  • 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.

  • 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.

  • This study investigated the effects of collocation-based vocabulary instruction for the experimental group (G2). It was compared to the traditional wordlist-based vocabulary instruction for the control group (G1). This results reflect the development of low level high school EFL learners' vocabulary learning strategy use and the positive change in the affective domain. In the analysis of the survey responses, G1 and G2 did not differ significantly on the first questionnaire. They did, however, differ significantly on the second questionnaire. G2 used more strategies to discover and to consolidate the meaning of the words by means of combining words. In terms of the affective domain, G2 participated more actively in the learning activities, which had a significant effect on vocabulary growth, memory, self-confidence, motivation, and cooperative learning. This is attributable to the fact that G2 was more inquisitive, interested, challenged, participatory, cooperative, and attentive than G1 in performing the vocabulary task activities. Moreover, the data collected from the questionnaire showed that G2 performed more interactive and dynamic activities in solving the given tasks.

  • This study examined the language acquisition of children from Chinese families in Korea under the bilingual background of Korean and Chinese, focusing on pronunciation and vocabulary. First, in the analysis of pronunciation acquisition, children correctly realized the lenition, aspirated sound, glottalization, palatalization, nasalization, and liquidization while the realization of pronunciation rules for unfamiliar words was low. There were also errors caused when the application principles of pronunciation were not accurately understood or they were not partially acquired. Second, in the analysis of vocabulary acquisition, the acquisition of receptive vocabulary was in the order of verb, noun, and adjective while they clearly understood vocabulary used in the actual relationships with school, family, and peers. In the acquisition of productive vocabulary, they showed the 'meaning-centered principle' of learning the meaning of vocabulary first and then learning its form afterwards. The amount of study and exposure to Korean language had effects on the improvement of vocabulary. Even though this study focused on the errors and characteristics in the acquisition process of Korean pronunciation and vocabulary for children from Chinese families in Korea, it could not clearly find out which one would have greater effects on the acquisition of Korean language. However, lots of exchanges and experiences with surrounding environment and peer group had great effects on the language acquisition and language acquisition transfer of children.

  • Objective: The goal of this study is to research how mother's literacy interaction influences children's interest in vocabulary and reading. Methods: The research subjects selected were 120 children who were three to four-year-old and their mothers. This study conducted questionnaires about the literacy interaction of the mothers. This study also surveyed vocabulary and interest in reading of the children by directly visiting the institutes and by researching the subjects individually. This study used technical statistics, Person's product-moment correlation analysis, and multiple regression analysis in order to analyze the collected data. Results: The results of this study are summarized and concluded as follows. First, open interaction among the sub-areas of a mother's literacy interaction significantly affected children's vocabulary. Second, a mother's literacy interaction with children had no direct impact on the child's interest in reading. Conclusion/Implications: The mother's literacy interaction could have a correlation with the vocabulary development of three to four-year-old children, and a mother's application of open interaction could significantly influence the receptive vocabulary and expressive vocabulary of children.

  • This study evaluated the content of Korean vocabulary learning applications with a focus on tablet PC applications. We analyzed 51 Korean vocabulary learning applications. The instruments in this study were developed based on Yoo et al. (2012)' Vocabulary Learning Game Application Evaluation Criteria and Hyun et al. (2013)' Educational Application Evaluation Criteria. Data were analyzed using a t-test and one-way analysis of variance. The main results are as follows. First, each criteria's score was fairly good; the ease of use had the highest scores and the amusement had the lowest scores. Second, there was a significant difference in the interaction by vocabulary teaching approach. Applications based on a whole language-teaching method had higher scores than applications based on a phonics instructional teaching method inducing more operation and with immediate feedback. Third, there was significant difference in the sum of score and each criteria of developmental appropriateness, educational values, amusement, function and interaction by type of learning. Applications of combining type had higher scores in every criteria except for ease of use than applications of description type. These findings provide a preliminary evidence that the systematic Korean vocabulary learning application facilitates preschoolers' vocabulary learning.

  • This paper makes a quantitative analysis of the diachronic evolution of ancient Chinese vocabulary by constructing and counting a large-scale rough annotated corpus. The texts from Si Ku Quan Shu (a collection of Chinese ancient books) are automatically segmented to obtain ancient Chinese vocabulary with time information, which is used to the statistics on word frequency, standardized type/token ratio and proportion of monosyllabic words and dissyllabic words. Through data analysis, this study has the following four findings. Firstly, the high-frequency words in ancient Chinese are stable to a certain extent. Secondly, there is no obvious dissyllabic trend in ancient Chinese vocabulary. Moreover, the Northern and Southern Dynasties (420-589 AD) and Yuan Dynasty (1271-1368 AD) are probably the two periods with the most abundant vocabulary in ancient Chinese. Finally, the unique words with high frequency in each dynasty are mainly official titles with real power. These findings break away from qualitative methods used in traditional researches on Chinese language history and instead uses quantitative methods to draw macroscopic conclusions from large-scale corpus.

  • The purpose of this study was to investigate the relationship between parents' behavior during picture-book reading and home literacy environment and their effects on toddlers' vocabulary. The subjects of the study were 46 toddlers and their parents. The MCDI-K(Im, 2002), Lee and Kim(2004)'s categories of Verbal Behaviors, the categories of Nonverbal Behavioral Analysis(Kim, 2005), and the Home Literacy Environment Index(Han, 2006) were used. The analysis of the collected data was guided by the research questions and involved the use of descriptive statistics, t-test and an analysis of relevant correlations. The results of this study were as follows; First, the toddlers' receptive vocabulary score was 1.2 times higher than the toddler's expressive vocabulary score. Second, the father's book reading behaviors and mother's book reading behaviors were quite similar, the most frequent types of behavior being the use of 'feedback', 'explanation', 'questioning' and 'pointing'. On the other hand, there was a significant difference between the reading behavior of the mother and father as regards the categories of 'linguistic attention ventilation', 'suggesting', 'directing(instructing)', 'expanding feedback', 'pointing' and 'gesture'. Mothers performed more of these behaviors than the fathers. Third, toddler's vocabulary scores were positively correlated with the mother's 'linguistic attention ventilation'. However, the mother's use of 'restriction' was negatively correlated with the toddler's vocabulary level. Toddler's vocabulary scores were positively correlated with the father's 'description', 'reasoning/predicting', 'questioning about function or action', 'demanding feedback' and 'pointing'. The toddler's vocabulary scores were also positively correlated with the relative abundance of home environment materials and the amount of time spent on parent-child home literacy activity.
