Your character not only believes that we construct knowledge as schemas in our heads but that the very best way to develop those schemas is to build (construct) something real. By building something, one must exemplify and apply what one know, and it is through this application of knowledge that real understanding is developed. Building does not have to be the engineering of robots or bridges but rather the creation of any intellectual product (e.g., multimedia presentations and computer programs). By constructing something, the knowledge is made one’s own. Your character disagrees with the notion of sitting and listening to a lecture or just talking about ideas, preferring learners to be active doers that applies knowledge to generate a tangible artifact of learning.
