Learner.org seems to have a variety of free video sources for different school subjects. For Spanish, they have the video for the textbook series "Destinos." They also have a college-themed version. That, combined with some scaffolding, would go a long way to help a learner find comprehensible input. (Ray, if you read this....)
For the teacher, they also have a seminar on K-12 language teaching and some arts instruction methods courses that look really interesting.
Also on the free video front, the BBC has a whole host of language tools. The Spanish video was insufferably slow-going for my taste--it felt like "Dora the Explorer" for adults. ("Can you say 'largo?' [pause] ¡Muy bien!) But maybe it's just what some learners need. And maybe later lessons focus on providing comprehensible input.
