A Correlational Study Of Telework Frequency, Information Communication Technology, And Job Satisfaction Of Home-Based Teleworkers, Shana P. Webster-Trotman Jan 2010

A Correlational Study Of Telework Frequency, Information Communication Technology, And Job Satisfaction Of Home-Based Teleworkers, Shana P. Webster-Trotman

Walden Dissertations and Doctoral Studies

In 2008, 33.7 million Americans teleworked from home. The Telework Enhancement Act (S. 707) and the Telework Improvements Act (H.R. 1722) of 2009 were designed to increase the number of teleworkers. The research problem addressed was the lack of understanding of factors that influence home-based teleworkers' job satisfaction. Job dissatisfaction has been found to have a significant impact on voluntary turnover. The purpose of the study was to assess the relationship among telework frequency, information communication technology (ICT), and job satisfaction. The research questions were designed to answer whether correlational relationships exist among telework frequency, ICT, and job satisfaction and …


Assimilative Domain Proficiency And Performance In Chemistry Coursework, Scott William Byrnes Jan 2010

Assimilative Domain Proficiency And Performance In Chemistry Coursework, Scott William Byrnes

Walden Dissertations and Doctoral Studies

The assimilation and synthesis of knowledge is essential for students to be successful in chemistry, yet not all students synthesize knowledge as intended. The study used the Learning Preference Checklist to classify students into one of three learning modalities -- visual, auditory, or kinesthetic (VAK). It also used the Kolb Learning Style Inventory (KLSI), which utilizes four learning domains - Converging, Accommodating, Diverging, and Assimilating - to explain the students' maturation process by showing shift from any domain towards the Assimilating domain. A shift approaching this domain was considered as improvement in the assimilation and synthesis of knowledge. This pre-experimental …


The Effect Of Learning Styles Strategies On Benchmark Eighth Grade Middle School Mathematics Achievement, Jean Ferrara Jan 2010

The Effect Of Learning Styles Strategies On Benchmark Eighth Grade Middle School Mathematics Achievement, Jean Ferrara

Walden Dissertations and Doctoral Studies

Low standardized mathematics scores resulted in a suburban middle school not reaching adequate yearly progress (AYP) for the 2 previous years. There were many possible factors contributing to this problem, among them the design of instruction. The purpose of this study was to identify learning styles of students and implement differentiated instructional strategies that address the learners' needs. The study was based on the Silver and Hanson's theory of learning style instruction and Gardner's multiple intelligences as a model for differentiating instruction. This sequential mixed methods quasi-experimental causal comparative design study investigated the effect of classroom intervention based on learning …


Investigating An Optimal Decision Point For Probability Bounds Analysis Models When Used To Estimate Remedial Soil Volumes Under Uncertainty At Hazardous Waste Sites, Charles O. Dankwah Jan 2010

Investigating An Optimal Decision Point For Probability Bounds Analysis Models When Used To Estimate Remedial Soil Volumes Under Uncertainty At Hazardous Waste Sites, Charles O. Dankwah

Walden Dissertations and Doctoral Studies

Hazardous waste site remediation cost estimation requires a good estimate of the contaminated soil volume. The United States Environmental Protection Agency (U.S. EPA) currently uses deterministic point values to estimate soil volumes but the literature suggests that probability bounds analysis (PBA) is the more accurate method to make estimates under uncertainty. The underlying statistical theory is that they are more accurate than deterministic estimates because probabilistic estimates account for data uncertainties. However, the literature does not address the problem of selecting an optimal decision point from the interval-valued PBA estimates. The purpose of this study was to identify the optimal …


Comparing The Effects Of Two Asynchronous Teaching Methods, Wikis And Eboards, On Spanish Students' Cultural Proficiency, Kristopher D. Muir Jan 2010

Comparing The Effects Of Two Asynchronous Teaching Methods, Wikis And Eboards, On Spanish Students' Cultural Proficiency, Kristopher D. Muir

Walden Dissertations and Doctoral Studies

Culture tends to be misplaced as a secondary instructional goal in most foreign language classrooms. Although research has suggested that a strong link exists between language and culture, the problem resides in how best to teach culture in the classroom. While this problem impacts all learners, it may affect high school students more because they are entering a multilingual and multicultural world through higher education, study abroad, and employment. Based on Moran's conceptual framework of culture, this study addressed a gap in the literature by examining the effects of 2 innovative technologies, wikis and eBoards, and their potential to improve …


The Use Of Human Patient Simulators To Enhance The Clinical Decision Making Of Nursing Students, Sharon Kay Powell-Laney Jan 2010

The Use Of Human Patient Simulators To Enhance The Clinical Decision Making Of Nursing Students, Sharon Kay Powell-Laney

Walden Dissertations and Doctoral Studies

One of the newest teaching modalities in nursing education is the use of human patient simulators (HPS). An HPS simulation scenario creates a software program vignette in which students interact with a manikin to practice caring for critical patients in a risk-free environment. Although used extensively in schools of nursing, there is little research that examines if these expensive simulators improve the clinical decision-making ability of nursing students. The purpose of this experimental differentiated treatment study was to assess if HPS technology leads to increased clinical decision-making ability and clinical performance more than the teaching modality of a paper and …


A Structural Equation Model Of The Factors Associated With Influence And Power Of It Departments And Their Relationship To Firm's It Orientation And Business Performance, Raghu V. Kowshik Jan 2010

A Structural Equation Model Of The Factors Associated With Influence And Power Of It Departments And Their Relationship To Firm's It Orientation And Business Performance, Raghu V. Kowshik

Walden Dissertations and Doctoral Studies

Although few firms can function without an information technology (IT) department, senior executives often consider IT as secondary. Historically, studies have found IT departments to have low influence and power status compared to other departments. Few, if any, studies have investigated what factors contribute to this subservient position. Three research questions that inspired this study regarding the IT department's influence and power included factors that shape the IT influence and power, the consequences for the firm's IT orientation and business performance, and how firm's IT orientation affects business performance. This quantitative study explored the notion that accountability, innovativeness, customer connectedness …
