Purpose: The purpose of this study was to develop and pilot a novel treatment framework called "BEARS" (Balancing Effort, Accuracy, and Response Speed). People with aphasia (PWA) have been shown to maladaptively balance speed and accuracy during language tasks. BEARS is designed to train PWA to balance speed-accuracy trade-offs and…

In an intelligent tutoring system (ITS), it can be useful to know when a student has disengaged from a task and might benefit from a particular intervention. However, predicting disengagement on a trial-by-trial basis is a challenging problem, particularly in complex cognitive domains. In the present work, data-driven methods were used to address…

This dissertation tests a grammatical structure, differential object marking (DOM), which is particularly difficult for L2 learners to acquire. DOM is a phenomenon in which some direct objects are morphologically marked to distinguish them from subjects (Comrie, 1979). In Spanish, animate and specific direct objects are marked with the preposition…

Learning to spell on the computer may lead to functionally useful writing skills. Alan and Suzy, teenagers with developmental disabilities, were already proficient on a variety of naming and matching tasks but had difficulties spelling; Suzy also made errors reading orally. In Experiment 1, computer teaching led to new anagram and written spelling…

Proposes a schematic multidisciplinary model to help developers of intelligent computer-assisted instruction (ICAI) identify the types of required expertise and integrate them into a system. Highlights include domain types and expertise; knowledge acquisition; task analysis; knowledge representation; student modeling; diagnosis of learning needs;…

Discusses self-regulation, learning to learn, and adaptive problem solving, and describes study of third, fifth, and eighth graders. The study investigated whether providing a model of self-regulating skills via teaching a computer to solve problems would increase the number tasks completed, and decrease the error and trial rate. (11 references)…

Instructor diagnosis of pilot trainee errors was studied in the context of instrument flying using a computer simulation system called ORLY. ORLY was used to record student pilot runs on a number of instrument flying tasks. These runs were subsequently replayed to instructor pilots who diagnosed student errors and hypothesized the underlying…

Misuse of English conjunction related to incoherent writing, according to the literature, comes from learners' first language interference, improper mechanical exercises, and misleading lists of connectors in textbooks demonstrated as if mutually interchangeable without contextual constraints. Form-focused instruction with explicit semantic,…
