Schools this year have started an initiative called Bring your Own Device. But is this really necessary? Taking your device to school allows kids to get information immediately while being taught in class. Children will learn to use various apps & websites like cool math, edmodo, eeko kids which will develop their knowledge. Your child will learn how to use the internet responsibly. Further the teachers will monitor your child's activity on the net so parents can track and see what is being done.
On the other hand bring your own device can cause certain challenges. One, if the kids lose their device it’s not the schools’ responsibility – this brings in not just the cost factor but also students looking after their device. This may be difficult for younger grades.
Further, the schools must ensure that kids do not misuse the internet. Also he internet will also use up the devices giga bytes based on what the kids download – this could reduce capacity of the device..
I do not have enough information on this initiative to comment further, but I think it is not going to be easy for a teacher to monitor every student while they are using their devices. But educating students and teaching them responsibility maybe a good way to start.
