ANALISIS HASIL BELAJAR SISWA PADA MATERI PERBANDINGAN BERDASARKAN RANAH KOGNITIF REVISI TAKSONOMI BLOOM
Full text linkThis research to classify the most comparison and described the results of the study grade VII B students SMP Koperasi Pontianak the academic year 2017/2018, based on cognitive Revised Bloom’s Taxonomy. Research method used is descriptive method with a qualitative approach. The subjects of this research were students of class VII B with high and low ability levels. The instruments in this research were daily test questions and student answer sheets on the subject of comparison and interview guidelines. Based on the results of research, obtained the percentage classifications about 20% for understand (C2) and 80% for apply (C3). Students\u27 mathematics learning outcomes based on cognitive domains Revised Bloom’s Taxonomy is that students are better able to solve problems with an understanding indicator of 60% than the problem with the indicator applying at 19.2%. Students with high ability to achieve indicators understand and apply while students with low abilities do not reach both indicators.
Key Word: learning outcomes, ability level, revised bloom’s taxonomy, compariso
Analysis of Mathematical Representation Ability According to Cognitive style
Full text linkThe aim of this research is to analyze students' mathematical representation abilities in terms of cognitive style in the multivariable calculus course taught in semester 4 of the IKIP PGRI Pontianak Mathematics Education Study Program. This research is a qualitative descriptive research in the form of case study research. Research subjects were selected based on their cognitive style which was measured using the geft instrument. Selected subjects were then asked to work on mathematical representation ability questions and then interviewed according to these questions. Based on the research results, it was found that students who had a field dependent cognitive style in symbolic representation were able to link symbols with mathematical concepts, in graphical representation they were able to create images in the form of requested graphs, while in verbal representation they were less able to convey ideas effectively orally. or written. Meanwhile, students with an independent cognitive style in symbolic representation have been able to link symbols with mathematical concepts, in graphic representation they have been able to create images in the form of requested graphics, and in verbal representation they have been able to convey ideas effectively
PENGEMBANGAN MEDIA PEMBELAJARAN GOOGLE SITES BERBASIS PROBLEM BASED LEARNING TERHADAP KEMAMPUAN KOMUNIKASI MATEMATIS DALAM MATERI STATISTIKA PADA SISWA SMP KELAS VIII
Full text linkABSTRAK
Penelitian ini bertujuan untuk menghasilkan media pembelajaran berupa Google Sites berbasis Problem Based Learning terhadap kemampuan komunikasi matematis dalam materi statistika pada siswa SMP kelas VIII. Jenis penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan ADDIE (Analysis, Design, Development, Implemtation, dan Evaluation). Subjek dalam penelitian ini terdiri atas ahli (validator) dan 27 siswa kelas VIII B SMP Abdi Agape Pontianak.

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
