The purpose of this study is to examine level of individual foreign learners' quantitative knowledge of korean vocabulary through the Foreign Learners' Korean Vocabulary Knowledge Assessment and to propose a vocabulary education plan reflecting the result. This assessment was written in focus of semantic relation to identify category, integrated and analytical knowledge of Korean verbs acquired by foreign learners and as a result, the following educational implications were made. First, the learners' knowledge about the vocabulary combinational relationship was very limited. Second, learners are not interested in vocabulary's synonymous relation and antonymous relations. Lastly, there needs to be a concern about postpositional particle-use education. The results of these kinds of research, observes the learners vocabulary acquisition process to determine Korean textbook and present vocabulary level in appropriate in terms of learners' perspective, and provide an opportunity to check if current professors' method is adequate and valid.

This study investigates the effects of written vocabulary exercises on lexical knowledge. Korean university students learning English as a foreign language were randomly assigned to one of four conditions-Condition 1 (having students match word form with word meaning), Condition 2 (having students fill in the blank provided with a list of words), Condition 3 (having students write sentences with the target words), Condition 4 (having students do three practices with the same vocabulary exercise as the condition 1). Each type of exercises in Condition 1, 2, and 3 was designed to classify a different level of mental processing except Condition 4 with multiple encounters of the target words. Learners' vocabulary knowledge of this study was obtained using a format adopted from the Vocabulary Knowledge Scale (VKS) immediately and two weeks later. The findings indicated that: (1) Condition 4 having students do three matching vocabulary exercises was as effective as the condition 3 (one writing exercise) on the immediate learning of word; (2) although there was no significant difference of the effect of vocabulary exercises between Condition 3 and 4, Condition 4 asking students to do three matching vocabulary exercises was the most effective way of vocabulary retention after two weeks.

The primary goal of the study was to provide some preliminary validity evidence for the Vocabulary Grade Levels Test (Busan Metropolitan City Office of Education, 2009), which is designed to measure the receptive vocabulary knowledge of learners in L2. For the purpose of the current study, 327 participants at the elementary school participated in the study and were asked to take two different vocabulary tests. Namely, a Vocabulary Size Test (Nation, 2001) and a Vocabulary Grade Levels Test. The data were analyzed using correlation in order to discover the relationship between these two types of tests. Following this, the Rasch analysis was conducted to examine the reliability and validity of the measurement in question. The data analysis showed that both grade separation reliability and item separation reliability were high, indicating that the Vocabulary Grade Levels Test well discriminates learners with a wide range of proficiency levels. The findings of the study are discussed, along with further improvements in order to ascertain the validity of this particular vocabulary test.

Recently, corpus assisted vocabulary instruction has been attracting a lot of interest. Most studies have focused on understanding language learners' receptive vocabulary knowledge. Limited attention has been paid to learners' productive competence. To fill this gap, this study attended to learners' productive lexical development in terms of form, meaning and use respectively. This study introduced EFL learners to the corpus-based language pedagogy to learn COVID-19 theme-based vocabulary. To investigate the gains and views of 33 EFL first-year college students, a sentence completion task and a questionnaire were developed. Learners' productive performances in the three lexical knowledge aspects (i.e., form, meaning and use) were particularly targeted. The results revealed that the students achieved significant gains in all aspects regardless of their proficiency level. In particular, the less proficient students achieved greater knowledge retention compared with their highly proficient counterparts. Meanwhile, students showed positive attitudes towards the corpus-based approach to vocabulary learning.

The purpose of this study is to deal with vocabulary in KFL. As a result of this study, learners learned vocabulary on average 43 points through contextual inference and introduction of the class to activate background knowledge. In particular, the implicit method showed the highest learning rate of 52 points, and the thematic method had a 41 point-learning rate. In contrast, the semantic method was the lowest with a 25 point-learning rate. There was no significant difference in the improvement rate of upper vocabulary learners, but in the case of the lower learner, there was significant difference in the improvement rate. The difference was not significant in the post-test relative gain rate of upper learners, but there was significant in lower learners. In the delayed test relative gain rate, the difference was significant in all groups. There was correlation between vocabulary difficulty and score, but there was no correlation with the thematic method. And there was no correlation between vocabulary difficulty, improvement rate and relative gain rate in all three classes. However, content understanding, lexical grade, improvement rate, and relative gain rate showed a significant correlation.

