Language school problems
- Constant practice: language learned with daily repetition, not 2x weekly classes
- Difficult listening: students watch video without pausing, don't internalize
- Vocabulary memorize-forget: without SRS, words leave memory in days
- Scarce conversation: few opportunities to practice outside class
- Variable engagement: Duolingo creates addicts, traditional schools don't
- Subjective evaluation: essays/oral corrected manually, slow
How Studeia solves
1. Interactive video (listening + comprehension)
Lesson subtype interactive_video with checkpoints (mandatory pauses). Student cannot advance without answering each checkpoint. Forces attention + active processing.
2. Flashcards with SRS (vocabulary)
Lesson subtype flashcard_set with modified SM-2 algorithm. Student rates: easy/good/hard/again. System schedules next review (14d, 7d, 1d, 0d). Studeia stores StudentFlashcardReview with nextReviewAt. Notifies student when cards are due.
Cards can have embedded audio (pronunciation). Syncs in mobile app for offline review.
3. Live classes (conversation)
- Zoom: best for large schools (1000 participants, automatic recording)
- BBB: open-source for self-hosted
- Teams: for Microsoft 365 schools
- Google Meet: for Google Workspace schools
Features: automatic recording, VTT transcript ingested in RAG, breakout rooms.
4. Gamification for daily streak
XP Rules configured via Gamification Agent:
- dailyLogin: 5 XP
- lessonComplete: 30 XP
- flashcardReviewSession (>= 20 cards): 25 XP
- liveClassJoin: 50 XP
Streak bonus: 7d=+100 XP, 30d=+500 XP, 100d=+2000 XP "Centurion", 365d=+10000 XP "Annual Dedication".
Class-scoped leaderboard, weekly window — healthy competition.
5. AI tutor for questions
PedagogicalAgent adapts:
- Beginner (CEFR A1-A2):
direct_instructionpredominant - Intermediate (B1-B2):
scaffolding+socratic - Advanced (C1-C2):
challenge
Tutor responds in target language. RAG ingests school's own material.
6. LLM essay evaluation (optional)
For essay-type questions: admin enables LLM grading (~$0.01-0.05 per correction). Sonnet evaluates per configured rubric (grammar + cohesion + vocabulary + content). Reduces correction time by 70-80%.
