We evaluated influences on the climate change risk perceptions of undergraduate students in an introductory Earth Science course. For this sample, domain-specific content knowledge about climate change was a significant predictor of students' risk perception of climate change while cultural worldviews (individualism, hierarchy) and political…

Nationwide pre- and posttesting of introductory courses with the Geoscience Concept Inventory (GCI) shows little gain for many of its questions. Analysis of more than 3,500 tests shows that 22 of the 73 GCI questions had gains of <0.03, and nearly half of these focused on basic physics and chemistry. We also discovered through an assessment of…

While interdisciplinary collaboration is desired among researchers, traditional science instruction generally results in science disciplines being taught as separate entities. This study focuses on student understanding of concepts at the intersection of two isolated disciplines--geoscience and bioscience--across two purposeful samples of…

Natural selection is a fundamental scientific process, yet students and educators alike demonstrate misconceptions of the process. Though images are used often in science to facilitate learning, it is less common to assess learners' understanding through their own drawings. This study utilizes a multiple-choice assessment of evolutionary processes…
