Cross-comparison of the educator study (Section 3.1) and the automated metric evaluation (Section 3.2). The article reports "both evaluations identifiedcoherenceandtemporal alignmentas the dimensions most significantly enhanced by the PedaCo pipeline", suggesting complementary rather than redundant verification.

"both evaluations identifiedcoherenceandtemporal alignmentas the dimensions most significantly enhanced by the PedaCo pipeline. Educators ranked coherence among the top three improvements"

• 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 — related
• The pipeline feasibly produces coherent, synchronized educational videos from textbook queries, integrating retrieval, image generation, animation, and speech — related
• The automated scoring system's agreement with human raters varied widely by dimension, with information fidelity showing a weak, non-significant correlation — related
