3. Depth of Knowledge Classification of cognitive complexity
Nominative rather than taxonomy
Not about easy vs. difficult
Verb and it’s context
Considers complexity of both content and task required
Content: simple vs. complex data displays
Task: solving routine vs. non-routine problems using those data displays

4. Depth of Knowledge
“The DOK level describes the kind of thinking involved in the task, not whether it will be completed correctly. A greater DOK level requires greater conceptual understanding and cognitive processing by the students. Therefore, on average, students who reach greater DOK levels more regularly will have increased student achievement.”
Marconi, Smith, and Lombardi; “Depth of Knowledge: An Effective Tool for Education Students” in Shop Talk Vol. 4, No. 2 Spring 2009, The Southern Nevada Regional Professional Development Program.

5. Why Depth of Knowledge?
To ensure that the intent of the standard and the level of student demonstration required by that standard matches the assessment items (required under NCLB)
To assist in teaching to a level that will promote student achievement

6. DEPTH OF KNOWLEDGE - Level One
Recall and Reproduction requires recall of information, such as a fact, definition, term, or simple procedure, as well as performing a simple process or procedure. Level 1 problems involve only one step. A student answering a Level 1 item either knows the answer or does not: that is, the answer does not need to be “figured out” or “solved.”

7. DEPTH OF KNOWLEDGE - Level Two
Skills and Concepts/Basic Reasoning includes the engagement of some mental processing beyond recalling or reproducing a response. The content knowledge or process involved is more complex. These actions imply more than one step. Level 2 activities include making observations and collecting data.

8. DEPTH OF KNOWLEDGE - Level Three
Strategic Thinking/Complex Reasoning requires deep knowledge using reasoning, planning, using evidence, and a higher level of thinking than the previous two levels. The cognitive demands at Level 3 are complex and abstract. The multi-step task requires more demanding reasoning. In most instances, requiring students to explain their thinking is at Level 3. Other Level 3 activities include drawing conclusions from observations; citing evidence and developing a logical argument for concepts; explaining phenomena in terms of concepts; and using concepts to solve non-routine problems.

9. DEPTH OF KNOWLEDGE - Level Four
Extended Thinking/Reasoning requires high cognitive demand and is very complex. Students are required to make several connections – relate ideas within the content area or among content areas – and have to select or devise one approach among many alternatives on how the situation can be solved. Performance assessments and open-ended/constructed response assessment activities requiring significant thought will be Level 4.

10. Depth of Knowledge Level 1 — Identify this utensil.
Level 2 — Explain the function of the fork.
Level 3 — Identify two examples of when a fork would not be the best utensil for a type of food and explain why.
Level 4 — Design an investigation to determine the optimal number and length of tines for a salad fork.

This example is meant to provide a simple, academic example of the difference between the Webb levels. It is meant to mirror the basic labels provided for each level on the first Webb slide.
Level 1 – Recognizing and identifying a fork is at the factual recall level of understanding and application of the “concept” of a utensil.
Level 2 - Requires a relatively simple level of understanding of how a fork functions and the skill of translating that understanding into an explanation.
Level 3 - Requires some analysis and connecting to the understanding of forks and food to generate a conclusion and explanation for a real situation.
Level 4 – Requires a deeper and more involved application of the understanding of forks as part of a complex investigation.

11. Depth of Knowledge Level 1 — Identify the type of tree.
Level 2 — Explain the function of the leaves.
Level 3 — Explain how a drought might affect the growth of the tree.
Level 4 — Design an investigation of seedling growth to determine the best fertilizer for this type of tree.
This example is meant to provide a simple, academic example of the difference between the Webb levels. It is meant to mirror the basic labels provided for each level on the first Webb slide.
Level 1 – Recognizing and identifying a type of tree (coniferous, deciduous, etc.) is at the factual recall level of understanding and application of the “concept” of a tree.
Level 2 - Requires a relatively simple level of understanding of how a tree functions and the skill of translating that understanding into an explanation.
Level 3 - Requires some analysis and connecting to the understanding of trees to generate a conclusion and explanation for a real situation.
Level 4 – Requires a deeper and more involved application of the understanding of trees as part of a complex investigation.
