500+ free videos with exercises from Italy's main italiano-per-stranieri publisher.
Details
ALMA Edizioni's free web-TV: grammar series like Grammatica Caffè (by Roberto Tartaglione), vocabulary, culture and teacher-training sections, each video paired with didactic activities. Because it comes from a textbook publisher, the sequencing and terminology line up with what you'd meet in an Italian classroom. Free to watch; the linked coursebooks are paid. Navigation is a bit of a maze — browse by section rather than hunting.
