In education, a microtheme is a very short essay. (For example, one required to be 100-500 words in length or to fit on a index card). Often an exercise unto itself, it can also be used in writing courses to incrementally build up toward a larger paper. Microthemes allow for quick grading, such as A+/A/A-. Writing skill can be improved by writing often and in this case, by practicing writing the same thing in different ways and with different combinations of words.
