A Study On Primary School Expansion Mathematics Class Design

Primary school expansion mathematics class teaching is one of the most important achievements of the compulsory education reform.It is also an important complement to the traditional class teaching.An effective expansion mathematics class teaching can improve students' comprehensive quality,increase the interest on math learning,expand the mathematical thinking and train students' mathematics literacy.Although there are so many advantages of expansion mathematics class teaching,it is hard for teachers to design an effective class teaching due to its diversity,flexibility.So it will be of great use to have a study on primary school expansion mathematics class teaching.Focusing on the primary school expansion mathematics class design,this article mainly talks about the following three issues:(1)what are the features of the expansion mathematics class design and how many parts should be considered when design a class;(2)how to evaluate the effectiveness of an expansion mathematics class design;(3)for the same teaching content,how to improve the class teaching's efficiency.The basic implementation steps of the study can be summarized in the following four stages.First of all,some related literature was reviewed,the relevant theoretical concepts are clear,and the design and implementation methods of the existing primary mathematics teaching are studied.Secondly,based on literature,we analyzed the teaching design elements of primary expansion mathematics class.Thirdly,combined with the classroom teaching objectives of primary school expansion mathematics class,this paper proposes a mechanism to assess the effectiveness of classroom teaching's teaching effects in combination with learning test,questionnaire assessment and teaching seminar.Afterwards,an iterative improvement method for teaching design of expansion mathematics class based on teaching diagnosis was designed.Finally,taking the teaching content of “Irregular Figure Area Estimation " as an example,the teaching practice in D primary school is completed and the problems existing in practice are analyzed.Based on the above research,this paper has obtained the following three conclusions:(1)The design of primary expansion mathematics class can be mainly divided into four aspects: student's class participation,teaching content expansion,teaching content development depth and classroom teaching expression.(2)Integrating the form of education test,questionnaire assessment,teaching seminars and classroom observations in the form of teaching diagnosis can evaluate the effectiveness of primary expansion mathematics class teaching.(3)When designing a primary expansion mathematics class,making full use of the teaching diagnosis will be really helpful.
