A Formative Evaluation of Biological Science: Patterns and Processes, Final Report.
Mayer, William V.; And Others
Reported is a formative evaluation of the Biological Science Curriculum Study "Biological Science: Patterns and Processes", designed for academically unsuccessful students. "Criterion referenced" tests were developed, with items selected to indicate the extent of students' learning rather than to discriminate between students. An alternate form, pretest-posttest research design was used. Randomly selected students within classes of teachers who had participated in feedback and training activities were given alternate test forms for each of five content areas. Scores on these tests served as the dependent variables with scores on Verbal Reasoning and Numerical Ability subtests of the Differential Aptitude Test, and Davis Reading Test scores serving as independent variables. Data were also collected on school and community characteristics. Analysis of covariance and multiple regression analysis showed significant differences between classes (tentatively attributed to teacher performance), and significant correlations between reading comprehension and achievement. Recommendations are made for revision of the materials and for similar evaluative studies. Appended are tables of results and statistical analyses, and copies of tests used. (EB)
