PENGARUH PEMBELAJARAN PENEMUAN TERBIMBING TERHADAP KEMAMPUAN GENERALISASI MATEMATIK SISWA SEKOLAH MENENGAH PERTAMA
No full textPenelitian ini bertujuan untuk mengetahui apakah siswa pada kelas eksperimen yang belajar geometri dengan pembelajaran penemuan terbimbing memiliki perbedaan kemampuan generalisasi matematik secara signifikan dibandingkan siswa kelas kontrol yang belajar secara konvensional. Sampel terdiri dari tiga kelas, dipilih dari kelas VII secara random klaster. Alat pengumpul data berupa tes bentuk essay dan format observasi. Hasil penelitian menunjukkan: (a) Terdapat perbedaan secara signifikan kemampuan generalisasi matematik siswa kelas eksperimen dibandingkan dengan siswa kelas kontrol. (b) Kemampuan generalisasi matematik siswa pada kelas E2 lebih baik daripada siswa kelas E1. Disimpulkan bahwa belajar geometri dengan pembelajaran penemuan terbimbing merupakan alternatif untuk meningkatkan kemampuan generalisasi matematik siswa
Identifikasi Hambatan Guru Dalam Pembelajaran Matematika Siswa Berkebutuhan Khusus Di SMP Bunda Kandung Jakarta Selatan
No full textAnak berkebutuhan khusus merupakan anak yang dalam proses pertumbuhan atau perkembangannya mengalami kelainan atau penyimpangan (fisik, mental, intelektual, sosial, emosional), sehingga memerlukan perlakuan khusus. Beberapa bentuk hambatan dan penyimpangan perkembangan pada anak berkebutuhan khusus sebagaimana yang sering dikenal dengan tunanetra, tunarungu, tunagrahita, tunadaksa, lamban belajar, berbakat, tunalaras, dan autisme. Artikel ini bertujuan untuk mengetahui hambatan apa saja yang dialami guru dalam pembelajaran siswa berkebutuhan khusus. Pendekatan yang digunakan adalah pendekatan kualitatif. Subjek penelitian meliputi guru kelas VII danVIII. Teknik pengumpulan data yang digunakan adalah wawancara dan observasi. Instrumen penelitian yang digunakan yaitu pedoman wawancara dan pedoman observasi. Berdasarkan hasil penelitian, dapat disimpulkan bahwa hal yang menghambat pembelajaran di kelas inklusi yakni dalam pengelolaan waktu, dan memanipulasi materi pelajaran matematika, karena guru harus memberikan materi yang berbeda agar mudah dan cepat dipahami untuk siswa normal maupun siswa ABK
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Model Pembelajaran Kooperatif Tipe Teams Accelerated Instruction Sebagai Solusi Meningkatkan Hasil Belajar Peserta Didik Pada Materi Teorema Pythagoras
Get PDFMeningkatkan hasil belajar matematika peserta didik SMP Negeri di Kabupaten Bekasi melalui penerapan model pembelajaran kooperatif tipe Teams Accelerated Instruction (TAI) merupakan tujuan penelitian ini. Metode penelitian yang digunakan adalah penelitian tindakan kelas dalam tiga siklus. Subjek yang diteliti 40 peserta didik kelas VIII ketika mempelajari materi teorema pythagoras. Instrumen penelitian yang digunakan lembar observasi, tes bentuk uraian, dan wawancara. Hasil penelitian menemukan pada siklus I, rata-rata aktivitas peserta didik pada seluruh aspek yang diteliti baru mencapai 2,0, pada siklus II meningkat menjadi 2,8 dan pada siklus III menjadi 3,6 dari skor maksimal 4,0. Rata-rata hasil tes pada siklus I yang mencapai KKM baru 35%, pada siklus II meningkat 62,5%, dan pada siklus III menjadi 87,5%. Peningkatan ketuntasan belajar dari siklus I ke siklus II 27,5% dan dari siklus II ke siklus III 25%. Karena indikator keberhasilan penelitian sudah tercapai, maka penelitian dihentikan pada siklus III. Berdasarkan temuan penelitian dapat disimpulkan, upaya meningkatkan hasil belajar matematika siswa pada materi teorema pythagoras melalui model pembelajaran kooperatif tipe TAI berhasil mencapai target penelitian dengan pencapaian ketuntasan pada siklus III sebesar 87,5%.Â
Variations on the Author
Get PDF“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 PDFWe 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 PDFWe 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
