a) the graphical capabilities are a lot more efficient than point
plotting, and everyone gets the same answer, which makes teaching more
efficient
b) when the issue is NOT calculation, but concept, the student spends
the time on the concept, rather than being distracted by the
calculation (which is slower, and of course could be in error, thereby
slowing down the teaching).
Too much to cover, and too little time, with the added problem that in
many cl*****, assigning homework is a waste unless you reserve time to
get the kids well started in class. Half of them won't do the
homework at home, being too involved in s****ts, family, the opposite
***, job (The US is the developed country which has by far the highest
percentage of high school students working more than 10, 20 or even 30
hours a week. Gotta "make money fast!!!" when you are a teen.)
