WORDMATH is a computer-based learning environment designed to teach word problem solving to 9–12 year old students in Singapore primary schools. The students are taught to solve word problem solving using a locally developed approach called model building. Students will draw blocks to represent part-whole relationships depicted in the problem statement, and by drawing such blocks, they can visualize the problem more clearly and are able to make tacit knowledge explicit. The design of WORDMATH is based on some of the teaching methods of the cognitive apprenticeship approach. In this paper, we describe how these teaching methods have been implemented in the current version of the tutor.

Presents a heuristic solution to the dynamic transportation planning problem using a blackboard-based architectural approach. The proposed Intelligent Transportation Planning System is based on the Generic Blackboard Shell (GBS) and comprises traffic simulation and vehicle locomotion models as well as various problem-solving strategies. The realised dynamic vehicle assignment and routing strategies modify deployment plans in response to changes in traffic conditions and to new passenger requests. The effectiveness of the system has been demonstrated in a simulation using a fleet of taxi robots with randomly generated road networks, background traffic load and passenger requests, and compared with commonly-used approaches.
