Measuring Up: Prototypes for Mathematics Assessment
Characteristics of the medium response:
The response demonstrates that the map and its scale are generally well understood. The principal difference between the high and medium response is that the latter does not consider many possible locations for the lightning strikes. One point equidistant from A and C is found for question 5, but the answer to question 6 is "no."
Characteristics of the low response:
The low response is characterized by thinking that is limited to one point or one distance at a time. Thus, while question 1 through 4 may be answered satisfactorily (although with limited justifications), no points that are equidistant from A and C are found.
