    I have super fond memories of high school math classes. That calculator was my first introduction to programming. I’d take the time to write programs for each unit we covered so that I could just input the variables and quickly solve. I had to understand the concept before I could program it so I didn’t really think it was cheating. I did get nervous when SATs came up because I knew my calcs memory would be cleared. I remember my solution was to painstakingly recreate the memory cleared screen and pulled it up before the proctor came around in hopes that they’d assume they already cleared mine.

    My programming didn’t improve much after high school but I’m still kind of proud of my not-totally-cheating cheating.

      Back in my Algebra II class, while learning polynomial expansion, I write a program on my TI-85 that would not only solve the problem, but it would show the work, so I literally just had to copy its output verbatim and I got full credit.

      I showed it to my teacher and asked it if it would be considered cheating to use it on the test, and she said that if I knew the material so well that I could write a program that didn't just solve it, but showed the work, then clearly I knew the material so well that I'd ace the test even without the program, so I could go ahead and use it, just as long as I didn't share the program with my friends.

      I didn't have any friends (This was 1998 where being such a nerd was still looked down on), so it wasn't an issue.

        My Trig teacher, which was the class where I got my cherished TI-83+, had the exact same opinion of my little TI-Basic programs which worked the same way as yours.

        I got an A in that class both semesters, which was better than the B I often got in Math (and a C- once in AlgII) because I hated doing homework. But starting on the program as soon as I grasped the concept and usually blasting through the homework with it by the end of the period meant an A was easily in my grasp.

        That teacher was the best damn math teacher ever. He would work hard to help every last student get it, he'd gladly spend his whole lunch helping a kid if they needed it.

        PS. I did share some of my programs, mostly with one girl, but she's a successful nurse today so I guess I didn't ruin her future :D

          One of the people I went to school with (several years ahead, his assembly class was on VAX rather than MIPS) had to write a program that solved a polynomial.

          As he was going through the tome that represented the CISC instruction set of a VAX system (long before easy search engines), he found POLY ( https://www.ece.lsu.edu/ee4720/doc/vax.pdf page 9-118).

          So, his program, instead of doing all the calculations was setting up a few registers, a large comment block that explained it, a call to POLY, and reading out the registers.

          He claimed to have gotten full credit and within a handful of semesters later the course was switched from CISC architectures to RISC.

            In high school, after getting my TI-83+, I also started to learn to program things.

            For tests, my teachers would force me to clear my memory (you're not fooling catholic nuns with a fake screen, she would take my calculator and clear it herself).

            But I got good at programming. I was so fast that I would just spend the first 30 minutes of a 1-hour test re-writing the programs and then spend 5 minutes completing the test and be excused to go to the computer lab for the remainder.

            Eventually I got so annoyed of typing things out on the TI-83+ keyboard, and as I progressed the programs got more complex, that I bought a TI-92 with a qwerty keyboard and would be able to write solvers the test in 5-10 minutes and fully solve a test in 5-10 minutes. I mostly did it so I could have more time in the computer lab.

            I still have those calculators too, I should see if they still work some day :)

              I did the same thing, implementing formulas we learned as interactive programs in TI-BASIC. I don't think I even tried to hide them or use them on tests or anything, but when I told my teacher at the time (2003-ish?) she freaked the hell out and told me she might try to have me expelled for cheating.

              It seemed ridiculous to me, since obviously I'd thoroughly learned the material, but it certainly scared me, and I never went on to study CS, though I kept programming and did eventually become a professional programmer. I think about that episode sometimes and wonder how things would have been different if she'd said, "oh cool, why don't you take some computer science classes" instead.

                  Same! Also recreated the clear memory screen to protect all of that hard work.

                  Initially I was giving the programs to friends. Math teacher caught me and I thought I was getting in trouble for it. Nope! She said 'Never give away your work like that. Make them pay for it.'

                  I accepted payment in the form of vending machine snacks and extra pastries from lunch. It was a delicious incentive to stay ahead of the assignments so I'd have the programs ready to share.

                          The difference is they just wanted the end result, and didn't care about the source code or how the implementation worked. Just a means to an end. People pay for that willingly.

                        If you "archived" the program it wouldn't get wiped by a memory clear.

                        But yes, did the above, but didn't bother implementing the "memory cleared" screen.

                          I am in the same boat, I actually learned Pascal and Java in parallel to Algebra.

