MAST: Multi-dimensional Adaptive Skill Tracing — A Domain-Agnostic Framework for Evidence-Restricted Adaptive Learning
We introduce MAST (Multi-dimensional Adaptive Skill Tracing), a domain-agnostic adaptive learning framework that extends Bayesian Knowledge Tracing into multi-dimensional skill domains governed by differential decay and evidence restriction. MAST makes four contributions: a forma…

Time to Fluency: A Research-Calibrated Model for Personalised Language Program Duration
Every language learning platform that has ever told you "reach fluency in 3 months" applied the same timeline to every learner, regardless of their native language, starting level, or target language. A French speaker learning Spanish and a French speaker learning Mandarin are no…

Checkpoint Reassessment as Low-Stakes Motivation: Day 30/60/90 Progression
Single-shot language assessments create high-stakes anxiety. A learner completes an intensive course and faces one final test: pass, and they have "proven" their proficiency; fail, and months of effort feel wasted. This binary outcome structure reduces intrinsic motivation and…

Computed Commitment Pricing: A Research-Derived Pricing Model for Outcome-Oriented Language Training
The dominant pricing model in language-learning technology — tiered subscription menus — decouples cost from outcome. A learner pays the same monthly rate whether they are six months from B1 or three years away; whether they study Swahili or Spanish; whether they commit one hour …

The Multidimensional Progress Hypothesis: Why Single-Score Systems Fail Learners and What Honest Measurement Looks Like
Every major educational technology product today collapses multidimensional competence into a single score. That score is not a measure of learning — it is a measure of attendance. It rewards consistency over capability, optimises for engagement over mastery, and systematically m…

Beyond XP: A Performance-Gated Progress Architecture for Language Acquisition
Most gamified language applications reward engagement rather than acquisition, using experience-point (XP) systems that award identical points for correct and incorrect responses. This paper presents Fluency Points (FP) — a multi-dimensional, performance-gated progress metric cal…
