The New York Times periodically has made important speeches by President Obama extraordinarily accessible to English Language Learners, and they did it again today with his speech at Cairo University.
They show a video of the speech (usually not blocked by school content filters). On the right they show the transcript. As she speaks, the transcript scrolls down while the portion being spoken is highlighted. Plus, the whole video and transcript is “searchable.”
It also shows short snippets of commentary on the speech.
They don’t make words “clickable” for people to find definitions of words they don’t understand, but I guess you can’t have everything!
