Teasers are commonly composed of 5-7 items of this kind, which provide infor-
mation that cannot be provided by multiple-choice items. For example, they can
help teachers answer questions like the following:
1. What concepts is this student working with?
2. How does she understand these concepts?
3. What is her line of reasoning?
4. How well does she explain her thinking?
In addition to helping students consolidate new knowledge, items of this kind
provide an opportunity to hone essential life skills like reasoning and writing.
Scoring and reports.
After students submit their responses to a set of teaser items,
they are directed to a coding page on which they are asked to match their own
responses to options in a series of “pull-down” menus. These menus function as
low-
inference
rubrics, and can be used effectively by students, teachers, and researchers.
