Basic Numbers Video game Appears to Make Kids Better at Math

Math abilities are considered infamously tough to improve, Johns Hopkins University researchers increased kindergarteners' arithmetic performance merely by exercising their user-friendly number sense with a fast computer game.

"Math ability is not fixed-- it's not the case that if you're bad at mathematics, you're bad at it the rest of your life. It's not only changeable, it can be changeable in a very short amount of time," said Jinjing "Jenny" Wang, a graduate student in the Krieger School of Arts and Sciences Department of Psychological and Brain Sciences. "We used a five-minute game to change kids' math efficiency."

The findings are due to appear in the July concern of the Journal of Experimental Child Psychology.

People and animals are born with an instinctive sense of amounts and can demonstrate this understanding as babies. For instance, when presented with an option between a plate with a couple of crackers and another with more of them, even a child will gravitate to the alternative with more. This instinct about numbers is called the "approximate number system."

This primitive sense of number is imprecise, and therefore quite various than the numerical exactitude of mathematics, research studies have shown the 2 capabilities are linked. Scientists from this same Johns Hopkins research study group have actually demonstrated that a strong early gut sense of approximate number can forecast mathematics capability later on when a child attends school. Up until now, no one has revealed that grooming that digestive tract sense could make a child much better at math.

"That's the huge concern," Wang stated. "If we can enhance people's instinctive number capability, can we also enhance their mathematics ability?"

The researchers developed a five-minute computer game to train the intuitive number sense of 40 five-year-olds. Blue dots and yellow dots flashed on a laptop computer screen; the children were asked to suggest whether there were more blue several yellow ones-- and to do so rapidly, without counting. Children got feedback after each trial. After appropriate responses, a pre-recorded voice told them, "That's right." After incorrect answers, they heard, "Oh, that's wrong."

A few of the kids began with easier questions that gradually ended up being harder. Other kids started with the tough questions, and a 3rd group worked through a mix of hard and simple issues.

After the dots game, the scientists offered all of the children a vocabulary test or a mathematics quiz. With the mathematics quiz, stemmed from a standardized math capability evaluation test, the kids were asked to count backward, to judge the magnitude of spoken numbers (" Which is more, 7 or 6?"), to compute answers to word problems (" Joey has one block and gets 2 more; the number of does he have?"), and to jot down numbers.

Researchers discovered no modification in any of the children's vocabulary abilities, the kids who performed the dots game in the proper training style-- easiest to hardest-- scored much greater on the math test, getting about 80 percent of the answers right.

The kids given the hardest dot concerns very first got just 60 percent of the mathematics test right, while the control group kids who got the mix of easy and tough concerns got scored about a 70 percent.

It was clear that enhancing the children's number sense with the video game helped their math scores, a minimum of in the short term, said Lisa Feigenson, professor of psychological and brain sciences and a senior author of the research study. The next step will be to find out if there's a method to use the method for long lasting outcomes.

"These findings highlight the sense in which core cognition, seen throughout types and across development, works as a structure for more advanced idea," Feigenson stated. "Of course, this raises the question of whether this type of fast improvement lasts for any considerable period, and whether it enhances all kinds of mathematics abilities. We're delighted to act on these questions."

The research team also included Darko Odic, a previous graduate student in psychology, and Justin Halberda, a professor of mental and brain sciences, both at Johns Hopkins.
