Study: Banning Smartphones From Classrooms Boosts Test Scores

Researchers found banning smartphones from the classroom helped raise the worst students' test scores and bring up the class average.

Smartphones divide our attention, distracting us at the dining table, during events, and on the playground. By 2012, it was reported that 90.3 percent of English teens owned a mobile phone and 73 percent of U.S. kids had one of their own as well. However, schools have been struggling to keep them out of classrooms well before then — since Zack Morris first started taking calls in class on his brick cellphone back in the '90s. So, just how much are kids studies suffering from such technological distractions?


Richard Murphy and Louis-Philippe Beland, both assistant professors of economics, sought to find the answer. They measured the impact of mobile phones on student exam performance from 2001 to 2013 by surveying 91 English schools in the cities of Birmingham, London, Leicester, and Manchester before and after strict cellphone policies were enacted.

Murphy said in a press release:

"We found the impact of banning phones for these students equivalent to an additional hour a week in school, or to increasing the school year by five days."

They found that the lowest-achieving students tended to benefit most from the policy, increasing their test scores by 14.23 percentage points of a standard deviation. Whereas the average class would increase their test scores by 6.41 percentage points of a standard deviation. However, the ban provided little benefit for the school's highest-achieving individuals.

Murphy explained:

"This means allowing phones into schools would be the most damaging to low-achieving and low-income students, exacerbating any existing learning inequalities. Whilst we cannot test the reason why directly, it is indicative that these students are distracted by the presence of phones, and high-ability students are able to concentrate."

The researchers suggest this could be one of the most cost-efficient methods of reducing education inequality. However, the researchers do not discount smartphones as a effective learning tool, but only “if their use is properly structured.”

The world and workforce need wisdom. Why don’t universities teach it?

Universities claim to prepare students for the world. How many actually do it?

  • Many university mission statements do not live up to their promise, writes Ben Nelson, founder of Minerva, a university designed to develop intellect over content memorization.
  • The core competencies that students need for success—critical thinking, communication, problem solving, and cross-cultural understanding, for example—should be intentionally taught, not left to chance.
  • These competencies can be summed up with one word: wisdom. True wisdom is the ability to apply one's knowledge appropriately when faced with novel situations.

Six-month-olds recognize (and like) when they’re being imitated

A new study may help us better understand how children build social cognition through caregiver interaction.

Personal Growth
  • Scientists speculate imitation helps develop social cognition in babies.
  • A new study out of Lund University shows that six-month-olds look and smile more at imitating adults.
  • Researchers hope the data will spur future studies to discover what role caregiver imitation plays in social cognition development.
