I have an advertisement group project for 7th graders–they decide the product to be promoted, create prodcut name, slogan, ad plot, and then filming and editing using iMovie. Each group member is assigned a role–typing the script, prepare a word bank, and English subtitles. A rubrics is given. The grading includes written and oral parts, containing both individual and group grades. The one thing I wish they could do is using target language in their discussion. Any good suggestions?
