深度学习视域下的中职数学问题串教学策略研究

Research on Teaching Strategies of Problem Chain in Secondary Vocational Mathematics from the Perspective of Deep Learning

摘要: 问题串是具有逻辑性和层次性的递进式的问题体系，深度学习是以知识的内化理解和灵活应用为核心的高阶学习模式。针对中职学生数学基础薄弱、学习兴趣欠缺、抽象思维不足等学情，开展深度学习视域下的问题串教学能够引导学生主动探究、自主建构知识体系，并依托生活和专业情境有效解决学用脱节的问题。本文结合中职数学的学科特点，确立了核心素养导向、贴合认知规律、依托专业情境、遵循知识逻辑的四大设计原则，梳理了知识建构类、启发探究类、实践建模类、拓展迁移类四类教学策略，助力学生深度学习，实现知识、能力和素养的全方位发展。

Abstract: A problem chain refers to a progressive question system with logicality and hierarchy. Deep learning is a high-level learning mode centered on knowledge internalization, comprehension and flexible application. Given that students in secondary vocational schools generally have weak mathematical foundations, low learning motivation and insufficient abstract thinking ability, the implementation of problem chain teaching from the perspective of deep learning can guide students to explore actively and construct knowledge systems independently. Combined with real-life and professional scenarios, it also effectively bridges the gap between theoretical learning and practical application. In view of the disciplinary characteristics of secondary vocational mathematics, this paper puts forward four design principles: competency-oriented development, compliance with cognitive rules, integration with professional scenarios and adherence to the inherent logic of knowledge. It also summarizes four types of teaching strategies, namely knowledge construction, inquiry enlightenment, practical modeling and expansion and transfer. The research aims to facilitate students’ deep learning and promote their all-round development in knowledge, ability and comprehensive literacy.
