Experiences Of Undergraduates And Graduate Teaching Assistants In Biology Course-Based Undergraduate Research Experiences, Emma Crystal Goodwin Aug 2021

Experiences Of Undergraduates And Graduate Teaching Assistants In Biology Course-Based Undergraduate Research Experiences, Emma Crystal Goodwin

Dissertations and Theses

Evidence of positive student outcomes from course-based undergraduate research experiences (CUREs) has sparked implementation of CUREs in introductory biology laboratory courses, as one approach to boosting student engagement in research. In a CURE, students collaborate with other students and instructors on a research project, where they conduct novel scientific research that has relevance to a local or scientific community. However, previous research rarely considers that graduate teaching assistants (GTAs) often teach introductory labs. The classroom role of GTAs expands in a CURE--they no longer need to simply teach a lab class, but also to serve as research mentors. GTAs, who …


Short- And Long-Term Impacts Of A Deliberative Pedagogy In Introductory Biology And Chemistry Courses, Liz Rain-Griffith Jul 2020

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 …


Examining Integration And Sense Of Belonging Among Undergraduate Students Participating In Stem Support Programs, Mackenzie J. Gray Mar 2020

Examining Integration And Sense Of Belonging Among Undergraduate Students Participating In Stem Support Programs, Mackenzie J. Gray

University Honors Theses

National calls have been made to strengthen our nation’s Science, Technology, Engineering, and Mathematics (STEM) workforce by improving student preparation and increasing retention rates. A sense of belonging in STEM fields is thought to be key for persistence in STEM, but many students face academic, social, and financial barriers that can impede this sense of belonging. These barriers can be more pronounced for students underrepresented in STEM. In response, many federal and non-governmental agencies have invested in the future STEM workforce by funding STEM support programs. Such programs aim to support student persistence by providing academic, social, and financial resources …
