I think it’s simple: the reign of the essay is over. Educators must find a new way to judge a student’s understanding.
Presentations, artwork, in class writing, media, discussions and debates, skits, even good old fashioned quizzes all still work fine for getting students to demonstrate understanding.
As the son of two teachers I remember my parents spending hours in the evenings grading essays. While writing is a critical skill, and essays contain a good bit of information, I’m not sure education wasn’t overindexing on them already. They’re easy to assign and grade, but there’s so much toil on both ends unrelated to the core subject matter.
