Enter Desmos, a San Francisco-based company that offers a free online version of TIâ€™s graphing calculator. Users across 146 countries, most of them teachers or students, are currently logging 300,000 hours a day on the platformâ€”and today, Desmos announced a major partnership with testing consortium Smarter Balanced, which administers academic exams in 15 US states. Beginning this spring, students in those areas will use the online tool in math classrooms and on statewide performance assessments.
When students take their year-end assessment in 15 states, they’ll see the same free calculator they’ve been using at school and at home the rest of the year. That assessment will more closely reflect what they know, rather than what they were able to express through unfamiliar or costly technology.
USA Today has the reaction quote from Texas Instruments president Peter Balyta:
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 studentâ€™s future, taking students through math and science classes from middle school through high school and into college and career.” He said TIâ€™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.”
This is interesting. In a world where more and more assessments are delivered digitally (and pre-loaded with digital calculators) the sales pitch for hardware calculators is their lack of features, rather than their abundance.
There is clearly a market today for a calculator that lacks internet access. Around 20% of teachers in my survey said they wouldn’t let students use mobile devices on exams for reasons of “test security” and another 10% cited “distraction.”
Open, interesting questions:
- Are those figures trending upwards or downwards?
- Will schools and parents continue to pay Texas Instruments an estimated 50% profit margin for more test security and fewer distractions?
- How do math coaches and instructional technologists help teachers harness the advantages of the internet while also managing concerns about security and distraction?
2017 May 12. Peter Balyta makes a longer case for hardware calculators, one which won’t surprise anyone who has followed this discussion. He mentions (1) lower cost, (2) fewer distractions, (3) greater test security, (4) more features, and (5) availability on tests.
