H2O is a suite of online classroom tools. In addition to providing a platform to create and distribute digital casebooks, textbooks, and modules [link], H2O also includes a Rotisserie [link] and a Question Tool [link]. The Rotisserie (which we recently moved under its new directory, as part of our efforts to centralize H2O) and the Question Tool are active and being used by teachers and students—and we welcome more users. The Berkman Center plans to continue supporting both into the future, and we would be keen to hear from potential partners interested in these tools. We may also update the tools, and potentially incorporate them (or at least the Rotisserie) into the current H2O theme and suite (which underwent a design overhaul late last spring).
