Lecture Plan: Segmentation and Proofreading

What this document is

This page is a build plan for an instructor assembling a lecture on this unit. It gives the slide sequence, per-slide timing, the points at which figures belong, and the speaker notes that carry the argument. It is a design document, not a rendered deck: there are no slides on this page to project, and nothing here is written to be shown to learners as it stands.

A separately maintained Marp deck for this unit does exist, and it is linked at the foot of this page under Rendered deck artifacts. That deck was authored in its own right and does not follow this plan slide for slide, so treat this page as the teaching design and the Marp file as one existing implementation of it. The learner-facing material is the unit page linked under Connections.

Session profile

• Audience: teams operating proofreading or segmentation-QC workflows.
• Duration: 80 minutes lecture + 15 minutes correction-log exercise.
• Output: prioritized error triage plan and QC dashboard spec.

Slide-by-slide lecture plan

1. Slide 1 (2 min): Title and QC framing
2. Slide 2 (5 min): Why proofreading determines scientific validity
3. Slide 3 (6 min): Error taxonomy
   • merge, split, boundary, identity errors.
4. Slide 4 (6 min): Human-machine division of labor
5. Slide 5 (6 min): Correction protocol (local to global consistency)
6. Slide 6 (6 min): Metrics deep dive I
   • VI, edge precision/recall.
7. Slide 7 (6 min): Metrics deep dive II
   • ERL and synapse-centric F1.
8. Slide 8 (7 min): Prioritization by downstream impact
9. Slide 9 (7 min): Worked correction case I
10. Slide 10 (7 min): Worked correction case II
11. Slide 11 (5 min): Release gating and audit logs
12. Slide 12 (5 min): Team operations and reviewer calibration
13. Slide 13 (5 min): Failure modes and anti-patterns
14. Slide 14 (7 min): Activity + debrief
    • write a correction rationale and metric update.

Figure integration points

• Primary shortlist: course/units/figures/08-segmentation-and-proofreading-selected-v1.md.
• Include at least one before/after correction sequence and one metric dashboard panel.

Speaker notes (expert-level)

• Emphasize high-impact-first correction strategy.
• Pair aggregate metrics with targeted biological sanity checks.

Assessment and artifacts

• Deliverable: correction log with before/after rationale and metric deltas.
• Rubric dimensions: error classification, correction quality, and reproducibility.
