Productive vocabulary

This study investigated the role of interactive output tasks in developing EFL learners’ vocabulary knowledge. The participants were 103 elementary female Iranian EFL learners who were randomly divided into three groups: input-only, input-output-no-interaction, and input-output-interaction. After all participants took a placement test and a vocabulary pretest, the input-only group was exposed to input tasks, while the other two groups received both input and output tasks with or without interaction. Then, all the participants took a vocabulary posttest. The results of ANOVA and Kruskal-Wallis tests showed that the participants in both the input-output-no-interaction group and the input-output-interaction group outperformed the ones in the input-only group in the vocabulary posttest (in both the overall vocabulary test and in the productive vocabulary section). Moreover, the results of the t-test and the Mann-Whitney test revealed that the participants in the interaction and no-interaction groups performed similarly on both the overall vocabulary posttest and the productive vocabulary section. The findings of this study support the idea that output is a facilitative factor for the acquisition of L2 vocabulary and, specifically, productive vocabulary development. The results also suggest that both interactive and non-interactive output-plus-input tasks can lead to higher achievement in vocabulary knowledge compared to the input-only condition lacking output tasks

In this study an attempt has been made to investigate if vocabulary tests may predict L2 learners’ writing score in IELTS. 131 postgraduate international students studying in Universiti Teknologi Malaysia (UTM) who obtained the minimum score (i.e. 6) in IELTS as a requirement for enrollment were participants of this study. Two vocabulary size tests (PVLT & Lex30) together with a test of vocabulary depth (WAT) were given to participants. Then, participants’ scores from three tests were correlated with their score in the writing section of IELTS. The results of the study revealed significant correlation coefficients between productive vocabulary size and academic writing skills. Moreover, the findings of Multiple Regression indicated that productive vocabulary levels test (PVLT) could be possibly a good predictor for IELTS academic writing. Further, scatter plots revealed a possible threshold of 2000 words for a L2 learner to get 7 in IELTS academic writing. The findings drawn from the study enable teachers to predict their learners’ competency in writing skill by through various vocabulary tests.

Learning vocabulary seems to be a major focus of language instruction. The role of vocabulary knowledge in language learning has been studied by many researchers. The present study was conducted to investigate the effect of using online Quizlet flashcards and student-created Quizlet flashcards on learning and retention of receptive and productive vocabulary knowledge. Sixty Iranian elementary high school students who were randomly divided into 3 groups (twenty subjects per group) participated in this study. The materials and data collection instruments included the Quick Placement Test (QPT), the students’ textbook, Top Notch1 from which the vocabulary items were selected, a pre-test, an immediate post-test, and a delayed post-test. It should be mentioned that the control group was taught the words through the conventional method while the first experimental group received the words using online flashcards and the next experimental group worked on developing their own Quizlet flashcards. The results showed that in terms of receptive vocabulary knowledge learning, the students of the online Quizlet flashcards group significantly outperformed students of the control group and online Quizlet flashcards. In learning of the productive vocabulary knowledge, the learners of the control group performed significantly better than other two experimental groups. The results on vocabulary retention revealed that students of the student-created Quizlet flashcards group significantly outperformed students of the control group in terms of retention of the receptive vocabulary knowledge, and in terms of the productive vocabulary knowledge retention there were no significant difference between the groups of the study. These findings will be advantageous for English language teachers to choose the teaching techniques which can facilitate the process of language teaching and learning.
