| Abstract: | This paper describes an analogy classification framework used with high school chemistry textbooks. The framework takes into account aspects of past research into analogies in science education to allow for a systematic classification of textbook analogies based upon nine criteria including chemistry content area. Many of the 93 analogies classified described abstract chemistry concepts such as atomic structure and bonding, however, the frequent use of simple analogies, and the scarcity of stated limitations, are likely to create learning problems for students. In some textbooks, authors made use of margin spaces to include more analogies and these marginalised analogies often contained a pictorial component. Recommendations for further research into analogies in science education and possible methodological approaches are suggested. |
