Research On Teaching Practice Of High School Solid Geometry Concept Based On APOS Theory

Mathematical concepts are the basis of students’ cognition,the starting point of mathematics learning,and play an important role in mathematics learning and teaching.As a compulsory content in high school mathematics,solid geometry has many concepts and is closely related.Under the traditional teaching mode The teaching effect of the concept of solid geometry can be seen,which leads to many difficulties in the process of students learning solid geometry,and it is difficult to improve their spatial imagination.teaching effect.The research of the paper adopts the method of literature research and survey research.First,the relevant literature on APOS theory and the concept teaching of solid geometry is consulted,and then a questionnaire is used to investigate the learning status of solid geometry of a high school student and the teaching situation of teachers,and randomly selected Some teachers conduct interviews to understand their views on the teaching of solid geometry concepts and APOS theory,and conduct a comprehensive analysis of the survey results.Then,based on APOS theory and the results of the survey,the teaching design of solid geometry concepts and examples are given,and APOS theory is applied In the actual teaching and compared with the traditional teaching mode.After the research of the paper,the following conclusions are drawn:（1）The teaching of solid geometry concepts in high school has problems such as lack of students’ interest,lack of spatial imagination,and traditional single teaching methods.（2）The advantages of APOS theory as a concept learning theory It combines the two concept acquisition methods of concept formation and concept assimilation to better help students acquire concepts.（3）Compared with the traditional teaching mode,the solid geometry concept teaching under the guidance of APOS theory can improve students’ enthusiasm for learning,thereby further improving Students’ academic performance.In addition,the researchers also found some shortcomings of the APOS theory,such as higher requirements for teachers,more time-consuming and laborintensive than traditional teaching,etc.The researchers hope to provide the concept teaching of solid geometry through the research of the paper.At the same time,the APOS theory still has great research potential.It is hoped that more and more education practitioners can pay attention to this theory and try to apply it to teaching,replacing traditional teaching and better implementing the requirements of the new curriculum standards.
