The Triptych Tetrad: Marshall Mcluhan's Neo-Medieval Communication Theory, Anthony Wachs

Electronic Theses and Dissertations

The work of Marshall McLuhan has often been reduced to the form of catchphrases and "McLuhanisms," such as the "global village" and "the medium is the message" in the field of communication. Though these phrases capture an aspect of his thought, the scholarly understanding of McLuhan's vision remains incomplete, even within the specialized area of Media Ecology, of which McLuhan is recognized as the intellectual father. Throughout his corpus, McLuhan makes reference to the classical and medieval trivium, which was the basis for education throughout Western history until the Renaissance. Indeed, he developed a history of the trivium up to …

At the end of the two week observation period students participated in an exit interview focused on their perceptions of student engagement. The student …

Affective Response Of African American And European American Students To Portrayals Of Cross-Racial Relationships On Television, Earl S. Mowatt

Electronic Theses and Dissertations

Race is a potent discourse within the world of pop culture, particularly in television where viewers are witnessing more racial diversity in scripted shows. However, show creators must maintain standards that emphasize distinct social roles among characters in order to appeal to large heterogeneous audiences. These roles tend to be characterizations of racial stereotypes that often lead to biased opinions and inaccurate perceptions of minority groups. Previous studies detail that racial biases in media adversely shape public opinions about African Americans and depress the desire for racial integration. This seems somewhat confounding since the shift in programming towards racial diversity …

Development Of The Tagalog Version Of The Western Aphasia Battery-Revised, Carmina Ozaeta

Electronic Theses and Dissertations

There has been limited research done in the Philippines in the area of aphasia, a frequent concomitant symptom of strokes and presents as impairment in any area of the input and output of language. Diagnosis is generally conducted by clinicians based on sites of lesion of speakers with aphasia and clinical observations of language symptoms and unpublished translation of the WAB. The lack of relevant research and formal assessment tools in the Philippines motivated this current study. The development of this type of assessment battery for the Tagalog (pronounced /təˈɡɑːlɒɡ/ in English) speaking population will provide a means for differential …

A second goal was to understand any potential relationships between intensive reading teachers’ practical knowledge and formal knowledge. These two goals framed the study’s three research questions. To answer these three questions, the study was conducted in two phases. Phase one included 32 participants, all of whom worked in the role of a K-2 intensive reading intervention teacher. Each of these 32 participants completed a background …

Tier I Rti For English Language Learners With Language Deficits, Maria Jose Soong

Electronic Theses and Dissertations

Educators are attempting to eliminate the disproportionate representation of culturally and linguistically diverse students in special education through initiatives such as Response to Intervention (RtI). Prior to the implementation of such initiatives, existing research relevant to this population must be critically reviewed and expanded. A synthesis of the available literature can provide significant insight into the type of data necessary to make informed decisions involving English language learners (ELL) at Tier I of an RtI model. In forming the theoretical foundation for this research, cognitive deficits associated with language-based disabilities and principles of cognitive load theory were examined. The study …

The Impact Of Access To Books On The Reading Motivation And Achievement Of Urban Elementary Students, Lee-Anne Spalding

Electronic Theses and Dissertations

The focus of this research was to study the association that reading motivation and reading achievement have with increased access to books provided by the non-profit program Book Trust, could have on urban elementary students, specifically second graders being educated in a large school district in Central Florida. Teacher data collection sheets, the Motivation to Read Profile (MRP): Reading Survey and the Florida Assessment for Instruction in Reading (FAIR) were used to measure the aforementioned associations. Findings revealed that increased access to books in these elementary schools did not have a statistically significant impact on reading motivation or reading achievement …

An Analysis Of Communication Anxiety And Reading Comprehension In Sixth, Seventh And Eighth Grade Students, Tami Mullens Davis

