I am afraid my pre and post assessments for the experiment with my students are probably not of the expected format. I am just going to admit this - the pre and post assessments (which were pretty much identical) looked like a quiz. I did not have my students do a project or "create" anything so to speak, which would have been great and as it sounds many of you have been doing. I did not have enough time to give more than one day's class period for this experiment, and did not have time to fit in an actual project, although I'm sure it would have been valuable.  Even though my assessment was pretty much a quiz, I still definitely tried incorporating open-ended questions that required slightly higher order thinking skills than what would be on a typical mini-math quiz that others from my department and I would normally give.  For example, some of the questions were:

 “Explain what an inequality is in your own words.”

and

“What are two similarities between equations and inequalities?” (I also asked for 2 differences.)

and

“Describe the process for how to graph an inequality.”

My next task will be to try to make a rubric to accompany the quiz, which I do not think will be very easy, but I will figure it somehow.
