Project-based learning will require more work on the teacher's part to backwards plan from a major student choice project related to the themes. But the experience students have as well as the confidence they gain through working through a project is truly rewarding. Projects can be year long or unit long, pertain to one subject or collaborated with other teachers to integrate multiple subject, done individually or in teams. The best part is that project-based learning has scaffolding built in so students with IEPs and "gifted" students can work on the same project with the same standards and succeed.