Electronic Theses and Dissertations

The goal of this research was to determine whether communication apprehension impacted reading comprehension in sixth, seventh, and eighth grade students and to examine the impact of family socio-economic status. Many studies have demonstrated the negative relationship between communication apprehension and academic achievement, however, studies of elementary and middle school students have been conspicuously missing from this research. Findings of this study indicated that the levels of communication apprehension rose slightly as grade level increased. Results showed that females in the study had higher levels of communication apprehension than males. The study also found that those students receiving free and …

Evaluating Improvisation As A Technique For Training Pre-Service Teachers For Inclusive Classrooms, Theresa Becker

Electronic Theses and Dissertations

Improvisation is a construct that uses a set of minimal heuristic guidelines to create a highly flexible scaffold that fosters extemporaneous communication. Scholars from diverse domains: such as psychology, business, negotiation, and education have suggested its use as a method for preparing professionals to manage complexity and think on their feet. A review of the literature revealed that while there is substantial theoretical scholarship on using improvisation in diverse domains, little research has verified these assertions. This dissertation evaluated whether improvisation, a specific type of dramatic technique, was effective for training pre-service teachers in specific characteristics of teacher-child classroom interaction, …

Investigation Of Tactile Displays For Robot To Human Communication, Daniel Barber

Electronic Theses and Dissertations

Improvements in autonomous systems technology and a growing demand within military operations are spurring a revolution in Human-Robot Interaction (HRI). These mixed-initiative human-robot teams are enabled by Multi-Modal Communication (MMC), which supports redundancy and levels of communication that are more robust than single mode interaction. (Bischoff & Graefe, 2002; Partan & Marler, 1999). Tactile communication via vibrotactile displays is an emerging technology, potentially beneficial to advancing HRI. Incorporation of tactile displays within MMC requires developing messages equivalent in communication power to speech and visual signals used in the military. Toward that end, two experiments were performed to investigate the feasibility …

Cultivating A Rainbow Median Through The Study Of Sexuality In Second Language Acquisition: Identity Construction Of Lesbian Women Native To The Southern Region Of The United States, Elizabeth Walker Graves

Electronic Theses and Dissertations

Despite diverging theories concerning the dissimilarities between male and female speakers, there is a general consensus that there is relevance in the relationship between gender and language, especially when considering the sociolinguistic effects of gender in second language acquisition and for the L2 learner. While there is a wealth of publications dedicated to examining the relationship between gendered roles and language, the idea of superseding the study of gender roles with a more comprehensive and considered study of gender identities has not been as forthcoming until very recently. Furthermore, there is little significant research into the relationship between gender identity …

An Analysis Of Down Syndrome Children And The Importance Of Their Cognitive And Communicative Development, Maria Elisa Campana

Electronic Theses and Dissertations

This paper will look at the issues of cognitive and communication development in children with Down Syndrome. With recent advances in neuroscience, educators need to understand brain development in order to utilize methods in dealing with education problems that occur with this population. Therefore this paper will look at the Down Syndrome child in both a physiological and educational context, to better understand appropriate methods of intervention. Moreover, brain development and learning involves not only genetic content specific to each individual, but also the many paths laid out by the family, environment, social and educational needs. As they move through …

Placing Birds On A Dynamic Evolutionary Map: Using Digital Tools To Update The Evolutionary Metaphor Of The "Tree Of Life", Sonia Stephens

Electronic Theses and Dissertations

This dissertation describes and presents a new type of interactive visualization for communicating about evolutionary biology, the dynamic evolutionary map. This web-based tool utilizes a novel map-based metaphor to visualize evolution, rather than the traditional "tree of life." The dissertation begins with an analysis of the conceptual affordances of the traditional tree of life as the dominant metaphor for evolution. Next, theories from digital media, visualization, and cognitive science research are synthesized to support the assertion that digital media tools can extend the types of visual metaphors we use in science communication in order to overcome conceptual limitations of traditional …

The Applicability Of Video Self-Modeling For Adults With Developmental And Intellectual Disabilities, Lauren Elizabeth Cox

