If I could have afforded the schooling I once thought of being a teacher. I have been told I have the calm patience, but these days in the United States I would say no way. Schools in the USA are nothing more than rubber stamp and pass them along through the system. I have kin that thought it was a joke until she saw it personally that young people, 10 or 12 could not even tie their own shoes, tell time by an analog clock and other such. These days you almost can't fail a child that needs more school or more help because it throws off the metrics or whatever for the school and the parents would rather see their kids pass but be functionally illiterate or unable to do simple arithmetic I learned before third grade than admit they failed as parents in teaching simple skills they believe schools should take over and do as babysitters.
There is a profound difference between being a teacher and being an educator...
There is something wrong with the current modern way of doing education when almost every country have a share of the population which doesn't learn the basics about reading, writing and basic arithmetics by the time they are 18.
But then we compare the actual state of our education with the education system of 50 or 100 years ago, when many or most people didn't even have a complete formal education, or had an education directly aimed to make factory workers or housewives.
So how we know how good we have it today or how we can change?
In Brazil we have the celebrated educational theorist Paulo Freire, which is known worldwide for his opposition against "banking education"; ie: the idea that students should be only passive learners and reproductors of knowledge.
Without arguing if he was right or wrong; but how we want to implement a modern education system, where students are active learners and knowlegable adults if we force teachers to follow the same, uniform, stiff kind of curriculum in every class, on every school, ignoring every different type of student, in every state and city of our countries?
Very hard to know. Sometimes watching the classes, it really feels like why we are supposed to make young people wake up at 8 AM in the morning to learn stuff like literacy or how to write a text, while they really don't care and really won't need anything like that in their life.
But we don't want a population who is illiterate, or people who can't write a simple text. Most countries need their scientists, they need their basic technicians (though some countries can just import new ones).
Maybe we won't have any need of the classic high school classroom in the future. Maybe the issue is how our culture deals with knowledge and education. We also have ignorant parents who turn into voters, who don't care about education as a voting issue and, in consequence, about education in general.
Who knows.
