Science communication teaching is a growing area in the UK, and a recent conference brought together teachers of existing and proposed courses to share information and experience. Their courses were of several types, from purely media skills courses for working scientists to theoretical and academic courses for undergraduate and postgraduate students in science, science studies and journalism. The conference stressed the value of skills but also of a theoretical background, and delegates welcomed contributions from fields such as the sociology of scientific knowledge and cognitive psychology. The conference established an electronic network, and formed a committee to maintain the group's interest and activities in the development of course materials and curricula.
This paper argues that explanation is central to much science communication and seeks ways of describing explanation through text as it is achieved in popular science writing. It is suggested that a framework elaborated by Ogborn et al. (1996) for analyzing the explanatory performance of science teachers in the classroom may be adapted for analysis of popular texts. The suggestion is elaborated through an extended case study of popular works on superstring theory, notably Brian Greene’s The Elegant Universe (2000). It is concluded that Ogborn’s scheme is useful, but the demands of this theory expose some of the limitations of the framework, and perhaps of textual— that is, non-mathematical—explanation in general.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
