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…

Misconceptions about adaptation by natural selection are widespread among adults and likely stem, in part, from cognitive biases and intuitive theories observable in early childhood. Current educational guidelines that recommend delaying comprehensive instruction on the topic of adaptation until adolescence, therefore, raise concerns because…

The idea that characteristics acquired by an organism during its lifetime can be inherited by offspring and result in evolution is a substantial impediment to student understanding of evolution. In the current study, we performed a preliminary examination of how acquiring physical changes in a question prompt may differentially cue intuitive and…

In this study, we explore how two different prompt types within an online computer-based inquiry learning environment enhance 392 7th grade students' explanations of evolution with three teachers. In the "elaborating" prompt condition, students are prompted to write explanations that support the accepted theory of evolution. In the…

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…

Biology instructors from middle school to university level recognize that natural selection is an essential topic in the curriculum. Numerous studies have shown the prevalence of many alternative conceptions about evolution that persist despite instruction in student populations all over the world. Having valid, reliable and easily used…

This study examines how a first-year biology teacher facilitates a series of whole-class discussions about evolution during the implementation of a problem-based unit. A communicative theoretical perspective is adopted wherein evolution discussions are viewed as social events that the teacher can frame intellectually (i.e., present or organize as…

Some ability to comprehend deep time is a prerequisite for understanding macroevolution. This study examines students' knowledge of deep time in the context of seven major historical and evolutionary events (e.g., the age of the Earth, the emergence of life, the appearance of a pre-modern human, "Homo habilis"). The subjects were 126…

This qualitative study analyzed grade 12 biology students' answers to written extended-response questions that describe hypothetical scenarios of animals' evolution. We investigated whether these type of questions are suitable for students (n = 24) to express a meaningful understanding of evolutionary theory. Meaningful understanding is comprised…

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…

This case study explored sociocultural forces that influenced three 10th grade public high school biology teachers' instructional goals, instructional acts, and identity narratives related to the teaching of evolution. Primary data included field observations of classroom instruction and teacher interviews. Secondary data included informal…

Describes the commitments and research that went into the design of a 9-week high school course in evolutionary biology designed to bring students to an understanding of the practice of evolutionary biology by engaging them in developing, elaborating, and using one of the discipline's most important explanatory models. (Contains 39 references.)…

Students often hold strong attitudes regarding topics they encounter during their studies, and many instructors feel that these attitudes can have strong effects on students' performance. We characterized students' attitudes toward evolution and investigated the influence of students' attitudes (pre-course and post-course) regarding evolution on…

Explores the effects of students' inquiry during a technology-supported unit of evolution and natural selection on their beliefs about the nature of science. Shows that the inconsistency of individual responses undermines the assumption that students have stable, coherent epistemological frameworks. Indicates differences between student talk…

Explores how biology majors accommodate the theory of biological evolution with religious beliefs. Responses clustered under for evolution, against evolution, compromise, and neutral. Suggests that teaching about the nature of scientific facts and theories can enhance understanding of evolutionary theory if students can discuss their values and…
