above problems,this study defines two core concepts of “situational problems of mathematics in primary school” and “primitive ideas-driven classroom teaching” through literature review,and summarizes the analysis framework of situational problems of mathematics in primary school driven by primitive ideas.On the basis of the analysis framework,through the semi-open interviews of three teachers of different teaching ages,text analysis of the teaching monographs of eight famous special-level teachers,and the authors of the famous teachers to create problem situations in teaching and how to embody the essence of mathematics Have their own opinions,but novice teachers and ordinary teachers know enough about this.The video analysis of the teaching videos of 10 famous teachers was carried out,and the three backbone teachers in the district were observed in the classroom.The six characteristics of situational problems of mathematics in primary school driven by primitive ideas were obtained: mathematics,situationality and adaptability.Participation,development,and intuitiveness,combined with the creation of the status quo,three principles of creation: participation and fun coexistence,adaptability and development,and intuitive and mathematical unity.Based on the above-mentioned creation principles,combined with the original problem to drive the analysis framework of the effective problem situation of primary school mathematics,finally create four creation strategies,specifically: use materials,enrich the situation,analyze the content,explore the essence,rich form,active Thinking,multi-dimensional reflection,internalization concept.Combined with the fragment design points,the first-line teachers are provided with specific operational strategies.
