Sometimes called Kolb's cycle or learning by experience. The four stages are concrete experience, reflective observation, abstract conceptualisation, active experimentation.
Experiential learning is learning that proceeds through direct experience rather than primarily through instruction. The most cited model — David Kolb's four-stage cycle — describes the loop: concrete experience, reflective observation, abstract conceptualisation, active experimentation. Each stage feeds the next; the loop closes when the learner runs the active experiment and produces the next concrete experience.
The practical implication is that experience alone does not produce learning. The reflection and conceptualisation stages are what convert experience into transferable understanding. A student who ships a challenge but skips the reflection stage gets less out of it than a student who runs the full loop.
Ewance challenges run the full Kolb cycle in 1-4 weeks. Concrete experience: pick up a brief and start working. Reflective observation: rubric-based feedback surfaces what landed and what did not. Abstract conceptualisation: revise the model of the problem against the rubric criteria. Active experimentation: the next iteration tests the revised model. The cycle closes; the student moves on with a sharper mental model and a verifiable credential.
The fastest way to know whether challenge-based learning fits you is to ship one.
