Instructional Systems Design Model  (Based on Cognitive Psychology)

Instructional Systems Design (ISD) is a philosophy, discipline, and systematic process used for creating instruction to optimize learning.  Its purpose is to define what is to be learned, plan interventions that will facilitate the phenomenon of  learning, measure learning to determine how well performance objectives were met, and refine learning parameters until learning or performance objectives are met.  

A generic ISD model (ADDIE), having five phases, is typically used to create knowledge or skills lessons for the various types of training such as paper-based or traditional Instructor-led education or training, in addition to Computer-Based Training (CBT).  ADDIE is the acronym for the Analysis, Design, Development, Implementation, and Evaluation phases of the model.  Phases of the ADDIE model are shown on the menu above, and are further described below:

ISD is an iterative process; there is continual feedback between the phases to accommodate revision and refinements of the instruction.
