한국 대학생들의 영어학습 동기 저하 : 성별, 영어 성취 수준, 영어 포기 시기에 따른 양상

유경아 중앙대학교 다빈치미래교양연구소 2023 교양학연구 Vol.- No.24

본 연구는 지방 사립대학교에서 교양 영어를 수강하고 있는 대학생을 대상으로 영어학습 동기 저하 요인의 영향을 살펴보았으며, 이 요인들이 학습자들의 성별, 영어성취 수준, 영어 포기 시기에 따라 차이가 있는지 분석하였다. 동기 저하 요인으로 영어 태도나, 영어 능력과 같은 내적 요인, 교사, 중・고등 교과과정, 환경요인, 사교육 요인과 같은 외적 요인이 포함되었다. 이 연구에서는 영어 태도 요인보다 영어 능력 관련 평균이 더 높아 학습자들의 영어 기초 실력 부족 등이 동기 저하로 이어짐을 알 수 있었다. 외적 요인으로는 중・고등 교과과정요인과 교사 관련 요인이 환경요인보다 동기 저하에 좀 더 영향을 미치는 것으로 볼 수 있겠다. 또한, 대학생들의 영어학습 동기 감소 요인이 성별과 영어 성취 수준, 영어 포기 시기에 따라 유의미한 통계적 차이가 있는지 알아본 결과 성별에 따른 동기 저하의 차이는 없었으며, 영어 성취 수준에 따라 영어 태도 영역에서만 유의미한 차이가 있었다. 한편, 영어 포기 시기에 따라 영어 동기 저하 평균 점수에서 차이가 나는지 알아본 결과 영어 태도, 영어 능력, 교사와 교과과정 요인에서 유의미한 차이가 있었다. 즉, 영어학습에 대한 포기가 빠르고 오래 지속될수록 영어에 대한 흥미가 없으며, 스스로 기초실력이 없다고 인지하며, 교사와 교과과정에 대한 부정적 의견이 많다는 것을 통계적으로 유의미하게 보여주고 있다. 이를 통해 학생들의 동기 상태를 점검하고 동기 향상을 위한 방안을 탐색하도록 한다.

유경아 사단법인 인문사회과학기술융합학회 2019 예술인문사회융합멀티미디어논문지 Vol.9 No.10

Since the evaluation of the language performance tests is done by human raters, there is a lot of concern on scoring consistency, and whether the scores given by raters are reliable. The purpose of this study was to estimate the inter-rater reliability of the English Speaking Proficiency Test(ESPT) from the perspective of the generalizability theory. More specifically, this study attempted to identify major sources of measurement error and the magnitude of each through the estimated variance components. The three English-speaking native teachers participated in this study as raters; two experienced raters and one novice rater. They scored 116 Korean adults' English speaking responses. Their ratings were analysed through the GENOVA program. The results of the GENOVA analyses illustrated that the greatest portion of the total variance was from persons variance and a moderate effect of the tasks on the test scores due to the task difficulty. However, the variance for rater facet was extremely small. One of the interesting findings was that rater’s rating pair influenced the variance. There was a moderate interaction effect between persons and the raters when the raters consisted of one experienced and the other novice as a pair. It indicated that the rater pair containing experienced raters tended to give scores consistently more than the rater pair composing of one experienced and one novice raters.

A Cross-Cultural Study of Korean EFL Learners and Native English Speakers in Refusal Strategy Use

유경아 조선대학교 인문학연구원 2014 인문학연구 Vol.0 No.47

A considerable amount of study on the speech act of refusals has paid attention to similarities and differences of strategy use employed by native and nonnative English speakers. However, a few studies have touched on pragmatic transfer from Korean to English refusals. This study attempted to examine if there are any similarities and differences in the ways which Korean EFL learners, native speakers of Korean and native speakers of English perform the speech act of refusals. This paper also investigated whether there is any evidence of pragmatic transfer used by Korean speakers from L1 in their use of L2. To do this, 40 subjects participated in this study; 10 native speakers of English (group 1), 10 Korean EFL learners with high English language proficiency (group 2), 10 with low English language proficiency (group 3) and 10 native speakers of Korean (group 4). All subjects were asked to fill out a Discourse Completion Test. The results showed that group 1, the native English-speaking speakers, utilized semantic formulas the most, and group 3 used refusal strategies the least. The findings demonstrated several similarities in their refusal strategy use. All four groups employed indirect strategies to refusals more than direct and adjuncts strategies. Reason was the most frequently used semantic formula among the four groups. The results also showed that socio-pragmatic factors such as social status were closely related to the participants' refusal use. All Korean groups tended to offer reasons more frequently to the high status person than the other two statuses. Additionally, the findings of this study revealed evidence of pragmatic transfer from L1 occurred in refusal responses of EFL Korean groups. Theoretical and pedagogical implications are discussed.

