PENGEMBANGAN INSTRUMEN UJI KOMPETENSI UNTUK CALON GURU MATEMATIKA
Full text linkInstitusi pendidikan akan menjadi berkualitas manakala didukung oleh sumber daya manusia yang berkualitas. Sumber daya yang paling berpengaruh dalam satuan pendidikan tidak lain adalah guru. Untuk menghadirkan sosok guru yang berkualitas harus dimulai dari satuan pendidikan yang menghasilkan guru. Dari sana seharusnya sudah bisa tersaring mana yang bisa jadi guru professional mana yang tidak. Untuk itu perlu adanya filter yang dapat memisahkan antara calon guru berkualitas baik dan yang tidak. Tujuan dari penelitian ini adalah membuat suatu aplikasi yang berguna untuk menguji kompetensi calon guru matematika. Dengan aplikasi ini diharapkan dapat membantu dosen dalam menilai calon guru apakah pantas untuk diluluskan atau masih perlu ditempa. Untuk menghasilkan suatu aplikasi yang dapat diimplementasikan dibutuhkan empat tahapan yaitu: investigasi awal, tahap desain, tahap konstruksi/realisasi dan terakhir adalah evaluasi dan revisi. Tahap investigasi awal menentukan butir soal seperti apa yang ingin dimasukkan kedalam aplikasi. Pada tahap desain merancang tampilan soal dalam aplikasi seperti apa yang baik untuk para calon guru. Dalam tahap konstruksi/realisasi yaitu membuat aplikasi berdasarkan tahapan pertama dan kedua. Tahapan terakhir mengevaluasi dan merevisi kekurangan yang terdapat pada aplikasi yang telah dibuat. Hasil akhir diperoleh sebuah aplikasi ujian berbasis web yang telah teruji dan dinyatakan layak digunakan untuk menguji komptetensi calon guru matematika di Universitas Sembilanbelas November Kolaka.Educational institutions will be of high quality if they are supported by quality human resources. The most influential resource in an educational unit is none other than the teacher. To present a qualified teacher, it must start from the education unit that produces teachers. From there, you should be able to filter out which ones can be professional teachers and which are not. For this reason, it is necessary to have a filter that can separate good quality teacher candidates and those who are not. The purpose of this study is to make an application that is useful for testing the competence of prospective mathematics teachers. With this application, it is hoped that it can help lecturers in assessing prospective teachers whether they are appropriate for graduation or still need to be forged. To produce an application that can be implemented, four stages are needed, namely: the initial investigation, the design stage, the construction/realization stage, and last is evaluation and revision. The initial investigation stage determines what items you want to include in the application. At the design stage, designing the appearance of questions in what kind of application is good for prospective teachers. In the construction/realization stage, namely making applications based on the first and second stages. The last stage is to evaluate and revise the shortcomings contained in the application that has been made. The results of the material evaluation and media evaluation from the two validation teams showed numbers in the good category. The final result is a web-based exam application that has been tested and declared suitable to be used to test the competence of prospective mathematics teachers at the University of Sembilanbelas November Kolaka

Dua diantara LMS yang sudah dikenal oleh masyarakat pelajar yaitu Google Classroom dan Microsoft Teams. Penelitian ini bertujuan untuk membandingkan keefektifan kedua LMS dalam mengelola kelas online agar diperoleh informasi yang lebih jelas tentang kelebihan, kekurangan serta keefektifan masing-masing LMS. Dalam pelaksanaannya peneliti menggunakan dua LMS ini untuk mengajar pada dua kelompok kelas di Universitas Sembilanbelas November Kolaka. Kemudian mengukur dan membandingkan kelebihan dan kekurangan kedua LMS pada beberapa indikator. Instrumen utama dalam menganalisa kelebihan dan kekurangan kedua LMS ini adalah peneliti sendiri. Data diperoleh pada saat proses pembelajaran berlangsung. Semua informasi tentang fungsi fitur kedua LMS dikumpulkan kemudian direduksi sehingga diperoleh data yang jelas yang mempermudah dalam membuat kesimpulan. Data lain berupa hasil belajar mahasiswa juga dikumpulkan menggunakan fitur pengujian masing-masing LMS. Ternyata tidak ada perbedaan yang signifikan antara kedua hasil belajar yang diperoleh. Disisi lain, ada delapan fitur LMS yang masing-masing memiliki keunggulan. Google Classroom unggul dalam hal kecepatan akses, fitur penilaian dan fitur absensi. Microsoft Teams unggul dalam hal penyimpanan data dan komunikasi. Sementara fitur administrasi, pengujian dan penyampaian bahan ajar masing-masing memiliki kelebihan tersendiri untuk kedua LMS masing-masing

The training application is deliberately made web-based to be more flexible because it can be operated using a laptop or using a smartphone. This application is generally intended for junior high school students but is specifically for students of SMP Negeri 1 Tinondo because the participants in the application trial are taken from the school. The software used to create the application is Ispring Suite version 9. The instruments used to collect data are material validation sheets, media validation sheets, and prototypes made. The model used in the problem development is a modification of several development models such as 4D, Plomp, and ADDIE. It is carried out in eight stages, namely: needs analysis, design stage, realization, verification, prototype production, item analysis, revision, and finalization. The results of the development carried out obtained a question bank application that was declared suitable to be used as a preparatory exercise instrument for the final stage of the junior high school mathematics exam. This instrument makes it easier for students to learn through practice questions because it could be accessed via smartphones. This instrument is also a means of habituation in answering web-based questions
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
