**Update: The digital action plan for education was released on May 30. You can read it here (in French). My understanding is that an English translation should be available in October. Keep posted for my (unofficial) synopsis of it in English in the near future.***
There is no one easy answer to that question. I’d say it depends, as does everything we choose for our classrooms, on our goals.
Right away though, I’d say DON’T buy a whack of devices to put in one room. Remember computer labs? **insert crickets here** I know that some schools and centres still have labs and when asked my opinion, I suggest to take them down and divvy up the machines amongst your classrooms.
I would also warn away from putting all of your devices on a cart that needs to be reserved ahead of time.
Many of our schools and centres are moving towards flexible learning environments based on the principles of Universal Design for Learning – this requires flexible access to technology for learning, too.
The best use of technology is when it is available when you need it. If you redistribute the 20-30 computers that are in your computer lab, you can have a few per classroom. And if you have the luxury of purchasing some new devices (and we DO have that luxury this year in Quebec with our plan d’action numérique!) then you can add to those numbers. If you are contemplating a cart for devices (tablets, chromebooks, laptops…), I’d suggest to make sure that each classroom has some devices first and to use a cart for extra devices, when a group does need to all have a device at the same time.
What if each of your classrooms already has a number of devices? Then you may be interested in exploring some of the other items you can purchase to add to your curricula through robotics or open creative spaces. In fact, the only time I would suggest putting a lot of material into one room would be if your school or centre is in the process of developing a culture of shared collaboration and creativity through an open creative space (also known as a maker space). So that room would not be like a computer lab to go sit and do research or type a final copy of something but a room where students and teachers can learn together as they test out new ideas and create new solutions.
