DFKI DFKI Research Reports (RR) 02-01 2002.


This report describes the feedback in ActiveMath, a learning environment for mathematics. In particular, we distinguish local and global feedbacks.For the global feedback we describe the blackboard-architecture with its reusable and easily modifiable components, specify the current evaluators of the learners actions, and present the user-adaptive global learning suggestions implemented so far. The report also describes the design of the suggestion user interface that is based on empirical results about feedback described in the literature. Finally, remaining questions that need to be clarified by empirical research are discussed.
