Implementing The Use Of Lesson Plan Templates Within The Mentorship Program For Dignity Health Hand Therapists, Ronell Matthew Sueno

UNLV Theses, Dissertations, Professional Papers, and Capstones

Occupational therapists (OT) have a wide range of specialties following graduation, one of which is hand therapy. This specialty requires a certain level of knowledge and clinical reasoning, especially concerning hand anatomy and physiology. It is hard to transition into hand therapy as a new occupational therapist due to extensive knowledge, additional patient-care hours, specialty certifications require, and lack of opportunity. A smoother transition into the workforce can be achieved through mentorship programs that allow for meetings with mentors to ask questions and get clarification on different treatments and diagnoses. This quality improvement project focused on gaining perspectives of hand …

Reconsolidation: Unique Cognitive Process Or State Dependent Learning?, Chris Kiley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Accessing a previously consolidated memory trace brings it back into a labile state where it must then undergo a re-stabilization process known as reconsolidation. During this process memories are susceptible to interference and may be updated with new information. Reconsolidation has been demonstrated in animals as well as in the procedural and episodic human memory systems. However, it is still unclear when the effect will occur. Some studies suggest that reconsolidation is only necessary when new information is presented in the same spatial context or when prediction error occurs. More recent work has provided evidence that reconsolidation could be due …

How Instruction, Math Anxiety, And Math Achievement Affect Learning A Novel Math Task: Evidence For Better Instruction, Amy Jane Mcauley

UNLV Theses, Dissertations, Professional Papers, and Capstones

The primary goal of this paper is to test how math anxiety, achievement, and instruction affect learning a novel math task. Currently, most research measures achievement and math anxiety on previously learned tasks. A two-part study was proposed to measure the effects of math anxiety on learning modular arithmetic (MA), a novel math task that involves subtraction and division. Participants of varying degrees of anxiety and achievement were randomly assigned to either a specific or vague instruction condition. Participants were either taught how to solve the task or given minimal information about how to solve the task. Before moving on, …

Change Deafness: A Comprehensive Examinations, Vanessa Claire Irsik

UNLV Theses, Dissertations, Professional Papers, and Capstones

Environmental changes are a vital source of information which can drive advantageous behavioral responses. For example, detecting visual changes can be critical when driving a vehicle or when simply walking down a busy street. Auditory perception is an essential complement to vision as it can allow awareness of changes in and out of sight. While subjective perception would suggest that our sensory representation of the world is complete, research on change deafness indicates that quite often the opposite is true. Healthy listeners often miss salient, suprathreshold auditory changes. Three separate manuscripts will be presented, each of which aims to advance …

More Bang For Your Buck: Bolstering Learning Via Refutation Text With Refutation-Based Elaborated Feedback, Jacqueline R. Cordova

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examines the effects of refutation text and refutation-based elaborated feedback on conceptual understanding, self-efficacy, interest, beliefs, attitudes, and knowledge, within the context of learning about climate change. The study also tests whether elaborated feedback moderates the refutation text effect through an interaction. One hundred and fifty nine undergraduate students were recruited to participate in this study, which was administered via computer. They completed measures of their self-efficacy and interest in learning about climate change, as well as climate change beliefs, attitudes, and knowledge. Approximately half of the participants read a refutation text and half read a comparison …

Comparing The Differences In Access To Professional Development For General Education And Special Education Teachers And The Subsequent Impact On Instructional Practice, Lori L. Slater

UNLV Theses, Dissertations, Professional Papers, and Capstones

The demands on schools, teachers, and students continue to increase as greater accountability measures are put into place at all levels. For teachers to meet these increased demands, it is important that they be provided opportunities to improve and enhance their content knowledge and pedagogy. One way to ensure the provision of these opportunities for teachers is through professional development. There is significant evidence that professional development can improve instructional practice and student outcomes (Drago-Severson, 1994; Garet et al., 2001; Guskey, 2000; Sparks & Loucks-Horsley, 1989; Wei et al., 2010; Zhang et al., 2015). However, there continues to be a …

An Investigation Of The Testing Effect On Motor Learning, Aaron Leonard Pauls

UNLV Theses, Dissertations, Professional Papers, and Capstones

Optimization of learning processes is the goal many educators strive to achieve with their students. One of the potential methods used towards optimizing this process is what’s known as the testing effect. The testing effect is the improved performance on a retention test as a result of prior testing during some period of practice. Previously, the testing effect was investigated using mostly cognitive tasks such as the learning of a number of words. In this paper, we examine the impact the testing effect has on learning the motor skill of putting. The study used a 2 x 2 mixed design, …

