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 corpora of 46 and 49 introductions of term papers written at two time points of the first and fourth semester of graduate course. In a further step, the structures of the bundles in different rhetorical moves of RA introductions were analyzed to reveal the developmental patterns in bundle use. The analyses show that the Korean graduate students are in the developmental process of academic writing featured by a shift from clausal style to phrasal style as their academic level advances. The results also suggest that the students have difficulty in appropriate bundle use in specific rhetorical moves even at the later academic level of graduate coursework. The pedagogical implications of L2 students’ developmental order are discussed.

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 (about 8% of each corpus) and relative frequencies of each collocation type were similar between the learner and native corpora in descending order of adjective-noun, verb-noun, noun-noun, adverb-verb, adverb-adjective, and noun-verb combinations. The average and individual acceptability rates of each collocation type were around 70% and the problematic constituents were found both in nodes and collocates. L2 influence on learner difficulties mostly lied in confusions about synonyms, overuse of delexical verbs, and use of correct collocations in wrong contexts. Relying on L1 semantic representations, the learners produced non-habitual combinations, misrepresented the intended meaning, and paraphrased L2 collocations. Pedagogical implications arose for teaching L2 collocations about the importance of considering the immediate context of L2 writing and taking different approaches to different types of collocations.

Although reading is part and parcel for the development of L2 literacy skills, such as in reading and writing, the skill has been practiced more often for grammar instruction and literal translation in EFL contexts. While realizing there is less focus on the development of L2 skills through extensive reading (ER) in EFL university contexts,the purpose of the present study was to explore the outcome of an in-class ER approach in English university classrooms. With 249 students, the study reports on the implementation of a university level ER class and the outcome for L2 development via the measures of L2 reading speed, L2 speed reading comprehension, and L2 lexical writing ability. Results indicated positive outcomes for the development of students’ L2reading ability, productive retrieval of academic words and lexical variety. The outcome of the ER program validates the effort and time expended on such programs when graded readers are utilized at matching student Lexile levels.

본 연구는 요약 교육(Summarizing instruction) 및 연습(Practices)이 초급 수준의 L2 성인 학습자들의 읽기 이해와 쓰기에서의 어휘 사용에 어떠한 영향을 주는지를 연구하였다. 이를 위해 L2 학습에서 요약하기의 중요성 및 쓰기에서의 어휘 사용에 관한 이론을 바탕으로 본 연구의 의미를 살펴보았다. 연구 결과 연구에 참가한 학습자들은 요약 교육과 연습 이후 읽기이해 점수에서 의미 있는 향상을 보여주었고, 어휘쓰기에 있어서도 전체적으로 같은 단어의 반복이나 기초적인 단어(the 1st 1000) 보다는 다양하고 수준 높은, 즉, the 2nd 1000 list, 아카데믹한 단어(AWL), 및 그 이상 수준의 단어(NLW) 사용을 보여주고 있었다. 이러한 요약 교육 및 연습이 읽기 이해에 주는 긍정적 효과는 주제가 다른 읽기자료(reading source texts with different topics)를 바탕으로 한 상향식(bottom-up) 읽기 및 쓰기 유발(writing output-promoting)의 통합적인 요약단계에 있다고 보여 진다. 즉, 주어진 읽기자료를 요약하기 위해서 학습자들은 주요 단어, 구, 혹은 문장 수준의 이해를 하고, 이를 다시 본래의 텍스트보다 짧게 요약하기 위해 문장통합(sentence combination), 바꾸어 쓰기(paraphrasing), 통사적 변형(syntactic transformation), 그리고 만들어 내기(invention) 등의 요약 과정들(summarizing processes)에서 사전 사용 및 교사의 모델링과 피드백을 통하여 다양한 단어표현에 노출되고 경험하여 어휘 지식을 늘릴 수 있었고, 이후 쓰기에서의 어휘 사용에 도움을 준 것으로 보여 진다.
