I remember back when I was going to West Valley Community College in the 1980s that a few professors at other schools (thankfully not at West Valley) had banned those “newfangled Macintoshes.” They thought that typing on a typewriter made for better thinking processes (seriously, that’s what a few of them thought). Probably so, but I knew then that these folks were stuck in the mud and that we should have, instead, banned the professors from ever setting foot in a classroom again.
I have the same feeling about professors who ban Google and Wikipedia.
If I were a professor and I wanted my students to go deeper than “first level Google searches” I’d just grade tougher. Really, is it any more difficult than that? Geesh.
