These paradigms are examined in terms of past trends in science education research, indicating that over the last several decades a shift in approach from the quantitative to qualitative has occurred. The central thesis of the essay contends that methodological decisions should be based in pragmatism, rather than a pre-existent set of philosophies or beliefs irrespective of context.
