How do teachers learn about what learners already know? How do learners aid teachers by providing them with information about their background knowledge and what they find confusing? We formalize this collaborative reasoning process using a hierarchical Bayesian model of pedagogy. We then evaluate this model in two online behavioral experiments (N…

This study proposes a Bayesian method for diagnostic classification models (DCMs) for a partially known Q-matrix setting between exploratory and confirmatory DCMs. This Q-matrix setting is practical and useful because test experts have pre-knowledge of the Q-matrix but cannot readily specify it completely. The proposed method employs priors for…

Current literature lacks explication of how traditional grounded theory and mixed methods--grounded theory (MM-GT) are similar/different and specific explication of how to construct MM-GT designs--our purpose is to do this. We illustrate the design process using a published study. Exploratory Phase 1 involves creation of a formative-theoretical…

One of the most widely used communication tools in evaluation is the logic model. Despite its extensive use, there has been little research into the visualization aspect of the logic model. To assess the impact that design modifications would have on its effectiveness, we applied established visualization principles to revise a program model.…

This dissertation describes a qualitative research study that grows our understanding of the career development experiences, supports, and barriers of social entrepreneurs who are gifted adults (SEGA) so that we may nurture the career development of future SEGA. Research questions for this study probed the career development experiences, supports,…

To learn to read, the brain must repurpose neural systems for oral language and visual processing to mediate written language. We begin with a description of computational models for how alphabetic written language is processed. Next, we explain the roles of a dorsal sublexical system in the brain that relates print and speech, a ventral lexical…

Executive functions (EF) are a collection of cognitive domains governing task initiation, motor planning, attention, and goal-oriented action. Difficulties with EF have marked impacts on adaptive living skills, learning outcomes, and quality of life for people with cognitive and psychosocial disabilities, as well as the broader population. While…

This pilot study is a mixed-methods sequential explanatory study that investigated the effects of watching text-relevant video segments supported by the Schematic Information-Processing (SIP) model of reading comprehension on reading comprehension of adult speakers of English as a Second Language (ESL) in terms of text familiarity and the…

This revised edition updates and expands on the first edition published in 2016. In this revised edition, theories of different types of learning strategies are expanded and more recent studies are added. A large amount of tabular information is also reconstructed in a more meaningful manner. The book is divided into five chapters. Chapter one…

We taught 4 participants with autism to discriminate between the reinforced and nonreinforced responses of an adult model and evaluated the effectiveness of this intervention using a multiple baseline design. During baseline, participants were simply exposed to adult models' correct and incorrect responses and the respective consequences of each.…

"The Practice Base for How We Learn: Supporting Students' Social, Emotional, and Academic Development" outlines promising practices that show how students, teachers, parents, and administrators can integrate social, emotional, and academic learning in preK-12 education. The report, which represents the vision of the 34-member Council of…

Adults refer young children's attention to things in two basic ways: through the use of pointing (and other deictic gestures) and words (and other linguistic conventions). In the current studies, we referred young children (2- and 4-year-olds) to things in conflicting ways, that is, by pointing to one object while indicating linguistically (in…

Background: Recent attention to health of people with intellectual disabilities has used a health disparities framework. Building on historical context, the paper summarizes what is known about health disparities from reports and research and provides direction on what to do to reduce these disparities among adults with intellectual disabilities.…

The 10th International Conference on Educational Data Mining (EDM 2017) is held under the auspices of the International Educational Data Mining Society at the Optics Velley Kingdom Plaza Hotel, Wuhan, Hubei Province, in China. This years conference features two invited talks by: Dr. Jie Tang, Associate Professor with the Department of Computer…

Objective: To examine the association between income and the consumption of fruits and vegetables using the poverty income ratio (PIR). Design: Association between PIR and intake of fruits and vegetables combined. The PIR was divided into 5 groups ranging from less than poverty threshold (PT) to greater than or equal to 400% PT. Participants:…
