1) The document discusses Webb's Depth of Knowledge (DOK) framework for classifying standards, objectives, tasks and assessments based on the complexity of thinking required. 2) DOK has four levels - recall and reproduction, skills and concepts, strategic thinking, and extended thinking. It is important to ensure standards, instruction and assessments are aligned to the DOK levels. 3) While verbs used may signal complexity, the real determiner is the cognitive demand of the task - what students are asked to do. DOK is not about difficulty but about the depth of understanding required.

- 17. DOK is NOT... • a taxonomy (Bloom’s) • the same as difficulty • about using “verbs”
- 18. It’s NOT about the verb... The Depth of Knowledge is NOT determined by the verb (Bloom’s Taxonomy), but by the context in which the verb is used and the depth of thinking required.
- 19. Verbs are not always used appropriat ely. . . Words like explain or analyze have to be considered in context. • “Explain to me where you live” does not raise the DOK of a simple rote response. • Even if the student has to use addresses or landmarks, the student is doing nothing more than recalling and reciting.
- 20. DOK is about what f ollows t he verb. . . What comes after the verb is more important than the verb itself. “Analyze this sentence to decide if the commas have been used correctly” does not meet the criteria for high cognitive processing.” The student who has been taught the rule for using commas is merely using the rule.
- 21. Same Verb—Three Different DOK Levels DOK 1 Describe three characteristics of metamorphic - rocks. (Requires simple recall) DOK 2- Describe the difference between metamorphic and igneous rocks. (Requires cognit ive processing t o det ermine t he differences in t he t wo rock t ypes) DOK 3- Describe a model that you might use to represent the relationships that exist within the rock cycle. (Requires deep underst anding of rock cycle and a det erminat ion of how best t o represent it )
- 22. DOK is about int ended out come, not difficult y DOK is a reference to the complexity of mental processing that must occur to answer a question, perform a task, or generate a product. • Adding is a mental process. • Knowing the rule for adding is the intended outcome that influences the DOK. • Once someone learns the “rule” of how to add, 4 + 4 is DOK 1 and is also easy. • Adding 4,678,895 + 9,578,885 is still a DOK 1 but may be more “difficult.”
- 23. DOK is not about difficult y... • Difficulty is a reference to how many students answer a question correctly. “How many of you know the definition of exaggerate?” DOK 1 – recall If all of you know the definition, this question is an easy question. “How many of you know the definition of prescient?” DOK 1 – recall If most of you do not know the definition, this question is a difficult question.
- 24. DOK is about complexit y • The intended student learning outcome determines the DOK level. • Every objective in the science and mathematics frameworks has been assigned a DOK level. • Instruction and classroom assessments must reflect the DOK level of the objective or intended learning outcome.

- 27. What is Dept h of Knowledge (DOK)? • A scale of cognitive demand (thinking) to align standards with assessments • Based on the research of Norman Webb, University of Wisconsin Cent er for Educat ion Research and t he Nat ional I nst it ut e for Science Educat ion • Defines the “ceiling” or highest DOK level for each Core Content standard for the state assessment • Guides item development for state assessments
- 28. Webb’s Four Levels of Cognit ive Complexit y • Level 1: Recall and Reproduction • Level 2: Skills & Concepts "To be, or • Level 3: Strategic Thinking not to be: that is the question" • Level 4: Extended Thinking
- 29. DOK Level 1: Recall and Reproduct ion • Requires recall of information, such as a fact, definition, term, or performance of a simple process or procedure • Answering a Level 1 item can involve following a simple, well-known procedure or formula
- 30. Recall and Reproduct ion DOK Level 1 Examples: • List animals that survive by eating other animals • Locate or recall facts found in text • Describe physical features of places • Determine the perimeter or area of rectangles given a drawing or labels • Identify elements of music using music terminology • Identify basic rules for participating in simple games and activities
- 31. Skills/ Concept s: DOK Level 2 • I ncludes t he engagement of some ment al processing beyond recalling or reproducing a response • I t ems require st udent s t o make some decisions as t o how t o approach t he quest ion or problem • Act ions imply more t han one ment al or cognit ive process/ st ep
- 32. Skills/ Concept s: DOK 2 Examples • Compare desert and tropical environments • Identify and summarize the major events, problems, solutions, conflicts in literary text • Explain the cause-effect of historical events • Predict a logical outcome based on information in a reading selection • Explain how good work habits are important at home, school, and on the job • Classify plane and three dimensional figures • Describe various styles of music
- 33. St rat egic Thinking: Level 3 • Requires deep underst anding exhibited through planning, using evidence, and more demanding cognit ive reasoning • The cognitive demands are complex and abst ract • An assessment item that has more than one possible answer and requires students to j ust ify t he response would most likely be a Level 3
