    AbstractThe purpose of this research was to design and development of constructivist multimedia learning environment to enhance computer skills for computer education learners. Developmental research (Type I) (Richey and Klein, 2007) was employed in this study. Several methods used were document analysis, survey and case study. The procedures were as follows: 1) to examine the principles and theories 2) to synthesize designing framework 3) to design and develop the constructivist multimedia learning environment based on above mentioned designing framework, and 4) to evaluate the efficiency of the constructivist multimedia learning environment to enhance computer skills. The results revealed that: 1) The constructivist multimedia learning environment comprises of 8 components as follows: (1) Problem base (2) Resources (3) Related case (4) Cognitive tools (5) Computer skill lab (6) Collaboration (7) Scaffolding (8) Coaching centre, and 2) The efficiency of the constructivist multimedia learning environment is shown in several aspects as following details: 1) The Experts review 2) The learner's opinions 3) The learner's computer skills: basic skills, intermediate skills, and advanced skills

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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 text
    We 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

    The components and indicators of professional learning community: the guidelines for educational quality improvement

    A professional learning community (PLC) is a group of educational personnel who come together to exchange knowledge, develop, and collaboratively solve problems related to improving instructional practices and school issues. The common goal is to develop students’ competencies. PLCs have the potential to transform the quality of educational results significantly. Consequently, studying the components and indicators of a PLC and conducting confirmatory factor analysis (CFA) of PLC models can help schools understand the key factors and practices that contribute to PLC success. This knowledge can be applied to develop a strong PLC within the school. The study of components and indicators of the PLC is exploratory research. The samples consisted of 1,080 administrators and heads of the subject group from 120 schools under the Secondary Educational Service Area Office, randomized by multi-stage random sampling. The research tool was a 4-level rating scale questionnaire. Research findings indicate that the CFA of PLCs aligns with empirical evidence. All components in the PLC model have significant factor loadings ranging from 0.916 to 0.945 at the 0.01 level (p<0.01). When ranked from highest to lowest, these components are: i) supportive conditions–structures; ii) shared values and vision; iii) collective learning and application; iv) Shared and supportive leadership; v) supportive conditions–relationships; and vi) shared personal practice. All of these are essential components of a PLC and serve as an important mechanism for educational personnel to work together to improve the quality of schools
