Performance Assessment For Quality Teaching: Three Critical Variables For Measuring And Improving Teaching And Learning, Kathleen L. Gallagher Phd

Dissertations

While outstanding teachers are any school system's most important investment, assessing the quality of instructional practice has proven to be an ongoing challenge for the profession. Despite assertions that effective teachers are the single most important school-related factor responsible for increased learning, no teacher's employment is dependent on their performance in the classroom or the quality of instruction that they provide. This problem has fueled a growing mistrust in school districts nationwide, specifically in the area of teacher evaluation. One possible explanation is that the profession lacks the scaled level of expertise needed to evaluate instruction consistently and in a …

Accounting For The Attrition Of African American Males In An Academic Support Setting, Ronald R. Lancia Phd

Dissertations

This dissertation addresses a continuing crisis in our nation's education system. Historically African American students have underperformed academically. This achievement gap is particularly pronounced for African American males. AVID (Advancement Via Individual Determination), an academic support program for underachieving students, most recently created the African American Male Initiative (AAMI). The AAMI was designed specifically to respond to the needs of black males. Despite its efforts, the AAMI has had a difficult time attracting and retaining black male participants. The purpose of this study was to better understand why African American high school males are not choosing to participate in the …

Exploring The Paradoxical Role And Experience Of Fallback In Developmental Theory, Valerie Townsend Livesay Phd

Dissertations

Constructive-development and stage development theory, which posits that individuals move through different stages or action logics throughout life, has been the foundation for several models of human transformation. The literature on the leading stage theories indicates that research has focused on exploring stages and their behavioral correlates, but little work has been done on how individuals move between stages. Stage theory has primarily been conceived of as a linear and unidirectional transition from one stage to the next, which encompasses earlier stages, however emerging research has revealed that stage transition may be more fluid and bi-directional than originally thought and …

Data-Driven Decision Making: Teachers' Use Of Data In The Classroom, Tammy Wu Moriarty Phd

Dissertations

Data-driven decision making has become an important educational issue in the United States, primarily because of federal and state emphasis on school accountability and achievement. Data use has been highlighted as a key factor in monitoring student progress and informing decision making at various levels of the education system. Federal and state policies require educators to use data to inform decision making and the assumption is that educators already know how to analyze, interpret, and use data to make informed decisions. The purpose of this study was to gain a better understanding of classroom teachers' engagement in data-driven decision making …

Psychometric Properties Of Standardized Patient And Faculty Rater's Evaluations Of Pre-Licensure Nursing Student Competencies, Karen A. Macauley Phd, Dnp, Fnp-Bc, Gnp, Bc

Dissertations

The use of simulation as a teaching modality has been rooted in the military, aviation, space, and engineering for centuries (Bradley, 2006). Clinical simulation allows for training of healthcare providers that might be too costly, risky, or hazardous in the clinical setting (Bradley, 2006). A variety of simulation modalities are used including virtual learning, task trainers, mannequins, and standardized patients (SPs). External demands for improved accountability of clinical performance is requiring nursing educators to reevaluate methods of teaching and how we measure nursing competence (Nehring & Lashley, 2010). Standardized patients have been used in medical school curricula to teach and …

Teacher Perception Of School Culture And School Climate In The Leader In Me Schools And Non Leader In Me Schools, Brian Patrick Barkley

Dissertations

In 1989 Dr. Stephen Covey wrote The Seven Habits of Highly Effective People which revealed seven habits that people should integrate into their lives that would help them on the two levels of relationships. First, it would help people to establish a better relationship personally. Secondly, it would help people to improve their relationships with other people. The book was originally written for adults; later Sean Covey, son of Dr. Covey, wrote a version of The Seven Habits that was geared toward teenagers. But the question of whether these adult lessons can be taught to five year olds was taken …

Teacher Attitudes Of Inclusion And Academic Performance Of Students With Disabilities, Jonathan Earl Sutton

Dissertations

Since the integration of the inclusion model, supported by the IDEA (1997), within public schools, teacher resistance and frustration has risen (Hardy, 1999). The climate of general education teachers’ classrooms furthermore, has not been the same (Liu & Meyer, 2005). Key elements ensuring success of inclusion and the implementation of inclusive education are the views, perspectives, and attitudes of the personnel who have the responsibility for implementing it; the teachers (Shade & Stewart, 2001). Avramidis and Norwich (2002) argued that successful implementation of any inclusive policy or programming is extremely dependent upon the educators being receptive and positive. Hines (2011) …

Synthesis Of Polyhedral Oligomeric Silsesquioxane (Poss) Functionalized Carbon Nanotubes For Improved Dispersion In Polyurethane Films, Xiaonan Kou

Dissertations

Carbon nanotube (CNT) polymer nanocomposites are promising advanced materials. These materials exhibit the advantages of traditional polymeric materials, such as being light weight and easy to process, combined with the potential to exhibit enhanced mechanical, thermal and electrical properties compared to pure polymers. To achieve substantial improvement of composite properties at low CNT loading, uniform dispersion of CNTs in the polymer matrix and strong CNT-polymer interfacial interaction are needed. However, it is difficult to achieve adequate dispersion and interfacial interactions due to the inert nature of CNTs. In this project, polyhedral oligomeric silsequioxane (POSS) will be used as a dispersing …

Nanoparticle Filled Polymeric Systems For Gas Barrier And Flame Retardant Properties, Yingji Wu

