Jim Trelease's Read-Aloud Handbook had a very big impact at Chez Gauthier. I went to hear Trelease speak at our local elementary school when my oldest child was still a toddler. I brought his book home with me. His contention that boys model their behavior on their fathers and need to see their fathers (as well as other men) read, meant that the Gauthier boys had both parents reading to them (on alternating days) for years. They continued to read, themselves, into adolsecence, a point where conventional wisdom tells us that many males stop reading. And, surprise, today they tend to share their father's books and magazines rather than their mother's.
This makes me wonder what would have become of them if they hadn't had a reading father to model themselves upon or, even, a reading father who didn't know he needed to provide a model for his children. (This is what I call proactive parenting versus reactive parenting, by the way. But this isn't a parenting blog, so I won't say anymore about that.)
Just a few months ago I gave a young teaching family member a copy of The Read-Aloud Handbook for Christmas because I just can't let it go.
The book really has significance for me, so I'm happy to direct you to Jen Robinson's "reaction" to it.
