Effectiveness of on-line corpus research in L2 writing: Investigation of proficiency in English writing through independent error correction.

Description: Second language (L2) researchers and teachers have increasingly come to believe that using a computer-based corpus can be extremely helpful in the language classroom. The purpose of this study is to examine whether corpora can be used outside of the classroom in order for students to improve their essays independently. No previous study has tried to examine students' essays in relation to corpus use so that this study is exploratory. Seven international students wrote five essays on specific topics and then corrected their errors through corpus research. Two experiments were conducted with different students and followed three steps: receiving information about how to use the BYU COCA, writing and correcting, and interviews with students. I examined quantitatively the number and types of errors that students were able to correct in two experiments and reported qualitatively on students' interview responses.

Formulaic sequences in English conversation: Improving spoken fluency in non-native speakers.

Description: Native speakers often ignore the limitless potential of language and stick to institutionalized formulaic sequences. These sequences are stored and processed as wholes, rather than as the individual words and grammatical rules which make them up. Due to research on formulaic sequence in spoken language, English as a Second Language / Foreign Language pedagogy has begun to follow suit. There has been a call for a shift from the traditional focus on isolated grammar and vocabulary to formulaic sequences and context. I tested this hypothesis with 19 L2 English learners who received 5 weeks of task-based instruction and found substantial progress in oral fluency only for the experimental group. Differences between pretest and posttest oral fluency were examined by looking at the learners' speech rate and their mean length of run. Subjective evaluation of fluency by 16 native English judges confirmed the calculated measures.

Investigating incidental vocabulary acquisition in ESL conversation classes.

Description: This study examined incidental receptive and productive vocabulary gains within conversation-class interactions. Eleven Mexican learners of English attended four videotaped conversation lessons where 40 target words were incorporated in different types of exposure. Stimulated recall interviews with students highlighted the effect of cognates, learners' access to passive vocabulary, and use of their vocabulary knowledge in learning related words. Posttests revealed a correlation between frequency and receptive/productive gains. Mean scores showed that words mentioned with synonyms were learned most often, followed by task-essential words and last those mentioned without explanation. A two-way ANCOVA revealed main effects for cognates, and a statistical interaction between cognate status and types of exposure. A statistical correlation was found between receptive and productive gains. Aptitude scores correlated with productive gains but not with receptive gains. The results provide implications for ESL teachers who consider incidental learning of vocabulary within their conversation lessons.
