Critique of Quantitative Study ArticleThis article is a critique of an article written by McKinney and Jones (1993) entitled: “Effects of a Children's Book and a Book of traditional text on fifth grade student achievement and achievement “Attitudes toward Social Studies.” In their research, the authors examined the effects of a children's book and a traditional social studies textbook on knowledge acquisition and attitudes toward social studies and the textbook in a sample of 57 fifth graders. . It is the intention of this article to develop the analytical discussion and holistic interpretation of McKinney and Jones' (1993) quantitative study. Research Problem The purpose of the research was implicit in the introduction and clearly and succinctly stated as follows, “…examine the role of a children's book and a regular textbook on fifth grade students' knowledge acquisition elementary school and attitudes toward social studies and their textbooks” (McKinney & Jones, 1993, p. 91). The problem explicitly indicated the population studied (fifth grade students) and the experimental nature of the research as the independent variables were mentioned (the textbook and the children's book), the dependent variables (knowledge and attitudes towards social studies and their textbook), and their relationships (the effect of books on knowledge acquisition and attitudes). The authors defined both variables by providing an overview of the book and textbook and describing the tests and test items, however, more detailed information on the variables was needed to promote rigorous understanding of the authors' criterion in their selection. McKinney & Jones' (1993) six hypotheses are clearly stated in declarative form and expected differences between groups could be tested through... half of the paper... information about the American Revolution should be added.
