The Institute for Test Research and Test Development (ITT) has provided complimentary Vocabulary Size Tests (VST) in 15 languages to language learners and their teachers, measuring their own or their learners’ receptive and productive vocabulary sizes. This report examines in detail and on a large empirical basis the validity and reliability of these tests.

abstract: The present research study investigated the effects of 8 versions of a computer-based vocabulary learning program on receptive and productive knowledge levels of college students. The participants were 106 male and 103 female Korean EFL students from Kyungsung University and Kwandong University in Korea. Students who participated in versions of the vocabulary learning program with target-word based sentences as well as definitions tended to perform better on receptive and productive vocabulary assessments than those who participated in versions of the program with definitions of words only. Furthermore, results indicated that the difference in receptive scores from immediately after the program to one week later showed a higher drop-rate than the difference in productive scores. In addition, female learners performed receptively better than male learners in post and one-week delayed tests, but significant gender difference failed to occur for the productivity measure. Overall, these results emphasized the importance of productive vocabulary knowledge for better retention of English vocabulary words. / Dissertation/Thesis / Ph.D. Educational Technology 2013

Magister Artium - MA / Vocabulary knowledge is an indicator of language competence. There is a positive relationship between literacy levels and the medium of instruction. Research has shown that reading comprehension is largely dependent on the reader’s vocabulary knowledge in the language in which the text is written (Kieffer & Lesaux, 2007; Nation, 2001; Sutarsyah, Nation, and Kennedy, 1994). The lack of vocabulary knowledge is normally one of the major challenges for many university students struggling with their academic work, especially those for whom the language of tuition is not a first language. African (and Afrikaans mothertongue) students are unable to access information in their home languages because of the lack of terminology and texts in African languages (Edward and Ngwaru, 2011). There is research in South Africa showing that vocabulary is a challenge for university students, especially at first-year level (Butler & van Dyk, 2004, Manik, 2015: 236, Nkomo & Madiba, 2011). Vocabulary, being such a problem, ultimately affects the academic performance of many students. Although some universities have provided multilingual online glossaries (and other resources) in an effort to accommodate multilingual students struggling with comprehension in the medium of instruction, these modes of delivering glossaries are associated with a few problems. Consulting traditional glossaries/dictionaries disrupts the reading process and affects the flow of ideas. It is also possible that the reader will forget the term in question (or its context) right after consulting the dictionary/glossary, therefore readers have to look-up the same term in the dictionary/glossary several times to ensure that they match it with its definition accurately. In some dictionaries/glossary lists, readers will not find the desired term, or the term they find will not provide an adequate definition – which ends up frustrating the reader. Sometimes the list of definitions for one term that readers find in dictionaries/glossary lists is difficult to comprehend. Instead of providing clarity, the definitions can confuse readers even further. The comprehension of some definitions provided in dictionaries/glossary lists depend on prior understanding of several other terms.

In order to learn a new word, a young child must extricate the correct object from multiple possible items in front of them, make an initial association between the specific word-form and the particular referent, robustly link the new word and referent and integrate the new word into their lexicon. Recent research suggests processes that focus attention on the most novel objects in a complex environment, as well as the child's own developing vocabulary play critical roles in this process. This thesis aims to understand the influence of novelty and prior vocabulary knowledge on referent selection and how the interaction of novelty and knowledge can lead to word learning. A series of empirical studies first probed the use of children's endogenous novelty bias in a referent selection task, and then explored how the use of novelty was related to retention of newly mapped word-referent pairs. A second set of studies explored children's use of vocabulary knowledge in ambiguous learning situations by varying the strength of knowledge for competing items present during novel word learning. Finally, a Hebbian Normalized Recurrent Network model was used to explore the underlying associative process of referent selection and retention in novelty- or knowledge-based word learning tasks. Counter to prior work, results here suggest that novelty can override knowledge and in fact, be a detriment to word learning. Children demonstrate a novelty bias across multiple contexts and tasks, but the dominant use of novelty does not translate to retention and does not appear to implicate the use of the child's lexicon. As novelty diminishes and vocabulary knowledge increases, some children can overcome this bias and demonstrate retention for new word-referent pairs. Moreover, the results also suggest that when disambiguation requires the use of weak prior knowledge, more cognitive processing is necessary. The increases in processing subsequently translate to retention for new word-referent pairs. The empirical and computational results together suggest potential limitations of these findings to word learning and suggest future directions exploring variability in object and word representations during learning.

