Texas Instruments' New Calculator Will Run Programs Written in Python (dallasnews.com) 126

Posted by EditorDavid from the machine-languages dept.
"Dallas-based Texas Instruments' latest generation of calculators is getting a modern-day update with the addition of programming language Python," reports the Dallas Morning News: The goal is to expand students' ability to explore science, technology, engineering and math through the device that's all-but-required in the nation's high schools and colleges...

Though most of the company's $14 billion in annual revenue comes from semiconductors, its graphing calculator remains its most recognized consumer product. This latest TI-84 model, priced between $120 to $160 depending on the retailer, was made to accommodate the increasing importance of programming in the modern world.
Judging by photos in their press release, an "alpha" key maps the calculator's keys to the letters of the alphabet (indicated with yellow letters above each key). One page on its web site also mentions "Menu selections" that "help students with discovery and syntax." (And the site confirms the calculator will "display expressions, symbols and fractions just as you write them.")

There's even a file manager that "gives quick access to Python programs you have saved on your calculator. From here, you can create, edit, run and manage your files." And one page also mentions something called TI Connect CE software application, which "connects your computer and graphing calculator so they can talk to each other. Use it to transfer data, update your operating system, download calculator software applications or take screenshots of your graphing calculator."

I'm sure Slashdot's readers have some fond memories of their first calculator. But these new models have a full-color screen and a rechargeable battery that can last up to a month on a single charge. And Texas Instruments seems to think they could even replace computers in the classroom. "By adding Python to the calculators many students are already familiar with and use in class, we are making programming more accessible and approachable for all students," their press release argues, "eliminating the need for teachers to reserve separate computer labs to teach these important skills.

            For calculators used on standardized tests, "a dual-purpose keyboard that is LITERALLY a calculator keyboard" is a requirement. The College Board bans QWERTY keyboards from the SAT.

            Many graphing calculators have wired networking through a USB port or (in older devices) a serial port through a 2.5 mm TRS jack. As for wireless networking, for calculators used on standardized tests, "absolutely no networking to upload their programs to" the device of another student taking the test is a plus.

      • You could write the programs on a computer and then transfer them to the calculator over USB (or Serial) like we did 25 years ago. Except back then we used assembly or basic. There's no reason why you would actually have to enter the program directly on the device you plan to run it on.

          A calculator is a much more specific tool than a smartphone. While there are good apps for smartphones that give you all the functions of these calculators (and I am not thinking of "emulators" that mimic a specific calculator model, but rather real math apps like Geogebra, Desmos, etc) the input is awkward. My students have access to calculators, computers and smartphones in my math classes and without a doubt most stretch for the calculator for most calculations. For some, Geogebra is superior.

          So learning to use the array of tools available to them is not a bad thing.

          But yes, more and more are moving away from them and exclusively using computers. Still, I have had more than one student whose computer crashed during a test or wouldn't start, whereas a calculator like these are way more robust. If anything would happen, you press the reset button on the back with the tip of your pen and a few seconds later you are back in the game. They are also a magnitude or two cheaper than a computer.

              Where I teach, computer with math software is equivalent to calculator, so at tests, if you are allowed to have one you can use the other. I have some students that absolutely prefer Geogebra when graphing (I do too!) especially when you can adhere points to curves and drag them around and if you attach a tangent to the curve it follows.

              But for some types of calculations most prefer a calculator since it is easier to enter calculations on and as I mentioned, they are a lot more reliable. I had one student coming in for a test during Covid, since she hadn't been to school for months and not connected to our trusted network, her computer automatically went into update mode upon connecting and spending over 30 minutes out of the 2 hour test to update the OS. Fortunately this was not a math exam, so she got a paper version of the test and I allowed her extra time to transfer the answers into the electronic test system so I had all the answers collected there. But I have experienced crashes during math tests and that stresses some out, so having the calculator next to you is a good safety net.

              Calculator apps on the phones are really competent. Geogebra on my smartphone have all the functions of the desktop or cloud version. But the input and limited screen size is an issue. Also, there are soooo many apps and many of them costs, so it can be tough to find one that you like. Also, smartphones are not allowed during test unless you use the lockdown function on Geogebra, but generally we don't use them. Our computers have a test mode that restricts their use (in theory, a few years ago some of our students found a hole in the system and wanted help from the teachers to replicate it. When they succeded they reported it and got a cash reward from the company supplying the software to the schools).

              • That is why everyone with a brain has automatic updates disabled.

                • The students don't get to do that since that would be a huge security risk in the long run, the policies are set by the system administrators and considering that a school can only hire that many of them they need to set strict policies so that the system is manageable. Our school is one of the lucky ones, it is large enough to actually have REAL IT staff on site every day of the week. Smaller schools don't have that luxury.

About one fifth of the class have the TI-Nspire CX CAS. Those that do not have this are allowed to use GeoGebra instead to get access to CAS functions.

