Just as a background on me: I have a graduate degree in Geology with a focus on ancient environments and climate. I was viewing this course in advance of my 12 year old daughter to make sure the content would be suitable for her. For me, the content was simply review.

This course was overall very disappointing. It should have been titled "A Broad Survey of Topics in Ecology." The topics were not covered in any depth. In fact, if you've been watching Nova on PBS or anything on the Discovery or National Geographic Channels, this material will be a review for you. I would have preferred to have fewer topics addressed, but more in-depth material presented. Honestly, my 12 year old has covered much of this material already in her schooling...and since I was viewing this course to potentially give to her, I decided that it mostly would be a waste of her time to watch it.

The other big disappointments were the blatant mistakes the instructor made during the lectures. Honestly, there is no excuse for these. Someone knowledgeable in the sciences should have reviewed the content of these DVDs before this course was published. I'd be happy to do this for Great Courses in the future, as would a host of other scientists or science writers - anyone with a moderate amount of education in the natural sciences could have caught these mistakes. Here are a few:

-The instructor talks about tsunamis being "storms" and are made more intense with global warming. Not true on both counts. A tsunami is NOT a storm - it is a wave of water caused by seismic or volcanic activity near or below a large body of water (usually the ocean, but it's conceivable to have a tsunami-like wave on a very large lake).
