Ethan and Lilach Mollick’s paper Assigning AI: Seven Approaches for College students with Prompts explores seven methods to make use of AI in educating. (Whereas this paper is eminently readable, there’s a non-academic model in Ethan Mollick’s Substack.) The article describes seven roles that an AI bot like ChatGPT would possibly play within the training course of: Mentor, Tutor, Coach, Pupil, Teammate, Pupil, Simulator, and Device. For every position, it features a detailed instance of a immediate that can be utilized to implement that position, together with an instance of a ChatGPT session utilizing the immediate, dangers of utilizing the immediate, pointers for academics, directions for college kids, and directions to assist trainer construct their very own prompts.
The Mentor position is especially vital to the work we do at O’Reilly in coaching folks in new technical expertise. Programming (like some other talent) isn’t nearly studying the syntax and semantics of a programming language; it’s about studying to resolve issues successfully. That requires a mentor; Tim O’Reilly has at all times stated that our books must be like “somebody clever and skilled trying over your shoulder and making suggestions.” So I made a decision to offer the Mentor immediate a strive on some brief applications I’ve written. Right here’s what I realized–not significantly about programming, however about ChatGPT and automatic mentoring. I received’t reproduce the session (it was fairly lengthy). And I’ll say this now, and once more on the finish: what ChatGPT can do proper now has limitations, however it can definitely get higher, and it’ll in all probability get higher rapidly.

First, Ruby and Prime Numbers
I first tried a Ruby program I wrote about 10 years in the past: a easy prime quantity sieve. Maybe I’m obsessive about primes, however I selected this program as a result of it’s comparatively brief, and since I haven’t touched it for years, so I used to be considerably unfamiliar with the way it labored. I began by pasting within the full immediate from the article (it’s lengthy), answering ChatGPT’s preliminary questions on what I wished to perform and my background, and pasting within the Ruby script.
ChatGPT responded with some pretty primary recommendation about following frequent Ruby naming conventions and avoiding inline feedback (Rubyists used to suppose that code must be self-documenting. Sadly). It additionally made a degree a couple of places() technique name inside the program’s most important loop. That’s attention-grabbing–the places() was there for debugging, and I evidently forgot to take it out. It additionally made a helpful level about safety: whereas a chief quantity sieve raises few safety points, studying command line arguments immediately from ARGV relatively than utilizing a library for parsing choices might depart this system open to assault.
It additionally gave me a brand new model of this system with these modifications made. Rewriting this system wasn’t acceptable: a mentor ought to remark and supply recommendation, however shouldn’t rewrite your work. That must be as much as the learner. Nevertheless, it isn’t a significant issue. Stopping this rewrite is so simple as simply including “Don’t rewrite this system” to the immediate.
Second Attempt: Python and Information in Spreadsheets
My subsequent experiment was with a brief Python program that used the Pandas library to research survey knowledge saved in an Excel spreadsheet. This program had a couple of issues–as we’ll see.
ChatGPT’s Python mentoring didn’t differ a lot from Ruby: it recommended some stylistic modifications, reminiscent of utilizing snake-case variable names, utilizing f-strings (I don’t know why I didn’t; they’re one in every of my favourite options), encapsulating extra of this system’s logic in capabilities, and including some exception checking to catch doable errors within the Excel enter file. It additionally objected to my use of “No Reply” to fill empty cells. (Pandas usually converts empty cells to NaN, “not a quantity,” they usually’re frustratingly laborious to take care of.) Helpful suggestions, although hardly earthshaking. It could be laborious to argue in opposition to any of this recommendation, however on the identical time, there’s nothing I’d contemplate significantly insightful. If I have been a scholar, I’d quickly get annoyed after two or three applications yielded related responses.
After all, if my Python actually was that good, possibly I solely wanted a couple of cursory feedback about programming model–however my program wasn’t that good. So I made a decision to push ChatGPT a little bit more durable. First, I advised it that I suspected this system may very well be simplified through the use of the dataframe.groupby() operate within the Pandas library. (I hardly ever use groupby(), for no good purpose.) ChatGPT agreed–and whereas it’s good to have a supercomputer agree with you, that is hardly a radical suggestion. It’s a suggestion I’d have anticipated from a mentor who had used Python and Pandas to work with knowledge. I needed to make the suggestion myself.
