I’ve been teaching in higher education for 30 years and am soon retiring. I teach math. In every math course there is massive amounts of cheating on everything that is graded that is not proctored in a classroom setting. Locking down browsers and whatnot does not prevent cheating.

The only solution is to require face-to-face proctored exams and not allow students to use technology of any kind while taking the test. But any teacher doing this will end up with no students signing up for their class. The only solution I see is the Higher Learning Commission mandating this for all classes.

But even requiring in person proctored exams is not the full solution. Students are not used to doing the necessary work to learn. They are used to doing the necessary work to pass. And that work is increasingly cheating. It’s a clusterfuck. I have calculus students who don’t know how to work with fractions. If we did truly devise a system that prevents cheating we’ll see that a very high percentage of current college students are not ready to be truly college educated.

K-12 needs to be changed as well.

My personal take, we’ve made the cost of failure to high and cheating too easy.

As a student, the only thing the next institution will see is GPA, school, major. Roughly in that order. If the cost of not getting an A is exclusion from future opportunities- then students will reject exclusion by taking easier classes or cheating.

As someone who studied physics and came out with a 2.7 GPA due to studying what I wanted (the hard classes) and not cheating (as I did what I wanted) - I can say that there are consequences to this approach.

In my opinion, the solution is to reduce the reliance on assessments which are prone to cheating or which in the real world would be done by computer.

Serious question from someone who is regularly tasked with hiring Juniors. What IS a good assessment for entry-level/right out of college positions?

-> GPA can be gamed, as laid out.

-> Take Home assessments can mostly be gamed, I want to assess how you think, now which tools you use.

-> Personality tests favor the outgoing/extroverts

-> On-location tests/leet code are a crapshoot.

What should be best practice here? Ideally something that controls for first-time interviewer jitters.

My process is as follows:

1. Live coding, in Zoom or in person. Don't play gotcha on the language choice (unless there's a massive gulf in skill transference, like a webdev interviewing for an embedded C position). Pretend the 13 languages on the candidate's resume don't exist. Tell them it can be any of these x languages, which are every language you the interviewer feel comfortable to write leetcode in.

2. Write some easy problem in that language. I always go with some inefficient layout for the input data, then ask for something that's only one or two for loops away from being a stupid simple brute force solution. Good hygienic layout of the input data would have made this a single hashtable lookup.

3. Run the 45 minute interview with a lot of patience and positive feedback. One of the best hires in our department had first-time interview nerves and couldn't do anything for the first 10 minutes. I just complimented their thinking-out-loud, laughed at their jokes, and kept them from overthinking it.

4. 80% of interviewees will fail to write a meaningful loop. For the other 20%, spend the rest of the time talking about possible tradeoffs, anecdotes they share about similar design decisions, etc. The candidate will think you're writing in your laptop their scoring criteria, but you already passed them and generated a pop-sci personality test result for them of questionable accuracy. You're fishing for specific things to support your assessment, like they're good at both making and reviewing snap decisions and in doing so successfully saved a good portion of interview time, which contributed to their success. If it uses a weasel word, it's worth writing down.

5. Spend an hour (yes, longer than the interview) (and yes, block this time off in your calender) writing your interview assessment. Start with a 90s-television-tier assessment. For example, the candidate is nimble, constantly creating compelling technical alternatives, but is not focused on one, and they often communicate in jargon. DO NOT WRITE THIS DOWN. This is the lesson you want the geriatric senior management to take away from reading your assessment. Compose relatively long (I do 4 paragraphs minimum) prose that describes a slightly less stereotyped version of the above with plenty of examples, which you spent most of the interview time specifically fishing for. If the narrative is contradicted by the evidence, it's okay to re-write the narrative so the evidence fits.

6. When you're done, skim the job description you're hiring for. If there's a mismatch between that and the narrative you wrote, change your decision to no hire and explain why.

Doing this has gotten me eye rolls from coworkers but compliments at director+ level. I have had the CTO quote me once in a meeting. Putting that in my performance review packet made the whole thing worth it.
