Peer reviewedWu, Hsin-Kai; Krajcik, Joseph S.; Soloway, Elliot – Journal of Research in Science Teaching, 2001
Investigates how students develop an understanding of chemical representations with the aid of a computer-based visualizing too called eChem that allows them to build molecular models and view multiple representations simultaneously. Involves 11th grade students (n=71) at a small public high school and examines the changes in students'…

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. However, although there is a growing body of work on scaffolded tools, scaffold design, and the impact of scaffolding, the field has not yet…
