Looking for a video to help teacher relate to ELL students in classroom.?

I once saw a video in a grad school class for educators about ELL students, and can't seem to find it or any mention of it no matter how many ways I search! The presenter in the video showed a list of common English words, maybe 20 of them. The participants were asked if they knew the meaning of the words, they agreed that they did, and then the words were used in a paragraph that made NO sense, because it was a specialized business document... so even though the audience knew the words, they could not comprehend their meaning in the given context. Brilliant concept, would like to use it for a presentation I have to do for my coworkers about ELL education.
