Which curriculum model emphasizes cyclical evaluation and revision?

The curriculum model that emphasizes cyclical evaluation and revision is the Taba Model. Hilda Taba's Grassroots Model is known for its inductive approach, starting with specific content and moving to general principles. A key characteristic is its iterative and cyclical nature, where evaluation is not merely a final step but an ongoing process that feeds back into the earlier stages of curriculum development. This continuous feedback loop allows for constant refinement and improvement.

• The Tyler Model is a linear, objective-driven model, focusing on four fundamental questions but less explicitly on cyclical revision.
• The Walker Model describes curriculum development as a complex, interactive process of deliberation, but it doesn't emphasize a formal cyclical evaluation and revision structure as prominently as Taba's.
• The Kerr Model also focuses on objectives, content, learning experiences, and evaluation, similar to Tyler, but does not highlight the cyclical, iterative revision process as a central tenet like Taba's.
