To determine whether the distribution of male and female main character roles (sex dominance) differed significantly in the 1976-1978 editions of basal readers and supplementary textbooks from that found in the 1974-1976 editions examined by Gwyneth E. Britton and Margaret C. Lumpkin, an analysis of more than 3,700 stories was undertaken. The sex dominance of a story was determined by identifying the main character and by examining the accompanying illustrations. Each story was then classified as "male dominant,""female dominant," or "other." The resulting data showed that the 1976-1978 textbooks had a much smaller number of stories classified as "male dominant" than did the 1974-1976 editions. The newer editions also showed a marked increase in the number of stories classified as "other" and as "female dominant." (FL)
