“The batteries are even not rechargeable like a cell phone.” He estimated that a TI-84 Plus cost $15-$20 to manufacture and has a profit margin of over 50% for TI. Smarter Balanced Executive Director Tony Alpert also said the online tool will be accessible for students who are blind and visually impaired - among other abilities, the new calculator can pair with a pad that renders numbers in Braille as students use the device.īarclays analyst Blayne Curtis in 2014 told The Washington Post that the TI-84 Plus was a kind of interesting relic: “Plastic case, small black and white screen, two semiconductor chips,” he said. With about 3 million students taking the tests, the cost per student for the upcoming fiscal year works out to just five cents per student.
Luberoff wouldn’t say how much it charges, but Smarter Balanced said its three-year contract with Desmos runs to just over $459,000. While Desmos’ device is free for teachers and students, the company charges textbook publishers and test developers for its cost. The Desmos tool, he predicted, will cost schools “orders of magnitude” less than the typical TI device. “I can’t think of a good excuse for the fact that the price hasn’t come down,” he said. Luberoff acknowledged that using the same tool on a test that a student uses in class, for instance, can be familiar and helpful, but he said the TI-84's high cost - around $100 on Amazon - has “started to become a pretty big problem,” worsening inequality in schools. Peter Balyta, president of TI Education Technology and a former math teacher, defended the purchases, saying a TI calculator “is a one-time investment in a student’s future, taking students through math and science classes from middle school through high school and into college and career.” He said TI’s technology is evolving, but that models like the TI-84 Plus come with “only the features that students need in the classroom, without the many distractions that come with smartphones, tablets and internet access.” Yet students taking advanced math tests have been forced to buy one.
The TI-84 Plus, he said, was “an amazing device when it premiered,” but not so much anymore. “It’s just incredible to us that this machine has defied all of the advances that we’ve seen in the rest of technology,” Desmos CEO Eli Luberoff told USA TODAY. As a result, functionality for models like the TI-83 Plus and TI-84 Plus hasn’t significantly increased in pace with virtually all other technology - and prices haven’t come down sharply as they have for laptop computers, digital cameras and smartphones. Virgin Islands and the Bureau of Indian Education.ĭesmos officials say Texas Instruments (TI), which has sold more than 75 million graphing calculators worldwide since 1990, has enjoyed a “near market monopoly” on the devices for more than three decades, thanks to long-standing strategic partnerships with textbook publishers, statewide testing companies and college entrance exam makers.
Smarter Balanced administers online tests in 15 states, the U.S. Students in the College Board’s “SpringBoard” math program are already using it, the company said. The tool, developed by San Francisco-based Desmos, is being tested by students this spring, with plans to use it widely in classrooms in the fall. The Smarter Balanced Assessment Consortium was set to announce on Monday that it will embed the online calculator into math tests that millions of students use. Young people these days live most of their lives online, so why shouldn’t they be plotting graphs and performing advanced calculations there as well?įor the first time this spring, students taking basic skills tests nationwide will be using a free, online, embedded graphing calculator that its developer says may finally bring the tool into the 21st century.
