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. A top-down teaching style focuses on providing students a large view of a subject, immersing them in the big picture without explaining the components that make up the subject. For example, in an English as a Second Language class, a top-down approach would begin by immersing students in all aspects of learning English immediately, including writing, reading and pronunciation.

Top-Down vs. Bottom-Up: What's the Difference?

It considers those factors, along with the speech sounds, and does its best to interpret what was said.

Bottom-up processing is an explanation for perceptions that start with an incoming stimulus and working upwards until a representation of the object is formed in our minds. This process suggests that our perceptual experience is based entirely on the sensory stimuli that we piece together using only data that is available from our senses. In order to make sense of the world, we must take in energy from the environment and convert it to neural signals, a process known as sensation. It is in the next step of the process, known as perception , that our brains interpret these sensory signals.
