I always had a problem with things being taught the long old way. im all for basic maths etc, its important to know the foundations. but when it comes to a lot of things, they are overtaught to the point industry and trade bosses laugh a lot of the time.
speaking for my own field, at horticultural college, we were taught irrigation scheduling. now the maths we were given had the teacher, who mind you had watered massive golf courses all his life very accurately, more confused than us.
I asked him if ever in his 30plus years of experience he had ever seen it done this way, anywhere in the world.
No.
Then why were we being taught things that werent relevant to the industries we were being trained to enter?
