This volume is the second of a two-volume series which surveys the extent to which sex, race, and class bias can be found in commonly used elementary-level instructional materials in Manitoba, Canada. Analysis of materials used in grades four through six indicates that the negative biases present in the kindergarten through grade three materials (the focus of the first volume) recur and in fact increase in number and subtlety as children are exposed to a greater variety of learning resources and to more complex concepts. Primarily, the volume is devoted to the evaluation of approved texts for language arts and social studies; however, texts in the areas of mathematics and science are analyzed, and recommendations for nonsexist practices in the areas of health and physical education are made. Concluding sections offer guidelines for eliminating sexism; a brief list of strategies for changing race, class, and sex bias in informal and formal school contexts, among parents, and in the community; an annotated bibliography of non-biased books; a thematic bibliography; and an annotated bibliography of texts that were found to present positive images of real and fictional characters.
