Based on the idea that the brain consists of hemispheres which control different types of behavior, this paper argues that the Puerto Rican school system is deteriorating because its emphasis on left hemisphere (quantitative) activities does not synchronize with Puerto Rico's cultural orientation toward the right hemisphere (qualitative activities). A chart is presented which enumerates features of the Puerto Rican school system according to left hemisphere activities. But Puerto Rican students, it is said, typically react negatively to English as a second language classes that are taught with a left hemisphere orientation, without positive feelings and warmth. Thus, advice is given on incorporating feelings and emotions into ESL teaching. Teachers are encouraged to establish an"intimate classroom atmosphere," and research findings are summarized in support of this idea. Four appendices are included: a diagram of the brain's hemispheres; a survey instrument used to gather students' feelings toward English classes; a poem; and song lyrics about living and changing.
