The way in which we process and therefore understand written and spoken texts is often described as either top-down or bottom-up. In our first language, we probably make use primarily of top-down processing.

Top-down and bottom-up are both strategies of information processing and knowledge ordering, used in a variety of fields including software, humanistic and scientific theories see systemicsand management and organization. In practice, they can be seen as a style of thinking, teaching, or leadership. A top-down approach also known as stepwise design and in some cases used as a synonym of decomposition is essentially the breaking down of a system to gain insight into its compositional sub-systems in a reverse engineering fashion.
Reading is one of the core components of early childhood education. From identifying letters to working on speech patterns, language acquisition in young children is dedicated to getting them to understand how spoken sounds and written words relate to each other and to cultivate a comprehension of reading. For current adults, recollections of their early years as students attempting to learn to read probably calls to mind memories of tracing letters, of sounding out letters, of beginning to sound out words and eventually reading books of increasing size, density and abstract content.

Effective teaching methods may be constrained by school curriculum, but educators can still devise instructional approaches based on the needs of their students. Some courses are taught better through lecture, while others may require class participation and direct interaction through laboratory and field-trips. Two common teaching methods are known as top-down and bottom-up, which take opposite approaches to providing students with an education.