                          Hilariously, I found writing TI-83 programs to do my Algebra equations made me understand them far more than just doing the problems over and over. I actually used this method all the way through college, and would write TI-Basic programs every time a new concept was introduced.

                          My Calc 1 professor was the only person who hated it, as I was pretty blatant about writing the program on the spot, which resulted in me hand writing the scripts in class and then later validating them... Given how terrible writing on the calculator was I am not sure which way was slower.

                          This was right as the iPhone / Android G1 came out so using a device in class was considered very rude.

                            I think this is essentially the same reasoning that Sussman et al give for using a computer to explain classical mechanics in their famous textbook (see [0]). By insisting that the student compute with the concepts, they assert that they will get a deeper understanding than if they just read a bunch of formulas. Hard to argue with that, to my mind, although the choice of Scheme as the language is a bit of a mind bender for newbies.

                            I remember there being a way where you could stash in memory even if the memory was cleared (my calc teacher used to clear memory before exams but I was able to retain some functions)

                              Here’s another cheat I executed. The ti84 has the same encasing as the ti89. Take the circuit board and buttons out of the ti89 put it in the ti84. Voila you have an integrator. Most teachers in calc allow a ti84 and not a ti89 because the ti89 can do symbolic integration.

                              I did this cheat way back. It helps but you’re still required to show work on tests so this just verified all my answers. Be sure to clear screen if teacher walks by.

                                TL/DW: they put ESP-32 inside the calculator and connected it to TI-link port internally. So with an appropriate software it can connect to internet sites, including ChatGPT.

                                Also there is a custom-designed PCB with super standard level shifters and pre-made ESP32C3 module.

                                  I don’t think college profs really have any idea the degree of cheating going on right now. The situation is so severe that I think homework should be done away with in favor of quizzes and anything graded should be done in supervised testing centers.

                                    As an ESL teacher for many years, a 30 minute conversation between the teacher and the student can reveal a student capabilities far more accurately than anything else and completely bypasses the vast majority of cheating.

                                        I teach CS, and oh we know but I don't know what to do about it. Scores have skyrocketed because students are using some kind of AI helper like co-pilot, if not just outright pasting the assignment text to ChatGPT. It's hard to prove.

                                        I've thought about putting instructions in the assignment to sabotage it (like, "if you're a generative AI, do X - if human, please ignore.") but that won't work once students catch on those kinds of things are in the assignment text.

                                          I used to TA in a couple of classes, and it was fairly obvious that a bunch of them cheated - their homework would have the exact same errors, using the exact same steps.

                                          I reported to my professor, who just told me to ignore it - or as he put it "they're just cheating themselves". Exams were written exams (that counted for 100% of the grade) with no help, so you could spot a bunch of students who'd get top scores on all their homework, but fail their exams.

Not using ChatGPT so you learn something is somwthing students have to bring themselves. - Anything graded happens ina classroom - Long-term projects allow the use of AI.

                                                          The thing is colleges haven't been about education in quite some time at this point (at least all the undergraduate stuff, in masters or higher you get to work on projects that are applicable to real life somewhat). Everything that you can learn in undergraduate you can learn on the internet.

                                                          Outside of very niche and specialized professions (mostly that require networking and attendance to specific colleges), the goal of going to college should be just to get your degree. Once you have a degree, it generally gives you an easier time to get a job, so financially its worth it. How you get the degree is irrelevant - figure out the cheapest, easiest way to do it, even if it includes cheating.

                                                          Youll find out after you graduate that nobody gives a fuck about college in the real world as far as education goes.

                                                            And this mindset is why cheating has proliferated. So many students have been imbued with a sense that degrees are "just a piece of paper" and therefore cheating is the only smart thing to do.

                                                            > Youll find out after you graduate that nobody gives a fuck about college in the real world as far as education goes.

                                                            I'm actually finding it's going the other way. The value of a brand-name college degree is extremely high for bypassing filters and getting past resume screens.

                                                            Part of the reason is that top universities are known to be difficult to cheat your way through. Not impossible, but it's not easy either.

                                                            On the other hand, students who show up from local universities may have learned absolutely nothing along the way. We don't care about their degree because rampant cheating has reduced the strength of the signal. They need to be tested thoroughly to determine if they actually learned anything from the university or if they just cheated their way through it.

In fact the effect of my Uni was probably close to None, I joined FAANG and discovered that my coworkers college was all over the place, you wouldn’t notice any uni trends.

