On The Straight And Narrow: How Cultural Beliefs About Sex/Gender Manifest In College Biology Learning Environments., Katherine Ray Kng

Electronic Theses and Dissertations

This dissertation focused on the ways that social beliefs about sex/gender and sexuality manifest in biology classrooms. Especially for health science students, classes include topics like sex, sexuality, sexual behaviors, or sex determination that forms the foundation of their understanding of human forms and behaviors. If the information they receive does not include the LGBTQIA+ community, their education will fail to adequately prepare them for the reality of healthcare practice where they will be expected to treat all patients with dignity and respect. There are three chapters in this dissertation. In chapter one, I asked what beliefs about and conceptions …

Undergraduate Students Use Moral Reasoning And Belief In Genetic Determinism In Response To A Crispr/Cas9 Socioscientific Issue., Katie M. Seiter

Electronic Theses and Dissertations

This dissertation explores how students reason about genetic engineering socioscientific issues (SSIs) related to a recently developed, powerful genome editing technology called CRISPR/Cas9. It is divided into three chapters. Chapter One describes an exploratory study that characterized students’ moral reasoning using a sociocultural theoretical framework. I used content analysis and logistic regression to investigate how academic and social factors influenced moral reasoning. Students generally opposed the use of CRISPR/Cas9 technology for non-medical enhancements, and the moral considerations used were influenced by genetics knowledge level and demographic variables such as gender and socio-economic status. Further investigation of moral perspectives for students …

Comparison Of Retention Rates Between Traditional On-Ground And Online Biology Laboratory Courses In The Community College Setting, Megan Davis Winborne

Dissertations

Community colleges provide vital educational resources to students across the nation. Online learning has become an integral part of the course offerings for community colleges. With regards to online learning, there is a lack of empirical evidence and research focused on community college offered biology laboratories, particularly concerning retention rates of these students. Means, Toyama, Murphy, and Bakia. (2013) found that even though there are copious amounts of studies dedicated to evaluation of evidence-based practices in online learning formats, many of them neglected to review retention rates associated with online educational courses.

The purpose of this study was to determine …

Short- And Long-Term Impacts Of A Deliberative Pedagogy In Introductory Biology And Chemistry Courses, Liz Rain-Griffith

Dissertations and Theses

There have been multiple national calls for curricular reform in college-level science, technology, engineering, and mathematics (STEM), including a need to instill democratic skills in students. Democratic skill building can be embedded in STEM classrooms through intentional "deliberative pedagogies" which include skills in: communication, collaboration, and application. We developed and implemented a deliberative pedagogy, Deliberative Democracy (DD), across introductory majors and non-majors biology courses and a majors chemistry course. In two separate studies, I took a longitudinal, qualitative research approach to understand introductory biology and chemistry students' experiences and perceptions of DD. For the first study, I tracked a cohort …

From Theory To Practice: Interdisciplinary Science In Undergraduate Education, Brie Tripp

Dissertations and Theses

Science has undergone a major transformation in the 20th and 21st centuries with new fields emerging at the intersection of disciplines, such as bioethics, bioinformatics, and chemical ecology. Yet, opportunities to engage with interdisciplinary science, and the skills needed to work in these fields, are largely absent from undergraduate biology classrooms. As a consequence, students are potentially deprived of opportunities to think interdisciplinarily and engage with real-world issues that often necessitate interdisciplinary efforts. To be informed citizens in society and forward-thinking scientists in the workforce, undergraduate students will undoubtedly benefit from exposure to these interdisciplinary science experiences.

Given these considerations, …

An Investigation Of The Impacts Of Traditional, Virtual, And Hybrid Biological Laboratories On College Students’ Achievement And Motivation To Learn Biology, Shavonda Jackson

Dissertations

Virtual courses function in a different manner than traditional courses, therefore they require teaching methods and assessment techniques geared specifically to maximize this learning experience. Internet-based learning and distance-education are no longer new concepts in the science field. Because of this, many collegiate biology programs have created courses that can be taken virtual or hybrid. A number of experimental studies have had great influence in terms of the effects and impacts of educational technology in relation to virtual laboratories.

However, not many studies emphasize the impact of hybrid laboratories on student achievement or assess students’ motivation to learn in a …

Antimicrobial Properties Of An Unknown Microorganism Isolated From The Local Environment, Danielle Duryea

Undergraduate Honors Thesis Projects

Bacterial species that cause disease can usually be combatted with antibiotics; but as the years pass, more and more bacterial pathogens are becoming resistant to these treatments. In fact, the Center for Disease Control has identified eighteen classes of bacteria ranging from urgent to concerning threats due antibiotic resistance (2019), warning the advance of an antibiotic resistance crisis in which untreatable bacterial infections will become a leading cause of death (Bennadi, 2014). The Small World Initiative is a program created in 2012 at Yale University to address the antibiotic crisis through a crowdsourcing effort where undergraduate students are encouraged to …

A Reexamination Of The Freshwater Mussel Community Of The Little Miami River, Emily Davis

Undergraduate Honors Thesis Projects

Understanding the changes in biodiversity and local freshwater mussel populations is critical to mitigate the risks to these populations. Freshwater ecosystems continue to degrade rapidly. The freshwater mussel community of the Little Miami River is degraded and has been in decline for many years. The biodiversity contained within freshwater ecosystems is lost at unprecedented rates influenced by human activity. Freshwater mussels play a key role in understanding the effects of human activity on freshwater ecosystems as well as maintaining the health of freshwater habitats. However, they are also sensitive to changes and disturbances, in their ecosystems. This study involved monitoring …

Reconsidering Undergraduate Anatomy And Physiology Curriculum, Eric Michael Walsh

Theses and Dissertations

In the past 50 years several convergent factors have spurred unprecedented change in anatomy and physiology (A&P) instruction. An explosion of biomedical knowledge, an increased demand for students well-versed in A&P, and decreased resources for the course has provoked a vast array of research. However, most studies employ one of three strategies to enact change: testing the effectiveness of new pedagogies, exploring the utility of new technologies, or documenting learning in new contexts. By comparison, a much smaller body of research focuses on changing the A&P curriculum to improve student learning. To address this gap, the musculoskeletal curriculum for an …

Students' Performance, Satisfaction And Retention In A Hybrid And Traditional Face-To-Face Science Course, Principles Of Biology I, In A Community College, Abdallah Mohammad Matari

Seton Hall University Dissertations and Theses (ETDs)

Hybrid teaching, comprised of both in-class and online teaching, is rapidly becoming a favorite mode of teaching and learning. Online and hybrid courses on have become more and more appealing to both higher education institutions and the students they serve. In particular, hybrid teaching has an increase appeal to community colleges as they serve a diverse student population with varied academic levels, cultural background, and personal responsibilities. Hybrid courses promotes flexibility in course scheduling options for students and enables institutions to accept more students without worrying about physical classroom space concerns. This study explored and compared students’ learning outcomes, satisfaction, …

Analysis Of The Impact Of Professional Learning Teams On Teaching Practices And Student Achievement In Biology Using Dufour’S Model, Rowena K. Dawkins

Doctor of Education Dissertations

This mixed-methods study addresses the perceived impact of working in Professional Learning Teams (PLTs) on teaching practices and student achievement in biology. The study replicates Roberts’s (2010) study. Success in biology is important to the nation because it aligns with national efforts to prepare students to compete in global markets. Educators use PLTs to support development of educators and address student educational needs. PLTs share basic functions. Basic functions were defined using DuFour’s (2004) three big ideas of PLCs: ensuring students learn at high levels, promoting a collaborative culture, and focusing on academic results. Biology teachers completed an anonymous online …
