I especially like this idea for making a video clip vocabulary exchange. Each student makes a short 10-20 second clip presenting the pronunciation, spelling and definition of a word. They could use a tablet, smartphone, or camera with short video capability.
Personally, I would do this by assigning a category such as adverbs, adjectives, prepositions, action or linking verbs starting with a particular letter or nouns that name things in a particular category ~ the possibilities abound. Students can compile a video vocabulary file by sharing their video compositions with each other.
This would be a useful activity anytime, but very productive for early speakers of English who cannot yet express themselves well through written composition, but could complete this video task fairly easily. Even intermediate students would benefit from the activity by helping them create a visual memory for higher level vocabulary words.
I also found an activity that I will adapt and use for my phonology practicum. I will add intonation markings to indicate the final/rising pattern in YES/NO questions.My learner also needs to address R-controlled vowels so this Truth or Dare game with words that contain vowels followed by R will serve both purposes.
