Well, yes and no - facebook is a platform that has a bias toward anonymity which lowers inhibitions, so this teacher probably never would have flirted in person with students, but did online.  Also facebook has limited expression - and it is documented.  If this happened in "real time" - nothing likely would have come of it.  I"m not excusing the teacher, but we need to guard ourselves against tech

This quest seems mostly concerned with students finding information rather than students creating info.

This quest isn't too bad, however, the students are just out finding facts. At no point does the webquest expect students to synthesize info or speculate or use any higher order thinking.

This quest seems really unfocused, but at the same time doesn't actually get kids to think, just find trivial info about a baseball player

Out of this list, very few would promote the goals most teachers have for students.  Most of the tools assume kids are already highly motivated learners.

Pay close attention to the caution the lead researcher uses.  The headline says "tech improves learning", the researchers know better.  More likely, the teachers were more willing to try new teaching strategies because they were going to have to learn the technology anyway.
