German High School Kids Can Benefit from Optional Start Times

Students attending a high school in Germany can decide whether to begin classes at the normal start time or an hour later. According to researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich, the option has had a positive effect on students’ sleep and learning experiences.

The findings are published in the journal Sleep.

Sleep deprivation among young people has become a public health issue. The consequences of chronic sleep loss include not only a reduced ability to concentrate but also an increased accident risk to and from school. Research has also shown a link between sleep deprivation and depression, obesity, diabetes and other chronic metabolic diseases.

In light of these findings, more people are calling for school classes to begin later in the morning. But would such a move do any good? Would a later school start actually change the sleep of adolescents for the better, and enhance their cognitive performance in class?

A group of chronobiologists in Munich, led by Drs. Eva Winnebeck and Till Roenneberg, studied the issue at a high school in Germany which made an exceptional change to their starting time arrangement.

The school allows students in higher grades to decide day by day whether or not to attend the first class of the day or to arrive an hour later. This form of flexible scheduling is possible because the school has adopted what is known as the Dalton Plan (for which the institution won the German School Prize in 2013).

A major component of this idea (which originated in the U.S.) is that students are required to work on parts of the school curriculum independently in the context of project phases. The school timetable allots 10 hours per week for these activities, half of which are scheduled for the first class at 8 in the morning.

Students who choose to skip this class must work through the material in their free periods during the day or after the end of the regular school day.

Students from the three senior grades (i.e. 15- to 19-year-olds) served as the study population for LMU researchers from the Institute of Medical Psychology. For 3 weeks before and 6 weeks after the introduction of the flexible system in the school in Alsdorf, the team observed how the students reacted and adapted to the change.

The students were asked to record their sleeping patterns daily, and around half of them were equipped with activity monitors for objective sleep monitoring. At the end of the study, the participants provided information on their sleep, their overall level of satisfaction and their ability to concentrate.

The team was initially surprised by the fact that the students made relatively little use of the new-found freedom to start school later, Winnebeck said. On average, they chose to miss out on the first class twice a week. On these days, they slept more than an hour longer than usual, irrespective of gender, grade, chronotype or frequency of later school starts. In other words, nearly all of the students involved in the project benefited when going later.

In contrast to the era of rigid school start times, however, the switch to flexible starts did not result in a significant increase in the overall duration of students’ sleep. Nevertheless, the students were very satisfied with the new scheduling model. The vast majority of students reported that they slept better and were better able to focus on the course material in school.

“Perhaps the very fact that one can decide for oneself when to get up in the morning is sufficient to break the cycle and reduce the pressure,” Winnebeck said.

According to the authors of the study, “flexible systems are a viable alternative for implementing later school starts to improve teenage sleep.” But they also underline the importance of actively encouraging students to make use of the option to start the school day later.
