KESULITAN BELAJAR SISWAPADA PELAJARAN MATEMATIKA (RANGKUMAN DENGAN PENDEKATAN META-ETHNOGRAPHY)
Full text linkPenelitian ini bertujuan untuk mendeskripsikan secara jelas bagaimana rangkuman laporan hasil-hasil penelitian tentang kesulitan belajar siswa pada pelajaran matematika di sekolah dan bentuk kesulitan yang dominan bagi siswa mempelajari matematika dalam enam tahun terakhir. Metode yang digunakan adalah metode deskriptif, yaitu menganalisis gejala yang ada berdasarkan data yang sudah diperoleh dari berbagai penelitan sebelumnya dan dirangkum dengan pendekatan meta-ethnography. Objek penelitiannya adalah laporan hasil-hasil penelitian guru maupun alumni mahasiswa pendidikan matematika yang memuat masalah kesulitan belajar matematika. Hasil rangkuman menunjukkan bentuk-bentuk kesulitan siswa adalah kesulitan representasi matematis pada materi tertentu atau merepresentasikan informasi dari soal cerita ke dalam kalimat matematika; kesulitan memahami definisi, menerapkan konsep, prinsip, dan algoritma; kesulitan menentukan hubungan dua garis dan menentukan sudut yang terbentuk dalam geometri; kesulitan aspek pengetahuan, pemahaman, dan penerapan soal cerita; kesulitan pemahaman konseptual materi tertentu, tidak memahami hubungan antar konsep, dan tidak memahami arti simbol; kesulitan koneksi matematis dalam menyelesaikan soal operasi hitung aljabar; dan kesulitan dalam menyimpulkan hasil penyelesaian soal
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
ANALISIS KESULITAN BELAJAR SISWA PADA MATERI BANGUN RUANG SISI LENGKUNG DI SMP
Full text linkAbstrak: Tujuan penelitian ini adalah mendeskripsikan kesulitan belajar dan faktor-faktor penyebab kesulitan belajar siswa kelas IX SMP Negeri 1 Sungai Kakap pada materi bangun ruang sisi lengkung. Metode yang digunakan adalah metode deskriptif. Teknik pengumpulan data yang digunakan adalah teknik triangulasi. Dari hasil penelitian diperoleh informasi bahwa siswa tidak mampu: 1) memberikan nama bagian tabung dan unsur-unsur kerucut. 2) mengingat rumus luas dan volume tabung, kerucut, dan bola. 3) menggunakan rumus luas dan volume tabung, kerucut, dan bola untuk menyelesaikan masalah. Hal ini disebabkan karena: a) siswa tidak pernah tertarik dengan bangun ruang sisi lengkung. b) guru tidak menggunakan alat peraga pada saat mengajar materi bangun ruang sisi lengkung. c) metode yang digunakan guru kurang bervariasi, guru hanya menjelaskan materi kemudian memberikan soal latihan. d) siswa tidak memperhatikan penjelasan guru sehingga mengalami kesulitan memahami materi. e) jika menemui kesulitan saat mengerjakan soal, siswa lebih memilih diam tanpa berusaha untuk mencari tahu. Kata Kunci: Kesulitan Belajar, Bangun Ruang, Sisi Lengkung Abstract: The purpose of this research is to describe the difficulties in learning and the factors that cause of it to the 9th Grade students of SMP Negeri 1 Sungai Kakap on material with curved edge. The method used descriptive method. The data collection technique is using the technique of triangulation. From the results of the research were obtained the information that the students are not be able to: 1) giving the name of tube sections and the elements of the cone. 2) remind the formula for the area and the volume of the tube, cone and the ball. 3) using the formula for the area and volume tubes, cones and balls to resolve the problem. This is because: a) students are never interested with curved edge. b) teachers are not using a props when teaching material with curved edge. c) the method which used by the teacher less varied, the teachers only explain the material and then provide practice questions. d) students do not pay attention to the teacher's explanations so they have difficulty to understanding the material. e) if they have a problems during work on the tasks, students prefer to silence without trying to find out the answers. Keywords: Difficulties in Learning, The Space, Curve Edge.
EFEKTIVITAS PENGGUNAAN MEDIA PERMAINAN ULAR TANGGA PADA MATERI OPERASI BILANGAN BULAT DI SMP

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
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
