In our school, the most beneficial web based technology tool is the class blog. I like the opportunity to read my classmates' work . It is a great way to compare my skill to theirs. I can also gather a new perspective of prompts and assignments.
The blog is also a very convenient way for teachers to post what absentees missed during the class period. It gives a mass detailed instruction without need of much repetition. Students have no excuse anymore to get behind on homework.
