How would I use blogs, wikis and delicious with my EFL students?

     I think that we should use technology in our classes with EFL students for example; Blogging is a great way to allow your EFL students to be  a “real” audience and connect with other learners using blogger posts to improve students  skills such as  writing  grammar, reading and other skills . Teacher asks the students to write a paragraph as about themselves  or description of an experiences in their life  to measure their ability in writing , and the other students who are members  group  comment and correct the mistakes of their friends' posts, or asks them to put photo in their blogger and asks them to describe it or add a comment about it to  measure their comprehensive by using a suitable words  and writing .

   By using delicious also, teacher can give the students hyper links to go over and also to share with other some links that useful for their course . Such as a web site offers  activities or worksheet that help students to improve their vocabulary such as  giving them multiple choices with sentences to choose the correct word and falling the blanks with suitable words , or links for reading text with general questions to improve their comprehension and reading skills . and asks them to bookmark an articles websites which can help them in their course and make them  more interesting.  

     By using wiki teacher and students  can create a data pace for the group works such as projects and creating lessons such as vocabulary and grammar activities and PowerPoint which can support their understanding . Students can set up their own wiki for summaries or notes. Teachers can set up a wiki for lesson notes or reading notes. Each student can be assigned to a chapter or section and add their notes and summaries. Teaches can also design guided questions or topics for students to fill in. Then they can help one another by adding onto someone else's notes or summary sections. Before a test or exam, students can then study everyone's wiki's.
