There are many answers to your question, and I hope that many enotes editors will offer answers that are quite different than mine.
One aspect of a balanced approach to literacy is that reading and writing complement each other. Specifically, when a class works on a particular genre of literature, they should have an opportunity to both read and write that same genre.
For example, I recently completed a unit on Social Issues. One of the end products was for students to write and present a speech on a social issue, such as bullying, drug abuse, teen pregnancy, racism, etc. During this unit, we both read and wrote speeches on social issues. Our most important text for reading (and listening) was Martin Luther King's "I Have a Dream" speech.
You cannot write in a particular genre if you have never read any exemplary texts from that genre. Conversely, you will have better comprehension of a genre as a reader if you have had the experience of trying to write it.
