Study: Smartphones May Be Lowering Exam Grades

A study in Educational Psychology has found that US university students who copy homework answers get better grades on their homework, but worse grades on exams compared to those who answer homework questions from memory or by guessing. And smartphones may be making the problem worse.

The study followed 2,433 students taking 12 different university classes over 11 years. It showed that students who did better on their homework than on their exams were more likely to use Google, check their textbook, or talk to a friend who already had the answer when completing their homework.

These students' exam results were several percentage points below those of students who did their homework from memory.

The number of students doing better on their homework than on exams has also increased from 14% in 2008 to 55% in 2017. During that time, smartphones have become ubiquitous: the first iPhone was released in June 2007, and according to the Pew Research Center, by January 2018, 77% of US adults had a smartphone.

Writing in NJ.com, Arnold Glass, the study's lead author, said that smartphones make it "remarkably easy" to look up homework answers. He also said that smartphones make it harder to pay attention to homework, since students may also be using them to chat with friends or play games, which affects how well they remember what they learn.

Glass said that students are less likely to remember an answer if it did not come from their own mind. He said that students should always try to come up with an answer on their own, even if they guess or get it wrong.

"If the student does this first and then finds the correct answer online, the student is likely to remember the answer," he said — and this will help them do better on exams.
