It is very simple: education has become a commodity to be traded, sold and marketed by qualification.
And still it has lost all quality. To address a few points, not in particular order.
"The average cost of a new textbooks is $68, according to the National Association of College Stores, and many titles easily top the $200 mark."
Is This the Solution to Crazy High Textbook Prices?
$68 x 5 subjects needing books x 15 students per class = $5100 just for one small group for one year.
Only the teachers should have full textbooks, to teach from. Students should have workbooks, unless they do all their work on computers and smart phones. Either cuts costs by a large percentage.
Training, worth the cost, but some people just are not teacher material. They need to be found and persuaded to follow another career path.
New buildings, not necessary. Safe buildings, yes. Most of the main buildings in the schools I attended were over 50 years old, and that was several decades ago. Equipment, especially, needs to be in good condition, but not new. The atmosphere is made by those eager to improve themselves, not by the surroundings. Note where Rocky always chose to train. Where he could get down to basics.
Social order. One of the enemies of education. What causes the most problems, as far as behavior in classrooms? Students showing off for each other. Begin by isolating any such influences. Send them to another class, a different grade or another school, and if all else fails, expel them.
Parents should not only be allowed, but encouraged to spend time in their children's classes, or even other classes taught by their children's teachers. It would be nice to see a parent or three in classrooms at least a few times a week.
The biggest thing is get federal guidelines out of schools. Local teachers and parents should decide the curriculum, not DC.
