Hey, Lisa - How did you like "Catcher in the Rye"? I remember it as my #1 pick at the school book fair (circa 1968) because it was so controversial. To this day, I can't understand why it is so highly regarded by so many. Like you, I came from a fairly religious household, but if my Mom caught me with a "bad" book (Valley of the Dolls comes to mind), her reaction was, "Well, if you want to waste your time with that junk, that's up to you." (She bought me Silas Marner which I put down after the first chapter.)
I am a former reporter, so I tend to favor the First Amendment. However, in the classroom, the teacher has to be a role model for what is appropriate and acceptable language and behavior.
The #1 genre for parents to challenge is "realistic fiction," mostly novels published after 1960 when teen issues started to be portrayed realistically. (Some parents go after the Harry Potter series for "witchcraft," but the books got so many kids reading that few really care if the books are available in the school library.) The most common complaints involve obscene language and adult (usually sexual) situations. Generally, parents think the content just isn't appropriate for the grade level.
The research is very clear - tell kids that adults don't want them to read a book, and they will want to read it.
As a former HS English teacher, I was very careful in selecting books. There are three levels of book availability that have to be considered: the ones available in the library for any of the students to check out, the ones available in the individual classrooms for the students to read during free time or check out from the teacher, and the ones that are actively taught as part of the curriculum. The teacher is the one who sets the example for the last two. Some of my colleagues liked to teach "edgy" books that the kids loved. However, I think if a teacher selects a particular book, he or she is sending a distinct message about the quality and value of the reading material. Books chosen for unit study are generally approved by the curriculum specialist, reading specialist, or (more commonly) a committee of teachers and administrators, because the books have to match the curriculum and state content standards. So, there's usually a good argument already for having a "challenged" book used in a classroom.
The teacher has to choose wisely - a book that has received an award or two is a definite plus (Pulitzer, Newbery, etc.). However, there are some that have received awards from various children's literature guilds that I would never use in a classroom for whole-group study. However, those books should still be available to students to read outside of class if they wish.
I was lucky in that I only had one complaint from a parent - the child was actually an 8th grade student in a highly accelerated honors class. (The course was taught at a local college.) The offending passage was a paragraph in "Power of One." The parent called my supervisor, who (bless her) read the entire book. She called the parent back and said, "This is not only one of the finest books I've ever read, it is THE best book I have ever read."
The same rules go for videos - most schools (my former one included) bar R-rated videos anyway. There are few videos I think worthy of showing in their entirety (October Sky is on my short list). However, I once did a unit on "heroes" and wanted to show a clip from Erin Brockovich. The movie is loaded with profanity - I showed a short segment of her picking up dead frogs with the volume turned down. I don't know if a parent would be upset if a student went home and said I had shown a video with "the f- word," but I never took that chance. Again, it's setting an example - it's not appropriate language for a classroom, and a teacher who permits profanity in the classroom deserves to get stung.
As a parent, I was very liberal. I frequently took my three kids to bookstores with the instructions that they could buy any books they wanted to. (Fortunately, they usually chose wisely, but I do have a rather annoying collection of "Goosebump" books.)
However, I don't think any parent has the right to ask a school library (or public library) to remove a book from the shelves. Some "controversial" but educational material dealing with sex, drugs, or politics are important for research, classwork, and just being informed. If the book is in the school library, then we can assume that a reponsible educator (e.g., a librarian) put it there for students to use.
This is a lot more than I expected to write this evening - I just logged on to see what others wrote then planned just a short response to Lisa's posting since we had "Catcher" in common . . .
