Development and Preliminary Evaluation of the Measure of Understanding of Macroevolution: Introducing the MUM

摘要: The challenges in teaching and learning of biological evolution continue to be documented (NAS, 2008). Developers science standards their work increase emphasis on evolution. Although gains have been made, many K–12 curricula focus microevolution (i.e., natural selection, genetic drift), a more limited effort is place provide exposure macroevolution speciation). Many the public's fundamental questions concerning actually stem from macroevolutionary changes. This research involved development psychometric evaluation Measure Understanding Macroevolution (MUM), an assessment college undergraduate understanding scientific portrayal macroevolution. MUM comprises 27 multiple-choice items 1 free-response item. authors achieved content validity based feedback professional biologists educators. was field tested with 3 unique cohorts students (N = 795). validity...
