Presence Of Porcine Endogenous Retrovirus C In Domestic Pigs In Kansas, Avery Welton, Eric T. Gillock

SACAD: John Heinrichs Scholarly and Creative Activity Days

There is currently a shortage of organs available to perform allotransplants in humans, prompting the exploration of xenotransplantation as an alternative. Xenotransplantation is the transplantation of living tissues between different species, with porcine tissues being a promising option. However, concerns arise regarding cross-species transmission, particularly in relation to Porcine Endogenous Retroviruses (PERVs). PERVs are retroviruses that are integrated into the germ-line cells of pigs and are permanently embedded in the host cell’s DNA, allowing for vertical transmission. Of significant concern is the infectious nature of two PERV subtypes, A and B, to humans, which can potentially recombine with the third …

Screening Environmental Soil Samples For Antibiotic Production, Paige Mattick

SACAD: John Heinrichs Scholarly and Creative Activity Days

Antibiotic resistance is a detrimental worldwide challenge, producing bacterial infections that are progressively more difficult to treat and cure. To attempt to help alleviate this issue, we screened soil samples for the presence of antibiotic-producing microorganisms. Soil samples were collected and diluted to 1:100 and 1:1000 ratios of soil and distilled water. These soil mixtures were then streaked onto tryptic soy agar (TSA) plates and incubated at 30℃ until colonies developed. These colonies were then selected and plated on a lawn of Serratia marcescens, which was utilized as the target organism.

Serratia marcescens was selected due to its known resistance …

Anything But Another Essay: Understanding Undergraduate Stem Student Perceptions Of Creative, Project-Based Learning, Emily M. Redding, Lorelei E. Patrick

SACAD: John Heinrichs Scholarly and Creative Activity Days

The training of innovative and diverse scientists starts with creative teaching practices. Much of the pedagogy literature on incorporating nontraditional teaching practices in college STEM courses focuses on the use of in-class active learning activities. Less study has been devoted to creative, project-based assignments, such as “UnEssays”. The “UnEssay” is a semester-long assignment that challenges students to complete a library research project on a topic of their choosing and present it using anything but an essay. Although gaining popularity, few studies have assessed STEM student's perceptions of the assignments. To do so, Zoology students were asked to complete pre- and …

Roles Matter: Graduate Student Perceptions Of Active Learning In The Stem Courses They Take And Those They Teach, Lorelei E. Patrick, Leigh Ann Howell, Everett William Wischusen

Biological Sciences Faculty Publications

Despite many calls to reform undergraduate science, technology, engineering, and math (STEM) education to incorporate active learning into classes, there has been little attention paid to graduate level classrooms or courses taught by graduate students. Here, we set out to understand if and how STEM graduate students’ perceptions of active learning change in the classes they take versus those they teach. We found that graduate students had taken relatively few graduate level classes using active learning and they felt that more time should be devoted to active learning in the courses they were taking. Teaching assistants felt that they were …

Using A Self-Determination Theory Approach To Understand Student Perceptions Of Inquiry-Based Learning, Fangfang Zhao, Gillian Roehrig, Lorelei E. Patrick, Chantal Levesque-Bristol, Sehoya Cotner

Biological Sciences Faculty Publications

Inquiry-based laboratory activities, as a part of science curricula, have been advocated to increase students’ learning outcomes and improve students’ learning experiences, but students sometimes struggle with open-inquiry activities. This study aims to investigate students’ perceptions of inquiry-based learning in a set of laboratory activities, specifically from a psychological (i.e., Self-Determination Theory) perspective. Students’ ratings of the level of inquiry in these activities indicate that students’ perceptions of inquiry align with the instructor-intended amount of inquiry in each exercise. Students’ written responses, explaining their ratings, indicate that students’ perceptions of the amount of inquiry in a given lab exercise relate …

Graduate- And Undergraduate-Student Perceptions Of And Preferences For Teaching Practices In Stem Classrooms, Ngawang Gonsar, Lorelei E. Patrick, Sehoya Cotner

Biological Sciences Faculty Publications

Despite positive evidence for active learning (AL), lecturing dominates science, technology, engineering, and mathematics (STEM) higher education. Though instructors acknowledge AL to be valuable, many resist implementing AL techniques, citing an array of barriers including a perceived lack of student buy-in. However, few studies have explored student perceptions of specific AL teaching practices, particularly the perceptions of graduate students. We explored student-reported instructional strategies and student perceptions of and preferences for a variety of teaching practices in graduate and undergraduate classrooms across three STEM colleges at a large, public, research university. We found that both graduate and undergraduate students desired …

Building Excellence In Scientific Teaching: How Important Is The Evidence For Evidence-Based Teaching When Training Stem Tas?, Lorelei E. Patrick, Hillary A. Barron, Julie C. Brown, Sehoya Cotner

Biological Sciences Faculty Publications

Evidence-based teaching practices (EBTP)—like inquiry-based learning, inclusive teaching, and active learning (AL)—have been shown to benefit all students, especially women, first-generation, and traditionally minoritized students in science fields. However, little research has focused on how best to train teaching assistants (TAs) to use EBTP or on which components of professional development are most important. We designed and experimentally manipulated a series of presemester workshops on AL, dividing subjects into two groups. The Activity group worked in teams to learn an AL technique with a workshop facilitator. These teams then modeled the activity, with their peers acting as students. In the …

Adding Value To A Field-Based Course With A Science Communication Module On Local Perceptions Of Climate Change, Lorelei E. Patrick, Seth Thompson, Aud Halbritter, Brian J. Enquist, Vigdis Vandvik, Sehoya Cotner

Biological Sciences Faculty Publications

Field courses, while generally considered as beneficial for students, are challenging to implement and can lead to strained relationships between local residents and visiting scientists. Thus, it is critical to both maximize the educational value of field courses and help students develop contextualized science communication skills. We report on the development of a science communication module, integrated into an existing field-based ecology course, which aims to add value to an international field course enrolling students from multiple countries. Specifically, students surveyed local residents about their knowledge and perceptions of climate change, and then discussed their findings.

Perceptions Of Active Learning Between Faculty And Undergraduates: Differing Views Among Departments, Lorelei E. Patrick, Leigh Ann Howell, William Wischusen

Biological Sciences Faculty Publications

There have been numerous calls recently to increase the use of active learning in university science, technology, engineering, and math (STEM) classrooms to more actively engage students and enhance student learning. However, few studies have investigated faculty and student perceptions regarding the effectiveness of active learning or the barriers to its implementation. Previous work surveying a single class in a single department has suggested that faculty and students have different perceptions of the effectiveness of active learning strategies and the barriers faculty face when implementing these teaching strategies. We expand on these previous findings by surveying a larger and more …
