A Model-driven Approach to the development of a PBL Script Editor

Designing a pedagogically sound and technically executable collaboration script is a highly complex, time-consuming and error-prone task. This paper presents a model-driven approach to enable practitioners to design online PBL courses. Adopting this technical approach, we developed a PBL scripting language that provides natural concepts for the teacher to use in PBL practices. Based on the PBL scripting language, we developed a PBL script editor that facilitates teachers to design, communicate, customize, and reuse PBL scripts. In addition, it provides functions to transform a PBL script to a unit of learning (UoL) represented in IMS Learning Design (LD), which can be executed in an IMS LD run-time environment to scaffold PBL processes.
