Chapter 4, cont'd

"We cannot anticipate every hidden message our students might encounter online, so we have to make sure they understand how to examine all information in order to determine its purpose." (p. 56)

I think this skill is so crucial, and so hard to teach to elementary school children.  I tried to teach this to my class every single year.  Some students get it, but it's an abstract skill that just eludes so many of them.
