Tóm tắt

In the context of digital transformation, the integration of technology into teaching should go beyond visual illustration and be organized as systems of cognitive support. This article examines the application of digital scaffolding strategies in teaching the topic “Derivative Applications for Function Analysis and Graphing” at high schools through theoretical analysis and synthesis. By clarifying the concept and characteristics of digital scaffolding, the study proposes a set of principles and a structured five-step pedagogical process for teaching this topic. The feasibility of the process is illustrated in detail through a typical teaching situation associated with a real-world profit optimization problem. The analysis shows that digital scaffolding strategies play an important role in structuring learning barriers, helping students not only overcome the cognitive difficulties specific to the topic but also to promote the development of  functional thinking, self-study competence, and mathematical modeling competence.
