Facial Recognition Tech Helps ID Bomb Suspects

wanted BostonImproved technology played a big role in the identification of the two primary suspects in the Boston Marathon bombing.

Law enforcement officials were deluged with digital images and video after asking anyone who was in the area during the event to submit them. Traditionally it would take hundreds of officers countless hours to examine all of that media, but new versions of facial recognition technology have made that task much more manageable.

CNet explains how this tech works: "The software, which can help pick a person out of crowd, looks for differentiating features -- from the shape of a mouth to the ridge on a nose to the distance between a pair of eyes.

3VR in San Francisco has developed software that extracts information from video and then makes it searchable for its clients, which include retailers, banks, security firms and law enforcement."

Got A Minute, Two or Five? Ideas for...

I am a strong believer in having kids on task throughout the class session. Lessons rarely finished “early” and if they did, I always had something for the kids to do until the class ended. I usually didn’t give students “free time” to start homework or to read a book or magazine. That’s because that seemed to be a signal to have a chat fest. If I started the class by quickly checking homework or doing some clerical things, I had a bell ringer (is this term still used?) or activity for the...

Several years ago, a colleague and I conducted a pilot study that involved teaching 24 gifted elementary students how to meditate and practice other mindfulness techniques. Mindfulness has many definitions but generally involves training one’s mind to purposely pay attention. Each Friday, we met in the school’s media center and had the students practice breathing methods, visualization, yoga, mindful eating and walking, and gratitude. Following each practice, we interviewed the students...

Recently, I had the opportunity to learn about the British educational system from a visiting professor from Cambridge University. When the issue of standardized testing came up, she used a memorable analogy. She said schools spend too much time “weighing the pig, expecting it to grow.” The expression, which apparently originated from a story by a farmer to his son in the early 1900s, teaches that the activity of weighing or measuring does not produce results or improve performance—it simply...
