Developed model, borderline, related, contrary, invented, and illegitimate cases according to Walker and Avant’s Method in regard to “Education”.
Identify a model case. A model case is a real-life example of the use of the concept that includes all the critical attributes of the concept (defining attributes identified in Part 1 of the assignment). The model case can come first, or can be developed simultaneously with the attributes, or it can emerge after the attributes are tentatively determined.
Identify borderline, related, contrary, invented, and illegitimate cases.
Borderline case: contains some of the critical attributes but not all of them
Related case: related to the concept but does not contain the critical attributes
Contrary case: not the concept
Invented case: constructed, but not existing in real life
Illegitimate case: improper use of the concept
