Getting the picture: The role of metaphors in teaching electronics theory

In this paper, I report my investigation of the use of metaphors in teaching theory in electronic engineering. I give a description of the nature of metaphors, how they are used in teaching the theory and some of the problems that might arise in the process. I investigate how some people react to the metaphors and how others forget the metaphors once they have learnt the theory. I suggest some reasons why this might happen.
