Assignment 2

 As I read through this case study many evaluation models come to mind. I believe that the purpose of evaluating this program is to get feedback on the effectiveness and if it is meeting the intended goal-that being to prevent type 2 diabetes in pregnant Aboriginal women through exercise. Certainly some evaluation theories can be ruled out – Levine being one example.

I would use the Scriven model to evaluate this program. Obviously the purpose of the exercise program is very well intentioned and serves a definite need. Use of the Scriven model:

·         Would allow the evaluator to describe the goals of the program

·         The evaluator could look at the roles of those involved and the motivation to improve

·         Is set up well to give both formative and summative feedback.

In the Scriven model I believe it would be the formative and summative feedback given that is crucial to the program and its effectiveness.

I do believe that one could also utilize the Stake – Countenance model. As indicated above, the purpose of the program is very well intentioned, however those delivering the program would like to also measure the effectiveness of it as well as the participants in the program would also benefit from observing their fitness gains.

The Stake model allows for this as it provide a good description, however the judgement of the program and its effectiveness is the crucial feedback necessary. The Stake model also looks for congruence between what is intended and what is observed. This is critical and one of the main reasons for using the Stake model. This exercise program has an intended purpose and it is hoped that would be observed in the evaluation.  

In essence either of the two approaches would work in the evaluation of the program however I believe the better choice would be the use of the Stake - Countenance model due to what I would see as the logical connection between the event (exercise classes) and their intended purpose (prevention of Type 2 diabetes).
