Study On Core Concepts Cohesion Of Elementary Mechanics Based On Learning Progression

Learning progression research is one of the hot spots in international education research,and plays an increasingly important and positive role in the promulgation of educational policy documents as well as specific curriculum and teaching practice reforms in various countries.China’s curriculum reform is in line with the direction of international science education,and in the case of the physics curriculum,it focuses more on student development,cultivating students’ subject core literacy and teaching around core physics concepts.For students,in the specific content,we should combine science in primary school with physics in middle school and to construct a progressive teaching model for learning core concepts corresponding to specific teaching content in curriculum learning.In this study,we identified the core concept of "friction" under the theme of "mechanical motion and force" as a step-by-step study from a practical education issues.This paper is an advanced study of the core concepts of mechanics,divided into the following four stages.Review the literature to complete theoretical basis for research.Comparative study of mechanics teaching content,specifically analyze the course standards and teaching materials of friction and elasticity teaching content,find out the span between knowledge.It provides the rationale for determining advanced levels and endpoints.Build the core concepts of "friction" and "elasticity" to learn advanced,design teaching activities and apply them to teaching practice.Through the questionnaire survey of students,the results of special tests were analyzed,and the implementation of elementary mechanics bridging teaching based on advanced learning theory was analyzed.The results show that the teaching based on the learning progression theory is superior to the traditional teaching mode,and the application of the learning progression theory in teaching can help students integrate fragmented knowledge and provide important reference for teachers to adjust their teaching plan,design and cognitive development of students are consistent with each other.