      When we teachers put together tests we often have one part that the students solve without any calculators, followed by a part with calculators. This is to comply with the national curriculum which have parts that say that the students must be able to show problem solving with and without calculators and other digital tools (which may include programming).

          It teaches the students that not all problems have "clean" algebraic solutions and more importantly, it teaches them that they will have to learn how to identify which problem they can get an exact answer for and what problems they will have to do with other kinds of solutions (using numerical methods for example). Knowing your own limitations and what machines can do for you is learning for life.

          When you come across a problem in real life, there isn't a solutions guide in the back of the book or hints in the problem. So giving these kinds of problems to the students prepare them for the more varied problems in real life.

              You are welcome.

              It is hard to impart that kind of knowledge. When constructing tests we are supposed to measure their skills in different areas, and when it comes to problem solving, the last part is to evaluate the answer and see if it is a reasonable answer. But creating good tests is hard and sometimes you realize that you haven't succeeded when you see what the students hands in. Given the number of dimensions you are supposed to test on it is hard to cram everything you want into one test.

              But I know that different countries have different philosophies. I have a colleague who attended an international conference for teachers and got into a (heated) discussion with a teacher from the US that claimed that tests with multiple choice questions are superior for determining the level of understanding a student exhibits (and apparently only used multiple choice for his/her tests).

              I hope this teacher was an outlier and NOT representative of the US school system. Nothing wrong with multiple choice questions, they are the easiest to grade, by far. I can even let a machine instantly do the grading for me! (Yay, I saved a few late nights there.) For evaluating subtle nuyances in knowledge? Please... I would like to see some educational research study to back up that claim. Until then I call BS on it.

              During my studies in mathematics didactics we were given real world answers from students and supposed to look at them to try to learn what the students had grasped an not, and discuss it in class. It was really interesting and useful. By reading between the lines and trying to get into the mindset of the student you could learn a lot about the difficulties they face and how we as teachers can help them.

      They're hardly spoilt if they have to program in Python.

  • I've always liked TI calculators in theory but I have to say they just don't worry about what I think is important; being able to reliably read the display and enter keystrokes. This is unfortunate, because their modern calculators aren't terrible in terms of functions - my kids have been using the TI-36X Pro that were required for them to buy for school math which have decent functionality but with screens that have to be held at an unnatural angle to read and with keys that are simply mushy.

    This is why

  • TI calculators are toy-trash that only exist due to lobbying - they are nothing really special. You have them for the same reason that you have high-fructose corn syrup and bioethanol - political lobbying. This calculator has zero reason to exist because any app is better and cheaper. This is about getting schools to force kids to have to buy something they don't need.

    • I use Casio calcs also.
      Besides the graphing one I have, though I use computer graphing programs now, I also have some separate when I need to finagle a few numbers away from the computer.
      Of course I can use my sliderule also.
      And no I am not an old fogie.
      The slide rule is what my father used in the 60's and 70's.

  • And what happens when a Python gets revved again? This is a manifestation of the It Goes to 11 [youtu.be] principle. What's next, an email client?

    • The whole crapfest that was Python2 vs Python3 was if you relied on a bunch of different libraries and some of those libraries were 3 and some were still 2.
      I doubt the standard use case supports downloading external libraries - I mean there's no wifi or bluetooth, so that wont be a problem here.

      Don't expect this to be a full fledged programming machine, just a nice introduction to "math focused programming" machine.
      (all that aside, unless they were insane it would be Python3)

      • You are correct, they use Python with some proprietary libraries to access the rest of the calculator and restrictions on use (limit on list lengths for example), so it is like a subset of regular Python. Previously they used something more like to Basic, so they are trying to keep up with the times I guess.

        For those interested, the reference guide [ti.com] is available as PDF.

      Probably a variant of PicroPython, hence Python 3. Sort of.

  • I taught myself z80 assembly with a Ti-83. These were/are fun little kit.
  • I have a now vintage PC-E500, have had a PC-1500. Someday, I want a PC-1600, but they are quite rare.
  • Can't you just get an app for that?
  • Nope but someone will want to mine crypto with them. This is actually something I would buy and use personally. Looks like an excellent tool.

      Lol, let them try. If you see a graph plotting you understand that their strength is not in their speed. But as a proof of concept, why not. I just wonder how you are going to communicate with the rest of the crypto network. Need some serious hardware hacking skillz to pull that off :-)

      Yes, I think it is. I got a TI-85 decades ago, and used it extensively in my engineering studies. When starting as a teacher a few years ago I started using it again, and it is still the amazing calculator it was back then. B

  • It is beyond me how a school/high school can demand a certain kind/brand of a calculator, and that this is is even legal.

      They don't, so your comment is both incorrect and irrelevant. They might say "graphing calculators allowed", but they don't say "only this specific brand/model".

    • It is not brand specific in most cases. The TI series is just really good and becomes the standard, as it meets all the requirements.

  • Only reason I use a HP 35s: Good, tactile keys. Seems basically no other calculator has good keys these days.
