This study investigated the effects of exposure frequency, depth of processing, and activity repetition types on vocabulary learning. In total, 78 South Korean fifth-grade students were divided into four conditions. Students in each condition were asked to read a passage with four of the eight target words (exposure: four times) and the other four words (exposure: once) for three days, and to perform the vocabulary activities assigned to each condition. According to the results, exposure frequency and activity repetition type had significant effects on vocabulary learning. Activity repetition type also had a significant interaction effect with exposure frequency and depth of processing. Notably, presenting a word 12 times (4x3) in reading intervals had a more positive impact on vocabulary learning than presenting it three times (1x3), particularly when different vocabulary activities were repeated. Meanwhile, when the same activity was repeated, an activity with a higher depth of processing was more effective for vocabulary learning.

This study investigated the effects of multisensory memory strategies of pairing visual and aural learning strategies of aural lexical advance organizers (LAO) and read-alouds on 146 Korean high school students learning the meaning and pronunciation of 18 unfamiliar English words. In this quasi-experimental design, the control group learned the words on a single mode of written LAO and silent reading as opposed to two treatment groups of aural LAO and silent reading, and of aural LAO and read-alouds, respectively. The effects were tested three times via pre-, post-(immediately after learning), and delayed (30 days later) tests. The immediate and long-term effects were examined by detecting the differences across the three groups in post- and delayed-tests by one-way ANOVA, and the retention of effects was examined by paired t-tests in each group across the three tests. The results indicated that pairing aural LAO and read-aloud strategies was most effective in learning and retention of both vocabulary meaning and pronunciation.

This study aims to analyze the types of cognitive process required to perform vocabulary learning activities in Middle School English textbooks. For this purpose, 26 middle school English textbooks were examined, including 13 for the first year and another 13 for the second year of middle school. The results indicated that vocabulary learning activities emerged in the phase of reading, and then were categorized into pre-reading vocabulary activities and post-reading ones. Eight types of cognitive process emerged in the pre-reading phase and three types in the post-reading phase. That is, the number of vocabulary activities in pre-reading phase was larger than that in the post-reading phase. In addition, the diversity of vocabulary activities in the pre-reading phase was higher than that in the post-reading phase. Based on these results, this study suggests a new model of vocabulary learning activity in middle school English textbooks. A few implications on how to teach new words in English classrooms are discussed.

This study investigates the claim that task-induced involvement load has an effect on vocabulary learning and examines the effect of task types and word concreteness on intentional vocabulary learning in the Korean EFL context. This study aims at testing whether productive word-focused tasks lead to equally effective vocabulary learning when the total involvement load index is equal but the distribution of index levels of each component (need, search, and evaluation) is different. The three productive word-focused task types are gap-fillig, sentence writing, and gap-filling through word transformation. In addition, in order to investigate the effect of word concreteness on vocabulary learning, two groups of target words were selected based on the level of word concreteness. In sum, the results of this study generally supported involvement load hypothesis (Laufer & Hulstijin, 2001) and test types and proficiency levels proved to be important variables that affect vocabulary learning. Moreover, the findings also indicated that word concreteness was not a major factor in vocabulary learning. The pedagogical implications and further suggestions are discussed.

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.

This study compares the results of a survey of vocabulary learning strategy (VLS) use and perceived helpfulness by Korean university students to the taxonomy of VLS first presented by Schmitt. VLS suggested by previous research by the author and changes in technology since the original taxonomy was compiled were added to Schmitt’s list. The survey was administered online to 135 university students in Korea, primarily of Korean nationality. The results show that reported VLS use is up across the board, and the perceived helpfulness of the majority of VLS is up as well. Technological VLS are widely used for meaning discovery, but used moderately for vocabulary consolidation. Trends in the results are discussed, which suggest that learners rely on a range of VLS rather than a few core VLS. Technological VLS are common among Korean university students, though most still prefer traditional methods. Ramifications for vocabulary teaching and strategy instruction are also discussed, as well as suggestions for further research.

The study investigated how task types such as input or output could affect Korean EFL learners’ vocabulary learning at both short- and long-term periods after treatment. Forty two college students in Korea were randomly assigned to one of the four tasks. Based on Involvement Load Hypothesis, each task induced the same or different involvement loads: Read without glossary (Input), Gap with glossary (Input & Output), Gap without glossary (Input & Output), and Sentence and write (Output). Receptive and productive vocabulary knowledge was measured right after the treatment and a month later. The output-oriented tasks were found to be more effective than the input-oriented tasks regardless of type of vocabulary knowledge. The current study concluded that modalities such as input or output other than task-induced involvement load can contribute to Korean EFL learners’ vocabulary learning. The pedagogical discussion will be made at the conclusion.

This study examines the claim that vocabulary learning and retention are dependent on a task's involvement load (i.e., need, search, evaluation), as proposed by Hulstijn and Laufer (2001a). The study aims at comparing the effects of task types and task involvement load on vocabulary retention for Korean EFL university students. More specifically, this study was designed to test whether differential levels of task involvement loads lead to equally effective results to vocabulary retention when the total involvement index being equal. Three types of productive word-focused tasks (gap-filling using a dictionary, writing original sentences, and gap-filling through word transformation) were used to examine the interplay of involvement index and task types. The result indicated that there were significant main effects of task types, test types, and proficiency levels. The results also indicated that there were significant interaction effects of task types on the retention tests, proficiency levels on the retention tests, and task types×proficiency levels on the retentions. The pedagogical implications and further research directions are discussed.

