A study compared the sex roles depicted in the 1963 Scott Foresman basal series with those of the 1978 series to determine if changes had occurred. A total of 172 stories from 16 readers were analyzed using the Checklist for Evaluating Sexism in Reading. Each story was examined for the number of times males and females were portrayed as main characters and the number of times each sex was illustrated. The types of traits found in male and female children and adults were also recorded. The results indicated that the publisher had made positive attempts to remove sexism from the basal series. There was a slight improvement in male-female ratios in illustrations, main characters, and active roles; and females were more numerous in the 1978 edition. Many of these females were depicted as active, resourceful, brave, and adventurous. (FL)
