Spatial or temporal data mining tasks are performed in the context of the relevant space, defined by a spatial neighborhood, and the relevant time period, defined by a specific time interval. Furthermore, when mining large spatio-temporal datasets, interesting patterns typically emerge where the dataset is most dynamic. This dissertation is…

This study explores the lived experiences of project leaders adopting and using Web-2.0 social networking collaboration applications for their project leadership activities. The experiences of 20 project leaders in a Fortune 500 aerospace and defense enterprise in the northeastern United States of America were explored using a qualitative…

This paper illustrates how information collected through interviews can develop a richer understanding of the assignment mechanism, which can result in more plausible causal effect estimates from observational studies and provides a roadmap for sensitivity analysis. Focusing on the issue of assignment to algebra in 8th grade, the author shows how…

This study seeks to develop a model of institutional supports necessary for faculty to succeed as funded scholars at 4-year non-doctoral colleges and universities. Research was conducted using secondary data analysis on a pre-existing, cross-sectional database from the 2004 National Study of Postsecondary Faculty. Expectancy theory was used as the…

Social networking tools used in learning provides instructional design with tools for transformative change in education. This study focused on defining the meanings and essences of social networking through the lived common experiences of 7 college students. The problem of the study was a lack of learner voice in understanding the value of social…

This dissertation researched and reported on how technology was used to facilitate and inform reflective teaching practices.

The study, descriptive in nature, was designed to determine the reflective practices of instructors and how…

This dissertation research examined the changes in item RIT calibration that occurred when adding audio to a set of currently calibrated RIT items and then placing these new items as field test items in the modified assessments on the NWEA MAP test platform. The researcher used test results from over 600 students in the Poway School District in…

With the focus of the American Recovery and Reinvestment Act (ARRA) on struggling schools and reauthorization of the Elementary and Secondary Education Act (ESEA) on the horizon, now is the time to have an honest conversation about what people know--and don't know--about school-level trends. To spur this conversation and to help state and local…

Apprentice and trainee data are reported by the State and Territory Training Authorities to NCVER (National Centre for Vocational Education Research) on a quarterly basis, starting at the September quarter of 1994. The set of data submitted that quarter is referred to as Collection 1. The sets of data submitted in subsequent quarters are referred…

The vertical scales of large-scale achievement tests created by using item response theory (IRT) models are mostly based on cluster (or correlated) educational data in which students usually are clustered in certain groups or settings (classrooms or schools). While such application directly violated assumption of independent sample of person in…

The chemistry-based computer video game is a multidisciplinary collaboration between chemistry and computer graphics and technology fields developed to explore the use of video games as a possible learning tool. This innovative approach aims to integrate elements of commercial video game and authentic chemistry context environments into a learning…

In recent years, researchers have become increasingly interested in the notion of spontaneous focus on form (FonF) (i.e., attention to linguistic forms that arise incidentally during meaningful communication). Previous research has indicated that such FonF is beneficial for L2 learning. However, this research has focused mainly on reactive FonF,…

Objective: This review considers the impact of chromosomal studies on the understanding of childhood neuropsychiatric syndromes, highlighting key discoveries, advances in technology, and new challenges faced by clinicians trying to interpret recent findings. Method: We review the literature on the genetics of child psychiatric disorders, including…

This study investigated whether the instruction of visual design principles had an influence on pre-service teachers' perception and analysis (interpretation) of visual materials. In addition, the relationships between pre-service teachers' visual intelligence and their perception and analysis (interpretation) of visual materials were also…
