Fundamental to amassing a lexicon of relational terms (i.e., verbs, prepositions) is the ability to abstract and categorize spatial relations such as a figure (e.g., "boy") moving along a path (e.g., "around" the barn). Three studies examine how infants learn to categorize path over changes in "manner," or how an action is performed (e.g., running…

Having good spatial skills strongly predicts achievement and attainment in science, technology, engineering, and mathematics fields (e.g., Shea, Lubinski, & Benbow, 2001; Wai, Lubinski, & Benbow, 2009). Improving spatial skills is therefore of both theoretical and practical importance. To determine whether and to what extent training and…

This study leveraged the complementary nature of confirmatory factor (CFA), item response theory (IRT), and latent class (LCA) analyses to strengthen the rigor and sophistication of evaluation of two new measures of the Air Force Academy's "leader of character" definition--the Character Mosaic Virtues (CMV) and the Leadership Mosaic…

The purpose of this quantitative study was to determine the importance and priority of practices for directors of career and technical education in the state of Indiana. An analysis was prepared to determine the rankings and correlations of importance and priorities of 50 leadership practices as well as 11 categories of practices for the career…

Teachers face new challenges when they teach a more rigorous mathematics curriculum than one to which they are accustomed. The rationale for this particular study originated from watching teachers struggle with understanding mathematical content and pedagogical practices. Mathematics coaches can address teachers' concerns through sustained,…

Research on the topic of cell phones has proliferated over the past decade. Based on a review of the literature, it appears that the majority of the extant research on the topic resides in the technology, education, and social sciences fields. Recent reviews indicate that the scope of the research on cell/mobile phones is eclectic in nature…

This study examined the effectiveness of a new learning approach in teaching classification of invertebrate animals in biology courses. In this approach, we used an impersonal style: the subject jigsaw, which differs from the other jigsaws in that both course topics and student groups are divided. Students in Jigsaw group were divided into five…

Some syllables are louder, longer and stronger than other syllables at the lexical level. These prominent prosodic characteristics of certain syllables are captured by suprasegmental features including fundamental frequency, duration and intensity. A language like English uses fundamental frequency, duration and intensity to distinguish stressed…

The symptoms, assessment, and treatments of Post Traumatic Stress Disorder (PTSD) have been empirically investigated to the extent that there is a breadth of valid and reliable instruments investigating this psychopathological syndrome. There, too, exists a substantial evidence base for various treatment models demonstrating effectiveness in…

A valid screening system requires a screener that accurately predicts whether or not students are at risk given their current performance. To understand a screening measure's accuracy, predicted student performance data (i.e., screening data) must be compared with actual performance data. When these sets of data are compared in a setting where…

This study compares Spanish morphosyntax error types and magnitude in monolingual Spanish and Spanish-English bilingual children with typical language development (TD) and language impairment (LI). Performance across groups was compared using cloze tasks that targeted articles, clitics, subjunctives, and derivational morphemes in 57 children.…

"Nuu Savi" ("Sacred Rain's collectivity"), the Mixtec people of southern Mexico, had created some of the most complex polities in the continent at the time of European contact. Five hundred years later, they remain cohesive, culturally distinct communities, as increasing numbers of individuals and families migrate to northern…

This dissertation examines three topics in the morphosyntax of Lubukusu (Bantu, Kenya), all of which are concerned with agreement with subjects: locative inversion, complementizer agreement, and alternative agreement effects in subject extraction. Each topic reports novel Lubukusu data which are both typologically interesting and theoretically…

This document covers the data terms used in the "Apprentice and Trainee Destinations Survey, 2010" report and its associated data tables. The primary purpose of this document is to assist users of the report to understand the specific data terms used within it. Terms that appear in the report are listed in alphabetical order with the…

Science textbooks have a major influence on teaching and learning. Teachers and instructors at all educational levels use them regularly not only as a guide for course content and sequence but also in the design of homework assignments and assessment probes. From this perspective, textbook questions and problems can be expected to have a strong…
