And it gives me the rage when teachers get their classes to do research/presentations on their phones in class. What about the 3 kids in class without a smart phone?
Students do presentations in groups. They work together to combine research from different places e.g. textbooks, additional material, photocopies, websites and so on. They don't all sit silently individually staring into their phone for 60 minutes. They share and collaborate with their friends/groups. Give me some credit that I know how to do my job please.
How did teachers manage to teach 10 years ago when no kid had a smart phone.
By not using them. In the same way that teachers have also taught in the past without using:
Whiteboards
Blackboards
Textbooks
Cassette tapes
CD players
IWBs
Computers
Pens
Paper
Rulers
Calculators
Desks
Humans have been teaching and learning since before we were sentient. However that doesn't mean that choosing not to use an available tool today because "We didn't have it when we were kids" is a good idea. Smartphones give children access to the sum total of human knowledge, at their fingertips, in real time. I think it's criminal to tell them that their phone has no practical use beyond the social.
A good teacher uses every available educational tool in the right way rather than rejecting something out of hand because of their own personal feelings about "What's wrong with kids these days".
With regards to trainers, I grew up in the 90s and wanted nothing more than a pair with those flashing red LEDs in the heel. However when I wanted to chat to my friends I was still able to use the landline phone, or go over to their houses, even though I didn't have flashing shoes. I got made fun of for buying all of my clothes in charity shops, but I wasn't excluded from communication avenues within the group, which is what you do by voluntarily banning your child from having a phone with app capabilities.
