The online calculator is free for anyone and can be used on desktop computers, laptops, tablets, and smartphones. “They innovated this calculator through really almost a ‘mom and pop'-type shop,” said Alpert. He officially launched the company in 2011. The emergence of Desmos, and particularly in light of this partnership with a large-scale test company, could be shaping up to become a computer-age David and Goliath story.Įli Luberoff began developing the software behind Desmos in 2007 while on leave from Yale University, where he majored in math and physics. “The layout is more intuitive” with Desmos, said Alpert. The Smarter Balanced exam has always had an embedded calculator known as an equation editor that performed basic functions, but some educators complained it was tough to use (though not an insurmountable challenge). (In fact, anyone reading this who went to middle or high school in the 1990s or later is likely to have used one of the clunky devices at some point.) It’s true that one company-Texas Instruments-has long had a lock on the school graphing calculator business. That required an online calculator that Smarter Balanced could embed directly into the test. Smarter Balanced wanted students to have an alternative to expensive handheld graphing calculators for students taking its middle and high school math assessments. Students who could not afford these expensive calculators were left with limited options, as were the many schools who couldn’t afford to purchase the calculators on their students’ behalf. Until recently, high school and college math students have had to rely almost exclusively on expensive, handheld graphing calculators costing more than $100. But a joint press release frames the decision as targeting economic inequalities.
