Answer to the question about "models and their role"

1.       What kind of models there was mentioned?

We have two kind of models:

-          Learners´ mental models are  they are internal representations and they are dynamic, recursive process of learning by constructing mental models of the phenomenon under study.

-          Hypermodels are are conceptual models realized as computer models embedded in interactive curricula. These are external representation and they support internal models.

2.       What ´s the role of these models in learning?

These models involve the formation, testing and subsequent of reinforcement, revision or rejection of mental models. Learner draws on a prior-knowledge and new information during model-formation to construct a mental model of some phenomenon.
