A Case Study Of Students' Participation Behaviour In Mathematics Expansion Curriculum Classroom In Junior Middle School

In order to advance the curriculum reform and optimize the curriculum system,the school regards enrichment curriculum as an important parts of curriculum construction.As the main body of classroom teaching,the teaching effect is greatly influenced by students,their behavior can reflect the degree of students' classroom participation and the characteristics of teachers' teaching.Therefore,based on the student's perspective,a literature analysis method is adopted to construct a research framework.We use “field lectures-classroom videos-textual recordings-teaching behavior coding-case studies of students' participation behavior in enrichment curriculum-inductive characteristics-teaching strategies ” as the research process.We select two sections of mathematical experiment and inquiry lessons,life mathematics and applied lessons,mathematical thought and method enrichment lessons,and summarize the twelve kinds of student participation behaviors,encode and statistics them,use quantitative and qualitative methods.Basing on the common features of students' participation behavior,response type and participation type,we obtain the characteristics of students' participation behaviors of expert teachers' mathematical enrichment classroom,and provide corresponding strategies for improving students' classroom participation.According to the results of the study,the characteristics of students' participation behaviors in the mathematics enrichment curriculum of expert teachers are obtained:Students take active actions such as show on stage,raise their hands to answer,etc;The time allocation,participation behavior,response behavior,response cognition,and teacher-student response methods of each teaching link are inconsistent;Students have more time and opportunities for independent thinking and cooperative discussion;When students think independently or communicate and discuss,they have a high number of high cognitive responses;In a relaxed and pleasant classroom atmosphere,students participate in various forms.According to the characteristics of participation,the following strategies are proposed: considering comprehensively of goals,activities and other aspects toincrease students' confidence in class participation;basing on context and content to choose multiple forms of participation,so that students can integrate into the classroom;Providing sufficient thinking opportunities to cultivate students' independent mathematical thinking;Improve students' learning ability by changing the way of learning;create a fun classroom atmosphere with the help of math culture and attract students' attention.
