Brain Scan Can Predict Math Mistakes
itwbennett writes "Computer Science Ph.D. candidate Federico Cirett says that he can predict with 80 percent accuracy when someone is about to make a mistake on a math question. Using an EEG machine, Cirett can identify the patterns in a volunteer's thinking that are likely to result in an error 20 seconds or so before it's made. 'If we can detect when they are going to fail, maybe we can change the text or switch the question to give them another one at a different level of difficulty, but also to keep them engaged,' Cirett said. 'Brain wave data is the nearest thing we have to really know when the students are having problems.' He will present a paper on his findings at the User Modeling, Adaptation and Personalization conference in July."

Most people have been raised with the notion that it's more important to appear competent than be competent. There's several college-themed cartoons out there about that express hatred for "The Question Guy"... and most people are acutely aware that asking questions on material is a great way to earn the irritation and ostracism of your peers, who feel they have better things to do than get an education and really just want to go through the motions and get out.
This is another technology that's trying to solve a social problem, and like every attempt in that regard, it will fail, be impractical, and people will try to defeat it -- because they don't see the point and they don't want to appear incompetent. In 20 years, we'll be getting coached on how to have the right brain wave patterns for getting through the airport unmolested, how to cheat on your final and not get detected by the brain wave readers, etc.
The problem is in our social values and attitudes. It's systemic and institutional. No technology can fix that, however advanced.

Say we get this system to 100% accuracy. We know ahead of time that little Jimmy will not be able to solve this math problem. Little Jimmy has exhausted his options and has become stuck. Then what is the point of wasting time having him stare at it? I would take this as an alert that little Jimmy needs help, to intervene, and get little Jimmy learning again.
