Here’s a nice piece of software…

It’s TI week here at OMT.

TI SmartView is a lovely piece of software… (see embedded video):

If I am teaching Advanced Mathematical Button Pushing, I am going to need this software. But honestly, that’s about it. It costs more than the calculator it is emulating and requires a fully functioning computer to run on.

It cripples the teacher with the same crummy graphics (94 pixels, horizontally) that students have in their hands. And it records every single button push. All of them, down to the last 5 up arrows.

You know how annoying it is when you get directions from Google Maps and the first five turns tell you how to get out of your own neighborhood? Same deal here. There is truly no intelligence built in.

Oh, and licensing? Crazy restrictive. My institution pays per license, and it’s not the “running on x computers at a time” sort of license. It’s the “installed on x computers at a time” sort of license.

Does anybody at TI check the math?

I get that the images below are not real classrooms. These are combinations of staged and stock photos. I get that. But seriously, a waterfall with a straight-line cross-section? And just what answer do we expect to the “shade 1/6 of the hexagon” task? Is the resolution on that screen good enough to detect the difference between 1/4 and 1/6? And how will the teacher tell that difference at a glance? Do YOU know which of those responses is correct?

Note the right triangle on the NSpire screen. And the "Real-world" connection: "Diagonal distance of a waterfall".

We're filling from the bottom up. If height of hexagon is 1 unit, what fraction SHOULD we fill to? And how exactly do these images help me assess whether students can find it?
