Analysis of Students\u27 Analytical Thinking Ability in Solving Number Content Numeration Problems
No full textThis study aims to describe the analytical thinking skills of class VIII A students of MTs N 1 Sarolangun in the 2024/2025 academic year in the second semester. Analytical thinking skills include identification, understanding, analysis, and problem-solving in an orderly and logical manner. The method used is descriptive qualitative. The instruments used in this study were tests and interviews. Data collection techniques in the form of analytical thinking ability tests for 27 students and interviews for six students. Data analysis was carried out through data reduction, presentation, and conclusion. The study results showed that students with analytical thinking skills were still in three categories, namely low, medium, and high analytical thinking skills. However, slightly more are in the medium category that meets the differentiating and organizing indicators. Therefore, learning improvements are needed to improve analytical thinking skills
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
The impact of discrete mathematics lectures on students' deductive reasoning: The case of graph theory learning
No full textThis research aims to investigate the impact of the discrete mathematics lecture process on deductive reasoning abilities, especially in carrying out proofs in graph theory. This research uses qualitative research based on the results of observations of the learning process in the Discrete Mathematics course. The subjects of this research were three students from the Mathematics Education Study Program who were pre-service teachers and in-service mathematics teachers at a university in Malang. The data collection technique is a description and observation test question sheet. The research results show that the process of learning graph theory in discrete courses is through explanations related to the definition of graph coloring, examples of the application of theorems, practice questions through guided proof with lecturers, and the application of graph coloring theory in everyday life. Overall, the graph theory learning process emphasizes deductive reasoning abilities. Based on the results of the analysis of the four-color theorem test, in general, it succeeded in having a good impact on students in the mathematics education study program
Analisis Efektivitas Pembelajaran Berbasis STEM dalam Meningkatkan Pemahaman Konsep Matematis
No full textPenelitian ini bertujuan untuk mengevaluasi dampak aktivitas belajar siswa terhadap kemampuan pemahaman konsep matematika melalui penerapan pendekatan pembelajaran STEM dengan model berbasis PBL pada materi SPLDV. Jenis penelitian yang dilakukan adalah Quasi Eksperimen. Populasi siswa dalam penelitian ini berjumlah 92 orang, tersebar di dalam 3 kelas, dengan 2 kelas (VIII A dan VIII C) dipilih sebagai sampel menggunakan metode acak kelas. Teknik pengumpulan data melibatkan tes dan observasi, dengan instrumen penelitian berupa tes pendahuluan dan tes akhir untuk mengukur kemampuan pemahaman konsep matematika serta lembar observasi untuk menilai aktivitas belajar siswa. teknik analisis data yang digunakan adalah uji ANOVA dua arah. Hasil penelitian menunjukkan bahwa model Pendekatan Pembelajaran STEM berbasis PBL memiliki pengaruh signifikan terhadap kemampuan pemahaman konsep matematika. Sebaliknya, tidak terdapat pengaruh yang signifikan dari aktivitas belajar siswa terhadap kemampuan pemahaman konsep matematika. Selain itu, tidak ditemukan interaksi yang signifikan antara model Pendekatan Pembelajaran STEM berbasis PBL dan aktivitas belajar siswa terhadap kemampuan pemahaman konsep matematika. Dengan demikian, dapat disimpulkan bahwa terdapat pengaruh langsung positif dari struktur kognitif terhadap kemampuan pemahaman konsep matematik

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
