Analisis Kemampuan Pemahaman Konsep Matematis Siswa pada Materi Persamaan Linear Dua Variabel
Get PDFThis study aims to analyze the understanding of eighth-grade students at SMP Negeri 1 Jeumpa regarding the material on linear equations with two variables. The research subjects consisted of 13 students, and the primary instrument used was a test as the main data and interviews as supporting data. The results showed that 40% of the students had a low level of understanding, indicating significant difficulties in comprehending and applying basic concepts. The study concludes that more interactive and supportive teaching methods are needed to enhance students\u27 understanding of linear equations with two variables.

Student Numeracy Ability in Solving Problems on Geometry and Measurement Material
Get PDFNumeracy is the ability to apply number concepts and arithmetic operation skills in daily life, professional development, and the development of science and technology. Numeracy skills play an essential role in the application of number concepts and arithmetic operations in the context of everyday life. This research aims to determine the numeracy skills of class VIII-B students at SMP Negeri 1 Blangpidie in solving problems on geometry and measurement material. The data collection methods used were tests and interviews. From the research results, of the total 27 students involved, 22 students showed very high numeracy skills, reaching a percentage of 81%. Meanwhile, five other students have a high level of numeracy ability, with a percentage of 19%. The level of numeracy ability of class VIII-B students is assessed based on student indicators in solving problems on geometry and measurement material. It can concluded that the numeracy skills of class VIII-B students in solving geometry and measurement material problems have perfect numeracy scores
Application of Problem-Based Learning (PBL) Learning Model to Improve Student Learning Outcomes in Arithmetic Row Material Class XI SMAN 6 Southwest Aceh
Get PDFIn this era of globalization, the low mathematics learning outcomes of students at the high school level, especially at SMAN 6 Aceh Barat South, are caused by the fact that in the learning process, teachers only focus on using less competent methods, so students get bored easily. The purpose of this study is to determine the completeness of student learning outcomes through Problem-Based Learning on Arithmetic Rows and Series Materials. This research is classified as a classroom action research that is carried out in two research cycles. In each research cycle, there are 4 stages consisting of planning, implementation, observation, and reflection stages. Data collection in the study was carried out using the test method. The data obtained in the study were then analyzed by analytical descriptive analysis techniques and qualitative descriptive analysis. The results of the study showed that the average student learning outcome in the pretest was 65.4 and increased in the post-test, which was 70.9. Based on these results, it can be seen that there is an increase in student learning outcomes in each cycle. Therefore, it can be concluded that the application of the problem-based learning model can significantly improve the mathematics learning outcomes of high school students

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
