Computer Assisted Instruction (CAI) Use Of Physics Learning Research Group (PLRG) Simulator To Increase Concept Mastery
No full textPerkembangan Teknologi Informasi dan Komunikasi (TIK) telah memberikan kontribusi yang signifikan dalam bidang pendidikan. Pembelajaran yang lebih individual dan fleksibel dengan penekanan pada metode instruksi sedang menjadi tren yang berkembang di seluruh dunia. Penelitian ini menekankan pada penggunaan komputer dalam proses belajar mengajar untuk memberikan instruksi dalam situasi kelas. Model Pembelajaran CAI berbantuan Physics Learning Research Group (PLRG) simulator digunakan untuk meningkatkan penguasaan konsep siswa. PLRG simulator menekankan konsep fisika berbasis penyelidikan ilmiah bagi siswa sekolah dasar hingga perguruan tinggi. Populasi yang digunakan adalah siswa kelas X Sekolah Menengah Atas (SMA). Berdasarkan hasil penelitian, disimpulkan bahwa Model Pembelajaran CAI berbantuan Physics Learning Research Group (PLRG) simulator dapat meningkatkan penguasaan konsep siswa. Hal ini ditunjukkan oleh nilai N-gain yang diperoleh oleh siswa pada kelas eksperimen. Peningkatan kemampuan penguasaan konsep siswa rata-rata berada pada kategori sedang.Kata kunci: Model Pembelajaran CAI, PLRG Simulator, dan Penguasaan Konsep The development of information and communication technology has contributed significantly in education. More individual and flexible learning with an emphasis on instruction methods is becoming a growing trend throughout the world. This study emphasizes the use of computers in the teaching and learning process to provide instruction in classroom situations. The CAI learning model used of the Physics Learning Research Group (PLRG) simulator is used to improve the mastery of students' concepts. PLRG simulators emphasize the concept of physics based on scientific inquiry for elementary school to college students. The population used is students of class X High School. Based on the results of the study, it was concluded that the CAI Learning Model use of Physics Learning Research Group (PLRG) simulator could improve the mastery of students' concepts. This is indicated by the N-gain values obtained by the students in the experimental class. The improvement of students' concept mastery ability is on average in the medium category.Keywords: CAI Learning Model, PLRG Simulator, and Concept Master
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
IMPLEMENTASI MODEL PEMBELAJARAN KONSTRUKTIVISME TIPE NOVICK UNTUK MENINGKATKAN PEMAHAMAN KONSEP PEMBIASAN CAHAYA DAN KETERAMPILAN GENERIK SAINS SISWA SMKN
Full text linkPenelitian ini bertujuan untuk melihat apakah penggunaan model pembelajaran konstruktivisme tipe Novick dapat meningkatkan pemahaman konsep pembiasan cahaya dan keterampilan generik sains siswa SMK. Metode yang digunakan adalah metode eksperimen semu dengan desain ”randomized control group pretest-posttest design.” Penelitian dilakukan terhadap siswa kelas XI pada salah satu SMK yang ada di kabupaten Sumedang tahun pelajaran 2011/2012. Berdasarkan hasil penelitian diperoleh rata-rata N-gain pemahaman konsep kelas eksperimen 0,61 dengan kategori sedang dan kelas kontrol 0,37 kategori sedang. Rata-rata N-gain keterampilan generik sains untuk kelas eksperimen 0,49 kategori sedang dan kelas kontrol 0,28 kategori rendah. Berdasarkan hasil pengujian hipotesis diperoleh kesimpulan bahwa peningkatan pemahaman konsep dan keterampilan generik sains siswa yang menggunakan model pembelajaran konstruktivisme tipe Novick secara signifikan lebih tinggi dibandingkan dengan siswa yang memperoleh pembelajaran konvensional.

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
