Research On Teaching Strategy Of Mathematics Concept In High School Oriented To Mathematics Abstract Core Accomplishment

Currently,mathematics core literacy is a hot topic in the field of mathematics education.Abstract core literacy of mathematics,as the primary core literacy of high school mathematics,plays an important role in the personal growth and development of students,and it is of great significance to study its cultivation.Based on the process of high school mathematics concept teaching,this study adopts literature analysis method,questionnaire survey method,test method and data analysis method to study the cultivation strategy of mathematics abstract core literacy.The research process is as follows:Firstly,this study analyzes and makes an in-depth study on the research status of mathematics abstract core literacy and mathematics concept teaching at home and abroad,laying a theoretical foundation for the research.On this basis,taking an ordinary high school in H city,A province as an example,this paper investigates the current situation of high school mathematics concept teaching through questionnaires and the development of high school mathematics abstract core literacy through test papers.The following conclusions are drawn :(1)the current high school students have A strong awareness of mathematics concept learning,but the habit of concept learning needs to be improved.(2)Currently,high school mathematics teachers have a good cognition of mathematics abstract core literacy and attach importance to mathematics concept teaching.However,the strategies of cultivating students' mathematics abstract core literacy in concept teaching need to be improved.(3)Currently,high school students can generally reach the first level of mathematics abstract core literacy,nearly60% of students can reach the second level,only a very few students can reach the third level.Based on this,this study puts forward ten teaching strategies of mathematics concept from four stages of concept teaching,which point to the core accomplishment of mathematics abstraction.(1)In the stage of concept introduction,students are helped to establish conceptual linking points and perceive mathematical concepts by creating reasonable teaching situations and presenting intuitive and perceptual materials.(2)In the stage of concept formation,analogy development helps students abstract the essence of mathematical concepts and accumulate experience of abstract activities through case analysis,operation practice and concept similarity.(3)In the stage of concept deepening,students can understand mathematical concepts and strengthen mathematical abstract thinking through comparison of positive and negative examples,variable training and multiple representation.(4)In the concept application stage,students are encouraged to develop the core quality of mathematical abstraction through problem solving,comprehending the connectivity method of mathematics,using mind mapping and sorting out the concept system.Furthermore,this study applies the above teaching strategies to the teaching design of the concept and properties of high school functions,forming the teaching optimization design of the concept and properties of high school functions.Finally,the effectiveness of the above teaching strategies is tested through teaching experiments.It has been verified that the ten concept teaching strategies proposed by the author can effectively promote students' understanding of mathematical concepts and play a certain role in improving students' core literacy level of mathematical abstraction.
