Bloom’s revised taxonomy names six kinds of cognitive work: remember, understand, apply, analyze, evaluate, and create. It helps teachers plan goals that move beyond recalling words to using them to reason and make something meaningful.

In a language project, students might interpret authentic sources, compare perspectives, weigh evidence, then create a bilingual neighborhood guide or podcast for a real audience. The categories guide planning; learners can move among them as a project unfolds.

Hess’ matrix pairs Bloom’s cognitive processes—the kind of thinking—with Webb’s Depth of Knowledge—the complexity and scope of the work. Together, they help teachers ask whether a task calls for recall, strategic reasoning, or sustained transfer, rather than judging rigor by an action verb alone.

For example, “describe a celebration” may invite recall. A richer project asks students to compare first-hand and secondary sources, consider whose perspectives are represented, select evidence, and create a bilingual exhibit for a defined audience. The matrix is a planning lens; the task itself determines its demand.
