    Penelitian ini menggunakan metode 4D dengan empat langkah yaitu: 1) Tahap define (pendefinisian), 2) design (perancangan), 3) development (Pengembangan), 4) disseminate (penyebaran). Tempat penelitian adalah SD Negeri Gedong 03 Pagi Jakarta. Subjek uji coba lapangan awal adalah kelompok kecil 5 siswa dan subjek uji coba kelompok besar 30 siswa. Pengumpulan data dilakukan dengan angket validasi ahli media, angket validasi ahli materi dan angket tanggapan siswa. Data hasil penelitian dianalisis dengan teknik analisis kuantitatif dan kualitatif. Hasil pengembangan produk adalah media pembelajaran Puzzle materi sumber daya alam mata pelajaran IPA di kelas V SDN Gedong 03 Pagi Jakarta. Hasil validasi ahli materi mendapat skor rata-rata 100% dengan kategori “sangat layak”. Hasil validasi ahli media mendapat skor rata-rata 90% dengan kategori “sangat layak”. Hasil tanggapan siswa berskala besar berdasarkan uji coba lapangan mendapatkan skor rata-rata 83.31% yang termasuk kategori “sangat layak” dan tanggapan siswa bersakala kecil berdasarkan uji coba lapangan mendapatkan skor rata-rata 86.33% yang termasuk kategori “sangat layak”. Berdasarkan hasil perolehan dapat disimpulkan bahwa media pembelajaran kontesktual pada materi sumber daya alam ini sangat layak digunakan sebagai media pembelajaran pada mata pelajaran IPA

    Development of Snakes and Ladder Media Based on Contextual Learning Containing Pancasila Student Profiles in The Pancasila Education Subject to Improve Students' Learning Interest in Elementary Schools

    Contextual learning connects the learning process with everyday life. However, students’ learning interest remains low, as seen from the methods, media, and learning models used by teachers in the classroom. This study aims to develop a snakes and ladders media based on contextual learning, assess its feasibility, and analyze its effectiveness in increasing students’ learning interest at SDN Gedong 03 Jakarta. This research uses a development method with the 4D model, involving media and design experts, material experts, and students. The results show that media and design experts gave an overall score of 80% (feasible category with revisions), material experts obtained 93% (feasible category), while student respondents gave 85% (large group) and 83% (small group). The effectiveness of the snakes and ladders media scored 70% (effective category), and students’ learning interest reached 82% (very good category). The findings indicate that the contextual learning-based snakes and ladders media with the content of the Pancasila Student Profile can increase students’ learning interest and is effective for classroom use, especially in elementary schools

    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

    Full text link
    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

    Full text link
    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
