Three design challenges Three design challenges Hard-to-assess standards in the
domain of interest e.g., inquiry science skills
Efficient and valid design and development of complex tasks e.g., scenarios, simulations
Accessibility of tasks for diverse learners varying perceptual and expressive
capabilities valid use of assistive technology,
modifications, alternative assessments

How Design Patterns Support Thinking about the Assessment
Argument
The design pattern is organized around Focal KSAs. They will be
involved in the Student Model, although there may be other KSAs
that are included in the target of inference (e.g., Model Revision—but what models, what context?).

Additional KSAs play multiple roles. You need to think about which ones you really DO want to include as targets of inference
(validity) and which ones you really DON’T (invalidity).

Potential Work Products help you think about what you want to capture from a performance –product, process, constructed model, written explanation, etc.
Can also call attention to demand for Additional KSAs, & avoid alternative explanations for poor performance
