ZPD-aligned strategy mapping: deterministic mapping of latent ability θ to explicit instruction, targeted scaffolding, or intellectual challenge¶
Design · All designs
Evidence · no claims cited
Description¶
PsyScore defines a deterministic mapping from estimated ability to a pedagogical control token: explicit directive instruction for struggling learners (θ < −1.0), targeted scaffolding for developing learners (−1.0 ≤ θ ≤ 1.0), and intellectual challenge via Socratic questioning for advanced learners (θ > 1.0). The article states the "ZPD boundary values are designed to operationalize scaffolding theory within a computational framework", and traits with discrimination above 1.2 receive higher prompt attention.
Design Implications¶
Context¶
Requirements¶
- A validated latent ability estimate (θ) from the IRT scorer is required to select the strategy
Constraints¶
- Strategy thresholds (−1.0, 1.0) are design values grounded in the authors' operationalization of scaffolding theory, not empirically derived optima
Target Learners¶
- Essay writers across proficiency levels, from struggling to advanced
Learning Goals¶
- Proficiency-appropriate writing feedback: error correction, guided improvement, or rhetorical refinement
Claims¶
- Psyscore Revision Gains Stratified By Proficiency [+M]
