There are now many ways to create blogs for students. Some schools are using EDSBY where groups can be made and internally a blog can be formed within the school.
Public and free programs such as wordpress can be used, or if you or your board can put some money into it, squarespace is extremely easy to use. The benefit of being a public forum is that parents can access and view their childrenÕs work, other teachers can share space, students that want to review topics have them readily accessible, students that want to move ahead can do so; the scope of a project can be easily presented; the goal of having your work published on a blog will drive more detail students themselves.
In addition, teachers may choose to contribute to, or students contribute to or the course utilizes existing public blogs such as Enterprise in Space Academy.
