The Knowledge Map was a feature on Khan Academy which contained a starry night, containing all of the stars. The stars represent lessons. Yellow stars with a blue border are lessons, user are proficient at, green borders mean recommended lessons, and others are lessons that are not recommended. An orange border means a lesson user should review. It also told the user how skills are connected to each other. The Knowledge Map also has a navigation bar, with which students could search for a particular skill. Since the Learning Dashboard came out, the feature is no longer available as of August 2013.