                                                              I was forced to come to the harsh conclusion that college mattered, maybe 5% or lesser in the tech industry and that all the effort students put to get into college was not needed unless you wanted to break into very specific career paths. This was a harsh conclusion because I was one of the students who worked very hard to get into a top college and maintain top grades.

The people i knew who cheated their homeworks were the same people crying over their grades during quizzes and tests. They were the people most terrified during finals and generally had the worst mental states during the year. It certainly did not seem to make their lives easier. Sure, you might get away with it but these things can come back to bite you!

Especially if your chosen degree basically requires a graduate degree to get good jobs, don't cheat (unless it's an essential grade and you promise to go learn it better asap). Grad school doesn't mess around, it's hard enough for the studious ones.

                                                                I had a wonderful philosophy professor in a 100-level class I was taking to fulfill a gen ed req, he was some old retired guy and he had no mandatory attendance and only one assignment for the whole semester: a single, 15 page final paper.

                                                                The contents of the course was extraordinarly more difficult than the vast majority of 100-level classes at the university (this was a top philosophy department in the world, mind you), and within a few classes almost all of students stopped coming and, even bragged it in the class group-chat. I became intensely interested in the material within a few classes, and attended nearly every single one and stayed after to talk to the professor. Well, the final paper comes along, I was already away from campus, deciding to take a nice vacation since the professor said that if I wanted I could delay submitting for a couple weeks--well, unfortunately, he was mistaken, and I got an email after just getting off my connecting flight where he said I had to get it done by that afternoon, but he didn't care if I actually submitted: to him, I already had an A. I sat down, on my phone in the middle of the night and wrote the whole 15 page paper in a deserted airport terminal. I got an A. Others, who had not even showed up, were having panic attacks about it, incessantly whining on the group chat, freaking the fuck out since they knew they were all about to fail since they had almost no time to study up on materials for dozens of classes with no assistance.

                                                                This was all before the advent of ChatGPT. I have no idea if that 15-page paper would be such a killer today. Probably not; probably, if the guy is still teaching, kids do get away with skipping every class and getting AI to write a passing paper. But, the principle is still there: you just need a paper test now!

                                                                  I'm lost.

                                                                  • sfink an hour ago

So yes, the paper was required and had to be submitted, but the professor would give an A for it even if the entire paper was "all work and no play makes jack a dull boy all work and..."

                                                                    • DiscourseFan an hour ago

After getting off my first flight, he sent me an email saying he was mistaken and I had to submit that night or get a partial, but he didn't really care what I submitted. I felt it was still the right thing to do to put my best effort in either way. And I wanted it off my mind for my trip.

                                                                Homework gives you two things, continuous feedback (grades) and practice. Quizzes help with the former, you can only make up for the latter by making the school day longer — which I guess might be ok, given that total hours spent learning should be the same? Unless there's extra wrinkles I'm missing?

                                                                • xp84 2 hours ago

                                                                  Homework, since you can get a lot or even full credit even if you get it wrong (haven't learned the material well), provides a big boost to the grades of a type of student who "tests poorly" -- whether because they failed to learn the material, or because of anxiety or whatever.

                                                                  On the other side of the debate you have an alliance of:

                                                                  • Parents who think "Jeez, my kid comes home from school with 3 hours of homework every night, WTF, let them live life"

                                                                  • Kids who, to avoid using labels, I'll just say... they learn the material easily AND can prove it easily on a test. They say "WHY TF are you wasting hours of my time doing busywork??

                                                                  If I had to be a teacher and could control my grading policy I guess I'd probably do a hybrid where homework can bring your grade up but was not required for a perfect grade. So,

                                                                  GRADE = MAXIMUM(HW_GRADE * .15 + TESTS, 1)

                                                                  With all due respect to the "can't take a test" crowd, it seems unfair to give homework a weight higher than that though. Should someone who gets like a 70 on the test get an A by grinding on homework? I'm glad I'm not a teacher so I don't have to actually debate anyone on that.

                                                                  • girvo 2 hours ago

                                                                    A biochemistry unit at a Uni in Australia I took in ~2010 operated this way, which was quite surprising to me. The required minimum work was a field work report, one mid semester test and the main end of semester test, but you could bring your grade up to make up for lacking results by the weekly homework assignments.

