Code.org's Adaptive pathway now skips checkpoints students have already shown they know.

edtechadaptive-learningai-tutorai-labassessments
◆Current state
Code.org ships near-daily builds whose user-visible work centers on the Adaptive pathway, AI Lab and quizzes. This week Adaptive began routing its map from collected evidence and skipping demonstrated checkpoints, added step navigation and step validation, and got routing flags on the hoai2026 pathway. AI Lab now exposes record ids in tables and cards, and quizzes gained a matching question type.
◆Where it's heading
The Adaptive pathway is moving from logged diagnostics toward routing that personalizes the course map, with the AI Tutor built into each step; the hoai2026 pathway looks like the vehicle for it. Alongside it, the Lab2 migration (Sprite Lab, Web Lab 2) and an RDS Proxy switch for read replicas show platform work running in parallel.
◆Prediction
Expect the hoai2026 Adaptive pathway to reach a broader classroom pilot with teacher-facing views of routing decisions, and AI Lab project saving to land next.

    Adaptive judges project steps on each accepted build

    Adaptive now judges a project step's work each time the student accepts a build, and adaptive levels get an updated tutor sidebar. It tightens the evidence loop from yesterday's step checks, with Langfuse session tracing added to watch how the routing behaves.

    Adaptive uses project-step checks as evidence; AI Lab saves projects

    Adaptive now takes evidence from checks on a project step's work, which feeds the evidence-based routing built over the past week. AI Lab gets project saving, Quiz gets a multi-select builder, and OAuth and LTI sign-ins now sign out the previous student on shared devices.

    Adaptive routing flags on hoai2026; AI Lab shows record ids

    Routing flags and a project description land on the hoai2026 Adaptive pathway, a small step that ties this week's evidence-based routing to a named course. AI Lab adds an id column to tables, cards and the level editor, which makes datasets easier to reference in lessons.

    Read-replica queries move to RDS Proxy

    An infrastructure-only build that moves read-replica queries from ProxySQL to RDS Proxy. Students and teachers won't see a change.

    Quiz matching builder; groundwork for Lesson Deep Dive

    Mostly operations work (weighted-random load balancing, Sentry deploy tracking), plus a builder for quiz matching questions, AI Lab grade counts that follow table filters, and an OpenAI key for a new Lesson Deep Dive feature. The Deep Dive wiring hints at another AI-assisted surface coming.

    Adaptive adds step navigation and per-step validation history

    Adaptive levels gain step navigation, return-to-last-step, and a validation block that keeps a history of checks on each project step. AI Lab gets filters across its views, and the AI Tutor gets its own answer type. This makes the Adaptive pathway usable across sessions.
