Examining The Bifactor Irt Model For Vertical Scaling In K-12 Assessment, James Koepfler Dec 2012

Examining The Bifactor Irt Model For Vertical Scaling In K-12 Assessment, James Koepfler

Dissertations, 2014-2019

Over the past decade, educational policy trends have shifted to a focus on examining students’ growth from kindergarten through twelfth grade (K-12). One way states can track students’ growth is with a vertical scale. Presently, every state that uses a vertical scale bases the scale on a unidimensional IRT model. These models make a strong but implausible assumption that a single construct is measured, in the same way, across grades. Additionally, research has found that variations of psychometric methods within the same model can result in different vertical scales. The purpose of this study was to examine the impact of …


A Comparison Of Vibrotactile And Air Puff Stimulation For Inducing Swallowing, Kathryn Diane White May 2012

A Comparison Of Vibrotactile And Air Puff Stimulation For Inducing Swallowing, Kathryn Diane White

Dissertations, 2014-2019

The purpose of this study was to evaluate the effectiveness of two types of non-invasive, sensory stimulation on increasing the rate of swallowing and for inducing cortical activity associated with swallowing. The types of stimulation investigated were vibrotactile stimulation to the external throat area surrounding the laryngeal tissues and oral air puff stimulation to the anterior faucial pillars. A functional near infrared spectroscopy (fNIRS) system measured relative changes in the concentration of oxygenated hemoglobin (HbO) in cortical sensorimotor regions as an indirect measure of brain activity. The experiment included 16 healthy adult participants between the ages of 28 and 60 …


The Illusion Of Chaos: The Compositional Structure Of Olivier Messiaen’S Le Merle Noir, Tiana Lynn Grise May 2012

The Illusion Of Chaos: The Compositional Structure Of Olivier Messiaen’S Le Merle Noir, Tiana Lynn Grise

Dissertations, 2014-2019

When Olivier Messiaen submitted his work Le Merle Noir as the 1952 Paris Conservatoire examination piece for flute, he utilized a number of significant compositional techniques. At the time of its writing, Messiaen was in a phase of his oeuvre which included not only traditional methods of composition, but experimentation with more modern methods, such as dodecaphony, total serialism, and the use of birdsong as important thematic material. In Le Merle Noir, the amalgam of these methods results in a work that seems to have all of the wild and chaotic aspects of nature, but in reality has been painstakingly …


Headturn Preference Of 10-Month Infants For Familiar And Unfamiliar Signs, Steven Thomas Kulsar May 2012

Headturn Preference Of 10-Month Infants For Familiar And Unfamiliar Signs, Steven Thomas Kulsar

Dissertations, 2014-2019

Most deaf babies born in the United States are born into hearing families and show a developmental lag in spoken language acquisition, reading, writing, and social development when compared to deaf babies of deaf parents or hearing babies of hearing parents, due to limited language access. A modified headturn paradigm has been devised to assess infant preference to various familiar and unfamiliar ASL stimuli, to determine parallels between auditory-spoken and visual-spatial languages. If visual perception of first signs parallels auditory perception of first words, we would expect infants exposed to ASL as their native language to show a preference for …


Crisis Supervision: A Qualitative Study Of The Needs And Experiences Of Licensed Professional Counselors, Madeleine Ann Dupre May 2012

Crisis Supervision: A Qualitative Study Of The Needs And Experiences Of Licensed Professional Counselors, Madeleine Ann Dupre

Dissertations, 2014-2019

This qualitative study explored the supervision needs and experiences of licensed professional counselors working with clients in crisis. The primary purpose of the inquiry was to understand crisis supervision from the perspective of counselors in the field. The rationale for the study rested on three fundamental assumptions. First, counselors routinely encounter crises in their work with clients. Second, crisis response exposes counselors to hazardous situations and increases the risk for developing burnout, compassion fatigue, and vicarious traumatization. Finally, good supervision protects counselors from the risks associated with crisis work and enhances counselor self-efficacy. However, crisis supervision is frequently not provided …


Early Flute Pedagogy: The Utilization Of Alternative Types Of Flutes For Young Children, Erin Murphy May 2012

Early Flute Pedagogy: The Utilization Of Alternative Types Of Flutes For Young Children, Erin Murphy

