South Korea to invest in robot teachers

Korean school officials are touting the success of a 14-week trial program that supplemented preschool and kindergarten classrooms with robot teachers. The $1.4 test program featured a variety of edu-bots assisting human teachers in 21 schools. Officials are so pleased with the results; they have already laid plans to expand "R-Learning" in 2011 with an $8.69 million investment that will broaden the program to 500 preschools. By 2012, the investment will be more than quadrupled to $36 million, expanding to 8,000 kindergarten and preschools by 2013.
