For many students, the first--and sometimes only--chance to look through a microscope is in high school biology class, where they observe plant and animal cells up close. Even in college, few students use a microscope for a subject other than biology. Thus, it can be a surprise to learn that microscopes are a primary tool used to understand the…

Although science educators at all levels have focused on teaching students scientific literacy for nearly five decades, studies indicate that the average student remains far from scientifically literate. To address this issue at the local level, faculty at Trinity University, in San Antonio, Texas, significantly revised the curriculum of an…

The incorporation of reformed, inquiry-based pedagogies in introductory courses has been shown to improve content knowledge, student retention, interest and attitudes towards science. However, there is evidence that suggests these techniques are not being widely used by the geoscience community. This research focuses on the incorporation of…

As an aid for teaching phase equilibria to undergraduate students of igneous and metamorphic petrology, we have designed a laboratory exercise that allows them to create a phase diagram from data produced by differential scanning calorimetry. By preparing and analyzing samples of naphthalene and phenanthrene, students acquire hands-on insight into…

Applies chemistry to earth science, uses rocks in chemistry laboratories, and teaches about transition metal chemistry, oxidation states, and oxidation-reduction reactions from firsthand experiences. (YDS)

The study reported here concludes that the laboratory does help students in their geology lecture course work even though the content emphases are different. (MDR)

Describes a topographic map exercise designed for lab session of two to three hours in an introductory geology course. Students are taught the basic principles of topographic map construction and are then required to make a map of a section of campus. Author claims the approach has improved student test performance and resulted in a deeper…

At many colleges and universities undergraduates pursuing nonscience majors complete introductory science courses which are structured to provide a broad overview of the field. Commonly such courses include large lecture sections which meet twice a week, and small lab sections that are held once a week. A survey was developed to evaluate the…

Describes an approach to introductory geology that requires students to go into the field to make observations, collect and analyze data, synthesize those data, and hypothesize about inferred geologic relationships. The product of these laboratories is a paper that requires students to test their hypothesis using specific examples from the data.…

Explains how students can learn basic petrographic techniques by using a thin-section collection prepared from the rock units in a geological area under study. Each student defines a particular problem to investigate and is responsible for collecting samples in the field, making additional thin sections, and preparing formal written and oral…
