Turns out, college students study best later in the day

Students learn more effectively between 11 a.m. and 9

The research used two new approaches to determine ranges of start times that optimize functioning for undergraduate students. Based on a sample of first and second year university students, the University of Nevada, Reno and The Open University in the United Kingdom used a survey-based, empirical model and a neuroscience-based, theoretical model to analyse the learning patterns of each student to determine optimum times when cognitive performance can be expected to be at its peak.

"The basic thrust is that the best times of day for learning for college-age students are later than standard class hours begin," co-author Mariah Evans said. "Especially for freshmen and sophomores, we should be running more afternoon and evening classes as part of the standard curriculum."

The analysis assessed the preferred sleeping times of the participants and asked them to rate their fitness for cognitive activities in each hour of the 24-hour day.

"Neuroscientists have documented the time shift using biological data - on average, teens' biologically 'natural' day begins about two hours later than is optimal for prime age adults," Evans noted. "The survey we present here support that for college students, but they also show that when it comes to optimal performance, no one time fits all."

The study showed that much later starting times of after 11 a.m. or noon, result in the best learning. It also revealed that those who saw themselves as "evening" people outnumbered the "morning" people by 2:1, and it concluded that every start time disadvantages one or more of the chronotypes (propensity for the individual to be alert and cognitively active at a particular time during a 24-hour period).

"Thus, the science supports recent moves by the University to encourage evening classes as part of the standard undergraduate curriculum," Evans said. "It also supports increasing the availability of asynchronous online classes to enable students to align their academic work times with their optimal learning times."
