If the student in question uses the word not because it was in his usual vocabulary but because it appeared in the article about Magellan, the teacher has a valid point.
Not really. I'm sure "circumnavigate" wasn't in my usual vocabulary but its meaning is simple enough to determine from context. I don't think its reasonable to penalize someone for using a word they would pretty much have to pick up when learning about a topic.
The other thing about this educational strategy is that, all other effects aside, it discourages students from using more sophisticated vocabulary. If you try to use a complicated word and get it wrong, you will be punished. If you get it right but the teacher doesn't believe you did so deliberately, you will also be punished. That's a terrible lesson to teach children (or anyone else).
New chapter!
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 102.
There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
