I really think that blackboard is a very good learning tool that can help language teachers and teachers of other subjects create personalized and engaging learning experiences that can result in better learning outcomes. I actually read a little bit about blackboard and I found that it is not only one of the most popular learning management systems in the world, but also its brochure mentions that currently more than 700 teachers are using it for over 2000 courses, a dramatic progress from only six in 1999 (

The good thing about Blackboard is that it is equipped with some tools so that it can function as an authoring tool for the learning content, an administrative tool, and as a means of communication. The content authoring features in Blackboard can be used for pure online or blended learning. As an administrative tool, Blackboard is capable of recording all students’ access to the materials and it can help teachers - especially language teachers - see their students’ progress so that they can make further reflections.
As a communication tool, Blackboard provides emails (in one-to-one and public exchanges) and discussion boards. In addition, I read that Blackboard can also integrate other communication tools from other operators that can enable users to communicate using voice bulletin boards or voice emails.
