Research On The Classroom Teaching Strategies Of Elementary School Mathematics Under The Guidance Of "core Issues"

The development of students' mathematical core literacy,the trend of classroom reform and the call of teachers' professional development all require students to have good mathematical ability and rational thinking mode.It is necessary to cultivate students' consciousness of autonomous learning and make their mathematical thinking more profound and broad.The primary school mathematics classroom teaching under the guidance of "core problems" is a teaching mode that runs through the whole class by solving "core problems",an effective way to achieve the objectives of the new mathematics curriculum,and a trend and trend of the reform of mathematics classroom teaching.This paper expounds the connotation of primary school mathematics classroom teaching under the guidance of "core problems" and its related theoretical basis,constructs the primary school mathematics classroom teaching mode under the guidance of "core problems",gives the operation process of the mode,and combines the primary school mathematics classroom teaching practice,gives the experimental lessons of the primary school mathematics classroom teaching mode under the guidance of "core problems".The research shows that the teaching mode has certain research value,and has guiding significance for improving the efficiency of learning activities,cultivating students' questioning consciousness and questioning spirit,and cultivating students' learning ability of independent thinking,independent inquiry,cooperation and communication.However,it is not easy to extract and implement the core issues,which contains reflection on experience,interpretation of textbooks,knowledge mining,the capture of learning,the pursuit of value.At the same time,it also requires teachers to have the ability to integrate resources,flexible organization,wisdom allocation and so on.Therefore,this exploratory teaching mode needs to be continuously studied and improved.Using the methods of literature,questionnaire,case study and action research,this study summarizes four characteristics of the primary school mathematics classroom led by "core problems" : scattered form but not scattered spirit;leading to topics with dialogic nature;deep dialogue involved in deep learning;real problems driving effective learning.This paper hopes to focus on the field of number and algebra,provide some teaching records,research and analysis,explore the characteristics and implementation strategies of core issues leading classroom teaching,update teachers' teaching ideas and ideas,change teachers' preparation methods,change students' learning methods,expand the "breadth" and "depth" of mathematics classroom,cultivate students' core literacy,and let students At the same time of learning knowledge,get the promotion of thinking and realize the life dialogue and growth of teachers and students.
