Assessing the efficacy of the Measure of Understanding of Macroevolution as a valid tool for undergraduate non-science majors

摘要: Efficacy of the Measure Understanding Macroevolution (MUM) as a measurement tool has been point contention among scholars needing valid measure for knowledge macroevolution. We explored structure and construct validity MUM using Rasch methodologies in context general education biology course designed with an emphasis on macroevolution content. The model was utilized to quantify item- test-level characteristics, including dimensionality, reliability, fit model. Contrary previous work, we found that provides valid, reliable, unidimensional scale measuring introductory non-science majors, its psychometric behavior does not exhibit large changes across time. While all items provide productive information, several depart substantially from ideal behavior, warranting collective effort improve these items. Suggestions improving characteri...
