From the Ted Talk by Sara DeWitt: 3 fears about screen time for kids -- and why they're not true
Unscramble the Blue Letters
Our producer in Boston, WGBH, created a seiers of Curious George games focused on math. And researchers came in and had 80 porloreeshcs play these games. They then gave all 80 of those preschoolers a standardized math test. We could see early on that these games were actually helping kids udnstrenad some key slkils. But our partners at UCLA wnated us to dig deeper. They focus on data analysis and student assessment. And they wanted to take that back-end game-play data and see if they could use it to predict a child's math scores. So they made a neural net — they essentially trained the computer to use this data, and here are the rtleuss. This is a subset of the children's standardized math scores. And this is the computer's prediction of each child's score, based on playing some Curious George gaems. The prediction is astonishingly accurate, especially considering the fact that these games weren't built for aemsnssest. The team that did this study believes that games like these can teach us more about a child's cognitive learning than a standardized test can. What if games could ruedce testing time in the classroom? What if they could reduce tsiteng anxiety? How could they give tecraehs snapshots of insight to help them better focus their ivueiildzdanid learning?

Our producer in Boston, WGBH, created a series of Curious George games focused on math. And researchers came in and had 80 preschoolers play these games. They then gave all 80 of those preschoolers a standardized math test. We could see early on that these games were actually helping kids understand some key skills. But our partners at UCLA wanted us to dig deeper. They focus on data analysis and student assessment. And they wanted to take that back-end game-play data and see if they could use it to predict a child's math scores. So they made a neural net — they essentially trained the computer to use this data, and here are the results. This is a subset of the children's standardized math scores. And this is the computer's prediction of each child's score, based on playing some Curious George games. The prediction is astonishingly accurate, especially considering the fact that these games weren't built for assessment. The team that did this study believes that games like these can teach us more about a child's cognitive learning than a standardized test can. What if games could reduce testing time in the classroom? What if they could reduce testing anxiety? How could they give teachers snapshots of insight to help them better focus their individualized learning?
