When applying for graduate assistantships or part-time teaching for grad school scholarships, is university teaching necessarily better than highschool teaching experience? if so, by how much?
Possibly relevant details:
I am graduating soon with a master's degree from a third world university.
My plan is to get a PhD but am considering getting teaching experience to boost my chance's of getting in.
I am considering teaching at my university (or another university in my country) for a year or so.
However, I have something like a dual citizenship in a first world country in the sense that I permitted to work there in addition to an established residence (my mom and sister live there while my dad and brother live with me).
Said FWC is where I would like to get my PhD.
My parents suggested I teach at my sister's highschool (or some highschool in said FWC since I will unlikely get into one of the universities there).
I am fine with either in terms of job requirements (e.g. highschool has more requirements and students tend to snooze off more), but the pay is alarmingly different by a factor of 5.
Another difference is that if I teach in my university long enough, I might be able to teach or assist in teaching advanced stuff like probability, linear algebra, calculus III or financial maths. There's also a tutorial center nearby and there are occasional students who need tutorials in probability, statistics and linear algebra.
