Embedplus is a nice tool that’s on The Best Tools For Cutting-Out & Saving Portions Of Online Videos (Or Annotating Them) list. They recently added a really neat dictionary feature called Learn how to pronounce words (and use them).
You type in a word, and it shows you multiple short clips from videos where the word is used. Jeez, so many dictionaries are next to useless for English Language Learners because they either just show the word in writing or only pronounce the word itself. Some might include a written sentence demonstrating it in context. But you can’t beat literally seeing and hearing it!
Of course, the videos are all from YouTube, which make it inaccessible for most schools. But students certainly use it at home.
I’m adding it to The Best Reference Websites For English Language Learners.
