The primary purpose of blog is to facilitate interaction between a teacher and his or her students. This is possible because a blog is a dynamic tool which can be easily updated or transformed as necessary to meet the needs of a science or math class.
The integration of blog technology in a class requires an investment of time. Because of this commitment, additional evidence is needed to support the integration this technology in a science or math class curriculum.
Have you ever wanted to create short "how to" video for your students to use for homework, remembering facts, and solving math problems.
