An unrelated answer shows the task was not understood, which is the Prestructural level.

Multistructural responses have many facts; relational responses integrate them, so the difference is quantity versus integration.

Applying an integrated understanding to a new context and generating a novel idea is the Extended Abstract level.

Showing how several ideas interact to form an integrated whole is the Relational level.

Several correct but disconnected facts indicate the Multistructural level.

Using only one relevant aspect is the Unistructural level.

Listing several facts without relating them is the Multistructural level.

Transforming information into a diagram that represents its meaning is a form of Understanding (interpreting).

Explaining a concept and giving an example of it shows Understand (explaining and exemplifying).

Being able to define a concept without explaining it in one's own words is Remember.

The revised taxonomy rises from Remember to Understand, Apply, Analyze, Evaluate, and Create.

Generating ideas, planning and producing an original product are the processes of Create.

Checking and critiquing are the two processes of the Evaluate category in the revised taxonomy.

Identifying assumptions, separating relevant from irrelevant evidence and seeing how components are organized is Analyze.

Understanding is grasping a principle, while applying means using it to carry out a procedure in a new situation.

In the revision, Knowledge became Remember, Comprehension became Understand, and Synthesis became Create (nouns changed to verbs).

Judging against explicit standards is Evaluation.

Breaking an argument into parts and showing how they relate is Analysis.

Identifying a definition from alternatives is recall of information, which is the Knowledge level.

If nearly everyone answers nearly every item correctly, the items are too easy, so the level of difficulty needs reconsideration.

Rejecting a test for excessive time, equipment and cost questions its usability (practicality).

When different examiners score identical answers differently, scoring is influenced by personal judgment, so objectivity is compromised.

Consistent scores indicate reliability, scoring free from examiner bias indicates objectivity, and low cost and ease of administration indicate usability.
