Humans are lifelong learners. From birth onward we learn and assimilate what we have just learned into what we already know. Learning in the Geosciences, like all learning, can be catagorized into the domains of concept knowledge, how we view ourselves as learners and the skills we need to engage in the activities of geoscientists. As early as 1956 Educational Psychologist Benjamin Bloom divided what and how we learn into three seperate domains of learning.

Cognitive Domain

Cognitive Domain - This domain includes content knowledge and the development of intellectual skills. This includes the recall or recognition of specific facts and concepts that serve developing intellectual abilities and skills. There are six major categories, starting from the simplest behavior (recalling facts) to the most complex (Evaluation). The University of Washington's Geography Department website Major Categories in the Taxonomy of Educational Objectives has a detailed explanation of Bloom's Six Levels of Cognitive Development (more info).

Affective Domain

Affective Domain- How does one approach learning? With confidence, a can do attitude. The Affective domain includes feelings, values, appreciation, enthusiasms, motivations, and attitudes. The University of Dayton, School of Law Affective Domain website describes each catagory in the domain and provides illustrative examples and keywords for the cognitive, affective, and psychomotor domains.

Psychomotor Domain

Psychomotor Domain- The psychomotor domain includes physical movement, coordination, and use of the motor-skill areas. Development of these skills requires practice and is measured in terms of speed, precision, distance, procedures, or techniques in execution. For a more detailed treatment of this domain see the Penn State Teaching and Learning with Technology website Psychomotor Domain Taxonomy (more info).

Connecting Learning and Assessment

To see how assessments are built from these domains of learning and to learn how to build effective assessments go to the Hallmarks of Effective Assessment page.

Handbook I: Cognitive Domain. New York, Longmans, Green, 1956.

Cognitive Domain This domain focuses on intellectual skills and is familiar to educators. Bloom’s Taxonomy (knowledge, comprehension, application, analysis, synthesis, and evaluation) is frequently used to describe the increasing complexity of cognitive skills as students move from beginner to more advanced in their knowledge of content. The cognitive domain is the core learning domain. The other domains (affective, interpersonal, and psychomotor) require at least some cognitive component.

Cognitive domain - order ranking of 'synthesis' and 'evaluation' In my view, the question of the order of Synthesis and Evaluation is dependent upon the extent of strategic expectation and authority that is built into each, which depends on your situation. Hence it is possible to make a case for Bloom's original order shown above, or Anderson and Krathwhol's version of 2001 (which simply inverts levels 5 and 6). The above version is the original, and according to the examples and assumptions presented in the above matrix, is perfectly appropriate and logical.

I also personally believe the above order to be appropriate for corporate and industrial training and development if 'Evaluation' is taken to represent executive or strategic assessment and decision-making, which is effectively at the pinnacle of the corporate intellect-set. I believe inversion of Synthesis and Evaluation carries a risk unless it is properly qualified. This is because the highest skill level absolutely must involve strategic evaluation; effective management - especially of large activities or organisations - relies on strategic evaluation. And clearly, strategic evaluation, is by implication included in the 'Evaluation' category.

I would also argue that in order to evaluate properly and strategically, we need first to have learned and experienced the execution of the strategies (ie, to have completed the synthesis step) that we intend to evaluate. However, you should feel free to invert levels 5 and 6 if warranted by your own particular circumstances, particularly if your interpretation of 'Evaluation' is non-strategic, and not linked to decision-making. Changing the order of the levels is warranted if local circumstances alter the degree of difficulty. Remember, the taxonomy is based in the premise that the degree of difficulty increases through the levels - people need to learn to walk before they can run - it's that simple. So, if your situation causes 'Synthesis' to be more challenging than 'Evaluation', then change the order of the levels accordingly (ie., invert 5 and 6 like Anderson and Krathwhol did), so that you train people in the correct order.

In conclusion Bloom's Taxonomy is a wonderful reference model for all involved in teaching, training, learning, coaching - in the design, delivery and evaluation of these development methods. At its basic level (refresh your memory of the Bloom Taxonomy overview if helpful), the Taxonomy provides a simple, quick and easy checklist to start to plan any type of personal development. It helps to open up possibilities for all aspects of the subject or need concerned, and suggests a variety of the methods available for delivery of teaching and learning. As with any checklist, it also helps to reduce the risks of overlooking some vital aspects of the development required.

The more detailed elements within each domain provide additional reference points for learning design and evaluation, whether for a single lesson, session or activity, or training need, or for an entire course, programme or syllabus, across a large group of trainees or students, or a whole organisation. And at its most complex, Bloom's Taxonomy is continuously evolving, through the work of academics following in the footsteps of Bloom's early associates, as a fundamental concept for the development of formalised education across the world.

As with so many of the classical models involving the development of people and organisations, you actually have a choice as to how to use Bloom's Taxonomy. It's a tool - or more aptly - a toolbox. Tools are most useful when the user controls them; not vice-versa. Use Bloom's Taxonomy in the ways that you find helpful for your own situation.
