“Explore ten ‘big ideas’ that encapsulate the technological and social trends that have pushed geographic information systems (GIS) onto the Internet in a significant way. See how to apply these ideas to your own world. Open your eyes to what is now possible with Web GIS, and put the technology and deep data resources in your hands via the Quickstarts and Learn ArcGIS lessons that are included in each chapter.”
I haven’t fully previewed this online textbook yet but I am VERY optimistic about this one from the ESRI library. You can also download the textbook as a PDF here. There are several other online textbooks that would interest geography teachers
