Plain talk is good talk
If you're trying to persuade people to do something, or buy something, it seems
to me you should use their language, the language they use every day, and the
language in which they think. We try to write in the vernacular.
I wonder how many members of the public understand terms like pedagogy, differentiated instruction, and the like? And I wonder how many education professionals use this kind of jargon when talking to them?
I like big words as much as the next guy, but when you're trying to communicate with someone, you've got to speak their language. Just some food for thought...
