New study of low MOOC completion rates | Inside Higher Ed

By
Notice that technical courses and courses that were "automated" had higher completion rates. 
New study of low MOOC completion rates | Inside Higher Ed: The course with the highest rate of completion was "Functional Programming Principles in Scala," from Switzerland's Ecole Polytechnique Federale de Lausanne, offered on the MOOC platform Coursera. According to Jordan's research, some 19.2 percent of the 50,000 students who enrolled completed the course. 
At the other end of the spectrum was "A History of the World since 1300" by Princeton University, also hosted by Coursera, which reportedly recruited 83,000 students with just 0.8 percent reaching the end. 
Five of the top six most-completed MOOCs relied on automatic marking alone, meaning that no peer assessment was required. Courses that relied purely on peer grading generally fared far worse in terms of the percentage of students reaching the end.
My assumptions:

Technical students do better in a technology-mediated course. Online is "normal" to these students.

Many technical individuals like to work alone, avoiding group work and collaborative learning. Again, the online situation works well for these students.

Practical Technology Skills

This blog is a revision to a column I wrote for Direct Media publications. Normally, I wouldn't repost something I wrote for hire, and I certainly don't wish to anger one of my publishers. However, since this blog is primarily accessed by one of my graduate seminars, I think the publisher will appreciate that I am extending my thoughts for educational purposes. I'm also more than willing to encourage businesses to visit the Direct Media home page . Page numbers seemed to be a half-inch lower on each successive page. I stared at the mid-term paper, handed in to me by a junior at the university, and thought back to my fights with dot-matrix printers. When I was an undergrad, my Epson FX/80 printer jammed often and would sometimes rip pages after the sprockets slipped out of alignment with the punched holes of the perforated paper. Surely the undergraduate author of this paper suffered the curse of a similarly possessed printer, I told myself. “I guess when I changed the ma...

Robots for Home: Not Yet the Jetsons

By
NXT Robot (Photo credit: Wikipedia ) Visalia Direct: Virtual Valley November  3, 2014 Deadline December 2014 Issue Robots for Home: Not Yet the Jetsons Rosie the robot maintained the Jetson household more than 50 years ago. To the disappoint of many of us who still enjoy the classic 1960s cartoon, Rosie remains science fiction. The only robots in our houses are round bumper cars that vacuum floors. The iRobot Roomba offers no witty banter and no sighs of exasperation. Growing up, I expected Twiki, the android that followed Buck Rogers about for no apparent reason, to become a reality. After all, Twiki didn’t do anything except carry a much smarter talking computer about his neck. Sadly, Rogers was stuck in the twenty-fifth century. All the good androids and robots seem to be way off in the future or in other galaxies. Although we have no Rosie, robots are on the rise. They build our cars, deliver medications, defuse bombs, explore planets and even perform surgeries. M...

Human Readers for Tests

By
As readers of my blogs know, I'm never opposed to using technology when it is an effective tool. I am opposed to the blind embrace of the latest trends without critical examination of the potential side effects. Computer-assisted grading, I can endorse to some extent because I use software to help me analyze student papers — and my own writings. But, I cannot and will not endorse any system that gives weight to the computer-based scoring. If you're a teacher, consider this petition: http://humanreaders.org/petition/index.php Now, I also want to add a critical comment on human graders. If the graders of standardized tests are using rigid scoring rubrics, they are little better than software algorithms. Bad grading is bad grading. Inflexible = bad. Again, I am not opposed to using a computer for fact checking, some plagiarism verification, and as formatting aids. Computers can and do help many of us write more effectively. But, I don't use computers to grade pape...
