Overview

MathKata helps learners build durable math skills through mastery‑based practice. It adapts difficulty using spaced repetition, provides targeted hints and explanations, and tracks progress to keep learners in the sweet spot between challenge and confidence.

Key Features

• Spaced Repetition: Systematically resurfaces problems to reinforce memory and mastery.
• Adaptive Difficulty: Adjusts question difficulty based on performance and time‑to‑answer.
• Smart Hints: Stepwise hints and explanations to nudge, not spoil, problem solving.
• Mastery Tracking: Topic proficiency and streaks that keep motivation high.

Technologies Used

• Scheduling Engine: Leitner/SM‑2‑style spaced repetition scheduling.
• Analytics: Per‑topic accuracy, time‑to‑solve and retention metrics.
• Content Model: Structured problem templates for dynamic variant generation.

Challenges and Learnings

• Tuning the scheduler to avoid oscillation between too easy and too hard.
• Designing hints that teach strategies without giving away answers.

Outcome

• Increased retention and steady proficiency gains across tracked cohorts.
