Strategies of learning English writing skill by Indonesian senior hgh school students
No full textThe research addresses three research objectives: (1) to identify learning strategies of writing skill used by senior high school students in Indonesia, (2) to measure the extent of use of the strategy categories, and (3) to study the differences in the use of the strategies by successful and less successful learners. The subjects of the study were 766 second year senior high school students in East Java, Indonesia. They were asked to complete a questionnaire of strategies of learning writing skill and a self-assessment. The results of the data analysis using Principal Component Analysis yielded twelve components with an initial eigenvalue greater than 1, explaining a cumulative variance of strategies 57.68%. The component matrix was rotated using Varimax with Keiser Normalisation Method and the resulting factors were then treated as posteriori strategy categories and named self-monitoring, language-focusing, planning, metacognitive affective, cognitive compensation, self-evaluating, social process-focusing, authentic practicing, meaning-focusing, vocabulary developing, metacognitive commencement, and mental processing strategies. All of these strategies were used at the moderate frequency level. Finally, successful learners reported using the strategies more frequently than less successful learners did
A STUDY OF THE VALIDITY AND RELIABILITY OF SELF-ASSESSMENT
Full text linkhis study is to investigate whether self-assessment contains construct- irrelevant variances of gender and age, and whether self-assessment correlates with test scores. The data were collected from seventy-eight newly arrived international students at the English Language Center, Michigan State University, USA. Prior to class commencement, they were asked to self-assess their listening, speaking, and interactive skill. Then, a test of listening was administered; finally, they were assigned to perform task-based conversational activities.The statistical findings imply that, firstly, gender and age do not provide construct irrelevant variances to the validity of self-assessment and, secondly, self-assessment produces reliable scores
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
