We investigated whether students increased their self-assessment accuracy and essay scores over the course of an intervention with a writing strategy intelligent tutoring system, W-Pal. Results indicate that students were able to learn from W-Pal, and that the combination of strategy instruction, game-based practice, and holistic essay-based practice led to(More)
Work in cognitive and educational psychology examines a variety of phenomena related to the learning and retrieval of information. Indeed, Alice Healy, our honoree, and her colleagues have conducted a large body of groundbreaking research on this topic. In this article we discuss how 3 learning principles (the generation effect, deliberate practice and(More)
This study builds upon previous work aimed at developing a student model of reading comprehension ability within the intelligent tutoring system, iSTART. Currently, the system evaluates students' self-explanation performance using a local, sentence-level algorithm and does not adapt content based on reading ability. The current study leverages natural(More)
The purpose of this study was to investigate students’ patterns of interactions within a game-based intelligent tutoring system (ITS), and how those interactions varied as a function of individual differences. The analysis presented in this paper comprises a subset (n=40) of a larger study that included 124 high school students. Participants in the current(More)
We investigate how writing proficiency relates to the flexible use of cohesion. Forty-five students wrote 16 essays across 8 sessions. Natural language processing techniques were used to calculate the cohesion of each essay. Random walk and Euclidian distance measures were then used to visualize and classify students’ flexibility in cohesion across the(More)
This study expands upon an existing model of students’ reading comprehension ability within an intelligent tutoring system. The current system evaluates students’ natural language input using a local student model. We examine the potential to expand this model by assessing the linguistic features of self-explanations aggregated across entire passages. We(More)
Within the educational community, research on student literacy often combines reading and writing measures, as they are presumed to draw on similar skills and background knowledge. However, relatively few studies have investigated the underlying cognitive skills required for both activities, and to what extent the required background knowledge and cognitive(More)
