Hypothesis in Teaching and Learning (length: 7:07) from the Hypothes.is Pilot Technology Workshop:

Hypothes.is brings discussion directly to course content by enabling students and teachers to add comments and start conversations in the margins of their texts. In this workshop, learn how to use sentence-level note taking or critique on top of classroom readings, news, blogs, scientific articles, books, and other documents. We will also discuss ways to integrate Hypothes.is into your teaching strategy.
