http://www2.lv.psu.edu/ojj/courses/discrete-math/topics/02proofs.html WebThis theoretical paper sets forth two "aspects of predication," which describe how students perceive the relationship between a property and an object. We argue these are consequential for how students make sense of discrete mathematics proofs related to the properties and how they construct a logical structure. These aspects of predication are …
