2. Depth of Knowledge (DOK) DOK stands for “Depth of Knowledge.”
DOK is one way administrators, teachers, and parents can understand the objectives in terms of the complexity of what students are expected to know and do.
DOK is a system for categorizing cognitive demand (Bloom is a system we are all familiar with).
Developed by Norman L. Webb. 2 Webb Model: Provides analysis of the degree of intersection of state assessments and content standards, which combines qualitative expert judgments and quantified coding and statistical analysis. The Council worked with Norman Webb in developing the model.
Webb Model
The model developed by Norman Webb from the University of Wisconsin, provides a reliable set of procedures and criteria for conducting alignment analysis studies, which combine qualitative expert judgments and quantified coding and analysis of standards and assessments. The product of the analysis is a set of statistics for each standard and grade on the degree of intersection, or alignment, between the content embedded in state content standards and the content in state assessments. The Webb model has been used in alignment studies with more than 10 states, partly through SCASS collaborative projects managed by CCSSO. The model has been used for language arts, mathematics, science, and social studies.
Following the training process, four to six reviewers, including teachers and content specialists, individually identify the content standard objectives that match each assessment item. They first determine the 'depth of knowledge' required by each objective or benchmark of the content standards being analyzed, and code each using one of four levels of knowledge: (a) recall, (b) skill/concept, (c) strategic thinking, (d) extended thinking. Operational definitions and labels vary somewhat by subject. Second, reviewers determine the objective or benchmark represented by each item or task on the state assessment being reviewed, and they rate the level of knowledge necessary for a student to successfully complete the item or task.
Norman L. Webb is a senior research scientist with the Wisconsin Center for Education Research and the National Institute for Science Education.Webb is a mathematics educator and evaluator who leads the Institute's work on strategies for evaluating reform and rethinking how we evaluate mathematics and science education, while focusing on the NSF's Mathematics and Science Partnerships.His own research has focused on assessment of students' knowledge of mathematics and the alignment of standards and assessments. Webb also directs evaluations of curriculum and professional development projects.

3. Webb’s Depth of Knowledge Level 1 Recall
Recall of a fact, information, or procedure, rote response, follow a set procedure, typically involves one step
Level 2 Basic Reasoning
Use information or conceptual knowledge, make decisions about how to approach the question or problem, use two or more steps that go beyond recall or simple procedure
Level 3 Strategic Thinking
Requires reasoning, developing a plan or sequence of steps, has some complexity, more than one possible answer based on more demanding reasoning
Level 4 Extended Thinking
Requires an investigation, time to think and process
multiple conditions of the problem or task,
relate ideas within and among content
4. 4 Final Jeopardy is always DOK 1 (recall) even though the level of difficulty is often quite high.Final Jeopardy is always DOK 1 (recall) even though the level of difficulty is often quite high.

7. Why Depth of Knowledge? Mechanism 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)
Provides cognitive processing ceiling (highest level students can be assessed) for item development

Webb’s Depth of Knowledge levels:
Recall and Reproduction: Level 1
Skills & Concepts: Level 2
Strategic Thinking: Level 3
Extended Thinking: Level 4 8
9. Recall : Level 1 9 Level 1 only requires students to demonstrate a rote response, use a well-known formula, follow a set procedure (like a recipe), or perform a clearly defined series of steps.

13. Strategic Thinking: Level 3 13 The complexity does not result only from the fact that there could be multiple answers, a possibility for both Levels 1 and 2, but because the multi-step task requires In most instances, requiring students to explain their thinking is at Level 3; requiring a very simple explanation or a word or two should be at Level 2.The complexity does not result only from the fact that there could be multiple answers, a possibility for both Levels 1 and 2, but because the multi-step task requires In most instances, requiring students to explain their thinking is at Level 3; requiring a very simple explanation or a word or two should be at Level 2.

16. Extended Thinking: Level 4 16 Many on-demand assessment instruments will not include any assessment activities that could be classified as Level 4. However, standards, goals, and objectives can be stated in such a way as to expect students to perform extended thinking. “Develop generalizations of the results obtained and the strategies used and apply them to new problem situations,” is an example of a Grade 8 objective that is a Level 4. The extended time period is not a distinguishing factor if the required work is only repetitive and does not require applying significant conceptual understanding and higher-order thinking.

