This text's unique constructivist approach guides students in learning by doing. Geared to teachers of preschool through sixth grade students, it represents the cutting edge of elementary science teaching with up-to-date investigations into contemporary topics.
This text is full of helpful strategies, but is vague in places of importance. Where there should have been talk of pedagogy I found a light touch on instruction and more about content. This directly contradicts what the text says about how much science knowledge teachers have to have (which is said to be "not much"). The author didn't seem to be able to make up his mind when it came to content vs. instruction and the melding of the two.
As scattered as this text is, it does provide a lot of great strategies for teaching, but that can all be found on the internet just as easily without having to pay the hefty price.
