Research On Teaching Design Of Plane Geometry Unit Based On ADDIE Model

The national medium and long-term education reform and development plan outline emphasizes that teaching should optimize knowledge structure,strengthen ability cultivation,and enrich social practice activities.At the same time,the 2022 edition of the compulsory education mathematics curriculum standard clearly points out that the previous classroom teaching unit should be transformed and the whole unit teaching should be promoted.As the mainstream of the future development of basic education,the organic combination of unit teaching and ADDIE model can break the defects of the small-class teaching model that emphasizes teaching materials but not students,use the global thinking to master the teaching content,promote classroom reform,and promote the development of students’ thoughts,emotions,attitudes and values.Based on the above facts,this study is based on the ADDIE model to construct a unit teaching design for junior high school plane geometry,aiming to provide reference for front-line mathematics teachers to carry out systematic design and implementation of unit teaching in teaching theory and practice.This study firstly elaborates the background and significance of the study,the connotation and characteristics of the main concepts in the study,the main theories applied,and provides a detailed combative review of the current situation of ADDIE model and unit teaching at home and abroad.The second part analyzes the correlation between the ADDIE model and the unit teaching design,and finds that the teaching objectives of both are consistent,the core concepts are unified,the unit teaching follows the steps of the ADDIE model,and the ADDIE model positively affects the unit teaching in turn.The third part uses questionnaires and questionnaires to investigate the development of mathematics.The third part investigates the current situation of plane geometry teaching in junior high school by using questionnaires and interviews,and summarizes and analyzes the existing problems in plane geometry teaching: teachers lack a correct view of geometry;teaching ignores students’ main position;teachers lack knowledge of unit teaching;students’ low interest in learning and poor attitude,etc.The fourth part is based on the ADDIE model for the teaching design of plane geometry unit,and "triangle" and "parallelogram" are selected as the teaching cases of the unit."The fourth part of the study is based on the ADDIE model for teaching the unit of plane geometry.The combination of the two is more likely to bring out the advantages of teaching as a whole,and to a certain extent can expand the teaching vision and improve the teaching efficiency.