An Empirical Study On The Impact Of C++ Lambdas And Programmer Experience, Phillip Merlin Uesbeck

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lambda functions have become prevalent in mainstream programming languages, as they are increasingly introduced to widely used object oriented programming languages such as Java and C++. Some in the scientific literature argue that this feature increases programmer productivity, ease of reading, and makes parallel programming easier. Others are less convinced, citing concerns that the use of lambdas makes debugging harder. This thesis describes the design, execution and results of an experiment to test the impact of using lambda functions compared to the iterator design pattern for iteration tasks, as a first step

in evaluating these claims. The approach is a …

Effects Of Instructor Attractiveness On Classroom Learning, Richard Shane Westfall

UNLV Theses, Dissertations, Professional Papers, and Capstones

Although there have been multiple studies examining the effects of physical attractiveness on a variety of human interactions, one domain has been largely overlooked. The current thesis examined the effect of teacher attractiveness on a learning task. Specifically participants were exposed to a photograph that they believed was their instructor while listening to an audio lecture. Upon completion of the lecture participants then completed a forced choice recognition task covering material from the lecture. I hypothesized that participants would perform significantly better on the learning task when they perceived their instructor to be high in physical attractiveness. Neither the gender …

Implicit Theories Of Intelligence And Learning A Novel Mathematics Task, Nathan Oehme Rudig

UNLV Theses, Dissertations, Professional Papers, and Capstones

The social-cognitive model of motivation states that students adopt a theory of the nature of intelligence that guides their goals in academia and their responses to academic setbacks. Students who believe intelligence is an unchanging entity within them are more likely to adopt goals to display high ability, hide low ability, and respond helplessly to failed schoolwork. Conversely, a student who believes intelligence is a measure of effort and persistence will be motivated to gather knowledge and acquire new skills. The current study investigated the role theories of intelligence play in the field of mathematics understanding. In two experiments, participants …

The Formation Of Situation Models In Multimedia, Kris Gunawan

UNLV Theses, Dissertations, Professional Papers, and Capstones

When people read traditional text-based stories, they construct mental representations of the described state of affairs, called situation models, to connect various details of events (e.g., time, space, entity) in memory (Zwaan & Radvansky, 1998). According to the cognitive theory of multimedia learning (Mayer, 2005; 2011), stories presented as pictures and text generate independent channels of mental representations that can work hand-in-hand or separately to acquire and remember the materials presented. This dissertation consisted of two experiments that were used to further explore how the two modalities affect what is being mentally represented in memory. In Experiment 1, participants were …

Second Language Gesture And Acculturation In Study Abroad Contexts, Christie Marie Gardner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Motivationis an integral part of learning; Gestures are an important aspect of human communication, and culture plays a significant role in shaping all of these human elements. This study explores the relationship betweensocial, cultural-historical activityand second language(L2) gesture acquisitionas student motivations both drive, and emanate from, the L2 learning process. Six American students participating in a study-abroad program in Chile were evaluated at three different levels of L2 proficiency (beginning, intermediate, and advanced) for L2 gesture articulations and motivational developments. During the semester-long investigation, three audio-video recorded interviews were conducted to observe L2 gestural behaviors, and two e-mail logs were …

Examining The Testing Effect Using The Dual-Process Signal Detection Model, Nicole Jessica Bies-Hernandez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Taking a test can lead to enhanced long-term retention compared to not practicing the information or simply restudying, a finding known as the testing effect (Roediger, Agarwal, Kang, & Marsh, 2010). The current study examined whether the dual-process signal detection (DPSD) model (Yonelinas, 1994) offers an approach for investigating the testing effect across two experiments. Experiment 1 investigated if the DPSD model could be used to examine the testing effect, and it also examined a factor (i.e., the number of practice sessions) that influences the magnitude of the testing effect. Experiment 2 investigated whether making the final test dependent on …

A Study Of District Leadership Practices In The Principal Professional Learning Community, Danielle Grace Miller

UNLV Theses, Dissertations, Professional Papers, and Capstones

This qualitative study was implemented in an urban, Title I school district in the southern portion of the United States. The problem the study addressed was that the various phenomena pertaining to the implementation of the principal professional learning community (PPLC), as perceived by the 14 participating elementary school principals, had not been examined to determine their influence. Qualitative data were acquired from the principals through personal interviews.

