Here is an activity my English students did in order to practice properly writing quotations.
Much of it was borrowed from a lesson plan I found on the National Writing Project website. On their site you will find a variety of situations that would involve conversations.
I instructed the students to work in pairs. Each duo selected a scenario, then composed a dialogue. At first, the students tried using a website called, “Collabedit,” which is supposed to allow multiple authors to collaborate in real-time on a single document. Unfortunately, we found this website to be too buggy; the students encountered many glitches and error messages. So, we had to settle on using good old Microsoft Word.
Writing collaboratively was fun and the students were very motivated to write.
