UPAYA PENINGKATAN HASIL BELAJAR MATEMATIKA SISWA PADA POKOK BAHASAN OPERASI HITUNG BILANGAN BULAT DENGAN PENDEKATAN CONTEXTUAL TEACHING LEARNING DI KELAS V SDN GUMURUH 6 BANDUNG TAHUN AJARAN 2010-2011
Full text linkJudul penelitian ini adalah Upaya Peningkatan Hasil Belajar Matematika Siswa Pada Pokok Bahasan Operasi Hitung Bilangan Bulat dengan Pendekatan Contextual Teaching Learning (CTL) di Kelas V SDN Gumuruh 6 Kecamatan Batununggal Kota Bandung (Rina Anggraeni, 0810182). Penelitian ini utamanya dilatar belakangi oleh temuan di lapangan yang menunjukkan rendahnya hasil belajar siswa kelas V SDN Gumuruh 6 dalam proses pembelajaran Matematika.
Rumusan masalah dari penelitian ini adalah bagaimana hasil belajar Matematika siswa dengan pendekatan CTL, kedua bagaimana respon siswa setelah memperoleh pembelajaran matematika dengan pendekatan CTL.
Tujuan dari penelitian ini intinya adalah untuk Meningkatkan hasil belajar siswa kelas V dalam pembelajaran matematika dengan pendekatan CTL dan mengidentifikasi proses pembelajaran matematika dengan pendekatan CTL, dan pengembangannya serta berbagai kendala yang dihadapi oleh guru. Dengan penelitian ini pun diharapkan dapat memberikan manfaat bagi siswa, guru, sekolah, dan pengembangan ilmu pengetahuan.
Penelitian ini dilaksanakan di SDN Gumuruh 6, metode penelitian yang digunakan adalah penelitian tindakan kelas. Prosedur pelaksanaannnya merujuk kepada model Kemmis dan Taggrat. Instrumen dan teknik pengumpulan data yang dikembangkan adalah berupa lembar observasi dan lembar wawancara. Sedangkan untuk validasi datanya peneliti menggunakan bentuk validasi triangulasi.
Setelah dilaksanakan penelitian dari siklus pertama hingga siklus terakhir diperoleh hasil sebagai berikut : pembelajaran Matematika dengan pendekatan CTL dapat meningkatkan partisipasi, minat belajar, dan hasil belajar siswa serta antusiasme guru dalam melaksanakan proses pembelajaran, pendekatan CTL yang dirancang guru juga telah efektif meningkatkan hasil belajar siswa kelas V dalam pembelajaran matematika dan kendala–kendala dalam pembelajaran Matematika dengan pendekatan CTL di Kelas V SDN Gumuruh 6 dapat diatasi.
Adapun untuk selanjutnya peneliti menyarankan agar pembelajaran dengan pendekatan CTL harus lebih dikembangkan dengan memanfaatkan lingkungan yang dekat dengan kehidupan siswa dan optimalisasi penggunaan alat peraga, guru perlu membekali diri dengan berbagai pengetahuan–pengetahuan baru dan terus memotivasi siswa agar lebih semangat dalam belajar, serta pentingnya adanya kerjasama antara pihak sekolah, orang tua dan komite sekolah dalam upaya inovasi pembelajaran di sekolah

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
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
