Recent research in education has actually explored the question. The Center for American Progress published a summary of research findings [1] in January that noted: "High-dosage tutoring is one of the few school-based interventions with demonstrated significant positive effects on both math and reading achievement," so it's a viable solution—if there's funding. The limitation is price. Many listings for reputable math tutors are greater than $60 USD per hour. If you go by the CAP's minimum for "high-dosage tutoring" of a 30-minute session three times a week, that sums to at least $360 USD per month. Many parents do pay for this for children, but it's an unaffordable expense for many people. There is an initiative to provide free tutoring (via the "Schoolhouse" project founded by Khan Academy's Sal Khan to have volunteer tutors, who are often university students), but it's not yet clear to me whether the quality of volunteer tutors will be sufficient to make a difference in the success of students. I've also read elsewhere that one of the most important factors in tutoring effectiveness is the frequency of consistently meeting with the tutor. An AI tutor would help with frequency via lowering the price—though then again, there may be more feelings of accountability with meeting a human person at a scheduled time, versus using a software tool consistently.
