This paper presents our attempt to develop a personalized exam preparation tool for Java/OOP classes based on a fine-grained concept model of Java knowledge. Our goal was to explore two most popular student model-based approaches: open student modeling and problem sequencing. The result of our work is a Java exam preparation tool, Knowledge Zoom. The tool combines an open concept-level student model...
Students usually do not study individually; instead, they tend to study collaboratively. The “power of known peers” can be embraced to provide implicit navigation support for collaborative social e-learning environments. In this paper, we present a novel approach to collaborative e-learning through open social student modeling with Progressive Zoom navigation support. Progressive Zoom is a Google-Maps...
A standard Theory of Computation course for undergraduates spans three important topics that are at the core of the computer science (CS) curriculum: automata and languages, computability, and elementary complexity theory. The level of abstraction makes the course demanding to teach, but also to learn. The traditional static ”one size fits all” textbook, or e-textbook, cannot adapt to different students...
