Is this going towards a future where students do not need to be physical present on the campus?
Actually, the TEAL approach that replaced the large freshman physics lectures at MIT places a heavier emphasis on attendance. In a traditional lecture the professor doesn't know most of the students, and doesn't really care if 50% of them stop showing up after the first week. With TEAL there are interactive portions of the class (such as answering multiple choice questions with a personal remote) which are tracked and factored into the student's grade. In other words, if you don't show up, you can't get an A (no matter how well you have mastered the material).
Personally I don't think this is the best approach, but it certainly isn't forgiving of a student's absence from class.
As a side note, when I was a freshman, many of my classmates did not find the TEAL lectures to be terribly effective in teaching the material. Frequently they would go back into the video archive after class and watch recordings of the "traditional" lectures from years past to actually learn what was being taught. They just went to the TEAL lectures because they didn't want to loose their participation credit.

We've got means to extract oxygen from water, a portable bar, and even ways to deprive entire server farms of the sustenance, but a new project being tackled by Lockheed Martin is hoping to create O2 on the moon. A critical part of NASA's PILOT (Precursor In-situ Lunar Oxygen Testbed) initiative, this digger bot will work hand-in-hand with a "processing plant that will add hydrogen to moon soil, heat it to 1,652-degrees Fahrenheit, condense the steam, and finally extract the oxygen." Additionally, the blue LIDAR (Light Detection And Ranging) box atop the three-foot-long machine can assist it in locating "oxygen-rich lunar soil and autonomously carry it to a processing plant." The overriding goal is to use the newly extracted O2 for air, or moreover, to combine it with hydrogen and produce water for the four astronauts that the lunar base could support. Unfortunately, there's no timetable as to when we'll actually see the PILOT roll into action, but we're most interested in porting this bad boy over to Mars along with half the traffic in LA.Read | Permalink | Email this | Comments
