But IS she talking about that? She seems to be referring to her son as a teacher of 14 yr olds so doesn't make sense.
Also schools absolutely do have a responsibility to help kids with behaviour and socialisation. It's one of the reason schools exist rather than home tutors, schools came around as we know them as part of industrialization and getting people ready for the workplace. They are institutions of care and learning in more than an academic way. Or why would they have a school nurse for example?
Perhaps what op means is TEACHERS are not primarily childcare and that I'd agree with but the overall institution of 'school' is more than the teacher and more than just education and is part of a larger social construct. So both my children have emergency medications kept at school, without a school nurse and specific teaching assistants these couldn't be kept in school and my children couldn't safely attend but children with health conditions are also entitled to an education.
Similarly children with SEN and even just children with shit parents are entitled to an education, it's an actual human right of a child, therefore the provision of the surrounding care is also the responsibility of the education system in order for it to provide it's purpose.
Trying to say school should be purely academic would exclude so much and so many from school.
There is care as part of the school system, it provides childcare as part of its social structure
People who want to whine that parents should be, I'm not even sure what, providing round the clock supervision even within schools? Attending school with their children? Standing outside with emergency meds thatay need administered in the event of an asthma attack, anaphylactic shock or seizure?