This study analyses the textbook Veckans ord 5 by Britta Redin and Görel Hydén (2003), which is used as a teaching aid in Swedish as a second language. The aim is to examine the theories of vocabulary learning and the learning strategies revealed in the content and design of the textbook and thereby examine its functionality for Swedish L2 pupils. We use content analysis as a method and apply it to selected chapters in the book connected to vocabulary learning and how pupils are expected to consolidate the words they learn. The analysis also considers whether the exercises deal with the form of words (morphology, orthography, phonology) or their content (syntax, lexical field, synonyms, hyponyms, antonyms).   The result shows that the arrangement of the textbook agrees with some common theories and vocabulary learning strategies such as repeating words, linking them to synonyms and learning words through pictures. Another finding is that the exercises highlight the form of words more than their content and meaning.

Vocabulary learning strategies and word knowledge are two central factors in learning a foreign language. Researchers have acknowledged the vital role of vocabulary in second language acquisition. This particular study is trying to fill a void by looking at high-school aged learners, by looking at beginning learners of German and by looking at the expression of word knowledge and strategy use qualitatively. The research methodology for this study is qualitative and exploratory in nature. The participants of this study are 29 high-school students, who participated in a vocabulary review game and filled out exit slips following the game. Of these students, 13 participated in a follow-up interview in which the prompts from the review game were discussed and analyzed. The study revealed beginning learners of German use a variety of learning strategies. Students preferred semantic context over linguistic and social context. They were also able to describe vocabulary items in the target language German, without major breakdowns in communication. Students tried to avoid the use of the German articles and confused grammatical terminology at times. Overall, students knew high frequency vocabulary and how to use it.

Augmented Reality (AR) can be described as one of possible steps between real world and fully virtual reality. Into this mixed reality we can make an overlay with virtual objects onto the real world typically by capturing camera images in real-time to produce a new layer to the environment with which we can interact. Mobile Augmented Reality (MAR) is a term used when equipment through which we achieve AR is small in size and typically easy to carry e.g. a smartphone or a tablet. The concept of using AR in facilitating learning and improving its quality seems to attract more attention in the academic world in recent years. One of the areas that receive much attention is AR language learning. In this thesis an experiment on a group of 20 people was conducted to answer the question: “Is MAR language learning system a viable solution for language learning?” For the purpose of the experiment an AR Language Learning Tool was designed for Android smartphones. This AR Language Learning Tool facilitated vocabulary learning by displaying 3D objects along with their spelling and providing audio of pronunciation. Participants were divided into an equal control group and test group. The control group learned new vocabulary through classic flashcards while the test group used the previously designed AR Language Learning Tool. The Vocabulary Knowledge Scale questionnaires were provided for both groups right after learning and one week later. By performing statistical analysis with Student’s t-test on gathered data it was discovered that there is a positive improvement in long term recall rate in the AR Language Learning Tool group when compared with the flashcards learning group. No difference was found in short term recall rate between both groups. Participants also provided feedback about their quality of experience and enthusiasm for new learning methods. Their answers were very positive and provided proof that mobile AR is a viable method of learning vocabulary.

The purpose of this study was to examine the effects of explicitly teaching students how to recognize and use context clues in content-area texts through a six-week instructional program. Quantitative analyses were performed to reveal any difference between a control and treatment group. Results indicated that students in the treatment group abilities to determine the meaning of unknown vocabulary words were increased significantly more than students in the control group. Students who received the six weeks of instruction more effectively used context clues to determine the meaning of unknown words than students who did not receive the instruction. Recommendations for further research are discussed.

This study investigates the relationship between vocabulary knowledge and reading comprehension of authentic Arabic texts; in particular, it attempts to investigate the percentage of vocabulary coverage (known words) readers need to ensure reading comprehension of two reading passages from online Arabic news source. Data was collected from twenty-three Arabic as-foreign language (AFL) learners at Brigham Young University, who ranged from Intermediate Low to Intermediate Mid in both productive and receptive skills. Two reading comprehension tests, circling the unknown words in texts and a lexical coverage test for each passage texts were given to the subjects. A linear regression analysis of the data shows that there is a correlation coefficient of 0.7 and 0.6 between the percentage of known words and students'comprehension of the two reading texts. The results indicate that the subjects needed to know approximately 90% of running words to adequately comprehend the first passage and around 86% to comprehend the second passage. Based on the findings, this study suggests that there is a lexical threshold for AFL learners,below which adequate comprehension of authentic texts might not be possible.
