A growing number of researchers claim that diverse students with potentially diverse literacies are unable to take up the necessary literate practices to be successful in the university and upon leaving they are unable to master these literate practices, specifically the need to address critical thinking, problem-solving, and writing and to…

An examination of research on expertise reveals potential gaps in current conceptualizations. Examinations of expertise often involve problems in ill-structured domains, which require abstract problem solving. Thus, conceptualizations of expertise are characterized by the use of relatively advanced, abstract problem-solving skills. Problems in…

In recent years, the learning of algebra by all students has become a significant national priority (Moses & Cobb, 2001; National Council of Teachers of Mathematics, 2000). Algebra is considered to be a foundational topic in mathematics (Usiskin, 1988) and some have argued that an understanding of algebra is fundamental to success in today's…

Recent trends indicate a significant decline in the number of students graduating from Science, Technology, Engineering and Math (STEM) programs in the US. The under-representation of students of color, females and low income students in STEM programs has also been documented. Design Based Science (DBS) instruction has been suggested to improve…

Badminton is a growing sport with a limited amount of expertise both in players and coaches so attempts are being made to extend the expertise internationally. The purpose of this study is to gain an understanding of coaching expertise in badminton because such an understanding might have implications for a more general understanding of expertise,…

This study aims to explore how collaborative teacher interaction is contingent upon teachers' immediate classroom and school-organizational contexts as well as broader societal and policy environments. Notwithstanding the widely acknowledged connection between teacher collegiality in schools and its beneficial effects, little systematic effort has…

This research study examines the role of digital media, more specifically online forums, in the development of academic literacy and language learning in English as a Second Language (ESL) college writing. Studies in Second Language Acquisition suggest that participation in online forum discussions can potentially foster collaboration,…

This study investigates the relationship between the use of graphing calculators employed as Type II technology and student achievement, as determined by assessing students' problem solving skills associated with the concept of function, at the college algebra and pre-calculus level. In addition, this study explores the integration of graphing…

This study seeks to contribute to our understanding of the problem of effectively encouraging historical thinking by (a) evaluating, and modifying Wineburg's heuristics for historical thinking for applicability to the problem-solving activities historians use at historic sites; (b) establishing the efficacy of a hypermedia-based education program…

Research shows that mental representation such as analogical reasoning is a fundamental cognitive tool for design problem solving (Daugherty & Mentzer, 2008; Hey, Lensey, Agogino, & Wood, 2008; Lewis, 2008). Not much is known, however, about the way students and professional engineers actively generate and change their mental representation when…

In recent years America witnessed a vast migration of Hispanics into the country. Projections from the U.S. Census Bureau (2008) indicate over the next several decades there will be an unprecedented increase in the Latino population. Due to large influxes in prominent geographical locations, many immigrant cultural beliefs have been preserved, as…

Organizing refers to methods of distributing physical and symbolic tasks among multiple agents in order to achieve goals. My dissertation investigates the dynamics of organizing in hybrid information processing systems that incorporate both humans and computers. To explain the behavior of these hybrid systems, I develop and partially test a theory…

Cartesian tensor bases have been widely used to model spherical functions. In medical imaging, tensors of various orders can approximate the diffusivity function at each voxel of a diffusion-weighted MRI data set. This approximation produces tensor-valued datasets that contain information about the underlying local structure of the scanned tissue.…

In recent decades many comparative studies in mathematics have been conducted involving students in China and the United States. There have been claims that U.S. students are more creative than their Chinese counterpart, but Chinese students have better basics in mathematics. Nevertheless, there have been very few comparative studies on creativity…

Originating from the literature on resiliency, adult learning, and professional development, this qualitative study investigated how the relationship between resiliency and adult learning influenced professional development in one suburban-rural school district in Litchfield County, Connecticut. Data represent findings on the perceptions of…
