Do equations and historical( 歷史的) facts give you a headache? A change in the school timetable

(課程表) may be the cure.

This suggestion is based on a recent study carried out by scientists from Royal Holloway, University of London, the UK. They found that teenagers could get higher marks in math if they studied in the mornings and better grades in history if they were taught in the afternoons.

The researchers studied students’ grade reports, class timetables and absence rates( 缺席率) at a

middle school in Bulgaria over nine years. The results showed that when teenagers had math classes earlier in the day, they scored about 7 percent higher in tests than when taught in the afternoon. Lower-ability students feel stressed most when they were studying math in the afternoon. In history, students taught in the afternoon scored about 6 percent higher than when they were taught in the

morning. However, there was no sign that similar patterns( 模 式 ) work for other subjects such as

languages or geography.

Velichka Dimitrova, who did the study, said the findings show that we perform( 表 現(xiàn) ) better at

different times of the day. “In the morning, our brains are better and fresher, so we are better at doing something like problem solving, where we require more speed and attention” Dimitrova told The Telegraph. “In the afternoon, it seems that this process slows down. On the other hand, history is more suitable for the afternoon, when we are more creative and open to discussion,” she said. Subjects such as foreign languages require both memory and creativity. This is perhaps why the time of day had no influence on language learning.

Time-of-day influences such as these are believed to have something to do with the body clock.

This is the system in our bodies that controls when we need to sleep. Some schools in the US and UK have tried later school starting times for teenagers, whose body clocks change as they grow into adults. Dimitrova believes schools should jump at this chance to improve their students’ performance just by changing their timetables.
