The SAM Model, or Successive Approximation Model, is an instructional design framework that emphasizes iterative development. It focuses on creating learning experiences through repeated cycles of design, development, and evaluation. This approach allows designers to refine their materials based on feedback, ensuring that the final product meets the needs of learners effectively. In the SAM Model, the process typically involves three main phases: preparation, iterative design, and implementation. During preparation, designers gather information and set goals. The iterative design phase includes creating prototypes and testing them, while implementation involves delivering the final product. This model promotes flexibility and responsiveness in educational design.
