Abstract
The effect of response format on diagnostic assessment of students' performance on an algebra test was investigated. Two sets of parallel, open-ended (OE) items and a set of multiple-choice (MC) items—which were stem-equivalent to one of the OE item sets—were compared using two diagnostic approaches: a “bug” analysis and a rule-space analysis. Items with identical format (parallel OE items) were more similar than items with different formats (OE vs. MC).
