INVESTIGASI PERKEMBANGAN BELAJAR SISWA KELAS IV SEKOLAH DASAR DI KABUPATEN NGADA, NTT DALAM OPERASI PENJUMLAHAN DAN PENGURANGAN PECAHAN
No full textMakalah ini dimaksudkan untuk memaparkan pelaksanaan eksperimen pembelajaran operasi penjumlahan dan pengurangan pecahan yang telah dilaksanakan di kelas IV Sekolah Dasar Katolik Bomari Langa, Ngada, Flores NTT, dengan level aktivitas berdasarkan pendekatan Pendidikan Realistik. Hasil penelitian menunjukkan bahwa siswa dapat menggunakan banyak strategi ketika proses pembelajaran dilaksanakan secara bertahap berdasarkan tingkatan pemodelan yang berbeda. Dalam level situasional, siswa dapat menggambarkan masalah kontekstual yang diberikan berdasarkan pengalaman (aktivitas) membagi makanan ringan dan pengalaman menaikkan-menurunkan penumpang Bemo. Dalam level referential siswa dapat memperagakan aktivitas situasional yang telah dilakukan dengan menggunakan untaian manik-manik yang telah digantungkan kartu pecahan. Gambaran dari untaian manik-manik yang telah digantungkan kartu pecahan (model of) merupakan jembatan yang membawa siswa menuju pada level general dimana garis bilangan digunakan digunakan sebagai model for penalaran matematika formal. Pada level formal, dengan dibimbing oleh untaian bilangan pecahan, siswa dapat mengkonstruksi soal cerita sendiri yang berhubungan dengan operasi pecahan dan menyelesaikannya secara formal.
Kata kunci: membagi makanan ringan, menaikan dan menurunkan penumpang bemo, penjumlahan dan pengurangan pecahan, matematika realistik
PEMANFAATAN KONTRIBUSI SISWA SEBAGAI ALAT TRANSISI MENUJU PEMAHAMAN KONSEP OPERASI PECAHAN
Full text linkThe purpose of this study was to describes the use of student’s contribution as a transition tool at each level of learning the fraction operation concept. This study involved fourth grade students of an elementary school in Ngada East Nusa Tenggara. The type of this research is Design Research with three stages, namely: initial design, teaching experiment and retrospective analysis. This research begins conduct a hypothetical learning trajectory (HLT) of fraction operations concept. The HLT has been tested before the actual learning process (ALT). The results of the retrospective analysis obtained an overview of the Actual Learning Trajectory (ALT) show that the use of various student’s contribution at each level of learning can lead to understanding the fraction operation concept
Ethnomathematics: Primary School Mathematics Contents on Lio Traditional House at Waka Village in Ende NTT
Full text linkThis study aims to explore elementary school math concepts in traditional houses in Waka village, Ende, NTT. This research is a qualitative research with an ethnographic approach. The process of collecting data in this study was carried out by interview, observation and documentation. The results showed that the Waka traditional house was related to elementary school mathematics. Mathematical concepts found in traditional houses in Waga Village are dominated by the concepts of primitive geometric elements (such as points, lines, line segments, angles) and flat and space forms
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
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
