Is There a Good Webquest to Teach Kids to Think?

I used a webquest last year for my Grade 6 students. It was approved by a provincial government body for use in public schools. I live in a different province, but thought that, since it was recommended for my grade level I would try it. The preview left me with questions. Navigating through it left me thinking that it had really good potential, but that being approved for grades 5-8 was too broad a range. I noted the questions I thought students would have trouble with and also noted that they would need lots of instruction to know how to pull important text from a paragraph or a page of details. Anxious to broaden their experience and mine, I proceeded with optimism and hope.

In the end, students derived a lot of meaning from the experience and provided feedback to me that was positive. As a teacher, I was exhausted because of the amount of intervention needed to teach it. I also felt the conviction that I wouldn't use it again for my age grouping of students because I felt [I provided feedback to the organization that produced the webquest, too] that it needed to be more kid friendly. Thinking back on it now, however, I would recommend it be simplified with fewer questions that would require critical thinking skills to be employed. As it was, students had to read a lot of text, withdraw important details, and synthesize information only to a degree. I would like them to have to make a decision based upon their learning.

What do you think? What experiences do you have? What webquests might you recommend I, or others, visit and/or use?
