The Knowledge Integration Environment (KIE) activities were designed to pro
mote lifelong science learning. This paper describes the partnership proces
s that guided the design as well as the Scaffolded Knowledge Integration fr
amework that gave the partnership a head start on creating effective materi
als. KIE activities take advantage of internet materials to engage students
in debate of science questions like 'how far does light go?', to make scie
ntifically 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 fu
ture designers of science instruction.
