Me, Myself, And I: The Impact Of Metacognitive Strategies On Student Locus Of Control And Critical Thinking Skills, Danielle Kuchler

All Master's Theses

We live in an era when a college degree is essentially required for entry into good-paying careers, and yet achievement of a college degree is unacceptably low. Only 60% of students who enroll go on to graduate from 4-year colleges and universities in 6 years or fewer (National Center for Higher Education 2018). Why is this happening? What are the long-term intellectual and economic implications of ill-prepared students? We must ask ourselves if students are really prepared with the knowledge, skills, and dispositions to be successful in college and whether those attributes are developed while in college. Two of the …

Mathematics Cognitive And Content Abilities Across The Vincentian Student Population, Brendalee Rorena Cato

Walden Dissertations and Doctoral Studies

Mathematics achievement is a key component of student overall academic achievement. However, many students from Saint Vincent and the Grenadines (Vincentian students) continue to perform poorly on the regional Caribbean Secondary Examination Certificate (CSEC) mathematics examination. This poor mathematics performance is a concern for education stakeholders. The purpose of this quantitative, nonexperimental study was to explore the extent to which the CSEC mathematics scores of high-scoring Vincentian students versus low-scoring Vincentian students in the cognitive domains of knowledge, comprehension, and reasoning differ across the content domains of algebra; geometry; measurement; statistics; and relations, functions, and graphs (RFG). The theoretical foundation …

Teacher Perceptions Of Alternative Grading To Support Authentic Learning, Gina Nicole Sese

Walden Dissertations and Doctoral Studies

Alternative grading practices are often used in authentic learning environments where the focus is on connecting instruction to real-world issues, problems, and applications. Scholarly literature lacks research studies related to teacher perceptions of alternative grading to support authentic learning. The purpose of this basic qualitative study was to explore the perceptions of high school science teachers regarding their use of alternative grading to support authentic learning, student self-reflection, and student articulation of their learning. The conceptual framework for this study was based on Herrington and Oliver’s instructional design framework for authentic learning environments. The focus of the research questions was …

Computer science and cybersecurity have gained the attention of various stakeholders, industry representatives, educators, parents and students who are thinking about their future careers. Teaching computer science courses has moved into K-12 education, no longer introduced in the college classroom. There are various reasons for this trend. One is that in this way more children have access to the curriculum that integrates computer science principles, not just those undergraduate students in specific STEM majors. Other industries need different levels of computer science and cybersecurity education. There are various programs across the nation that are focusing on introducing these topics as …

Effects Of Synchronous Group Work On Learning And Community In Online Mathematics At Community Colleges, Carrie L. Naughton

All Graduate Theses, Dissertations, and Other Capstone Projects

Online learning plays an increasingly important role in community college education. However, evidence has shown that online learning can be a challenge, especially in mathematics, and students are not performing as well in online classes as they are in face-to-face formats. In addition, the online environment can be isolating and lonely, with little opportunity for interaction and group work with fellow students. With the increased demand for online mathematics courses at the community college level, it has become imperative that two-year colleges find ways to increase online student success while simultaneously fostering interaction, collaboration and community. This study focused on …

Mathematical Creativity And Problem Solving, Brooke Gruntowicz

Graduate Student Theses, Dissertations, & Professional Papers

Many mathematical problems can only be solved in routine ways. But when students see that problems can be solved in innovative, original, or novel ways, unexpected benefits arise such as development in one’s mathematical creativity. The general mathematics classroom must be reformed into a more perceptive atmosphere that challenges all students, where student mathematical creativity is fostered, and creative insights are encouraged. Mathematical creativity encourages the full development of the learner, all students on the spectrum from underchallenged to traditional. Mathematical creativity is the ability of "divergent production in mathematical situations, and the ability to overcome fixations in mathematical problem …

