Neurolinguists have recently demonstrated that language learning is a
multifaceted process which activates simultaneously the modes of perce
ption of the left and right cerebral hemispheres. Current brain resear
ch therefore points to the need for ''bimodal'' foreign language instr
uction - that is, eclectic pedagogical practices which stimulate in ta
ndem the brain's two hemispheres. This paper evaluates the ''bimodalit
y'' of the theoretical model accepted by advocates of proficiency-orie
nted instruction and recommends that further research be conducted to
ascertain the effects on student proficiency of a ''bimodal'' pedagogi
cal approach.
