Analisis Kemampuan Dan Keterampilan Pemecahan Masalah Matematis Serta Sikap Siswa Dalam Pembelajaran Berbasis Masalah Melalui Penilaian Autentik Di SMK
Get PDFTujuan dari penelitian yang dilakukan adalah membandingkan kemampuan pemecahan masalah matematis siswa antara siswa menggunakan pembelajaran berbasis masalah dengan pembelajaran langsung. Selain itu, dilakukan pengamatan tentang sikap dan keterampilan pemecahan masalah matematis siswa selama pembelajaran berbasis masalah berlangsung. Metode penelitian yang digunakan adalah mixed method model concurent embeded strategy. Populasi penelitian adalah seluruh siswa SMK di kabupaten Majalengka. Sampel diambil dengan cara sampling purposive lalu secara acak diambil sebanyak dua kelas. Terpilih kelas X TKJ 1 sebagai kelas eksperimen dan X TKJ 2 sebagai kelas kontrol di SMKN 1 Talaga. Teknik pengumpulan data menggunakan tes tertulis bentuk uraian untuk kompetensi pengetahuan, dan lembar observasi untuk kompetensi sikap dan keterampilan. Teknik analisis data yang digunakan adalah uji perbedaan dua rata-rata. Hasil penelitian menunjukkan kemampuan pemecahan masalah matematis siswa dengan pembelajaran berbasis masalah lebih baik daripada pembelajaran langsung. Mutu gain ternormalisasi kedua kelompok termasuk kategori sedang. Siswa bersikap pada kategori baik selama pembelajaran berbasis masalah dengan berperilaku santun, disiplin, percaya diri, bekerja sama dan toleransi. Siswa dapat menerapkan langkah pemecahan masalah menurut Polya dalam memecahkan masalah matematis tetapi siswa mengalami kesulitan dalam merencanakan pemecahan dan memeriksa kembali hasil
Analisis Penggunaan Direct Torque Control Menggunakan Space Vector Modulation Pada Motor Induksi 3 Phasa Dengan Matlab Simulink Di Laboratorium Konversi Energi Elektrik Itu Malang
Get PDFpada saat ini terdapat beberapa metode pengontrolan torsi motor induksi 3 fasa yang sering digunakan, diantaranya direca torque control konvensional dan direct torque control dengan menggunakan space vetor modulation DTC (direct Jorge control merupakan salah satu metode untuk mengontrol torsi motor induksi yang menghasilkan respon torsi motor yang cepat tetapi memiliki kekurangan yaitu memiliki nipple yang tinggi.

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
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
