Abstract
The Knowledge Integration Environment (KIE) activities were designed to promote lifelong science learning. This paper describes the partnership process that guided the design as well as the Scaffolded Knowledge Integration framework that gave the partnership a head start on creating effective materials. KIE activities take advantage of internet materials to engage students in debate of science questions like 'how far does light go?', to make scientifically oriented design decisions, and to critique science claims in the popular press. Other papers in this collection describe the design studies carried out to improve KIE activities. These studies have implications for improving the Scaffolded Knowledge Integration framework and can inform future designers of science instruction.
