Student Success Of Online Vs. In-Person Biology Courses At Virginia Community Colleges, Jennifer Claire Scott

Doctoral Dissertations and Projects

Community colleges have a significant role in preparing students for STEM-related careers through certificates, degrees, and transfers to four-year institutions. In addition, online education is a growing mode of higher education, particularly for community college students. However, community college and online students are both at a high risk of attrition and show a lower success rate for degree completion. The purpose of this study was to identify differences in attrition and success between students in online and in-person biology courses at Virginia community colleges. Also, this study addressed downstream effects of online education by examining course completion of second-semester biology …

Traffic Noise And Sexual Selection: Studies Of Anthropogenic Impact On Bird Songs And Undergraduate Student Reasoning Of Evolutionary Mechanisms, Sarah Spier

School of Natural Resources: Dissertations, Theses, and Student Research

Humans have transformed much of the natural landscape and are continuing to do so at an accelerated rate, compromising natural areas that serve as important habitat for many species. Roads impact much of the environment as they fragment habitat and introduce traffic noise into the acoustic environment, deferentially affecting wildlife in roadside habitat. I explored how traffic noise affects the detection of birds based on whether their vocalizations were masked by traffic noise. Masked species detection was not affected by an increase in traffic noise amplitude, while there was a negative effect of traffic noise amplitude on unmasked species detection, …

The Impact Of Mentoring On Life Science Undergraduate Mentors, Kari Nelson

Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research

Universities are increasingly encouraging their undergraduates to become mentors to others, yet relatively little research has been done to empirically understand the impact of this work on the mentors themselves. Therefore, the overall goals of this work were: (1) To evaluate the types of studies that have been conducted on the impacts of serving as an undergraduate mentor; (2) To examine the methodological rigor of recent studies and make recommendations for improvement; and (3) To asses if serving as an undergraduate mentor impacted the critical thinking of the mentors, using a valid and reliable instrument, the California Critical Thinking Skills …

How Do Undergraduate Stem Mentors Reflect Upon Their Mentoring Experiences In An Outreach Program Engaging K-8 Youth?, Kari L. Nelson, Jamie Sabel, Cory Forbes, Neal Grandgenett, William E. Tapprich, Christine E. Cutucache

Biology Faculty Publications

Background: Many university students are becoming involved in mentoring programs, yet few studies describe the impact of mentoring on the mentor. Additionally, many studies report that students graduating from college are not prepared to enter the workforce in terms of key career skills and/or content knowledge. Herein, we examine the impact of our program, NE STEM 4U (Nebraska Science, Technology, Engineering and Math for You), in which undergraduate (UG) mentors engage K-8 youth in after-school STEM experiments. The UGs reflected upon their experiences using post-mentoring evaluations, 12- and 24-week interviews, and exit surveys. Many of the questions asked of …

Ne Stem 4u: An Out-Of-School Time Academic Program To Improve Achievement Of Socioeconomically Disadvantaged Youth In Stem Areas, Christine E. Cutucache, Jamie L. Luhr, Kari L. Nelson, Neal Grandgenett, William E. Tapprich

Biology Faculty Publications

Background

The Nebraska Science, Technology, Engineering, and Mathematics 4U (NE STEM 4U) program was initiated at the University of Nebraska at Omaha (UNO) in 2013. NE STEM 4U is a student-run, faculty-led program facilitating problem-based learning (PBL) sessions in science, technology, engineering, and mathematics (STEM) for socioeconomically disadvantaged kindergarten through grade 8 (K-8) students. PBL sessions are provided throughout the academic year in a twice-weekly, after-school, informal education program. The instructional material provided after school builds upon the curricula of the school day. Importantly, this program is a partnership between faculty members and administrators in higher education at UNO with …

1. "Investigating The Impact Of Changes In Carbon Dioxide Concentration On Ecosystems", Sarah O'Leary-Driscoll, Crystal Randall

Ecosystem Disruption & Climate Change

Question: Does the concentration of carbon dioxide affect air temperature in a closed environment?

2a: "Illinois Carbon Dioxide Emissions Activity", Sarah O'Leary-Driscoll, Crystal Randall

Ecosystem Disruption & Climate Change

Your goal for this activity is to compare the different sources of carbon dioxide emissions, stemming from the consumption of fossil fuels, in Illinois. To do this you will be working with data spanning from 1980 to 2012.

Ecosystem Disruption & Climate Change

Information taken from: Dirzo, R. et al (2014). Defaunation in the Anthropocene. Science, 345(401).

Scientists estimate, conservatively, that there are 5 to 9 million different animal species on the planet. But that number is continually changing, and unfortunately, dropping, as we are likely losing 11,000- 58,000 species annually, and evidence suggests that on average, there has been a decline of about 28% in terms of numbers of individuals within a species over the last four decades. Both of these statistics are vitally important. The critical nature of the first is perhaps more obvious, as total loss of a species is …

The Greenhouse Effect: Does The Concentration Of Carbon Dioxide Affect The Air Temperature In A Closed Environment?, Climate Science Investigations - Nasa

Genetic Drift Simulation, Imsa Biology Team

Evolution

Genetic drift can be defined as a random fluctuation in gene frequency. More specifically, it tells us that different alleles may increase or decrease in a population in proportion to one another over time, just by chance, rather than due to any fitness advantage.

Alignment Information, Sarah O'Leary-Driscoll

Sequence Alignments

Pairwise DNA alignment is frequently used to identify similar regions that will show how two sequences have functional or structural similarities. It can also be used to show how exons and introns change between different sequences and whether they have an effect on the final structure of the RNA after the DNA is processed within a cell.
