In an experiment involving 62 undergraduate students taking a principles of accounting course, half of the cohort was allowed to text during a lecture and half had their phones turned off. After the lecture both groups took the same quiz and the students who did not text scored significantly higher on the quiz.
Students who tried to listen to the lecture while using these distractive windows had significantly lower scores on homework, projects, quizzes, final exams and final course averages than students who looked at mostly productive windows. Researchers also found that this population under reported the extent of their multitasking.
The group that used instant messaging while they read took between 22 and 59% longer to read the passage than students in the other two groups and that was after the time spent instant messaging was subtracted from the reading times.
From the iTunes U app, students can play video or audio lectures and take notes that are synchronized with the lecture. They can read books and view presentations. See a list of all the assignments for the course and check them off as they’re completed. And when you send a message or create a new assignment, students receive a push notification with the new information.1
