Eight Steps To Weight Loss: Development Of An Evidence-Based Collaborative Provider-Patient Workbook For Overweight Or Obese Adults, Katherine Ann Wagner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Despite decades of effort on the part of health care providers and policy makers to reduce the prevalence of obesity, the prevalence of obesity in the United States remains high (CDC, 2015). In the adult population ages 20 years of age and older, 35.7% are considered obese. The annual medical costs for people who are obese are $1,429 higher than people of a healthy weight (CDC, 2013). Obesity increases the risk for chronic health conditions such as hypertension, type 2 diabetes, hypercholesterolemia, coronary heart disease, stroke, asthma, arthritis, and cancer (Hammond & Levine, 2010). Over-weight and obesity are the main …

Guiding Sixth Grade Language Development In Mathematical Content Acquisition Through Student Centered Siop Instruction, Leah Callister

Dissertations, Masters Theses, Capstones, and Culminating Projects

Mathematics is considered a universal language for students. However, now common core standards require students to explain their conceptual understanding through words, numbers, and verbal explanations. Student proficiency in the universal language is impeded when they do not speak the primary language. It is difficult for the teacher to teach both the academic language and mathematical concepts, when the vocabulary is not accessible to all students. Conversely it is difficult for students to follow the pacing of the class while having to translate and gain a conceptual understanding of the subject. The purpose of this study is to increase student …

Eighth Grade Mathematics Intervention: Improving Student Self-Esteem And Content Knowledge Of Targeted Mathematic Skills, Stephanie Hart

Dissertations, Masters Theses, Capstones, and Culminating Projects

By eighth grade some students believe they are “not good” and never will be successful at mathematics. Discouraged by poor grades, negative feedback from teachers or demoralized by repeated academic failure, these students disengage from their mathematics classwork. In some cases, mathematics intervention classes are a last chance to get them back on track to qualify for Algebra I in 9^th grade. The purpose of this study is to identify strategies to reengage students by increasing their academic content knowledge in mathematics and boosting their self-esteem and sense of belonging in the school setting. The review of the literature …

A Modularized Tablet-Based Approach To Preparation For Remedial Mathematics, Kenneth A. Parker

Publications and Research

Basic arithmetic forms the foundation of the math courses that students will face in their undergraduate careers. It is therefore crucial that students have a solid understanding of these fundamental concepts. At an open- access university offering both two-year and four-year degrees, incoming freshmen who were identified as lacking in basic arithmetic skills were engaged in an experimental technology-enhanced workshop designed to provide them with a deeper understanding of arithmetic prior to their initial remedial coursework. Customized online content was created specifically for this experiment, and the first implementation (n=27) yielded statistically significant improvement, not only from pretest to post- …

Supplemental Action Learning Workshops: Understanding The Effects Of Independent And Cooperative Workshops On Students’ Knowledge, Kathryn M. Morris

Dissertations

Community colleges enroll more than half of the undergraduate population in the United States, thereby retaining students of varying demographics with extracurricular demands differing from traditional four-year university students. Often in a collegiate lecture course, students are limited in their abilities to absorb and process information presented by their instructors due to content-specific cognitive gaps between the instructor and the student (Preszler, 2009). Research has shown implementation of instructor-facilitated action learning workshops as supplemental instruction may help bridge these cognitive gaps allowing better student conceptualization and dissemination of knowledge (Drake, 2001; Fullilove & Treisman, 1990; Preszler, 2009; Udovick et al., …

Structural-Symbolic Translation Fluency: Reliability, Validity, And Usability, Matt C. Hoskins

Electronic Theses and Dissertations

Standardized formative mathematics assessments typically fail to capture the depth of current standards and curricula. Consequently, these assessments demonstrate limited utility for informing the instructional implementation choices of teachers. This problem is particularly salient as it relates to the mathematical problem solving process. The purpose of this study was to develop and evaluate the psychometric characteristics of Structural-Symbolic Translation Fluency, a curriculum-based measure (CBM) of mathematical problem solving. The development of the assessment was based on previous research describing the cognitive process of translation (Mayer, 2002) as well as mathematical concept development at the quantitative, structural, and symbolic levels (Dehaene, …

Evaluating College Biology Laboratory Accommodations For Students With Blindness And Visual Impairments, Barbara Rae Heard

