大单元视域下小学数学CTI教学模式的优化设计研究

The Research on the Optimized Design of CTI Teaching Model in Primary School Mathematics under the Perspective of Large Units

摘要: CTI教学模式与大单元理念均指向核心素养的发展，二者具有内在契合性。将CTI教学模式与大单元教学有机融合，能够有助于缓解知识割裂、思维固化等问题，培养学生的迁移与创新能力，提升数学思维。本文以“比例的基本性质”为例，在大单元视域下，通过以大概念引领知识探究与建构、以关键问题深化知识理解、以结构化迁移促进知识迁移、以个性化探究拓展知识创新，对CTI模式进行了适合小学生认知的优化，旨在为一线教师提供可操作的教学范式。

Abstract: The CTI teaching model and the concept of large units both aim at the development of core competencies and have an inherent compatibility. Mutually fusing the CTI teaching model with large-unit instruction can effectively address issues such as fragmented knowledge and Rigid thinking, thereby fostering students’ abilities in transfer and innovation while enhancing mathematical thinking. Taking “The Fundamental Properties of Proportions” as an example, this study explores the optimization of the CTI model within the perspective of large-unit instruction. Specifically, the optimization includes: guiding knowledge exploration and construction through Broad Concept, deepening understanding and application through key problem-based tasks, promoting knowledge transfer through structured transfer tasks, and extending innovative application through personalized inquiry tasks. The optimized CTI model is designed to align with primary school students’ cognitive characteristics and aims to provide frontline teachers with an operable instructional framework.
