Our product can still be used effectively by all users, though, even those without any CAD knowledge. ![]() Behind the scenes, iScaf uses the powerful AutoCAD drawing engine to draw and estimate scaffold. It can also guide design, not in a prescriptive manner but by providing designers with heuristics and examples of possible ways to address the challenges learners face. iScaf is a fully self-contained software system that can be downloaded and deployed on Microsoft Windows PC or Cloud systems. The framework can provide a basis for developing a theory of pedagogical support and a mechanism to describe successful scaffolding approaches. ![]() Developed through iterative cycles of inductive and theory-based analysis, the framework synthesizes the work of prior design efforts, theoretical arguments, and empirical work in a set of guidelines that are organized around science inquiry practices and the challenges learners face in those practices. In this article, we present a scaffolding design framework addressing scaffolded software tools for science inquiry. However, although there is a growing body of work on scaffolded tools, scaffold design, and the impact of scaffolding, the field has not yet converged on a common theoretical framework that defines rationales and approaches to guide the design of scaffolded tools. ![]() The notion of scaffolding learners to help them succeed in solving problems otherwise too difficult for them is an important idea that has extended into the design of scaffolded software tools for learners.
