We describe various features and scaffolds embedded in a computer science high school course that is supported by an online learning environment. To develop this course we followed a design-based research approach with problem-based learning as our underlying pedagogy. In collaboration with computer scientists, computer science teachers, and instructional designers, we sought to re-envision Computer Science instruction while creating an innovation that is flexible enough to adapt to local contexts without losing its essence.

- 7. Problem-based learning model Krajcik and Blumenfeld (2006) • learners are presented with a driving question or challenge, • develop a tangible end-product to address the question/challenge, • engage in authentic activities, • collaborate with others & work in groups, • use technology to engage in otherwise impossible activities. • teacher scaffolds
