This study investigated whether the framework of writing for English learners should be guided by the well-established reading-writing relation or by the receptive and productive nature of literacy skills. The writings of 209 advanced English learners in Korea were analyzed in relation to receptive and productive vocabulary knowledge and reading comprehension while controlling for writing fluency. Two sets of structural equation models were fitted: (1) productive skills (productive vocabulary and writing fluency) mediating receptive skills (receptive vocabulary and reading) and (2) reading mediating receptive and productive vocabulary knowledge. The results supported the second model in which reading completely mediated the contribution of receptive and productive vocabulary to writing. Although there were no direct effects of receptive and productive vocabulary knowledge, both had significant indirect effects on writing through reading and writing fluency. These results show that reading has a strong direct effect on writing above and beyond vocabulary, and that vocabulary knowledge contributes to writing development through reading.

The current study examined the potential contribution of advanced Korean EFL learners’ writing abilities to their reading comprehension abilities. A total of 191 college students participated in this study and were tested on writing and reading comprehension abilities as well as other literacy-related measures including listening comprehension, textreading fluency, and knowledge of vocabulary to control for their effects. In order to account for different aspects of writing and reading comprehension abilities, multiple measures of reading and writing abilities were adopted. The Structural Equation Modeling (SEM) analyses demonstrated that the advanced Korean EFL learners’ English writing abilities had a significant effect on their reading comprehension abilities when other relevant literacy skills were controlled for. Furthermore, their writing abilities mediated the relationship between vocabulary knowledge and reading comprehension abilities. These results highlight the important pedagogical implications on the critical role of writing abilities in enhancing the reading comprehension abilities of L2 learners.

This study investigated the relative predictive power of vocabulary depth and reading fluency on the reading comprehension of advanced Korean EFL learners in college. By doing so, the scope of paradigmatic relations, as part of vocabulary depth, was extended to encompass associative vocabulary as well as synonyms and antonyms, and reading fluency at the discourse level was considered. For this study, 139 college students were tested on a range of vocabulary depth tests, as well as reading comprehension and text-level reading fluency. The findings revealed that although both vocabulary depth and reading fluency are significant contributors to reading comprehension abilities, the predictability of vocabulary depth was larger than that of reading fluency. In addition, associative vocabulary not only revealed additional predictive power for reading comprehension on top of reading fluency, synonyms and antonyms, but also showed stronger predictability compared to synonyms and antonyms. These results highlight that both vocabulary depth, especially the knowledge of how words are related together, and text-level reading fluency play a crucial role in boosting the reading comprehension abilities of even advanced L2 readers.

Numerous studies have supported the simple view of reading by showing the significant predictive roles of oral language comprehension ability and decoding skills in the reading comprehension of monolinguals and second language learners. However, little is known about its applicability to young foreign language learners who do not have much access to the target language and literacy input outside the school and especially those whose first and second languages are typologically different. This study was designed to examine the contribution of English oral language comprehension ability and decoding skills to the reading comprehension of fifth-grade Korean EFL learners. In doing so, the indirect effects of oral language ability and phonological awareness were also considered, and English reading fluency and Korean reading comprehension abilities were controlled for. The findings not only support the simple view of reading but also highlight the indirect effects of oral language comprehension ability and phonological awareness on reading comprehension abilities via the effects of decoding skills.

In argumentative writing, writers are expected to use hedged expressions and stance devices through specific linguistic expressions to convince their proposition effectively. Yet little research attention has been paid to whether the inclusion of such devices is related to the overall quality of second or foreign language learners’ argumentative writing. In this study, hedges and stance devices that are included in 28 advanced Korean EFL writers’ argumentative writing were analyzed to identify their potential relation to the overall writing quality. Analyses demonstrated that although hedges and stance devices were related to argumentative writing quality in general, the specific linguistic forms that predicted two different aspects of writing quality – formal and content quality – were different. Specifically, hedges played a significant positive role in only content quality of writing, and the specific stance devices that significantly predicted formal quality did not contribute to the content quality, and vice versa. The findings from this study provides important pedagogical implications for EFL writing instruction.

As research evidence for the facilitative effects of reading strategies on reading comprehension has been accumulating, research and pedagogical interests in prereading strategies such as prediction and schema activation are increasing. Yet, little research evidence of how actual performance on such tasks may be related to reading comprehension is sparse. This study explores whether prediction abilities and content schema are related to Korean middle school EFL learners’ reading comprehension abilities in English, and whether such potential relations may differ for factual and inferential comprehension. The study participants were one hundred thirty-seven Korean seventh grade students, and their performance on schema activation, prediction, and reading comprehension abilities was investigated, while controlling for their overall language proficiency and literacy skills. The findings indicated that although both prediction abilities and content schema facilitated reading comprehension, prediction abilities were a relatively stronger predictor of both factual and inferential comprehension. The results further suggest the need to provide effective trainings on pre-reading strategies.

