The assessment instrument is designed to measure students» understanding of energy at basic, intermediate, and advanced levels and draws on a bank of 372
multiple choice items targeting 14 different key ideas about energy forms, transformations, and transfers.
Although the specs may seem fairly intimidating, they lay out task models for developing different types of
items to address each
target — for example, task models for developing
multiple choice items, for developing
multiple choice items with
multiple correct answers, and for
items using hot text (for technology - enhanced
items where students highlight particular parts of texts to provide their answers).