Dissertations

Polymer composite gas barrier and fire retardant properties were studied in this investigation. An increase in the gas barrier property was observed by adding silicate nanotubes or clay nanoparticles into polymeric systems. Oxygen permeability, diffusivity, solubility and water vapor permeability were determined for polyimide/silicate nanocomposites with 0 to 9.99% (vol/vol) filler loading. Both oxygen and water vapor permeability for the system gradually decreased when adding increasing amounts of nanofiller up to 4.50% (vol/vol) and increase again after that. The permeability decrease was caused by both the diffusivity and solubility coefficient changes, although diffusivity (the tortuous factor) is the main reason …

Nursing Students' Attitudes Toward Science In The Nursing Curricula, Jill Deanne Maroo

Dissertations

The nursing profession combines the art of caregiving with scientific concepts. Nursing students need to learn science in order to start in a nursing program. However, previous research showed that students left the nursing program, stating it included too much science (Andrew et al., 2008). Research has shown a correlation between students’ attitudes and their performance in a subject (Osborne, Simon, & Collins, 2003). However, little research exists on the overall attitude of nursing students toward science. At the time of my study there existed no large scale quantitative study on my topic. The purpose of my study was to …

Utilizing Polymer Topology In Peptide-Based Block Copolymers: Unique Aqueous Assembly And Responsive Behavior, Jacob Griffin Ray

Dissertations

This document details work in the area of amphiphilic polypeptide-based block copolymers that are able to self-assemble into well-defined nanostructures in aqueous solution. The main focus of this work is to understand the impacts of polymer topology on self-assembly behavior and response to external stimulus, particularly pH. Poly(L-lysine) and poly(L-glutamic acid) are two pH-responsive, hydrophilic polypeptides that possess the unique property of undergoing α-helix to random coil secondary structure transitions with pH, and this responsiveness can lead to global morphology changes such as changes in aggregate size or even morphology transitions. These polypeptides are synthesized via ring opening polymerization of …

Gene Regulatory Network Reconstruction Using Dynamic Bayesian Networks, Haoni Li

Dissertations

High-content technologies such as DNA microarrays can provide a system-scale overview of how genes interact with each other in a network context. Various mathematical methods and computational approaches have been proposed to reconstruct GRNs, including Boolean networks, information theory, differential equations and Bayesian networks. GRN reconstruction faces huge intrinsic challenges on both experimental and theoretical fronts, because the inputs and outputs of the molecular processes are unclear and the underlying principles are unknown or too complex.

In this work, we focused on improving the accuracy and speed of GRN reconstruction with Dynamic Bayesian based method. A commonly used structure-learning algorithm …

Azide containing ampicillin (AMP) was synthesized and subsequently clicked into the alkyne prepared PE and PP surfaces. Compared to non-functionalized PP and PE surfaces, the AMP clicked surfaces exhibited substantially enhanced antimicrobial activity against Staphylococcus aureus bacteria. To expand the biocompatibility of polymeric surface …

View Of Socioscientific Issues Among Educators: The Willingness Of Teachers To Accept Ssi Into The Classroom And The Reason Underlying Those Beliefs, John Carlos Parr

Dissertations

Socioscientific issues (SSI) are potentially controversial topics, which can be examined using a social and a scientific perspective. The inclusion of these topics in elementary and secondary classrooms has caused a number of conflicts over the past century. In the present study, I explore the willingness of teachers to include three SSI: evolution, stem cell research, and global climate change in the science curricula. Participants included 221 educators currently employed in K-12 schools. Teachers have the greatest impact on classroom instruction, regardless of state curricula. I found most educators willing to include the three previously named SSI in the curricula, …

The Impact Of Smaller Learning Communities On 9th Grade Mathematics Student Achievement And Graduation Rates, Keisha Burney Cook

Dissertations

Many problems in public education, ranging from low student achievement to high dropout rates, are being attributed to large schools, especially large high schools. While large high schools may provide more varied curriculums, they are also more impersonal. This can be especially problematic for ninth graders who are making the transition to high school. One solution that has been implemented as part of educational reform is organizing large high schools into small learning communities. The purpose of this study was to determine if the existence of a smaller learning community has an impact on ninth grade students’ achievement in Georgia …

An Affine Invariant Signed-Rank Multivariate Exponentially Weighted Moving Average Control Chart For Process Location Monitoring, Jamil H. Zeinab

Dissertations

Multivariate statistical process control (SPC) charts for detecting possible shifts in mean vectors assume that data observation vectors follow a multivariate normal distribution. This assumption is ideal and seldom met. Nonparametric SPC charts have increasingly become viable alternatives to parametric counterparts in detecting process shifts when the underlying process output distribution is unknown, specifically when the process measurement is multivariate. This study examined a new nonparametric signed-rank multivariate exponentially weighted moving average type (SRMEWMA) control chart for monitoring location parameters. The control chart was based on adapting a multivariate spatial signed-rank test. The test was affine-invariant and the weighted version …

A Novel Methodology For Calculating Large Numbers Of Symmetrical Matrices On A Graphics Processing Unit: Towards Efficient, Real-Time Hyperspectral Image Processing, Denise Renee Runnels

Dissertations

Hyperspectral imagery (HSI) is often processed to identify targets of interest. Many of the quantitative analysis techniques developed for this purpose mathematically manipulate the data to derive information about the target of interest based on local spectral covariance matrices. The calculation of a local spectral covariance matrix for every pixel in a given hyperspectral data scene is so computationally intensive that real-time processing with these algorithms is not feasible with today’s general purpose processing solutions. Specialized solutions are cost prohibitive, inflexible, inaccessible, or not feasible for on-board applications.

Advances in graphics processing unit (GPU) capabilities and programmability offer an opportunity …
