Fig. 3. A typical distribution of students at the close of the RTOI and one viable ranking scenario.
When the question/answer phase of the RTOI is complete, I ask students to look and their positions and consider what grades are appropriate. A point I emphasize in my testing as well as teaching is that the distinction between "student" and "teacher" roles is not rigid - at times I ask students to become "teachers" and at times I become a "student". Although I could easily take the initiative and assign an "A" to all those who have progressed to zone IV, a "B" to those in zone III, a "C" to those who have inched to zone II, and a "D" to those who are stuck in zone I, sometimes I engage in a process of negotiated grading with students. I regard grading as more than a matter of mathematical formulas. In the process of determining grades, I look for gaps in the distribution curve which suggest natural demarcation points, but also consider the impact that the grading process it is likely to have on students. Although there is a clear-cut demarcation between zones III and IV, the division between other zones is less distinct. There is a good chance that I would offer S
