ASSIGNMENT: Defining a Technical Term
Below are three examples of definitions of technical terms. This assignment asks you to
evaluate these technical terms, then write one of your own using a technical term from
your field of study.
Read the following three examples of technical definitions, which have been taken from
web sites that are designed to provide information for general readers, and then evaluate
each example using the questions given below all three examples. Please use complete
sentences, and discuss and expand any “yes” or “no” answers.
Example A: Definition of pigment.
A pigment is any substance that absorbs light. The color of the pigment comes
from the wavelengths of light reflected (in other words, those not absorbed).
Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all
wavelengths of visible light except green, which it reflects to be detected by our
eyes. Black pigments absorb all of the wavelengths that strike them. White
pigments/lighter colors reflect all or almost all of the energy striking them.
Pigments have their own characteristic absorption spectra, the absorption
pattern of a given pigment.

Example B: Definition of photosynthesis.
Photosynthesis is the fundamental process that maintains life on earth. Living cells
convert food into energy and structural components. Almost all organisms derive this
food, directly or indirectly, from the organic compounds formed within plants during
photosynthesis. The stored energy in these compounds is essential for growth, repair,
reproduction, movement, and other vital functions. Without photosynthesis, not only
would replenishment of the fundamental food supply halt, but the earth would eventually
become devoid of oxygen.
Example C: Definition of Sickle Cell Anemia
You will find an example of an extended definition at the following site:

Evaluation Criteria:
Evaluate each technical definition based on the criteria listed below. Please explain your
“yes” and “no” answers.
1.
2.
3.
4.
5.
What is the type of definition (parenthetical, sentence, expanded)?
Is the type of definition suited to its purpose and user’s needs?
Does the definition adequately classify the term?
Does the definition clarify, rather than obscure the meaning?
Is the definition adequately developed?
6. Is the definition unified and coherent?
7. Are visuals, if used, employed adequately and appropriately?
This task is worth 21 points (7 points per each example (A,B,C)).
Grading criteria: accurate identification of type of definition and assessment of the
construction of the technical definition based on the questions given above.
