A Causal Comparative Study Of Stem Persistence Between Supported And Non-Supported Stem Interested Students, Elizabeth Bernardi

Electronic Theses and Dissertations

Many students who enter a STEM track in college move out of that track before graduation (National Science Foundation, 2018). The purpose of this study was to assess whether there was a difference in STEM-related major persistence for population proportions of students actively involved in the Science Scholars program and those who were STEM-interested but not program participants. This program oriented students to the STEM program, facilitated engagement with peers and faculty, exposed students to research opportunities, and filled in potential learning gaps (Gibson et al., 2019).

The questions guiding the current research included:

Q1. Was there a statistically significant …

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 …

Investigating The Relationship Between Departmental Support Structures, Self-Efficacy And Intention To Persist: An Examination Of Students' Experience In 19 Physics Graduate Programs Across The United States, Diana Sachmpazidi

Dissertations

Science, Technology, Engineering, and Mathematics (STEM) graduate programs experience consistently high attrition rates. Moreover, persistent disparities exist in racial and gender representation. Women and People of Color are significantly underrepresented and have higher attrition rates than men and white and Asian American students. To date, little work is done to understand graduate student attrition or persistence. There is also a lack of information regarding the causes of demographic disparities in attrition. Most past studies in this context have focused on students' attributes, undergraduate preparation, and mentoring relationships. Moreover, student self-efficacy is a contributing factor for undergraduate student retention. Yet, there …

Comparing Effectiveness And Perceived Characteristics Of Active Learning Methods In Undergraduate Biology Education, Linda R. Pesciotta

Dissertations - ALL

Although many undergraduates begin college as STEM majors, attrition rates from the field are high and numerous reports suggest that evidence-based teaching methods are critical for retention. Despite educators' research and near consensus that active learning is more effective than lecture, there are many types of active learning and the literature indicates their effects are not equivalent. The purpose of the current study was to directly compare different kinds of active learning by assessing their correlation with student performance (including learning gains) and understanding students' perceptions of them (including whether they contained Merrill's five principles of instruction and/or met three …

This study provides the statistical analyses of the survey data completed by 283 senior engineering students on their perceptions about their levels of involvement related to positive/negative outcomes students perceive and affective engagement. Data results showed all levels of involvement have a significant influence on positive outcomes. Besides, active involvement degree, hours, and types of …

Student Perceptions Of The Online Introductory Biology Laboratory Curriculum Using A Framework Of Vision And Change And Its Core Competencies, Erin Ulrich

Masters Theses/Capstone Projects

In response to the COVID-19 pandemic, an Introductory Biology course at a private university was reformatted to an online format. To examine student perceptions of the effectiveness of the laboratory portion of the course, a researcher designed questions based on the Vision and Change core competencies and presented them to a representative sample of students in virtual interviews. The themes which emerged from the student responses were that students had positive views of their comfort level with the scientific method, the virtual laboratory synchronous format, worksheet activities, breakout rooms, and lessons with social relevance to college-aged students.

Mindfulness & Mindset: The Winning Combination? The Exploration Of The Unstuck Method® On Developmental Math Students: A Mixed Methods Study, Edite Birnbaum, Edith L. Birnbaum

Graduate Theses & Dissertations

Many students enter colleges having to take non-credit-bearing courses, and many do not pass these courses due to numerous factors, including anxiety and stress, especially in mathematics. Current literature shows how mindfulness-based interventions (Bamber, & Schneider, 2016; Dvořáková et al., 2017; Hidman, 2013; Miller et al. 2019; Regehr et al., 2013) and a growth mindset (Blackwell et al., 2007; Boaler et al., 2018; May, 2009) have a positive effect on student stress, anxiety, and academic success. This mixed-method study focused on the unSTUCK strategy’s impact, a mindfulness-inspired tool, on foundation math students. The unSTUCK strategy is a mindfulness-inspired program. The …

The Efficacy Of Accelerating Underprepared Community College Students Using A Corequisite Liberal Arts Mathematics Course, Drew Wilkerson

Theses and Dissertations--Educational Policy Studies and Evaluation

Every year, millions of first-time students enroll in community colleges underprepared for college-level work in mathematics. Typically, these students are referred to a sequence of developmental courses designed to remediate their skills and prepare them for college-level work. Recently, educators and policy makers have questioned the efficacy of these courses, especially since most students assigned to remedial courses never complete the sequence and enroll in college-level courses. Calls to reform developmental mathematics have included changes to how institutions determine whether students are college-ready and the elimination of the remedial course sequences themselves. The corequisite model, in which students enroll in …

Proctoring And Apps In College Algebra, Cynthia M. Shelton

Theses and Dissertations--Education Sciences

The pandemic forced more instructors and students to move to online learning. For the first time, many experienced a loosening of the reigns and were forced to allow students to submit non-proctored work. Many may have questioned what students really learned in the year 2020. Many college math course competencies emphasize procedures. Now that apps can do that for students, where does that leave math instructors? Additionally, online instruction has exploded over the last decade and has challenged the teaching of college mathematics. While online instruction opens the door to access, it does beg the question of whether students complete …
