    Penelitian ini bertujuan untuk mengetahui ada tidaknya pengaruh pembelajaran Kooperatif terhadap hasil belajar Matematika siswa kelas XI IPA SMAN 1 Tebing Tinggi. Dalam penelitian ini rumusan masalahnya adalah “Apakah pembelajaran Kooperatif dengan Tipe Student Teams Achievement Division dapat mempengaruhi hasil belajar Matematika siswa kelas XI SMAN 1 Tebing Tinggi Kabupaten Kepulauan Meranti?” Penelitian ini merupakan penelitian eksperimen yaitu penelitian yang bertujuan untuk menyelidiki hubungan sebab akibat dengan cara memberikan perlakuan pada salah satu kelas dan membandingkan hasilnya dengan salah satu kelas yang diberikan perlakuan yang berbeda. Subjek dalam penelitian ini adalah siswa kelas XI IPA2 dan XI IPA3 SMAN 1 Tebing Tinggi dan objek penelitian ini adalah pembelajaran Kooperatif dengan Tipe Student Teams Achievement Division. Pengambilan data dalam penelitian ini mengunakan tes, peneliti memberikan tes yang sama kepada kedua kelas. Tes yang sama bertujuan untuk mengetahui pengaruh perlakuan yang berbeda terhadap hasil belajar siswa. Berdasarkan hasil analisis data, dapat diambil kesimpulan bahwa hasil belajar siswa dengan menerapkan pembelajaran Kooperatif lebih baik dari pada pembelajaran Konvensional. Ini terlihat dari mean ketuntasan hasil belajar Kooperatif sebesar 73,29 lebih baik dari hasil belajar konvensional sebesar 65,68. Dengan demikian dapat disimpulkan bahwa pembelajaran Kooperatif dengan Tipe Student Teams Achievement Division berpengaruh terhadap hasil belajar matematika siswa SMAN 1 Tebing Tinggi

    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

    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

    Developing an instrument to evaluate the influential factors of the success of local curriculum

    Full text link
    The purpose of this study is to create an instrument to evaluate the factors that influence the success of the local curriculum in senior high school. The instrument developed is essential to find out what factors influence the success of the local curriculum. This research is a research and development which consists of three stages: (1) initial investigation, (2) design and validation stages, (3) trials, evaluations, and revisions. The results of small scale trials were analyzed using EFA (Exploratory Factor Analysis), obtaining one invalid item from 32 items. The results of a wide-scale test analyzed using CFA (Confirmatory Factor Analysis) obtained all indicators have loading factors> 0.3 and reliability constructs> 0.7. The results of the analysis show that the developed instrument fits the data obtained in the field. From the constructs of the instrument development, it is indicated that there are nine influential factors, consisting of regional government support, local community support, local industry support, academic community support, student interest, student motivation, practical tools, practical materials, and funds to buy lab material. The instrument developed has been used properly to obtain information about the factors that influence the success of the local curriculum
