A Korean-first project page for a Unity research prototype that helps teachers practice responding to students in emotional and behavioral crisis. Introduces the research purpose, working interaction evidence, four research tracks, three-year roadmap, core Korea-US team, and explicit ethical boundaries.
SpeakWise — reasoning evidence traces through AI-mediated oral assessment →
A project page for SpeakWise, an Evidence-Centered Design platform that reframes the oral exam as a process-oriented measurement environment. Covers the problem and research questions, the four-stage ECD pipeline, the four reasoning-evidence-trace types, instructor sensemaking, the current React 19 / Supabase / Gemini Live / Cloudflare architecture, end-to-end student and instructor workflows with narrated demo videos, and the ICOLSEI 2026 poster.

A visually rich guide to what to log before an IVR simulation, VR lab, AI studio, cyber range, or other interactive learning environment becomes impossible to study. Includes ECD, MMLA, privacy, xAPI/Caliper mapping, a live Tetris-like trace simulator, and public-safe starter telemetry templates.
From ISD to LDT →
A beginner-friendly visual guide to how instructional design grew from industrial and wartime training systems into contemporary Learning Design and Technology. Includes an interactive lineage graph, model/theory confusion decoder, DDR/DBR distinction, job-role visualization, and institutional lineage map.
Agentic XR development →
Eleven patterns for building VR/MR with humans-in-the-loop and large language models. Plan files, custom-tool checks, domain MCPs, screenshot loops, ECS-aware debugging, agent-reviewing-agent — illustrated through Unity (Dilmer Valecillos’ basketball MR), IWSDK (Virtual Makerspace, Circuit Playground), Three.js browser games, and the GPT-5.5 vibe-coding wave from X. Includes a Quick Start, Blender MCP asset pipeline, agentic failure-mode catalogue, researcher-specific concerns, glossary, and public-safe starter templates.
Blackboard CXP Modify & Re-Import Workflow →
Diagnose and fix the eight defect classes that surface when a Blackboard ULTRA course archive is exported, edited, and re-imported. Convert-time errors, silent runtime failures, ULTRA × classic-QTI conflicts, and the multi-line FLAGS regex trap — with a downloadable Claude Code / Codex CLI skill bundle and eight pure-stdlib Python fix scripts. KO ↔ EN toggle.
Build Qualtrics surveys by talking to Claude Code →
Eight prompts you can paste into Claude Code (or Codex CLI), in order, to go from a fresh API token to live response export — without writing code yourself. Each step shows the prompt, what the assistant does in reply, and what you see as a result. Closes with one applied case: a TeachPlay perception × efficacy survey for the AI-Enhanced Educational Game Design microcredential.
IRB Amendment Packet Builder →
Turn Obsidian vault project memory, GitHub repo traces, existing IRB baselines, and survey/API records into HRP-502/503-style amendment drafts. Includes a TeachPlay worked example, reviewer-logic map, AI/data-security wording, protocol delta table, consent snippets, recruitment shell, and public-safe starter templates.
From REST API to NLP Dashboard →
A step-by-step bilingual guidebook for collecting REST API or public web data, parsing it into a stable data contract, running versioned NLP enrichment, and building a review-centered dashboard. Includes generated onboarding concept images, a five-step beginner map, FAQ, official references, and starter files for source registry, schema, and Python collection.
Ontology & Qualitative Coding Schemes →
A graduate AI researcher onboarding handbook on the epistemological bridge between formal ontologies and interpretive qualitative coding schemes. Covers shared structure, closed-world/open-world assumptions, reflexivity, coding misconceptions, accountable interpretation, SKOS backbones, and hybrid KG + ENA workflows.
