Crucible Teacher OS / The Global STEM Teaching Operating System

Every teacher gets a world-class STEM coach.

Crucible doesn't replace teachers. It gives every teacher the leverage of a master curriculum designer, lab technician, assessment expert, and data analyst — all generated from real student evidence, not guesswork.

Today's Teaching Move — Period 3 Biology
Most students stabilized the ecosystem, but 62% could not explain the role of limiting factors.
Run a 7-minute discussion using the "Vanishing Green" replay. Then assign the one-variable intervention challenge to Group B.
Group A — Variable Control
Focus: Experimentation
Have students change only ONE variable to solve the crash. Discuss which variable and why.
Group B — Graph Evidence
Focus: Evidence Use
Require students to circle evidence on the population graph before writing any claims in their CER.
Exit Ticket
Explain why plant population fell before herbivore population crashed. Use the word "because" and cite one piece of evidence from the graph.
Not a Dashboard — A Cockpit

Five questions answered every day.

Teachers don't need pretty graphs. They need a cockpit that tells them what to do next. Crucible answers the five questions every teacher needs answered before, during, and after class.

1
What should I teach?
The platform recommends the next lesson based on class data and standards progress.
2
Who needs help?
Students grouped by misconception, not just score. See exactly who is stuck and why.
3
What are they missing?
Precise diagnosis: "understands visually but cannot explain with graph evidence."
4
How do I fix it?
Specific teaching moves: "Show replay tick 40-80. Ask what changed first. Write one sentence with 'because.'"
5
How do I prove it?
Artifacts, reports, rubrics, and standards evidence. Exportable. Printable. Parent-ready.
AI-Powered Teaching Moves

Six copilot actions generated from real evidence.

Every copilot output is generated from your classroom's actual student data — not generic templates. The AI reads skill models, misconceptions, predictions, artifacts, and session telemetry to produce specific, actionable teaching moves.

01
Lesson Plans
Full 45-minute lesson with warm-up, standards-aligned activities, differentiation, small-group time, and closing exit ticket.
02
Small Groups
Students clustered by skill deficit. Each group gets a specific activity, materials, success criteria, and teacher script.
03
Discussion Questions
Eight questions ordered from accessible to challenging. Each includes purpose, expected struggle, and follow-up probes.
04
Exit Tickets
Quick 5-minute assessment targeting the weakest class skill. Three multiple choice + one open response with rubric.
05
Parent Summaries
Parent-friendly narrative per student: strengths, growth areas, home connection activities, and next steps.
06
Intervention Plans
Targeted 2-week plan for struggling students: daily sessions, specific missions, progress indicators, escalation criteria.
Adaptive Diagnostics

Assign diagnostics. View scores. Personalize learning.

Send adaptive diagnostics to your classroom with one click. Students complete them in 10-15 minutes. Results flow back into Crucible automatically — calibrating the simulation to each student's baseline.

1
Assign with one click.
Choose an exam type (ecology, biology, environmental science, systems thinking). Set an optional deadline and message. Every student gets notified.
2
Track completion.
See who has completed, who hasn't, and the class completion rate — all in real time from your dashboard.
3
View domain scores.
Per-student score breakdowns: estimated score, confidence interval, domain accuracy, skill masteries, priority areas, and score history over time.
Before, During & After Class

The platform works while you don't.

Crucible becomes indispensable when teachers can teach better with it than without it. Every step of the teaching day is supported.

Before Class
Prepared in minutes.
  • Lesson plan generated from class data
  • Mission assigned to classroom
  • Student prerequisites checked
  • Vocabulary preview ready
  • Misconceptions predicted
During Class
Real-time insight.
  • Live view of student progress
  • Struggling students flagged
  • Discussion prompts surfaced
  • Class replay moments saved
  • Quick intervention groups created
After Class
Evidence delivered.
  • Artifacts graded or pre-scored
  • Reports generated and exportable
  • Next lesson recommended
  • Parent summaries available
  • Remediation/enrichment assigned
Trusted Evidence of Learning

Four types of evidence. Zero guesswork.

The platform must prove students are learning transferable concepts, not just becoming good at the game. Every claim has evidence behind it.

Behavioral
What Students Do
Predictions, interventions, lens usage, variable control, time to recovery, strategy transfer across biomes.
Written
What Students Write
Claims, evidence, reasoning (CER), design memos, reflections, lab-style reports tied to simulation data.
Quantitative
What Students Calculate
Graph interpretation, rate of change estimation, population predictions, competitive advantage calculations.
Oral
What Students Discuss
Discussion prompts, teacher-scored debate, peer explanation, group design reviews surfaced by the copilot.
