Presents a design framework that incorporates integrated structures for modeling knowledge and skills, designing tasks, and extracting and synthesizing evidence. Illustrates these ideas in the context of a project that assesses problem solving in dental hygiene through computer-based simulations. (SLD)

The consequences in terms of misclassifications of students that would occur by replacing the constructed-response portion of the Advanced Placement (AP) examinations in economics with more multiple-choice items were studied. The 1991 AP examinations in micro- and macroeconomics were used. Computer simulation found that a small but statistically…
