The adoption of active learning instructional practices in college science, technology, engineering, and mathematics (STEM) courses has been shown to result in improvements in student learning, contribute to increased retention rates, and reduce the achievement gap among different student populations. Descriptions of active learning strategies have been reported in other disciplines; however, the research literature that documents the success of these strategies may be unfamiliar to many geoscience instructors. This literature review seeks to serve as a bridge that connects the reflective practitioner, the research literature on instructional strategies, and the network of community resources available to the geoscience educator. We review the characteristics of 11 active learning strategies and weigh the evidence that these strategies improve student learning. Furthermore, we analyze the utility of these strategies in the context of their use in geoscience classrooms. We seek to provide geoscience instructors with a decision-making guide and evidence-based recommendations that they can use to select and implement active learning strategies that have the potential to enhance undergraduate learning experiences in geoscience courses.

The introductory physical geology laboratory courses taught at North Carolina State University aims to promote scientific thinking and learning through the use of scientific inquiry–based activities. A rubric describing five possible levels of inquiry was applied to characterize the laboratory activities in the course. Two rock and mineral laboratory classes and a geologic time laboratory class were found to contain a greater proportion of low-level inquiry activities than the other laboratory classes. Student exercises within these classes were modified by increasing the degree of student independence, exploration, and prediction required for several activities. Such modifications included students categorizing rock samples before instruction on rock types and predicting the placement of fossils along a geologic time line. Learning gains were measured and compared between students in the traditional lower-inquiry (control) and the revised higher-inquiry laboratory classes (treatment). In all thr...
