2.2.1 Bloom’s Taxonomy—Expanding its Meaning

by Paula Bobrowski (Associate Dean for Research and Faculty Development, Auburn University)

This module expands the usefulness of Bloom’s taxonomy beyond its original intent of clarifying educational objectives to help faculty prepare better-designed courses, achieve more student-centered implementation, and establish outcomes-oriented evaluation criteria. Bloom’s taxonomy is explored from a historical perspective and examined for its applications in Process Education. Pacific Crest’s adaptation of Bloom’s taxonomy includes five different “levels of learner knowledge.” Each of these is defined and illustrated with key words and questions for use in designing curriculum and instructional materials.
 
Table 1  Description of Bloom’s Taxonomy
of Educational Objectives

Knowledge of terminology, specific facts, ways and means of dealing with specifics, conventions, trends and sequences, classifications and categories, criteria, methodology, abstractions in a field, principles and generalizations, and theoretical structures

Comprehension in translation, interpretation, and extrapolation

Application of concepts in the use of abstraction in particular and in concrete situations

Analysis of elements, relationships, and organizational principles

Synthesis of ideas in the production of unique communications and plans

Evaluation leading to judgments about the value of materials and methods for given purposes

A Description of Bloom’s Taxonomy and its Significance

Educational objectives indicate what students should attend to and put effort into learning; they are “explicit formulations of the ways in which students are expected to be changed by the educative process” (Bloom, 1956). Bloom’s taxonomy provides a well-accepted pedagogical framework for classifying vast numbers of educational objectives into useful structures. Benjamin Bloom’s pioneering work on learning was initiated in 1948, when he headed a team of educators and psychologists investigating three major learning domains: cognitive, affective, and psychomotor. Over the last half-century, the theoretical framework produced by this team has facilitated analyses of learning objectives classification, criteria for performance-based learning, and levels of mastery in learning (Simon, 2000).

To the extent that the goal of education is the diffusion of knowledge through learning, a description of Bloom’s taxonomy represents a seminal work in developing and implementing high quality instruction. There are six different levels in the cognitive domain of factual and conceptual knowledge progressing from elementary to complex. As demonstrated in Table 1, the levels include knowledge, comprehension, application, analysis, synthesis and evaluation.

Evolution of Bloom’s Taxonomy

Over the past 40 years Bloom’s work has been translated into more than twenty languages and has provided a basis for test design and curriculum development. Many modern interpretations of Bloom’s taxonomy are found in the literature. Recently Anderson and Krathwohl (2001) expanded the single dimension of the original taxonomy into a two-dimensional framework consisting of factual/conceptual knowledge and cognitive processes. High quality educational objectives combine both elements as seen in the following example: “The student will learn to distinguish (cognitive process) among confederate, federal, and unitary systems of government (knowledge).” Apple and Krumsieg (2001) clarified some of the definitions found in the original taxonomy by viewing it in terms of transferable knowledge that progresses in complexity through the six levels. The most basic level, using Apple and Krumsieg’s labels, involves information (knowledge in Bloom), followed by knowledge (comprehension), knowledge skill (application), problem solution (analysis), new knowledge (synthesis), and finally evaluation (peer-reviewed knowledge). This model of learning has supported the development of a learning process methodology for efficiently and effectively advancing the level of student knowledge (Krumsieg & Baehr, 2000).

There is also extensive educational research aimed at moving beyond the cognitive domain in formal education by focusing more attention on the affective and psychomotor domains (Shank 1994; Tinto, 1994; Bobrowski & Molinari, 1992). Although this is not the focus of this module, it is important to be aware of these developments. Tinto (1993) and Shank (1994) have published significant works in this area, arguing that academics must change the way teaching is performed, by paying special attention to the intrapersonal and interpersonal contexts of learning. Tinto examined learning communities in depth, while Shank promotes the perspective that the only way learning occurs is “by doing.”

Levels of Learner Knowledge

Bloom’s taxonomy has been adapted and transformed by Apple and Krumsieg (2001). According to their Learning Process Methodology, five levels of learner knowledge are observable in college classrooms. These are defined in Table 2 and represent increasing complexity in the way students formulate, connect, and present their thoughts. Information acquisition occupies the lowest level and is typified by memorization of information. Conceptual understanding represents the next higher level and is the result of combining information elements to achieve understanding and meaning. Application is the ability to apply knowledge in a new context. Working expertise is the ability to understand the logical constructs and apply knowledge without expert prompting. Research is the goal of graduate study and is the ability to create novel discoveries from basic elements and logical constructs. The “evaluation level” in Bloom is considered separately as part of assessment, which can take place at any level.

Brookfield (1987) argues that learning is promoted by asking questions that challenge students’ understanding at the appropriate level. Good questions can also stimulate students’ curiosity and allow the teacher to probe current understanding as well as assess the effectiveness of past instructional activities (Eggen & Kauchak, 1988). Inquiry as a learning method requires active participation both by the students and teachers. For this reason, Table 2 integrates Barton’s (1997) hierarchy of critical thinking questions with the levels of learner knowledge. The combination of these two concepts creates a useful tool for teachers to use in classroom applications. It provides key words and questions that are appropriate to ask students at each level of learning and demonstrates the link with Bloom’s taxonomy of educational objectives.

Classroom Application

Questions and key words in Table 2 can be used to set performance criteria for learning activities, to verify pre-requisite knowledge, and to measure achievement against learning outcomes. Prompts in this table also provide guidance on which thinking skills are most developmentally appropriate for cultivation and suggest possible avenues to challenge students at the next higher-level of knowledge. For example, introducing methodologies and studying their elements at Levels One and Two is a particularly effective way to accelerate the creation of transferable knowledge at Levels Three and Four.

Fundamental to all aspects of educational processes is the knowledge that results from experiencing applications of knowledge. To gain additional insights into the connections between the learning process and Bloom’s taxonomy, see the modules 2.3.3 Classification of Learning Skills, and 2.3.7 Learning Processes through the Use of Methodologies. These modules clarify the role of educators in building stronger transferable skills at increasingly higher levels of learning.

Concluding Thoughts

This module provides an overview of Bloom’s taxonomy and subsequent work, which offers a rational and holistic approach to defining academic quality. Table 2 is designed around Bloom’s levels of knowledge model to help illuminate appropriate teaching/learning processes for different performance capabilities and to focus attention on the detail that is expected of students in order to accomplish learning objectives. The related components of the table will help faculty ask better questions, define clearer expectations for assignments, and compose exam questions that are matched to specific levels of learning outcomes.
