PBL versus WebQuest

Dear All,
In almost all the post I find that the importance of PBL and WebQuest were discussed. Christos wrote " 
PBL and Webquests give students the opportunity to see language for what it is: not an end in itself, but a tool to express themselves."
Ahmad wrote"  
PBL promotes autonomous learning"
For PBL Nina quote from Confucius philosophy: "Tell me, and I will forget. Show me, and I may remember. Involve me, and I will understand."
Hassina raised teaching literature through PBL. I was also a student of literature. I also think that if the students of literature could prepare a PBL, it would have become easier to them.  
Bruno aptly wrote "I think Andreja aptly tried to give the nuance between PBL and WebQuests in the following sentences: "WebQuests have an element of inquiry and curiosity, project-based activities are about gaining hands-on experience"."
Zlatka wrote "Now I know that the real project-based work doesn't only consist of writing on a topic, but integrates different skills and abilities."

Mary Jow wrote" The Project-Based Learning (including WebQuests) can change the teacher-student relationship for the students would express themselves freely,look forward to the teacher's lessons and work on projects with greater enthusiasm making learning an exciting experience hence a mutually beneficial relationship. "

Raphael wrote"  Now for the teacher , the use of PBL or Web Quest will give him or her more a feeling that his or her students are learning by themselves, they become more knowledgeable about the given issues, they know more about technology and maybe the most important, they solve complex problems."
Aleyda wrote the following long sentence on PBL  " 
To motivate students, I try to develop projects that are relevant or will be relevant in their teaching career or contribute in one way or another one to their language, academic or cognitive skills (to be more reflexive,for example)like video-taped lesson plans, reading-based drama projects, adapting stories and fairy tales and making their own books, elaborating recipes and organizing food exhibits (restaurants),drawing their neighborhood map, oral presentations on research-based topics, elaborating bulletin boards on language or academic topics, public singing, learning portfolios, etc."

I think this week we are on the verge of getting perfect ideas on PBL and WebQuest.
WebQuest is time consuming, hard but interesting, pleasurable and enjoyable.
Thanks,
Mahamud