ChatGPT obligingly rewrote the code–once more, I in all probability ought to have advised it to not. The ensuing code appeared cheap, although it made a not-so-subtle change in this system’s conduct: it filtered out the “No reply” rows after computing percentages, relatively than earlier than. It’s vital to be careful for minor modifications like this when asking ChatGPT to assist with programming. Such minor modifications occur often, they give the impression of being innocuous, however they’ll change the output. (A rigorous take a look at suite would have helped.) This was an vital lesson: you actually can’t assume that something ChatGPT does is right. Even when it’s syntactically right, even when it runs with out error messages, ChatGPT can introduce modifications that result in errors. Testing has at all times been vital (and under-utilized); with ChatGPT, it’s much more so.
Now for the following take a look at. I by accident omitted the ultimate traces of my program, which made numerous graphs utilizing Python’s matplotlib library. Whereas this omission didn’t have an effect on the info evaluation (it printed the outcomes on the terminal), a number of traces of code organized the info in a means that was handy for the graphing capabilities. These traces of code have been now a type of “lifeless code”: code that’s executed, however that has no impact on the consequence. Once more, I’d have anticipated a human mentor to be throughout this. I’d have anticipated them to say “Have a look at the info construction graph_data. The place is that knowledge used? If it isn’t used, why is it there?” I didn’t get that type of assist. A mentor who doesn’t level out issues within the code isn’t a lot of a mentor.
So my subsequent immediate requested for strategies about cleansing up the lifeless code. ChatGPT praised me for my perception and agreed that eradicating lifeless code was a good suggestion. However once more, I don’t need a mentor to reward me for having good concepts; I need a mentor to note what I ought to have seen, however didn’t. I need a mentor to show me to be careful for frequent programming errors, and that supply code inevitably degrades over time in case you’re not cautious–even because it’s improved and restructured.
ChatGPT additionally rewrote my program but once more. This remaining rewrite was incorrect–this model didn’t work. (It might need finished higher if I had been utilizing Code Interpreter, although Code Interpreter isn’t any assure of correctness.) That each is, and isn’t, a difficulty. It’s one more reminder that, if correctness is a criterion, you need to test and take a look at the whole lot ChatGPT generates rigorously. However–within the context of mentoring–I ought to have written a immediate that suppressed code technology; rewriting your program isn’t the mentor’s job. Moreover, I don’t suppose it’s a horrible downside if a mentor sometimes provides you poor recommendation. We’re all human (at the least, most of us). That’s a part of the educational expertise. And it’s vital for us to search out purposes for AI the place errors are tolerable.
So, what’s the rating?
- ChatGPT is nice at giving primary recommendation. However anybody who’s critical about studying will quickly need recommendation that goes past the fundamentals.
- ChatGPT can acknowledge when the consumer makes good strategies that transcend easy generalities, however is unable to make these strategies itself. This occurred twice: once I needed to ask it about
groupby(), and once I requested it about cleansing up the lifeless code. - Ideally, a mentor shouldn’t generate code. That may be fastened simply. Nevertheless, if you need ChatGPT to generate code implementing its strategies, you need to test rigorously for errors, a few of which can be delicate modifications in program’s conduct.
Not There But
Mentoring is a crucial software for language fashions, not the least as a result of it finesses one in every of their greatest issues, their tendency to make errors and create errors. A mentor that sometimes makes a nasty suggestion isn’t actually an issue; following the suggestion and discovering that it’s a lifeless finish is a crucial studying expertise in itself. You shouldn’t consider the whole lot you hear, even when it comes from a dependable supply. And a mentor actually has no enterprise producing code, incorrect or in any other case.
I’m extra involved about ChatGPT’s problem in offering recommendation that’s actually insightful, the type of recommendation that you just actually need from a mentor. It is ready to present recommendation while you ask it about particular issues–however that’s not sufficient. A mentor wants to assist a scholar discover issues; a scholar who’s already conscious of the issue is effectively on their means in the direction of fixing it, and will not want the mentor in any respect.
ChatGPT and different language fashions will inevitably enhance, and their capability to behave as a mentor will likely be vital to people who find themselves constructing new sorts of studying experiences. However they haven’t arrived but. In the meanwhile, if you need a mentor, you’re by yourself.
