The AAC text book uses Electron Flow, which is explain early in the book in this chapter.

In many cases it doesn't matter which standard is used, but there are some exceptions. Tubes (aka Valves) for example depend on boiling off the electrons with its heater to make it work. Only electron flow explains this behavior.
There are other examples, but the point is rather that go back and forth between a flawed standard that was created by Benjamin Franklin (that is still taught in schools today) or the modern standard that fits all the known facts this text book will stay consistent.
Many people have not been introduced to these concepts, and again, in many cases it doesn't matter while learning. But this text book uses electron flow theory, and none of the chapters or sections in the book will be corrected to reflect conventional flow theory.
