q2 · i? · design · r2

Efficiency measurement using in-system logs collected during teacher-led sessions, timing production of a complete 45-minute Official Dispatch 5512-compliant lesson including teacher review. Preparation took "approximately 15–20 minutes" versus 3–4 hours manually; the conclusion section cites 30–45 minutes and a 5–8× figure.

"ConnectED achieves a substantial efficiency gain, reducing lesson planning time from 3–4 hours under manual preparation to approximately 15–20 minutes, corresponding to a 9–12×speedup."
