Analysed 2 years of student interaction data to identify the 12 strongest predictors of learning outcome and dropout risk.
Built a knowledge graph of 8,000 learning objectives with prerequisite relationships, enabling the engine to identify and fill knowledge gaps.
Developed a content difficulty adjustment algorithm that modifies question complexity in real-time based on the student's recent performance trajectory.
Implemented a parent dashboard showing weekly learning progress, time-on-task, and personalised recommendations for at-home practice.
Ran an 8-week A/B test comparing adaptive vs. linear learning paths — 34% better learning outcomes confirmed before full rollout.
Built an adaptive learning engine that adjusts content difficulty, pacing, and format based on individual student performance data.
