-brain functions in many ways as two brains
-brain composed of two hemispheres
Left hemisphere of the brain:
-vocal, analytical side, which is used for verbalization and for reality-based and logical thinking.
Right hemisphere of the brain:
-emotional, visual-spatial, nonverbal
-thinking processes using the right brain are intuitive, subjective, relational, holistic
* corpus callosum: connector between the two hemisphere
Each hemisphere gathers in the same sensory information but handles the information on different ways. One hemisphere may take over and inhibit the other in processing information or the task may be divided between the two sides with each handling the part best suited to its way of processing information. Educators need to know which side of the brain is better equipped for certain kinds of tasks and, thus, what is the most effective way to present information to leaners who may have a dominant brain hemisphere. Brain hemisphericity is linked to cognitive learning style or the way individuals perceive and gather information to problem solve, complete assigned tasks, relate to others and meet the daily challenges of life
Recent advances in brain research is mainly due to neuroimaging methods such as positron emission tomography (PET) and magnetic resonance imaging (MRI), provide the educator with the new knowledge on how brain works.
McIntoch (1998): Proposes a general hypothesis that learning and memory are emergent properties of network interactions
Sylvester (1995, 1998): Reported on the research that has led to a better understanding of the functions of the brain and individual learning differences
Iaccino (1993): Provided more detailed accounts of the clinical evidence that has contributed the left right dichotomy of the brain.
LEFT HEMISPHERE FUNCTIONS
Thinking is critical, logic, convergent, focal
Prefers talking and writing
Responds to verbal instructions and explanations
Relies on language in thinking and remembering
Solves problems by breaking them into parts, then approaches the problem sequentially, using logic Good organizational skills, neat
Likes stability, willing to adhere to rules
Conscious of time and schedules
Algebra is the preferred math
Not as good at interpreting body language
RIGHT HEMISPHERE FUNCTION
Thinking is creative, intuitive, divergent, and diffuse
Prefers drawing and manipulating objects
Responds to written instructions and explanations
Relies on images in thinking and remembering
Solves problems by looking at the whole, the configuration, then approaches the problem through patterns, using hunches Loose organizational skills, sloppy
Like change, uncertainty
Frequently loses contact with time and schedules
Geometry is the preferred math
Good at interpreting body language
Free with emotions
Brain Preference Indicator: a set of questions used to determine hemispheric dominance. The BPI instrument can reveal a general style of thought that results in a consistent pattern of behaviour in all areas of the individual’s life. More information about the BPI can be found in Whole-Brain Thinking by Wonder and Donovan (1984)
Statistics show that most learners have left brain dominance and that approximately 30% have right brain dominance.
Consideration. . .
1. First, the educator must think of the brain from perspective of such things as mental process, feelings and desires 2. Second, the culture in which one lives is important in the development and expression of one’s learning style. 3. Lastly, educators bring a set of values when teaching and learners bring a set of values when learning, both of which determine what...
