This study aims to investigate the relationship between high school students’ use of vocabulary learning strategies and their motivation. Its main concern is with how the relationship varies between three student groups divided according to their vocabulary achievement. A survey was taken by a total of 275 students enrolled in a high school in Gyeonggi province. 232 students were selected to be studied. The students were divided into three groups - advanced, intermediate, and beginner levels - based on their performance in vocabulary tests. Their responses were analyzed through SPSS to produce both basic descriptive and inferential statistics. The results show the three groups differ regarding which strategies both extrinsic and intrinsic motivation had a significant impact on - these were memory and cognitive strategies for the advanced level group; decision, social, memory and metacognitive strategies for the intermediate level group, and none for the beginner level group. The results also show that the three groups differ regarding which strategies only extrinsic or intrinsic motivation had a significant impact on.

With the advent of mobile technology, teaching and learning have been more effective with the help of smartphone education applications. This study investigates the effects of vocabulary learning using the smartphone education applications on Korean elementary school learners’ English vocabulary learning and attitudes. A total of fifty-seven elementary school students in the 5th grade participated in the study and were randomly divided into an experimental and a control group. The results of the study manifested that both the experimental and control group showed an increase in the comprehension and production score from pre- to post-tests. The effects of the long-term vocabulary learning, however, were not found to be statistically significant. The average score in the delayed test for both groups slightly increased, which indicated that the treatment was beneficial for learners’ long-term memory enhancement. In the affective domain, interests and confidence ratings were significant for the upper-level experimental and lower-level control group. The results of the survey questionnaire showed that the vocabulary learning using direct examples and pictures for both groups was helpful to improve learners’ lexical competence.

This study aims to investigate the effect of DDL on English lexico-grammar learning by Korean middle school students with respect to the types of learning approach (deductive vs. inductive DDL), the student’s level of English (low vs. high level), and the complexity of lexico-grammar items (simple vs. complex). A total of five experimental lessons were given to 36 students divided into two groups: one group received the lessons through the deductive DDL approach and the other group through the inductive DDL approach. The study found that both inductive and deductive DDL were effective in the learning of English lexico-grammar by the Korean middle school students. However, deductive DDL was more effective for the high level students, while inductive DDL was more appropriate for low level students. In addition, both deductive and inductive DDL were effective for teaching simple lexico-grammar items, but deductive DDL was more effective for teaching complex ones. Most of the participants showed positive responses about DDL and expressed a view that they were able to learn the meanings as well as the forms of target lexico-grammar items.

The study investigates the effect of different types of visual images, i.e., static images versus dynamic images, on English vocabulary learning. Eighty-four students in the fourth grade of an elementary school participated in this study, and they were divided into two experimental groups and a control group. One of the experimental groups utilized static images, and the other group, videos as dynamic images in vocabulary learning. The control group was provided with the definition or the explanation of each target word in L1. The results of the study manifested that the static image group showed higher scores for the post test than the dynamic image group. The comparison of the pre and post affective tests demonstrated that the static image group showed an improvement in confidence in language learning and the dynamic image group showed positive change in the attitude of all three areas: interest, confidence, and aroused motivation. The analysis of the open-ended questionnaires showed that many participants in the static image group tended to use pictures as retrieval cues to remember vocabulary.

Flipped classroom is a pedagogical approach that inverts the flow of the traditional classroom. Due to recent interest in the effectiveness of the flipped learning, research on flipped learning has become pervasive. The purpose of this study, therefore, is to explore the applicability of flipped learning approach to the teaching of English vocabulary for Korean EFL learners. The participants of the study were 40 Korean high school students in Seoul and they were divided into two groups (flipped classroom and traditional classroom). The major results and findings of the study are as follows: The flipped classroom promoted the vocabulary acquisition of Korean high school students in terms of receptive and productive knowledge, which was shown to have a long-term effect. In addition, the flipped classroom had a positive effect on students’ learning attitudes and self-directed learning. Furthermore, the participants’ perceptions of the flipped classroom were very positive. Thus, the implementation of flipped learning will enable Korean instructors not only to explicitly teach vocabulary but also to encourage self-directed and interactive learning to take place in class. Given the beneficial effects of flipped classroom on the vocabulary learning, there is a need for further investigation of the flipped classroom on various skills of English.

This study investigated the effects of using comic strips and context on the vocabulary learning of Korean high school students. Ninety high school students participated in the study and they were divided into three groups: a control group and two experimental groups using comic strips and using context, respectively. In addition, questionnaires were used to investigate students’ attitudes toward English vocabulary learning. The results of the study revealed that there were statistically significant differences in productive vocabulary retention among three groups in terms of short-term memory. In particular, the experimental groups showed high short-term memory rate compared with the control group, which may mean that the use of comic strips and context in English vocabulary learning is effective in improving learners’ productive vocabulary retention. Also there was a statistically significant difference in productive vocabulary retention among three groups in terms of long-term memory. The experimental groups showed a high long-term memory rate compared with the control group. The results of the questionnaire revealed that the two experimental groups showed more positive attitudes towards English vocabulary learning. This may suggest that teaching vocabulary with comic strips and context could be effective for students in English classes, and it is very helpful to develop various activities using comic strips and context.

This study investigates the effects of working memory capacity (WMC) and the types of vocabulary learning, i.e., explicit vs. implicit, on the acquisition of English multi-word verbs. For this purpose, a total of 60 middle school students, divided into two groups (control and experimental), participated in the study. The participants in the control group were taught multi-word verbs in a traditional and explicit manner, whereas the participants in the experimental group were exposed to multi-word verbs with short passages. The results manifested that both of the instructional styles had positive effects on the learners’ acquisition of multi-word verbs in the short-term. Although there was not a significant interaction between WMC and the overall scores on the immediate post-test, according to the scores on the gap-fill tasks which tested learners’ productive knowledge, there were significant differences between the low-WMC and high-WMC groups. High-WMC students learned more target multi-word verbs than low-WMC students on average. The results also showed that WMC and the two different learning types did not affect the students’ acquisition of multi-word verbs in the long-term. Further, the interaction effect between WMC and learning type in the long-term was not significant.

