Apply constructivist learning design principles

Design developmentally appropriate curriculum using schema and constructivism

Diagnosing why a learner is stuck (schema mismatch vs. developmental impossibility) and engineering learning situations where disequilibrium prompts productive restructuring

• · learner age or developmental stage
• · existing schemas (prior knowledge inventory)
• · new concept to be learned
• · available concrete/manipulable materials

• · curriculum sequence respecting assimilation/accommodation loop
• · disequilibrium point (where learning can happen)
• · scaffolding strategy (support the restructuring)
• · concrete-to-abstract progression
• · readiness check: domain-specific expertise vs. developmental stage

Understanding of learner's current schemas; access to age-appropriate materials; recognition that readiness varies by domain (not universal)

Pure assimilation (no new learning, just review); skipping accommodation (confusion without support); forcing abstract instruction before concrete schema exists; age-stage confusion

• · Piaget's assimilation/accommodation loop centered (core mechanism, not just background)
• · Four stages described with achievements and limitations (not as rigid gates but as typical patterns)
• · Conservation task cited as evidence of stage transition (logical operation development)
• · Distinction between developmental readiness and domain expertise explicitly stated
