Description

PedaCo is a human-AI collaborative software system that helps educators generate and evaluate instructional videos using CTML-informed script review and automated post-synthesis metrics.

Components

• PedaCo: a dual gatekeeping human-AI video co-creation system: PedaCo (Pedagogical Co-creation) is a human-AI collaborative system that "integrates two complementary gatekeeping mechanisms: reviewing scripts through CTML-informed criteria, and an automated metric evaluating finished videos against computationally measurable CTML dimensions." Layer 1 intervenes before rendering: an LLM generates an initial script, an AI reviewer produces principle-organized feedback identifying potential violations, and the educator decides what to accept, revise, or regenerate. Layer 2 performs post-synthesis evaluation, automating five dimensions: coherence, redundancy, temporal contiguity, modality, and image quality.

Claims

• CTML-guided educator review of AI video scripts yields statistically significant improvements across all 12 CTML principles and overall instructional validity [+M]
• Automated CTML metrics show significant improvement in temporal contiguity and coherence for CTML-informed videos, while modality, redundancy, and image quality show no significant difference [+M]
