For someone who isn’t particularly fond of math, I’ve owned far too many Texas Instruments calculators—about four or five, starting from high school and extending through college, and even during a brief stint as a math tutor. I seemed to purchase a new one every couple of years, either losing them or having them stolen. At this point, I’d love to get that money back. If I took that $500 I spent on calculators and invested it in a mutual fund back in 1988, I’d be looking at quite a hefty return. But honestly, I don’t need a calculator to tell me that!
So, this raises the question: why are we still investing in TI-83 calculators? We bought them as teens, and now we’re preparing to buy them for our kids—two decades later. With just a quick Google search, I can find “compound interest” calculations for free; why pay $140 for outdated tech? In an age where computers can fit in your pocket, why are students still lugging around a device the size of a cookbook? Essentially, why does Texas Instruments dominate the graphing calculator market?
It turns out they really do have a stronghold on this niche. As Jack Miller reports for a reputable outlet, Texas Instruments has established a significant monopoly in high school mathematics. Their calculators have become so entrenched in the American education system that it’s hard to imagine moving to newer technologies. Textbooks from major publishers like Pearson even include illustrations of TI calculators, making it challenging for educators to transition students to more modern options.
But the real kicker is standardized testing. Schools often restrict calculator use to specific approved models during exams like the SATs. This is likely intended to minimize cheating, but let me tell you, I saw plenty of students programming their TI-83s with formulas and notes while tutoring. Miller also mentions that TI employs a network of teachers trained to use their calculators, who essentially promote the brand at educational conferences. It’s a lucrative arrangement that borders on monopolistic. In the 2013–2014 school year, Texas Instruments sold a staggering 93% of all graphing calculators in the U.S. They produce these calculators for about $15 to $20 and enjoy over a 50% profit margin, making them one of the company’s most profitable products.
Of course, there are cheaper alternatives. For instance, Casio offers graphing calculators for around $50. One math teacher in Pennsylvania told Miller, “The difference between TI and Casio? Marketing.” While this isn’t a major issue for families who can afford the pricier option, it presents challenges for those struggling to make ends meet. Parents are forced to purchase a bulky, outdated device that students are required to have for math classes and standardized tests. One might be tempted to encourage their kids to make do with a less expensive calculator, which could further complicate their math education. Miller points out that the way Texas Instruments collaborates with testing organizations and educators only exacerbates the achievement gap between affluent students and their peers.
On a brighter note, there are free apps that are gaining traction in classrooms, offering more user-friendly options. Personally, I found that I learned math better when I worked through problems by hand, and my students seemed to thrive under similar circumstances. When the time comes, I plan to help my children with No. 2 pencils and graph paper. If they want to relive the retro vibe of the ’80s, they can always pop a cassette into my Sony Walkman.
In conclusion, while the TI-83 calculator still reigns supreme in schools, there are emerging alternatives and resources available for students and parents.
