http://www.pbs.org/wgbh/nova/tech/smartest-machine-on-earth.html The USA Public Broadcasting System aired this 52 minutes long television show in the Nova series on 11.02.09. The host and various computer scientists discuss in very general non-technical terms how the I.B.M. artificially intelligent machine "Watson" has been taught to play the TV game show "Jeopardy" better than the two most expert human players of that game. If "Watson" can learn to play Jeopardy and soon will be taught to give expert medical advice, it also can be taught the rudiments of the knowledge and skill sets to be acquired by K-12 students in the USA. Then it can be taught to teach that knowledge and those skills.
