Scaffolding via level-gated progression and hearts in Duolingo

Description

The article describes Duolingo's design as scaffolding, in which learners progress into more advanced levels once they show competence at the previous level. A heart system enforces this: users lose hearts for incorrect answers and a session ends when all hearts are lost, so the user "must answer items correctly before they are able to complete the new material." Content is grouped into manageable units, and negative feedback identifies incorrect answers users may learn from.

Design Implications
