Sri Setia Wati, (2019):Pengaruh Pendekatan Realistic Mathematics Education terhadap Kemampuan Komunikasi Matematika pada Mata Pelajaran Matematika Kelas VI Sekolah Dasar Negeri 130 Pekanbaru
Penelitian ini bertujuan untuk mengetahui pengaruh yang signifikan penerapan pendekatan realistic mathematics education terhadap kemampuan komunikasi matematika siswa kelas VI SDN 130 Pekanbaru. Penelitian ini dilatarbelakangi atas rendahnya kemampuan komunikasi matematika siswa. Sebagian siswa kesulitan dalam menyelesaikan soal komunikasi dan belum mampu memberikan penjelasan yang baik setelah memperoleh jawaban dari soal yang diberikan guru. Penelitian ini adalah penelitian Quasi Eksperimen dan desain yang digunakan adalah Pretest-Postest Control Group Design. Populasi penelitian ini siswa kelas VI SDN 130 Pekanbaru, dan sampel penelitian ini adalah sampel jenuh. Dari dua kelas yang ada, kelas VIa sebagai kelas eksperimen dan kelas VIb sebagai kelas kontrol. Pengambilan data dalam penelitian ini menggunakan dokumentasi, lembar observasi dan tes. Berdasarkan hasil penelitian rata-rata skor kemampuan komunikasi matematika siswa pada kelas eksperimen sebesar 82,533 dan kelas kontrol sebesar 74,167. Dari analisis data, maka diperoleh nilai thitung = 3,665, ttabel = 1,672 pada taraf signifikasikan 5%. Maka thitung > ttabel atau 1,672 < 3,665, maka Ha diterima dan Ho ditolak. Maka dapat diambil kesimpulan bahwa ada pengaruh yang signifikan penerapan pendekatan realistic mathematics education terhadap kemampuan komunikasi matematika siswa pada materi sifat- sifat bangun ruang di kelas VI SDN 130 Pekanbaru.

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
TRANSFORMASI KURIKULUM TERHADAP PEMBELAJARAN ABAD 21 DALAM PERSPEKTIF GURU"
Full text linkTransformasi kurikulum dalam konteks pembelajaran abad ke-21 menjadi isu penting dalam upaya peningkatan mutu pendidikan. Penelitian ini bertujuan untuk menganalisis perspektif guru terhadap pelaksanaan transformasi kurikulum dalam mendukung pengembangan keterampilan pembelajaran abad ke-21, yang meliputi berpikir kritis, kreativitas, kolaborasi, dan komunikasi. Penelitian ini menggunakan metode deskriptif kualitatif dengan melibatkan 15 guru sekolah dasar dan menengah dari berbagai latar belakang pendidikan. Data dikumpulkan melalui wawancara, observasi, dan analisis dokumen, kemudian dianalisis menggunakan teknik analisis tematik. Hasil penelitian menunjukkan bahwa sebagian besar guru memandang transformasi kurikulum khususnya melalui penerapan Kurikulum Merdeka sebagai upaya untuk menciptakan pembelajaran yang lebih fleksibel, berpusat pada peserta didik, dan kontekstual. Namun, guru masih menghadapi berbagai tantangan dalam menyesuaikan desain pembelajaran, mengintegrasikan literasi digital, serta menilai keterampilan berpikir tingkat tinggi (HOTS). Kesimpulan dari penelitian ini menunjukkan bahwa transformasi kurikulum berpengaruh positif terhadap penguatan pembelajaran abad ke-21, tetapi keberhasilannya sangat bergantung pada kesiapan guru, pengembangan profesional berkelanjutan, dan dukungan sistem sekolah. Peningkatan kompetensi guru dalam pedagogi digital, inovasi, dan refleksi menjadi faktor kunci dalam mewujudkan transformasi kurikulum yang efektif dan relevan dengan tuntutan abad ke-21.

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
