Collaborative Groups Strategies

Hi All!!!
It's been a while since I last posted something... Sorry for the detail. I promise I'll be upgrading my page weekly!!!

One of the problems ESL teachers have when it comes to collaborative learning is that a few (even only one student) is the one who develops the activity, and the rest just lean on that person. Here, I'm proposing two activities I learned at a TESOL Conevention in San Juan, Puerto Rico:
1. Prepare dialogues for two students. Student A will be reading his/her as student B listens and completes the blanks. Then, student B reads his/hers as student A fills in the blanks.
This activity enhances the listening skill. I use it especially for the ed endings and all verb tenses!

2. Prepare pieces of papers with vocabulary, verb tenses, or idioms. Then, divide the class in small gropus. A piece of paper will be given to each group. Student 1 will write his/ her sentence. When the teacher indicates, the sheet of paper will be passed to Student 2 who has to read Student's 1 sentence and then adds his/hers with the word/phrase given. It continues until all students write their sentences. A couple of minutes will be given so that students correct the paracgraph in terms of spelling, verb tenses, etc. At the end the teacher reads all the compositions and selects the winning group!

My students love it!
Enjoy, and let me know...
