“In 2018, teachers and students used social media to let the world in. Viral posts shared moments of joy, laughter and even anger. Educators responded to the news — and sometimes they made news.

We’ve been gathering up the most notable of those school-related viral moments of the year — our roundup is below.

(A quick caution: While we’ve done what we could to check them out, these stories are presented with the caveat that it’s not always possible to know the full background behind every post shared on social media. The recent New York Times expose of a school in Louisiana is an example. That school got famous because of feel-good videos showing students getting into colleges like Harvard; the reality was far darker.)”