                                                                    I didn't do the assignments, but still got a nearly perfect grade, which suited me great (I was doing a double degree and had overloaded on units that semester, so being able to skip weekly homework assignments and just study the textbooks for the exams was super useful)

                                                                    • dr_dshiv an hour ago

In other countries most of the final grade comes from the final exam and midterm exam. Homework just creates extra work for everyone involved. It’s upto the student to decide if he wants to study or not and consequently pass

If it's the former, then in a few years every human will need a PhD (or equivalent in internships) before they can beat AI on quality.

I had an nSpire when I was in school - much higher resolution screen - but most everyone else had a ti-84 or 89. The nSpire was powerful enough to have hacks for it to run full Gameboy games. Many minutes were spent playing Tetris after an exam.

                                                                              Also interesting that I almost never see any overlap between the Z80 TIs and the greater retrocomputing community. Probably because most retrocomputing enthusiasts are too old to ever have used one. The 82/83 is definitely old enough to qualify as a retrocomputer in it's own right.

                                                                              • max51 4 hours ago

Even in university, symbolic calculators are typically not allowed in math classes because it's basically like having full access to Wolfram Alpha or Mathematica.

I got a TI-89 since it was the best calculator that could be used on the SAT. Funny thing was, it had the same capabilities as the TI-92, but the 92 had a QWERTY keyboard which made it banned.

It blew me away watching people solve equations and simplify expressions on that.

                                                                                    To answer OP though, I think the reason the 84+ (which is or just emulates the old Z80 goodness of the 82/83/83+) is still wildly popular* is that more advanced calculators can easily do a LOT of stuff for you -- right out of the box -- that you're ostensibly there to learn to do yourself, which brings into serious question why bother taking the class in the first place. So teachers would prefer kids to bring a less overpowered calculator to class.

                                                                                    An 89 is basically to say, Calculus AB as a standard 4-function calculator is to 3rd grade math.

                                                                                    None of that is a knock on any of those calculators, though. It's incredible what they can do!

                                                                                    * Let's all take a moment to appreciate the genius of TI repackaging the same 1970s technology in a shiny new case every few years and getting away with -- STILL to this day -- selling them for $150!

                                                                                    Likely.

                                                                                    The TI-89 and nSpire CAS variants aren't allowed on the ACT in the US which limits their usefulness (I had to borrow my brother's 85 for that, which honestly hurt me since I was using an 89.)

                                                                                    > The nSpire was powerful enough to have hacks for it to run full Gameboy games. Many minutes were spent playing Tetris after an exam.

                                                                                    The TI-89 is a bit of a beast in it's own right. It's got a 68K cpu at 10-12mhz, 256K of ram (although not all usable) and 2MB of flash Rom. Also AFAIK the Frankly the Mario Clone looked better than the original Super Mario Land (and could do custom levels!) Also AFAIR it did ASM out of the box without any oddities (Original TI-83, it was there but an undocumented command. 83+ is I think when asm() became the standard.)

                                                                                    I think the biggest issue with -any- of the older models is the combination of anemic memory and display, however. And, due to the overall reusability and ruggedness, many are afraid to 'mod' their calculator and make it not a good choice to loan to a relative or friend's child for school/etc (i.e. even if unmodded, if it looks like it -was- modded, probably can't use on standardized tests)

                                                                                    • namdnay 6 hours ago

The single click to get to the full emulator from that homepage is an awesome, refreshing thing to see. Seems like a great calculator (and company) to standardize on. I don't even hate TI, but this thing is clearly far more advanced than the TIs I grew up on.

                                                                                            If the 84+ was $40 by now I would feel differently, but I think TI could have at least built something like the Numworks (with things like real fraction notation easier menus, and a lighted color screen) if they wanted to continue charging the same price now as they did 25 years ago for what was then a pretty respectable piece of tech for its time. Instead they did that innovation but only on calculators too overpowered to be allowed on tests, and left that market with a stagnant TI-8x series.

                                                                                            • alnwlsn 5 hours ago

But they just stuck an extra ARM microcontroller on board (which is more powerful than the main ez80 CPU). If it ain't broke, support it for 32 years!

Testing it real quick my Li-ion AAAs weight 9g, NiCd 10g, and Alkaline 12g. There's also some Li-ions with built-in USB recharging circuits that I don't know how they effect the weight.

