I wish to call attention to what I consider to be extremely serious misrepresentations of the facts in a review article that recently appeared in this journal (Nagy & Griffiths, 1982). Not only are facts misrepresented, but the review demonstrates serious limitations in its treatment of several critical methodological and theoretical issues as well. First, I will elaborate on the misrepresentations of the facts. Then, for those who are interested, I will discuss limitations of their treatment of important methodological and theoretical issues in a companion rebuttal. As my work was most heavily misrepresented and criticized, I will generally limit my remarks to its treatment by Nagy and Griffiths. It should be noted, however, that other researchers received extensive and, in my judgment, unjustified criticism as well.
Factual Misrepresentation OneIn discussing a study by Lawson and Renner (1975), which examined the relationship between developmental level and the understanding of science concepts classified as concrete and formal, Nagy and Griffiths quote the following findings from page 352 of the Lawson and Renner report:Concrete-operational subjects are unable to develop understanding of formal concepts. Also, support is demonstrated for the other major premises of the study: concrete-operational subjects are able to demonstrate understanding of concrete concepts, and formal-operational subjects are able to demonstrate understanding of both concrete and formal concepts, (p. 542) Nagy and Griffiths then comment on these findings in the following way:Two aspects of these findings merit comment. First, the results do not show that concrete subjects are unable to develop understanding of formal concepts, but merely that in this study they did not. (p. 542) I will not comment on the second aspect of their comment in that the misrepresentation has already been made and the second comment merely represents opinion, not criticism. Note that Lawson and Renner are being accused of overgeneralization from their data. The statement that "Concrete-operational subjects are unable to develop understanding of formal concepts" is a strong one. Surely Nagy and Griffiths are correct that the study merely showed that the concrete 133 at NORTH DAKOTA STATE UNIV LIB on May 29, 2015 http://rer.aera.net Downloaded from
