Full text linkPermasalahan yang ditemukan dalam pembelajaran matematika di SMAN 8 Mataram adalah hasil belajar siswa yang rendah. Penelitian ini bertujuan untuk mendeskripsikan penerapan discovery learning dengan pendekatan saintifik dalam meningkatkan hasil belajar ruang dimensi tiga pada siswa SMAN 8 Mataram tahun pelajaran 2014/2015. Penelitian ini bertujuan untuk mendeskripsikan penerapan discovery learning dengan pendekatan saintifik dalam meningkatkan hasil belajar ruang dimensi tiga pada siswa SMAN 8 Mataram tahun pelajaran 2014/2015. Model pembelajaran discovery learning dengan pendekatan saintifik adalah suatu rangkaian kegiatan belajar yang melibatkan kemampuan siswa untuk mencari, menyelidiki dan menemukan secara sistematis dan kritis sehingga siswa mendapatkan pengetahuan sendiri. penelitian ini merupakan penelitian tindakan kelas yang dilakukan secara kolaboratif antara guru dan peneliti. Tindakan dilaksanakan dalam dua siklus dengan masing-masing siklus terdiri dari tiga pertemuan. Instrumen yang digunakan untuk mengumpulkan data dalam penelitian ini berupa LKS, soal tes, dan lembar aktivitas guru. Teknik pengumpulan data dalam penelitian ini menggunakan tes dan aktivitas guru. Hasil penelitian menunjukan bahwa: peningkatan hasil belajar siswa kelas X.3 SMAN 8 Mataram setelah mengikuti pembelajaran dengan dengan model discovery learning dengan pendekatan saintifik terlihat bahwa nilai hasil belajar siswa pada siklus I adalah 66,67%, sedangan pada siklus II adalah 78,26%. Oleh karena itu dapat disimpulkan bahwa Oleh karena itu dapat disimpulkan bahwa dengan menerapakan model discovery learning dengan pendekatan saintifik dapat meningkatkan hasil belajar ruang dimensi tiga pada siswa SMAN 8 Mataram
PENGARUH PENGGUNAAN BAHASA IBU DALAM KONTEKS BELAJAR MENGAJAR MATEMATIKA TERHADAP DAYA SERAP DAN MOTIVASI BELAJAR SISWA KELAS VIII SMP NEGERI 1 ROPANG TAHUN PELAJARAN 2016/2017
Full text linkThis study was aimed to find whether or notthe effectiveness of mother tongue have a significant effect towards students’ memory and motivation in learning mathematics at the eight students of SMP Negeri 1 Ropang. In this research, the researcher used quasy experimental research method. The population were all of the eight students at SMP Negeri 1 Ropang. the researcher divided into two classes. A class is as control group was taught by using Bahasa and B class is as experimental group was taught by using mother tongue technique. The data was obtained through pretest, posttest and laerning motivation questionnaires. The first students’ ability was seen from the result of pretest was calculated by using normality test meanwhile the last students’ ability was seen by using posttest. Before using t-test, the researcher used posttest to calculate normality test with chi-quadrate after that the researcher gave the t-test. The result of the research showed that mean score of experimental group was 42 to be 73 meanwhile control group was 25 to be 60. Therefore, the result of t-tes (0,735 )was smaller than t- table (2,017). It means that Ho was accepted and Ha was rejected. So, the researcher can concluded the effectiveness of mother tongue technique was not effective toward students’ memory and motivation in learning mathematics at the eight students of SMP Negeri 1 Ropang in academic year 2016/2017
Difficulties in mathematical language and representation among elementary school students when solving word problems
Full text linkDifficulties in mathematical language and representation were the dominant difficulties in solving word problems for students in elementary school. The research aims to analyze students' mathematical language and representation difficulties when solving word problems. The research subjects were 114 fifth-grade elementary school students selected using a purposive sampling technique with different mathematical abilities. The research was conducted at an elementary school in Sumbawa District, West Nusa Tenggara, Indonesia. Data collection techniques included tests, questionnaires, and interviews. The research results show that students' difficulties in mathematical language were dominant indicators of sentences. Students had difficulties in mathematical representation indicators, which were dominant in symbols. The factors that cause difficulty for high, middle, and lower ability students are unaccustomed to solving word problems and using problem-solving procedures, difficulty with concepts, difficulty with reasoning, difficulty understanding what is known and what is being asked, not being careful in reading the problem, and difficulty with long sentences. Student word problem-solving is in the low category

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
