Abstract

This study examines the relationship between biology teachers' evolution teaching practices and their regard and use of Indiana state evolution standards. A survey developed by the authors contained five subscales: use of standards; attitude toward standards; attitude toward evolution standards; evolution teaching practices; and demographic information. This survey was administered to 229 Indiana biology teachers. Data were analyzed using the Rasch model to convert Likert rating scale data into ratio data used for parametric analyses. Correlation analysis revealed significant relationships between use of standards and attitude toward standards, attitude toward standards and evolution teaching practices, and attitude toward evolution standards and days teaching evolution. These findings suggest practical relationships between standards use, teachers' regard of standards, and evolution teaching practices. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 44: 236–257, 2007
