Sometimes called purposeful practice. The empirical research is associated with K. Anders Ericsson; the practical version drops the academic framing.
Deliberate practice is practice with a specific learning goal, immediate feedback against that goal, and progressive difficulty over time. It is distinct from repetition that does not improve skill — playing five thousand mediocre rounds of golf does not produce a scratch golfer; targeting a specific element of swing mechanics with a coach does.
For a student, the practical version is straightforward. Pick a specific skill component, find a way to get rapid feedback on it, work on the boundary of what you can already do. The combination is what builds capability faster than time-on-task alone.
Ewance challenges are designed for deliberate practice. Each one targets a specific cluster of skills, ships rubric-based feedback within a defined window, and is calibrated to the student's academic track so the difficulty pushes back. A student who works through several challenges in their target domain accumulates the kind of feedback-shaped practice that compounds.
The fastest way to know whether challenge-based learning fits you is to ship one.
