Thus, the attributes represent different aspects of meaningful learning, specifically differentiation and integration of concepts. Hence construct validity is established. Propositions establish meaningful relationships between concepts. Hierarchy refers to the breaking down of the superordinate concept into valid levels, from most general to most specific. The branches are the broadest concepts or subconcepts which flow from the superordinate concept.
Examples are the most specific differentiation of the subordinate concepts.
Degree of conceptualization indicates how well the superordinate concept and its connected subordinate concepts are understood. It also addresses naive or faulty conceptions. The scoring with this rubric did not allow for aufficient discrimination, i.e., ratings fell between the points on the scale. The scores did not appear to be very consistent and there was also a need for greater discrimination within the scale. Therefore, the rubric was expanded to a 4 to 0 scale.
