# STATION ROTATION LESSON PACK: [LESSON TITLE]
_Unit: U[X] | Module: M[X.X] | Format: 4 Stations x 15 Mins (Total 60-75 Mins)_

## Station Architecture & Timer Overview
- **Classroom Layout:** 4 designated physical zones with clear signage and materials.
- **Rotation Time:** 15 minutes per station + 2 minutes clean transition buffer.
- **Audience Grouping:** Heterogeneous groups of 4-6 students rotating simultaneously.

## Station 1: Teacher-Led Small Group (Guided Inquiry)
- **Goal:** Direct coaching, conceptual check, and resolving misconceptions in real-time.
- **Teacher Script & Inquiry Questions:**
  - *"Look at this code on the monitor. If we call this function 100 times concurrently, what invariant breaks?"*
  - *"Why is value semantics safer than reference semantics when passing across concurrency domains?"*
- **Differentiation Trigger:** If students struggle, demonstrate with physical LEGO / token passing.

---

## Station 2: Collaborative Hands-On Lab (Pair Programming)
- **Goal:** Students work in pairs (Driver / Navigator) to solve a 2-stage challenge.
- **Task Materials:** Pre-loaded project on workstation `Station2_PairChallenge.xcodeproj`.
- **Protocol:** Switch Driver/Navigator roles at the 7-minute audio chime.
- **Success Milestone:** Pass tests `testStation2Stage1()` and `testStation2Stage2()`.

---

## Station 3: Independent Digital Practice (Self-Paced Code Lab)
- **Goal:** Autonomy and individual mastery verification.
- **Student Instructions:**
  1. Open Interactive Code Runner / LMS assignment module.
  2. Complete 5 self-graded micro-challenges (Instant Feedback).
  3. Record completion code into the Station Recording Sheet.

---

## Station 4: Offline Modeling & Architecture (No Screens)
- **Goal:** Cognitive unloading and physical spatial reasoning.
- **Materials:** Whiteboard markers, physical Task Cards deck, and laminated architecture templates.
- **Task:** Hand-draw the data-flow flowchart or match physical cards connecting UI Event $\rightarrow$ State Mutation $\rightarrow$ Screen Re-render.
