Bloom’s Taxonomy of Educational Objectives

Bloom’s taxonomy is a hierarchical model used for classifying learning objectives by levels of complexity and specificity. Bloom’s Taxonomy was created to outline and clarify how learners acquire new knowledge and skills. Though the original intention of the taxonomy was to serve as an assessment tool, Bloom’s taxonomy is effective in helping instructors identify clear learning objectives as well as create purposeful learning activities and instructional materials.

Bloom’s taxonomy emerged from a 1948 meeting of university educators – chaired by Benjamin Bloom – who brainstormed a theoretical model of learning that identified educational objectives to aid in the creation of testing items. The committee later expanded its initial framework to three learning domains:

Bloom

Bloom’s Taxonomy consists of three learning domains: cognitive, affective and psychomotor.

Cognitive Domain Heading link

Cognitive Domain

1

The cognitive domain went through numerous revisions before a finalized version was published (Bloom 1956).

The cognitive domain has been the primary focus in education and has become shorthand for Bloom’s Taxonomy as a result. The cognitive domain is made up of six levels of objectives. These levels are organized by hierarchy, moving from foundational skills to higher-order thinking skills.

In 2001 Anderson and Krathwohl revised Bloom’s levels from nouns to verbs, and this is the version of the taxonomy used today.

When revising Bloom’s Taxonomy in 2001, Anderson and Krathwohl also added the knowledge dimension to the taxonomy. The knowledge dimension consists of four dimensions, which are:

Based on this two-dimensional taxonomy, Anderson and Krathwohl developed a matrix for combining cognitive processes and knowledge dimensions which is shown to the left.

See the “How” section of this teaching guide to learn more about using the cognitive domain to craft learning objectives, assessments, and instructional materials and learning activities for your courses as well as how to implement the cognitive domain/knowledge dimension matrix when using Bloom’s Taxonomy in the classroom.

Affective Domain Heading link

Affective Domain

1

The affective domain was first published in 1964 (Krathwohl et al, 1964). The affective domain outlines skills and behaviors that correspond to attitudes and values and as the learner progresses through the levels of the affective domain, they become self-reliant and internally motivated. Learning objectives aligned to the affective domain tend to be the hardest to articulate initially and often appear difficult to assess at first glance. However, affective outcomes often represent the outcomes most closely related to deeper thinking and lifelong learning.

The affective domain contains five levels, from lowest to highest:

See the “How” section of this teaching guide to learn more about using the affective domain to craft learning objectives, assessments, and instructional materials and learning activities for your courses.

Psychomotor Domain Heading link

Psychomotor Domain

1

Bloom and his colleagues did not create subcategories for skills in the psychomotor domain, but other educators did (Simpson 1966, 1972; Dave, 1970; Harrow, 1972). The psychomotor domain includes physical movement, coordination, and motor skills. Development of these skills requires practice and is measured in terms of speed, precision, distance, procedures, or technical execution. For the purpose of this teaching guide, we will explore Simpson’s version of the psychomotor domain, which has the following seven levels:

HOW? Heading link

How can you use Bloom’s Taxonomy to craft learning objectives?

1

Bloom’s Taxonomy can help you write clear learning objectives, which are a description of what the learner must be able to do upon completion of an educational activity. A well-written learning objective outlines the knowledge, skills, and/or attitude the learners will gain from the educational activity and does so in an observable and measurable way.

More specifically, Bloom’s can help you identify the level, criteria, or standards for the knowledge, skills, abilities, competencies, attitudes, or values that your students are expected to be able to demonstrate.

For the cognitive, affective, and psychomotor domains, there are action verbs that align with each level. These action verbs are invaluable in crafting effective learning objectives.

2

Use the following steps to craft learning objectives using Bloom’s taxonomy:

  1. Select the domain (cognitive, affective, or psychomotor) for the learning objective you want to design.
  2. Determine at what complexity level you want students to demonstrate their learning.
  3. Select an action verb that is aligned to the domain level that you want students to demonstrate.

Consult the tables below to view action verbs that align with each level of the cognitive, affective, and psychomotor domains, as well as examples for each of the levels.

Cognitive domain Heading link

Cognitive domain

This domain is focused on intellectual skills such as critical thinking, problem-solving, and creating a knowledge base. The cognitive hierarchy consists of six levels, which span from simple memorization designed to build the knowledge of learners, to creating something new based on previously-learned information.

How can you use Bloom’s Taxonomy in the classroom?

There are many ways that Bloom’s can be applied to course planning to ensure effective instruction and student learning is occurring. Several approaches to lesson planning that build on Bloom’s Taxonomy are described below.