Dissertations, 2014-2019

The typical practice in flute pedagogy is to start teaching the beginning flute student at approximately ten years of age. When compared to many other instrument disciplines, such as violin and piano, this is a relatively late starting age. The delay is primarily due to the large size and weight of the modern orchestral flute, as well as its lung capacity requirements. Not only do the physical limitations of the modern flute make early study difficult, but if disregarded, they also may pose health risks for the young beginner. This paper will discuss the importance of early childhood musical study …


Do Different Methods Of Hearing Aid Information Delivery Influence Knowledge Acquisition?, Lindsey Ann Parr May 2012

Do Different Methods Of Hearing Aid Information Delivery Influence Knowledge Acquisition?, Lindsey Ann Parr

Dissertations, 2014-2019

The main purposes of this study were to examine whether or not there was a difference in knowledge acquisition as a function of training method (these included: face-to-face session, DVD, and pamphlet); to determine which information included in hearing aid orientation was commonly known prior to training and which showed the most learning after training; and to evaluate which training method is the most popular among participants. A sample of 65 young college students with no prior hearing aid experience completed a pre- and post-multiple-choice test of hearing aid knowledge and gave their opinion of the hearing aid orientation immediately …


The Effects Of Age On The Mismatch Negativity Response To Differences In Place Of Articulation, Meredith Robotti May 2012

The Effects Of Age On The Mismatch Negativity Response To Differences In Place Of Articulation, Meredith Robotti

Dissertations, 2014-2019

The Mismatch negativity (MMN) response measures the auditory system’s response to change in stimulus. This measurement can be used to identify if the auditory system can physiologically discriminate two speech sounds. To date, studies that have recorded MMNs in response to differing place of articulation show conflicting data. One possibility for the conflicting results is due to the lack of carefully controlled stimuli. The purpose of this study was to evaluate the differences in amplitude and latency between adult and infant MMN responses when manipulating place of articulation for speech. Additionally, this study sought to determine if all adults showed …


Perceived Occlusion And Comfort In Receiver-In-The-Ear Hearing Aids, Sara A. Conrad May 2012

Perceived Occlusion And Comfort In Receiver-In-The-Ear Hearing Aids, Sara A. Conrad

Dissertations, 2014-2019

Purpose: In this study participants rated self-perceived occlusion and physical comfort for receiver-in-the-ear (RITE) hearing aids with different sizes of standard domes. Perceived occlusion was rated across listening and own voice conditions. Method: Twenty-one older adults with hearing impairment were fitted with bilateral RITE hearing aids and tested with three dome size conditions: open, plus, and power domes, and one control condition: the participants' own aids. Participants ranked self-perceived occlusion across the dome size conditions as well as across listening and own voice conditions, and also ranked level of physical comfort across dome sizes. Results: Self-perceived occlusion increased as dome …


Normal And Mutant Murine Auditory Brainstem Responses (Abrs), Kristin Shearer May 2012

Normal And Mutant Murine Auditory Brainstem Responses (Abrs), Kristin Shearer

Dissertations, 2014-2019

Spatial organization and topographic maps begin in the periphery and are preserved throughout the central auditory system. The Eph and ephrin family of signaling proteins is involved in the patterning and arrangement of auditory afferents which code information about frequency, intensity, and time. The present study utilizes the ABR as a physiological measure of the electrical potentials occurring in the brainstem following acoustic stimulation. We recorded this measure following click and tone pip stimulation in ephrin-B3 and EphA4 deficient mice at 2-3 months of age and compared them to wild type controls. Significant findings included elevated auditory thresholds, prolonged latency …


Demonstrating Validity Evidence Of Meta-Assessment Scores Using Generalizability Theory, Chris D. Orem May 2012

Demonstrating Validity Evidence Of Meta-Assessment Scores Using Generalizability Theory, Chris D. Orem

Dissertations, 2014-2019

Meta-assessment, or the assessment of assessment, can provide meaningful information about the trustworthiness of an academic program’s assessment results (Bresciani, Gardner, & Hickmott, 2009; Palomba & Banta, 1999; Suskie, 2009). Many institutions conduct meta-assessments for their academic programs (Fulcher, Swain, & Orem, 2012), but no research exists to validate the uses of these processes’ results. This study developed the validity argument for the uses of a meta-assessment instrument at one mid-sized university in the mid-Atlantic. The meta-assessment instrument is a fourteen-element rubric that aligns with a general outcomes assessment model. Trained raters apply the rubric to annual assessment reports that …


