Here are a few recommended questions to start with as students are searching the internet:
Who made this?
Who is the target audience?
Who paid for this? Or, who gets paid if you click on this?
Who might benefit or be harmed by this message?
What is left out of this message that might be important?
Is this credible (and what makes you think that)?
(Thanks to Project Look Sharp for these questions.)
Helping our students critically read and reflect on their own thinking is a tall order but a worthwhile project.
