Merriam-Webster defines jargon as "the technical terminology or characteristic idiom of a special activity, group, profession, or field of study."
For journalists, covering education means fending off lots of jargon. Going to a conference, like the American Educational Research Association annual meeting this week, or reading a research or policy paper, requires wading through waist-deep abstract terms and buzzwords. Many have lost their meaning through overuse, becoming cliches or euphemisms. Others smuggle a whole lot of questionable assumptions in a seemingly innocuous package.
