Online supplemental courses

Next month, March 5th to be exact, the first MITx course will begin. The online course, Circuits and Electronics, will be offered for free and give students the opportunity to earn a certificate of content mastery through an online assessment. MITx is a promising program for students interested in the courses offered. The content mastery certificate opportunity takes open learning to the next step beyond simply watching lectures and accessing course hand-outs. (from Free Technology for Teachers)
