Paper Abstract:
|
Wainer and Thissen (1994) suggested that there are three purposes for large-scale testing; 1) as a contest and 2) as a
measurement of single schools and of school systems and 3) as an instrument of social change. This paper will propose a
fourth purpose for large-scale testing, 4) as a source of feedback to inform teaching. The first three approaches may be
appropriate for summative assessment but could be inadequate for formative assessment because of the information that is
lost in the scoring procedure. A means for recovering this lost information Response Spectrum Analysis and
Interpretation (RSAI) combines adaptations of several existing technologies to capture the performance status of students
from both the right and the wrong answers. This paper presents a procedure that bypasses the problem of linear
dependency among test data to expose the dynamics of answer selection processes at a diagnostic level. Samples of
response patterns from actual students are presented, analyzed statistically using an adaptation of the multinomial
procedure and interpreted using students reported selection processes. |
