In this study we investigate students' ability to discern conceptual variation and the use of multiple models in genetics when reading content-specific excerpts from biology textbooks. Using the history and philosophy of science as our reference, we were able to develop a research instrument allowing students themselves to investigate the…

Variations in dosage, content, and family engagement with Early Head Start (EHS) home visiting services were examined for families participating in the EHS Research and Evaluation Project. Families were grouped by characteristics of maternal age, maternal ethnicity, and level of family risk. All home visiting variables were related differentially…

This study examines the simultaneous use of English and Chinese by speakers of Chinese as a heritage language (CHL). It focuses on spontaneous, dynamic, and high-density mixing of the two languages within the smallest building block of a speaking turn: the turn constructional unit (TCU). Drawing upon data from different age and proficiency groups,…

Background: In separate studies and research from different perspectives, five factors are found to be among those related to higher quality outcomes of student learning (academic achievement). Those factors are higher self-efficacy, deeper approaches to learning, higher quality teaching, students' perceptions that their workload is appropriate,…

Background: Recent models of the early emergence of autism spectrum disorder (ASD) propose that infant intrinsic risk susceptibilities in behaviour may be amplified by interaction within the early social environment into an increasingly atypical developmental trajectory. This study examines whether 6- and 12-month parent-infant interactions in…

The Virtual Chemical Vapor Deposition (CVD) Process Development Project provides the context for the two areas of the research presented in this dissertation. The first area, generally referred to as feedback in this dissertation, focuses on student learning and the interactions of students and instructors that take place in the project,…

This study examined associations between Asian international students' perceived quality of contact with faculty, administrative personnel and other students, and self-reported gains in areas identified in "College Students Experience Questionnaire."

Schizophrenia as mental illness is defined in terms of diagnostic criteria which do not include the full range of psychosocial difficulties that shape the lived experience of persons with this diagnosis and affect their quality of life. The biopsychosocial approach found in the World Health Organization's International Classification of…

Learning Chinese characters is a difficult task for adult English native speakers due to the significant differences between the Chinese and English writing system. The visuospatial properties of Chinese characters have inspired the development of instructional methods using both verbal and visual information based on the Dual Coding Theory. This…

This paper outlines a simple and effective model that can be used to evaluate and design educational digital games. It also facilitates the formulation of strategies for using existing games in learning contexts. The model categorizes game goals and learning objectives into one or more of four possible categories. An overview of the model is…

Policy agencies are implementing strategies to increase the use of research in policy decisions. This paper examines the evidence about the effectiveness of these strategies. We conducted an extensive search focused on population health policy and programmes. We classified 106 papers meeting study criteria into research type (conceptual,…

"Incomplete: How Middle Class Schools Aren't Making the Grade" is a new report from Third Way, a Washington, D.C.-based policy think tank. The report aims to convince parents, taxpayers and policymakers that they should be as concerned about middle-class schools not making the grade as they are about the failures of the nation's large, poor, urban…

This document covers the data terms used in the "Australian Vocational Education and Training Statistics: Apprentices and Trainees--Early Trend Estimates December 2010" publication.

The purpose of this quasi-experimental study was to examine attitude and achievement among fifth grade students participating in inquiry and lecture-based forms of instruction through interactive television. Participants (N = 260) were drawn from registered users of NASA's Digital Learning Network[TM]. The first three levels of Bloom's Revised…

Current scholarly understanding of information security regulation in the United States is limited. Several competing mechanisms exist, many of which are untested in the courts and before state regulators, and new mechanisms are being proposed on a regular basis. Perhaps of even greater concern, the pace at which technology and threats change far…
