The first purpose of this study was to ascertain the gains in vocabulary of three selected groups of graduate students presented material by different methods: audio, visual, and audio-visual. The second purpose of this study was to determine whether these gains were maintained after a lapse of time of four weeks.

Current ESL instructors and theorists agree that university students of ESL have a need for a large passive vocabulary. This research was undertaken to determine the effectiveness of a semantic field approach to passive vocabulary acquisition in comparison to a traditional approach. A quantitative analysis of the short-term and long-range results of each approach is presented. Future research and teaching implications are discussed. The outcome of the experimentation lends tentative support to a semantic field approach.

The purpose of this study was to examine the effects of four instructional methods - context clues, definition, elaboration technique, or word parts and word families- on the vocabulary growth and acquisition of adults enrolled in a community college developmental reading course. The study investigated whether performance in any or all of the four instructional methods was moderated by age or language. Seventy-three respondents participated in the study. Participants were enrolled in one of five sections of College Reading Preparatory II (REA0002) offered in the Spring of 2009 at Indian River State College in Fort Pierce, Florida. All five sections of REA0002 were taught by the same professor, a tenured faculty member, chair of the developmental reading department and Associate Professor of Developmental Reading at Indian River State College. The instruction and tests in all five sections of REA0002 were consistent with the research design which insured continuity and consistency in the use of the four instructional methods. All participants received the same treatment and quizzes. During the course of the study, participants first received a pretest, then the treatment or instruction, followed by an instructional quiz, and a delayed post-test was administered at the end of the study. An analysis of the data, which included the pretest, instructional quizzes with four quizzes independently and then combined for an aggregate score for an immediate post-test, and the delayed post-test, yielded mixed results. The four instructional quizzes independently showed definition instruction to have the highest positive impact on student learning. In a measure of gains from pretest to instructional quizzes immediately after treatment, significant improvement in student learning was found only with word parts instruction. / In a measure of performance from pretest to immediate post-test (aggregate score of instructional quizzes) there was a significant gain in students' vocabulary competence, and from pretest to delayed post-test there was a significant decrement in students' vocabulary competence. Age and language moderated vocabulary competence. Further tests of equivalency were mixed and should be interpreted cautiously, as there were a very small number of students in the group of 25 years or older and non-native English speakers. / by Jodi McGeary Robson. / Thesis (Ed.D)--Florida Atlantic University, 2009. / Includes bibliography. / Electronic reproduction.

The role that vocabulary learning plays in second language acquisition has been receiving increased attention from both teachers and researchers. However, there is still much that is not known about the processes through which new words become functioning components of the mental lexicon. This study used a word association test (WAT) to investigate how new words are initially integrated into the lexicon immediately after being studied for the first time. This initial lexical organization of new words was compared with the existing lexical organization of well-known items. In addition, this study investigated how sentence writing, thought to encourage deeper levels of processing, affected how the new words were initially integrated into the lexicon. The participants in this study were 16 volunteers from an Intensive English Language Program. The participants first completed a vocabulary knowledge scale to assess if they knew the new vocabulary words. Then, the participants spent 20 minutes learning the words--either through writing sentences with the words or through choosing their own method of study. Immediately after the 20 minute learning period, the WAT was administered. The results of the WAT indicated that the new words were being organized into the lexicon through meaning-based connections just as the well-known words were. The majority of the meaning-based lexical organization was based on equivalent meaning connections such as synonymy or superordination. The sentence writing condition correlated with a decrease in meaning-based WAT associations for the new words, which indicated that sentence writing may have affected the lexical integration in unexpected ways. Finally, unanticipated WAT response patterns indicated that other contextual factors may have also influenced the responses.

