    Perkembangan ilmu pengetahuan dan teknologi memberikan dampak yang signifikan terhadap kemampuan berpikir kritis. Akan tetapi, kemampuan berpikir kritis di Indonesia masih perlu ditingkatkan berdasarkan Programer for International Student Assesement (PISA), tahun 2015 Indonesia menduduki urutan ke 62 dengan skor 397 dengan total peserta 72 negara. Untuk itu diperlukan pembelajaran dikelas dan mampu meningkatkan kemampuan berpikir kritisnya, yang mudah dihapal sintaknya dan sesuai dengan karakteristik keterampilan Abad 21 salah satunya yaitu model pembelajaran RADEC berbantu media audio visual. Tujuan dari penelitian in yaitu untuk mengetahui pengaruh model pembelajaran RADEC berbantu media audio visual terhadap kemampuan berpikir kritis siswa pada materi sistem reproduksi. Penelitian ini dilakukan di MAN 4 Karawang pada tahun ajaran 2023/2024. Sampel yang digunakan dalam penelitian ini berjumlah 53 siswa yang terdiri dari kelas XI IPA 2 sebagai kelas eksperimen (29 siswa) dan kelas XI IPA 1 sebagai kelas kontrol (24 siswa) dengan teknik pengambilan sampel yaitu sampling jenuh. Penelitian ini menggunakan pendekatan kuantitatif dengan metode quasi experimental dengan desain penelitian non-equivalent control group desain. Data penelitian diperoleh dari hasil pretest dan posttest yang didapat dari soal tes berupa uraian sebanyak 12 butir dengan indikator kemampuan berpikir kritis, lembar observasi dan angket respon siswa. Analisis data penelitian meliputi uji normalitas, homogenitas, uji hipotesis, uji N-Gain serta uji effect size. Hasil penelitian menunjukkan nilai rata-rata N-Gain kelas eksperimen sebesar 0,75 berkategori tinggi sedangkan nilai rata-rata N-Gain pada kelas kontrol yaitu sebesar 0,55 termasuk kategori sedang. Hasil analisis data pretest dan posttest menunjukkan terdapat data yang tidak berdistribusi normal sehingga dilanjutkan dengan uji Mann Whitney diperoleh nilai signifikansi 0,000<0,05 yang artinya H0 ditolak dan H1 diterima. Maka dapat disimpulkan bahwa terdapat pengaruh positif model pembelajaran RADEC berbantu media audio visual terhadap kemampuan berpikir kritis siswa pada materi sistem reproduksi

    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

    Tokoh Sakera dalam Perspektif Sejarah Sosial: Representasi Perlawanan Rakyat Kecil

    Get PDF
    Kajian sejarah Indonesia kerap didominasi oleh narasi besar yang berpusat pada tokoh nasional, sementara figur-figur lokal sering terpinggirkan. Salah satu tokoh lokal yang menarik untuk dikaji adalah Sakera, sosok legendaris dari Madura yang dalam tradisi lisan digambarkan sebagai pekerja biasa sekaligus jagoan rakyat yang berani melawan penindasan kolonial maupun praktik ketidakadilan sosial. Penelitian ini bertujuan untuk menjelaskan Sakera dalam perspektif sejarah sosial dengan menempatkannya sebagai representasi perlawanan rakyat kecil terhadap struktur kekuasaan yang menindas. Metode yang digunakan adalah studi literatur dan analisis naratif dengan memanfaatkan sumber-sumber primer berupa cerita rakyat, ditunjang oleh literatur sekunder berupa buku dan artikel-artikel akademik. Hasil kajian menunjukkan bahwa figur Sakera tidak hanya berfungsi sebagai simbol keberanian dan harga diri masyarakat Madura, tetapi juga sebagai media ekspresi resistensi sosial yang memperlihatkan ketegangan antara rakyat kecil dan penguasa. Relevansi tokoh Sakera tetap terasa hingga kini, karena nilai-nilai perjuangan dan keberaniannya dapat menjadi inspirasi dalam menghadapi berbagai bentuk ketidakadilan kontemporer. Dengan demikian, kajian ini menegaskan pentingnya tokoh lokal dalam memperkaya historiografi Indonesia melalui perspektif sejarah sosial

    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

    Get PDF
    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

    Get PDF
    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

    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
