At most elementary schools, it is recommended for students to set aside quiet time and read self-selected novels a minimum of 30 minutes a day. Some middle schools even "stop and drop" whatever they're doing for a 20-minute reading break in the middle of the school day.
But something happens in high school, and as a former English teacher, I consistently noticed teenagers' abhorrence for assigned reading; it's become a means to an end. They read to write a paper or pass a test, not for the pure joy of it.
Spark Notes, defined as a "resource you can turn to when you're confuzzled," has replaced assigned reading. The Spark Notes website goes on to explain, "Sometimes you don't understand your teacher, your textbooks make no sense, and you have to read sixteen chapters by tomorrow."
