Hence the study was able to identify those underpinning science concepts which were well understood, and those which were not so well understood. The frequencies of several misconceptions, uncovered in earlier interviews and also included in the questionnaires, are also reported. It is suggested that both the basic explanations and the difficulties of unde...
