There are three levels of permissions within Google Sites: Owner, Editor and Viewer. If you create a site, you'll be the owner, which means you have full permissions to modify design and content.
You can share the site with editors, for example your students. They can only be allowed to edit existing pages; they cannot change the design of the site. You can also share the site with viewers, for example parents. They can only view the site and are not permitted to make any changes.
In school you can use Google Sites in many different ways...
You can use it as a web page. At my school each class has its own site, where the children explain what we're doing in school. The children use the site as a class blog and they can update the blog and contribute with their thoughts. The parents are viewers, which mean they can read all the important information. We use this page instead of "veckobrev".
Each child also has their own personal site. It is used by students as a digital portfolio featuring their best work. They upload PDFs, Word files or other documents that they are proud of.
You can also use Google Sites as a wiki. First you need to share your site with the students, and invite them to be owners or editors. Then they can edit the page you gave them access to. They can communicate with each other and comment on each other's texts.
When we work with different themed, for example Östersjöväldet or with a book project, we make a site which holds all the information about the work. The students then publish their work om the site and they can easily comment on each other's work.
