How does the Successive Approximation Model (SAM) differ from the Understanding by Design (UbD) approach?

The Successive Approximation Model (SAM) emphasizes feedback and iterative prototype improvement as its central tenet. This approach is designed around the idea that by creating and refining prototypes through repeated cycles of development and testing, designers can effectively enhance the learning experience. This iterative process allows for ongoing assessment and adjustments based on feedback from stakeholders, learners, and data.

In contrast, the Understanding by Design (UbD) framework is more focused on identifying desired learning outcomes at the beginning of the design process and then working backward to create assessments and instructional strategies that will help achieve those outcomes. While both models aim to create effective learning experiences, SAM’s strength lies in its flexibility and focus on continuous improvement, which contrasts with the more structured approach of UbD that is centered around predetermined goals. The emphasis on feedback in SAM enables a dynamic response to learner needs, whereas UbD is more about aligning the design directly with specified objectives from the outset.