Findings suggested that, with the regular opportunities for principals to share ideas and thoughts with their colleagues, PPLC participants perceived improved performance involving (a) the attributes of high skillfulness and high participation …

Construct And Criterion Validity Of The Rey Auditory Verbal Learning Test-Spanish Version In Adults With Traumatic Brain Injury, Cristobal Neblina

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Rey Auditory Verbal Learning Test (RAVLT) is among the most commonly used English-language neuropsychological tests of verbal learning and memory. Previous research supports the validity and clinical utility of adaptations of the RAVLT into many diverse languages. In the United States, Hispanics represent the largest and fastest-growing ethnic minority group. As the Hispanic populace continues to grow, so does the need for empirically validated Spanish-language neuropsychological measures. In 2002, a Spanish adaptation of the RAVLT was developed in Puerto Rico (Acevedo-Vargas, 2002). However, validation studies have not been undertaken with clinical samples, and little is known regarding its psychometric …

Affect Identification And Interpersonal Skills: An In-Depth Evaluation Of Social Cognition In Schizophrenia, Griffin Pollock Sutton

UNLV Theses, Dissertations, Professional Papers, and Capstones

The presence of deficits in various sub-domains of social cognition has been investigated to a degree in individuals with schizophrenia. Some of the most commonly researched and documented deficits have included impairments in the identification of affect portrayed in faces. Research has indicated that the performance of individuals with schizophrenia on such tasks is generally impaired as compared to normal controls. However, some have questioned the generalizability of such findings to real-world situations, as day-to-day interactions generally necessitate a constant, fluid assessment of the thoughts and feelings of others and are rarely, if ever, limited to still images of others. …

Enhancing The Calibration Accuracy Of Adult Learners: A Multifaceted Intervention, Antonio P. Gutierrez

UNLV Theses, Dissertations, Professional Papers, and Capstones

The present study employs the Nelson and Narens Model of Metacognition (NNMM) to examine the influence of metacognitive strategy training and extrinsic incentives on performance, level of confidence, and the calibration accuracy of undergraduate students' metacognitive judgments within a pretest/posttest experimental design. Calibration of performance is crucial because it allows learners to engage in appropriate comprehension monitoring during a learning episode. As metacognition implies, those individuals who are better calibrators can more adequately adapt to the demands of the situation (monitoring), and thereby better prepare for learning episodes that are similar in format or content (control). Consequently, this aids in …

Interactive Effects Of Working Memory Self-Regulatory Ability And Relevance Instructions On Text Processing, Nancy Jo Hamilton

UNLV Theses, Dissertations, Professional Papers, and Capstones

Reading is a process that requires the enactment of many cognitive processes. Each of these processes uses a certain amount of working memory resources, which are severely constrained by biology. More efficiency in the function of working memory may mediate the biological limits of same. Reading relevancy instructions may be one such method to assist readers in utilizing working memory resources more efficiently.

This study examines the relationship between perspective relevance instructions and participants' ability to regulate their working memory resources. In a 3 x 2 x 2 design the study extended the literature by utilizing a measure of fluid …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The present study examined the impact that dyad training with an emphasis on attentional focus has on learning in the performance of a golf putt. The participants were randomly divided into four dyad groups: dialogue and observation with external focus, dialogue and observation with internal focus, dialogue and no observation with external focus, and dialogue and no observation with internal focus. Participants were given a set of instructions to verbalize to their partners during practice. These instructions were designed to generate either an internal or an external focus. The results determined that those participants who were instructed to have an …

The Effect Of Goal Orientation Of Attention, Learning, And Metacognitive Awareness, Ordene V. Edwards

UNLV Theses, Dissertations, Professional Papers, and Capstones

An experimental study was conducted to examine whether achievement goals affect attention, comprehension, and metacognition. One hundred and twenty undergraduate students enrolled in introductory educational psychology classes participated. Students were randomly assigned to one of four goal groups (mastery, performance approach, performance avoidance, or control group) and one of three question groups (emotions, brain, and no questions). The study was conducted in two sessions. First, students were given a reading test, and questionnaires to measure their prior knowledge and personal goals. Second, students read the text on a computer. Then they completed an interest questionnaire, a manipulation check, a post …

Processes Of Disposition Development In K--5 Teachers, Deborah A. Obara

UNLV Theses, Dissertations, Professional Papers, and Capstones

Educators concur that teacher competency requires more than teaching knowledge and skills; competency requires appropriate professional dispositions. The development of professional dispositions is an expected outcome of teacher education programs. Since 2002, program accreditation has been contingent on documentation that prospective teachers have met national standards for dispositions. The body of educational research on disposition assessment has been growing. Research on disposition learning and development, however, has been impeded by the prevailing conceptualization of dispositions as fixed traits resistant to change. The present study conceptualized dispositions as malleable constructs within a theoretical framework that synthesized a cognitive model of thinking …

