<p>I’ve never seen anyone doing this in section. Lecture sure and in fact, I’ve seen profs try to ban laptops and totally fail cause their lectures are so boring plus the anonymity. GSIs in section though have dictatorial powers and you just know to not get on facebook and turn the phones off. Since it’s typically 50 mins once a week, no one has an issue going along with that. You always want to be paying attention when it’s 20-25% of your grade in that short time frame, plus a good section is engaging anyway.</p>
