PENERAPAN MODEL PEMBELAJARAN STUDENT FACILITATOR AND EXPLAINING (SFE) UNTUK MENINGKATKAN KEMAMPUAN PEMAHAMAN MATEMATIS SISWA
Full text linkThe problem behind this research is the low level of students' mathematical understanding abilities. One alternative learning that can be applied to improve students' mathematical understanding abilities is the SFE learning model. The aim to be achieved in this study was to determine the effect of using the SFE learning model on improving students' mathematical understanding abilities. The method used in this study is a quasi-experimental method, with research design Non-Equivalent Control Group Design. The research was conducted at TULUS KARTIKA Middle School Bandung. The population in this study were all eighth grade students of SMP TULUS KARTIKA Bandung. The sample in this study were students of class VIII-A as the experimental class and class VIII-B as the control class. The instruments used are in the form of tests of mathematical understanding to determine students' mathematical understanding. Before testing hypotheses, an analysis of data normality and homogeneity is carried out first, both experimental and control classes. The data analyzed were the data from the test results of students' mathematical understanding abilities namely pretest, posttest and gain index. Based on the analysis of the results of the test of mathematical understanding ability, the conclusion is that the SFE learning model has a positive effect on improving students' mathematical understanding abilities, with medium category
AKTIVITAS MATEMATIKA DALAM PERMAINAN TRADISIONAL GATRIK
Full text linkMathematics is a subject learned from pre-school to college. Nevertheless, many students consider mathematics difficult andboring. In reality mathematics is often found in everyday life. Even in culture even though learning mathematics is tucked away.The culture that is most familiar among students is the traditional game. One of these traditional games is “Gatric”. Playinggatrik means students have learned some activities in mathematics. The purpose of writing this paper is to show the mathematicalactivities that exist in the Gatric game. Gatrik is a traditional game that involves two players or more who use two pieces ofwood / wood that have different lengths. This paper is based on a literature review from some supporting literature. Literatureused as a supporting source is the result of research

This study aimed to analyze the improvement of students’ mathematical reasoning and communication ability, students' self efficacy, as well as the relationships among these abilities. This research is a quasi experimental design with a control group of non-equivalence. The population of this study are entire seventh grade students at one Islamic Junior High School in Bandung with a sample class VII-7 and VII-8 as many as 59 students. To obtain the data in this study, used the instrument in the form of test mathematical reasoning and communication abilities, as well as the scale of self efficacy and observation sheet. Quantitative data were analyzed using t-test and correlation test. The results showed an increase in communication and mathematical reasoning skills students who studied with guided discovery learning is not better than students who studied with scientific learning, self-efficacy of students who studied with guided discovery learning learning better than students who studied with scientific learning. Analysis of the relationship indicates that there is a correlation between the students' mathematical reasoning and communication abilities.

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
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
