Sometimes called simulation training. Distinct from a real challenge — simulations have known scenarios; real challenges have open outcomes.
Simulation-based learning uses realistic simulations of work or scenarios to develop skill in contexts where real-world practice is impractical or unsafe — flight simulators in aviation, clinical scenarios in medical training, market simulations in finance. The strength is fidelity in a controlled environment; the limit is that the scenario is set up by someone, with a known frame.
For early-career portfolio building, simulation-based learning produces a particular kind of evidence — completion of a known scenario — which is weaker signal than evidence of work on a real, ill-structured problem. Both have a role; neither replaces the other.
Ewance challenges sit on the real-problem end of the spectrum, not the simulation end. A Forage simulation gives the student a taste of a known scenario; an Ewance challenge gives the student a real brief with rubric-based assessment. Both produce learning, but the credentials they generate signal different things to recruiters.
The fastest way to know whether challenge-based learning fits you is to ship one.
