ADDIE follows a linear, systematic process with clear phases, while ASSURE is more focused on integrating technology and active learner participation throughout the design process. UbD, on the other hand, emphasizes backward design by starting with desired learning outcomes and then planning assessments and instruction to achieve those goals. One main difference is that ADDIE and ASSURE are more process-oriented, guiding the development step-by-step, whereas UbD is goal-oriented, emphasizing understanding and meaningful learning. UbD is often considered highly effective for curriculum planning focused on deep understanding, making it a popular choice for long-term educational goals.
