While dated it still provides an excellent overview and some history of the topic. The appendix provides an outline summary of the important points that should be used as a checklist for professors and administrators looking to commence hybrid learning.
Jason covers everything that is going on in hybrid learning today. Particularly useful was the chapter "Hybrids in Action" and the inclusion of the international perspective. This book makes you really think in depth about the challenges that teaching hybrid classes presents... it's not just splitting the curriculum. Highly recommended.