몬순기후로 인한 수리수문학적 변화가 팔당호 동물플랑크톤 군집에 미치는 영향

The zooplankton community of Lake Paldang, Korea, was investigated on a weekly basis from 2004 to 2006. The seasonal succession of zooplankton community structure was influenced by hydrological factors such as rainfall pattern and efflux in Lake Paldang. According to the monsoon climate, spring, fall and winter had reduced precipitation, so that zooplankton dynamics of the lake showed a typical succession pattern. In spring, small sized and faster growing rotifera rapidly increased, and copepods and cladocera noticeably increased thereafter. Rotifera dominated the zooplankton community, occupying more than 90% of total zooplankton abundance. Among rotifera, Keratella cochlearis was extremely dominant in spring. Copepoda were mainly present as Copepodid and Nauplius. Among cladoceran species, Bosmina longirostris was dominant. In summer, during the rainy season, zooplankton were flushed out by an associated dam. After the rainy season, rotifera increased rapidly when the water column of the lake was stable. During the fall, zooplankton abundance gradually reduced in accordance with decreasing water temperature. However, the occupation rate of copepod (Copepodid, Nauplius) increased relatively. Zooplankton dynamics were influenced by meteorological changes and hydraulic-hydrological factors, because Lake Paldang is a completely closed ecosystem.

The effect of raters’ language background on English-speaking test ratings across test-takers’ oral proficiency levels

유경아 한국응용언어학회 2010 응용 언어학 Vol.26 No.4

This study examined whether or not raters’ language background influences Korean test-takers’ English-speaking evaluations. Five native and fourteen nonnative English-speaking raters scored 120 speaking samples divided into six different speaking levels in terms of accuracy, vocabulary, fluency and pronunciation. The MANOVA results showed that there were significant effects for raters’ language background on the ratings. Overall, the nonnative English-speaking raters were more severe in their judgments than the native English-speaking raters. There were significant mean differences in accuracy and vocabulary ratings between the two groups of raters across most test-takers’ speaking levels. However, there were no significant mean differences in ratings for higher levels of test-takers for some individual criteria such as fluency and pronunciation. This paper provided some evidence of the effect of language background on English-speaking ratings, indicating that there were some differences between the ratings produced by native and nonnative raters depending on test-takers’ oral proficiency levels and scoring criteria.

유경아,변명섭,윤석제,황순진,류덕희 한국하천호수학회(구 한국육수학회) 2013 생태와 환경 Vol.46 No.1

Blue-green algae blooms occurred during early winter in the North-Han River, Korea. Among blue-green algae, Anabaena spiroides were observed for approximately 33 consecutive days, between 28 November and 30 December, 2011. A. spiroides emerged from Lake Uiam to Lake Paldang, depending on the flow of the river has spread downstream. Changes of physical water environment like rising water temperature and increasing hydraulic retention time influenced the A. spiroides bloom. The A. spiroides bloom showed a very rapid increase in cell density, and a slow decrease: the cell density increased to a maximum of 11,325 cells mL-1 in Lake Paldang (st. 5), and was completely disappeared after the water temperature dropped below 4˚C. A decrease in water temperature was the most influential factor among all environmental parameters, for the reduction of A. spiroides cell density. The A. spiroides bloom was accompanied with the occurrence of very high concentrations of the odor metabolite geosmin. Geosmin reached the peak value of 1,640 ng L-1 in Lake Paldang (st. 4). The geosmin concentration was very strongly correlated with cell numbers of A. spiroides.

The purpose of this study was to investigate the effects of the ethical climates in the relationship between procedural justice, organizational citizenship behavior and service performance in foodservice industry through a multilevel analysis. Data were collected by two levels, 402-individuals and 35-restaurants. The analysis of HLM indicated that at the individual-level, procedural justice was positively related to organizational citizenship behavior. Procedural justice was also found to correlate positively with service performance. At the organizational levels, the ethical climates were positively related to organizational citizenship behavior and service performance. Moreover, the climates of ethical climates were proved to be as a moderator in the relationship between the procedural justice, organizational citizenship behavior and service performance in foodservice industry. Also, the results contribute to the ethical climate literature by appling a multilevel perspective.

A Case Study of the Use of an In-house Oral Exam in a University English Program

유경아 언어과학회 2013 언어과학연구 Vol.0 No.65

Evaluating nonnative English-speakers' English speaking ability has steadily been emphasized over the past two decades in the undergraduate English programs at Korean universities. However, there is insufficient information about how classroom-based oral exams are conducted at college level. In this study, an in-house English oral exam was used to measure students' English speaking abilities. This study examined if the evaluations of an in-house oral exam differ among teachers, and whether the oral exam measures the level of achievement of students' English speaking abilities adequately. Additionally, this study investigated how the students perceived the classroom-based oral exam. The data used included both pre-and post- test results of oral exams and survey questionnaires collected from the students. The results showed that there was no significant mean difference among teachers, which indicates teachers scored with consistency, and the students made statistically significant progress in their speaking abilities. However, the results revealed that the students did not fully master the target course objectives. Based on the findings, theoretical and practical implications are discussed.
