PENINGKATAN KEMAMPUAN PEMAHAMAN KONSEP MELALUI METODE PENEMUAN TERBIMBING BERBANTUAN SOFTWARE AUTOGRAPH PADA MATA KULIAH KALKULUS PEUBAH BANYAK DI FKIP UMSU
Full text linkAbstract. The purpose of this study was to find out: (1) Is the improvement in students' understanding of mathematical concepts given guided discovery method assisted by software Autograph higher than students who were given guided discovery method learning without Autograph software, (2) Is there an interaction between learning with students' initial mathematical ability to increase the ability to understand student mathematical concepts. This research is a quasi-experimental study. The population of this study is that all classes in the fourth semester mathematics education study program are approximately 184 people. Randomly, two classes were selected from six classes. The experimental class was treated with a guided discovery method assisted by autograph and control class given a guided discovery method without the help of autograph. The instrument used is a description test. Data analysis was performed by analysis of two-way variance (ANAVA). The results showed (1) Increased ability to understand mathematical concepts of groups of students who obtained guided discovery method learning using Autograph software higher than the group of students who received learning through guided discovery methods without software autograph. (2) There is no interaction between the learning model and the initial ability of students to increase the ability to understand students' mathematical concepts.Keywords: ability of concept understanding, Guided Discovery Method, Autograph Software

Full text linkThis research is aimed to know: (1) Whether the increasing of mathematical concept understanding ability students through problem-based learning model assisted Autograph better than the increasing of mathematical concept understanding ability students through problem-based learning model assisted Geogebra, (2) How the interaction between learning and early math ability of student mathematical concept understanding, The population are all students of SMA Free Methodist Medan. Then randomly selected two classes of four classes. The first experimental class were treated by problem-based learning model with assisted Autograph and the second experimental grade treated by problem-based learning model with assisted Geogebra. Data analysis was performed by analysis of variance (ANOVA) and two lanes. The research shows that: (1) The increasing of mathematical concept understanding abilities students through problem-based learning model assisted Autograph better than the increasing of mathematical concept understanding abilities students through problem-based learning model assisted Geogebra. (2) There is no Interaction between learning and early math ability of student mathematical concept understanding ability
PENINGKATAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA TERBUKA MELALUI PENDEKATAN INVESTIGASI BAGI MAHASISWA PRODI PENDIDIKAN MATEMATIKA FKIP UMSU PADA MATAKULIAH TEORI BILANGAN
Full text linkAbstract. The research objectives are: (1) Knowing whether the approach to the mathematical investigation can improve the ability to solve open mathematical problems; (2) Knowing how the level of activity of students and lecturers in learning through a mathematical investigation approach. This type of research is Class Action Research. The research subjects were Students of Mathematics Education FKIP UMSU Academic Year 2018/2019. The object of research is the ability of lecturers to manage student learning and activities in the implementation of learning and the ability of students to solve open mathematical problems through an investigative approach to material numbers. The results of the study show that (1) The approach to the mathematical investigation can improve students' mathematical problem-solving abilities; (2) The approach to the mathematical investigation can increase the level of student activity. From the results of the initial test the ability to solve open mathematical problems an average value of 3.17, the average value of student cycle I tests is 10.73 (56.66%) students who have the ability to solve open mathematical problems and average test scores the second cycle was 12 (83.33%) students who had the ability to solve open mathematical problems. Based on the conclusions above, this study suggests that consider the application of a mathematical investigation approach in order to improve the quality of mathematics learning.Keywords: Mathematical Investigation, Problem-Solving, Open-Mathematics
PEMANFAATAN MASJID AL-IKHLAS SEBAGAI SENTRA BIMBINGAN BELAJAR DI KELURAHAN GELUGUR MEDAN TIMUR
Full text linkThe COVID-19 pandemic has had a serious impact on all life on earth. The world of education, including other sectors, must adapt quickly. Likewise in terms of education must adapt in tackling this pandemic. One of the efforts made in tackling this pandemic is by holding tutoring for students, especially elementary school students who have only received learning through gadgets or whatsapp media by their teachers without getting an explanation beforehand so they don't understand what they are studying. This community service was carried out at the Al-Ikhlas Mosque in the neighborhood of Gelugur Darat, Medan Timur. The method used in the form of providing tutoring for one month. The results obtained in the provision of tutoring is a positive response from the National Mosque Council and parents of students. Parents are very supportive and greatly helped by the existence of tutoring which is carried out free of charge. Another result is that students learn to be independent in doing school assignments, and some of them are able to read and count
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
