This paper evaluates dialogue-based student performance in a controlled experiment using versions of a tutoring system with and without automatic adaptation to the student affective state of uncertainty. Our performance metrics include correctness, uncertainty, and learning impasse severities, which are measured in a “test” dialogue after the tutoring treatment. Although these metrics did not s...

The value of experiential learning in agricultural education has long been recognized as an important part of the educational process. Through practice and experience students apply what they have learned in real situations, thus the material becomes understandable and usable. Moreover, in the process of gaining experience, new problems and situations arise causing learners to seek additional i...

Background—The Iowa Department of Education undertook a study to determine district characteristics that are associated with success on statewide-standardized tests. A district profile was created for each Iowa public school district to determine if any association exists between a particular district’s characteristics and the test scores of 11th grade students. Contextual variables such as soc...

BACKGROUND The number of medical undergraduates taking part in Student Scientific Activities (SSA) at Jessenius Faculty of Medicine Comenius University in Slovakia remains low. The aim of this study was to discover some of the factors responsible and suggest improvements. METHODS An anonymous 30-item questionnaire was devised and sent to 245 medical undergraduates (UG) of the 1st, 2nd, 3rd an...

Although the rise in subprime lending and the ensuing wave of foreclosures was partly a result of market forces that have been well-identified in the literature, in the United States it was also a highly racialized process. We argue that residential segregation created a unique niche of poor minority clients who were differentially marketed risky subprime loans that were in great demand for use...

BACKGROUND Observation of the performance of medical students in the clinical environment is a key part of assessment and learning. To date, few authors have examined written comments provided to students and considered what aspects of observed performance they represent. The aim of this study was to examine the quantity and quality of written comments provided to medical students by different ...

Past studies have shown that Bayesian Knowledge Tracing (BKT) can predict student performance and implement Cognitive Mastery successfully. Standard BKT individualizes parameter estimates for skills, also referred to as knowledge components (KCs), but not for students. Studies deriving individual student parameters from the data logs of student tutor performance have shown improvements to the s...
