Built on the research
The design is built on peer-reviewed studies and national practice guides. Where the evidence is thin, or a number is a starting value still to be tuned, the plan says so. The reviews set it out:
- How 9-year-olds become fluent in math facts, and how to practice without inducing math anxiety
- Teaching math concepts to 9-year-olds with visual models, animation, and explanation: an evidence review
- Making a math app fun for a 9-year-old: a literature review
- Adaptive learning, mastery, knowledge tracing, and feedback for a solo-built math app (age 9)
- Competitive landscape: math learning apps for ages 8 to 11 (grades 3 to 5)
- Attention, ADHD, and math practice: what the evidence says for a fluency and learning app
- General learning science for Numberkit (how people learn and remember, beyond games and apps)
- How people learn mathematics: evidence from cognition and classrooms, and what an app can take from it
- Effective human teaching and tutoring, and what an app can take from it
- Motivation, emotion, and habits in learning mathematics
- Calibrating and evaluating Numberkit with very few learners
- Clinical cognitive-training platforms and gaming in children's neurorehabilitation
- Adaptive placement with a handful of questions
