Portfolio of edX style pre-class physics questions

MIT's freshman physics class uses edX materials.  Among these was a sequence of "pre-class questions" and short articles intended to encourage students to read text materials and be aware of the basic features of the upcoming work that would be done in class.  The goal was to introduce basic ideas and vocabulary and to motivate rather than to assess consideration by students.
