CILC If you don’t know the Center for Interactive Learning and Collaboration, it’s time to make its acquaintance. This non-profit hosts thousands of “content providers” — people who have something to say and a great way to say it through live, interactive video-conferences with classrooms. David and the other iNK authors offer reasonably-priced one-hour video-conferences on a wide range of subjects through CILC. Find out about iNK’s more extensive programs here.
