Thanks for all the information about blogging and how to use it to engage students.
Note: Your comments about "head" and "heart" (referring to younger students and older adults) needs to be clearer.
Do you mean that younger people are not able to engage in the same quality/level of reasoning adults engage in? This is a contestable claim.
What is the evidence for this?
Piaget was wrong. Children can also philosophize well if adults allow them to.
Side Note: Look also at David Hume's description that people (young and old) are a "bundle of sense impressions."
There are also mutiple adults who reason through their emotions (if that's what you mean) as well as children who, if allowed, can think more like Socrates )more logical) and less like their Peter Pan parents.
