There is an emphasis on survival-based selection in biology education that can allow students to neglect other important evolutionary components, such as sexual selection, reproduction, and inheritance. Student understanding of the role of reproduction in evolution is as important as student understanding of the role of survival. Limiting…

Threshold concepts are fundamental to a discipline and, once understood, transform students' understanding and perception of the subject. Despite the value of threshold concepts as a learning "portal" for heuristic purposes, there is limited empirical evidence of threshold crossing or achieving mastery. As a threshold concept, biological…

The theory of evolution is the backbone of the biological sciences. Arguably, this is the reason why evolution education is an extensively investigated issue in several countries around the world. Little is known, however, about the views of university students in Colombia. Here, we report on 7 years of data generated by a three-question anonymous…

We describe a hands-on, collaborative activity designed to illustrate general properties of evolution, provide practice for quantitative skills, promote creativity and collaboration, and enable student self-assessment of learning. During the activity, teams construct bridges using common office supplies. The best-performing bridge becomes the…

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…

Evolutionary theory is central to the biological sciences, and to critical aspects of everyday life, and yet a significant proportion of Americans reject evolution. Our study sets out to examine the role of a second year college general education course in affecting students' acceptance of evolution. We report three years of data using the Measure…

Darwin's theory of evolution is explicitly competitive, yet co-operation between individuals is a common phenomenon. The Prisoner's Dilemma model is central to the teaching of the evolution of co-operation. The best-known explorations of the Prisoner's Dilemma are the tournaments run by Robert Axelrod in the 1980s. Aimed at students of biological…

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…

Interpreting cladograms is a key skill for biological literacy. In this lesson, students interpret cladograms based on familial relationships and language relationships to build their understanding of tree thinking and to construct a definition of "common ancestor." These skills can then be applied to a true biological cladogram.

We assessed the performance of students with a self-reported conflict between their religious belief and the theory of evolution in two sections of a large introductory biology course (N = 373 students). Student performance was measured through pretest and posttest evolution essays and multiple- choice (MC) questions (evolution-related and…

Certain scientific conclusions are controversial, in that they are rejected by a substantial proportion of nonscientists despite an overwhelming scientific consensus. Science educators are motivated to help students understand the evidence behind the scientific consensus on these matters and to move students' views into alignment with those held…

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…

The understanding of core concepts and processes of science in solving problems is important to successful learning in biology. We have designed and developed a Web-based, self-directed tutorial program, "SOLVEIT," that provides various scaffolds (e.g., prompts, expert models, visual guidance) to help college students enhance their…

Recent research suggests that a major obstacle to evolution understanding is an essentialist view of the biological world. The present study investigated the effects of formal biology instruction on such misconceptions. Participants (N = 291) completed an assessment of their understanding of six aspects of evolution (variation, inheritance,…

College students often come to the study of evolutionary biology with many misconceptions of how the processes of natural selection and speciation occur. How to relinquish these misconceptions with learners is a question that many educators face in introductory biology courses. Constructivism as a theoretical framework has become an accepted and…
