Few would doubt that motivated students learn more effectively, but new research shows that it is important they have the right kind of motivation. The new analysis of results from the 2002 Pisa survey shows that students who enjoy maths perform better than those who are keen to learn maths because they want to get a good job. The study's author was Chiu Ming-ming, associate professor at Chinese University of Hong Kong's Faculty of Education, and data included assessment scores for just under 108,000 15-year-olds in 41 countries, conducted in 2002 as part of the OECD's most recently released Pisa survey. A 10 per cent increase in interest in maths resulted in a 1 per cent improvement in scores. This was equal to the effect on performance of an HK$11,223 increase in the annual family income. Students who were 20 per cent more interested in maths scored an average of 1.8 per cent better in the tests, while the marks of those who were 30 per cent more interested were 2.6 per cent higher.
