Khan progress mirror

Mirror outside mastery into PeerTutor practice

Khan Academy progress has to be entered from the student or tutor report. Khan does not provide a supported public progress API, so this mirror stores unit status locally and uses it to target PeerTutor checks.

    Global Change

    • Use ozone depletion, climate change, ocean warming, acidification, invasive species, and biodiversity loss.
    • Evaluate global-scale solutions and limits.

    Practice: Write a global-change argument with mechanism, evidence, proposed solution, and tradeoff.

    Unit work plan
    1. 1
      Source study

      Start with AP Environmental Science and AP/College Environmental Science. Take notes until you can explain: Use ozone depletion, climate change, ocean warming, acidification, invasive species, and biodiversity loss.

    2. 2
      Foundation gate

      Do the first sequenced checks until the definitions, vocabulary, and setup are correct without hints.

    3. 3
      Transfer gate

      Produce the assignment artifact, then pass the application and analysis checks tied to: Write a global-change argument with mechanism, evidence, proposed solution, and tradeoff.

    4. 4
      Repair loop

      Any miss becomes an error-log entry, a clean redo, and one nearby transfer problem before advancing.

    5. 5
      Tutor handoff

      Bring your attempted work, the exact missed check, and one question about: Evaluate global-scale solutions and limits.

    Sequenced original practice checks

    Move in order: foundation, transfer, analysis, timed readiness, then metacognitive repair.
