  • 3 Key Principles of the Spiral Curriculum (Bruner), Explained!

    The spiral approach to curriculum design reminds us that courses are not singular, set-in-stone units of work. Each course or unit of work that we cover builds upon something previously. This approach forces us to work with our colleagues who were a childs teacher in a previous year or in years to come to develop a cohesive approach to teaching.
