Last week I did a calculation on the board in my physics class. The physics was simple (just two lines), but the algebra to solve the problem involved most of the board. Must to my dismay (horror? surprise?), instead of writing down the derivation, several of the students took out their camera phones and snapped pics of it. "If I copy it down, I might make a mistake," was the response to my, well, sarcastic questioning. The art of note-taking is fading, fading... gone.
About half of my physics students are architecture majors. If you aren't aware, architecture students get worked hard in their classes. I understand that, truly, but there's a level of work that you need to put into physics to understand it. Problem-solving is a skill learned through practice, not just by watching someone else perform calculations. I approached a few of my students about their (non-existant) homework scores, and they sheepishly admitted they needed to put in more work. But they also said, "At least when you were a physics major, you could just concentrate on the physics, without having all this other work to do." Yes, I remember, back in the day, when I was required to take only one class each semester so I could give my attention solely to learning physics.... Everybody's own major is the hardest, isn't it?
