Understanding how written and oral information connects is a crucial skill for us as college students. We constantly encounter information from a variety of sources (texts, articles, presentations), and being able to see the interaction between them is key to fully understanding the material.
An example I could give is when, in methodology classes, I read about different learning theories. Each describes and analyzes the types and mechanisms of learning in a somewhat abstract way. Then, in the corresponding lecture, the professor presents a series of case studies of students studying based on these theories.
If we focus o on memorizing concepts and treating each theory as separate stories, the crucial connection will be lost. However, if we recognize that the lecture offers concrete examples to illustrate abstract theories, our understanding is greatly enriched.
