A five-point school subjects attitude scale, based on the semantic differential technique, was developed after two rounds of factor analysis; it contained 24 bipolar adjectives, each representing one of three factors: evaluation, usefulness, and difficulty. The scale was administered to Alberta (Canada) students in grades 5 and 8, who were identified by their teachers as having the most positive or least positive attitude toward social science. Students rated four subjects: (1) social science; (2) science; (3) subject most liked, useful, or difficult; (4) subject least liked, useful, or difficult. The scale was highly reliable on the evaluation and usefulness factors, and adequately reliable on the difficulty factor. It distinguished clearly between students identified as having positive or negative attitudes toward social studies. Males had a more positive attitude toward science but did not differ significantly from females on social studies ratings. Attitudes of subculture students became more negative from grade 5 to grade 8. A second study improved test-retest reliability of the usefulness and difficulty factors, established scale reliability for grades 5 to 11, and recommended development of norms.
