Accepting that learning is dialogic necessitates the development of teaching and learning activities that support a learning-conversation. Further, Blended Learning requires learning technologies to support the conventional teaching settings by constructing activities that enhance, rather than simply replace, the conventional teaching settings. Just-in-Time Teaching is one such strategy that ac...

Although our Readers, as well as ourselves, have just cause to be tired of the subject of this volume; yet while fever continues to ravage on the vitals of the community, arid men of experience to lay before their brethren the results of their observations, it is the duty of the Journalist to pourtray, and of the Reader to patiently audit, these records of passing events, in which all are more ...

Adaptive course generation becomes more appropriate for realistic usage scenarios and more flexible if it includes mechanisms deciding just-in-time which content, which exercises, which external resources, and which tools to include for an individual student. We developed such a just-in-time delivery framework (called Dynamic Items) that is used for enhancing the adaptivity of (educational) onl...

Semantically rich domains require operative knowledge to solve complex problems in real-world settings. These domains provide an ideal environment for developing authentic constructivist e-learning environments. In this paper we present a framework and a methodology for developing authentic learning environments for such domains. The framework is based on an ecological view and characterizes di...

Titan Healthcare was founded in 1975 by a group of doctors who wanted to do healthcare differently. They realized that the Fee-ForService model of providing healthcare was inefficient and didn’t accurately address the total healthcare needs of the patient. Rather, it increased the costs by encouraging doctors to perform more services than necessary, and to not pay close attention preventative m...

For scatterplots with gaussian distributions of dots, the perception of Pearson correlation r can be described by two simple laws: a linear one for discrimination, and a logarithmic one for perceived magnitude (Rensink & Baldridge, 2010). The underlying perceptual mechanisms, however, remain poorly understood. To cast light on these, four different distributions of datapoints were examined. The...
