Play around with the ideas and see where you get to. Chew over the information until you've digested the ideas . Spend some time considering this and it will all become clear. You'll need to dig below the surface to get the nub of the issue. Metaphors embody and define the intangible and abstract, but this process inevitably constrains perceptions and actions to those which make sense within the logic of the metaphor.
Metaphors are therefore both descriptive and prescriptive.
As students become aware of their own metaphors for learning they can recognise how these limit or liberate them. It also pays to know your own preferred metaphors because they have such an influence on the way you teach. Once you are familiar with your preferences you can begin to stretch yourself by employing new metaphors. In addition to teaching the subject matter you will be training your students to process information via a variety of metaphors. The result will be an enhanced ability to think more creatively.
