Step 1: Group work and present dubbing T: Now everybody, let’s put everything we have got together. Here are the snapshots from the video we watch at the beginning. Let’s use the sentences in the text to describe them. T: I think it’s time to try something special: put a sound track into the video – dubbing. T: Let’s work in groups. You may use all the information we have here (teacher pointing at the material just mentioned). It is even better if you put in your comments and questions. T: Here are the snapshots and time of the video. I hope they are helpful. T: Remember, the video is 2 minute 7 seconds. Prepare your notes for just 2 minute 7 seconds. ?Teacher gives the students a piece of paper with the snapshots of the video to help them organize their notes into a script for the video. ?Students work in groups and prepare a script for the video. They may use the material they just used and are encouraged to add creative ideas. ?Teacher chooses 2 groups to present their work with the video together.
