The Lattice model

Teach the move behind the answer.

Subject knowledge matters. So does knowing when to question an assumption, compare models, seek disconfirming evidence, or change course. Lattice treats those moves as teachable.

A repeated learning cycle

Reasoning becomes visible through action.

  1. 01

    Observe

    Identify the phenomenon, separate data from interpretation, and notice what is missing.

  2. 02

    Model

    Express a mechanism in words, diagrams, mathematics, or code.

  3. 03

    Challenge

    Test assumptions, generate alternatives, and look for evidence that could change the claim.

  4. 04

    Transfer

    Use the same reasoning move in a less familiar context and explain why it still applies.

Four connected systems

Adaptive does not have to mean opaque.

Each recommendation can be traced to curriculum goals, observable work, and a teacher-adjustable hypothesis about what the learner needs next.

01

Curriculum graph

Links concepts, representations, misconceptions, prerequisites, and transfer patterns—not just chapters.

  • Cambridge 0625 seed map
  • Teacher-editable sequences
  • Source-linked content
02

Learner model

Updates provisional beliefs about strategies demonstrated in recent work.

  • Evidence trails
  • Confidence ranges
  • No fixed ability labels
03

Inquiry tutor

Selects the smallest prompt likely to move reasoning forward without taking ownership away.

  • Hint fading
  • Counterexample prompts
  • Multiple representations
04

Teacher console

Surfaces class patterns, uncertain diagnoses, and representative student work.

  • Lesson-level signals
  • Teacher override
  • Exportable evidence

A different optimization target

From completion to capability.

Typical adaptive practiceLattice

Predict the next correct answer

Identify the next useful reasoning move

Shorten time to completion

Increase productive independence

Model mastery as one score

Show concepts, strategies, evidence, and uncertainty

Give stronger hints after failure

Change representation or challenge the underlying model

Design principles

Guardrails are part of the pedagogy.

Agency over compliance

The student makes the claim; the system creates conditions for testing it.

Uncertainty made explicit

Diagnosis is presented as a revisable hypothesis supported by visible evidence.

Teachers remain authors

Educators control learning goals, acceptable methods, pacing, and intervention.