Electronic Theses and Dissertations

Video Self-Modeling (VSM) has shown to be an effective intervention in modifying maladaptive behaviors in children, particularly those with Intellectual and/or Developmental Disabilities (ID/DD). Although the effectiveness of VSM with children with ID/DD has been well established in the extant literature, considerably fewer studies have addressed the applicability of VSM with adults of the same population. Thus, the goal of the current study was to examine the utility of VSM with three adults with ID/DD, specifically targeting table manners as the behavior of interest for the intervention. Two aspects of table manners were measured utilizing a multiple baseline design: food …

Functional Morphology Of The Sphyrnid Shark Cephalofoil: An Assessment Of The Hydrodynamic Lift Hypothesis Using Computational Fluid Dynamics, Matthew K. Gaylord

Electronic Theses and Dissertations

The hammerhead sharks (Family: Sphyrnidae) are all characterized by a conspicuous lateral expansion and dorsoventral flattening of the head forming a structure known as a cephalofoil, however, there is substantial morphological variation within the clade. Many theories have been proposed regarding the functional aspects of this structure. One of these is that it may produce beneficial dynamic lift as the shark swims (in similar fashion to the cambered wings found on many modern-day aircraft). As sharks do not possess a swim bladder, part of their energy intake is expended on simply maintaining vertical station in the water column. If indeed …

Selection Criteria For Identifying Gifted And Talented Minority Students In Grades One Through Five In Central Mississippi, Tracey Bell

The study consisted of 12 students who were screened using the traditional method of testing and 53 students who were screened using the alternative method of testing. This study attempted to explore strengths and weaknesses in the current system's minority gifted identification process. The alternate screening process did not demonstrate the …

School Psychologist Perceptions Regarding Implementation Of Response To Intervention With English Language Learners, Olivia E. Puyana

Electronic Theses and Dissertations

This research was an investigation of three domains identified through a thorough review of the literature as fundamental to the equitable implementation of Response to Intervention (RtI) with English language learners (ELLs): (1) degree of intercultural sensitivity of educators involved in the RtI process, (2) training of educators in implementation of RtI with ELLs, and (3) educator familiarity with empirically-based interventions for use with ELLs. The validity of using RtI with ELLs has been questioned by both supporters and detractors of the model (Linan-Thompson & Ortiz, 2009). The most fundamental tenets of RtI are predicated upon the use of empirically …

Maya Use And Prevalence Of The Atlatl: Projectile Point Classification Function Analysis From Chichen Itza, Tikal, And Caracol, Andrew J. Ciofalo

Electronic Theses and Dissertations

Multiple scholars have briefly discussed the Maya use of the atlatl. Yet, there has never been a decisive encompassing discussion of prevalence and use of the atlatl in the Maya region with multiple lines of support from iconographic and artifactual analyses. This thesis explores the atlatl at Chichén Itzá, Tikal, and Caracol Maya sites to prove that atlatl prevalence can be interpreted primarily based on projectile point “classification function” analysis with support from iconographic and artifactual remains. The classification functions are derived from creating mutually exclusive groups of dart points and arrow points by using discrete functional analysis. Discerning between …

Metaphoric Competence As A Means To Meta-Cognitive Awareness In First-Year Composition, David T. Dadurka

Electronic Theses and Dissertations

A growing body of writing research suggests college students’ and teachers’ conceptualizations of writing play an important role in learning to write and making the transition from secondary to post-secondary academic composition. First-year college writers are not blank slates; rather, they bring many assumptions and beliefs about academic writing to the first-year writing classroom from exposure to a wide range of literate practices throughout their lives. Metaphor acts as a way for scholars to trace students’ as well as their instructors’ assumptions and beliefs about writing. In this study, I contend that metaphor is a pathway to meta-cognitive awareness, mindfulness, …

The Foods And Crops Of The Muisca: A Dietary Reconstruction Of The Intermediate Chiefdoms Of Bogota (Bacata) And Tunja (Hunza), Colombia, Jorge Luis Garcia

