The Successive Approximation Model (SAM) is an innovative approach to instructional design, particularly in online learning. Developed by Allen Interactions, SAM offers a more agile alternative to traditional models like ADDIE, enabling designers to create practical, engaging learning experiences in a streamlined manner. The model addresses common instructional design challenges such as meeting timelines, staying on budget, and collaborating with Subject Matter Experts (SMEs) through an iterative process.
SAM focuses on a few critical steps repeated as often as necessary to achieve optimal learning outcomes. This flexible and iterative design process allows instructional designers to adapt and adjust their courses quickly as they gather feedback and insights from learners and SMEs. By using SAM, online course creators can save time and resources and deliver high-quality, impactful learning experiences for their target audience.
As online learning continues to grow in popularity, educators and organizations can significantly benefit from incorporating the SAM model into their instructional design practices. The SAM model consists of a preparation phase in which the instructional design team gathers resources and researches the needs of the learners. Then, the team moves through a series of iterative design and development steps to create a compelling and engaging online course.
