[Rasch] psychometrics to measure dynamicity

Dear Dr. Commons,
Thank you for your question. What I am interested in is to see how Dynamic assessment (DA) would affect (1) learners' performance on the same items over time and (2) the hierarchical relation of the items in each time performance. There are certain learners whose performance remained constant (either correct or incorrect) there are also some whose performance changes either for good or bad.
I hope I am clear now.
Thank you again for your help in advance.

Please expand.  Do you look at a series of interviews and then Rasch the stage scores?
My Best,

 For example, in Dynamic assessment, where tutor attempts to provide feedback 
(first implicitly then explicitly) according to learner's responsiveness, the trait is 
not static but dynamic

A Piagetian interview is one such dynamic technique; our research shows pretty 
good Rasch evidence...
