PARIS: Asian countries dominated the top places in a key survey released Tuesday of high-school skills, but the report criticised science teaching in many countries.
The PISA survey of 15-year-olds in 72 countries and economies found that the quality of science lessons was more important than the equipment or even staffing levels.
And it confirmed earlier findings that burdening students with homework or extra tuition was rarely the key to success in science.
Singapore came top of the table for its teaching of science, reading and mathematics.
Singapore’s students scored an average of 556 points, compared with the average among Organisation for Economic Co-operation and Development (OECD) countries of 493.
Where once Finland led the way in educational excellence, Singapore is now the example to other countries, the report said.
“Singapore is a standout performer,” said OECD Secretary-General Angel Gurria at the global launch of the report in London.
“In Singapore, one in five students master the most advanced scientific problems and demonstrate that they think like scientists.”
Nearly a quarter of all students in Singapore (24 percent) scored in the top two categories in science tests, compared with just eight percent across the OECD countries.
The five top-performing countries in the PISA tests, which were carried out in 2015, were Singapore, Japan, Finland, Estonia and Taiwan.
However the report found that only 12 countries assessed had improved their performance in science since 2006, despite an increase in spending per primary and secondary student of 20 percent over the same period.
“A decade of scientific breakthroughs has failed to translate into breakthroughs in science performance in schools,” said Gurria, adding that science education “isn’t keeping up” with the “lightning speed” of scientific progress.
Around six percent of students in OECD countries, many of them in Europe, reported they did not get regular science lessons. These students scored significantly lower in the tests.
Schools where dedicated science lessons weren’t offered tend to be in poorer areas of countries, the report noted. The problem was particularly bad in Austria, Belgium, Croatia, France, Germany, Slovakia and Taiwan.
The results also suggested that the key to success in science teaching, even more than well-equipped and well-staffed departments was how much time was spent teaching the subject.
Those teachers who actually demonstrated scientific ideas and who adapted their teaching to meet students’ needs produced better results, the report said.
That tended to happen in smaller classes, and students who received this kind of teaching were more likely to go on to a science-related career, it added.
“It’s not about science tests, it’s about engaging students and making science learning relevant… that’s what translates to better outcomes and better careers,” said Andreas Schleicher, the OECD’s director for education and skills, at the London launch.
The report also suggested that the study of science needed to be done in school, not at home.
“School systems where students spend more time learning after school, by doing homework, receiving additional instruction or in private study, tend to perform less well in science,” the report said.
Last month, parents in Spain staged a strike to protest the amount of homework schools were handing out. Spain scored 493 points in the latest PISA tests corresponding exactly to the OECD average.
Asian countries dominated the top 10 of the PISA table; with Japan recording the second-highest average score behind Singapore.
