A Study of Middle School Geometry Teaching from the Perspective of Scaffolding Instruction

随着教育改革推进，在传统教学模式难以满足初中几何教学需求的情况下，支架式教学以学生为中心、强调自主探究与协作学习的特点，展现出其契合现代教学理念的优势。本研究以支架式教学的五大核心环节为脉络，借助“支架”这一工具，在建构主义理论框架下，基于初中几何《平行四边形的性质》教学设计并展开教学实践。研究结果表明，运用支架式教学助力学生基于现有认知水平跨越“最近发展区”，能够显著增强学生的课堂互动积极性与内在学习动机，进而促进学生自主学习能力、合作交流能力等综合能力的发展。With the advancement of education reform, in the case that the traditional teaching mode is difficult to meet the needs of junior high school geometry teaching, scaffolding teaching, which is student-centered and emphasizes on independent inquiry and collaborative learning, shows its advantages in line with the modern teaching concepts. This study takes the five core aspects of scaffolding teaching as a vein, and uses the tool of “scaffolding” to design and carry out the teaching practice based on the teaching of middle school geometry “Properties of Parallelograms” under the framework of constructivism theory. The results of the study show that scaffolding teaching helps students cross the “nearest developmental zone” based on their current cognitive level, which can significantly enhance students’ motivation in classroom interactions and learning, and then promote the development of students’ comprehensive abilities, such as independent learning ability, cooperative communication ability.
