A statement of a learning objective contains a verb (an action) and an object (usually a noun).

  • The verb generally refers to [actions associated with] the intended cognitive process.
  • The object generally describes the knowledge students are expected to acquire or construct.
    (Anderson and Krathwohl, 2001, pp. 4–5)

The cognitive process dimension represents a continuum of increasing cognitive complexityfrom remember to create. Anderson and Krathwohl identify 19 specific cognitive processes that further clarify the bounds of the six categories (Table 1).

(clarifying, paraphrasing, representing, translating)


(illustrating, instantiating)


(categorizing, subsuming)


(abstracting, generalizing)


(concluding, extrapolating, interpolating, predicting)


(contrasting, mapping, matching)


(constructing models)


(carrying out)




(discriminating, distinguishing, focusing, selecting)


(finding coherence, integrating, outlining, parsing, structuring)




(coordinating, detecting, monitoring, testing)









(Table 1 adapted from Anderson and Krathwohl, 2001, pp. 6768.)

The knowledge dimension represents a range from concrete (factual) to abstract (metacognitive) (Table 2). Representation of the knowledge dimension as a number of discrete steps can be a bit misleading. For example, all procedural knowledge may not be more abstract than all conceptual knowledge. And metacognitive knowledge is a special case. In this model, "metacognitive knowledge is knowledge of [one's own] cognition and about oneself in relation to various subject matters . . . " (Anderson and Krathwohl, 2001, p. 44).

Table 2. The knowledge dimension — major types and subtypes
factual conceptual procedural metacognitive

knowledge of terminology

knowledge of specific details and elements

knowledge of classifications and categories

knowledge of principles and generalizations

knowledge of theories, models, and structures

knowledge of subject-specific skills and algorithms

knowledge of subject-specific techniques and methods

knowledge of criteria for determining when to use appropriate procedures

strategic knowledge

knowledge about cognitive tasks, including appropriate contextual and conditional knowledge


(Table 2 adapted from Anderson and Krathwohl, 2001, p. 46.).
