It found computer use in the classroom had mixed effects on student performance. Most notably, students who frequently used computers didn't test well in reading.
The use of computers every day was even found to hinder digital reading comprehension.
Based on the findings, it seems students who used computers less than average, tested the highest in both print and online reading comprehension.

In this picture taken on June 30, 2010, Pakistani Baluch women take a computer training class at the Baluchistan Institute of Technical Education (BITE) run by the Pakistan army in Quetta. The army founded the Baluchistan Institute of Technical Education (BITE) three years ago in Quetta as part of a pilot programme to turn raw youth into skilled labour in the resource-rich, but insurgency-torn southwestern province. Although a drop in the ocean of massive challenges facing Baluchistan's eight million people, the institute offers an opportunity for teenagers from low-income families to learn skills that can earn them a decent livelihood. Baluchistan has some of the most remote communities in Pakistan, miserable social indicators and a deeply traditional society where many women, particularly in the countryside, are rarely allowed to leave the home. Baluchistan, which borders Afghanistan and Iran, has suffered from a separatist insurgency for six years. Sectarian killings targeting non-Baluch and non-Sunni Muslims are on the rise in Quetta, the regional capital. (Photo credit AAMIR QURESHI/AFP/Getty Images)

A writer for The Washington Post summed it up nicely: "The time kids are spending getting acquainted with computers is time they aren't spending honing their reading skills."
And using computers to teach students math also seemed to ding their scores in that area.
This OECD report comes after years of teachers and administrators promoting technology in the classroom, including a teacher in Maryland who found it helped boost AP calculus test scores for her students, compared with the previous year when her lessons didn't use technology.
But OECD's findings might have more to do with how students use their computers.
The Wall Street Journal spoke with a director at the State Educational Technology Directors Association who said technology in the classroom won't have much of an effect on education if students don't know how to properly use that tech.
OECD did say schools should train teachers how to use technology in the classroom so they can pass on that knowledge to their students.
