Sociotechnical Systems Approach For Designing Effective Pre-College Stem Programs For Adult Students, Ifeoma Okechukwu
Sociotechnical Systems Approach For Designing Effective Pre-College Stem Programs For Adult Students, Ifeoma Okechukwu
Wayne State University Dissertations
In the context of its external environment, sociotechnical systems (STS) are tools for restructuring an organization’s components into inter-related and interdependent social and technical subsystems for improving the organization’s performance and the well-being of its actors. The theory of STS states that the optimal performance and effectiveness of an organization lies in the joint optimization of the social (all human-based elements) and the technical (the tools and technology for doing work) subsystems. Many technical industries know the benefits of STS, however the concept has a minimal presence in education, in spite of education’s many challenges such as improving the graduation …
Teachers' Reflection On Their Beliefs And Question-Asking Practices During Mathematics Instruction, Kaili Takiyah Hardamon
Teachers' Reflection On Their Beliefs And Question-Asking Practices During Mathematics Instruction, Kaili Takiyah Hardamon
Wayne State University Dissertations
Teachers’ daily instructional practices are a critical component in creating a rich and meaningful educational experience for students. Thus, factors that inform instructional practices are of particular importance and interest to education researchers and other stakeholders. Beliefs about teaching and learning are a known factor influencing teachers’ instructional practices (Ernest, 1989). This study focused on a specific instructional practice, question-asking, which has a profound impact on students’ experience with mathematics (Weiland, Hudson, and Amador (2014). Understanding the relationship between teachers’ beliefs and practice helps to make sense of teachers’ decision-making processes, particularly as they choose questions to ask students during …
A Comparative Study Of Kendall-Theil Sen, Siegel Vs Quantile Regression With Outliers, Ahmad Farooqi
A Comparative Study Of Kendall-Theil Sen, Siegel Vs Quantile Regression With Outliers, Ahmad Farooqi
Wayne State University Dissertations
Researchers in social and behavioral sciences usually interested in study the relationship between a response variable Y_i and one or more independent predictors〖 X〗_i either for the purpose of explanation or prediction. Ordinary Least Square Regression is a parametric approach used to study this kind of relationship. One of the disadvantages of Ordinary Least Square is it does not fit well in the presence of outliers in the response variable Y_i or both in the response variable Y_i and the predictor variable〖 X〗_i, also if the data were sampled from a non-normal distribution. Quantile Regression, Theil-Sen regression, and the modified …

The Relation Between Patient Education And Picc Line Occlusion, Patricia Louise Petroulias
Wayne State University Dissertations
The purpose of this study was to test the feasibility of using an electronic tablet to supplement patient and caregiver education about PICC line maintenance and to compare the percentage of PICC line complications in the intervention group with national percentage rates for patients and caregivers. Newly diagnosed cancer patients who had PICC lines inserted participated in this study. They used an electronic tablet to learn the 10 steps for flushing their PICC lines correctly. They also met with the researcher via FaceTime to review the steps.
A total of 11 patients participated in this quasi-experimental pilot study. They completed …
Networks Of Users And Powers: Blackboard Software Roadmap As Cultural Practice, Diana Gellci
Networks Of Users And Powers: Blackboard Software Roadmap As Cultural Practice, Diana Gellci
Wayne State University Dissertations
With the rapid growth of eLearning applications - the software providing for learning through the Internet - it has become commonplace to describe those technologies as both simple tools and user-friendly. These two vague yet suggestive terms make the operating of the technology appear as social value and any related issues as a user's problem. Interested neo-liberal groups take a step further when considering eLearning technologies as the solution for the problems faced in the field. STS studies recognize that technology fetishism is strategically employed to justify the latest developments of capitalism as technological and logical.
This doctoral study examines …
Using Large-Angle Beamstrahlung To Detect And Diagnose Colliding Beams For Luminosity Optimization, Hussein Farhat
Using Large-Angle Beamstrahlung To Detect And Diagnose Colliding Beams For Luminosity Optimization, Hussein Farhat
Wayne State University Dissertations
The large-angle-beamstrahlung is a very effective technique that can be used to monitor two crossing beams. Monitoring the beam helps in analyzing and studying the beams profiles, allowing beams adjustments, and eventually leading to a perfect beams collision. The perfect beam collision results in a higher luminosity; as a result, a high particles production rate and new physics can be discovered.
The Impact Of Nested Testing On Experiment-Wise Type I Error Rate, Jack Sawilowsky
The Impact Of Nested Testing On Experiment-Wise Type I Error Rate, Jack Sawilowsky
Wayne State University Dissertations
When conducting a statistical test the initial risk that must be considered is a Type I error, also known as a false positive. The Type I error rate is set by nominal alpha, assuming all underlying conditions of the statistic are met. Experiment-wise Type I error inflation occurs when multiple tests are conducted overall for a single experiment. There is a growing trend in the social and behavioral sciences utilizing nested designs. A Monte Carlo study was conducted using a two layer design. Five theoretical distributions and four real datasets taken from Micceri (1989) were used, each with five different …

