Some courses are dependent on technology, while others are not. Be aware that instructors may have different rules about the use of cell phones and computers in their class. There’s nothing worse than an instructor looking up trying to make an important point about the subject at hand and seeing 20 students clicking away on their cell phones or computers, checking their emails, or sending off text messages. Stay engaged in the class, be alert, pay attention, or you might miss an important point. If the instructor allows you to use cell phones and computers during class, you still need to pay attention. Sending emails to friends during a lecture is not only inconsiderate to the instructor, but it shows a lack of respect to the subject, which are part of your academic goals.