Use Of Calculators In High School Mathematics, Alex Mcdaniel

Williams Honors College, Honors Research Projects

For many collegiate level mathematics courses at universities across the country, students are not allowed to use calculators. This is often a huge adjustment for students who have spent their entire high school career using calculators. Whether it is graphing or simple arithmetic, students relied on calculators in high school, but for college, the tool of a calculator may not be available for them. This leads to a multitude of questions: Should calculators be used in high school? Do calculators help students learn or are they simply a tool to get answers? Are calculators beneficial in some courses, but not …

The Influence Of Connecting Funds Of Knowledge To Beliefs About Performance, Classroom Belonging, Dina Verdín, Jessica Smith, Juan Lucena

School of Engineering Education Graduate Student Series

First-generation college students in engineering accumulate bodies of knowledge through their working-class families. In our ethnographic data of first-generation college students, we identified tinkering knowledge from home and from work, perspective taking, mediational ability, and connecting experiences as knowledge sources brought to engineering. The purpose of this paper was to understand how first-generation college students’ accumulated bodies of knowledge (i.e., funds of knowledge) support their beliefs about performing well in engineering coursework, feeling a sense of belonging in the classroom, and certainty of graduating. Data for this study came from a survey administered in the Fall of 2018 from ten …

Improving Retention And Degree Attainment For Underrepresented Students In Stem: Is Experiential Learning The Solution?, Cori Henderson

Theses and Dissertations--Educational Policy Studies and Evaluation

Experiential learning opportunities, such as undergraduate research, are found to be useful in promoting retention and graduation in STEM majors, and specifically for underrepresented student populations. These opportunities are being implemented throughout the United Stated as a means to improve student learning and persistence. In Kentucky’s strategic plan, experiential learning activities are seen as an avenue to help students persist in college and are key components in helping the commonwealth reach their goal of sixty-percent of adult Kentuckians earning a college credential by 2030.

Mirroring the commonwealth’s strategic plan, Northern Kentucky University (NKU) emphasized the importance for experiential learning opportunities …

Tabletop Mechanical Tester, Jamie Dombroski, Brian English, Richard Leffler, Andrew Shirk

Williams Honors College, Honors Research Projects

The need for hands-on and face-to-face experiences in the engineering classroom is very great. The equations, principles, and concepts can all be learned, but without the visual and tactile application, these don’t always sink in or become concrete. A small-scale tensile test machine was designed, sourced, manufactured, and tested for the purpose of being applied in classroom settings to provide this experience to engineering students. Extensive research was performed concerning tensile machines on the market, the essential elements of which are the load cell, grips, crosshead, extensometer, motor, and frame. The raw materials for the frame were purchased and drawings …

Parent Involvement And Its Influence On Children’S Stem Learning: A Review Of The Research, Julie Thomas, Juliana Utley, Soo-Young Hong, Hunkar Korkmaz, Gwen Nugent

Department of Child, Youth, and Family Studies: Faculty Publications

A growing understanding that parents and teachers can effectively collaborate to help children succeed in school has led worldwide policymakers and school leaders to begin deliberate actions to increase parents’ participation in school life. For example, the Chilean Education Minister recently encouraged contracts between parents, schools, and the state to increase parental involvement. The Australian government has formed a Research Alliance for Children and Youth to develop and promote understanding of parent involvement (i.e., what it is, why it matters, how it influences learning) and to build evidence about what works. From a sociological perspective, a school’s organizational boundaries are …

Posters As An Effective Assessment Tool For A Capstone Course, David Gosselin, Doug Golick

Department of Entomology: Faculty Publications

A rubric was developed to assess student posters as a mechanism to evaluate learning outcomes for a senior capstone course. The analytic rubric allows for the efficient and systematic collection of data from posters by students who worked across a variety of disciplines including the physical, biological, Earth sciences, social science, and the humanities. The rubric effectively addressed a fundamental assumption and requirement put forth during rubric development, that is, it needs to be relatively easy to use without training while at the same time producing consistent results across evaluators. The overall Chronbach’s alpha of 0.80 across semesters indicates acceptable …
