Lesson 4 Getting Started in Course Design
4-2 ADDIE vs SAM
While ADDIE is a functional, flexible, and common instructional design framework, it is also worthwhile to briefly discuss the Successive Approximation Model (SAM). We are using Michael Allen’s e-learning text and following the Savvy Start approach in our weeks 7 through 9 project design.
SAM has some wonderful strengths, particularly in time and cost savings when done appropriately. SAM was originally designed as an iterative model with a heavy emphasis on moving quickly to the rapid prototyping stage, as seen below.
Using Allen Interactive words, here is a more detailed description of Iterative Design and Development:
“At the core of our SAVVY Process is iterative design and development, also known as the Successive Approximation Model (SAM). When using this model, the key is to propose a series of candidate solutions, each one building on the preceding attempt, until the desired degree of accuracy is achieved to solve a problem.
Basically, successive approximation in e-learning design is a series of attempts to solve an instructional problem. In each iteration, we take what was discovered in any previous attempts, and further refine the design. By executing this model rapidly, using rough online prototypes, and avoiding the trap of getting buried in content detail too soon, we can easily correct mistakes.
The iterative design process provides a way to get the most effective design possible for you within the constraints of a real project.”
