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.

Textbook is very important in English learning and teaching. The goals of this paper are (i) to analyze the distributions of modal auxiliaries in middle school and high school English textbooks and (ii) to compare the analysis results with those of the general- purpose English corpora. Our study is based on Corpus Linguistics, and we are using corpus-analysis methods and tools in our research. In our study, we consider English textbooks as corpus texts and we will analyze them with NLPTools, which is a corpus- analyzing program. After we survey the distributions of modal auxiliaries, we will focus on a modal auxiliary can. We will examine not only syntactical distributions of a modal can but also semantic/functional distributions of this modal in English textbooks. In order to analyze the semantical distributions of can, we will use semantic tags and divide its semantic/functional category into three groups: ability, permission, and possibility. We will also divide the syntactic distributions into the nine verb phrase structures. After we closely examine the syntactic and semantic/functional distributions of a modal can, we will compare the analysis results with those of the LLC Corpus, the LOB Corpus, and the British National Corpus. Through the study, we want to show that the actual distributions and usages of a modal can in middle and high school English textbooks are a little different from those in other general-purpose English corpora.

The purpose of this paper is to cross-culturally analyze the meaning of 'love' in Korean and American pop lyrics of 1980's. Pointing out that the information provided by dictionaries is not sufficient to understand the cultural meaning of 'love', the corpus analytic method of semantic prosody is introduced as it is explicated by Hunston (2002). Using this semantic prosody technique, three different sets of pop lyrics are analyzed with WordSmith Tools software. The three data sets, one Korean and two American, represent 150 pop lyrics. Specifically, these texts are analyzed in terms of distribution patterns of 'love' in the lyrics. First, the modification pattern of 'love' is investigated. It is found that the Korean data is significantly skewed toward negative expressions, producing negative semantic prosody of 'love', while the American data which reflect American culture is overwhelmingly skewed toward positive expressions, producing positive semantic prosody. That is, Koreans experience 'love' in a fairly negative terms in their pop music, while Americans basically treat it positively. Interestingly, the American pop lyrics popular with the Korean public show in-between characteristics. Next, the predication patterns of 'love' are investigated when it plays the role of subject NP. The result again shows that these two cultures define 'love' drastically differently in their pop music. In sum, the semantic prosody technique proved to be useful as an analytic method for cross-cultural studies.

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. Comparison of vocabularies used in the text corpus and in general large-scale English corpus shows that there are more similarities than differences.
