The Most Powerful Teaching Tool Schools Underuse

One to one tutoring is not a luxury. It is the missing operating system.

Business schools love talking about personalized education. Then they put 55 students in a room, give them a slide deck, a group project, three deadlines, and call it transformation. Cute.

The dirty little secret is that some of the most powerful teaching does not happen during the lecture. It happens in the one to one moment. The ten minute conversation where a student finally admits they are lost. The project coaching where a team stops hiding behind pretty words and understands what their idea actually is. The quiet intervention before a weak student disappears, cheats, fails, or mentally checks out.

Research has been circling this for decades. Bloom’s famous “2 sigma problem” argued that one to one tutoring can produce dramatically better learning outcomes than conventional classroom instruction. The debate around the exact effect is real, and fair. But the direction is not mysterious: good tutoring works. Very well.

I’ve tested this in small doses during my own teaching. It reduces attrition. It improves projects. It flattens lazy AI usage because students must explain their own logic. It improves participation because students feel seen before they are judged. It also protects the school and the professor from the usual anonymous drive by shooting called “end of course feedback.”

Here’s my proposal: every serious 8 to 12 session business school course should include structured one to one tutoring slots. Not optional office hours buried in a syllabus. Real tutoring, designed into the course.

But here is the uncomfortable part: you cannot industrialize this with warm bodies and a calendar invite. The tutor matters. Talent matters. Energy matters. Care matters.

Which is exactly why schools should stop treating it like a bonus. Because it’s the product.
