Bloom’s Taxonomy: Levels of Understanding

Let's add an envelope generator to our synthesizer below. This envelope will cause the volume of the sound from the oscillator to fade in gradually, sustain, and then drop off sharply. We'll use an ADSR envelope generator connected to the level input of our VCA:

 Included at this thought level are the processes of analysis, synthesis, and evaluation.

The following three cognitive levels are based on a modified version of Bloom’s taxonomy (Taxonomy of Educational Objectives, Bloom et al., 1956). Bloom's taxonomy describes six cognitive categories: Knowledge, Comprehension, Application, Analysis, Synthesis, and Evaluation. For ease of classification, the six cognitive domains have been collapsed into three.

Label for Level of Understanding: ..

Krathwohl and Bloom created a taxonomy for the affective domain that lists levels of commitment (indicating affect) from lowest to highest.

3. - Application refers to the ability to use learned material in new and concrete situations. This may include the application of such things as rules, methods, concepts, principles, laws, and theories. Learning outcomes in this area require a higher level of understanding than those of comprehension.

What Exactly Is “Understanding?” And How Do We …

There are some problems with our synthesizer design—not the least of which is that because we have no way of controlling the volume of the oscillator, our instrument is always making sound! In order to fix this problem, we need to add a module called a Voltage Controlled Amplifier, or VCA. The function of a VCA is to raise or lower the volume, often called or , of a signal. Essentially, a VCA is a volume knob. Oscillators and other sound generating modules are always making sound, and VCAs are what keep the level down when you're not playing.

High levels of stress, even over relatively short periods and in vastly different contexts, tend to produce similar results: prolonged healing times, reduction in ability to cope with vaccinations, and heightened vulnerability to viral infection (21). The long-term, constant cortisol exposure associated with chronic stress produces further symptoms, including impaired cognition, decreased thyroid function, and accumulation of abdominal fat, which itself has implications for cardiovascular health. The bottom line is that both episodes of acute stress and more prolonged stressful circumstances precipitate lower levels of general health, and exposure to such stress should be minimized. In the most extreme cases, Cushing’s Syndrome, characterized by dangerously high cortisol levels, can result. Those afflicted with Cushing’s experience rapid weight gain, hyperhydrosis, and hypercalcemia, along with various psychological and endocrine problems (22).

Stress is unavoidable. Our bodies are designed to react to our environment in an effort to preserve homeostasis. Arming ourselves with an understanding of the mechanisms, agonists, and antagonists of the stress response, however, positions us to minimize stress and its impact on our minds and bodies. It is both a blessing and a curse that the HPA axis evolved to be so sensitive to factors like circadian rhythm, caffeine, and alcohol. We are experts at maintaining homeostasis but often novices at managing stressful circumstances. The good news is that stress levels rest largely on our own behavior and decisions and that we can optimize our bodies’ responses to stress based on how we live our daily lives.
