Comparing two types of explicit pronunciation instructions on second language accentedness
장주현,이준규 경희대학교 언어정보연구소 2015 언어연구 Vol.32 No.S
This study aims to compare the effect of two types of explicit pronunciation instructions, i.e., explicit prosody (EP) instruction and explicit segmental (ES) instruction, on second language (L2) accentedness. This study used a pretest-treatment-posttest design. Sixty two Korean EFL 5th and 6th graders of comparable English proficiency were randomly assigned into three groups (i.e., EP instruction group, ES instruction group, and Control group). Prior to pronunciation-focused activities, English teachers taught explicit linguistic information to the EP instruction group and the ES instruction group. The control group participated in a meaning-oriented activity in which explicit linguistic instruction was not provided. The instructions lasted for five weeks. The improvement of accentedness by each group was estimated by the performance of a reading task in which participants were asked to read aloud a series of narrative sentences. From the recorded data of the learners, foreign accents and pitch accents were analyzed into the sequential phases: a pretest, an immediate posttest, and a delayed posttest. Repeated measure ANOVA analyses revealed that the EP instruction group yielded a strong improvement of L2 accentedness (i.e., foreign accent and prosodic grouping with accent types: pitch accent, phrase accent, and intonational boundary) while the ES instruction group showed the positive results in relation to L2 accentendess as well.
Piccolo 파서를 기반으로 신속한 XML 파싱을 위한 XMLPull 파서의 설계 및 구현

현재 XML은 HTML의 대체 마크업 언어로써 그 사용이 확대되어 지고, 또한 XML 데이터를 위한 파서 모델과 파서 구현방식에 대한 연구가 진행되고 있다. 그 연구의 결과로 벤치마킹에서 XML의 파싱모델로는 Pull모델이 빠른 파싱 속도를 나타내었고, 파서의 구현 방식에 있어서는 Push 모델 파서인 Piccolo에서 사용한 parser generator tool인 JFlex와 BYacc/J를 사용하는 방법이 기존의 일반적인 구현방법인 수기 방식보다 파싱이 빠른 결과를 내 놓았다. 본 논문에서는 기존의 파서보다 빠른 파싱속도를 나타내기 위하여 위의 두 방법을 이용하여 파싱을 위한 인터페이스를 설계하였으며 이를 이용하여 JXPull 파서를 구현하였다. 또한 이를 증명하기 위하여 기존의 XML 파서들의 벤치마킹 도구인 saxbench 속도 비교 도구를 이용하였으며 이를 통하여 본 논문에서 제안한 JXPull 파서가 기존 파서보다 빠린 파싱 속도를 보이는 것을 입증하였다.

The purpose of this paper is to investigate the relationship between phonological awareness and stress sensitivity in second language (L2) speech production by Korean learners of English. Phonological awareness (i.e., phoneme deletion test and rhyme detection test), stress sensitivity (i.e., stress manipulation), non-word and vocabulary reading tests were rated by two trained linguists (Frederickson et al., 1997; Wood, 1999, 2006). Regressions indicated that stress manipulation was strongly associated with L2 speech production in terms of phoneme deletion and rhyme detection. The measurements of stress sensitivity showed that phonological awareness contributes to L2 speech production. Further research is needed to explore how L2 learner predictors in relation to various types of speech rhythm and temporal parameters contribute to L2 speech production.

There has been notable increase as a result of the English-medium instruction rapidly expanding in response to higher education globalization trends. The questionof whether students can learn topic knowledge when it is taught in a language inwhich they are not proficient is a crucial one in English-medium instruction research. Few studies have looked into the actual learning processes involved, despite the fact that prior research has mostly concentrated on how English-medium instruction affects measurable learning outcomes. The purpose of this study is to find out how much content knowledge is processed during English-medium instruction lectures by students using deep-level methods, i.e., critical thought, detailed information, and structure. Furthermore, the study investigates the potential correlation between the implementation of such strategies and the motivating beliefs and English listening proficiency of students. Using a mixed-methods approach, questionnaire responses and semi-structured interviews from 60 students in Korea were gathered. The results emphasize that students' self efficacy and intrinsic learning goals are more important indicators of their use of deep processing strategies than is their English listening competency. This study also offers lecturers and program designers insightful suggestions for supporting meaningful subject learning in English-medium instruction contexts.

This study aims to examine the effect of implicit and explicit instruction on second language (L2) pronunciation of adult and young learners in relation to accentedness, comprehensibility, and intelligibility. One hundred ten Korean EFL learners read aloud sentences. Two groups (i.e., explicit pronunciation instruction and implicit pronunciation instruction) were instructed L2 speech regarding accentedness, comprehensibility, and intelligibility explicitly and implicitly for five weeks. From the recorded data of all learners' speech, the measurement of accentedness (i.e., pitch accent), comprehensibility (i.e., speech rate), and intelligibility (i.e., stress timing) was analyzed. Result indicated that the significant effect of explicit instruction was shown prominently for adult learners while the effect of implicit instruction was shown prominently for young learners. Lastly, the study discusses the implications of the findings along with suggestions for L2 pronunciation
