Investigating Students' Interpretations Of Ecological Food Webs, Christopher Neil Grissett

USF Tampa Graduate Theses and Dissertations

To better prepare undergraduate students for current and future biological challenges, scientists, educators and researchers in the Vision and Change report recommended five core conceptual areas essential for the improvement of biological literacy, one of which is biological systems. Systems are an identified core concept that may help promote biological literacy. One example of a system that students have difficulty understanding is an ecological food web, which consists of parts or components interacting with one another to perform a given phenomenon. The intricacies of this system tend to confuse students and can produce naïve conceptions that could hinder future learning …

Evaluating The Impact Of Intersecting Research And Outreach Marine Science Programs On Elementary And Undergraduate Students, Randi J. Sims

All Theses

Climate change is one of the most destructive forces our ocean is currently experiencing. Despite this, many students are not taught the basics of climate change science and ocean literacy in public school systems. My work seeks to combat these deficits through educational experiences in marine science for undergraduate and local elementary students through three studies incorporating marine-science based research and outreach. (1) Through undergraduate marine science research and outreach, students enrolled for long durations or with positive mentorship increased their conceptual understanding of marine science concepts, altered their attitudes towards climate change and science, and were more likely to …

Mixed Method Analysis Of Undergraduate Student Interpretation Of Different Phylogenetic Trees, Faith Frings

USF Tampa Graduate Theses and Dissertations

Phylogenetic trees are common tools used to visualize evolutionary concepts such as historical patterns of ancestry, divergence of species, and descent of species. However, students have misconceptions when reading these abstract diagrams. The purpose of this study was to compare student performance and evolutionary thinking when using two styles of phylogenetic trees: cladograms and phylograms. The study also assessed the validity of a hierarchal theoretical framework evaluating student phylogenetic tree interpretation. Introductory biology students from two research universities were assigned to two groups, one solely given assessments with phylograms, and one solely given assessments with cladograms. One-on-one student interviews were …

Ours Lived Lived: Faculty Responses To Stem Students' Lived Experiences, Stan Nguyen

University Honors Theses

Science, technology, engineering and mathematics (STEM) fields have historically had low undergraduate retention rates. To aid in counteracting this, classroom exercises, or 'belonging interventions' can play a vital role in keeping new STEM students motivated through the "cultural shock" period of the college transition. However, much is still unknown about STEM instructors' perceptions on belonging interventions in STEM classrooms. Would understanding students' lives and experiences in the past and present help them make better informed decisions in their teaching practices?

To answer this question, we drew upon results from a belonging intervention conducted by the Biology Education Research (BER) group …

Generating And Sustaining Meaningful Professional Development Opportunities For Graduate Teaching Assistants Facilitating Course-Based Undergraduate Research Experiences In The Biological Sciences, Amie M. Kern

Open Access Theses & Dissertations

Current national efforts to reform postsecondary laboratory education have emphasized the incorporation of authentic research opportunities into science, technology, engineering, and mathematics (STEM) curricula. Within the last decade, course-based undergraduate research experiences (CUREs) have emerged as a viable mechanism to achieve this goal. Evidence within the biology education literature suggests that student engagement in CUREs has the potential to positively impact their development of scientific inquiry and process skills, content knowledge, and affect in the domain. While the majority of studies have focused on student outcomes, few studies have examined instructor outcomes in CURE learning environments. This is especially true …

Analysis Of Test Anxiety In Human Anatomy And Physiology I Students At The University Of Mississippi, Anne Piazza

Honors Theses

Student anxiety, specifically test anxiety, is common hindrance to student performance in various courses including Human Anatomy and Physiology at the University of Mississippi. Through a sequence of three surveys we collected demographic information, anxiety data related to the course, and test anxiety in general We researched factors that could potentially influence student anxiety such as at what point in the semester the student is evaluated, when students feel the most stressed, outcomes on previous evaluations, and perceived outcomes of the course. We also examined what effect the anxiety has on the student such as lowered performance, lowered test scores, …

Exploring The Relationship Between Art And Environmental Education, Mackenzie Haynes

Honors Projects

To explore the relationship between art and environmental education, I created a lesson plan and then put into practice at Crim Elementary School in a 4th grade art class. The art project had to do with the environment, endangered animals and recyclable materials. I titled the project "Habitat Heroes" and students had to imagine that they were the only people left on Earth along with a few animals and lots of trash. They were tasked with selecting an endangered animal in Ohio from one of five different groups (mammals, birds, reptiles/amphibians, birds and fish) to create a habitat for. The …

Effects Of Temperature And Plant And Animal Diets On Metabolic Rate In The Juvenile Red Eared Slider (Trachemys Scripta Elegans), Taylor Macdonald, Sarah Bouchard

Undergraduate Honors Thesis Projects

Specific dynamic action (SDA) is the energy expended during ingestion, digestion, absorption, and assimilation of a meal, and is influenced by meal (type, size, composition, and temperature) and environmental temperature. Understanding the effect of meal type and environmental temperature on SDA in turtles is important in describing how T. s. elegans may acclimate with changing environmental temperatures. In this study, we conducted feeding trials in which we fed juvenile T. s. elegans duckweed and mealworm diets at 25°C and 30°C. We measured the rate of oxygen consumption as a proxy for metabolic rate after feeding for four 30 minute consecutive …

Resisting The Western Scientist Inside And Outside Of The Collegiate Biology Classroom, Dulce G. Ventura , '22

Senior Theses, Projects, and Awards

In this thesis, I explore how conceptions of western science and scientists invade the Swarthmore Biology department and how it impacts BIPOC students inside and outside the classroom. The findings indicate that BIPOC students are routinely harmed by many ideas conceived from colonialism. However, both students and faculty demonstrate resistance inside and outside the classroom. Inside the classroom, faculty members build strong relationships with students in small communities and negate Western science's claim of objectivity. Outside of the classroom, programs like the Biology Big Sibling-Little Sibling program are recentering BIPOC students and their lived experiences, effectively creating a community where …

Ohio Anuran Gut Microbiomes, Serena Hoffman

Undergraduate Honors Thesis Projects

Recent studies focusing on the skin and gut microbiome of vertebrates have found how important microbiomes are to maintaining host health. Understanding the role the gut microbiome plays to host health is of great importance for conservation. Less is known about the gut microbiome than the skin microbiome for amphibians. Literature is especially lacking for local Ohio anuran species. The purpose of this study was to establish the baseline composition of the gut microbiome for local Ohio anurans and to determine whether host species or habitat is the best predictor of gut microbiome composition. Tadpoles were collected from seven different …

Representations And Perceptions Of Sexual Pleasure In Undergraduate Anatomy And Physiology (A&P) Courses, Brenda Kucha Anak Ganeng

Graduate Research Theses & Dissertations

The World Health Organization defines sexual pleasure as an important part of positive sexual experiences and sexual health. Despite its importance, sexual pleasure is often omitted from sexual health programming and curricula. Undergraduate human anatomy and physiology (A&P) courses serve as avenues where students who intend to go into health care learn foundational knowledge about human body systems and health; however, to our knowledge, there has been no documentation of if and how A&P students learn about sexual pleasure. A&P textbooks serve as an important resource for curriculum design and learning. I sought to answer the following research question: How …
