Often a real world process like the combustion engine does not allow for easy viewing of internal actions. Additionally, there is a level of danger involved with the close inspection of this action. VR models offer the ability to view any process clearly and without concern for personal safety. It is possible to view the teaching Avatar as a world. In a literal sense, the Avatar would be a large model surrounding the students.
Avatars can exist inside other Avatars.
In this environment, learning becomes an immersive process. This would be particularily helpful in dicussions about oceans, the cosmos, or any type of environment. To show more a practical example of this concept, we return to our earlier example of a combustion engine. It would be appropriate to show the model small and whole and allow the students to get an overview of the engine in relation to the automobile. In a very real sense, by virtue of scale alone, our model of the engine can become an entire world with its population on the inside.
