Room Two · The Evidence Table

The research didn't cause the pattern. It named it.

Why do these same behaviors keep appearing?

The investigation began with observation. The research below helps explain why those same patterns appear again and again.

  1. Research Finding 01

    Teacher Clarity

    A classroom whiteboard showing what students are learning and what success looks like.
    Learning intentions and success criteria posted, and referenced during the lesson.

    When students can say what they are learning and what success looks like, learning accelerates.

  2. Research Finding 02

    Collective Teacher Efficacy

    Teachers around a table, looking at the same student work.

    A staff's shared belief that together they can move learning is among the strongest influences recorded.

    Feedback

    A teacher conferring with one student about the next step.

    Feedback works when it answers where the learner is going and what to do next — not how well they did.

  4. Research Finding 04

    Assessment

    A page of student work annotated with the next step rather than a score.
    Student work annotated with what comes next, not a score.

    Assessment is most powerful when it changes the next lesson rather than reporting the last one.

    Coherence

    Coherence is a shared understanding of the work — it cannot be produced by another initiative.

  1. Research Finding 05

    Professional Learning

    Sustained, job-embedded learning changes practice. One-day events rarely do.

  2. Research Finding 06

    Collaborative Expertise

    Expertise grows fastest when teachers study their own impact together, in structured time.

    Hattie · Collaborative impact

None of this is new. It's simply rarely done together — and rarely held long enough to matter.

From Research to Practice

The research identified the pattern. The classrooms show what that pattern looks like when people begin living it.

This is what it looks like on a Tuesday.

What does the pattern actually look like?

Nothing here is expensive. Almost all of it is a decision about time.
