Check out 50 More Things New Teachers Need To Know at Gently Hew Stone. Number 13 advises:
Don’t try to “convert” your students to a love of reading, or any other aspect of your subject. They are almost certain to come into your class with deeply set prejudices about academic activities, prejudices that you’re not likely to impact. Yes, give them opportunities to experience the joy of your subject, and show them your enthusiasm for it (that’ll be valuable for those who do have open minds), but don’t be afraid to assign reading, writing, and any other kind of assignment as a chore. Your best shot for reaching kids with any kind of meaningful seriousness about most things will be to honestly tell them that whether or not they like it, it’s important and necessary. They’ll groan and whine, but at least you can dispense with the cheerleading and get down to some real content. Ultimately, that’ll reward everybody.
