Abstract
Introductory college biology students were surveyed to investigate their attitudes toward evolution. Thurstone's Scale No. 30, Form A, Attitudes Toward Evolution was used to survey the sample. Results indicate that the majority of introductory biology students believe in the theory of evolution. Two demographic variables, sex and influence of the church, produced a significant correlation with the attitude scores. There were significant interactions between sex and influence of high school biology teacher and between sex and major. Self rating by the individual students and attitude scores also produced a significant correlation. Construct validity of the attitude scale was supported by the significant correlation between student self rating and scale scores. ANOVA produced a F value significant at the 0.01 probability level, and Spearman's correlation coefficient between the two measures was 0.73. Although the Thurstone Scale No. 30, Form A, is over 45 years old, the results of this study suggest that it is a reliable instrument for use today with modifications in item construction, scaling or adaptation to other scoring methods.
