Oral Assessment, Designed With Educators
Move beyond multiple-choice. CALLIOPE (Conversational Assessment for Learning, Listening & Intelligent Oral Performance Evaluation) supports spoken dialogue, source-grounded probing, six-dimensional draft evaluation, and educator review in one pilot workflow.
Advanced Platform Architecture
A responsive prototype for designing, conducting, and reviewing conversational assessments.
Multi-Source Context Engine
Add public web pages or plain-text files. CALLIOPE uses the extracted material as approved context for questions and draft evaluation; educators remain responsible for checking accuracy.
Real-Time Turn-Taking
Powered by local WebAudio VAD. Calliope listens, waits for the student to finish their thought, and responds conversationally without requiring UI clicks.
Six-Dimensional Evaluation
After a session, configured AI evaluators produce draft evidence across six dimensions for educator review and adjustment.
1. Content Accuracy
Estimates factual correctness against educator-provided source material, with the result presented as a reviewable draft.
2. Explanatory Depth
Measures comprehension beyond rote memorization by extracting causal reasoning chains directly from spoken transcripts.
3. Scientific Reasoning
Reviews Claims-Evidence-Reasoning (CER) structure, falsifiability awareness, and possible logical gaps after the session.
4. Systems Thinking
Analyzes semantic breadth across domains and the student's ability to articulate complex feedback loops and emergent behaviors.
5. Communication Clarity
Evaluates logical cohesion, pacing (Words Per Minute), and filler word frequency to ensure effective articulation.
6. Metacognitive Awareness
Reviews observable self-correction, stated uncertainty, and strategy reflection as evidence of metacognitive monitoring; it does not infer a learner's internal confidence.
Built for Educators
Prototype tools for creating learner-specific sessions, reviewing transcripts, adjusting AI draft scores, and publishing feedback.
Intuitive Builder
Assign a session to a learner, configure its duration and opening prompt, attach source material, and set rubric weights.
Actionable Analytics
View aggregate classroom performance charts or drill down into individual student transcripts to identify systemic knowledge gaps.
Role Management
Secure Role-Based Access Control (RBAC) ensures students only see their own assessments while educators maintain full oversight.
