The way I would use the Blog as a Teaching Tool

1. Use a Blog as a teaching tool posting a specific topic and asking to the students to feedback about it creating a discussion environment, then students could practice and improve their English skills at the same time I Evaluate their levels and knowledge.

2. Use a blog as a teaching tool asking to the students to créate their own blog like if that were their notebooks then they could develop their homeworks and  do group activities practicing English and topics with their mates.
