"The National Council of Teachers of Mathematics (NCTM), the dominant US professional organization for math teachers, has the use of technology in classrooms as a main pathway to improving learning. The NCTM's Principles to Actions says, on page 5: 'An excellent mathematics program integrates the use of mathematical tools and technology as essential resources to help students learn and make sense of mathematical ideas, reason mathematically, and communicate their mathematical thinking.'

So one way to find out what the vanguard of K-12 mathematics teachers are doing in their classrooms -- and are planning to do -- is to look at the list of presentations given at the huge annual NCTM meeting. How many of those presentations are about, or at least make reference to, technology?

Ihor Charischak, president of the NCTM-affiliated Council for Technology in Math Education, has done just that. He released his findings in a recent blogpost.

According to Charischak, at the NCTM Annual Meeting to be held in Boston, MA, next April, there will be 733 sessions. He combed through them and identified just 97 that highlight technology in some form. At 13.2 percent, not only is that low, it indicates a continuing drop in interest in educational technology. At last year's NCTM Meeting in New Orleans, 21 percent of the sessions were technology-oriented, a year earlier, in 2013 in Denver, 28 percent of the sessions had a technology theme, and the year before, in Philadelphia, there were 38 percent tech sessions, an all-time record.

Not only is there relatively little evidence of teacher interest in incorporating any kind of technology in the classroom, but the trend is clearly down. Moreover, what technology interest Charischak could identify was hardly in new technologies: It was predominantly the use of handheld calculators and Computer Algebra Systems (like Mathematica), which where highlighted in the title or abstract of just 15 sessions.

What these data show is that, to date, practically all that much-hyped edtech funding has had virtually no direct impact on what goes on in the K-12 math classroom. Overall, K-12 math teachers are not incorporating new technology in their teaching."Dr. Devlin finishes with this:

"Genuinely revolutionizing K-12 education within a decade requires a transformative, national, public-private initiative, perhaps reminiscent of, but much less expensive than, the NASA Apollo Project to put a man on the Moon.

How badly do we want 21st-century-relevant, first-class education for the nation's children?"