Electronic Theses and Dissertations

The Muisca people of the Eastern Cordillera of Colombia had an exceptionally complex diet, which is the result of specific subsistence strategies, environmental advantages, and social restrictions. The distinct varieties of microclimates, caused by the sharp elevations in this part of the Andes, allows for a great biodiversity of plants and animals that was accessible to the native population. The crops of domesticated and adopted plants of the Muisca include a wide variety of tubers, cereals, fruits, and leaves that are described in detail in this thesis. The Muisca used an agricultural method known as microverticality where the different thermic …

Educating Gifted Students With Asperger's Syndrome: A Case Study Of Three Students And Their Classroom Experiences, Beverly S. Horn

Electronic Theses and Dissertations

Much research has focused on students with Asperger’s Syndrome (AS), and much research has also been done on gifted students with special needs, yet very little has been published that looks at the characteristics of students who have been identified as both Gifted and as having Asperger Syndrome (G/AS), and what teachers are doing in the classroom to meet their needs. This is an important topic because this group of twice exceptional students has characteristics of both exceptionalities, and trying to meet the special needs of both groups in the same classroom would likely be a challenge for the teacher. …

Deconstructing Disability, Assistive Technology: Secondary Orality, The Path To Universal Access, Tara Prakash Tripathi

Electronic Theses and Dissertations

When Thomas Edison applied for a patent for his phonograph, he listed the talking books for the blind as one of the benefits of his invention. Edison was correct in his claim about talking books or audio books. Audio books have immensely helped the blind to achieve their academic and professional goals. Blind and visually impaired people have also been using audio books for pleasure reading. But several studies have demonstrated the benefits of audio books for people who are not defined as disabled. Many nondisabled people listen to audio books and take advantage of speech based technology, such as …

Affirmative Action In Higher Education And The Talented Twenty Program In Florida, Miguel Ubiles

Electronic Theses and Dissertations

Affirmative action in higher education is a necessary component for ethnic minorities to be afforded postsecondary educational access and opportunities to improve their socioeconomic status. The ban of affirmative action in undergraduate admissions, wherever instituted, has decreased the undergraduate enrollment of ethnic minorities. The broad objective of this research is to demonstrate how the elimination of affirmative action has lessened postsecondary educational access for minorities, who presently account for the majority or near-majority population in several states and will soon account for a much larger segment of the national population. This study will use two series of multiple regression models …

Electronic Theses and Dissertations

The purpose of this study was to investigate the extent to which the performance of Title I third grade students in a central Florida School District differed on tests administered under timed and untimed conditions. Further examined was the literature on reasons for the achievement gap which centered around seven different themes: (a) standardized testing, (b) achievement gap data and identified factors (c) deficit theory, (d) cultural mismatch theory, (e) extended time accommodations, (f) test anxiety and stress, and (g) timed versus untimed tests. Six Title I schools participated in this study by assigning 194 students to take the 2006 …

Examination Of An Online College Mathematics Course: Correlation Between Learning Styles And Student Achievement, Bridget Steele

Electronic Theses and Dissertations

The purpose of this study was to determine if there was a significant relationship between learning styles and student learning outcomes in an online college mathematics course. Specifically, the study was guided by two research questions focused on (a) the extent to which learning styles had a predictive relationship with student achievement in an online college mathematics course and (b) the extent to which various learning styles among mathematics students in online versus face-to-face courses predicted mathematics achievement. The population for this study consisted of the 779 college mathematics and algebra (CMA) students who were enrolled in a private multimedia …

The Utility Of Verbal Display Redundancy In Managing Pilot's Cognitive Load During Controller-Pilot Voice Communications, Daniela Kratchounova

Electronic Theses and Dissertations

Miscommunication between controllers and pilots, potentially resulting from a high pilot cognitive load, has been a causal or contributing factor in a large number of aviation accidents. In this context, failure to communicate can be attributed, among other factors, to an inadequate human-system interface design, the related high cognitive load imposed on the pilot, and poor performance reflected by a higher error rate. To date, voice radio remains in service without any means for managing pilot cognitive load by design (as opposed to training or procedures). Such an oversight is what prompted this dissertation. The goals of this study were …
