Another book in the same vein is The Trouble With Boys by Peg Tyre. This book is also an interesting read, and it pretty much corroborates Richard Whitmore's argument.
So, what are you waiting for? Go pick up these books and read, read, read! Don't forget to write a reflective summary for professional development credit. How will the data reported in these texts influence how you plan your classroom instruction? Will you differentiate your lessons to accommodate for how males learn best? Hmmm...that's some heavy thinking there. Happy Reading!
