Angel A. Juan (Open University of Catalonia, Spain), Maria A. Huertas (Open University of Catalonia, Spain), Sven Trenholm (Loughborough University, UK) and Cristina Steegmann (Open University of Catalonia, Spain)

It seems that they sell each section inside of the book separately, with $37.50 per piece. Good idea. Because I AM more interested in some specific sections than others, such as:

Online Communities of Practice as Vehicles for Teacher Professional Development

Best Practices for Hybrid Mathematics Courses
