How students can better overcome language and reading problems thanks to the plastic brain and teacher know-how.
The brain is an experience-dependent organ. From our very earliest days, the brain begins to map itself to our world as we experience it through our senses. The mapping is vague and fuzzy at first, like a blurred photograph or an un-tuned piano. However, the more we interact with the world, the more well-defined our brain maps become until they are fine-tuned and differentiated. But each person’s map will vary, with some sensory experiences more distinct than others depending on the unique experiences and the clarity and frequency of the sensations he or she has experienced.
Educators can positively influence students’ learning by understanding how the brain is shaped by their early experiences—and how it can be rewired and reorganized to work more quickly and efficiently.
The Plastic Brain and the Critical Period
Brain plasticity, or neuroplasticity, refers to the brain’s ability to change with experience. In infancy and early childhood, a brain is so “plastic” that its structure is easily changed by simple exposure to new things in the environment. This time is sometimes called “the critical period,” or “the sensitive period.” [NOTE: the term ‘critical period’ although popular a couple of decades ago it is rarely used anymore because we understand plasticity better and realize new skills can be acquired long after the early developmental period, hence it is not really “critical”.]
Consider, for example, how babies easily learn the sounds of language and words by listening to their parents speak. Inside the brain, what this learning looks like is the brain actually reorganizing itself to change its own structure and create new sound maps that reflect the sounds of their native language. These sound maps are then interconnected with other maps and nodes to form interconnected networks so sound can be linked to meaning.
Networks can be expansive. For example, the sound map needed to recognize the word “pen” might first be connected to the meaning connoting a writing instrument, but over time, “pen” might be part of a network for comprehending “pen” as a verb meaning to write, then part of a word referring to legibility, “penmanship” and perhaps later to farm regions, like a pig pen. Networks will also develop to allow words to be used in grammatical sentences then organized for reading.
