ADDIE Model

ADDIE

I remember learning about ADDIE in the EdTech 503, Instructional Design, and the evaluation component was easily understood within the whole ADDIE cycle.  As an educator, my mind is already trained to see evaluation as a component of instruction.  Now that I’m taking EdTech 505, Evaluation, that component has become harder to grasp.  I feel like I have been trying to cut out the piece of the pie called “Evaluate” to see if it tastes different from the rest of the pie.  In other words, even though the pie does have separate pieces, it is all made from the same ingredients; one piece cannot be completely independent from the others.

The ABCs of Evaluation, p.51

Evaluation: Program Cycle

This model does not stray much from the ADDIE model, but you can make the distinction with the purpose of the model.  ADDIE relates more specifically to instructional design, whereas the Program cycle on the right can relate to instruction or any active part of a system or organization, whether it relates to instruction or not.  This model does account for both formative evaluation and summative evaluation, which the ADDIE models does not distinguish.  Also, this model suggest that implementation strategies can change according to the formative evaluation during one rotation of the cycle.

The Planning-Evaluation Cycle

The Planning-Evaluation Cycle

This model does not fit as easily into an educational or instructional situation.  Even though the components of ADDIE and the Program Cycle appear in this model, it is distributed quite differently from the other two models.  For example, this cycle includes analysis and design as part of the evaluation phase.  Nor, does this model clearly distinguish between formative and summative evaluation, it almost suggest that the whole evaluation process is formative.  It appears that this model would be good to analyze some function or feature of an established system, and based on the results in the evaluation phase, the ADDIE model could be applied as an instructional model within the planning phase, which would address the needs that were discovered during the evaluation phases.
