Replaying mathematics process telemetry

The Grid Replay System reconstructs student arithmetic attempts keystroke-by-keystroke. By converting field telemetry into visual models, the platform allows researchers to analyze student problem-solving methods and identify areas of difficulty in mathematics education.

Arithmetic playback and grid interface

The application renders a nine-by-nine interactive cell grid representing the student workspace. The playback interface provides controls to play, pause, and step through calculations. As the replay runs, the active cell highlights to show digit input, carry operations, and backspaces alongside real-time timestamps.

Telemetry parsing and conversion

The system processes telemetry from two data paths:

Live assessments: parses active student data streamed from numeracy assessments.
Offline multiplication logs: converts legacy session telemetry, reconstructing missing timestamps and translating six-by-six grid structures into the nine-by-nine format.

Error detection and insights

The statistics dashboard verifies telemetry quality by comparing final student answers against values calculated by the replay engine, flagging mismatching records. A question insights page groups attempts by operand pairs (such as specific multiplication questions), ranking them by accuracy and speed to help researchers study common mistakes.

Building a scoring quality control audit system

The Audit System is a quality control interface for student evaluations. It compares field scores against auditor and rescorer grades, tracking evaluator consistency and maintaining data hygiene across multi-round assessments.

Dual-track verification

The system operates across two separate verification tracks:

LSEP audit quality control: compares field-evaluator scores against independent audits. When discrepancies arise, a third rescorer evaluates the attempt to establish a final grade.
CSF multi-round study: tracks student progression across multiple reevaluation rounds, matching scores against task groups and experimental arms from local configurations.

Reliability metrics

The platform calculates inter-rater reliability scores for individual evaluators. It tracks the volume of audits, calculates the average score difference, and flags evaluators whose variance exceeds established margins (such as a ten percent threshold for oral reading fluency). High-disagreement rates trigger alerts, helping administrators identify training needs.

Data integration

The interface integrates with external databases and Amazon S3 storage. Users can filter audits by date, student, or completed evaluations, listen to student audio clips directly in the browser, and navigate to side-by-side comparison interfaces. A maintenance worker identifies incomplete student evaluations that have already been audited, ensuring database hygiene.

Reasonable is a high-performance, reasoning-centered AI agent service built on the modern LlamaIndex Workflows architecture.

Unlike traditional LLM wrappers that simply "get an answer," Reasonable is designed with a "Reasoning-First" philosophy. Here’s a breakdown of what makes it unique:

Core Architecture

Workflows-Native: It uses the v0.14+ LlamaIndex event-driven architecture, which allows for complex, multi-step agentic behavior (like the ReAct loop) that is far more robust than legacy sequential agents.
Chain-of-Thought (CoT) Extraction: It is specifically engineered to handle "Thinking" tokens. It identifies and streams internal reasoning processes separately from final answers, providing total transparency into how the AI arrived at a conclusion.
Ollama Integration: It is locally-optimized, currently leveraging models like Qwen 3.5 (9B) to perform heavy reasoning tasks without relying on external cloud APIs for the "brain" of the operation.

The "Socratic" Philosophy

Following our latest architectural pivot, Reasonable has transitioned from a simple "solver" into a Socratic Tutor.

The Heuristic Ladder: Instead of blurting out answers, the agent uses diagnostic tools to analyze the "shape" of a problem, then guides the user through identification, strategy, and execution.
Scaffolded Interaction: It treats tools as "Math Diagnostic Engines" that provide facts to the agent, which then uses those facts to challenge and guide the user.

Technical Stack

Backend: FastAPI with full CORS support and SSE (Server-Sent Events) streaming.
Protocol: A specialized Event Schema (pulse, reasoning, call, result, message) that allows frontends to render complex agentic thoughts and tool interactions in real-time.

In short, Reasonable is about making AI interaction more transparent, educational, and - as the name implies - driven by clear, observable reasoning.
