New Test for Computers: Grading Essays at College Level

New Test for Computers: Grading Essays at College Level | cognition | Scoop.it
A system developed by a joint venture between Harvard and M.I.T. uses artificial intelligence to assess student papers and short written answers, freeing instructors for other tasks.
FastTFriend's insight:

Imagine taking a college exam, and, instead of handing in a blue book and getting a grade from a professor a few weeks later, clicking the “send” button when you are done and receiving a grade back instantly, your essay scored by a software program. And then, instead of being done with that exam, imagine that the system would immediately let you rewrite the test to try to improve your grade.


EdX, the nonprofit enterprise founded by Harvard and the Massachusetts Institute of Technology to offer courses on the Internet, has just introduced such a system and will make its automated software available free on the Web to any institution that wants to use it. The software uses artificial intelligence to grade student essays and short written answers, freeing professors for other tasks.

The Authority of Ideas

The Authority of Ideas | cognition | Scoop.it

What will historians say about us 250 years from now? Larry Summers, former Harvard University president and economic adviser to President Obama, asks this question in a thought-provoking eSeminar about the evolution of ideas and the critical importance of education in an increasingly multi-faceted world.
This will be a moment in history when the world evolved from a world governed by the idea of authority to a world governed by the authority of ideas, says Summers. Then he tells you how to be a part of the next great revolution.

Critical Thinking Is Best Taught Outside the Classroom: Scientific American

Critical Thinking Is Best Taught Outside the Classroom: Scientific American | cognition | Scoop.it
Critical thinking is a teachable skill best taught outside the K–12 classroom
FastTFriend's insight:

Museums and other institutions of informal learning may be better suited to teach this skill than elementary and secondary schools. At the Exploratorium in San Francisco, we recently studied how learning to ask good questions can affect the quality of people's scientific inquiry. We found that when we taught participants to ask “What if?” and “How can?” questions that nobody present would know the answer to and that would spark exploration, they engaged in better inquiry at the next exhibit—asking more questions, performing more experiments and making better interpretations of their results. Specifically, their questions became more comprehensive at the new exhibit. Rather than merely asking about something they wanted to try (“What happens when you block out a magnet?”), they tended to include both cause and effect in their question (“What if we pull this one magnet out and see if the other ones move by the same amount?”). Asking juicy questions appears to be a transferable skill for deepening collaborative inquiry into the science content found in exhibits.
