In the first website this one teacher talks about how she used a blog in her english class. She gave the children a certain book to read and then go and post a blog about what they thought, and then to comment on some of their students blogs. This was a really good site because this also gave the students knowledge of how to use the computer and internet to post blogs. It also gives the students an opportunity to interact with the students outside of the classroom.
The second article it talks how blogs are used in the science class room in the Middle and High school classrooms. In this website and blogs, they share different types of resources for the students or teachers to use. Have different videos and links that go along with the lessons in the class. It also allows students to put post and comments about the homework assignments also.
