Time on the Work
The clearest sign of progress
Research shows that time spent doing the hard work of math practice is the single best indicator of a student's progress.
Tutors Keep Students on Task
The role of a tutor is partly to explain, but mainly to keep each student focused and on task. Attention drifts easily, and a good tutor pulls it back to the work.
That steady focus is what turns session time into real progress, because time genuinely spent working is what moves a student forward.


Most Time Spent Working
We spend the majority of every session with students actually working on real problems, not listening to long explanations.
Explanation happens when it helps, but the bulk of the time is hands-on practice, because that is where progress actually comes from.
Study Time Increases Mathematical Achievement Scores
Spitzer (2021)

This study tracked how much time students spent studying math and how they performed, and found a clear link: more time actively spent on math practice went hand in hand with higher achievement. It is a reassuring, common-sense result — the children who consistently put in the practice time are the ones who make measurable gains, which is why keeping students focused and on task matters so much.

Kraft et al. (2024)

This synthesis of many studies asked a focused question: does adding more engaged learning time actually help? The answer was yes — especially when that extra time is well-structured and students are genuinely working, not just present. The quality of the time matters as much as the quantity, which is why sessions that keep students actively engaged on real problems produce the biggest gains.
