Problem Centered Inquiry Model

I liked this one, but I am still not sure when I should stop and let the kids carry on. I found that my AP class could handle this model much better than my regular Spanish I students which are 9th and 10th graders. It seems that my lower level students need more structure, but then when I think about it. Solving problems like this on a regular basis will increase their ability to approach and solve problems. I just need to take smaller steps than what I do with my AP class.
