For the past 5 years I have been teaching my introductory geology class using a case-based method that promotes student engagement and inquiry. This article presents an explanation of how a case-based curriculum differs from a more traditional approach to the material. It also presents a statistical analysis of several years' worth of student…

An introductory geology class that satisfies a liberal arts distribution requirement was used to investigate the benefits of allowing discussion during assessments. For three term examinations, students completed short- to medium-length essay tests individually (individual examination) and then again as part of an assigned group of four to five…

At the University of Vermont, an interdisciplinary faculty team developed an introductory watershed science field course. This course honed field skills and catalyzed communication across water-related disciplines without requiring specific prerequisites. Five faculty (geology, engineering, geography, natural resources) taught the four-credit…

In order to guide the formulation of strategies for recruiting undergraduates into the geology program at Northern Arizona University, we surveyed 783 students in introductory geology classes and 23 geology majors in their junior and senior years. Our analysis shows that ~7% of students in the introductory classes are possible candidates for…

Laboratories serve as an integral part of geoscience education at most colleges and universities. While anecdotal evidence supports the beneficial impact of laboratories on science class learning, little quantitative research backs this statement. This study compared classroom data from students who completed a geoscience laboratory in conjunction…

Geoscience teaching has primarily been oriented toward the value of science to explain natural systems. However, many kinds of values guide people's responses to environmental problems, which originate when human expectations fail to match the behavior of natural systems. Examples from the literature show that practical environmental…

Earth systems increase in complexity, diversity, and interconnectedness with time, driven by tectonic/solar energy that keeps the systems far from equilibrium. The evolution of Earth systems is facilitated by three evolutionary mechanisms: "elaboration," "fractionation," and "self-organization," that share…

Student knowledge of the Nature of Science (NOS) is critical to their understanding of science. NOS encapsulates the tenets of how science is regarded and the heuristics by which science is judged to be valid and appropriate. The importance of NOS to science education has lead to curricular and policy development that mandate the construct be…

Although active learning methodologies have been implemented in geoscience classes successfully, no direct comparison between these different instructional techniques exists to date. For that reason, the purpose of this study was to compare the effectiveness in student learning of two active learning methods: peer instruction and lecture…

We have developed and implemented a summary field exercise for an introductory hydrogeology course without a laboratory section. This exercise builds on lectures and problem sets that use pre-existing field data. During one day in April, students measure hydraulic heads, stream and spring flow, and stream-bed seepage within the rural watershed of…

Many students view equations as a series of variables and operators into which numbers should be plugged rather than as representative of a physical process. To solve a problem they may simply look for an equation with the correct variables and assume it meets their needs, rather than selecting an equation that represents the appropriate physical…

Collaborative exams, with subsections in which students have an opportunity to work with each other, are not yet widely used in introductory geoscience courses. This type of exam structure, with other participatory teaching strategies, was employed in two different courses, and results were found to provide a sensitive and revealing tool for…

Electronic course materials, such a videos, PowerPoint presentations, and animations, have become essential educational tools in classroom-based geoscience courses to enhance students' introduction to basic geological concepts. However, during field trips, the ability to offer students these electronic conceptual supports is lacking where students…

Students test the hypothesis that the moon revolves east to west around the earth, determine by observation approximately how many degrees the moon revolves per night, and develop a scale model of the earth-sun-moon system in this laboratory exercise. Students are actively involved in the scientific process and are introduced to the importance of…

Presents an exercise in which cutouts or outlines of dinosaur footprints placed independently or in sets on the floor and laboratory benches are used to model dinosaur trackways. The nature, size, speed, and specific behavior of the trackmaker are determined from the trackways and from student-derived data as well as from diagrams and models based…
