I am enormously grateful to the readers of this journal for their kind attention to this work over the past 30 years. Conceptual analysis, the subject of my article, is primarily about clarifying meanings of those key concepts that are central to our collective work. Given the number of nebulous concepts in environmental education, and in education in general, this work has never ceased to be important — though, sadly, it is often neglected. Take, for example, a concept currently in vogue, social learning. Two ways of approaching this sometimes fuzzy concept would be, first, for authors to provide a clear articulation of the term, in their own view. What exactly does the idea of social learning involve for an author, and what are the implications for its use in the particular context in which it is used? This is a lot like clarifying one's own assumption about a concept for the benefit of the author and reader alike, and something we should be able to expect from all authors. Second, researchers can analyse the scope of a concept's usage within a body of literature, such as Rodela (2012) has done with social learning. This kind of analysis can provide a kind of heuristic for other researchers to navigate the extant usage of a key concept, and to point in future directions.