The present study aimed at investigating the effectiveness of bottom-up (BU) and top-down (TD) approaches on EFL learners’ vocabulary learning, the difference in the effects of the two approaches depending upon their level of vocabulary proficiency, and their perception of the approaches. For this study, 122 college students were divided into two approach groups and to two levels in each group depending upon their level of vocabulary knowledge. They were trained with either of the approaches for one semester. The results were that 1) there was no statistically significant differences between the BU and TD approaches, even though the two approaches were effective to improve the students’ vocabulary knowledge; 2) high-level students failed to show any significant differences between the two approaches in the two tests, whereas low-level students in the BU group performed significantly better than those in the TD group in the production test; and 3) they preferred the BU or TD approach to the traditional method in vocabulary learning, and they listed some advantages and disadvantages of the approaches.

This study was conducted to investigate the effects of the sentence-writing task on English vocabulary learning of Korean high school students. The effectiveness of the sentence-writing task can be explained based on the Involvement Load Hypothesis (Laufer & Hulstijn, 2001); yet, there has been no consistency in the results of the previous studies on this hypothesis. In the present study, the effects of the sentence-writing task on vocabulary learning were re-examined in comparison with the gap-filling task. In addition, considering that there have been no studies addressing the effects of autobiographical elaboration (relating the meaning of a certain word to one’s own experience) on memory, the effects of the autobiographical sentence-writing task were compared to those of the imaginary sentence-writing task. Forty high proficiency and 40 low proficiency learners were randomly assigned either of the sentence-writing or the gap-filling task. The results demonstrated that the sentence-writing task is more effective in vocabulary learning than the gap-filling task, regardless of the learners’ proficiency levels. However, no significant difference was found between the effects of the autobiographical sentence-writing task and the imaginary sentence-writing task. Based on the results, the pedagogical implications were discussed in the conclusion chapter.

The present study compared the effects of isolated and integrated form-focused instruction (FFI) on the learning of vocabulary in reading passages. Their effects were also compared to those of incidental exposure on vocabulary learning. It further investigated whether such effects would differ depending on the types of vocabulary assessments. To this end, 80 college students in reading-oriented classes received either isolated or integrated FFI treatments over four 50-minute sessions. They also took the pretest and posttest designed to measure their vocabulary learning. The vocabulary tests consisted of two assessment types: one without contexts and the other provided with contexts. The results showed that the learners remembered the words instructed through isolated or integrated FFI better than those through incidental exposure while reading. However, no significant differences were observed between the two different types of FFI in learning target vocabulary. Some advantages were found for isolated FFI on the vocabulary test provided without contexts and for integrated FFI on the vocabulary test provided with context. Directions for further studies and pedagogical implications will be discussed.

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.

This study aims to investigate the effects of semantic clustering on Korean secondary school students’ English vocabulary learning. The present study was conducted with 56 secondary school students in South Korea. In order to determine if and how semantic clustering affects second language learners, the participants were divided into two groups: a semantically related (SR) word group and a semantically unrelated (SU) word group. The two comparison groups were taught the same 25 vocabulary items in different clusters (SR vs. SU). In the experiment, vocabulary test scores were gathered and analyzed three times: on a pre-, post-, and delayed-test. In the results, scores from the SU word group significantly outperformed the SR word group on the post-test, but on the delayed-test. Findings suggest that presenting new L2 words in SU sets is more effective than SR sets in the short term with Korean EFL secondary school students.

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.

The present study explored the effects of different task types on the autonomous vocabulary learning of EFL learners. To this end, two types of tasks with similar but slightly different levels of involvement loads were developed: a corpus-based task and a word map task. The participants of the study were 41 EFL students from a university in Seoul, Korea. They were divided into two groups: a corpus group (n=20) and a word map group (n=21). A total of 33 target words were selected and the experiment was administered during a period of five weeks. Major findings from the study were as follows: First, the corpus task proved to be more effective than the word map task in productive vocabulary learning, whereas the two tasks showed similar effectiveness in receptive vocabulary learning. Second, the two tasks varied in the effectiveness of vocabulary learning depending on the learners' vocabulary proficiency levels and the specific domains of vocabulary knowledge (receptive and productive). Lastly, the corpus group responded more positively than the word map group to their task and to the vocabulary learning. The findings indicate that the corpus task has advantages over the word map task and provide ‘residual’ empirical support for Hulstijn and Laufer’s (2001) involvement load hypothesis. Based on the findings, some pedagogical implications were made for the effective teaching and the autonomous learning of vocabulary.

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.

With an effort to verify the involvement load hypothesis, this study investigates the effects of three different vocabulary learning tasks - reading, filling in blanks, and sentence writing - on learners' short and long term memory when they are provided with the theoretically identical level of involvement tasks. It is also to examine whether there are any differences of learning effects between input and output vocabulary learning tasks. The experiments were conducted with 86 Korean middle school students grouped by three different task types. Pre-/post-tests and delayed tests were administered and analyzed. It was found that three vocabulary tasks with theoretically identical levels of involvement do not have the same learning effects: the involvement load hypothesis was not completely proved in the case of Korean students' vocabulary learning. The findings implied that (i) the difference of vocabulary learning tasks should be considered even though they have the same involvement load; (ii) given that EFL students learn new words in a limited amount of time in class, the reading task using a dictionary is found to be very helpful; and (iii) it is important to study target vocabulary repeatedly during class and to expose the vocabulary with different tasks to enhance students' retention of the newly learned vocabulary.
