(4) Branch/House/Track #4: Inclusion, Diversity, Equity, Access, & Social Justice (IDEAS) The current House 4 frame includes a gallery and a home-like atmosphere for presentations or events (shown above). As of January 29, 2026, it has not been decorated or assigned to host regular activities. BH-05   Science, Technology, Engineering & Mathematics (STEM)   Frame Type Branch House Status OPEN Track / Branch STEM Education Capacity 50 users FrameVR URL https://framevr.io/house5-stem   Frame Purpose The disciplinary home for immersive learning research and practice in STEM fields. STEM is the most heavily published domain in XR education research — this Frame surfaces and organises that evidence base while connecting it to the broader iLRN ecosystem.   Frame type context: Branch House — persistent disciplinary anchor. Note that current literature skews heavily toward STEM; this Frame curators should actively surface non-STEM connections and resist silo effects.   1   Ownership & Governance Frame Lead / Owner   Content Contributors   Technical Steward   Accessibility Reviewer   Last Updated     2   Learning Design Requirements   —   + UDL 3.0 :   expert/novice distinction is acutely relevant in STEM: prior knowledge gaps between participants can be large. The Frame must support both introductory and advanced engagement without either overwhelming newcomers or boring domain experts.   UDL: XR offers powerful Representation options for abstract STEM concepts (molecular structures, mathematical spaces, physics simulations). The Frame should model this — not just talk about it. At least one board should demonstrate an immersive representation of a STEM concept.     Universal Requirements (all frames) Criterion / Pass Threshold ☐ Purpose statement posted in Frame at entry zone Visible within 10 sec of entering ☐ Orientation cues for newcomers (what this space is, what to do) Confirmed by blind test with volunteer ☐ Asynchronous contribution pathway available (forum, Codex, Discord link) At least 1 async pathway; URL live ☐ Content accessible in text form via Codex (Representation — UDL) Codex page live and linked in Frame ☐ No colour-only navigation cues — all zones/portals have text labels Confirmed by reviewer ☐ Emotional tone is welcoming; language is jargon-free at entry Confirmed by reviewer external to Frame team   Frame-Specific Requirements Criterion / Pass Threshold ☐ At least one board demonstrates an immersive/XR representation of a STEM concept (not just text description) Content confirmed with branch contributor ☐ Non-STEM connections signposted (counter-silo measure) At least 1 cross-branch link present   3   Design & Build Checklist   Layout & Purpose Criterion / Pass Threshold ☐ Frame purpose defined in one sentence, posted at entry Written purpose statement visible ☐ Environment size matches use case Appropriate environment selected; not over/undersized ☐ Central meeting / focal area identifiable within 10–15 sec Walk-through test by reviewer   Navigation Criterion / Pass Threshold ☐ Minimum 2 outgoing portal links to other Frames ≥ 2 portals; 0 dead ends ☐ Consistent portal visual language (campus-wide asset style) Matches campus portal standard ☐ Navigation path from entry to any key area ≤ 15 seconds Timed walk-through by reviewer ☐ All portal destinations confirmed live Click-tested by reviewer   Signage Criterion / Pass Threshold ☐ All text legible on mobile screen at default eye level without zooming Phone screen test ☐ No signage relies on colour alone Label or icon accompanies all colour-coded elements   Zone Setup (if zones are used) Criterion / Pass Threshold ☐ 'Restrict all assets to zones' enabled if zones are in use Frame settings → restrict assets = ON ☐ Each zone has a named purpose Zone names visible in Frame settings   4   Performance & Asset Budget   — check via Frame Settings → Performance Rating or ?debug=true FrameVR targets: ≤ 200 draw calls · ≤ 130,000 active faces · ≤ 20 materials.
