In line with The Open University's mission to be "open," the first textbook for their compulsory Computing and IT module is very open in its approach. It offers an overview of several topics in computing—such as the history of computing, binary logic, HTML, and design principles—without delving into any of them in significant depth. Since The Open University textbooks are available for purchase by the general public, this might be a suitable resource for someone with less than GCSE-level computing knowledge looking for a primer. However, I’d argue that someone in this position might be better off identifying a specific topic, like HTML, and buying a focused introductory book on that subject.
That said, while I don’t consider myself the target audience for this book, having no formal computing training, it did help consolidate some of the knowledge I already possess and provided additional context. I also found it well-written and didn’t feel bored while reading it. However, if I were paying over £1,500 (at current rates) for this module out of pocket, I’d feel short-changed. I believe this module should be optional for those of us with more than basic computing knowledge, so we could instead focus on something more valuable (for example, an introductory stats module would have been far more beneficial to me). But I’m getting into module-level commentary here, not just the book itself. The book is fine for what it is, but I’m left wondering who the target audience really is.
