Some pet phrases actually mean the exact opposite of what their words supposedly say. Take “urban renewal.” Those old enough to remember the 1960s know that this phrase was a synonym for slum clearance, or, in James Baldwin’s telling phrase, “Negro removal.”
The term “education innovation” is similar. Not simply an empty signifier, with a vague, uncertain meaning, the phrase usually refers to ways to make education faster and cheaper, more flexible, efficient and cost-effective.
