Pengembangan Video Pembelajaran Animasi Berbasis Problem Based Learning pada Mata Pelajaran Matematika
Get PDFPenggunaan media pembelajaran yang tidak bervariasi mengakibatkan hasil belajar siswa yang kurang. Berdasarkan hasil observasi ditemukan 10 orang siswa nilainya belum mencapai KKM, sehingga dilakukan penelitian menggunakan video pembelajaran animasi berbasis problem based learning. Penelitian ini bertujuan untuk mengetahui rancang bangun media pembelajaran video animasi berbasis problem based learning pada mata pelajaran matematika, dan mengetahui kelayakan nya. Metode pengumpulan data dilakukan dengan observasi, wawancara, dan kuesioner/angket. Teknik analisis data dilakukan dengan analisis deskriptif kualitatif, dan deskriptif kuantitatif. Rancang bangun pengembangan media menggunakan model pengembangan ADDIE meliputi tahapan analyze, design, development, implementation, evaluation. Hasil review ahli isi mata pelajaran diperoleh persentase 95,83%, review ahli desain pembelajaran dengan persentase 97,22%, review ahli media pembelajaran dengan persentase 93,75%, hasil uji perorangan dengan persentase 94,44%, dan hasil uji coba kelompok kecil dengan persentase 93,51%. Berdasarkan hasil uji ahli dan uji siswa maka video animasi yang dikembangkan layak untuk digunakan dalam proses pembelajaran
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
Media Pembelajaran Cerita Bergambar Berbasis Problem Solving Pada Materi Volume Kubus dan Balok Muatan Pelajaran Matematika Kelas V
Get PDFPenelitian pengembangan ini dilatarbelakangi oleh kurangnya penggunaan media pembelajaran yang bervariatif yang menyebabkan pembelajaran menjadi monoton sehingga siswa merasa jenuh dan bosan mengikuti kegiatan pembelajaran Tujuan penelitian ini untuk menciptakan produk berupa media pembelajaran cerita bergambar dan mengetahui kelayakan media tersebut. Penelitian ini pada model pengembangan ADDIE (Analyze, Design, Development, Implementation, Evaluation). Media pembelajaran yang dikembangkan berupa media cerita bergambar berbasis problem solving materi volume kubus dan balok pada muatan pelajaran matematika untuk siswa kelas V SD. Metode pengumpulan data yang digunakan yaitu kuesioner. Data kuesioner yang diperoleh kemudian dianalisis dengan teknik analisis kuantitatif. Hasil penelitian menunjukkan bahwa (1) rancang bangun media cerita bergambar berbasis problem solving sesuai dengan model pengembangan ADDIE, (2) hasil uji kelayakan produk oleh ahli isi pembelajaran sebesar 92,85%, hasil validasi ahli desain pembelajaran sebesar 95%, hasil validasi ahli media pembelajaran sebesar 92,64%, hasil uji coba perorangan sebesar 96,96% dan hasil uji kelompok kecil sebesar 97,47% dengan kualifikasi untuk semua uji yang dilakukan adalah sangat baik. Sehingga dapat disimpulkan bahwa media pembelajaran cerita bergambar berbasis problem solving dinyatakan layak digunakan dalam kegiatan pembelajaran matematika di kelas V SD

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
