corpus

In spite of the highly beneficial applications of corpus linguistics in language pedagogy, it has not found its way into mainstream EFL. The major reasons seem to be the teachers’ lack of training and the unavailability of resources, especially computers in language classes. Phrasal verbs have been shown to be a problematic area of learning English as a foreign language due to their semantic opacity and structural differences between English and learners’ first languages. To examine the pedagogic potentiality of the use of corpus linguistics in the context of EFL, the present study aimed at comparing the effect of paper-based data-driven learning (DDL) activities, as a substitute for online DDL activities, with the activities designed based on dictionary entries in terms of their effect on learning phrasal verbs in both short and long run. To this end, the study adopted a quasi-experimental pretest posttest control group design. The analysis of the data collected through an immediate posttest as well as a delayed posttest showed that the DDL activities led to greater improvements by the participants. Based on the results of the study, it is argued that paper-based DDL activities can be used effectively in EFL classes to enhance learning and help learners to become more autonomous in their learning efforts.

Nagy (1988) states that vocabulary is a prerequisite factor in comprehension. Drawing upon a reductionist approach and having in mind the prospects for material development, this study aimed at creating an English for Academic Purposes Word List (EAPWL). The corpus of this study was compiled from a corpus containing 6479 pages of texts, 2,081,678 million tokens (running words) and 63825 types (individual words), and 2615 word families from online resources. The created EAPWL included 636 word families, which accounted for 12%of the tokens in the EAPWL under study. The high word frequency and the wide text coverage of this word list confirm that this word list plays an important role in English for Academic Purpose texts and hence can be a justified resource for material development in the field. From these findings, it can be concluded that the EAPWL created in this study can serve as a guide for material developers and syllabus designers especially in designing course-books, in addition learning these words by learners can help them in better understanding of their texts, and development in their writing and reading comprehension.

There has been increasing interest in utilizing corpora in linguistic research and pedagogy in recent years. Rhetorical organization of different sections of research articles may appear similar in various disciplines, but close examination may show subtle differences nonetheless. One of the features that has been at the center of attention especially in recent years is the idiomaticity of a discourse which can be examined from the perspective of multi-word units captured by the automatic retrieval of lexical bundles. This study takes a corpus-based approach for the identification of lexical bundles. A corpus of 801,894 words from 790 articles was collected. In order to fulfill the purposes of the present study, ABBYY FineReader 10 professional edition, Total Assistant, Antconc 3.2.3, and WordSmith Tools 5 were used to identify lexical bundles. Then these bundles were classified structurally and functionally based on the presented taxonomies in the literature. The results of the current study indicated that the writers of medical research articles mostly rely on text-oriented bundles in the discussion section of research articles to establish academic discourse.

Researchers stated that learning and applying certain set of lexical bundles of native lecturers by non-native lecturers would help students improve their proficiency through incidental vocabulary input. The present study shed light on the lexical bundles in hard science lectures used by Native and Non-native lecturers in international universities with the main purpose of analyzing the structural and functional similarities and differences in their usage. The secondary purpose was to finalize and present a list of explored lexical bundles employed by Native lecturers in these lectures which could be helpful for students and also Non-Native lecturers. The corpus of this study consists of five and a half hours of three different native university lecturers’ lectures and about five and a half hours of three different non-native university lecturers’ lectures who were teaching hard science (nuclear physics and electronic engineering). The data were analyzed using n-gram tool in lextutor.ca website which is a free online software to analyze the lexical bundles of more than two corpora and compare them. Functional and structural analysis gave the following results. Findings showed that lexical richness of both Native and Non-Native lecturers was not good enough to expose students to rich environments to help them improve their English proficiency. In light of structural classification, the results revealed that dependent clause fragments in addition to verb structure phrases were the most widespread and Noun phrase + of-phrase fragments were the least employed structures of the identified lexical bundles in the lectures of Non-Native and Native lecturers. In terms of structural analysis, it was concluded that stance bundles were the most frequent function bundles used by both groups. Therefore, there were both similarities and differences in the structural and functional classifications of lexical bundles in the lectures of native and non-native lecturers.

The study of lexical bundles, known as fixed phrases, chunks, clusters and multi-word expressions, has attracted considerable attention. While there has been much research on lexical bundles across different registers and a number of disciplines, their deployment in some special sections of research articles as the most high-stakes genre has not yet been well explored. Accordingly, the present study aimed at identifying 4-word lexical bundles by analyzing the data obtained from a collection of the abstract and conclusion sections of 1000 English research articles written by L1-persian and L1-English writers in AL and IT , as published between 2015 and 2019. The researchers used Antconc software to analyze the data composed of about 600,000 words; then, the functional analysis was carried out based on Hyland's (2008) framework. Overall, the analysis revealed that AL writers outweighed their IT counterparts in their use of lexical bundles. Also, L1-persian writers used more lexical bundles in the abstract section; despite this, both writers used the same number of bundles in the conclusion section. In addition, both AL and IT writers had a similar use of the three main functional categories; however, there were substantial differences and similarities in regard to these two parts of research articles. The findings of this study can help writing instructors to improve students' academic writing. They can enhance their abilities to better comprehend the role of lexical bundles in different genres and sub-genres.

This small-scale corpus-based study delineates the most common and significant dialectal variations between the two most commonly spoken English varieties: American English (AmE) and British English (BrE). As a result of the corpus analysis, four main areas have emerged as to where dialectal variations take place: pronunciation, vocabulary, grammar, and orthography/punctuation. A total of 26 variations ( f =10 in pronunciation, f =5 in vocabulary, f =6 grammar, and f =5 in orthography/punctuation) was identified by analyzing a variety of sources, including books, articles, online dictionaries, and websites. The significance of the variations in the abovementioned language areas and their implications for language teaching were discussed empirically and pedagogically. Notwithstanding the limitations, the research is expected to contribute to our understanding and awareness of the dialectal variations and assist language learners and teachers with the learning and teaching of these variations pedagogically and systematically since it might serve as a guide or a framework of reference.
