Research On Teaching Strategies Of Large Units From The Perspective Of Core Literacy Of Mathematics

The Curriculum standards for compulsory education mathematics(2022 edition)specify that the basic direction of education reform is to implement core competencies,carry out large-unit teaching,multi-evaluate learning behaviors,and develop students’ necessary character and key abilities.In mathematics,teachers should form mathematics classroom to reflect the pursuit of value in the new era,advance the development and implementation of characteristic mathematics teaching strategies,and promote the rapid development of students’ mathematics vision,mathematics thinking and mathematics language.The traditional class-time teaching is carried out according to the arrangement of the knowledge of the textbook,and the emphasis is on the students’ mastery of the class-time knowledge,which is not beneficial to the students’ in-depth analysis of the core problems of the unit and the generation of the knowledge structure of the unit.The core of big unit teaching is unit theme,which links up the scattered teaching material knowledge and integrates to form the unit teaching content with clear knowledge characteristics and structure characteristics,so that students can understand the knowledge completely and systematically.How to carry on the big unit teaching also needs the thorough exploration research in the teaching practice.Based on this,this paper is mainly divided into the following four parts:The first part,through literature research,sifts out the existing research results that accord with the theme,studies comprehensively and conscientiously,looks for the research question,clarifies the research goal and the research content,form a rational understanding of the concept of large-unit teaching,find the internal elements of large-unit,analyze and construct the internal structure of large-unit.The second part,through the questionnaire survey,clarifies the present situation of large-unit teaching,summarizes and analyzes the existing problems and successful experience of large-unit teaching.The third part,through text analysis,it is clear that the open line in the teaching of the module of“Number and algebra” is the knowledge content,and the hidden line in the teaching is the mathematical thinking mode,selecting 13“Core concepts” to lead big unit teaching,refining the internal elements of big unit and clarifying the internal structure of Big Unit through teaching practice,the formation of pre-analysis,teaching design,classroom teaching,homework design and teaching evaluation of the unity of the large unit teaching strategy system.The fourth part presents the application of the series teaching strategy of the large-unit teaching,showing the whole picture of the large-unit teaching and the actual effect.
