The purpose of the present study was to reveal the effectiveness of the Nature of Science (NOS) embedded in Argument-Driven Inquiry (ADI) instructional method on pre-service science teachers' (PSTs) content knowledge and self-efficacy in evolution theory. The study was a mixed-method study in which the qualitative data collection and analysis was…

An understanding of biological variation is important for understanding ecological interactions, ecosystem function, and species' response to environmental change. Biological variation is essential to species survival because natural selection acts upon the phenotypic variation within a population: the more varied the population's genetic…

Evolutionary theory is a central tenet of biological science, and it is essential for all science teachers, early childhood through secondary, to have a clear understanding of not only the science behind evolution, but also the legal precedents for teaching evolution in the classroom. This study examines the effectiveness of a curriculum on…

Understanding genetic drift is crucial for a comprehensive understanding of biology, yet it is difficult to learn because it combines the conceptual challenges of both evolution and randomness. To help assess strategies for teaching genetic drift, we have developed and evaluated the Genetic Drift Inventory (GeDI), a concept inventory that measures…

Designed to address the major conceptual problems associated with evolution and variation and survival in populations, this module can be used with high school students or college nonscience majors including those in elementary education. It is one in a series developed by the project "Overcoming Critical Barriers to Learning in Nonmajors'…