This study looks at English as a Second Language (ESL) students• use of vocabulary learning strategies and whether use of specific strategies is related to success in vocabulary recall and comprehension tests. The primary part of the study focuses on the hypothesis that phonological practice with new words will aid long-term recall and comprehension of these words. An empirical experiment with an experimental and control group was designed to test this hypothesis. The secondary section of the study discusses how often subjects reported using the vocabulary learning strategies categorized by Rebecca Oxford in Language Learning Strategies: What Every Teacher Should Know. In addition, it researches possible correlations between use of these strategies, and scores on subsequent vocabulary recall and comprehension tests. Finally, this study describes how a representative group of students actually apply specific strategies to their vocabulary learning.

It is the goal of all reading instructors to use techniques that will enhance reading comprehension. This is certainly no less so in the second language classroom. Studies have shown that readers possess schemata for text structure that is activated during the reading process. It has also been shown that a reader's textual schemata may be culturally influenced and that second language students may possess textual schemata that conflicts or interferes with the structure of the text making comprehension more difficult. For this reason, second language learners may benefit from explicit instruction in text structure and content relationships. Semantic mapping is a text organization strategy which may be used to explicate text structure and content relationships with both expository prose and fiction. The purpose of this study was to use semantic mapping to explicate the structure and content of short fiction and to measure the effect, if any, on comprehension. For the purposes of this study, comprehension was defined two ways: (1) recognition comprehension, which is the ability to retain and recall factual detail from text content, and (2) comprehension as evidenced by the use of certain critical thinking skills, i.e., elaboration and supplementation in forming written responses. Two hypotheses were posed: 1. The use of semantic mapping will result in an increase in recognition comprehension by a treatment group of English as a second language readers using a semantic mapping strategy, as compared to a control group using an advance organizer, based on a combination multiple choice and true/ false quiz. 2. The use of semantic mapping will result in greater use of elaboration and supplementation by a treatment group of English as a second language readers using a semantic mapping strategy, as compared to a control group using an advance organizer, based on an analysis of a quiz requiring written responses. In order to determine the results of this study, .t-tests were used to compare the mean scores between groups. In the case of recognition comprehension, the group receiving the treatment, semantic mapping, did score significantly higher than the control group. In the case of comprehension, as evidenced by the use of elaborations and supplementations in written responses, the group which used semantic mapping showed a higher level of use, but the difference was not statistically significant. A Mann-Whitney U test ranked the subjects' scores individually on an ordinal scale and then compared the means between groups. In the case of elaborations the treatment group showed a significantly higher level of use. However, there was no corresponding significant difference in the case of supplementations.

Lots of research has been conducted to investigate how vocabulary acquisition can be enhanced effectively. Some research found that grouping words in different ways, like semantically related sets, unrelated sets, and thematically related sets, could affect the effectiveness of vocabulary acquisition. However, there has been no consensus. Though some previous studies suggested that grouping unrelated words may have positive impact on vocabulary acquisition, it is not practical in classroom contexts. The present study examines the effects of presenting words in semantic sets and thematic sets on vocabulary acquisition, as these two ways of grouping are commonly used in everyday teaching. In the present study, 65 Form One students who studied in a Band one EMI co-educational school were recruited as participants. All of them learnt both semantic sets and thematic sets. After learning each set of vocabulary, they took an immediate post test and a delayed post test. Participants were asked to fill in a questionnaire after all the vocabulary sessions had been completed. Eight students, including four high achievers and four low achievers, were interviewed. Results showed that grouping words in semantic sets and thematic sets do not bring any significant difference to vocabulary acquisition in general, though students learnt the verbs in the thematic sets better than verbs in the semantic sets in this study. Learners generally preferred the thematic grouping to the semantic one. It was found that order of presentation could have an impact on learners’ perceptions. Students’ vocabulary learning strategies, which were rather limited, were also identified in the questionnaires and interviews. The findings suggest that both semantic and thematic groupings should be used when presenting words to students. Teachers should also introduce and guide students to use a wider range of vocabulary learning strategies. / published_or_final_version / Applied English Studies / Master / Master of Arts in Applied Linguistics
