SCY aims to take science education to the next level by developing a flexible, open-ended learning environment that engages and empowers adolescent learners. Within this learning environment -called SCY-Lab- students embark on authentic 'SCY missions' that can be completed through constructive and productive learning activities. The SCY philosophy of learning is 'learning by designing artifacts'. SCY-Lab provides adaptive support for these activities through providing students with pedagogical scaffolds, collaboration facilities, and peer assessment and social tagging tools. Students' products (so-called Emerging Learning Objects) are saved in a repository and can be re-used by learners themselves and by other learners.
