# Edtech Industry Trends

## 매 한 줄
> **"매 AI tutor 의 mass adoption + skill-based credentialing 의 rise"**. 2020 COVID 의 remote-learning 폭발 이후, 2023 GPT-4 의 ChatGPT 의 학습 의 disrupt — 2026 는 personalized AI tutor (Khanmigo, Duolingo Max), micro-credential (Coursera, Open Badges), 그리고 LXP (Learning Experience Platform) 의 LMS 의 대체 의 dominate trend.

## 매 핵심

### 매 2026 핵심 trend
- **AI tutor 의 ubiquity**: Khanmigo, Duolingo Max, ChatGPT for Education.
- **Adaptive learning**: knowledge tracing (DKT, BKT), spaced-repetition.
- **Micro-credential**: stackable certificate, Open Badges 3.0, blockchain anchored.
- **VR/AR**: Meta Quest for Education, immersive lab.
- **Skills-based hiring**: degree-optional, portfolio + assessment.
- **Decline of MOOC giants**: Coursera/edX 의 plateau, niche bootcamp 의 rise.

### 매 Tech stack
- **Frontend**: Next.js, React Native, Unity (immersive).
- **AI**: GPT-5, Claude Opus 4.7, Gemini 2.5, fine-tuned tutor model.
- **Backend**: PostgreSQL + pgvector, Redis, Kafka.
- **Standard**: LTI 1.3, xAPI/cmi5, Open Badges, IMS Caliper.

### 매 응용
1. K-12 의 personalized math tutor (Khan Academy).
2. Higher-ed 의 AI TA (Georgia Tech Jill Watson 후속).
3. Corporate L&D 의 skill graph (Degreed, Cornerstone).
4. Language (Duolingo, Speak) 의 conversational AI.

## 💻 패턴

### LTI 1.3 의 LMS launch
```typescript
import jwt from 'jsonwebtoken';

export async function ltiLaunch(req, res) {
  const idToken = req.body.id_token;
  const decoded = jwt.verify(idToken, getKey, {
    algorithms: ['RS256'],
    audience: process.env.LTI_CLIENT_ID,
    issuer: process.env.LTI_PLATFORM_ISSUER,
  });
  const user = {
    sub: decoded.sub,
    role: decoded['https://purl.imsglobal.org/spec/lti/claim/roles'],
    contextId: decoded['https://purl.imsglobal.org/spec/lti/claim/context'].id,
  };
  req.session.lti = user;
  res.redirect('/activity');
}
```

### Adaptive item selection (BKT)
```typescript
// Bayesian Knowledge Tracing
function bktUpdate(p_known: number, correct: boolean,
                   p_T = 0.1, p_S = 0.1, p_G = 0.2) {
  const p_obs = correct
    ? (p_known * (1 - p_S)) / (p_known * (1 - p_S) + (1 - p_known) * p_G)
    : (p_known * p_S) / (p_known * p_S + (1 - p_known) * (1 - p_G));
  return p_obs + (1 - p_obs) * p_T;  // 매 mastery prob 의 update
}

function nextItem(skillStates, items) {
  // 매 ZPD: mastery 0.4-0.7 의 item 의 prefer
  return items
    .map(i => ({ i, score: Math.abs(skillStates[i.skill] - 0.55) }))
    .sort((a, b) => a.score - b.score)[0].i;
}
```

### AI tutor 의 Socratic prompt
```typescript
const tutorSystemPrompt = `You are a Socratic tutor. NEVER give the answer.
- Ask one guiding question at a time.
- If student is stuck, decompose the problem.
- Validate effort, gently correct misconceptions.
- Use student's prior turn to scaffold.
- After 3 unsuccessful hints, offer worked example, not answer.

Subject: ${subject}
Student grade: ${grade}
Misconceptions log: ${misconceptions.join(', ')}`;

const response = await anthropic.messages.create({
  model: 'claude-opus-4-7',
  system: tutorSystemPrompt,
  messages: history,
  max_tokens: 400,
});
```

### xAPI 의 statement emit
```typescript
async function emitXAPI(actor, verb, object, result) {
  await fetch(`${LRS}/statements`, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'X-Experience-API-Version': '1.0.3',
      'Authorization': `Basic ${LRS_AUTH}`,
    },
    body: JSON.stringify({
      actor: { account: { homePage: APP, name: actor.id } },
      verb: { id: `http://adlnet.gov/expapi/verbs/${verb}`, display: { 'en-US': verb } },
      object: { id: `${APP}/activities/${object.id}` },
      result: { score: { scaled: result.score }, completion: result.completed },
      timestamp: new Date().toISOString(),
    }),
  });
}
```

### Open Badges 3.0 (verifiable credential)
```json
{
  "@context": ["https://www.w3.org/ns/credentials/v2",
               "https://purl.imsglobal.org/spec/ob/v3p0/context-3.0.3.json"],
  "type": ["VerifiableCredential", "OpenBadgeCredential"],
  "issuer": {"id": "did:web:acme.edu", "name": "Acme Academy"},
  "issuanceDate": "2026-05-10T12:00:00Z",
  "credentialSubject": {
    "id": "did:example:learner123",
    "type": ["AchievementSubject"],
    "achievement": {
      "id": "https://acme.edu/badges/python-mastery",
      "name": "Python Mastery",
      "criteria": {"narrative": "Complete 5 projects + final exam ≥80%"}
    }
  },
  "proof": {"type": "Ed25519Signature2020", "...": "..."}
}
```

### Knowledge graph 의 skill prerequisite
```cypher
MATCH (target:Skill {name: 'Calculus I'})
      -[:REQUIRES*1..]->(pre:Skill)
WITH collect(DISTINCT pre) AS prereqs, target
MATCH (learner:User {id: $userId})-[:MASTERED]->(s:Skill)
WITH prereqs, target, collect(s) AS mastered
RETURN target,
       [p IN prereqs WHERE NOT p IN mastered] AS gap;
```

## 매 결정 기준
| 상황 | Approach |
|---|---|
| K-12 math/reading | Adaptive engine + AI tutor (Socratic) |
| Higher-ed CS | Project-based + auto-grader + AI TA |
| Corporate L&D | Skill graph + micro-credential + xAPI |
| Language learning | Conversational AI + spaced repetition |
| Niche bootcamp | Cohort + mentor + portfolio review |

**기본값**: AI tutor (Socratic) + adaptive engine + xAPI tracking + Open Badges credential.

## 🔗 Graph
- 부모: [[Education Technology]]
- 변형: [[LMS]]
- 응용: [[Adaptive Learning]]

## 🤖 LLM 활용
**언제**: Socratic tutor, content scaffolding generation, formative feedback.
**언제 X**: high-stakes summative grading 의 LLM 의 sole arbiter 의 X.

## ❌ 안티패턴
- **Engagement-only metric**: time-on-app maximization 의 learning outcome 무관.
- **AI 의 give answer**: tutor 의 cheating tool 의 변질.
- **No interoperability**: LTI/xAPI 의 ignore — institution 의 lock-in.
- **Privacy 무시**: FERPA/COPPA 의 minor 의 consent 의 fail.
- **Credential inflation**: badge 의 rigor 의 X — recognition 의 erode.

## 🧪 검증 / 중복
- Verified (HolonIQ Edtech Funding Report 2025, IMS Global LTI/Caliper specs, Open Badges 3.0).
- 신뢰도 B (industry trends 의 변동 빠름).
