The purpose of this study was to develop a framework for analyzing and evaluating student-constructed models of physical phenomena and monitoring the progress of these models. Moreover, we aimed to examine whether this framework could capture differences between models created using different computer-based modeling tools; namely, computer-based…

With community colleges educating up to one-half of all U.S. undergraduates, more focus on internationalization is warranted in order to ensure student competitiveness in today's global labor pool. This ex post facto study of 2006 survey data from the American Council on Education (ACE) found a low level of internationalization occurring at most…

The present study evaluated the stability of math learning difficulties over a 2-year period and investigated several factors that might influence this stability (categorical vs. continuous change, liberal vs. conservative cut point, broad vs. specific math assessment); the prediction of math performance over time and by performance level was also…

Estimating the difficulty level of math word problems is an important task for many educational applications. Identification of relevant and irrelevant sentences in math word problems is an important step for calculating the difficulty levels of such problems. This paper addresses a novel application of text categorization to identify two types of…

The paper focuses on analysing grade 12 learner errors and the misconceptions in calculus at a secondary school in Limpopo Province, South Africa. As part of the analysis the paper outlines the nature of mathematics errors and misconceptions. Coding of learners' errors was done through the lens of a typological framework. The analysis showed that…

This dissertation examines the relationship between the structural, phonemic properties of vowel inventories and their acoustic phonetic realization, with particular focus on the adequacy of Dispersion Theory, which maintains that inventories are structured so as to maximize perceptual contrast between their component vowels. In order to assess…

The linguistic relativity hypothesis proposes that speakers of different languages perceive and conceptualize the world differently, but do their brains reflect these differences? In English, most nouns do not provide linguistic clues to their categories, whereas most Mandarin Chinese nouns provide explicit category information, either…

This exploratory, qualitative research explored the extent that course syllabi in the Departments of English in 13 public and 9 private universities in Taiwan reflect the inclusion of syllabus components to promote learning as recommended in the literature in the United States. Research questions included: what components can be inferred from the…

Questioning is an essential and generative studying practice for prospective teachers (PTs) as they develop their mathematical content knowledge needed for teaching. This study examines PTs' questioning interactions by describing the types of questions they ask during small group discussions in a required mathematics content course and how their…

English Language Learners (ELLs) are the fastest growing group of students in American public schools. According to Payan and Nettles (2008), the ELL population doubled in 23 states between 1995 and 2005. The U.S. Census Bureau estimates that by 2050, the Hispanic school-age population will exceed the non-Hispanic white school-age public school…

This dissertation seeks to understand the interplay between informal articulations of social categories and formal instantiations of those categories in official language. Specifically, it explores the process of social categorization as it is used to identify threats to national security. The research employed a qualitative, document-based,…

This study determined what levels of thinking were included in Christian publishers' elementary reading textbooks and if there was a statistically significant difference between the levels of thinking in different textbooks. A proportional random sample of reading comprehension questions was drawn from the fifth grade teacher's editions of reading…

The present study investigated longitudinal changes of the reading achievement among schools populated with English learners. It also examined the heterogeneity in the English learners group in terms of students' performance in high stakes reading tests. Historically, English learners have often been considered the students who are in the process…

National communications systems (NCS) are critical elements of a government's infrastructure. Limited improvements to the non-functional requirements (NFR) of NCS have caused issues during national emergencies such as 9/11 and Hurricane Katrina. The literature indicates that these issues result from a deficiency in understanding the roles NFRs and…
