Spending just one hour per day on Maths and Science could help kids produce better results, according to a latest research. Researchers from the University of Oviedo in Spain looked at the performance of 7,725 public, state-subsidised and private school students in the principality of Asturias in northern Spain. The researchers found that the students spent on average between one and two hours a day doing homework in all subjects. Students whose teacher systematically assigned homework scored nearly 50 points higher on the standardised test. Students who did their math homework on their own scored 54 points higher than those who asked for frequent or constant help. The curves were similar in science. "Our data indicate that it is not necessary to assign huge quantities of homework, but it is important that assignment is systematic and regular, with the aim of instilling work habits and promoting autonomous, self-regulated learning," said Javier Suarez-Alvarez, graduate student, co-lead author with Ruben Fernandez-Alonso, PhD, and Professor Jose Muniz. The data suggest that spending 60 minutes a day doing homework is a reasonable and effective time. The total amount of homework assigned by teachers was a little more than 70 minutes per day on average, the researchers found. As for working autonomously or with help, the researchers found that students who needed help and did 70 minutes of homework per day could expect to score in the 50th percentile on their test while autonomous students spending the same amount of homework time could expect to score in the 70th percentile One possible explanation of this result is that self-regulated learning is strongly connected to academic performance and success, according to Suarez-Alvarez. The students had a mean age of 13.78. Girls made up 47.2 per cent of the sample. The article was published in American Psychological Association's Journal of Educational Psychology. The students were given questionnaires asking how often they did homework and how much time they spent on various subjects. They were also asked whether they did their homework alone or whether they had help and, if so, how often. Their academic performance in math and science was measured using a standardised test. Adjustments were made to account for gender and socioeconomic background. Prior knowledge was measured using previous grades in math and science.