20. Teaching with DOK
Every objective in our frameworks has been assigned a DOK level.
State assessments are designed so that the test items match the DOK levels of the objectives.
DOK 1, 2, and 3 items are on the state assessments.
Instruction needs to be designed at the same level as the DOK specified by the objective if students are to be adequately prepared for the state assessments.
Teachers need to examine each objective to ensure that they are teaching at the appropriate
DOK level.

22. Depth of Knowledge is Not a verb
The Depth of Knowledge is NOT determined by the verb.
DOK is determined by the context in which the verb is used and the depth of thinking required.

23. 23
24. DOK is Not About Difficulty Difficulty only tells us how many students can answer a question correctly.
*How many of you know the definition of the word knowledge? DOK 1 Recall
If most of you know the definition, it is an easy question.
*How many of you know the definition of the words panegyrize? DOK 1 Recall
If most of you do not know the definition, it is a difficult question.
25. DOK is About Complexity Level 1 requires students to use simple skills or abilities.
Level 2 includes the engagement of some mental processing beyond recalling.
Level 3 requires some higher level mental processing like reasoning, planning, and using evidence.
Level 4 requires complex reasoning, planning, developing, and thinking over an extended period of time.
26. DOK is Not a Performance Level Descriptor Advanced
Proficient
Basic
Minimal
27. PLDs are about Difficulty Advanced: Students at the advanced level are able to perform at a high level of difficulty, complexity, or fluency as specified by the grade-level content standards.
Proficient: Students at the proficient level are able to perform at the level of difficulty, complexity, or fluency specified by the grade-level content standards.
Basic: Students at the basic level are able to perform some of the content standards at a low level of difficulty, complexity, or fluency as specified by the grade-level content standards.
28. 6th Grade Vocabulary PLD Advanced: Justify the use of context clues used to determine meaning of multiple meaning words or to infer meaning of figurative language. Justify vocabulary usage based on appropriateness for context and purpose. Justify selection of word choice based on use of reference materials.
Proficient: Apply knowledge of roots and affixes (com-, ex-, il-, mid-, under-, sub-, -ance, -ence, -ive, -en) to determine the meaning of multi-syllabic words. Apply expansive knowledge of words and word meanings to communicate. Use context clues to determine the meanings of multiple meaning words and the figurative meanings of text. Use reference materials to evaluate word choice in a variety of texts and to determine meaning. Analyze and evaluate vocabulary usage based on appropriateness for context and purpose.
Basic: Identify of roots and affixes in multi-syllabic words; identify and produce grade-level appropriate synonyms, antonyms, and homonyms; identify figurative language in text of increasing length, complexity and difficulty.

32. Why DOK is important? MCT2, Algebra I Test, and English II Test are tied to specific Depth of Knowledge Levels.
DOK on these tests will range from Levels 1-3.
Teachers at all grade levels need to understand all DOK levels.
Instruction, assignments, and classroom assessment must incorporate the expectation of rigor for students associated with the DOK levels of all objectives for that grade and content area.
33. Where do we start? Examine the framework for your subject area and/or grade level. Note the DOK levels for each objective.
Examine the PLD for your subject area and/or grade level. Note the differences among advance, proficient, and basic.
Examine the Test Items Specifications for your subject area and/or grade level. Note the way each objective is assessed.
34. DOK in your Classroom Teach students how to answer DOK 2 and 3 questions by modeling using think-alouds
“I do. We do. You do.”
Add one or two high level questions on class assignments and homework
Do a Level 3 or 4 activity each week
35. DOK in your Classroom Start with the competencies and objectives
Create assessments using DOK that are modeled after Test Item Specifications
Design instruction based on DOK and PLD
Assess at regular intervals
Use assessment results to focus instruction and to make interventions
36. DRAFT Language Arts Blueprint
37. DRAFT Math Blueprint
38. Test Taking Strategies Emphasize reading the question/prompt thoroughly.
Underline key words, numbers, and phrases that may be important when solving the problem or answering the question.
If the question has multiple steps, break it down and do one step at a time.
