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 analyzed English words that are used in the middle school English text books of the 6th and the 7th National Curriculum in Korea. For this analysis, an English corpus of a total of 1,230,023 nodes was built out of 63 English textbooks of the 6th and the 7th National Curriculum. The study specifically investigated the following items for analysis: 1) tokens and types of words used in the middle school textbooks, 2) frequency of the words, and the numbers of new words introduced in each school-year, 3) high-frequency words in the textbooks with reference to those in large-scale general English corpora, 4) parts of speech of the words and their frequencies, and 5) the comparison of the words used in reading parts and listening parts. Analysis of the corpus revealed the following results. Regarding the average number of tokens and types, the textbooks based on the 7th Curriculum contain more than those based on the 6th Curriculum. As for the frequency of the repetition of words, the 6th curriculum textbooks are more than the 7th curriculum textbooks.
