Research On Teaching Design Of "Graphics And Geometry" In Primary School Mathematics Based On Students’ Development Core Literacy

"Graphics and geometry" is one of the four modules of primary school mathematics teaching content.The mathematics curriculum standard of compulsory education(2011Edition)clearly points out that the teaching goal of "graphics and geometry" should cultivate students’ spatial concept,geometric intuition and reasoning ability,which is also the necessary literacy of students specified in the core literacy of Chinese students’ development.Therefore,the teaching design of "graphics and geometry" in primary school mathematics should point to the cultivation of core literacy,so that the core literacy can be truly implemented in primary school mathematics teaching.This study uses the literature research method to sort out the literature related to core literacy and instructional design.On this basis,it uses the methods of questionnaire and interview to carry out the survey and research design,and explore the practical difficulties of primary school mathematics "graphics and geometry" instructional design under the background of core literacy.The current situation of front-line teachers’ teaching design is mainly as follows: the teaching goal design adheres to the "three-dimensional goal" mode,focuses on the "knowledge-based" goal,lacks the requirements of "necessary character",and is divorced from the requirements of students’ development of core literacy;The teaching content design pays too much attention to the subject knowledge standard,ignores the students’ real life situation,and lacks the culture of "graphics and geometry",which is difficult to improve the students’ core quality of development;The teaching process design ignores students’ active participation in exploration,students’ perception of on-site experience and the cultivation of "necessary character",which fails to show the connotation of students’ development core quality.Based on the analysis of practical problems,this study puts forward some suggestions on the teaching design of "graphics and geometry" in primary school mathematics under the background of students’ development of core literacy: first,the theoretical level: strengthen the theoretical learning of core literacy and change the teaching concept;Strengthen the study of instructional design theory and improve the ability of instructional design;Strengthen the study of the mathematics text of the primary school and grasp the design intention of the text;The second is the design level:strengthen the research on primary school mathematics teaching design,improve the ability of teaching design,and put forward corresponding design principles and strategic suggestions from the five design dimensions of teaching objectives,teaching contents,teaching process,teaching methods and teaching evaluation.
