Which make me to check and... a TI-89 is still over $100.
- Igglyboo 11y agoThe product doesn't need updating and they have no competition so why lower the prices? If you want something newer with more power and more features they also have the Nspire line of calculators but the TI-89/TI-83 basically the staple calculator for highschool math.
- rz2k 11y ago> they have no competitors That is exactly why it would rub people the wrong way on a site where people are interested in entrepreneurship and also in disruption. Being approved by standardized testing institutions becomes a barrier to entry and a means for rent seeking. Of course there could be far better calculators for lesser cost that aid learning better, and more clearly reflected the types of tools that should be the default quality for practitioners in the real world. Compare the HP-12c in finance. It's extremely well-designed and optimized for a lot of patterns, and it even has a moderately steep learning curve that seems to enamor it to its users, yet it is absurd to argue that absent certification as an approved calculator for the CFA that there would not be be even better handheld calculators used more often that people spent time to learn. The TIbcalculator doesn't address either demand that goals of high school mathematics should address. It doesn't expose students to the state of the art, and despite its constrained capability it is costly enough to shrink the talent pool of high school students who get to take the tests that show off their aptitude and achievement.
- thaumasiotes 11y agoA calculator is necessary for the AP calculus test; calculators are allowed, but not necessary, for the SAT.
- zhte415 11y agoGenuine question: It is nearly 20 years since I was in post-secondary education: Why would calculators be needed for a calculus test?
- thaumasiotes 11y agoTo calculate certain definite integrals that you wouldn't expect a person to do by hand.
- zokier 11y agoI don't think the problem are standardized test institutions; for example Collegeboard, who administer AP and SAT tests, allow wide range of calculators from five manufacturers. Sure, they might not be the only game in town, but afaik they are the most influential one. I think the problem is far closer to the grassroots, down to individual teachers taking the easier well trodden road of TI monoculture for various reasons ranging from ignorance, busyness or fear.
- throwaway7767 11y ago> The product doesn't need updating and they have no competition so why lower the prices? They absolutely do have competition, see for example the HP Prime, which is far superior (IMHO) to any calculator TI puts out. The issue is that TI has a very effective market lock-in, so they don't have any incentive to innovate. They know students in the US will still buy their calculators because they won't be allowed to take the test if they don't
- detaro 11y agoSo they don't have competition for a giant part of the market.
- kristopolous 11y agoon ebay it can go for $65. I got mine in early June for $40. Supply and demand for school supplies are about as predictable as desk fans and space heaters.
- mrebus 11y agoIt's crazy to think I bought my ti-89 in 2000 it was 250ish. It ran on a 68000 that was already old AF, and I love that calculator. Why was it so expensive. At the time other graphing calculators existed but no other company had a comparable calculator(at least to me)
- gaius 11y agoI am an HP guy rather than TI but if they are of comparable build quality, you could still be using it 30 years later. Imagine that with a smartphone.
