NORMIT: a data normalization tutor

Overview of NORMIT
NORMIT is an ITS that teaches data normalization. NORMIT is a problem-solving environment, in which students can improve their skills. We assume that students would already be familiar with the data normalization theory from lecture, but the system does provide some support for acquiring domain knowledge. We require the student to go through the following steps in NORMIT:
NORMIT is an adaptive system. The tailoring of instruction is done in two ways: by adapting the level of complexity of problems and by generating informative feedback messages. The architecture of the system is illustrated in the following figure.
The interface of the system was developed by Li Chen and Melinda Marshall.
NORMIT was used in COSC226 (the introductory database course) for the first time in 2002. The results of the evaluation are available from the paper presented at the Workshop on Meta-cognition and self-regulation in learning with metacognitive tools, associated with the 11th international conference on Artificial Intelligence in Education, AIED 2003 (Sydney, July 20-24, 2003).
