- Here is one whole pizza. Let us split it into equal shares.
- Two equal pieces make the whole pizza. One of those two pieces is one half.
- Now split the same whole into four equal pieces. One of those four pieces is one quarter.
- Select two quarters. Together they cover the same amount as one half. Two fourths equals one half.
- Your turn. How many quarters make one whole pizza? Pause and explain how you know.

Need human help?
Want extra human support?
The AI tutor works independently. If you want a person to help with a persistent gap or learning plan, you can request human tutoring separately.
The learning approach
Understanding grows through practice and correction.
Inspired by Benjamin Bloom’s mastery-learning research: find the gap, work on it, and check what the learner can do independently.
- Find the starting point
Begin with a small prerequisite question and an attempt.
- Teach one useful idea
Use a clear explanation, a worked example, and a targeted hint.
- Repair and check
Correct missed quiz answers. Fresh questions help distinguish understanding from remembering an answer.
- Return and remember
Save the lesson, revisit it tomorrow without notes, and bring persistent gaps to a human tutor.
How Bloom’s 2 Sigma Problem informs our design
Bloom’s 1984 paper reported an average advantage of about two standard deviations for tutoring combined with formative checks and corrective work in the studies described. That historical result is not a measured NovaSprout outcome or a guarantee for every learner.
We use it as a design challenge. First-try answers, corrections, and later independent performance are different signals. NovaSprout has not demonstrated a two-sigma gain; that would require a controlled evaluation of unaided learning and retention.
