We validate the Measure of Acceptance of the Theory of Evolution (MATE) on undergraduate students using the Rasch model and utilize the MATE to explore qualitatively how students express their acceptance of evolution. At least 24 studies have used the MATE, most with the assumption that it is unidimensional. However, we found that the MATE is best…

We present a multiple-choice test, the Montana State University Formal Reasoning Test (FORT), to assess college students' scientific reasoning ability. The test defines scientific reasoning to be equivalent to formal operational reasoning. It contains 20 questions divided evenly among five types of problems: control of variables, hypothesis…

With applications of Tree of Life data becoming ever more prevalent in everyday contexts, tree thinking has emerged as a vital component of scientific literacy. This article reports a study testing the hypothesis that instruction in natural selection, which is the primary focus of US evolution education at the high school and introductory college…

Research in contemporary biology has become increasingly complex and organized around understanding biological processes in the context of systems. To better reflect the ways of thinking required for learning about systems, we developed and implemented a pedagogical approach using box-and-arrow models (similar to concept maps) as a foundational…

Although a well-corroborated scientific theory, the theory of evolution has continued to cause dilemmas for some individuals who have not easily been able to accommodate the concepts of this theory within their cognitive culture. The reason lies in the overlap of some ideas that the theory advocates with other social, epistemological, and…

Thurstone's Scale No. 30, Form A was used to survey attitudes of introductory college biology students (N=120) toward evolution. Results indicate the majority of these students believe in the theory of evolution. In addition, two demographic variables, sex and church influence, produced a significant correlation with the attitude scores.…

Ability of five cognitive characteristics to predict students' (N=96) achievement of evolution and natural selection concepts was measured. Results, among others, indicate that disembedding ability, prior knowledge, and evolutionary belief were significantly related to achievement while developmental level and mental capacity were not.

Discussed are the results of a test administered to nonmajor biology students on the topic of natural selection. The description of student conceptions, effects of instruction, and the effects of a belief in evolution are included. (KR)
