The mineral identification lab is typically the entry level college student's initial hands-on introduction to minerals. Our research focused on identifying alternative mineralogy conceptions that students bring to an introductory geology course and investigating the origins and nature of these conceptions. We identified a number of alternative…

Spatial reasoning ability is key to an individual's understanding of geology and geosciences more broadly. One reason why is because spatial ability allows individuals to use multiple external representations (MERs) to understand information that they cannot normally interact with directly, such as the Earth. This article presents results from two…

Spatial reasoning is one of the most challenging skills to master in the science, technology, engineering, and mathematics (STEM) fields. This article reports the results of a teaching intervention that involved using wooden blocks to enhance the development of spatial reasoning in an undergraduate-level introductory geology course. Wooden blocks…

Scientific observation is central to classroom inquiry and children's investigations and explanations in science. Young children can struggle with observation, and research has shown that professional scientists who engage in complex observation tasks, observe detailed patterns when they have well-developed disciplinary knowledge. However, fewer…

The comprehension and calibration of 54 undergraduates were investigated as they read excerpts from an introductory geology textbook on weather and soil in print and digitally. All excerpts were approximately 1600 words in length and contained a graph, a diagram, and three photographs that complemented or extended the written text. Each student…

Most of the research on student understanding of evolution by natural selection has focused on undergraduate biology courses for science majors. However, the majority of undergraduates in the United States will not enroll in a biology course for majors. In this study, we identify the extent of natural selection understanding that students acquire…

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…

We present a quantitative study of responses to voluntary and anonymous surveys of undergraduate geology students enrolled at an English-medium, research university in South Africa. This research captured student interest in geology, their perceived level of understanding of key geological concepts, and the extent to which in-class and in-field…

The studies in this dissertation were conducted to better understand how to measure students' use of multiple representations in introductory science courses by expanding the possibilities of a variable representation assessment (VRA). The VRA is a computer-based assessment originally designed to measure general chemistry students' use of…

The study consisted of three articles. Article one aimed to determine if there were any significant difference in science graduate students' (SGSs') conceptions of the "consensus tenets" of the nature of science (NOS) with respect to demographic factors -- the SGSs' academic and research characteristics. The participants were SGSs from…

This paper analyses the conceptions of a group of students about geological time and its relation to physical landscape formation, focusing on the frequency and rate of a number of geological processes that have shaped our planet over time and that are involved in the formation of the current relief. Data were collected by means of a questionnaire…

In an introductory geology course on vertebrate fossils, a new object-based classroom exercise was designed to enhance students' appreciation for evidence of evolution as a "tinkering" process, specifically in modern organisms with which everyone is familiar. During the dissection of a popular college late-night snack (barbeque-style…

Undergraduate students have different attitudes toward the geosciences, but few studies have investigated these attitudes using Q methodology. Q methodology allows the researcher to identify more detailed reasons for students' attitudes toward geology than Likert methodology. Thus this study used Q methodology to investigate the attitudes that 15…

A sample of 43 Mississippi school counselors was surveyed regarding resources they use in career counseling, as well as resources they believe are effective in informing students about STEM careers, particularly the geosciences. Participants were asked a number of questions about their knowledge and perceptions about STEM majors and careers. The…

With the continuous development and innovation of information technology, virtual reality (VR) has become an important topic of education technology in recent years. VR is not only applied in many industries, but is also used by scholars for education applications as it enables students to have an immersive learning experience to enhance their…