All Theses And Dissertations

Studies show that active participation in science laboratory activities promotes student learning. However, students with blindness and visual impairments (BVI) often confront obstacles to active participation in the required activities of the college biology laboratory. Legislation requires institutions of higher education to provide accommodations for students with disabilities, yet the institutions must also maintain the academic integrity of their courses and programs. While college biology instructors provide specific accommodations, such as tactile models and audible devices, to enable active participation by students with BVI, they do so without research-supported guidelines for best practices. This mixed methods study sought to evaluate …

Teaching Numerical Methods In The Context Of Galaxy Mergers, Maria Kourjanskaia

Physics

Methods of teaching numerical methods to solve ordinary differential equations in the context of galaxy mergers were explored. The research published in a paper by Toomre and Toomre in 1972 describing the formation of galactic tails and bridges from close tidal interactions was adapted into a project targeting undergraduate physics students. Typically undergraduate physics students only take one Computational Physics class in which various techniques and algorithms are taught. Although it is important to study computational physics techniques, it is just as important to apply this knowledge to a problem that is representative of what computational physics researchers are investigating …

Academic Intervention: Acceleration And Remediation, Barbara Franklin

Doctoral Dissertations and Projects

Eighth grade math students must pass a standards based test to be promoted to the next grade. Students who were at risk of failing the state’s annual test faced impending retention. The purpose of this quasi-experimental study was to see if an intensive nine-week (55 min per day) remedial Math Connection (MC) class for 67 suburban, eighth grade students identified as at risk of failing, could significantly increase the scores; concurrently, at this Title I school, they were compared with 122 eighth grade students who were not identified as at risk of failing. The dependent variable was measured using the …

Facilitating Conceptual Learning In Quantitative Chemistry, Sarah R. Johnson

Electronic Theses and Dissertations

Traditional chemistry laboratory courses have a manual consisting of “step-by-step” experiments; instructions are given to complete experiments, requiring minimal information/concepts processing to be successful. This experience leaves students unprepared for the real-world, where critical thinking skills are needed to conduct research. This study focused on building analytical techniques, conceptual knowledge, and critical thinking skills used to solve research problems. A new quantitative chemistry laboratory manual was developed to transition students from traditional to inquiry-based experiments, requiring analytical method development. Data showed students having less difficulty using the new manual (0.8281 average difficulty) on method development exam questions and experiments, compared …

Retention Effects Of An Experiential Pedagogical Approach, Kelsea E. Adams

Senior Honors Projects

The quality and nature of delivery of education, especially at the K12 level is a major focus of the education reform movement. As an aspiring teacher, I am interested in developing a personal understanding of the efficacy of different modes of delivery. A large body of studies has examined the differences between experiential learning versus traditional classroom learning as well as effects on student retention. Traditional classroom learning involves literary texts, PowerPoint presentations and teacher-centered learning. In contrast, experiential learning is a hands-on, real world experience that provides students with an environment to expand their critical thinking skills and apply …

Multivariate Thinking In An Intro Stats Course – Is It Possible?, Beverly Wood

Publications

Many of our students have an intuitive sense that there is more to the story than univariate or bivariate data can tell us. We can acknowledge and encourage that habit of digging deeper by demonstrating some ways to look at additional variables. Simpson’s paradox and side-by-side scatter plots are ways to provide a glimpse of more complex analysis that are accessible to students in an introductory course with or without strong quantitative skills.

The goal of this study is to explore and characterize the effects of using a dynamic graphing utility (DGU) on conceptual understanding and attitudes toward mathematics, measured by the responses of college algebra students to an attitude survey and concepts assessment. Two sections of college algebra taught by the primary researcher are included in the study, with one group using the dynamic graphing utility Desmos (www.desmos.com), and the other using the TI-84 (or equivalent) graphing calculator as a control. The Precalculus Concept Assessment (Carlson, Oehrtman, & Engelke, 2010) was used to measure aspects of students’ conceptual understanding of course material, …

Designing Sewn Circuits And Stem Self-Efficacy In Middle School Girls, Kara Kaiser

Graduate Theses and Dissertations

The purpose of this study is to determine if the experience of designing and sewing LilyPad Arduino circuits in crafts projects can increase middle school girls’ STEM self-efficacy. Boys STEM self-efficacy will also be assessed to determine if LilyPad Arduino circuits can also increase boys’ STEM self-efficacy. Researchers have been wondering why there is a male dominance in STEM (science, technology, engineering and mathematics) fields and why some women do not have a particular interest in these subjects. There are several reasons this could happen; stereotypes conveyed to them by parents and/or teachers, they genuinely are not interested in STEM …
