Spiral curriculum

A spiral curriculum is an educational approach where key concepts are revisited and expanded upon over time. In the context of general knowledge, this means students learn a foundational idea at one level, and as they progress, they encounter that same idea again, but with deeper complexity and application. For example, students might learn basic geography in early grades, then explore it in more detail later with economic and cultural contexts. This method reinforces understanding, helps build connections between topics, and supports long-term retention of knowledge by revisiting themes as students mature.
