Julie, I am up in Calgary giving my talk and thought about something that has been bothering me about the GCI. We see essentially no improvement with high pretesters which either means they didnlt improve their conceptual understanding or that the 15 item subtest is simply not sensitive enough (i mean if they get 12 right on the pre test there really isn't much room for improvement). For those using the gci for research this can be very limiting. Should we think about maybe doing a 45 quetsion 'research-grade' gci subtest for researchers that has more high end sensitivity (especially if we want to study more advanced learners)?
