After a brief introduction about the history of technology, this book goes on to discuss three women in particular that have impacted or are impacting technology as we know it. Grace Hopper worked for the Navy in the early days of computers, Shaundra Bryant Daily currently teaches computer programming to students, and Jean Yang is getting her doctorate's degree and planning to be a professor in computer science. This book is interesting and could be appealing to upper elementary students who are interested in technology or computing. I gave it a three star rating because I had trouble with the formatting on the pages. There are visual cues to let you know what chapter you are in and call-outs with additional information, but overall I felt that everything was given equal weight, resulting in a clutter that made it hard for my eyes to rest in any one place. There is minimal white space and it's written almost like a non-fiction chapter book. The call-outs and additional information areas competed for attention with the primary text, without any clear hierarchy. ( )
