In a traditional university setting, a student pays to register for a course. The student shows up. A professor hands out an outline, assigns readings, stands at the front and lectures. Students take notes and ask questions. Then there is a test or an essay.

But with advancing online tools innovative educators are examining new ways to break out of this one-to-many model of education, through a concept called massively open online courses. The idea is to use open-source learning tools to make courses transparent and open to all, harnessing the knowledge of anyone who is interested in a topic.

George Siemens, along with colleague Stephen Downes, tried out the open course concept in fall 2008 through the University of Manitoba in a course called Connectivism and Connective Knowledge, or CCK08 for short. The course would allow 25 students to register, pay and receive credit for the course. All of the course content, including discussion boards, course readings, podcasts and any other teaching materials, was open to anyone who had an internet connection and created a user profile.

While most of our classrooms were built under the assumption that information is scarce and hard to find, nearly the entire body of human knowledge now flows through and around these rooms in one form or another, ready to be accessed by laptops, cellphones, and iPods. Classrooms built to re-enforce the top-down authoritative knowledge of the teacher are now enveloped by a cloud of ubiquitous digital information where knowledge is made, not found, and authority is continuously negotiated through discussion and participation.

This new media environment can be enormously disruptive to our current teaching methods and philosophies.

Our physical structures were built prior to an age of infinite information, our social structures formed to serve different purposes than those needed now, and the cognitive structures we have developed along the way now struggle to grapple with the emerging possibilities.

Colleges no longer simply want to know what their students know, but how they think.

Higher-order thinking skills are "something that schools are paying a little bit more attention to these days," says Jeffrey Steedle, a measurement scientist at the Council for Aid to Education, whose Collegiate Learning Assessment essays are used at several hundred colleges to test students' abilities to synthesize arguments and write persuasively. "It's largely in response to the recognition that these skills are needed to be competitive in the global marketplace."

But educators also say that paper-and-pencil examinations have limits—for one thing, knowing that you are being tested can drag down performance—and they are looking for new methods to measure skills like critical thinking, creativity, and persistence.
