PENGGUNAAN MODEL PEMBELAJARAN KOOPERATIF TIPE COOPERATIVE INTEGRATED READING AND COMPOSITION UNTUK MENINGKATKAN KEMAMPUAN REPRESENTASI DAN PEMECAHAN MASALAH MATEMATIS SISWA
Full text linkPenelitian ini bertujuan untuk menelaah peningkatan kemampuan representasi dan pemecahan masalah matematis siswa, mengkaji perbedaan peningkatan kemampuan representasi dan pemecahan masalah matematis siswa ditinjau dari KAM, serta sikap siswa terhadap pembelajaran matematika dengan model pembelajaran kooperatif tipe Cooperative Integrated Reading and Composition (CIRC). Penelitian ini merupakan penelitian quasi experiment dengan desain kelompok kontrol non-ekivalen. Populasi pada penelitian ini seluruh siswa kelas VIII SMP Negeri Unggul Sigli dengan sampel siswa kelas VIII-A dan VIII-B sebanyak 58 siswa. Untuk memperoleh data dalam penelitian ini, digunakan instrumen berupa tes KAM, tes kemampuan representasi dan pemecahan masalah matematis, serta skala sikap dan lembar observasi. Analisis data dilakukan secara kuantitatif menggunakan uji-t dan uji Anova dua jalur. Hasil penelitian menunjukkan peningkatan kemampuan representasi dan pemecahan masalah matematis siswa yang memperoleh pembelajaran kooperatif tipe CIRC lebih baik daripada siswa yang memperoleh pembelajaran konvensional, terdapat perbedaan peningkatan kemampuan representasi dan pemecahan masalah matematis siswa yang memperoleh pembelajaran kooperatif tipe CIRC dan siswa yang memperoleh pembelajaran konvensional ditinjau dari kemampuan awal matematis siswa (tinggi, sedang, rendah). Analisis data skala sikap menunjukkan bahwa sebagian besar siswa bersikap positif terhadap pembelajaran matematika dengan pembelajaran kooperatif tipe CIRC.

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

Using of Wingeom Software in Geometry Learning to Improving the of Mathematical Representation Ability
Full text linkThe purpose of this study was to determine the use of Wingeom software in geometry learning in the Department of Mathematics Education. This type of research is quasi-experimental. This study examines the use of Wingeom software in geometry learning in the Department of Mathematics Education. The population in this study were all students of the Department of Mathematics Education under the Faculty Education and Teacher Training, Universitas Malikussaleh, and the samples were students of class A1 and class A2. The study was divided into two learning groups, namely the experimental group with the use of Wingeom Software and the control group with ordinary learning. This study begins with an instrument test which shows that (1) Validity indicates that the results are significant, (2) Very high reliability, (3) Good distinguishing power and (4) Moderate difficulty level. To test of homogeneity and normality that the data is homogeneous and normal. Based on the results of calculations using the t test at the significance level α = 0.05, obtained tcount of 4.59 with a significance value of 0.003 while the table of 1.68. Because tcount> ttable (3.127> 1.68) and significance <0.05 (0.003 <0.05). Then it can be concluded that the increase in the ability of mathematical representation of students who get learning with the use of Wingeom software is better than the ability of mathematical representation of students who get ordinary learning without Wingeom software
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
