Dialogue: 0,0:02:28.15,0:02:30.67,Default,,0000,0000,0000,,so while students are solving math problems,
Dialogue: 0,0:02:30.67,0:02:34.04,Default,,0000,0000,0000,,a teacher can quickly find out who's paying attention and who's not.

Dialogue: 0,0:02:58.28,0:03:01.14,Default,,0000,0000,0000,,and what they exactly measure isn't as clear.
Dialogue: 0,0:03:04.31,0:03:07.90,Default,,0000,0000,0000,,We were curious if the headbands could actually measure concentration.
Dialogue: 0,0:03:07.90,0:03:10.02,Default,,0000,0000,0000,,So, one of our reporters tried on the device.
Dialogue: 0,0:03:16.27,0:03:20.51,Default,,0000,0000,0000,,This is a new technology with, still, fairly little research behind it.

Dialogue: 0,0:03:26.01,0:03:28.02,Default,,0000,0000,0000,,He was surprised to learn that this tech,
Dialogue: 0,0:03:28.02,0:03:31.66,Default,,0000,0000,0000,,called electroencephalography, also known as EEG,
Dialogue: 0,0:03:31.66,0:03:34.87,Default,,0000,0000,0000,,is being used in the classroom on children.
Dialogue: 0,0:03:34.87,0:03:38.21,Default,,0000,0000,0000,,It's usually used by doctors in hospitals and labs.
Dialogue: 0,0:03:38.21,0:03:41.06,Default,,0000,0000,0000,,EEG is very susceptible to artifacts
Dialogue: 0,0:03:41.06,0:03:47.51,Default,,0000,0000,0000,,and so, if you are itchy, or just a little fidgety or the EEG wasn't setup\Nproperly,
Dialogue: 0,0:03:47.51,0:03:52.01,Default,,0000,0000,0000,,so that the electrodes didn't have a good contact, effects the signal.
Dialogue: 0,0:03:52.01,0:03:54.58,Default,,0000,0000,0000,,Despite the chances for false readings,
Dialogue: 0,0:03:54.58,0:03:57.93,Default,,0000,0000,0000,,teachers told us the headbands have forced students
Dialogue: 0,0:03:57.93,0:03:59.46,Default,,0000,0000,0000,,to become more disciplined.
Dialogue: 0,0:04:06.59,0:04:09.66,Default,,0000,0000,0000,,Teachers say the students now pay better attention during class,
Dialogue: 0,0:04:09.66,0:04:13.75,Default,,0000,0000,0000,,and that has made them study harder, and achieve higher scores.
Dialogue: 0,0:04:21.13,0:04:23.37,Default,,0000,0000,0000,,But, not all students are as enthusiastic.
Dialogue: 0,0:04:32.33,0:04:34.92,Default,,0000,0000,0000,,This fifth grader, whom we caught dozing off in class,
Dialogue: 0,0:04:34.92,0:04:38.74,Default,,0000,0000,0000,,told us his parents punish him for low attention scores,
Dialogue: 0,0:04:38.74,0:04:42.62,Default,,0000,0000,0000,,and that kind of data adds a new kind of pressure for students.
Dialogue: 0,0:04:53.09,0:04:57.93,Default,,0000,0000,0000,,Companies we interviewed said the data can go to government funded research projects.
Dialogue: 0,0:04:57.93,0:05:01.92,Default,,0000,0000,0000,,We spoke to parents who were unclear about where the data ended up,
Dialogue: 0,0:05:01.92,0:05:04.81,Default,,0000,0000,0000,,and they didn't seem to care too much.
Dialogue: 0,0:05:04.81,0:05:08.80,Default,,0000,0000,0000,,Zanto says, there's likely no privacy protection at all.
Dialogue: 0,0:05:08.80,0:05:12.67,Default,,0000,0000,0000,,The classroom is you're trying to make an assessment of an individual student,
Dialogue: 0,0:05:12.67,0:05:14.49,Default,,0000,0000,0000,,you really can't anatomize it.
Dialogue: 0,0:05:16.32,0:05:20.21,Default,,0000,0000,0000,,Experts and citizens alike are sounding alarms
Dialogue: 0,0:05:20.21,0:05:23.63,Default,,0000,0000,0000,,about various aspects of the country's huge push into artificial intelligence.
Dialogue: 0,0:05:24.56,0:05:28.20,Default,,0000,0000,0000,,These classrooms are laboratories for future generations,
Dialogue: 0,0:05:28.20,0:05:34.06,Default,,0000,0000,0000,,and while these new tools may potentially help some two hundred million students raise their grades,
Dialogue: 0,0:05:34.06,0:05:38.73,Default,,0000,0000,0000,,just how this all works out won't be apparent until they become adult citizens.
