In this paper, we describe the web-based scaffolded dynamic simulation system (PRES-on) designed for pre-service teachers. PRES-on will act as a cognitive tool for learners to identify and articulate their thought processes in representing and solving problems using a set of building block icons (stocks, flows, converters, and connecters). It is a generic tool that is capable of supporting multidisciplinary learning which is highly important in today's context. PRES-on is designed to be used in an open learning environment that seeks to promote and cultivate divergent thinking and in situations where multiple perspectives are valued. The mathematical component of PRES-on will simulate the dynamic behaviour of the problem representation and capture complex patterns of such behaviours. In addition, as a web-based engine, learners can readily build and share their problem representation with their peers. Being one of the first initiatives to develop a web-based scaffolded dynamic simulation system for problem solving purpose, PRES-on will inform our understanding on how new technological development could enhance learning in environments that involve multidisciplinary problem solving. This project forms part of the continuing effort to bridge theory and practice as we aim to advance the pedagogical application of PRES-on through design experiment.
