The two models of instructional design I have chosen are ADDIE and UbD. UbD is essentially a streamlined version of ADDIE. All the elements of ADDIE are incorporated in UbD, the main difference is the planning stage is left to the end of the process after all the information needed for the plan is researched.
UbD starts with goals and desired results. This is addressed in ADDIE as well but comes after the discovery of prior knowledge and student needs.
Assessments are an integral part of the design in both models. ADDIE elaborates and defines this under several steps: Analysis, Design, and Development, whereas UbD streamlines this under the Determine Evidence step.
The models are very close and UbD uses the basic plan of ADDIE as the foundation of the model. UbD incorporates the exploration of a student’s prior knowledge and needs as an essential process for the design stage. UbD by definition is a backward design. The planning stage is left for last after the goals and assessments have been determined.
