life as a public school teacher in the San Francisco Bay Area in 2021.

Adam Cadre:

Even before the advent of the internets, catching students cheating was generally not particularly hard.  When a kid who can’t string a sentence together in class shows up with an essay full of phrases like “prone to disintegration” and “underscore the paradoxes”, something doesn’t add up.  (The appearance of the word “whilst” is another reliable red flag.)  Catching this sort of malfeasance has gotten even easier with the development of plagiarism detection software.  You click on a student’s submission and it pops onto the screen with the bits that have been copied from Sparknotes already highlighted.  Recently I encountered a student who thought that he had figured out an ingenious way to defeat these programs.  You know how sometimes you will run a web search on a phrase and it pulls up a bunch of sites with URLs that look like randomly generated passwords, whose preview text reveals that they collect other people’s posts and run them through thesaurus software?  This kid turned in a bunch of assignments that looked like that preview text.  I had asked students to write responses to each chapter as they read through Philip K. Dick’s The Man in the High Castle; here was how one of this kid’s submissions began:
In chapet 4 candidates welding abilities were sharpened at W-M corporation which makes created Iron articles even as pre-war American ancient Rarity phonies, sold at places like childan’s shop. the biggest interest from the Japanese has made an immense Marketplace for such things and no one addresses them intently.

Here is the original text from gradesaver.com:

Frank’s welding skills were honed at W-M Corporation, which makes wrought-iron objects as well as pre-war American artifact forgeries, sold at places like Childan’s shop. The massive demand from the Japanese has created a huge market for such items, and no one questions them very closely.

What I found particularly amusing was that, as you can see above, one of the main characters is named Frank; the student’s responses repeatedly referred to this character as “Candid” (which, above, was further mutated into “candidate”).  And the plagiarism detection software was indeed fooled!  What the student didn’t realize is that teachers don’t need software to be able to tell the difference between honestly composed sentences and computer-generated gibberish.
