How Do Beliefs Come Into Play? An Examination Of The Influence Of Core Conceptions On Science Teachers’ Inquiry Lesson Plan Designs, Mehmet Fatih Dulger

UNLV Theses, Dissertations, Professional Papers, and Capstones

Teaching science through inquiry-based methodologies has been advocated by several governmental and professional organizations (National Research Council [NRC], 2000; NGSS Lead States, 2013); however, their use is not widespread. Why is this? What science teachers do in their classrooms is shaped by their beliefs, especially their beliefs about the nature of science, about the goals and purposes of school science and the goals of teaching science, and about the teaching and learning science. By critically examining these core conceptions and their influence on teacher lesson planning, this study aims to shed light on the role conceptions play when teachers design …

The Experience Of Self-Coherence: Self-Coherence As The Hub Of All Needs, April Ursula Fox

UNLV Theses, Dissertations, Professional Papers, and Capstones

Self-coherence as the hub of all needs is a novel proposition made by Carol Dweck (2017), and not yet further explored. While supporting self-coherence with a comprehensive review of its presence within behavioral sciences, Dweck does not dive deeper into it, and offers an invitation for further research of its workings. In this study I respond to that invitation. I design a continuation to her theory. I also expand her theory to include what I have found to be missing, but essential, additional components that cannot be ignored within the context of self-coherence as a master sensor of needs. Finally, …

What Do General And Organic Chemistry Students Consider When Making Decisions About Acids And Bases? A Phenomenographic Study, Sarah Wood

UNLV Theses, Dissertations, Professional Papers, and Capstones

Chemistry students often struggle in organic chemistry courses. In fact, these courses are viewed by some as “weed-out” classes. There are many fundamental concepts covered in general chemistry that contribute to students’ ability to succeed in organic chemistry. One of those fundamental topics, and the focus of this study, is the topic of acids and bases. Acid–base topics are featured in both general and organic chemistry courses, and the interests of this study lie not only within the realm of organic chemistry but also general chemistry.

Relationships Between Mindfulness, Nonacademic Factors, Stress, And Test Performance: A Cross-Sectional Study, Rebecca A. Baumeister

UNLV Theses, Dissertations, Professional Papers, and Capstones

Successful test performance is essential to nursing students. Poor performance comes with consequences such as inability to progress or removal from the program, leading to attrition. The influence of academic factors on test performance have been widely researched and stress is known to hinder it, yet other factors may also impact test performance.

Dispositional mindfulness has the potential to support test performance, but no known studies have focused on these two variables among undergraduate nursing students. A gap also exists in relation to the influence of nonacademic factors on undergraduate nursing students’ test performance. Due to the ongoing nursing shortage, …

Teaching A Communication Protocol Via Graduated Guidance On The Ipad To Assist In Functional Communication Training For Nonverbal Children With Asd, Janelle Saunders

UNLV Theses, Dissertations, Professional Papers, and Capstones

Non-verbal children with Autism Spectrum Disorders (ASD) often struggle with functional communication, and are often not able to express their wants, needs, emotions, or engage in meaningful conversations (Hudry et al., 2010; Luyster et al., 2008; Weismer et al., 2010). Picture exchange systems as well as AAC devices (e.g., the iPad) have emerged as viable options to teach this population how to communicate effectively (Charlop-Christy et al., 2002; Couper et al., 2014; Dogoe et al., 2010; Ganz et al., 2015; Greenberg et al., 2012; Logan et al., 2017).

An Orchestral Percussionist's Guide To Instruments Of The Caribbean, Lucas Brust

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sparked by the introduction of Janissary percussion into the works of the First Viennese School, composers have been steadily expanding the musical responsibilities and tonal palette of the orchestral percussion section. Most institutions of higher education extensively address the traditional orchestral percussion instruments and only relatively recently have these institutions begun incorporating the more “exotic” percussion instruments from various indigenous musical traditions. With the resources and proposed performance practices suggested in this document, orchestral percussionists can gain the knowledge and familiarity to identify the instruments by name and construction, demonstrate fluency in technique and sound production, and display basic understanding …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The role of admissions counselors has become pivotal to the mission of enrollment management in higher education. Admissions Counselors have evolved from serving as personnel that provides counseling to students to one that expands to include marketing to concurrent high school classes and students. As a result, the discipline has seen an increase in the number of counselors entering the workforce and has experienced a steady progression of career opportunities and advancement in the field of admissions (Phair, 2014). Nonetheless, college graduates are more likely to apply for these positions though limited support for career advancement exists due to these …

Understanding And Addressing Preservice Elementary Teachers’ Misconceptions In Science Education, Nicole Juliana Thomas

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prior research has demonstrated that both children and adults alike hold misconceptions about various scientific phenomena (Snyder & Sullivan, 1995; Driver et al., 1985). These misconceptions range from a variety of different fields, including astronomy and space science, environmental biology, and geology, among others (Miller & Brewer, 2010; Wandersee et al., 1994; Ritger & Cummins, 1991). Research suggests that the vast majority of misconceptions are formed early in a students’ educational career, and these misconceptions could be held throughout adulthood unless they are sufficiently addressed (Coley & Tanner, 2012; Posner et al., 1982; Nehm & Reilly, 2007; Sadler et al., …

Implementation Of A Protocol In The Freestanding Emergency Department To Screen For And Identify Possible Victims Of Human Trafficking, Joe Alvarado

UNLV Theses, Dissertations, Professional Papers, and Capstones

Human trafficking (HT) victims often seek medical care in the emergency room setting. In a recent study among HT survivors, 88% attested to receiving medical care while in captivity, with 63% treated in the emergency care setting. Freestanding emergency departments typically have lower acuity and lower patient volumes than hospital-based emergency departments. This setting creates shorter wait times and minimizes the length of stay at every point during the emergency room experience. For traffickers, this is an ideal situation if their victim needs medical attention, and they want to get in and get out of the emergency room with less …

Finding Ways To Increase Physical Activity In Students With Disabilities In A Social Distanced World, Paula Kerchenski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Obesity in the United States is becoming a problem that negatively affects the life expectancy of young children, which for the first time in history is moving in the wrong direction (Ogden et al., 2014). According to obesity trend data, obesity has tripled in children from 5% in 1978 to 18.5% in 2016 (Anderson et al., 2019). For our students with disabilities, obesity rates are two times higher than students without disabilities (Neter et al., 2011).
