Benjamin Devere White. Thesis: Thai/English language development
MA by Research (2012)
My study explored the correlation between the nature of language input when teaching a second language, and the nature of language development in the learner. I specifically focused on the extent to which using a student’s native language (Thai) in a second language learning environment (English) affected the development of English accuracy and fluency. My argument, based on previous studies, was that whilst exclusive English input would result in increased development in fluency, using both Thai and English would result in an increased development in accuracy. Results suggested that both methods of language input significantly advanced a learner’s accuracy and fluency, albeit to varying degrees. Thai usage was shown to be particularly advantageous with regards the acquisition of specific grammatical features English, whilst at the same time continuing to significantly advance speech-rate (an aspect of fluency) to levels comparable to using English alone. I also discovered that whilst participants exposed to solely English input demonstrated statistically significant accuracy gains, those made by participants exposed to Thai and English input were greater. Indeed, the sole advantage of English input over Thai and English input appeared to be an increased ability to hold the floor with a continuous utterance (a single aspect of fluency in my analysis). In light of these findings, it was discovered that the notion of adopting a one-size-fits-all approach to all language teaching is challengeable.
