I have written a (so far unpublished) book called 'Understanding Complex Information Technology Solutions: A Case Study on Moodle'. My target readership are people who are familiar with using today's technologies (web-based systems, mobile devices), but do not know how these technologies work (this could be first year information technology students or teachers/administrators working with Moodle, or anyone interested).
I take Moodle as example to talk through the technical details (starting from what is a web-based system down to database design, PHP coding and HTTP protocols). I also cover people and institutional aspects. The idea is to use a concrete system (with all its complexities) to make complex technologies and their interactions accessible. The book does not explain how to use Moodle or how to teach using Moodle, but it explores Moodle from a technology perspective.
At this stage I am planing to publish on Kindle Direct Publishing - before I do so, I would very much appreciate feedback from members of the Moodle community. I have attached a TOC to give you a better idea about the book content. I am happy to provide more details in this forum. Should you be willing to review the book (or sections), please give me your email address to I can send the manuscript to you (email@example.com).
