Research On Teaching Design Of Mathematics Cuboid Cognition In Primary School Based On APOS Theory

Primary school mathematics teaching design is a specific design that can effectively handle "teaching" and "learning" in the teaching system,mainly to quickly and effectively improve students' learning efficiency.Teaching design is the "blueprint" of classroom teaching,and it is also the foundation of classroom teaching.A good teaching design can effectively improve students' learning and even promote their all-round development.When designing primary school mathematics teaching,it is necessary to follow the rules,study and analyze all possible problems in the teaching process,and design methods that can effectively deal with the problems.Based on this,it can be said that it is an art and an important part of teachers.Demonstration of teaching skills.In addition to this curriculum standard,it is also pointed out that the teaching goal is derived from the curriculum standard,and the earliest appearance is not the teaching design,but the evaluation design,and its ultimate direction is the quality of students' learning results.Therefore,the thesis takes the APOS theory as the support point.On the one hand,combined with the characteristics of primary school mathematics content,it adopts the framework of teacher Wang Guangming's seven-link teaching design.Carry out classroom teaching design."Understanding of cuboid" is an important part of the cognition of "graphics and geometry".Planar figures are two-dimensional,and geometric figures are three-dimensional,that is,three-dimensional figures.Through the transformation from two-dimensional space to three-dimensional space,students can further help students The establishment of the concept of geometric space is a turning point for students to learn,and it needs to be cultivated gradually.In teaching design,it is generally necessary to carry out the necessary preliminary analysis from the perspective of the learner.Through certain research methods,such as questionnaires,a preliminary understanding of the students' learning level is obtained.At the same time,according to the curriculum standards and in-depth analysis of the content of the textbook.After laying a good foundation,according to the APOS theory and the preliminary concept of teaching design,a preliminary teaching design is completed and finally implemented.According to the actual situation of classroom teaching and continuous practice,it is not difficult to see that the teaching design based on APOS theory can allow students to better understand mathematical knowledge,and also allow students to better apply knowledge to real life.Improve the ability to solve practical problems.Finally,from the cooperation and communication between teachers and students,pay attention to whether students internalize their own classroom research,and timely carry out group cooperation learning division of labor and operation guidance for students,so as to improve the effectiveness of group cooperation.
