Brain Bulletin #1: Simplifying the Brain

Brain Bulletin #1: Simplifying the Brain

This is the first in a series of Brain Bulletins to help educators understand the research and studies done about the brain as it pertains to reading.

The first step in connecting teaching to the research is to simply understand that reading is not

natural. This means, the brain does not naturally begin to read by just being exposed to text

Reading involves multiple parts of the brain; the pathways and connections need to be built and

strengthened in the brain through our instruction.  Teaching reading does involve science,

because there is actual evidence and data about how the brain processes language, written

text, and encoding (writing).

 

Reading and the activity of the brain can be seen

through studies using different methods such as

MRIs, neuro-imaging, and non-invasive brain

stimulation.

Full-disclosure: None of these are my area of expertise, but I believe in science.  By looking at the studies and research done, hopefully we can help our littles more effectively.

 

Let’s review the general areas of the brain and their

simplified role in reading:

These do not include some sub-areas that have more specific tasks.  These will be explained in future Brain Bulletins.

 

 

 

 

 

Frontal Lobe is responsible for: articulation and phonemic awareness

Broca’s Area is responsible for: muscles of speech, pronunciation, discrimination in speech sounds

 

Temporal Lobe is responsible for: meaning, connection to prior knowledge, context

Although the graphic shows a picture, this is a bit more complex.  The basic way to explain is to say that this is where the brain finds meaning.  A person might hear or read the word “can” and the brain uses the context and background knowledge to decipher if “can” represents the tin receptacle or the verb form.  In a simple sense, this shows us how important knowledge, comprehension, and vocabulary acquisition are to the main goal of reading.

 

Parietal Lobe is responsible for:  word analysis, connecting spoken sounds to the corresponding phonics structures

 

Occipital Lobe is responsible for: visual/word form, BUT this area is sensitive to “letter patterns, rather than visual features of individual letters” (Source of orthographic mapping)*

 

The brain is a complex machine and still requires research and studying, but there is sufficient and valid data to inform some of our practices.   By understanding how the brain processes, or does not process, information and input, we can gear our teaching towards the most effective ways to support our students…. or at least understand the “why” behind some of our practices.

    This is very interesting.
    It’s helpful to have the information about the source of the data.
    It will encourage teachers & parents to base their practices on facts.
