This document discusses multi-mode learning and sustainable approaches for opening up higher education through low-cost methods. It proposes using a standard college module format of 12 weeks with 2 hours of recorded lecture material, links to open educational resources, forums for support and peer assessment, and quizzes for a flipped classroom model. This could then be opened up as a MOOC. The document also outlines principles for low-cost MOOC production, including using simple video production without extra editing or animations, reusing open educational resources, and employing objective assessments and peer review that can scale. The goal is to collect and share these low-cost methods through a website and community forum via a project called moocs4all.
