In order to guide our students through the process, we use KidBlog to create a forum where students can reflect on their own thinking throughout each phase of the process.  In doing so, students can learn how the project comes together over time and look back to see how far they have come by the end of the year.  This blog is also a helpful guide for teachers to see each step in the process from the vantage point of a student.  A sample blog is available here.
