An Online Platform for Problem-Based Learning with Operational Concepts Map

Abstract

Problem-based learning (PBL) encourages learners to acquire new knowledge through cognitive model development and hypotheses-deduction process. Graphical modeling tools, such as concept map, can help learners to exteriorize the process of knowledge construction and visualize learner's cognitive model to support meaningful learning. But few of those tools integrate hypothesis-reasoning mechanism into the process to support the discovery of knowledge deficiencies and foster in-depth reflection. To that end, this paper proposes a novel graphical tool, operational concept map (OCM), for supporting the PBL. In OCM, it combines the merits of conceptual modeling tool and computer-based simulation. The OCM not only inherits all basic functions of concept map, also facilitates the learning-by-doing approach for problem solving. Application of the proposed idea is illustrated in learning a well-known sort algorithm, bubble sort, in the sort problem.
