This article describes the development of learning widget on m-learning and e-learning environments. A widget is a small, simple and useful application supporting user-oriented contents. The user may select and install widgets that are convenient as well as an auto-updating application including weather or calendar. These widgets are especially…

In this paper, we present a data-based user modeling framework that uses both unsupervised and supervised classification to build student models for exploratory learning environments. We apply the framework to build student models for two different learning environments and using two different data sources (logged interface and eye-tracking data).…

This report discusses research commissioned by the Corporation for Public Broadcasting in order to evaluate prototypes of digital public television programming. There were two phases of research, the first using exclusively linear demonstrations of interactive public television, and the second demonstrating computer simulations of three digital…

Describes a new model for quantitatively assessing screen formats. Results of applying the model to data entry screens support the use of the model. Also described is a critiquing mechanism embedded in a user interface design environment as a demonstration of this approach. (Author/AEF)

This paper proposes a model for a general interface between people and Computer Algebra Systems (CAS). The main features in the CAS interface are data navigation and the possibility of accessing powerful remote machines. This model is based on the idea of session management, in which the main engine of the tool enables interactions with the…
