See every trial. Trust every decision.
Six clinical-grade visualizations turn raw trial data into the insight every instructor, supervisor, and family needs. Real-time, bilingual, and exportable.
Accuracy Trend by Session
Per-session accuracy with a 5-session moving average overlay. Threshold-colored dots and an 80% mastery reference line so you spot trends in a glance. Phase-change vertical lines mark errorless transitions.
Cumulative Record
The cumulative graph every instructor learns to read. Total correct responses over time — slope reveals the learning rate, flat segments expose stalled progress. The chart your supervisor expects to see.
Response Time Distribution
Seven latency bins from <300ms guesses to >15s disengagement. The engine flags fast-guessing and slow-disengagement automatically and adjusts errorless phases — most competitors don't track timing at all.
Error Pattern Radar
Real-time detection of five clinically-significant error patterns: position bias, perseveration, overselectivity, fast guessing, slow disengagement. When a pattern crosses threshold, the engine adjusts the next session. Unique to Interlaza.
Concept Mastery Grid
A heatmap of every concept across every level — Identity, Non-Identical, Symbolic, Auditory. Hover any cell for accuracy, trial count, and status. The fastest way to spot a stalled concept across a learner's entire library.
Live Accuracy — Real-Time Supervision
During a supervised session, accuracy updates trial by trial. The supervisor sees fatigue, drift, and breakthroughs as they happen — not after the session ends. Built on Supabase Realtime, ~3 second latency.
Tap Pad — Instructor Data Entry
For sessions run by an instructor on a tablet, Tap Pad captures every trial in one tap: independent, prompted, incorrect, or no-response. Latency is recorded automatically. The instructor never has to look away from the learner.
Group Insights — The Whole Caseload at a Glance
One dashboard for every learner you support. See average accuracy, how the group splits across mastery bands, sessions over time, and exactly who needs attention right now — filtered by class and time range. Built for instructors managing 25 to 100 students.
Roster Control Center — Triage at Scale
A scannable roster with the signals that matter: sessions, accuracy (colour-coded), and last-active, all sortable. One-click views — Active this week, Needs attention, Not started — surface the learners who need you, without scrolling through cards.
What sets Interlaza apart
Response-time analytics
Most competitors don't track latency at all. Interlaza bins it 7 ways and flags both extremes.
Real-time error pattern detection
Five clinically-validated patterns surfaced as a radar chart, with the engine auto-adjusting downstream.
BKT-driven adaptive difficulty
Bayesian Knowledge Tracing surfaces P(mastery) per concept and adjusts trial composition automatically.
Live supervision per-trial
Supervisors can watch a remote session update trial-by-trial via Supabase Realtime — ~3s latency.
Tamper-evident trial data
Every trial log is sealed with a SHA-256 hash chained to the previous one. Editing any past trial breaks the chain — verifiable by anyone, not just us. The data you publish, defend, or bill against is provably untouched.
