KEMAMPUAN BERPIKIR KREATIF MAHASISWA DALAM MENGEMBANGKAN MEDIA PEMBELAJARAN MATEMATIKA SAAT PANDEMI COVID-19
Full text linkThis study aims to describe students' creative thinking skills in developing mathematics learning media. The research method used is descriptive qualitative method. The subjects of this study were 27 students majoring in mathematics education at a state university in Malang. The collection technique is a project-based group assignment in developing instructional media and the analysis technique uses the indicators used by following the indicators of creative thinking skills and data collection is the assessment of product results and interviews if needed. The results of the study show that the capability to think actively of students in developing learning media is included in the creative model of modification, namely changing the shape of a product so that it becomes more attractive and more practical (2) students develop mathematics learning media based on the problems found, in order to assist students in understanding the learning material; (3) the level of student creativity in developing learning media is very high despite the covid-19 pandemic
Pengembangan e-modul berbasis etnomatematika menggunakan Flip PDF Corporate pada materi sistem linier dua variabel
Full text linkKonsep pembelajaran yang mengintegrasi budaya dan matematika dikenal dengan etnomatematika. Konsep pembelajaran etnomatematika menjadi lebih optimal apabila diterapkan secara nyata dengan mengajak peserta didik merasakan pengalaman secara langsung terhadap budaya di sekitarnya. Penelitian ini bertujuan untuk mengembangkan produk e-modul berbasis etnomatematika menggunakan Flip PDF Corporate pada materi Sistem Persamaan Linier Dua Variabel (SPLDV) yang valid, praktis, dan efektif. Pengembangan ini dilakukan dengan menggunakan metode penelitian Research and Development (R & D) dan model pengembangan ADDIE. Terdapat lima tahap pengembangan, diantaranya: (a) analisis (analysis), (b) desain (design), (c) pengembangan (development), (d) implementasi (implementation), dan (e) evaluasi (evaluation). Instrumen yang digunakan dalam proses pengolahan data, diantaranya angket dan soal evaluasi. Media ini divalidasi oleh ahli, dinyatakan praktis berdasarkan agket respon peserta didik, dan efektif melalui nilai evaluasi peserta didik. Berdasarkan hasil uji, e-modul ini dinyatakan valid, praktis, dan efektif dengan persentase kevalidan materi adalah 85,16 persen, sedangkan media berada pada persentase 93 persen, persentase kepraktisan e-modul ini adalah 88,85 persen, sementara persentase keefektifan e-moul ini adalah 84 persen
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
