For someone who has never been particularly fond of mathematics, I have purchased an astonishing number of Texas Instruments calculators—at least four or five—starting in high school and carrying through to college, and even during a surprising phase as a math tutor. Losing them or having them stolen became a pattern, which means I’d certainly appreciate a refund for that wasted $500. Here’s a thought to contemplate on your TI-83: had I invested that money in a mutual fund back in 1988, it would have flourished significantly. Honestly, I don’t need a calculator to figure that out.
This brings me to the pressing question: why do we continue to buy TI-83 calculators? We used them in high school, and now we’re preparing to purchase them for our children two decades later. With instant access to online tools that can calculate “compound interest” for free, why should we fork out $140 for outdated technology? In an era where computers can fit into tiny spaces, why are students still lugging around devices the size of a thick cookbook? In essence, how does Texas Instruments maintain such a stronghold on the graphing calculator market?
The truth is, they practically have a monopoly. Jack Thompson IV, writing for Mic, explains, “Texas Instruments has an overwhelming presence in the realm of high school mathematics. The American education system is heavily reliant on TI calculators, which have become embedded in the fabric of math instruction in the U.S.” He also notes that textbooks by major publishers like Pearson feature illustrations of TI calculators, making it challenging to transition students to newer technologies.
However, the strongest tether keeping us—and our children—attached to Texas Instruments is standardized testing. For example, the SAT only permits calculators from a specific approved list. While this is presumably to curb cheating and internet access, I can attest that students managed to program their TI-83s with formulas and notes during my tutoring sessions.
Moreover, Smith highlights that TI employs a cadre of educators trained to teach using their calculators, acting as advocates for the brand. The company even sets up large booths at educational conferences. In the 2013–2014 academic year, Texas Instruments accounted for 93% of all graphing calculators sold in the U.S. With production costs between $15 to $20, they enjoy a profit margin exceeding 50%, making these calculators one of their most lucrative products.
It’s worth mentioning that alternative calculators exist at a fraction of the price; for instance, Casio offers one for around $50. A math teacher from Pennsylvania remarked, “I tell students the difference between TI and Casio is just marketing.”
This situation isn’t as dire for those who can easily afford the TI calculator. But it poses a significant challenge for families struggling to meet basic needs. An outdated, bulky, and unnecessary piece of equipment that students are required to buy for math classes and standardized tests? I might be tempted to encourage my kids to manage with a less expensive option, which could further complicate their already challenging math experience. As Smith notes, “The way Texas Instruments collaborates with testing companies, educational standards boards, and compliant educators reinforces the achievement gap between affluent students and their less privileged peers.”
On a brighter note, there are now free apps that are more intuitive and gaining traction in classrooms. However, I personally believe I grasped math concepts better when I worked through problems by hand with pencil and paper. In my teaching experience, I found that students thrived in the same environment. When the time comes, I’ll be assisting my own children with No. 2 pencils and graph paper. If they want to experience authentic ’80s technology, they can listen to my old Sony Walkman.
In conclusion, the TI-83 calculator still reigns supreme in education, largely due to the intertwined interests of standardized testing and traditional teaching methods. Despite the emergence of cheaper and more efficient alternatives, the grip of Texas Instruments on the market appears poised to continue.
