Second Language Acquisition in Early Childhood Research Paper by Research Group

Based on a substantial amount of empirical research conducted on second language acquisition, it has been theorized that learners are best able to achieve the critical skill of learning a second language at some point fairly early in their maturational development. This claim is known as the "critical period hypothesis," which postulates that there is some maturational period for language learning that maximizes one's degree of proficiency in the language beyond that of other maturational periods. This study examines whether the critical period during which children are best able to learn English as a second language is before six years or age. To this end, the study compares the English proficiency levels of two groups of eighth grade ESL learners, a group that had begun to learn English before they were six years of age and a group that had begun to learn English after six years of age. Because the nature of language required in school is complex, a fairly complex assessment was made of English proficiency, namely English proficiency was assessed using the Quick-Start in English Written Language Assessment (QSE). The study shows that there are higher proficiency levels for those children who learned English before six than for those children who learned it after six years of age.
