Knowledge Explorer (KE) - 8 minutes
Theory (2 min):
- Constructivist exploration with concept mapping
- Visual knowledge structures + progressive disclosure
- Adapts complexity (novice → intermediate → advanced)
Live Demo (6 min):
- Navigate to curriculum mode: Biology → Photosynthesis
- Show interactive concept map
- Click concept to see: definition, visual, examples, practice questions
- Demo prerequisite locking/unlocking
- Show how content adapts to mastery level
Key Takeaway: Self-directed exploration with just-in-time support
Socratic Playground (SPL) - 8 minutes
Theory (2 min):
- Guided inquiry through problem-solving
- Five hint agents (conceptual, procedural, reflection, worked example, error analysis)
- Socratic questioning > telling answers
Live Demo (6 min):
- Launch SPL from photosynthesis topic
- Show authentic scenario (plant health problem)
- Demonstrate hint progression:
- Try problem without hints (productive struggle)
- Request conceptual hint (guiding question)
- Request procedural hint (next step)
- Show worked example if needed
- Demo misconception correction through EMT dialogue
Key Takeaway: Learning through scaffolded problem-solving
Scenario-Based CAT (SBCAT) - 9 minutes
Theory (2 min):
- Adaptive assessment using Item Response Theory
- Difficulty adjusts to learner (θ estimation)
- Diagnostic feedback + formative guidance
Live Demo (7 min):
- Launch SBCAT assessment
- Show adaptive difficulty:
- Answer easy question correctly → harder question
- Answer hard question incorrectly → easier question
- Demonstrate feedback (not just "wrong"—why and how to improve)
- Show final diagnostic report:
- Ability estimate (θ = 0.75, intermediate)
- Strengths identified
- Gaps for remediation
- Recommended next steps (KE topics, SPL problems)
Key Takeaway: Assessment as learning opportunity, not just measurement
Key Takeaways
- KE provides self-directed exploration with adaptive scaffolding
- SPL uses Socratic method for guided problem-solving
- SBCAT makes assessment a formative learning experience
