- Enhanced detection logic to distinguish between pure 'I don't know' and thoughtful hypotheses
- When child says 'I don't know but maybe it's temperature', now treats as substantial thinking, not ignorance
- Added detection for substantive content: hypotheses, questions, specific topics (temperature, weather)
- Updated server to provide Socratic follow-up questions for thoughtful answers instead of just validation
- Improved fallback responses to be contextually aware of specific topics mentioned
- Better handling of answers that show reasoning even when prefixed with 'I don't know'
Now 'das weis ich nicht. hat es etwas mit der temperatur zu tun?' gets proper Socratic questioning about temperature instead of generic encouragement.
- Enhanced 'I don't know' detection to include German variants (ich weiß es nicht, warum, etc.)
- When child says 'I don't know', system now directly provides Socratic guidance instead of asking for deeper exploration
- Removed redundant phrases like 'Danke, dass du deine Gedanken geteilt hast' for obvious interactions
- Improved fallback responses to be more concise and natural ('Perfekt! Lass uns das gemeinsam herausfinden.')
- Updated both chat mode and step-by-step mode to have consistent behavior
- System now automatically continues to next question for 'don't know' responses, only shows choice buttons for substantial answers
This creates a smoother, more natural learning flow without interrupting the Socratic discovery process.
- Fixed /api/explore-deeper to use OpenAI for contextual Socratic questions instead of generic random prompts
- Added proper system prompts that focus on asking single, thoughtful follow-up questions
- Updated fallback prompts to be complete, engaging questions that encourage hands-on exploration
- Fixed /api/respond-to-answer to provide ONLY encouragement without giving explanations or facts
- Clarified prompts to prevent AI from revealing answers during validation responses
- Improved Socratic teaching approach for 'Tell me more' deeper exploration
This ensures both validation responses and deeper exploration maintain pure Socratic methodology.
- Fixed the critical issue where AI was giving direct answers instead of asking guiding questions
- Now when child answers 'no' or 'don't know', system calls /api/ask for Socratic guidance
- When child gives substantial answers, system calls /api/respond-to-answer for validation
- Applied fix to both chat mode and step-by-step mode
- Enhanced answer analysis to detect negative/unknown responses vs substantial answers
- Updated response handling to work with both guidance format and simple response format
This ensures the AI acts as a true Socratic teacher, guiding discovery rather than giving answers.

PROBLEMS WITH MATH:
- AI giving wrong feedback (said 8 was correct for 2+7=9)
- Generic responses not building mathematical understanding
- No validation of correct/incorrect math answers
- Poor pedagogical approach for arithmetic
SOLUTIONS IMPLEMENTED:
✅ Mathematical Expression Detection
- Added regex to detect math expressions (+, -, ×, ÷, =)
- Special handling for arithmetic vs science questions
✅ Math Answer Validation
- Evaluates basic arithmetic (2+7, 10+5, etc.)
- Validates if child's answer matches correct result
- Provides accurate feedback for right/wrong answers
✅ Better Math Pedagogy
- Correct answers: 'Excellent! 2+7 does equal 9!'
- Incorrect answers: 'Close thinking! Let's count together...'
- Don't know: 'Let's solve this step by step using counting!'
✅ Enhanced AI Prompts
- Math context awareness in AI responses
- Focus on counting, number sense, arithmetic understanding
NOW: Math questions get proper mathematical validation and education!
IMPROVEMENTS:
🔢 Math Questions:
- Detects math questions (contains +, -, numbers, sum, total, count)
- AI responses focus on mathematical thinking and counting
- 'yes' → 'Great! Math is fun when we take it step by step.'
- Answer reveals show '🔢 Mathematical Solution' not 'Scientific Explanation'
- Button text: 'Show Solution!' instead of 'Reveal Answer!'
🔬 Science Questions:

- Proper 'Scientific Explanation' labeling for science topics
🎯 Better Fallback Responses:
- Math-specific encouragement for numbers and counting
- Subject-appropriate emojis and language
- More relevant feedback for different question types
BEFORE: '10+5' → 'Scientific Explanation' ❌
NOW: '10+5' → '🔢 Mathematical Solution' ✅
PROBLEM: Same question being asked twice instead of progressing
- Question 1 answered → AI responds → Question 1 asked again (not Question 2)
ROOT CAUSE: currentQuestionIndex not being incremented after answer
- askNextQuestion() was using same index repeatedly
SOLUTION:
- Added currentQuestionIndex++ before askNextQuestion() calls
- Fixed both success and fallback code paths
- Now properly progresses: Q1 → Answer → AI Response → Q2
FLOW NOW:
1) Fish live where? → 'in water' → AI validates → 2) Next question
NOT: 1) Fish live where? → 'in water' → AI validates → 1) Fish live where?
PROBLEM: AI was generating follow-up questions AND system was asking pre-programmed questions
RESULT: Confusing double questions like 'Now, can you think about...' + '1) Do you know...'
SOLUTION:
- Modified AI prompt to NOT include follow-up questions
- AI now only provides encouragement and validation
- System handles question flow with pre-programmed sequence
- Cleaner, less cluttered conversation experience
BEFORE: 'Great thinking! Now, what do you think happens next? 🤖 1) Do you know...'
AFTER: 'Great thinking! You understand the concept perfectly! 🤖 1) Do you know...'
