C12 Interview Ilan Samson QAMA Calculator

Calculators are designed to eliminate the need for repetitive, tedious arithmetic, leaving time to actually think about the math. When used correctly in the classroom, modern graphing calculators can do wonders for visualization, simulation, and encouraging that critical thought that we’re all after.

They were supposed to eliminate the tedium and simple mistakes that plague many calculations but instead have become the go-to device for any math problem. Worse, students frequently lack the mathematical savvy to know when the answer output by the calculator doesn’t make sense. Estimation, it would seem, is a lost art.

Enter QAMA, truly one of the coolest, most thoughtful, welcome bits of ed tech to hit math classrooms in a very long time. Created by Ilan Samson, a retired physicist and serial inventor, to address exactly the problems I described above, the QAMA calculator forces students to provide a reasonable estimate for their answer before it will output the exact answer.

Ilan covered much more complex functionality later in our interview (I’m afraid that when you stick a couple of math geeks together, we can get a bit long-winded, so I didn’t include the entire interview here); however, the concept remains the same. Force students to demonstrate conceptual mastery and then give them the exact answer. The calculator is really quite amazing in its ability to determine appropriate degrees of allowable error and to prevent gaming of the system through any sort of trial and error. In fact, the logic built into the little machine would make one heck of a case study in a computer science class.

The calculator also allows for the estimating requirement to be turned off, but not with out a set of randomly flashing LEDs alerting instructors that students aren’t stepping through the full process in determining their answers. It isn’t often that a device will make me really say “Wow – this could be a game-changer.” The QAMA calculator, though, is precisely that. At around $20 a piece, these little devices are quite inexpensive and yet stand to change the way a couple generations of students have been using calculators. The ability to simply estimate is so critical in not just mathematics, but in all applications of math; the QAMA calculator is a no-brainer place to start in shifting the way our students learn math, logic, reasoning, and more.

C12 Interview Danny Boice Speek

C12 Interview: Danny Boice of Speek

C12 Interview Danny Boice Speek

In this C12 interview Christopher Dawson sat down with Danny Boice, co-founder of Speek. Danny Boice teamed up with John Bracken who founded Evite back in 90ies. Together they thought about industries that could be disrupted with VoIP technology and a viral subscription model. They came up with conference calling.

Speek gives users a unique link, for example Danny Boice has speek.com/danny. When Danny wants to setup a conference call he just gives participants this link instead of handing out a telephone number and pin code to every caller. The system works over VoIP.

C12 #9 BotW

C12 Episode 9 Blog of the Week: Web 2.0 Classroom

C12 #9 BotWChristopher Dawson’s blog of the week is Web 2.0 Classroom with a post about using VoiceThread in the classroom.

I think collaboration and reflection are 2 of the biggest skills that kids need but aren’t really getting enough of. Having the opportunity to work together in meaningful ways and to reflect on their work and the work of their peers is key to being a learner. There are lots of tools that you can use to help kids collaborate and reflect. Blogs are a great example. Podcasts are another. However, each can be daunting to set up and actually do.

That’s why I love Voicethread.
