Identifikasi Kedalaman Berpikir Reflektif Calon Guru Matematika dalam Pemecahan Masalah Matematika melalui Taksonomi Berpikir Reflektif Berdasarkan Gaya Kognitif
Get PDFReflective thinking in solving mathematical problems allows students to carry out a reinterpretation process in which cognitive activity involves analytical and decision-making activities on what has been done before. Thus students can realize and think about what he has done and use these skills in subsequent problem-solving. The purpose of this study was to identify the depth of reflective thinking of prospective teachers in solving mathematical problems in terms of differences in cognitive styles. To identify the depth of reflective thinking in problem-solving, using the taxonomic level of reflective thinking consists of six levels, namely (1) remembering, (2) understanding, (3) applying, (4) analyzing, (5) evaluating and (6) creating. This research is a descriptive study with a qualitative approach involving two prospective mathematics teacher students who have a field-dependent cognitive style (SFD) and an independent field (SFI). The results showed that SFD could only reach at three levels, namely remembering, understanding, and applying. While SFI fulfilled the six characteristics of the taxonomic level of reflective thinking, namely remembering, understanding, applying, analyzing, evaluating, and creating
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

Berdasarkanhasil analisis uji t-tes diperolehnilai tHitung= 15.39 dan tTabel= 3.591, sehingga dapat dituliskan tHitung ≥ tTabelatau 15.39 ≥ 3.591. Dengan demikian, dapat disimpulkan bahwa Ho ditolak dan H1 diterima yangmenggambarkan bahwa penggunaan media edukasi “Hitung Kompak” dapat memberi pengaruh dalammeningkatkan kemampuan berhitung siswapada materi volume kubus dan balok.Kata Kunci:media edukasi, hitung kompak, kemampuan berhitung This study aims to describe the impact of the use of "Compact Counting" educational media on numeracy skills inelementary school students. This study included pre-experimental research involving 36 students as research subjectsconsisting of 18 male students and 18 female students. The research design used was One Group Pretest-Posttest Designinvolving one group of subjects. This research was carried out through the planning, implementation stage (pre test,treatment and post test), analysis and findings. The research instrument used in this study is a test of students oflearning outcomes that describes students' numeracy skills and observation sheets. The results of the research dataobtained are then analyzed using technical descriptive statistical analysis and inferential analysis. The data obtainedin the form of quantitative data from the results of tests of numeracy skills in topic of the volume of cube and rectangleare then analyzed using descriptive analysis and t-test. From the results of the study obtained the average value of thepre test of 58.61 which is included in the medium category. While the average value of the post test obtained is 80which is in the high category. Based on the results of the t-test analysis, it is obtained that the t count = 15.39 and ttable = 3.591, so that it can be written t count ≥ t table or 15.39 ≥ 3.591. Thus, it can be concluded that Ho is rejectedand H1 is accepted which illustrates that the use of educational media "Compact Counting" can have an effect inimproving students' numeracy skills in volume and cube volume topic.Keywords: educational media, compact counting, numeracy skil
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
