Joseph Schwab's 4 components

As I was browsing through "Evaluation Roots: Tracing Theorists' views and influences, I came across a passage on p.338 that talked about some ideas by a Joseph Schwab.

There are four commonplaces of a learning experience:

1. Teacher
2. Learner
3. Curriculum
4. Milieu or context

Fascinating! This is what I have found to be true also. The 3-person model is also founded on such ideas. Fascinating. I will have to read more on Joseph Schwab.
