Computer for Learning

Computer had been a terrific innovation for learning. With the Internet and Google, almost any topic within the range of public knowledge can be searched for. With the iPad, learning experience makes another step forward with better UI and ease of use. However, the educational system is slow to embrace the digital revolution. So far, the biggest impact is recorded lecture materials. But computers have much more to offer. Technology aside, there are several areas that the educational system may improve.

Advanced knowledge is scattered over the Internet. Although private knowledge like whole process for semiconductor manufacturing is forbidden from the Internet, advanced public knowledge like physics is reachable, but without proper guidance, it's very inefficient to learn from the Internet. Gerard 't Hooft's initiative to teach graduate physics online is only half-successful. The educational system can use better organization of advanced public knowledge that may benefit learners worldwide.

The most obvious advantage Internet and the iPad offers is wide selection of materials. Print is expensive and restrictive, so printed materials often resemble a tiny sliver of the whole body of knowledge. Digitization removes the limitation, but most instructors use the Internet mostly for companion materials, rather than a portal for further study. The educational system should catch up to computers.

Furthermore, as the Internet transforms education, it also produces digital divide. Poor families with limited access to computers and networks are disadvantaged by the system, which brings the topic of computer welfare. The public sector should offer decent computers to the poor, so that everyone receives equal opportunity. Perhaps not all people are interested in programming, but the computer can make a difference in learning all sorts of stuff.

Computer welfare is a novel approach to equal opportunity for all. It seems that a well-functioning society should properly integrate computers into the learning process of all citizens.
