    The purpose of this study was to determine the mathematical representation ability of educated people in the linear buying system using Palembang culinary context questions. This research uses a type of qualitative research with a descriptive approach. The research subjects were students of class XI IPA SMA, totaling 3 people. The data collection techniques used were written tests and interviews. The questions on the written test are of the type of description questions, which consist of 2 questions using the culinary context of Palembang, where the first question uses the context of lamington cake and the second question uses the context of pempek. Data analysis is done by collecting data, reducing it, presenting it, and drawing conclusions from it. The results of the research were that there were two subjects who were able to change the given problem into the form of a mathematical model so that their mathematical representation skills emerged successfully, and one subject was unable to generate mathematical representation abilities because they had not been able to change the given problem into a mathematical model form

    Analysis of Computational Thinking Skills of Students on Exponential Equation Materials through Learning Videos

    Computational Thinking (CT) is a very important skill for everyone because it is not only for solving problems related to computer science and mathematics, but also for solving various problems in everyday life. The application of computational thinking skills in Indonesia is still constrained which results in low computational thinking skills of students. This study aims to identify the ability of computational thinking in students through learning videos containing problem solving using the stages of computational thinking developed on the material of exponential equations. This study used descriptive qualitative methodology with 34 grade 10 learners in one of the high schools in Palembang as research subjects, focusing on three learners who showed high, medium, and low abilities. The research was conducted in three stages: preparation, implementation, and data analysis. Data were collected through written tests and interviews to measure learners' computational thinking ability. The results were analyzed through three stages, namely: data reduction, data presentation, and conclusion drawing. The results showed that learners showed proficiency in exponential material, especially in terms of pattern recognition and abstraction. However, in decomposition and algorithm skills, learners show a lack of ability in solving problems with a systematic approach and accurate solutions

    Hasil belajar menunjukkan perkembangan siswa dalam hal pengetahuan (ingat, pahami, terapkan, dan seterusnya), sikap (menerima, berpartisipasi, dan lain-lain), serta keterampilan (persepsi, gerakan, dan kreativitas) setelah mengikuti pembelajaran. kenyataan di lapangan menunjukkan bahwa masih banyak siswa yang mengalami kesulitan dalam mempelajari matematika yang membuat hasil belajar mereka rendah. khususnya pada materi-materi yang dianggap abstrak. tujuan penelitian ini untuk meningkatkan hasil belajar peserta didik kelas XI.9 materi fungsi nilai mutlak menggunakan Gimkit. Jenis penelitian ini adalah penelitian tindakan kelas (PTK). Penelitian ini dilaksanakan di SMA Negeri 8 Palembang Tahun Pelajaran 2023/2024. Subjek dalam penelitian ini adalah peserta didik kelas XI.9 sebanyak 34 orang. Dalam penelitian tindakan kelas ini akan dilaksanakan melalui beberapa siklus yaitu siklus I dan siklus II. Berdasarkan hasil penelitian didapat terjadinya peningkatan hasil belajar matematika siswa dengan media pembelajaran menggunakan Gimkit. Hal ini ditunjukkan dengan perolehan nilai hasil belajar matematika pada siklus I yang terdiri dari nilai rata-rata siswa sebesar 78.08 dan persentase ketuntusan sebesar 70.59%. Dan peningkatan nilai hasil belajar matematika siswa diperoleh pada siklus II yaitu nilai rata-rata siswa sebesar 87.06 dan persentase ketuntusan sebesar 100%

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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 text
    We 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
