As a student learning how to design teaching materials, using the Successive Approximation Model (SAM) is flexible and encourages feedback throughout the design process. It breaks the process into three stages (prototype, iterative design, and final review) and works through each one with a clear plan. This is important for communicating with other designers and stakeholders, making sure everyone agrees on what is being done. With SAM, I can work with other people and experts to make improvements all the way through the process. This lets us make sure that learners get the best possible experience.