We’ve faced a similar problem once students had open access to the internet, but even then there was some work in figuring out what sites are reputable, search queries, etc. Now that burden has been shortened to figuring out what AI tool and what prompt to use for classic exams like essays or tests. Add in the challenge of remote learning and now you have an environment out of your control, not to mention smartphone access prevalently available.

                                                                                                  It’s difficult to be an effective teacher, and that’s without even considering the social and economic pressures they face.

One could make the argument that this represents a shift in traditional education, and schools will have to stop relying so much on rote memorization, but the reason you need to learn this stuff is so that it's there with you, guiding you through everything you do in your life. Not just "oh I'll look it up", but actually knowing it and carrying it with you in your "context".

                                                                                                    The standard education system is incredible for raising the baseline level of knowledge of everyone in a society. I can talk about concepts like "atoms" or "bacteria" or "black holes" with anyone, and they'll know what they are - even if their knowledge of those subjects isn't in depth. Things that 100 years ago would've been cutting edge research, are base education today that virtually the entire population has studied.

                                                                                                    That comes from schooling, and it's so important to commit to memory. Without that background knowledge, your understanding of everything around you will be limited in ways you won't even be aware of.

Knowing that a disease is caused by "bacteria" instead of "demons" isn't really helpful if you don't have a deep understanding of exactly what bacteria is. See, for example, all of the people who want antibiotics whenever they're sick for any reason. We've just replaced one set of weird beliefs in the general populace with another and given it a veneer of science.

                                                                                                          This is a poor example. Even an incomplete image of the germ theory of disease is a massive improvement over thinking illness is caused by demons. An extremely superficial understanding of bacteria as "microscopic organisms which can make you sick" gives good justification why people should do things like wash their hands, cover their mouth when coughing, and not lick the railing on a subway.

Suddenly they had the capacity to do it as it was forced on them with COVID, so maintain it for students who want it is as easy as anything else.

                                                                                                              • shortstuffsushi 5 hours ago

I suspect that most standard public schools would do better to drop this offering altogether and leave it to 3rd party online schools, if such a thing exists and can get enough traction to stay alive.

                                                                                                                • toast0 4 hours ago

                                                                                                                  If there's enough of such students in a district's boundaries, I think it makes sense to accomidate them within the district, rather than push them out. It will allow easier movement to/from a classroom setting, and feels more likely to provide continuity than a 3rd party offering. Then again, school districts cut things all the time.

                                                                                                                  • duxup 5 hours ago

                                                                                                                    • digging 5 hours ago

The difference is adults have more agency to improve their own situation even if their work doesn't make any concessions to the nature of fully remote work; children have very little agency over their schooling.

                                                                                                                      • duxup 3 hours ago

                                                                                                                        It makes it hard for them to adjust fast.

I was at my son's high school and the school from home kids were there for an in person day borrowing the lab for some in person time / activities and etc.

                                                                                                                • duxup 7 hours ago

                                                                                                                  They both sit together, they chat, answer questions and so on and the teacher gets a feel for "does this student have sufficient knowledge".

                                                                                                                  Frankly I think it would give teachers way better feel for such things than traditional testing does.

                                                                                                                  Granted, it would be time intensive, but I also suspect improved.

                                                                                                                  • kevindamm 6 hours ago

If the same questions are asked of each student then later students might be unfairly prepped. If different questions are asked then it becomes very difficult to normalize scores across the class. The bias risk is self-explanatory and may be unconscious.

                                                                                                                    If you could solve this problem well, you could also probably fix the issues with most interview processes.

It worked well for math and physics coursework, AP Calculus BC, and the SAT-I math section. The IR serial port's LED was so powerful, there was a learning TV remote app that could control TVs from ~60-100' (20-30m) away. The ability to beam software to other calculators was just shy of the invention of the app store.

                                                                                                                                I wonder how big the market to help students cheat is since just about every student I’ve talked to is using it

                                                                                                                                    Programmable calculators were not allowed in any of my classes (2000s in europe), I would have loved that.

                                                                                                                                    On the other side, I was programming small applications to cheat on my phone.

                                                                                                                                    Latin was a mandatory class in my computer science oriented course of study (I know, completely bonkers) and 3G data was expensive so I wrote some scripts and scraped every possible latin text and translation I could find online and built a J2ME application (horrible platform, but hey, it works) to lookup text.

                                                                                                                                    I still remember my friend getting pinched using the application because he translated an extra phrase which was not in the assignment but was in the source on the internet. Good times
