    This study aims to examine the effect of using digital technology on improving the understanding of mathematical concepts in secondary school students. The research was conducted at SMAN 1 Terara by involving 30 students of class X and XI as respondents. The method used was a quasi-experiment with a pre-test and post-test design to measure changes in students' understanding before and after the application of digital technology in mathematics learning. The digital technology used in this study includes interactive math applications and learning videos integrated in the learning process. The results showed a significant increase in the mean scores of the pre-test and post-test, with the pre-test score of 65.4 and the post-test score increasing to 82.1. A paired t-test showed that this difference was statistically significant (p < 0.05). This finding indicates that digital technology can significantly improve students' understanding of mathematical concepts. Technology-based learning assists students in understanding difficult mathematical concepts through visualization, interactivity, and self-directed learning. However, the successful implementation of technology is also influenced by teacher readiness and adequate access to technological devices. The conclusion of this study is that the use of digital technology has the potential to improve the quality of mathematics learning in secondary schools. Therefore, it is recommended to further integrate technology in the mathematics curriculum and provide training to teachers to maximize its utilization in learning

    Pengaruh Model Pembelajaran Problem-Based Learning (PBL) Dalam Meningkatkan Kemampuan Pemecahan Masalah Matematika Siswa MTs NW Narmada Ditinjau dari Segi Gender

    Penelitian ini bertujuan untuk (1) memproleh bukti empiris tentang pengaruh model pembelajaran problem-based learning (PBL) dalam meningkatkan kemampuan pemecahan masalah matematika dan (2) memperoleh bukti empiris perbedaan kemampuan pemecahan masalah Matematika setelah diajarkan dengan model pembelajaran problem-based learning (PBL) ditinjau dari segi gender. Penelitian ini menggunakan penelitian eksperimen semu dengan desain pretes dan postes dengan kelompok non-ekuivalen. Penelitian ini menggunakan dua kelompok eksperimen dan dua kelompok kontrol. Populasi penelitian ini terdiri dari seluruh siswa kelas VII MTs NW Narmada dari sekolah putra dan dari sekolah putri. Pengambilan sampel dengan teknik sampling purposive. Dari populasi yang ada diambil empat kelas secara acak yang selanjutnya ditentukan dua kelas eksperimen (satu kelas putra dan satu kelas putri), dan dua kelas kontrol (satu kelas putra dan satu kelas putri) yang dipilih secara acak. Data dikumpulkan menggunakan tes bentuk uraian dan observasi kegiatan siswa. Untuk mengetahui pengaruh model pembelajaran dan perbedaan hasil berdasarkan gender data dianalisis dengan menggunakan ANACOVA (α = 0,05). Hasil penelitian menunjukkan bahwa (1) pembelajaran matematika dengan problem-based learning (PBL) berpengaruh dalam meningkatkan kemampuan pemecahan masalah Matematika dan (2) terdapat perbedaan kemampuan pemecahan masalah Matematika setelah diajar dengan model problem-based learning (PBL) ditinjau dari segi gender yaitu siswa dari kelas putri lebih tinggi tingkat kemampuan dalam memecahkan masalah Matematika dibanding kelas putra

    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
