I’ve spent the last few days doing what I imagine a lot of people have been doing: thinking about the verdict in the George Zimmerman trial. I didn’t automatically expect a particular verdict; ever since Rodney King, O.J. Simpson, William Kennedy Smith, Casey Anthony . . . (the list goes on), I’ve realized that sitting on a jury and following the parameters established by legal definitions is a very different task than reading news accounts and following gut instincts.

Still not sure what I think about Edward Snowden. First, he blows everything we say about needing a college degree to get a good job–he didn’t even finish high school and yet landed a position that gave him access to highly classified information. Second, I’m not sure whether to see him as a whistleblowing hero or a traitor. Ever since 9/11, we seem to be saying that we’re willing to trade some personal freedoms for greater national security, and yet when we see what that looks like in real life, we understandably don’t like it. I thought David Brooks wrote an insightful column on Snowden a few days ago in The New York Times: The Solitary Leaker – NYTimes.com.
I read an interesting piece recently in The New York Times by A.J. Jacobs, a writer for Esquire magazine. It’s on the Time’s website under the title, Grading the MOOC University. Jacobs describes his experience taking several open online courses from such providers as Coursera, Udacity, and Edx.
I found the following excerpt intriguing: Continue reading
I just read this piece by John Markoff of The New York Times and found it intriguing. Apparently, we’re still trying to figure out a way of automating the learning process. Apart from the fact that students are figuring out ways to do end runs around the artificial intelligence essay grading software, does a computer tell students when they have hit on idea worth exploring further?
In a recent New York Times, there was an article by Randall Stross, “The Algorithm Didn’t Like My Essay.” I found it interesting because I had posted back in May on a similar article about “robograding.” Stross writes about how consistent computer-scored essays are to human-scored essays in standardized tests such as the ACT and SAT. He then postulates that using computerized essay grading could free up human resources to interact with students on more meaningful issues at more meaningful levels.
While I don’t disagree with him on a philosophical level–what teacher doesn’t want ways to work smarter and not burn out on repetitive tasks–the fact remains that at present there is no substitute for human interaction when it comes to written expression. For the computerized scoring functions, the grammar and style checker that comes standard with Word does about as well as the standalone programs that supposedly excel at finding errors or at rating levels of sophistication. But none of these programs actually “reads” what a student has written. They can’t detect irony, they can’t identify falsehood, and they can’t recognize empty ideas.
The dilemma is that there are certain assessments that cannot be done quickly or automatically–at least not if they are to mean anything. Perhaps we should eliminate written essays from any kind of standardized tests. Stroll points out that even human scorers of such tests typically spend three minutes or less on each essay. Having been one of these scorers, I would agree with that estimate. In such settings, you train yourself to look for very specific things in a piece of writing; most of them relate more to modes of expression rather than modes of thought. It reminds me of Billy Crystal’s line from years ago, “it is better to look good than to feel good, dahling.”
In the next week, the students in my summer online composition course will turn in their rough drafts of their first essay, and they will then spend two days reading each others’ writing and commenting on it (as will I). Then they will go back to the drawing board (I hope) and spend time wrestling not just with comma splices but with the ideas that need further development. I am just nosy enough to want to know what they really thought about the readings I chose for the course, and I am naive enough to believe our future leaders in business, technological innovation, parenting, and education will be those who were more concerned with the content of their ideas than with the “color” of those ideas’ skin (apologies to Martin Luther King, Jr.).
It must be the end of the semester: I’m developing double-vision and looking for any break I can find from grading. Coincidentally, The New York Times just put out an article on the virtues and drawbacks of computer grading programs, or e-raters, which are now being used to grade essays on standardized tests such as the SAT.
Apparently, they do as good a job, or better, than I do in scoring essays, with one exception. They can’t discern truth, and poetry blows their circuits. I guess computers never met a metaphor they liked, and irony is lost on them.
Looks like my job is safe–for now.
I read an interesting article in today’s Times, titled “Wonder Dog,” about the amazing ways service dogs can affect the lives of their families. The opening anecdote focused on a family in Georgia whose son has behavioral and cognitive issues stemming from prenatal exposure to alcohol. After trying all kinds of interventions, the mom was encouraged to consider a dog who was specifically trained to intervene in her son’s frequent tantrums. Over time, the family has seen the tantrums decrease, and they have also seen some striking developments in their son’s cognitive development.
The article also talks about the training process these dogs go through, which is rigorous and highly specific. They can be trained to perform physical tasks in a home environment–everything from opening doors and turning on light switches to getting items out of the refrigerator and helping someone undress–as well as to recognize physical symptoms, such as impending seizures. Here is a video showing the training process in action.
Around our house, we don’t have dogs trained for service. At times, one of the 14-yr-old “seniors”–Buddy–forgets that he’s housetrained. But, as this photo attests, we’re a thoroughly integrated family. The dogs let us know when the atmospheric pressure drops and a front is moving in, Digory–the other “old man”–makes frequent rounds of the house to make sure everyone is accounted for, and the beagles . . . well, the beagles make sure that any crumbs get licked up, whether they’re on the floor, on a low table, or in an open pantry closet.
