In the field of second language acquisition (SLA), "comprehensible input" (Krashen, 1985) has been considered a critical factor to help learners acquire foreign and second languages (L2). From this perspective, the notion of extensive or free voluntary reading (Day & Bamford, 1998; Krashen, 1993) has emerged that L2 learners should be given more…

A growing body of research suggests that the writing ability of international second language learners (IL2) and US-resident second language learners, also referred to as Generation 1.5 (G1.5), differs, despite a dearth of substantial empirical evidence supporting such claims. The present study provides much-needed empirical evidence concerning…

The purpose of this study was to determine if Morphological Instruction (knowledge of the Germanic, Latin, and Greek words, roots, and affixes of English) was an effective instructional approach towards accelerating the acquisition of spelling, vocabulary, and reading comprehension and closing at least a 6,000 word gap between English language…

This study investigated the longitudinal development of L2 vocabulary by 17 individual adult L2 learners in an English as a second language (ESL) instructed context over one academic year, combining a longitudinal case study design with two cross-sectional comparisons in order to enhance (a) detailed documentation addressing the idiosyncrasy of L2…

This dissertation examined the status of data-based research in applied linguistics through an analysis of published research studies in nine peer-reviewed applied linguistics journals ("Applied Language Learning, The Canadian Modern Language Review / La Revue canadienne des langues vivantes, Current Issues in Language Planning, Dialog on Language…

Previous studies revealed mixed results in terms of the relative effects of implicit and explicit feedback: some found that explicit feedback worked more efficiently than implicit feedback; others found no difference between the two feedback types. These contrasting results called for further investigations into this issue, particularly examining…

In recent years, researchers in the field of Second Language Acquisition (SLA) have become increasingly interested in the implications of sociolinguistic research for L2 learning. Among the many questions that arise are whether the development of sociolinguistic competence should be an instructional goal as early as the beginning level, and what…

Based on a mixed methods research design that included an examination of the impact of summer, case study analyses, and survey findings, English learners appear to have an advantage over their non-English learner peers in resisting summer loss and developing social competence. This study examined the effect of summer vacation on the oral reading…

Using responses from a survey of elementary teachers from the state of Ohio, this study analyzed the influences of teachers' professional training (both pre-service training and in-service professional development), teachers' attitude towards ELLs, teachers' bilingualism, schools' percent of ELLs, and schools' resources (both socioeconomic status…

Bilingual education has been a focus in Taiwan especially alter the educational reform in 2002 (Ministry of Education, 2003). With the educational reform, many teaching methods and approaches had been explored and implemented recently to enhance English as a Foreign Language (EFL) education. The traditional teaching approaches focused on the…

This research study compared the effects of three instructional methods--collaborative synchronous online communication, asynchronous online communication, and independent study as traditional in grammar translation method--in English reading comprehension. A quasi-experimental research design included pre and post reading comprehension tests for…
