<p>It seems to vary by professor. Personally, I’ve banned both cell phones and laptops in my class. At the outset, and in fact before class starts, in my introductory email, I explain my policy and most importantly WHY I have that policy. i then revisit this issue on the first day of class.</p>
<p>I find if I give a strong enough educational justification, they accept it. I invest a lot in my class, my students really believe me that I have their best interests at heart, and they accept my rules. </p>
<p>That doesn’t stop the occasional phone going off or me seeing someone texting, but I handle those odd situations with humor and for the most part, it works. </p>
<p>To students, if you are in a class of 70 or less, be assured the professor SEES you. They notice when you are talking, writing notes and passing them, texting under the desk, or dozing off. It’s part of our job to notice and read the audience and frankly ,students have not a CLUE how visible they are. And keep in mind, just because they don’t say something doesn’t mean it’s not impacting them.</p>
