Reading this semester's essays, I note several common features that I haven't seen like this in past years:

- very few typos and grammatical oddities (which are otherwise common in first year students)
- very repetitive

I think I'm seeing Chat-GPT at work...

I just asked Chat-GPT to write an essay for the question I asked the students to write about and it's definitely using the same patterns and expressions that I see all over the student essays. So I fear I have to conclude that something like 75% of submissions are Chat-GPT plagiarized.
Another hint: students usually are very fond of providing tables of content, even for the shortest of essays. But this year, very few essays have TOCs. But Chat-GPT also doesn't give TOCs...

After five Chat-GPT essays in a row finally a real original essay:

- 10 item TOC for a 9 page essay
- "Oral" sentence structure in the first paragraphs
- typos and stylistic errors down to non-existent words

@philippsteinkrueger This is depressing to read. That apparently this many students are prepared to cheat given the chance. And also that they didn’t even bother to try harder to hide the fact.
@wzhkevin I think it’s because they have heard about Chat-GPT and they give it a try and they are impressed by the output and so they don’t even think that someone who reads lots of essays might pick up on the differences with human created content… they’ll probably improve their efforts if given the chance…