Advisor: Dr. Shlomo Sawilowsky
Major: Educational Evaluation and Research
Degree: Doctor of Philosophy
Micceri (1989) examined the distributional characteristics of 440 large-sample achievement and psychometric measures. All the distributions were found to be nonnormal at alpha = .01. Micceri indicated three factors that might contribute to a non-Gaussian error distribution in the population. The first factor is subpopulations within a target population. The second factor is ceiling effects and the third factor is treatment effects that may change the location parameter, variability, or shape of the …

Competencies Of Expert Web-Based Instruction Designers, Yonghui Chen
Wayne State University Dissertations
Web-based instruction has been increasingly accepted in education, business and industry, military and government, healthcare and other sectors as a dominant means to deliver instruction beyond time and geographical constraints. However, the overall quality of WBI courses or programs remains a concern. The reasons for the ineffectiveness can be many, of which is the lack of sufficient competencies and skills in existing professionals. This study attempts to identify the domains, competencies, performance statement for instructional designers in WBI at the expert level. IBSTPI competency model has been used as the conceptual framework, utilizing mixed methods.
As a result, 91 performance …
The Dependent Samples T And Wilcoxon Sign Rank Maximum Test, Saverpierre Maggio
The Dependent Samples T And Wilcoxon Sign Rank Maximum Test, Saverpierre Maggio
Wayne State University Dissertations
A maximum test using the parametric dependent samples t-test and the non-parametric Wilcoxon sign rank test was created using a FORTRAN program and various subroutines of the International Mathematical and Statistical Libraries (IMSL, 1980). Two tailed critical values were derived from a mixed normal distribution. Critical values obtained were at the 0.05, 0.025, 0.01 and 0.005 alpha levels via sample sizes (n) 8 through 30, 45, 60, 90 and 120. Critical values were compared to values obtained through the application of the Bonferroni correction method. It was concluded that the Bonferroni is an unnecessary method. Findings of the study are …

This study is based on a qualitative multiple case study research design using a mixed methods approach to provide insight into the effect of interactive technology on informal learning and performance in a social business setting inhabited by knowledge workers. The central phenomenon examined is the variance in behavioral intention towards interactive Web 2.0 technologies in learning and performance-related activities, depending on social and cultural setting, observable in individual and group usage patterns.
The theoretical foundation for this study is drawn primarily from the activity theory model developed by Engeström (1987) and related research enabled by an ongoing review of …
A Comparison Of The Effects Of Non-Normal Distributions On Tests Of Equivalence, Linda Ellington
A Comparison Of The Effects Of Non-Normal Distributions On Tests Of Equivalence, Linda Ellington
Wayne State University Dissertations
Statistical theory and its application provide the foundation to modern systematic inquiry in the behavioral, physical and social sciences disciplines (Fisher, 1958; Wilcox, 1996). It provides the tools for scholars and researchers to operationalize constructs, describe populations, and measure and interpret the relations between populations and variables (Weinbach & Grinnell, 1997; Wilcox, 1996). Given that the majority of real data analysis in the behavioral and social sciences is comprised of non-normally distributed data, it is important that researchers be aware of the effects of non-normal distributions on the probability of detecting equivalence between populations.
The present study examined the effects …
Approximate Vs. Monte Carlo Critical Values For The Winsorized T-Test, Michael Lance
Approximate Vs. Monte Carlo Critical Values For The Winsorized T-Test, Michael Lance
Wayne State University Dissertations
Historically, it has been accepted practice for critical values for the Winsorized t test for independent samples to be based on adjusted degrees of freedom depending on the number of total non-Winsorized (approximate) values. Recently, a new such table of Winsorized critical values has been developed via approximate randomization by Monte Carlo simulation.
Based on eight common data distributions estimated from Psychology and Education along with the normal and five Mathematical distributions, these two tables of values were compared with respect to robustness to types I and II errors through Monte Carlo simulations for one and 10% Winsorized values per …
