This document discusses MOOCs (Massive Open Online Courses) and their integration into traditional school environments. It provides general principles and practical considerations for MOOCs, including that they are time-based with weekly videos, quizzes and assignments. Larger assignments use peer assessment. MOOCs can enhance learning for students by allowing them to learn from the best instructors and prepare for further study, while educators can keep updated and broaden perspectives. The document also briefly introduces alternatives like TED-Ed and Google Coursebuilder that may be better fits for some than larger MOOCs.
