This study explores the development of English textbooks in North Korea through corpus-based analysis aimed at illuminating the differences between materials produced during the Kim Jong-il and Kim Jong-un regimes. In the context of educational reforms and changing political ideology, this study investigates BNC/COCA-based lexical coverage and the…

In L2 pragmatics, only a few studies have examined task complexity. Furthermore, the existing studies have predominantly focused on the cognitive dimension and have lacked consistent findings. González-Lloret and Ortega (2018) and Pallotti (2019) have thereby contended that socio-interactional features be incorporated into task design. Along this…

This study investigated if the difficulty of instructional classroom English in primary teacher-guidebooks of English is adequately manipulated by learner-proficiency. Corpora of classroom English were compiled from 20 guidebooks from five publishers, approved following the 2015 Revised National Curriculum of Korea. Extracted materials from grades…

The purpose of this study was to investigate the continuity of reading passages of Korean high school English textbooks with the 2015 Revised National Curriculum using CohMetrix, a software that analyzes English texts in a range of linguistic features. Twentyone English textbooks were analyzed: 11 High School English, five High School English I,…

This study explored how task complexity, writing behaviors (i.e., pausing and revision behaviors), and writing performance (i.e., task completion, coherence and cohesion, language use, and expression and tone) influence and relate to each other. Thirty advanced-level Korean EFL undergraduates completed writing tasks differing in complexity. A…

The Cognition Hypothesis postulates that more cognitively complex tasks can trigger more accurate and complex language production, thereby advancing second language (L2) development. However, few studies have directly examined the relationship between task manipulations and L2 development. To address this gap, this article reviews, via an analytic…

We explored whether task complexity, operationalized by the two types of writing prompts, affects EFL high school students' narrative writing in terms of syntactic complexity, lexical complexity, fluency, cohesion, and text quality. 32 intermediate EFL students who were randomly assigned to two prompt groups completed a written narrative task…

This corpus-driven longitudinal study investigates the structural use of lexical bundles in published research article (RA) introductions in applied linguistics written by English experts and Korean graduate students across two different levels of study. Frequency-based bundles were retrieved from a corpus of 200 published RA introductions and two…

Developing small learner and native corpora, this case study examines how Korean L2 learners used six types of lexical collocations in L2 writing to address (a) the frequency and acceptability of learner collocations, (b) problematic constituents of deviant collocations, and (c) possible sources of the learner difficulties. The overall frequency…

This study investigated whether task complexity may affect L2 speaking performance as predicted by the Cognition Hypothesis (Robinson, 2011), and whether the effect of task complexity may interact with individual differences in working memory capacity. A total of twenty Korean advanced-level EFL learners performed two separate picture description…

This study investigates whether a natural order exists for non-native acquisition in the production of English syllable coda obstruents by Korean and Chinese adult native speakers. We recorded L2 English monosyllabic words produced by 66 Chinese and 51 Korean native speakers. The recorded speech was then evaluated by 11 native-speaker listeners of…
