Notably, research by Susanna Loeb (Stanford University) revealed that tutoring methods and strategies can vary dramatically both in their design features and student outcomes. Loeb’s team of researchers discovered that in particular “high impact” tutoring strategies have demonstrated statistically significant effects on student learning in math and reading. High impact tutoring contains the following features:
- One-on-one tutoring (or with very small groups)
- Tutoring content is aligned with in-class instruction
- Students receive tutoring at least three times per week from the same tutor
- Tutors are professionally trained
