The announcement last week of the University of Wisconsin System?s new “flexible degree” is a worthy start. The program, to be rolled out over the next year, will allow students to learn online at their own pace and provide college credit for proving they?ve mastered skills learned at work. It?s about time the public education establishment started really shaking up the standard high school-to-college-to-career path. Economists and education-reform types have been saying for years that a changing world requires changing education models.
