How can tutors reach more kids? Researchers look to ed tech paired with human tutors

One of the few replicated findings in education research is that daily, individualized tutoring during the school day really helps kids catch up academically. The problem is that this kind of frequent tutoring is very expensive and it’s impossible to hire enough tutors for the millions of American public school students who need help.

Studies have shown that computerized tutoring systems, where algorithms guide students through lessons tailored to their individual needs, can be effective when kids use them. But kids are tired of learning over screens and the kids who are the most behind at school are the least likely to have the motivation to learn independently this way.
What if you were to marry humans with technology? Could you substitute some of the tutoring time with time on ed tech without sacrificing how much students learn? That’s exactly what a team of University of Chicago researchers tried with 1,000 students ..
