Creative Video From Ned Hostetler, an eighth grade history teacher at Orrville Junior High School in Orrville, Ohio: ì(I picked this up at a technology in the classroom seminar by Hall Davidson.) I use the closed captioning feature when I show videos to my classes. By running closed captioning, students see all the words being spoken with the correct spelling. Sometimes students donít pick up all the words just by sound, so closed captioning allows them to pick up on what they might have missed.
