Webb’s Depth of Knowledge—Writing examples

Using Bloom’s Taxonomy (1956) is one way in which teachers can develop deeper thinking skills in students.  Bloom’s six cognitive skills start with easier thinking skills and move to more difficult, “higher order” thinking skills.

Bloom’s Level objective
knowing remembering facts
understanding showing understanding of facts
applying apply knowledge to new situations
analyzing examining information for component parts
synthesizing* creating something new from diverse elements
evaluating making judgments based on evidence or criteria

*Synthesizing is now called “creating,” and it has become the sixth, not fifth, level.

About 40 years after Bloom’s Taxonomy became known, a refinement of Bloom’s taxonomy called Webb’s Depth of Knowledge was developed (1997).  It has four levels.

DOK Level title of Level
1 recall and reproduction
2 skills and concepts
3 short-term strategic thinking
4 extended thinking


For teachers wanting to demand deeper thinking of their students, both Bloom’s Taxonomy and Webb’s DOK Levels can be used to design lesson plans.  Below are some writing assignments based on Webb’s Levels.




Level 1  Identify a list of important characters from the first Harry Potter novel.  Explain their relationship to Harry.

Level 2  Compare Harry’s, Ron’s and Hermione’s personalities.

Level 3  Explain how the opening scene in the first Harry Potter book lures readers into that book.

Level 4  Show how the authors of the first Harry Potter book and the first Percy Jackson book used a similar plot sequence to begin those books.

Level 2  Create a set of ten cards with a quote by a famous 20th century leader on one side and the leader’s name on the other side.