Expertise pathways

Expertise pathways

Expertise pathways involve using increasingly sophisticated cognitive processes to accumulate deeper understanding. This deeper understanding or expertise can be accomplished by moving through Bloom’s levels to explore a discrete learning topic or concept. The example below demonstrates expertise in the cognitive domain, focusing on a particular play script (Gershon 2013).
Remember the names and relationships of a cast of characters in a play A multiple-choice test designed to test the memory of learners.
Explain the main ideas of a play Write a short (1 page) paper summarizing the plot and most important events in the play.
Apply the main ideas/themes in the play to another context Write an advice column responding to one of the characters.
Analyze the roles of each character in the play and their relationships to each other. Write an analytical paper comparing the antagonists and protagonists of the play.
Evaluate the decisions of characters in the play, and support your evaluation with textual evidence. Write a response to one of the events in the play, either supporting or rejecting their actions on the basis of evidence from the play as well as personal opinion and projected/actual consequences of action.
Create a new and unique piece of writing using similar plot devices. Create a short story using similar plot devices in a new time or setting.
Differentiated instruction (all/most/some)

Differentiated instruction (all/most/some)

Differentiated instruction is the process of tailoring lessons to meet the needs, interests, strengths, and ability levels of individual students in the classroom. Gershon (2013, 2019) builds differentiation into instruction by splitting up a lesson objective into three outcomes as follows:

Gershon uses different levels of Bloom’s Taxonomy to define the all/most/some outcomes.

2

Alternatively, you can select a keyword from one of the top two levels of the taxonomy and then modify these to create increasingly complex learning objectives.

Three-part lesson Heading link

Three-part lesson

Another technique Gershon suggests is to divide the taxonomy into sections. For example, he splits the levels of the cognitive domain into three sections: remember and understand, apply and analyze, and evaluate and create. Then, he divides the lesson into three segments and focuses on one of the three sections of the domains in that lesson segment.

To implement Gershon’s technique, divide your lesson into three segments. Assign “remember and understand” to the first segment, “apply and analyze” to the second segment, and “evaluate and create” to the third segment of the lesson.

Below are example activities that can be used for each section of the lesson:

Section One: Remember and Understand

2

Section Two: Apply and Analyze

Section Three: Evaluate and Create

Alternatively, Crowe et al (2008) divide Bloom’s taxonomy into two sections referred to as lower order cognitive skills (LOCS) and higher order cognitive skills (HOCS) to better align assessments with learning activities in college-level Biology classes. LOCS comprise the first three cognitive levels of Bloom’s Taxonomy (remember, understand, and apply) whereas HOCS include the second three levels (analyze, evaluate, and create).

Another way to enhance the use of Bloom’s Taxonomy is by considering learning objectives simultaneously through Anderson and Krathwohl’s Two Dimensional Taxonomy: Cognitive Processes and Knowledge Dimensions Matrix. Richlin (2006) adapted this matrix for planning courses and lessons, which is shown in the table below. Examples of learning objectives that intersect the cognitive process and knowledge dimension are also detailed.
Cognitive Process Cognitive Process Cognitive Process Dimension Dimension Dimension
Remember: Retain, recall and recognize knowledge Understand: Translate and interpret knowledge Apply: Use knowledge in different situations Analyze: Break down information to look at relationships Evaluate: Make judgements based on evidence found Create: Compile information to generate new solutions
Factual Knowledge: basic elements to learn or solve problems in the discipline Remember + Factual List primary and secondary colors Understand + Factual Summarize features of a new product Apply + Factual Respond to frequently asked questions Analyze + Factual Select the most complete list of activities Evaluate + Factual Check for consistency among sources Create + Factual Generate a log of daily activities
Conceptual Knowledge: interrelationships between basic elements within a larger context Remember + Conceptual Recognize symptoms of exhaustion Understand + Conceptual Classify adhesives by toxicity Apply + Conceptual Provide advice to novices Analyze + Conceptual Differentiate high and low culture Evaluate + Conceptual Determine relevance of results Create + Conceptual Assemble a team of experts
Procedural Knowledge: methods in the discipline Remember + Procedural Recall how to perform CPR Understand + Procedural Clarify assembly instructions Apply + Procedural Carry out pH tests of water samples Analyze + Procedural Integrate compliance with regulations Evaluate + Procedural Judge efficiency of sampling techniques Create + Procedural Design efficient project workflow
Metacognitive Knowledge: awareness of how learning work in relation to one’s self Remember + Metacognitive Identify strategies for retaining information Understand + Metacognitive Predict one’s response to culture shock Apply + Metacognitive Use techniques that match one's strengths Analyze + Metacognitive Deconstruct one's biases Evaluate + Metacognitive Reflect on one's progress Create + Metacognitive Create a learning portfolio
