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.
Speech and language are mainly attributed to parts of the cerebral cortex, which is one portion of the telencephalon. Motor portions of language are attributed to Broca's area within the frontal lobe. Speech comprehension is attributed to Wernicke's area which lies at the temporal-parietal lobe junction.
