The effects of vocabulary enhancement activities on EFL learners
No full textLink to publisher's homepage at https://jcsi.unimap.edu.my/This study compared the effects of vocabulary enhancement activities on first-year English as a Foreign Language (EFL) learners’ reading comprehension and vocabulary improvement. In the activities, these learners were assigned to study a list of fifty to one hundred words a week. The learners studied word functions and had to find words’ definition and sample sentences from a dictionary by themselves. Both formative and summative tests were conducted to test the learners’ vocabulary knowledge and reading comprehension ability. This study compared the learners’ performance between those who studied fifty and one hundred words a week. The objectives were to investigate (1) whether the learners’ performance was affected by the number of words assigned each week, and (2) how vocabulary enhancement activities affected learners’ reading comprehension skills
and vocabulary knowledge. The findings demonstrated that (1) the learners who studied one hundred words per week did not outperform the students who studied fifty words a week, and (2) this vocabulary enhancement activity did not provide enough support for the learners to acquire vocabulary knowledge. The findings suggested that it was essential for learners to study words in context rather than from a given list of words
Effects of Formative Self-Assessment on Thai Students’ English Language Proficiency
Full text linkThis study aimed to gain more understanding of Thai EFL students’ self-assessment during practice test engagement. The participants were 95 Thai undergraduate students majoring in English at a public university in Thailand. The correlation and multiple regression analyses were employed to study the relationship between the practice test and English language proficiency test (TOEIC) scores. The analysis of the confusion matrix was also performed to measure the accuracy of students’ self-assessment from the practice tests. The findings revealed that while Thai EFL students perceived themselves as “poor performers” for grammar and listening skill, their self-perception for vocabulary improvement was positive. A significant correlation was also found between the vocabulary practice test and the English proficiency test scores. The completion of multiple practice tests enhanced the students’ vocabulary knowledge and enabled them to improve their English proficiency test score. Finally, the confusion matrix results revealed the accuracy for students’ self-perception of grammar and listening skill. They did not overestimate or underestimate their abilities, but accurately predicted themselves as “low achievers” for these two skills. As demonstrated in the findings, students are the key factors for their learning success. It is essential to engage them with their own learning process, so that they will be able to identify their strengths and weaknesses in learning
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