- 34. DOK Level 3: St rat egic Thinking Examples: • Compare consumer actions and analyze how these actions impact the environment • Analyze or evaluate the effectiveness of literary elements (e.g., characterization, setting, point of view, conflict and resolution, plot structures) • Solve a multiple-step problem and provide support with a mathematical explanation that justifies the answer
- 35. DOK Level 3 Examples • Develop a scientific model for a complex idea • Propose and evaluate solutions for an economic problem • Explain, generalize or connect ideas, using supporting evidence from a text or source • Create a dance that represents the characteristics of a culture
- 36. Ext ended Thinking: Level 4 • Requires high cognit ive demand and is very complex • Students are expected to make connections, relate ideas within the content or among content areas, and select or devise one approach among many alternatives on how the situation can be solved • Due to the complexity of cognitive demand, DOK 4 often requires an extended period of time
- 37. Ext ended Thinking: DOK 4 Examples • Gather, analyze, organize, and interpret information from multiple (print and non print) sources to draft a reasoned report • Analyzing author’s craft (e.g., style, bias, literary techniques, point of view) • Create an exercise plan applying the “FITT (Frequency, Intensity, Time, Type) Principle”

Editor's Notes
- Many Factors Contribute to the Achievement Gap The achievement gap stems from both home- and school-based factors. It exists before students ever cross the school threshold, and this disadvantage can greatly affect their educational progress and success. Students living in poverty tend to be less successful in school The National Center for Education Statistics (NCES) conducted a national longitudinal study of children entering kindergarten in 1998. It found that students whose mothers had not graduated from high school, whose families received public assistance or were headed by single parents, and/or whose parents’ primary language was not English were disproportionately represented among low performers. All of these factors correlate highly with poverty. Although poverty does not cause low achievement, it does set the conditions for it. Students living in poverty are more likely to be exposed to factors known to affect achievement, such as: Lack of access to proper nutrition, health care, and decent housing; and Exposure to substance abuse and high-crime communities. Risk factors have a synergistic effect on school performance—children with one risk factor typically do not fare as well as those with none. Children with two or more of these factors generally lag far behind those with only one. Not to be overlooked are social factors and processes that play an enormous role in determining a child’s later learning and future academic success. High family stress levels, maternal depression, little interaction with the child, and family illiteracy all have a negative impact on a child’s developing capacity to learn. Because African Americans and Latinos in California represent disproportionate numbers of children living in poverty, they are also more likely to begin school at a disadvantage. Cultural factors can also affect student performance The cultural background of both students and educators can also play a role in student achievement. First, it is well documented that some educators have lower academic expectations for students of color. This has been a topic of much discussion over the past decades, and attempting to change teachers’ attitudes and practices is at the heart of the standards-based reform movement. Beyond this complex and pervasive problem is another issue—how the values and expectations of students’ backgrounds and communities influence their attitudes about schooling and academic performance. The extent to which culture affects attitude and achievement is a politically sensitive and controversial subject. The variables most consistently correlated with low student achievement are poverty and low parent education level. Yet even among students coming from poor families, some cultural groups generally outperform others in school. And among wealthier students, some groups of students—for example, middle-class African American males—consistently lag behind their white classmates. Researchers differ regarding the causes of these gaps. Temple University professor Laurence Steinberg has found that although Asian students associate negative life consequences with poor school performance, African American and Hispanic students do not. University of California-Berkeley professor John Ogbu argues that community-based “folk theories” contribute to self-defeating behaviors. (An example of a folk theory would be that because of the history of discrimination against African Americans, even those who work hard will never reap the rewards that whites do.) Others theorize that the efforts of even the most supportive parents and communities can be undermined by teens’ need for peer approval. Schools can play a role in narrowing the gap A driving force in education reform for decades has been optimism that schools can help students overcome the disadvantages they bring with them into the