In this assignment I compared the ADDIE (Analysis, Design, Development, Implementation, Evaluation) and PIE (Plan, Implement, Evaluate) instructional design models. I gained valuable insights into the diverse approaches to designing effective learning experiences. The assignment not only facilitated a deeper understanding of these models but also underscored the importance of selecting the most appropriate model for specific instructional design scenarios. Comparing the ADDIE and PIE models revealed distinct differences in their methodologies and emphases, with ADDIE offering a structured approach and PIE emphasizing flexibility and adaptability. Moreover, the assignment prompted me to recognize that the effectiveness of instructional design models hinges on their alignment with the specific needs and constraints of a given learning context, while also providing practical experience in crafting clear and measurable learning objectives using the ABCD (Audience, Behavior, Condition, Degree) model.
