The study investigates the effects of corpus-based formulaic sequences learning on developing learners’ writing skills and attitudes. For this purpose, fifty-four high school students participated in the study and were divided into two groups. The experimental group learned formulaic sequences with the corpus-based method, while the control group learned the target items through the definition-centered method. The results of the study showed that no significant difference in writing ability was found between corpus-based formulaic sequences learning and traditional formulaic sequences learning. The corpus-based formulaic sequences learning showed a greater effect on improving grammatical accuracy of writing. The traditional formulaic sequences learning was effective in the acquisition of productive knowledge of formulaic sequences. The results of the survey questionnaire showed that the students showed a positive attitude toward corpus-based formulaic sequences learning, which may mean corpus-based learning can play an important role in increasing students’ motivation. These results may suggest that various corpus-based activities for EFL class need to be developed.

This study investigates the use of cohesive devices in the corpus of Korean college students’ compositions. In particular, it attempts to provide a comprehensive analysis of the lexico-grammatical contexts in which cohesive referential devices are employed in argumentative essays. For this purpose, a Korean EFL corpus and a native speaker corpus were analyzed based on Gray’s (2010) coding scheme. The coding scheme included variables such as the place and unit of the antecedent, the grammatical role and place of demonstratives, and their preceding or following structures. The results of the analysis showed that Korean EFL learners and native writers were similar in that they tended to use demonstrative pronouns as a subject and demonstrative determiners as objects/complements. Besides this general tendency, non-prototypical uses of the determiners were observed. The learners’ corpus manifested an overuse of an extended antecedent which could reduce the clarity of meaning. The most frequent verb following demonstrative pronouns was the copula (i.e., be) in both corpora. Finally, the learners tended to use a much smaller number of abstract/shell nouns than their native speaker counterparts.

This study investigated the structural and functional differences between formulaic sequences in College Scholastic Ability Test (CSAT) and SAT reading assessment texts. The results of the RANGE program showed that SAT used more diverse and difficult words compared to CSAT. The frequency analysis revealed that CSAT used more formulaic sequences than the SAT counterpart. This suggests that CSAT used more repeated expressions, whereas SAT used diverse vocabulary items. The structural analysis showed that noun phrases were the most dominant in CSAT, whereas prepositional phrases were pervasive in SAT. The functional analysis showed that both corpora relied heavily on referential expressions. The results indicate that referential bundles are dominantly used in institutional writing (Biber & Barbieri, 2007). In accordance with the previous studies, the results suggest that high frequency formulaic sequences can be different according to the register. In CSAT, connectives and discourse organizers were prevalent. This may be due to the characteristics of question types in CSAT. The results may indicate that formulaic sequences in texts are partly influenced by the characteristics of a register.

This study investigated the effects of using comic strips and context on the vocabulary learning of Korean high school students. Ninety high school students participated in the study and they were divided into three groups: a control group and two experimental groups using comic strips and using context, respectively. In addition, questionnaires were used to investigate students’ attitudes toward English vocabulary learning. The results of the study revealed that there were statistically significant differences in productive vocabulary retention among three groups in terms of short-term memory. In particular, the experimental groups showed high short-term memory rate compared with the control group, which may mean that the use of comic strips and context in English vocabulary learning is effective in improving learners’ productive vocabulary retention. Also there was a statistically significant difference in productive vocabulary retention among three groups in terms of long-term memory. The experimental groups showed a high long-term memory rate compared with the control group. The results of the questionnaire revealed that the two experimental groups showed more positive attitudes towards English vocabulary learning. This may suggest that teaching vocabulary with comic strips and context could be effective for students in English classes, and it is very helpful to develop various activities using comic strips and context.

