Research On Junior High School Mathematical Scaffolding Teaching Design Based On Core Literacy

The core literacy points out the development direction for the curriculum reform.At the same time,the core literacy of mathematics provides a good answer to the question of what kind of mathematics quality should be cultivated in mathematics education.The core literacy of mathematics is the concentrated expression of the goals of mathematics curriculum.How teachers should cultivate students’ mathematics core literacy through teaching has become the focus of current educators’ research.Instructional design is the grand plan and blueprint of classroom teaching,which is the premise and important basis for achieving the curriculum objectives.Therefore,the appropriateness of teaching design directly determines the direction of classroom teaching.Due to the existence of old teaching concepts,teaching methods and methods,the cultivation of students’ core literacy is seriously hindered.This paper studies under the background of such teaching.Firstly,this paper consults a large number of literature,and makes a detailed analysis and research on the related concepts and theoretical issues of core literacy,mathematical core literacy,teaching design and scaffolding teaching.Secondly,90 teachers and 325 students from four typical junior high schools in Xingren County were investigated by questionnaire.This paper combines the results of the questionnaire survey with what we have heard and seen in the three-year front-line teaching,and draws the following typical problems: 1.low emphasis on teaching design;2.single teaching evaluation mode,lack of feedback and evaluation in classroom teaching;3.dull classroom,low participation of students;4.over-emphasis on teaching results,ignoring the cultivation of students’ abilities.Thirdly,according to the present situation of mathematics teaching in junior middle school,this paper tries to concretize the core literacy and integrate the cultivation of core literacy into the Scaffolding Teaching mode.In the Scaffolding Teaching design,the core literacy is concretized into the cultivation of students’ abilities of expression,calculation,thinking and model thinking.It puts forward the principles of Scaffolding Teaching under core literacy: student-centered principle,problem-centered principle and situation-based principle;and the Scaffolding Teaching Strategy under core literacy: making rational use of the latest development zone in mathematics teaching;attaching importance to scaffolding construction;and creating a challenging teaching environment.Finally,through specific cases of mathematical scaffolding instructional design,the theory and practice are organically combined,which further proves the practicability of the research on core literacy-based scaffolding instructional design.
