Development And Validation Of The Statistics Assessment Of Graduate Students, Dammika Lakmal Walpitage Dec 2016

Development And Validation Of The Statistics Assessment Of Graduate Students, Dammika Lakmal Walpitage

Doctoral Dissertations

This study developed the Statistics Assessment of Graduate Students (SAGS) instrument, and established its preliminary item characteristics, reliability, and validity evidence. Even though there are limited number of assessments available for measuring different aspects of statistical cognition, these previously available assessments have numerous limitations. The SAGS instrument was developed using Rasch modeling approach to create a new measure of statistical research methodology knowledge of graduate students in education and other behavioral and social sciences. Thirty-five multiple-choice questions were written with stems representing applied research situations and response options distinguishing between appropriate use of various statistical tests or procedures. A focus …


Sketchmate: A Computer-Aided Sketching And Simulation Tool For Teaching Graph Algorithms, Kristy Sue Van Hornweder Aug 2012

Sketchmate: A Computer-Aided Sketching And Simulation Tool For Teaching Graph Algorithms, Kristy Sue Van Hornweder

Doctoral Dissertations

In this dissertation, we developed and tested a sketching, visualization, and simulation tool called Sketchmate for demonstrating graph algorithms commonly taught in undergraduate computer science courses. For this research, we chose to focus on shortest path and network flow algorithms. Two versions of this tool have been implemented: 1) an instructor tool that supports computer-aided manual simulations of algorithms that augment traditional whiteboard presentations, allowing lectures to be more dynamic and interactive, and 2) a student tool that supports computer-aided manual practice of algorithms that enables students to work through homework problems more quickly while providing detailed incremental feedback about …


Quality Assurance In Engineering Education: A Systems Perspective, Mildred Genevieve Louidor Aug 2010

Quality Assurance In Engineering Education: A Systems Perspective, Mildred Genevieve Louidor

Masters Theses

Engineering education reform has been a topic of discussion for the last twenty years. The concern has only intensified in recent years as stakeholders strive to improve quality in engineering education. Today, stakeholders are recognizing that one of the keys to successful engineering education reform is in taking a systems view of higher education. Academic departments within the higher education system are organized around academic disciplines for the purpose of creating, transferring, and applying knowledge in three principal areas: teaching, research and service. This study addresses the need for quality improvement in the engineering higher education system by first completing …


Factors Related To Student Persistence In A New Residential Stem High School: The Case Of The Tennessee Governor’S Academy For Mathematics And Science, Amy Cinci Sullins May 2010

Factors Related To Student Persistence In A New Residential Stem High School: The Case Of The Tennessee Governor’S Academy For Mathematics And Science, Amy Cinci Sullins

Doctoral Dissertations

Public and private sectors are grappling with decreasing numbers of science, technology, engineering, and mathematics (STEM) professionals as the need for them rises. State-supported STEM residential high schools may be the premier conduit to educate and socialize students in order to prepare for STEM college majors and careers. Gaining understanding of how these schools can nurture students academically and affectively so that they successfully matriculate to university STEM settings is valuable; however, minimal research exists related to the affective domain in relationship to retention at state-supported STEM residential schools. This exploratory, mixed methods case study describes factors that contribute to …
