This is an extremely basic template of a PBL project using Google Sites. The person who created the template included sections for daily plans and parts of the project. The great thing about the template marketplace in Google Apps is that if I wanted to use this template myself and edit it, I could select the button at the top that says "use this template." In many ways, Google Apps offers chances for teachers to learn from each other and avoid reinventing the wheel unnecessarily.
The author here discusses some ways to use tools in Google Apps to standardize some of the project-based learning process. This post is one in a series about Google Apps and PBL and you can find others by selecting posts in the author's "Google Apps" categoy. I'm not a fan of standardization, but when it comes to managing the PBL process, some useful forms and templates are great to have. One she mentions is a "team task sheet" for planning each member's role in the project as well as observation, question, and research forms. This post deals with using Google Sites not just as a replacement for the usual "project poster," but as a more living space for the PBL group and its project.
