A Study On The Teaching Design Of "Rectangular And Cube Volume" In Primary Mathematics Based On The Theory Of Change

Mathematics curriculum reform is the key to teacher’s classroom implementation, the teacher put mathematics curriculum concept effectively into classroom teaching behavior, promote the students’ learning, development, we can say that the curriculum reform can be effectively implemented. The of mathematics teachers, teaching organization and teaching design put forward new challenges and requirements, but also the development of curriculum reform and in-depth the key link, teachers are required to use new theory, methods of classroom teaching design constantly were optimized and improved.In view of this study based on variation theory, combined with characteristics of elementary school mathematics content, using the framework of Teacher Wang Guang ming seven teaching design, in order to the contents of the volume of the elementary school mathematics cuboids and cubes, for example, first, it analyzes the learning needs of students, further research research students and the teaching contents were analyzed, students understand the basic knowledge base and the volume of teaching in the design exist shortcomings. Then from on the design of teaching aim, teaching content design, teaching design and teaching evaluation design the four plates were specific teaching design, found variation theory to design of teaching aims in the basic procedures for the establishment of the class Goal. And according to the volume of teaching, use of the variation theory, establish the key features and design variation schema, knowledge from multiple dimensions to teach the students. From the introduction of teaching, the new grant, consolidate to summarize four blocks for the design of teaching process. And the use of the diagnostic evaluation, formation evaluation and development evaluation of a variety of evaluation methods, comprehensively and objectively to evaluate the teaching effect to carry on the evaluation design. Finally, put forward to develop the teaching goal, reasonable material organization, stimulates the student to study desire, guide the student to carry on the variation, to build a body of knowledge and control communication and so on reasonable suggestions.
