If a teacher is paid to teach typing, it is unreasonable to expect him to change the curriculum to word processing. His contract will be to "teach typing on a typewriter", NOT to "buy computers and programs needed to teach computerized word processing.
Perhaps the person or institution who hires that teacher is responsible. Blaming the teacher is simply moronic.
When someone needs a specific task done, it must define the tasks required and then teach them, as NASA did. When space sciences was formed, no one had attempted to put a man in orbit. The Soviets had to decide how to get a Sputnik in orbit, then they had to figure out how to put a man in orbit and bring him back alive. NASA confronted and overcame the same problems.
I cannot recall any sane people who blamed their HS Physics teacher for not reaching the Moon.