This study mainly explores the research themes and topics of corpus-based studies published in English Teaching in an attempt to provide future directions and pedagogical implications in this research domain. For the purposes of the study, a total of 42 corpus-based research articles published in English Teaching were reviewed and analyzed in terms of research topics, methodology, and characteristics of the corpora employed in the studies. The thematic and topical analysis of the corpus-based studies showed that much research, i.e., 64%, has focused on the analysis ofvocabulary items. Further, the analysis of the research methods revealed that corpus-based studies published in English Teaching mainly employed quantitative methods to describe frequency and distribution information of the target linguistic items. It also provided the description of the characteristics of the corpora adopted in the corpus-based research. Interestingly, many corpus-based studies published in English Teaching focused on the analysis of the learner corpus data. The paper discusses the future research directions and pedagogical implications for corpus-based studies on TEFL.

This study investigates the effects of working memory capacity (WMC) and the types of vocabulary learning, i.e., explicit vs. implicit, on the acquisition of English multi-word verbs. For this purpose, a total of 60 middle school students, divided into two groups (control and experimental), participated in the study. The participants in the control group were taught multi-word verbs in a traditional and explicit manner, whereas the participants in the experimental group were exposed to multi-word verbs with short passages. The results manifested that both of the instructional styles had positive effects on the learners’ acquisition of multi-word verbs in the short-term. Although there was not a significant interaction between WMC and the overall scores on the immediate post-test, according to the scores on the gap-fill tasks which tested learners’ productive knowledge, there were significant differences between the low-WMC and high-WMC groups. High-WMC students learned more target multi-word verbs than low-WMC students on average. The results also showed that WMC and the two different learning types did not affect the students’ acquisition of multi-word verbs in the long-term. Further, the interaction effect between WMC and learning type in the long-term was not significant.

This study investigates the effects of collocation task types on Korean high school students' collocation learning and learning attitudes. A total of 118 Korean high school students participated in the experiment, and they were divided into four groups: control group, receptive treatment group, productive treatment group and combination treatment group. In order to investigate the effects of collocation task types on students' English proficiency, each group of students was classified into a high proficiency group and a low proficiency group. The students took a pre-test before the experiment and a post-test after the experiment. After the post-test, the post-questionnaire survey was conducted to examine the students' learning attitudes. The results of the study were as follows: (1) The three types of collocation tasks were effective in learning receptive and productive collocations; (2) in the delayed retention test, it was revealed that the effect of the three types of collocation tasks on both receptive and productive collocation learning lasted; and (3) the result of post-questionnaire survey showed that learning collocation through collocation tasks had positive influence on most students in terms of raising their interest and increasing their self-confidence.

The present study conducted a comparative analysis of use of evaluative adjectives in the essays of Korean EFL learners and native speakers of English. It discussed the characteristics of different types of evaluative adjectives, e.g., frequency, semantic categories, and collocational value of evaluative adjectives. The result of the frequency analysis demonstrates Korean EFL learners’ significant overuse of the limited types of the target items. The analysis of evaluative adjectives by semantic categories shows the similar tendency. For example, the repeated use of a small number of assessment adjectives resulted in the high frequency of adjectives in the assessment category. The present study also demonstrates the collocational associations between the selected evaluative adjectives and intensifiers in the corpus. The descriptive results of the analysis of collocational information indicate that learners employed a less formal/spoken style in the written corpus. As Blagoeva (2004) noted, the differences between the Korean EFL learners and native speakers of English in the characteristics of evaluative expressions might not directly obstruct communication but it is an indication that there is still much to be done in the development of second/foreign language skills.

Vocabulary expansion is essential for learners to gain proficiency in L2, but learners’ lexical knowledge has not drawn much research attention in SLA (Howarth, 1996). In an attempt to throw light on a neglected aspect of learners’ competence, this paper investigates the use of a lexical item in the writing corpora. In particular, it compares the frequency and distribution of intensifiers in the EFL corpus with those in a native English corpus. The result of the frequency analysis in the EFL corpus offers an evidence of significant overuse of the limited types of maximizers and boosters, which in turn result in the inflated frequency of intensifiers. Further, the present study uses the mutual information score to measure the strength of the bond between selected intensifiers and adjacent lexical items. The result does not clearly demonstrate associations between the intensifier and the adjacent words due to the small corpus size, but it provides some possible pedagogical implications for L2 teaching. The frequency information rather than the information on the strength of associations between intensifiers and adjacent words, for example, would be more helpful to EFL learners.
