The More
Things Change:
"Students today can't prepare bark to calculate their problems. They depend upon their slates,
which are more expensive. What will they do when their slate is dropped and it breaks? They will be
unable to write!"
Teachers Conference, 1703
"Students today depend upon paper too much. They don't know how to write on slate without chalk dust all over themselves. They can't clean a slate properly. What will they
do when they run out of paper?
Principal's Association, 1815
"Students today depend too much on ink. They don't know how to use a pen knife to sharpen a pencil. Pen and ink will never
replace the pencil."National Association
of Teachers, 1907
"Students today depend too much upon store bought ink. They don't know how to make
their own. When they run out of ink, they will be unable to write words or ciphers until
their next trip to the settlement. This is a sad commentary on modern education.”
The Rural American Teacher, 1929
"Students today depend upon these expensive fountain pens. They can no
longer write with a straight pen and nib (not to mention sharpening their own quills). We
parents must not allow them to wallow in such luxury to the detriment of learning how to cope in the real business world, which is
not so extravagant.”
PTA Grazette, 1941
"Ball point pens will be the ruin of education in our country. Students use
these devices and throw them away. The American virtues of thrift and frugality are being discarded. Business and banks will
never allow such expensive luxuries.”
Federal Teacher, 1950
"Students today depend too much on
hand held calculators."
Anonymous, 1985
