As a long time Moodle user I have casually wondered what constructivist might mean. I have read some wikis etc on the matter but frankly am little the wiser from a practical POV.
Recent experiments with Sugar suggest that I need to understand this approach a bit more if I am to use Sugar in a class situation. So my questions is..
What exactly do you do to teach constructivistly (?) if you are a real teacher with a real bunch of students.
In the hope of generating something helpful rather than a bunch of semiotics(!)
The first and simplest thing I can tell you is: ask some good questions, one that require thinking to answer. You've done that here already 
My second simple tip is to look for any opportunity where your students can contribute by building something. Again, this discussion is an example, but you could also start a wiki page with some structuring headings and ask people to help build it up as a reference.

Yes, good questions and allow students to construct something... That's the basics.... The idea is that they need to construct their learning... not just take in information and give it back.
Here is a website which might help you: http://www.intel.com/education/tools/index.htm
At the bottom of the page under Student Curriculum there are listed 4 projects which are case studies of Project Based learning done with the INTEL Teach program. They might help you to understand how this might work... When I finished the course, I put my project into a Moodle class so I could share with other teachers at our district.
Hope that helps.