Learning In The Context Of Math Anxiety, Michelle Melissa Guillaume

UNLV Retrospective Theses & Dissertations

Previous studies have examined the effects of math anxiety on working memory and performance. It has been shown that having a high level of math anxiety not only decreases performance, but also interferes with working memory such that the anxiety competes for working memory resources, decreasing the amount of working memory resources available to work on a math task. Previous research has focused on the semantic memory approach, i.e., testing people on what they already know. The current study took this research one step further and looked at learning, specifically stimulus learning, in the context of math anxiety. A well …

The Effect Of Math Anxiety On Learning A Novel Math Task, Jeremy Adam Krause

UNLV Retrospective Theses & Dissertations

The focus of this experiment was to assess the effect of math anxiety on learning a novel math task (modular arithmetic). While participants that were low in math anxiety performed significantly better (in terms of reaction time) than participants that were in the medium and high math anxiety groups on repeated problems, the low math anxious participants did not perform differently than the medium and high math anxiety groups on unique problems. This indicates that the low math anxious participants were better able to learn the procedure of modular arithmetic but were not significantly different in their ability to learn …

On Breaking Ground: Second Language Literacy And Language Learning Through Sociocultural Practices, Ana Christina Iddings

UNLV Retrospective Theses & Dissertations

This study was concerned with (a) how second language children actually learn as a result of their social interactions; (b) the learning trajectory of second language students from apprentice to full participation in communities of practice; and (c) how this learning influences, and is reciprocally influenced by, the social, cultural, and historical context as learners become members of community practice. These questions were investigated under the lens of sociocultural theory, which emphasizes leaning in relationship with others and with materials over time within the social context; This was a qualitative study involving genetic methodology (Vygostky, 1981) which aims to understand, …

The Effects Of Feedback Protocol And Learning Environment Perceptions On Self -Regulated Learning, Kevin David Biesinger

UNLV Retrospective Theses & Dissertations

The current research investigated the effects of differing feedback protocols in a multimedia learning environment to determine if changes would occur over time in goal orientation, self-regulation, self-efficacy or achievement. Subjects from an traditional undergraduate chemistry course were assigned to either a norm-referenced or self-referenced feedback group. Goal orientation and self-efficacy were measured via self-report surveys pre-post instruction, self-regulation was measured as the cumulative number of times each subject opened a worked example/self-explanation prompt while engaged in weekly web-based quizzes, and achievement was measured using final semester course grades. Perceptions of the learning environment were also probed as a potential …

The Effects Of Mushroom Body Lobe Disruption On Learning And Memory, Brian S Dunkelberger

UNLV Retrospective Theses & Dissertations

Animal models have been used for centuries to study learning and memory in simple systems with many applications to humans (Chapter 1). The fruit fly Drosophila melanogaster has added greatly to our current understanding of learning and memory and its underlying biology (Chapter 2). The research described here focuses on the relationship between learning and memory and the brain using three mutant strains of flies: mushroom body miniature B (mbmB), small mushroom bodies (smu), and mushroom bodies reduced (mbr). Mushroom bodies are paired neuronal structures found in most invertebrate brains involved in learning and memory consolidation. All three mutations studied …

To determine the implementation of state assessment policy at the institutional level, this study's theoretical framework was implementation theory. The research questions which …

Instructional *Simulations And The Concepts Of Shared Cognition, Carolyn Sue Witt

UNLV Retrospective Theses & Dissertations

Graduates of registered nurse educational programs are expected to bring some degree of preparedness for intervening in emergency situations. However, within the clinical portion of the curricula a student may not have the opportunity to observe and or participate in patient respiratory or cardiac resuscitation. Volunteer participants, student nurses, engaged in practice with a human simulator (SimMan) and teacher guided dialogue to assist in the construction of nursing knowledge in a safe, supportive environment. SimMan was programmed with eight scenarios depicting common patient emergency situations. Simulations and debriefings were videotaped and transcribed. Post employment interviews were audio taped and transcribed. …

Development And Validation Of The Facial Affect Learning And Memory Test (Falmt) And Facial Identification Of Affect Task (Fiat), Christina Marie Armstrong

UNLV Retrospective Theses & Dissertations

The neurocognitive assessment of visuospatial memory has begun to receive attention and has been recognized as being important in the understanding of overall memory processing. Additionally, there has been an increased emphasis on emotion processing, particularly affect discrimination and attention bias. However, little information is currently available on learning and memory for emotional information. Because emotion is expressed to a large extent through nonverbal means, a nonverbal test of emotion learning would be valuable, although no such test currently exists. The aim of the current study was to establish normative performance characteristics, convergent and divergent validity for two newly developed …