classroom. For more than 40 years, researchers have conducted extensive investigations to determine which school factors influence student achievement. However, results of this research point to complex interactions among multiple factors, indicating that the solutions are neither simple nor straightforward. The state and federal movement toward a standards-based approach to school improvement begins with the assumption that all students can meet high academic expectations. Based on that assumption, a fundamental strategy has been to shed light on the achievement gaps that exist between groups of students. Evaluating what combination of educational strategies, resources, capacity-building, and incentives can contribute to better academic performance among low-performing students continues to be a focus for educators and researchers. Meanwhile, policymakers have crafted accountability systems that put increased pressure on the schools and school districts that are currently falling short in helping all their students meet rigorous new achievement goals. http://www.edsource.org/stu_achivegap.html
- It is important to understand that the DOK classification scheme was adopted because it does not require an inference about the skill knowledge, and background of the student, but is based solely on what is being asked cognitively. The Depth of Knowledge classification scheme classifies assessment items or tasks, not students or student work. This classification scheme was developed originally for assessment items. The intention for use was to align learning objectives with assessments. The Depths of knowledge were developed by Norman L. Webb at the Wisconsin Center for Education Research and the National Institute for Science Education. Florida’s Next Generation Standards were rated for depth of knowledge to help align learning goals with instruction and assessment.
- 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.
- The levels of low, moderate, and high are those used by FCAT and are based on a similar scheme developed by the National Assessment for Educational Progress. These 3-level schemes differ only slightly from Norman Webb’s 4-level scheme. In the FCAT 3-level scheme, Webb’s DOK levels 3 and aspects of level 4 are combined in the “high.”
- Florida’s Next Generation standards were rated in terms of DOK by pulling together a large group that included DOK experts, scientists, science curriculum specialists, teachers, and the Department of Education. This process was facilitated by FCRSTEM and FDOE Office of Math & Science. The result: All of Florida’s Math and Science Next Generation Standards have been assigned a DOK rating. These ratings are available through the Florida Standards Database.
- In general, the ratings of the benchmarks set a ceiling for assessment. Thus, a benchmark that is rated at a moderate level, could be assessed at a low level or a moderate level. Ideally, the benchmark rating aligns with the assessment level – this was a purpose for rating benchmarks. This helps teachers know to what depth students are expected to master the benchmarks. It helps to build a common understanding of the expectations of the benchmark, though a great deal of interpretation and consensus building is required.
- This example item was provided by the FCAT developers as an example of a moderate complexity item. The item asks students to bring together understanding of multiple forces (friction and gravity) along with the properties of the materials that the blocks are made of, and finally to make a comparison. The requirements to bring together understanding of properties and forces and then to make a comparison between the different blocks are what make this item a moderate complexity task.
- This example item was provided by the FCAT developers as an example of a high complexity item. This item takes the requirements of the last item up one more step by requiring students to consider an additional variable, the inclination of the plane and therefore requires them to consider multiple variables and explain, in terms of forces, how these variable affect the movement of the blocks. The student is required to predict the effect of a change within the system which requires them to think beyond the image provided. Keep in mind that the moderate level item that this item was built upon can be raised to a high level in many ways. What are some other ways that one could bring the moderate level task up to a high level task? An example would be to provide a set of data and then require students to explain the experiment.
- This example item was provided by the FCAT developers as an example of a low complexity item. The item asks students to recall/recognize which force causes objects to move down an inclined plane. If a student identifies the correct force, the answer is found. It does not require further processing of the information.
- Tasks, standards, and assessments are classified in terms of DOK to ensure alignment between these activities and to ensure that a common understanding of these activities is established for the teachers, students, and administrators. These alignments can be used to indicate how well instruction or a test reflects the intended standards. These alignments also help to ensure that standards, instruction, and assessment result in student understanding that goes deeper than “an inch”
