I learned touch typing in high school about 50 years ago! Best thing I learned in school. I have used the skill nearly every day of my life. There was a time when I could hit nearly 120 wpm on an electric typewriter. I could push an old teletype machine to its max of 100 wpm, and sometimes exceed that and lock it up!!

I hope you appreciate the great value of what you do even if few students ever thank you. I've always felt bad that I never thanked mine. But since when does a16 year old thank a teacher?

BTW, I have a business Ph.D. and taught at a university from which I'm now retired.

I wasn't typing that fast in high school. Probably 30-40 wpm. But it was a sufficient excuse to beg my parents to get me a typewriter. At the time it was an old Royal manual like the one I learned on. By the time I was working on my dissertation I had access to a Selectric machine at the beginning but portable PCs were appearing so I got an Osborne I - $1800.00 at the time. It came with a really nice word processor but you had to manually enter special codes for all the amenities like bold or underline. It was a little slower than the typewriter but later there was MS Word which I still use.

FWIW I will thank you on behalf of all high schoolers who took typing. My daughter did, as well.
