What are the molecules doing?


J.D. Bradley

Abstract

Johnstone’s identification of teaching and learning difficulties derived from the three levels of description in chemistry is well-known and much debated, but effective responses are still needed. It is suggested that a macro-micro dictionary could help. The dictionary concept is exemplified and its potential value in dealing with the difficulties associated with two of the levels explained.
