Look for 1: Students connect convection → plate movement → surface features across all four content weeks
Look for 2: Students synthesize plate boundary types with eruption styles and Earth's interior structure
Look for 3: Students use evidence from multiple weeks to construct cross-cutting explanations
Look for 4: Students demonstrate vocabulary fluency (asthenosphere, subduction, viscosity, seismic waves)
Look for 5: Students self-identify weak areas before Part 2 cumulative assessment
Look for 1: Section A (Plate Boundaries, 15 pts): Students classify boundary types and predict geological features
Look for 2: Section B (Seafloor Evidence, 15 pts): Students interpret magnetic stripes, rock ages, and continental matching
Look for 3: Section C (Volcanic Systems, 15 pts): Students connect magma properties to eruption styles and hazard assessment
Look for 4: Section D (Earth's Interior, 15 pts): Students use seismic evidence to explain layer structure and properties
Look for 1: Students demonstrate corrected understanding of 'plates float on magma' misconception
Look for 2: Students demonstrate corrected understanding of 'continents move fast' misconception
Look for 3: Students demonstrate corrected understanding of 'earthquakes are random' misconception
Look for 4: Students explain WHY the misconception is wrong using evidence, not just stating the correct answer
Look for 5: Two-tier format reveals whether correct answers reflect genuine understanding or lucky guessing
MISCONCEPTION: Plates float on liquid magma like boats on water
Correct: Plates rest on the asthenosphere (plastic solid, not liquid); S-waves travel through the mantle proving it's solid. Convection in this plastic-like solid drives movement.
Intervention: If this misconception persists through assessment, schedule targeted re-teach using the S-wave shadow zone diagram from W4 Station 1.
MISCONCEPTION: Continents move fast enough to notice in a human lifetime
Correct: Plates move 1-10 cm/year. The Atlantic widens ~2.5 cm/year. GPS technology can now detect this motion, but it's imperceptible to human senses.
Intervention: If this persists, return to the W2 calculation: 2.5 cm/year × 25 years = 62.5 cm. Tangible but tiny. Then scale up: 2.5 cm/year × 200 million years = 5,000 km (Atlantic Ocean width).
MISCONCEPTION: Earthquakes happen randomly across Earth's surface
Correct: ~90% of earthquakes occur along plate boundaries. The distribution is highly predictable from plate geometry.
Intervention: If this persists, return to the W1 earthquake map. Count earthquakes at boundaries vs. mid-plate. The pattern is overwhelming — this should be the easiest misconception to correct with data.

Data Sources to Review
- Part 2 section scores (A vs. B vs. C vs. D) to identify weakest content area across the class
- Part 3 misconception persistence rates: percentage of students still selecting misconception answers after 4 weeks
- Part 1 synthesis quality: do students connect across weeks or treat each topic as isolated?
- DNPG checkpoint scores (F2 open-response questions): manually grade for depth of explanation
