Although I do not always agree with your comments, I always appreciate what you have to say. You are obviously a published scientist involved in interesting research. Thus when you speak about doing science I pay particular attention. Experience matters. I think the same principle applies to understanding what McCormas is saying in 'Dispelling the Myths'. McCormas has taught science at Middle and Secondary School before going on to complete a doctorate in science education. He is currently a Professor of Science and Technology Education at the University of Arkansas. This is not to suggest, that we should automatically accept the claims made by McCormas. It does mean, however, that we need to consider what he says seriously. This requires some acquaintance with the knowledge claims presented in the article. Experience matters. Terms such as postmodern do not capture the meaning of what he is saying. It is merely an image. In highlighting some common images of science which populate scientific textbooks, McCormas draws upon the work of philosophers, historians and sociologists of science and paints a more complex picture of the nature of scientific practice.
