The Study Of Mathematical Multi-representations And Teaching Scaffolding In The Smart-classroom Environment

Along with the new curriculum reform,information technology has an important impact on the classroom teaching.Smart-classroom comes into being in the age of high-speed development of information technology.It can create diversified and intelligent classroom teaching environment,which can effectively assist classroom teaching.Rain classroom as one of the Smart-classroom teaching platforms,combines with the functions of PowerPoint and WeChat platform.It can facilitate teachers to understand the learning dynamics of students and pay attention to each student's classroom participation and learning effect.This paper studies the concept and related theories of the Smart-classroom,Mathematical Multi-representations and teaching scaffolding.On the basis of studying domestic and foreign literature,this paper disusses the characteristics of Smart-classroom,the construction principle of teaching scaffolding and the internal and external transformation of the Mathematical Multi-representations.On the Smart-classroom teaching platform,the teaching model is established to promote the transformation of Mathematical Multi-representations by constructing mathematical teaching scaffolding.The model can mobilize students' multi-sensory cognitive factor.It can combine with the diversity of mathematical learning objects to represent and promote students' understanding of mathematical knowledge.This is also the innovation.In this study,the teaching model was applied to the concrete teaching practice.By constructing the teaching preparation scaffolding,the teaching situation scaffolding,the numerical combination scaffolding,the thinking map scaffolding,the cooperative activity scaffolding and the mathematical problem scaffolding in the Rain classroom teaching platform,which can promote the internal and external transformation of Mathematical Multi-representations and effectively assist classroom teaching.This paper carries on the research through the literature research method,the experiment research method,the questionnaire survey method and the interview method.Then it carries on the concrete teaching case,through classroom observation to understand the situation of classroom teaching and the learning effect of students.After the experiment,collecting the data,which is used to compare and analyse.Based on teacher-student interviews and teacher questionnaires,the following preliminary conclusions are drawn:this paper mainly constructs the teaching model in the Smart-classroom environment.It is found that the model is helpful to the internal and external transformation of students' Mathematical Multi-representations and promote the significance of the students' study.Through the teacher-student interview questionnaire analysis,it is found that the teaching model can improve thestudents' participation in the classroom and increase the students' interest in mathematics learning.It can also be used as a reference for teachers' teaching.However,as the study is still in the initial stage,the teaching practice of this teaching model in the Smart-classroom environment needs to continue to be studied and perfected,and the multi-function of the Smart-classroom platform needs to continue to be explored.