Despite extensive research attention that has been paid to second language (SL) or foreign language (FL) learners’ argumentative writing, most research has focused on the structural features characteristic of such writers. There have not been many systematic attempts to identify the quality of argument features SL or FL writers rely on, and how they contribute to the overall writing qualities. This study was designed to examine the relationship between the Toulmin elements, widely used measures of content qualities in arguments which include claims, data, warrants, rebuttals, qualifiers, and backings, and the overall qualities of advanced Korean high school EFL learners’ argumentative writing. Each of the thirty three participants’ argumentative writing was analyzed, applying the Toulmin model, and the results demonstrate that their overall argument qualities were closely related to the uses of the fundamental Toulmin elements, especially data and predicted best by the degree to which each claim was supported with relevant and sufficient data. These findings shed light on the need for instruction on the use of Toulmin elements in enhancing the overall quality of Korean EFL learners’ argumentative writing.

This study aimed to examine whether overall English proficiency influences the relative predictive power of reading fluency and listening comprehension abilities in explaining the reading comprehension of Korean EFL learners within the simple view of reading framework, when the age factor is controlled for. One hundred sixteen eleventh-grade Korean high school students consisting of two highly distinct groups in general English proficiency―55 Most Highly Capable Students (MHCS) and 61 Capable Students (CS)―were tested on measures of reading fluency, vocabulary knowledge, listening comprehension, and reading comprehension. The findings indicated that reading fluency and listening comprehension abilities were significantly related to the reading comprehension of both MHCS and CS groups. However, the results from a series of hierarchical regression analyses revealed that while listening comprehension was a stronger predictor of reading comprehension of the MHCS group, it was reading fluency that explained more variance in comprehension of the CS group. Implications for reading instructions are discussed.

Despite the general understanding of the prominent role of basic reading sub-skills, such as decoding abilities and reading fluency, in the reading comprehension of younger and proficient first and second language readers, little is known about the role of these skills in older and less skilled readers in foreign language contexts. The present study was designed to investigate how decoding skills and reading fluency relate to the reading comprehension of such readers, and to identify the relative strengths between the two. Two hundred twenty two Korean high school students participated, and their performance on decoding, reading fluency, and reading comprehension tasks was analyzed. The results showed that both decoding skills and reading fluency were strongly correlated to reading comprehension. Moreover, between the two fundamental reading sub-skills, decoding skills outperformed reading fluency in explaining reading comprehension, making a unique contribution beyond the effects of reading fluency. These findings suggest that a basic skill like word decoding still deserves instructional attention even at the secondary schools in EFL contexts.

This study examined whether vocabulary knowledge has meaningful effects on reading comprehension of Korean high school EFL learners and investigated which specific type of vocabulary knowledge, between vocabulary breadth and depth, plays a bigger role in reading comprehension when the learners’ English language proficiency is taken into account. The participants of this study were ninety eight high school EFL learners in Seoul, Korea, and they were tested on a series of measures tapping on their reading comprehension abilities and vocabulary knowledge in two different dimensions (vocabulary breadth and depth). Their listening comprehension abilities were also measured in order to control for the effects of general oral language comprehension abilities known to be the foremost contributor to reading comprehension and thus to enable focused analysis of the role of vocabulary knowledge. The study findings revealed that 1) vocabulary knowledge itself played a critical role in predicting reading comprehension abilities even after controlling for their listening comprehension abilities and that 2) compared to vocabulary breadth, vocabulary depth played a relatively more important role in predicting reading comprehension, regardless of the learners’ language proficiency. The findings provide important implications for vocabulary and reading comprehension instructions for Korean EFL students.

This study investigated whether the simple view of reading framework is supported among Upper elementary Korean EFL learners. Specifically, the relative contributive power of two emergent literacy factors, word decoding and linguistic comprehension abilities, which have been identified as the main determinants of successful reading comprehension, was examined. Ninety nine fifth grade students in Korean elementary school participated in this research, and their decoding skills, listening comprehension abilities, and reading comprehension in English were measured. The findings revealed that both English decoding skills and linguistic comprehension ability were significant predictors of their English reading comprehension, which supports the simple view of reading within the Korean EFL context. Specifically, decoding skill explained more of the variance, compared to linguistic comprehension, in reading comprehension when controlling for each other. The result is discussed in terms of the overall development of L2 proficiency and the role of L2 exposure in L2 reading comprehension development.
