More Stanford Computing Courses Go Free 124
mikejuk writes "Following on the recent Slashdot item on the availability of a free Stanford AI course there is news that two other Stanford Computer Science courses are also joining in this 'bold experiment in distributed education' in which students not only have access to lecture videos and other course materials but will actively participate by submitting assignments and getting regular feedback on their progress. The subjects are Machine Learning with Andrew Ng and Database with Jennifer Widom. This open approach looks as if it might be a success with well over 100,000 prospective students signing up to the AI course alone."

You know, good teachers have known for years that "lecturing" without interaction is pretty stupid. Yeah, when colleges have lecture classes with a thousand students in them, that's pretty stupid, too.
The best approach is generally a hybrid -- lecturer presents material, and as he/she goes, he/she asks questions, poses problems, and gets students to participate in coming up with the material as it is presented.

You're supposed to do the readings before class, and that's typically how instructors assign them so that you've got a basis for listening during the lecture.
I'm using the term lecture somewhat loosely as you're really not supposed to be talking for more than about 10 minutes tops without some form of student engagement. Lecturing longer than that tends to be counterproductive and make it hard to follow. Also it probably means that you haven't divided the material up into reasonable size bites.

In classes that I have had where recorded lectures have been used the discussions during classroom time were pretty heavy with Q&A. A professor called on students with a basic question validating they got the concepts from the lecture, then the professor would follow up with a more advanced question to see if they could apply the concepts rather than merely repeat them back.

It is not bad business, because they have set the size of their "customer" pool, and the number of prospective customers is larger than the size they have set.
Besides, buying the degree somewhere else is pretty useless. Completion of the courses in TFA will not get you credit:
Online students who successfully complete their chosen course will receive a statement of accomplishment from the instructor, which will include information on how well you did and how your performance compared to other online students. Only students admitted to Stanford and enrolled in the regular course can receive credit or a grade, so this is not a Stanford certificate.
In other words, you get a gold star and perhaps the ability to say that you did better than X% of hundreds of thousands of other slackers. No credential.
See how far you get with a prospective employer by saying, "I know my degree is from Upper Bucksnort State Teachers College, but I've completed free courses through private study in MIT's opencourseware and I have a gold star form letter from Stanford saying that it is not an official record from Stanford, but I did better than 80% of people who probably didn't put in much effort for no credit either."
College degrees are only useful for getting you in the door to your first job or two. An elite name gets more attention in most cases. Offering free "unofficial" Stanford gold stars to anonymous internet folks is not going to dilute Stanford's ability to make money or to place its own graduates.
