Mr. Jensen has saved me and other teachers the time of gathering together the latest information about the brain, learning and so much more! He has made all this scholarly research accessible and fun to read. I wish the deadwood at my school would at least read this book but I hope they would also use the great ideas in it, too, for the students' sake!
Output:
Positive
