Comparing Relaxation Versus Mastery Microbreak Activity: A Within-Task Recovery Perspective

Comparing Techniques for Preference Relaxation: A Decision Theory Perspective

This research proposes a decision aid based on a novel type of preference relaxation, which enables consumers to easily make quality choices in online multiattribute choice scenarios. In contrast to filtering and recommendation mechanisms that are a potential solution to this problem, our method combines decision theory with preference relaxation and enables consumers to consider high-quality a...

Pretask versus within-task anxiety measures in predicting performance on a concept acquisition task.

Comparing Multiple Paths to Mastery: What is Learned?

Contemporary theories of learning postulate one or at most a small number of different learning mechanisms. However, people are capable of mastering a given task through qualitatively different learning paths such as learning by instruction and learning by doing. We hypothesize that the knowledge acquired through such alternative paths differs with respect to the level of abstraction and the ba...

The Hospital Data Project: comparing hospital activity within Europe.

BACKGROUND The ability to measure and compare hospital activity between EU member states is important for policy, planning, financing and assessment of population health. Earlier initiatives in this area have been largely directed at standardising high-level indicator definitions without proper account of differences in health systems and health information systems. The Hospital Data Project (H...

Defining Mastery: Knowledge Tracing Versus N- Consecutive Correct Responses

Knowledge tracing (KT) is well known for its ability to predict student knowledge. However, some intelligent tutoring systems use a threshold of consecutive correct responses (N-CCR) to determine student mastery, and therefore individualize the amount of practice provided to students. The present work uses a data set provided by ASSISTments, an intelligent tutoring system, to determine the accu...
