Sara-Elizabeth Cottrell of Musicuentos has an ongoing list of activities that students can choose from for their own weekly fluency activities, which can involve different levels of student accountability and evidence.
Cottrell also has a unique take on final projects, wherein students design their own "exams."
Bethanie Drew: I adapted Sara-Elizabeth's idea for my Spanish 3 class and called it "Choose Your Own Adventure". Students rated it highly, and I'll keep it for next year. The descriptions of the options are here, and the student log is here. I'd love to explore making this a paperless project via Evernote for next year.
