A conversation with a Maths teacher about Graphics Calculators triggered this post regarding Interface Design. There are quite a number of brands of this device on the market. The school I am currently working purchases class sets of these devices, however some students do want their own where the interface, and the hardware structure is very different. The school also needs to purchase new class sets. The existing graphic calculator that all the teaching staff are familiar with is no longer available, a new updated model is available with an interface that incorporates a touch screen and icons. There are also Graphic Calculator Apps available too that some students are wanting to bring into the classroom that can be used on computers and iPhones or iPods. The teacher's job in the Maths class will, I guess, include navigating all these different interfaces in the classroom when teaching and learning with graphic calculators.
This link highlights the differences re graphic calculators.
