Exploring Undergraduate Research Experiences And Perceptions Of Responsible And Ethical Conduct Of Research (Recr) Education In The Biological Sciences And (Bio)Chemistry Disciplines, Bernice Justina Caad Aug 2023

Exploring Undergraduate Research Experiences And Perceptions Of Responsible And Ethical Conduct Of Research (Recr) Education In The Biological Sciences And (Bio)Chemistry Disciplines, Bernice Justina Caad

Open Access Theses & Dissertations

Increasing calls to reform undergraduate (UG) education within science, technology, engineering, and mathematics (STEM) disciplines have emphasized the importance of early exposure to responsible and ethical conduct of research (RECR) education. Historically, RECR has primarily been presented at the post-baccalaureate level, leaving many students without a foundational understanding of what responsible research ethics entails during the course of their undergraduate experience. Over the last decade, course-based undergraduate research experiences (CUREs) have emerged as a promising platform to establish expectations of responsible and ethical conduct through greater accessibility and inclusivity, starting at the freshman level. Interestingly, few studies have examined how …

Students Interest And Thoughts On Stem, Chrisitine Girtain Apr 2022

Students Interest And Thoughts On Stem, Chrisitine Girtain

STEM Month

I am Juan Sebastian Bohorquez Mora, I am a sophomore student at Toms River High School North. I am interested in biofuels because I believe they are a good option to replace fossil fuels. I am also interested in duckweed because biofuels are made out of crops, and people need to eat those crops. That’s when duckweed comes in and it can be used as a feedstock for ethanol production which is a biofuel. Bioethanol is a type of biofuel and it is derived from the corn’s starch. Instead of making ethanol from the corn’s starch, we can use duckweed …

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 …


The Potential Of Socio-Biologically Relevant Mobile Applications To Attract Girls To Stem, Vanaja Nethi, Santanu De May 2019

The Potential Of Socio-Biologically Relevant Mobile Applications To Attract Girls To Stem, Vanaja Nethi, Santanu De

FDLA Journal

Stimulating girls’ interest in science, technology, engineering and mathematics (STEM) when they are in school, and sustaining that interest, is critical in motivating girls to choose STEM-related disciplines in higher education and enter STEM careers. Research indicates that girls show an interest in STEM until about 11-12 years of age, but this starts to wane by the time they are 15-16 years. Thus, there is a clear need to focus on sustaining the interest of girls in STEM at middle or high school levels. Research has shown that one of the main drivers that impact girls’ interest in STEM is …


Bringing Science To Life In The Fifth-Grade Classroom Through Hands-On Learning, Kelly Gately May 2019

Bringing Science To Life In The Fifth-Grade Classroom Through Hands-On Learning, Kelly Gately

Honors Program Theses and Projects

Science helps provide insight into the unknown and provides an outlet for exploration of living things. Children are innately curious about how thing work, and they are eager to ask questions. Science is the perfect outlook for students to fully engage in their inquisitiveness, but yet, many classrooms are skipping over science lessons or choosing to heavily focus on other subjects, such as reading and writing. Science is often taught as an elective, integrated with other subjects or it is only focused on for a short period of time. Unfortunately, when this subject does receive attention, lessons are heavily text-book …

Biology Faculty Publications

Afterschool interventions in STEM are linked to learning gains during the school day. These opportunities engage and excite students about STEM concepts since they observe a more hands-on, project-oriented approach. Often these opportunities for afterschool interventions are infrequent in nature and leave gaps for students in their maturation and understanding. Herein we describe the first report of an afterschool intervention, named NE STEM 4U, targeting socioeconomically disadvantaged middle school youth via a twice weekly, year-long intervention, studied across two years. We assessed the impact of this program on i.) short-term, individual student gains in STEM content knowledge and ii.) delivery …

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 …
