The purpose of this study was to assess and describe the status of program evaluation within the National Science Foundation's (NSF) Research Experiences for Undergraduates (REU) sites. The National Science Foundation's REU program supports thousands of undergraduates annually in hands-on, immersive research experiences under the mentorship of…

Undergraduate general chemistry courses are often perceived in a negative light by students. Student attitudes towards chemistry play a significant role in their success in chemistry and retention in STEM altogether. Research has shown in K-12 classrooms that care-based instruction strategies can help to improve student attitudes towards…

This three-paper dissertation addresses the experience and the implementation of evidence-based learning practices in science, technology, engineering, and mathematics (STEM)/biology education. Study 1 explored instructional strategies and student perceptions and preferences for various teaching practices in graduate and undergraduate classrooms…

While zinc (Zn[superscript 2+]) is a vital ion for cell function and human health, we are still learning about how Zn[superscript 2+] concentration and localization is regulated and the role that Zn[superscript 2+] fluctuations may play in regulating cell signaling and cell fate. Here, we use fluorescent tools to study the interaction between…

A growing body of literature focusing on undergraduate biology education calls for students to engage in the ways of thinking, feeling, and doing that reflect those in which biologists engage. Such reform efforts suggest that learning is best fostered when students engage in practices, concepts, and scientific reasoning as they endeavor to explain…

Through this qualitative phenomenological I studied the lived experiences of online science instructors who teach online introductory science. The problem addressed in this study was the high failure and attrition rates in online introductory science courses among undergraduate students. The purpose of this study was to explore the lived…

Responsive teaching is an approach to instruction that foregrounds listening for, attending to and engaging with student disciplinary thinking and ideas in the classroom. This style of teaching differs from how many traditional STEM classes are taught, especially at the college level. Entry-level college science courses that are taught by graduate…

This study tested the hypothesis that exploratory learning, with and without analogous problems, would improve students' ability to make connections between conceptually-related topics. In this randomized experiment, undergraduates in introductory physics (N = 171) studied a new topic under three different instructional conditions. Order and type…

This qualitative study examines the semiotic meanings communicated through multiple representations in the teaching of an advanced undergraduate course in biology. Scientific discourse is intrinsically multimodal in nature; in other words, science is discussed and researched using multiple modes that convey meaning (Lemke, 1998). Therefore, to…

While it is well established that pedagogies purposefully linking subject matter to students' cultural contexts and prior knowledge can help students learn subject matter, little is known about practices for so doing in undergraduate biology courses enrolling substantial numbers of racially, culturally, and otherwise diverse students. This study…

Spatial intelligence is an essential skill commonly used within various fields of science. Students with low spatial abilities frequently struggle to identify, retrieve, and apply key complex abstract information presented as multiple representations to actual three-dimensional natural materials and phenomena. Spatial ability may be considered a…

The purpose of this study was to understand the factors that support the adoption of active learning teaching strategies in undergraduate courses by faculty members, specifically in the STEM disciplines related to geoscience. The focus of the study centered on the context of the department which was identified as a gap in evaluation and…

The first courses freshman university students typically enroll in are the introductory science and math, courses that bridge from and build upon their prior educational experiences. These introductory courses often have large enrollment lectures coupled with supplemental sessions to teach using traditional educational practices, which may operate…

The enacted curriculum and classroom artifacts of a full unit of instruction from three subject areas (biology, chemistry, and physics) at two levels of instruction (regular and advanced) were analyzed for the presence and degree of mathematics and critical thinking. These characteristics were selected from a review of the literature on college…

Prominent Feature Analysis (PFA) is a reliable and valid writing assessment tool, derived from the writing it is used to assess. PFA, used to assess on-demand expository essays in Grades 3-12, uncovers positive and negative characteristics of a sample. To extend PFA to a new academic level and genre, I assessed scientific writing of 208…
