Organizing principles for science education partnerships: Case studies of students' learning about 'rats in space' and 'deformed frogs'

We describe how science education partnerships composed of educational rese archers, technologists, classroom teachers, natural scientists, and pedagog y experts can create effective instructional innovations using Internet tec hnologies. We show that our Scaffolded Knowledge Integration framework give s partnerships a head start on effective designs. We illustrate this proces s With the Deformed Frogs partnership and the Rats in Space partnership. We conclude with suggestions for future partnerships.
