A concept map of every lecture, and of everything you study

On a mind map, branches just hang off a centre. On a concept map every link is a statement: low cardiac output decreases blood pressure; monopoly causes deadweight loss. Nila labels each link with the kind of relationship it is — causes, increases, is a type of, is needed for, contrasts with and others — and keeps a lecture to at most 30 concepts, so the map stays readable.

In the research, building a map helps more than studying a finished one, and a map you reconstruct from memory works as retrieval practice. So Nila doesn’t hand you a finished map. As you finish each section, it hides a few links and asks you to fill them in, and gives you a hint when you get one wrong. Read more in do concept maps help you learn?

What sets experts apart is less how many facts they know than how those facts fit together. The Atlas puts every lecture’s map on one canvas, grouped by subject. Where two topics from different lectures or courses meet, Nila draws a dotted line and asks how they connect. Answer it, and the line turns solid when you get it right again in a later review.