The Development Of The Well-Being Interview, Craig Alexander Asselin May 2012

The Development Of The Well-Being Interview, Craig Alexander Asselin

Dissertations, 2014-2019

Although psychologists and psychotherapists have long been concerned with the construct of well-being, currently there exist only self-report measures of the construct. This is potentially problematic because, as a number of researchers have pointed out, there are many different kinds of biases that can undermine the validity of data obtained from self-report measures. The purpose of this project was to develop a comprehensive, user-friendly, clinician administered interview to assess well-being. In order to accomplish this, the Well-Being Interview (WBI) was developed, based on recent developments in positive psychology (e.g., Diener (2000), Ryff (1995) and Seligman (2011) and theoretical unification (Henriques, …


Investigation Of Personal And Collective Mortality Threats In Individualistic And Collectivist Cultures: A Cross Cultural Study., Catherine Munns May 2012

Investigation Of Personal And Collective Mortality Threats In Individualistic And Collectivist Cultures: A Cross Cultural Study., Catherine Munns

Dissertations, 2014-2019

The purpose of this this study was to expand our knowledge of the ways in which people defend their worldviews under conditions of threat. Within the framework of Terror Management Theory (TMT), mortality salience (MS) in individualistic and collectivist cultures was investigated. Specifically, this study sought to directly examine MS effects as they relate to personal mortality and collective mortality. To accomplish this analysis, a 2 (Country: Russia and the U.S.) X 3 (Condition: Personal Mortality Salience, Collective Mortality Salience, and Control) design was employed. The current study consisted of undergraduate student participants from two cultures: U.S. and Russia. The …


Identity Development And The Construction Of Self: Findings And Implications From The Forum Bevi Project, Jessica Christine Spaeth May 2012

Identity Development And The Construction Of Self: Findings And Implications From The Forum Bevi Project, Jessica Christine Spaeth

Dissertations, 2014-2019

The current study focuses on factor analytic and correlational matrix data from the Forum BEVI Project (www.ibavi.org/content/featured-projects/), a national learning assessment initiative, with a particular emphasis on the “Identity Diffusion” scale from the Beliefs, Events, and Values Inventory (BEVI). Results suggest that the relative degree to which an individual is undifferentiated from his or her parents, experiences a foreclosed identity, and reports a troubled childhood is associated with a wide range of capacities and beliefs about self, others, and the world at large such as emotional expressiveness as well as environmental, cultural, and global concerns. Because Identity Diffusion is central …


J. S. Bach And The High School Choir: A Resource Guide For Teachers Of Intermediate And Advanced Level High School Choirs, Lynn G. Atkins Jr. May 2012

J. S. Bach And The High School Choir: A Resource Guide For Teachers Of Intermediate And Advanced Level High School Choirs, Lynn G. Atkins Jr.

Dissertations, 2014-2019

While familiarly with Bach’s well-known themes exists in the general aspects of contemporary lifestyle, providing exposure to the choral works of Johann Sebastian Bach (1685-1750) presents a particular challenge to the high school choral director. The purpose of this investigation is to provide a resource guide for the performance of choral masterworks of J. S. Bach at the high school level. For the purposes of narrowing this investigation, the following masterworks were reviewed: Magnificat, BWV 243; Mass in B Minor, BWV 232; Christmas Oratorio, BWV 248; St. John Passion, BWV 245; and St. Matthew Passion, BWV 244. A review of …


A Conductor's Analysis: The Birthday Cantatas Of Christoph Graupner (1683-1760), John Patrick Mccarty May 2012

A Conductor's Analysis: The Birthday Cantatas Of Christoph Graupner (1683-1760), John Patrick Mccarty

Dissertations, 2014-2019

Christoph Graupner (1680-1763), court composer and Kapellmeister for Landgrave Ernst Ludwig of Hessen-Darmstadt, was a prolific and highly regarded composer and an esteemed performer during his lifetime and was a contemporary and colleague of Telemann, Bach, and Handel. The quantity of Graupner’s works number among the highest of Baroque composers, with over 1,800 compositions. Much as his contemporary Johann Sebastian Bach (1685-1750), Graupner and his works were largely forgotten following his death. However, unlike Bach, whose music enjoyed a widespread revival during the early nineteenth century that continues to this day, the life and music of Christoph Graupner has remained …
