Students have been given online short essay exams, and the kids have discovered that they are graded by artificial intelligence, and you can ace the test with two sentences and a word salad.

The problem here is not AI. The problem here is the tech bros trying to sell crap AI as gold:

On Monday, Dana Simmons came downstairs to find her 12-year-old son, Lazare, in tears. He’d completed the first assignment for his seventh-grade history class on Edgenuity, an online platform for virtual learning. He’d received a 50 out of 100. That wasn’t on a practice test — it was his real grade.

………

At first, Simmons tried to console her son. “I was like well, you know, some teachers grade really harshly at the beginning,” said Simmons, who is a history professor herself. Then, Lazare clarified that he’d received his grade less than a second after submitting his answers. A teacher couldn’t have read his response in that time, Simmons knew — her son was being graded by an algorithm.

Simmons watched Lazare complete more assignments. She looked at the correct answers, which Edgenuity revealed at the end. She surmised that Edgenuity’s AI was scanning for specific keywords that it expected to see in students’ answers. And she decided to game it.



Now, for every short-answer question, Lazare writes two long sentences followed by a disjointed list of keywords — anything that seems relevant to the question. “The questions are things like… ‘What was the advantage of Constantinople’s location for the power of the Byzantine empire,’” Simmons says. “So you go through, okay, what are the possible keywords that are associated with this? Wealth, caravan, ship, India, China, Middle East, he just threw all of those words in.”

………

Apparently, that “word salad” is enough to get a perfect grade on any short-answer question in an Edgenuity test.

Algorithm update. He cracked it: Two full sentences, followed by a word salad of all possibly applicable keywords. 100% on every assignment. Students on @EdgenuityInc, there's your ticket. He went from an F to an A+ without learning a thing.

This is typical of what we are getting from tech these days.

It seems that it’s all the late David Graeber’s “Bullsh%$ Jobs.”
