The teacher was a quite old man who was set on his ways. We would have to draw 3D pieces by hand, using our squares, bevels and compasses, and lining everything with an ink pencil afterwards, and he gave us a lot of homework to do, which he examined for imperfections.
I was incredibly bad a it. I would start a drawing, only to discover halfway through it that it didn't fit the sheet of paper I had and I had to change the perspective. My perpendiculars were never perfectly aligned. I would smear blots of ink with my tools and hands.
It was excruciating.
This is the point where I would usually say that I learned to enjoy the repetition and eventually came to appreciate it and be good at it. But that's not what happened.
Instead I started doing my homework using the computer, printing, and then tracing the points by hand. This resulted on cleaner-looking homework and took less time to do. What's surprising perhaps is that it enabled me to appreciate design more, now that I was no longer limited by the drawing technique, which was, I believe, my teacher's real interest (he was a painter outside of school. A very nice person, I didn't enjoy lying to him like that).
You might think that this would prevent me from performing well on exams, where a clean enough drawing (done by hand) was expected. The thing is: I could muster the effort to do a one-off drawing that was clean and precise, from time to time. Just not after every lesson. I actually got the maximum qualification on my province's technical drawing examination.
This is all to say: I agree with the Author. Once the tools are out there, trying to limit them is pointless. You must adapt your curriculum to the environment your pupils are in. If you don't, they will.
