It's possible that:
* You meant a different name or term: Maybe there's a slight misspelling or a different name entirely that you're thinking of.
* It's a specific model within a certain context: Perhaps this model is used in a specific school, organization, or community.
To help me understand what you're looking for, please provide more information, such as:
* Where did you hear about this model?
* What is the context?
* What are some key features or concepts you remember about it?
Once I have more context, I'll be able to give you a more relevant answer.
