My brother was a certified welder. When he retired he answered and ad for Daytona State College as a welding instructor. He became involved in helping to build their welding program. He got pomoted and became a leading teacher. But after ten years he is giving it up because out of every class of 25 only about 4 actually progress to become certified welders. The problem? The kids lack basic math skills. When I say basic, I mean that. Many have no undstanding of fractions or even simple addition or subtraction. He brought it up and was told to just move them along. He is giving it up.
In our world it is ok to be a jack of all trades with a wide understanding of many things. But you need to be the master of one so you can fall back on it when you are useful to society. Remember in school when you had to do all that math in your head? 2x2=4, 3x3=9, 4x4=16? That is not being done today in too many schools. It is racist aparently.
Mike Rowe has been alerting us to this for a long time. Education has got to get back to basics.