This study examined how smart device applications affected elementary school students who have learning difficulties in English. Five 6th grade students who needed remedial instruction were selected and given 50 hours of instruction using English vocabulary flash cards in a smartphone application. one hundred vocabulary words were chosen and developed for flash cards for the students to examine their intellectual and emotional changes in English learning. The research results showed that the students' vocabulary improved in listening, reading and speaking. It also revealed that the students gained confidence and interest in English learning, and their anxiety decreased. In addition, the application was easy and convenient for the students to use, especially in recognizing the pronunciation and the meaning of the vocabulary words. This study recommends further development and use of smart device applications for elementary school English instruction.

The purpose of this study is to investigate the effects of two different types of vocabulary activities on Korean EFL learners’ vocabulary learning and perceptions. The participants of the study were 30 Korean middle school students in Seoul, and they were divided into two groups (typography and web-based authoring). The former employed the word meaning and spelling image association technique and the latter used a multimedia vocabulary authoring tool for 42 target words. The major findings of the study are as follows: (1) Both the typography and the web-based vocabulary authoring groups showed significant improvement on the posttest of vocabulary test, which indicated the equal effectiveness of the two vocabulary activities; (2) with respect to different English proficiency levels, the low-level group showed much higher improvement of the mean difference between pre and post tests than the higher group; and (3) the participants’ perceptions turned out to be more positive when they participated in creating English word spelling image than authoring multimedia vocabulary learning materials. The results suggest the beneficial effects of active student involvement in the vocabulary learning process. Pedagogical and practical suggestions are made on the effective teaching of English vocabulary in Korean classroom settings.

This study examined the effects of teaching contextual inference and word association strategies on 5th grade elementary school students' vocabulary knowledge development. A total of 56 students participated in the current study, as divided into either the contextual inference group or the word association group. The vocabulary proficiency levels of the participants were also considered and the students in each group were further divided into either the upper level group or the lower level group. The participants experienced six treatment sessions, and in each session they had to study five vocabulary items using each of the two vocabulary learning strategies. The posttest and delayed posttest results indicated that both strategies were effective for the vocabulary knowledge development of the upper level group as well as the lower level group. Some possible implications for elementary school English classrooms in Korea are discussed.

This study aims at investigating the effects of phonological short-term memory (PSTM), learning styles, and oral repetition on middle school students" learning of English vocabulary. Two groups had different treatments (semantic learning and oral repetition) and vocabulary learning was assessed in spelling, meaning, and production twice, immediately after the learning sessions and two weeks thereafter. The results reveal that oral repetition and the PSTM capacity affected the vocabulary learning significantly, but not learning styles. The students with a higher PSTM capacity learned significantly more words but didn"t remember them better for a longer period than those with a lower PSTM capacity. No clear effects of learning styles were noted, while the PSTM capacity of auditory learners was higher than that of visual learners. The oral repetition group learned significantly more words than those who did only semantic learning, which suggests the usefulness of oral repetition in learning new vocabulary.

The purpose of this study is to investigate the effects of using and authoring web-based vocabulary learning tasks on Korean EFL learners' vocabulary acquisition. The subjects of the study were seventy-seven EFL college students in Korea. They were divided into three groups: a traditional control group, and two experimental groups using and authoring the web-based vocabulary tasks, respectively. The major results of the study were as follows: first, the two experimental groups performed significantly better on the vocabulary recognition and use posttest than the control group did. This result indicates that both the use of the web-based tasks and the participation of students in authoring the web-based tasks are more effective in vocabulary acquisition than the use of traditional vocabulary learning methods. Second, both the experimental groups performed significantly better on the delayed posttest than the control group did. This result provides evidence that using and authoring web-based vocabulary tasks are effective in helping students retain newly acquired words in the long-term memory. Third, the learners' responses of the two experimental groups prove to be positive with respect to the use of the web-based task authoring tools in vocabulary learning. Based on these results, some pedagogical suggestions should be made on the effective use of the web-based task authoring tools in Korean English classroom settings.

This study investigated the relations among Korean phonological processing skills, English vocabulary knowledge, and the learning of new English words in 6th grade children. The children were tested in phonological awareness, phonological short-term memory, and naming speed tasks, as well as English vocabulary and paired-associate learning of Korean-English word pairs. Most tasks were significantly correlated with English vocabulary and paired-associate learning. In regression analyses, phonological awareness, short-term memory, and naming speed significantly predicted English vocabulary; and English vocabulary and naming speed predicted paired-associate learning. These results suggest that Korean phonological awareness, naming speed, and short-term memory are associated with English vocabulary knowledge and learning. These findings support the transfer of phonological processing skills across second languages.

Learning vocabulary is considered basic in second language learning and yet Korean high school students tend to use a limited range of vocabulary learning strategies. The present study attempts to investigate the relationship between Korean high school students' English vocabulary learning strategies (EVLS) and vocabulary proficiency. For the purpose, a survey was conducted to 113 first grade high school students to find out their vocabulary learning strategies and their relationship with vocabulary proficiency. The results show that the participating students favored simple memorization strategies regardless of the proficiency levels though the higher group used more EVLS than the lower group. Among the five EVLS categories, the meaning-determination strategies were most frequently used while the social strategies was least used. The results suggest that students need to be encouraged to use various vocabulary learning strategies to use words in their productive language.
