It's a classic question: what platform do we go with? Historically, this meant using a Mac or Windows machine, but in the mobile space this has become increasingly more complex. Today, there are Android, Chrome, Linux, iOS, and a variety of Windows 8 and RT devices. But, will investing in any one of these platforms be a sound investment five years from now?
That's a question addressed in a Mind/Shift article by Shawn Mccusker. He argues that student learning needs should dictate what platforms a school or institution chooses to adopt. Schools in particular need to be willing to make changes in the technology they use as their needs change.
This seasonal view of devices (rather than “device as school identity”) is essential to helping schools move forward, meet their current students’ needs, and keep the curriculum relevant and timely for the future. A focus on pedagogy and key technology skills will transfer from one device to another, making the shift easier; a focus on being a device expert, or mastering device specific mechanics, will not. Students will graduate into a world that will demand technological fluency, the ability to move and process information across various platforms and devices.
This is an important point, since technology changes so fast schools can't possibly latch onto one platform. Also, there isn't one universal tool for all learning outcomes. A school might purchase Windows computer and Macs if they are required for different purposes, while other students might be better off with iPads and/or Android tablets.
The approach that schools should teach "general" technology skills on a variety of platforms is not unlike what universities have been offering for a long time. Go to a university bookstore and you will likely find offerings from every platform. This diversification provides educators and students with considerably more choice and flexibility.
