In the same way that publishers take advantage of students’ captivity when it comes to needing textbooks, Texas Instruments does the same. Here’s a fantastic article on the subject that quotes a PA HS teacher who says “But you feel dirty, because you’re telling parents they need to buy a device, and I know I can teach without it.”
More from the article:
“There’s no reason they should cost so much, and it’s shutting out students who can’t afford them. Just this past week, Amazon started selling Internet-capable Kindle tablets for $50 each. But a new TI-84 still runs a retail price of $100, and classrooms that use TI-Nspires (the newest addition to the TI line) are shelling out $140 a pop — about the price of a brand new Chromebook. All for a calculator that is older than the .MP3 file extension.”
Like for-profit textbooks, this is a battle that HS and college faculty need to fight. There is no reason that TI should continue to cash in on our discipline like this, especially with an outdated technology for which they are overcharging. As the article says: use Desmos instead. Or Geogebra, of course.