The study examined the effects of explicit derivational morphology instruction (henceforth DMI) on the incidental vocabulary acquisition and reading comprehension of 132 Korean 1st-year high school students who responded to a battery of tests (two vocabulary tests and a reading comprehension test). Multiple statistical tools were used to analyze the data: Analysis of Covariance (ANCOVA), Analysis of Variance (ANOVA), Simple Regression Analysis, Tests of Simple Main Effects, and effect size computation using Cohen's d. The results indicated that (a) DMI enhanced students' ability to infer word meanings in context, (b) DMI promoted high proficiency students' reading comprehension, whereas it impeded intermediate proficiency students' reading comprehension, (c) vocabulary knowledge has a strong positive predictive value for reading comprehension, and (d) the gaps of vocabulary knowledge across proficiency levels were still substantial, despite the observation that DMI promoted students' vocabulary acquisition. These results have a bearing on English as Foreign Language (EFL) reading pedagogy.

본 연구의 목적은 의사소통 중심의 수업에서 동료 및 교사와 위키를 활용하여 상호작용하는 것이 우연적으로 산출적 어휘 지식을 향상시키는데 효과가 있는지를 알아보는 것이다. 대학 1학년 학생 82명이 두 집단으로 구분되어 본 연구에 참여했다. 4-5명이 한 조가 되어 7-10분 길이의 영화를 만드는 프로젝트에서 조원들과 교사는 위키로 상호작용하면서 협동하여 영어 대본을 만들었다. 38명(과정 집단)은 위키로 상호작용하면서 영어 대본을 만드는 과정 중에 수시로 교사의 피드백을 받고 수정하면서 최종본을 만들었다. 반면에 44명(결과 집단)은 조원들이 위키로 협력하여 1차 대본을 작성하고 그 결과물에 대해 교사의 피드백을 1회 받은 후 수정하여 최종본을 만들었다. 참여자들의 사전 어휘 지식을 측정하기 위해 어휘 지식 시험을 시행했고, 실험 처치 후에 산출적 어휘 지식의 습득과 유지를 측정하는 사후 시험을 두 번 보았다. 본 연구에서 나타난 결과는 위키를 활용하여 동료 및 교사와 상호작용할 때 어휘를 계속 사용할 기회가 많았던 것이 산출적 어휘 지식을 향상시키는데 도움이 되었으며, 과정 집단이 결과 집단보다 조금 더 큰 폭으로 점수가 상승되었다는 점이다. 이러한 결과들을 종합하여 교육적인 시사점도 논의되었다.

While noticing that there is insufficient interest in the assessment of EFL learners' vocabulary levels or sizes, the researchers developed two tests identical in form (Forms A and B) to assess the lexical knowledge of Korean university learners at the $1^{st}{\sim}10^{th}$ 1,000 word bands by adapting a pre-established vocabulary levels test (VLT). Of equal concern was to investigate if the VLT was equally a valid and reliable instrument to be used on measuring the lexical knowledge of EFL learners. The participants were 804 university freshmen enrolled in a General Education English Course from four different colleges. The learners were asked to respond to either Form A or B. While scores generally fell towards the lower frequency bands, multiple regression found the Korean College Scholastic Ability Test (CSAT) to be a significant variable for predicting the learners' vocabulary sizes. From a methodological perspective, however, noticeable differences between Forms A and B could be found with item response theory analysis. The findings of the study provide suggestions on how future VLT for testing EFL learners may have to be redesigned.

Listening has been a neglected research area despite the crucial role it plays. The present investigation was aimed at examining how the provision of topical knowledge and learners' listening proficiency level affect learners' listening performance under four different preparatory activity conditions: topical knowledge, vocabulary list, language structure, and no activity. A total of 134 participants, assigned to the four different activity groups, took part in the study. The results revealed that the learners who were provided with topical knowledge before listening performed significantly better than the other learners, followed by the vocabulary list group and language structure group, which might be attributed to the activation of their content schemata. The learners who did not perform any preparatory activities achieved the lowest scores. When it comes to the impact of listening proficiency, it was revealed that learners' proficiency level had a significant influence on learners' listening performance, and there was a significant interaction between the learners' level of listening proficiency and preparatory activity. Providing relevant knowledge was effective for both higher level and lower level learners, whereas teaching vocabulary before listening was effective for higher level learners but was not for lower level ones. Based on the results, some pedagogical implications and suggestions for future research were discussed.
