So far so good. I love this kind of stuff and have since elementary school (Not kidding). At any rate, thus far I find the material accessible and interesting. Definitely not light reading, but a good review for those who’ve had some introduction to the topic. Also good for educational researchers wanting to better understand (and design research to test/improve) instructional strategies. Lastly it’s a good foundational text exploring principles that learning designers need in order to be most effective. Still early on in the book, so we’ll see if my thoughts change later.
