Research On Teaching Strategies Of Mathematics Concepts In Senior Middle Schools Oriented To Cultivation Of Mathematics Abstract Literacy

With the continuous revision of "General High School Mathematics Curriculum Standards",the cultivation of abstract literacy in mathematics has gradually attracted people's attention."Abstract" activities are mainly at the stage of existence and concept formation,so mathematical concept teaching is an important part of cultivating mathematical abstract literacy.Educators continue to explore and try new teaching methods and strategies,combining the teaching of mathematical concepts with the cultivation of mathematical abstract literacy,and promote the development of students' abstract capacity.First,the thesis constructs the basic framework of teaching strategy research based on the theoretical research of mathematical concept teaching strategies and mathematical abstract literacy by consulting a large number of documents.According to "General High School Mathematics Curriculum Standards(2017)",the classification of high school mathematics knowledge,the teaching suggestions of mathematics abstract literacy,and the influencing factors of classroom effects will conduct preliminary analysis on the level of students' mathematics abstract literacy and the teaching situation of teachers.The status quo of the cultivation of abstract literacy of mathematics in concept teaching has found the following phenomena in the teaching of high school mathematics concepts: 1.Teachers do not set the teaching goals comprehensively;2.Teachers pay little attention to high school math concepts;3.Teachers' abstract literacy in mathematics The way of training is not clear;4,the teaching of concepts by teachers: emphasize understanding and neglect formation;5,the level of expression of students' abstract literacy ability is unevenly distributed.Secondly,the thesis integrates the phenomenon characteristics of mathematical concept teaching and mathematical abstract literacy.Starting from the four stages of teaching goals,introducing,forming and understanding mathematical concepts,it proposes a high school mathematical concept teaching strategy that points to the cultivation of mathematical abstract literacy: 1.Set teaching goals reasonably,Find the entry point of mathematical abstract literacy;second,carefully design the problem situation,grasp the entry point of mathematical abstract literacy;third,grasp the formation process of concepts as a whole,and promote the growth point of mathematical abstract literacy;fourth,deep integration of numbers and Shape,the growth point of the development of mathematical abstract literacy.Different from the traditional teaching strategy research in the past,the thesis incorporates modern information technology to transform the abstract concepts of mathematical abstract literacy into concrete and operational mathematical activities.Finally,according to the teaching strategy,a detailed teaching record of the "concept of derivative" is carried out to support the teaching strategy.
