Human Readers for Tests

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:

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 papers. Sometimes that distinction escapes my students at first, but eventually they recognize that I'm using software to help me highlight potential problems.

Software is better than ever at grammar and spelling, but it isn't perfect. There are also new applications that can fact check documents, a project funded by the Knight Foundation to fact check political speeches and papers. But, computers cannot yet grade anything that cannot be flowcharted and categorized.

Can I grade a multiple choice test with a computer? Certainly. Can I grade a spelling test automatically? Sure. But, the computer might not recognize any patterns in the errors a student makes. In time, maybe a computer will be able to grade a test and offer suggestions for future study. But, computer technology is years, maybe decades, from being able to "grade" an essay, poem, or creative work.

Even when computers do reach that capability, I want a human to have the final say on grading students. We already are reducing too much education to an isolated process, focused on high-stakes test results. We need some humanity, for lack of a better word, in our classes.

Slowly Rebooting in 286 Mode

The lumbar radiculopathy, which sounds too much like "ridiculously" for me, hasn't faded completely. My left leg still cramps, tingles, and hurts with sharp pains. My mind remains cloudy, too, even as I stop taking painkillers for the back pain and a recent surgery.

Efforts to reboot and get back on track intellectually, physically, and emotionally are off to a slow, grinding start. It reminds me of an old 80286 PC, the infamously confused Intel CPU that wasn't sure what it was meant to be. And this was before the "SX" fiascos, which wedded 32-bit CPU cores with 16-bit connections. The 80286 was supposed to be able to multitask, but design flaws resulted in a first-generation that was useless to operating system vendors.

My back, my knees, my ankles are each making noises like those old computers.

If I haven't already lost you as a reader, the basic problem is that my mind cannot focus on one task for long without exhaustion and multitasking seems…

MarsEdit and Blogging

MarsEdit (Photo credit: Wikipedia) Mailing posts to blogs, a practice I adopted in 2005, allows a blogger like me to store copies of draft posts within email. If Blogger, WordPress, or the blogging platform of the moment crashes or for some other reason eats my posts, at least I have the original drafts of most entries. I find having such a nicely organized archive convenient — much easier than remembering to archive posts from Blogger or WordPress to my computer.

With this post, I am testing MarsEdit from Red Sweater Software based on recent reviews, including an overview on 9to5Mac.

Composing posts an email offers a fast way to prepare draft blogs, but the email does not always work well if you want to include basic formatting, images, and links to online resources. Submitting to Blogger via Apple Mail often produced complex HTML with unnecessary font and paragraph formatting styles. Problems with rich text led me to convert blog entries to plaintext in Apple Mail and then format th…

Let’s Make a Movie: Digital Filmmaking on a Budget

Every weekend a small group of filmmakers I know make at least one three-minute movie and share the short film on their YouTube channel, 3X7 Films.

Inspired by the 48-Hour Film Project (, my colleagues started to joke about entering a 48-hour contest each month. Someone suggested that it might be possible to make a three-minute movie every week. Soon, 3X7 Films was launched as a Facebook group and members started to assemble teams to make movies.

The 48-Hour Film Project, also known as 48HFP, launched in 2001 by Mark Ruppert. He convinced some colleagues in Washington, D.C., that they could make a movie in 48 hours. The idea became a friendly competition. Fifteen years later, 48HFP is an international phenomenon, with competitions in cities around the world. Regional winners compete in national and international festivals.

On a Friday night, teams gathe…
