Challenge-Point Framework

A motor-learning theory proposed by Guadagnoli and Lee (2004) which holds that learning is optimised when the difficulty of a task is appropriately matched to the learner's current skill level. Tasks that are too easy provide little information to learn from, while tasks that are too hard overwhelm the learner. The framework underpins arguments for tailoring challenge in games, training, and assistive interventions, and supports the case for handicapping and dynamic difficulty adjustment as accessibility tools: by moderating difficulty to an individual's ability, systems can sustain progression and engagement for learners or players who would otherwise disengage.
