Maintenance and Generalization of Concepts
A seedling cultivated in a climate-controlled greenhouse often wilts the moment it is transplanted into the unpredictable soil of an open garden. In special education, we face a similar phenomenon: a student with a mild to moderate disability successfully masters a skill at a kidney-shaped table in a resource room, surrounded by highly structured prompts and immediate praise, only to struggle when asked to apply that same skill in the bustling general education classroom a week later. In the science of learning, teaching the initial skill is merely the construction of the greenhouse. Ensuring that the skill survives time and environmental shifts requires entirely different architectural principles.

To bridge the gap between initial acquisition and functional, long-term mastery, special educators must engineer their instruction around two critical pillars: maintenance and generalization.
