Rather than constituting a problem for students and educators, the growing diversity in U.S. classrooms necessitates and encourages the development and use of diverse teaching strategies designed to respond to each student as an individual.
Damage to a discrete part of a the brain in the left frontal lobe (Brocaâs area) of the language-dominant hemisphere has been shown to significantly affect use of spontaneous speech and motor speech control. Words may be uttered very slowly and poorly articulated.
Language is a bit more complex; it is believed that most language processing happens in the temporal lobe, but Broca's area in the left frontal lobe is associated with spoken language, and Wernicke's area (the main area of the brain associated with understanding language) is actually between the parietal lobe and the temporal lobe.
