Full text link(Description of Comprehension of Fractional Material of Grade VII At Junior High School 1 Salomekko)
ABSTRACT
This study is descriptive qualitative research, which aims at describing the relational and instrumental comprehension of grade VII students at SMPN 1 Salomekko in fractional material. Four students were chosenas the subject of the study based on the result of diagnostic test. Data were collected by employing diagnostic test and semi structure interview. Data were analyzed by using descriptive qualitative analysis.
The result of the study reveal that students who had relational comprehension were able to answer questions of fractional material by connecting sevelar concepts and able to provide rational reasons from answers given. Student who had instrumental comprehension answered the questions of fractional material from memorization and unable to provide answers given. The result of the study also reveals that was fairly difficult students who had relational comprehension compared to students who had instrumental comprehension; proven by this research that only one student discovered who had relational comprehension.
The relational comprehension referred to the ability of someone to use mathematical procedure from connecting various mathematical concepts; whereas, instrumental comprehension referred to the ability of someone in using mathematical procedure to solve a problem without comprehending why the procedure could be used; in other words, students who had instrumental comprehension memorized only the formula.
Keyword: comprehension, relational, instrumental, fractional.
ABSTRAK
Penelitian ini adalah penelitian deskriptif-kualitatif yang bertujuan untuk mendeskripsikan pemahaman relasional dan instrumental siswa kelas VII SMP Negeri 1 Salomekko pada materi pecahan. Dalam penelitian ini terpilih subjek penelitian sebanyak 4 siswa yang ditentukan berdasarkan hasil tes diagnostik. Data dikumpulkan dengan metode tes diagnostik dan wawancara semi tersruktur. Metode analisis yang digunakan adalah analisis deskriptif kualitatif.
Hasil penelitian menunjukkan bahwa siswa yang memiliki pemahaman relasional mampu menjawab soal-soal materi pecahan dengan mengaitkan beberapa konsep serta mampu memberikan alasan yang rasional dari jawaban yang diberikan. Sementara siswa yang memiliki pemahaman instrumental menjawab soal-soal materi pecahan berasal dari hafalan serta tidak mampu memberikan alasan dari jawaban-jawaban yang diberikan. Hasil penelitian juga menunjukkan bahwa cukup sulit menemukan siswa yang memiliki pemahaman relasional dibandingkan siswa yang memiliki pemahaman instrumental. Terbukti pada penelitian ini, hanya ditemukan 1 siswa yang memiliki pemahaman relasional.

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
The Effect of Technology In Mathematics Learning: Peran Teknologi dalam Pembelajaran Matematika
No full textThis study aims to describe the role of technology in the implementation of mathematics learning. This writing is based on a literature review of journal articles. It is concluded that the use of technology in learning mathematics has a positive impact. Technology can be used as a source of student learning. Technology can visualize abstract mathematical objects into concrete objects that are easily accessible to students. There are various platforms that support the learning process without time limits and various applications that can be used as a learning space for the teacher\u27s role. However, it is undeniable that technology can have a bad effect on students, for example technology provides easy information for students in terms of instant answers available on the internet and even the use of technology can reduce algebraic abilities. Minimizing this impact requires the ability of HOTS in the implementation of mathematics learning and changing the views of teachers and students towards technology, making technology a partner in learning mathematics. The use of technology with the right use can have a better impact on learning mathematics

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
