MATEMATIKA SISWA PADA POKOK BAHASAN
SISTEM PERSAMAAN LINEAR DUA VARIABEL
DENGAN MENGGUNAKAN MODEL PEMBELAJARAN
QUANTUM TEACHING
Penelitian ini dilatar belakangi oleh hasil belajar matematika siswa kelas
VIIIA MTs PUI Rajagaluh pada pokok bahasan sistem persamaan linear dua
variabel yang masih relatif rendah. Berdasarkan wawancara nilai rata-rata siswa
yaitu 59.5 dan sebagian besar siswa belum mencapai nilai KKM yang ditetapkan
oleh guru mata pelajaran matematika. Pada proses pembelajaran sistem persamaan
linear dua variabel guru menggunakan metode yang sama dengan materi lain yaitu
metode konvensional. Rendahnya hasil belajar siswa dipicu aktivitas siswa pada
proses pembelajaran matematika berlangsung tidak baik seperti mengganggu
teman, tidak memperhatikan guru dan tertidur pada proses pembelajaran
berlangsung. selain itu juga, siswa belum terbiasa belajar kelompok. Berdasarkan
hal tersebut peneliti menerapkan model pembelajaran Quantum Teaching sebagai
upaya untuk meningkatkan hasil belajar siswa baik secara kognitif maupun
afektif.
Tujuan penelitian ini adalah untuk mengetahui hasil belajar siswa pada
pokok bahasan sistem persamaan linear dua variabel terhadap model pembelajaran
Quantum Teaching.
Metode penelitian yang digunakan peneliti adalah penelitian tindakan kelas.
penelitian ini menggunakan instrumen tes yaitu untuk mengukur hasil belajar
siswa pada ranah kognitif. Observasi yaitu untuk mengetahui hasil belajar siswa
pada ranah afektif. Subjek penelitian ini adalah siswa kelas VIIIA MTs PUI
Rajagaluh yang berjumlah 37 siswa terdiri dari 21 laki-laki dan 16 perempuan
serta berkolaborator dengan 1 guru matematika dan 1 observer.
Model pembelajaran Quantum Teaching yang dilakukan peneliti
berdasarkan TANDUR yaitu Tumbuhkan, Alami, Namai, Demonstrasikan, Ulangi
dan Rayakan. Pembelajaran dengan model pembelajaran Quantum Teaching akan
membuat siswa menumbuhkan rasa ingin tahunya, percaya dirinya, motivasinya
dalam belajar, mengalami sendiri dalam proses pembelajaran, dan
mendemonstrasikan hasil pekerjaannya, pemikirannya, dan gagasannya di depan
kelas. Penelitian ini dilakukan oleh peneliti dan kolaborator sebanyak tiga siklus.
Hasil penelitian menunjukan peningkatan dari setiap siklus dengan melihat
hasil belajar siswa pada ranah kognitif yaitu siklus I sebesar 62.2% tuntas belajar
dengan nilai rata-rata 66.01, siklus II sebesar 78.4% tuntas belajar dengan nilai
rata-rata 70.28 dan siklus III sebesar 89.2% tuntas belajar dengan nilai rata-rata
78.28. Hasil belajar ranah afektif nilai rata-rata siklus I sebesar 58.9%, siklus II
sebesar 75.9% dan siklus III sebesar 88.4%.
Hasil penelitian ini dapat disimpulkan bahwa model pembelajaran Quantum
Teaching dapat meningkatkan hasil belajar siswa di kelas VIIIA MTs PUI
Rajagaluh pada pelajaran matematika pokok bahasan sistem persamaan linear dua
variabel untuk diterapkan dalam proses pembelajaran sehari-har
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
APPLICATION OF THE HAVERSINE DISTANCE METHOD TO THE JOB AND VACANCIES SEARCH SYSTEM IN THE ENTERTAINMENT SECTOR IN INDONESIA
Full text linkThe International Monetary Fund (IMF) projects that the poverty rate in Indonesia will reach 5.2% by 2024, ranking 59th in the world, Indonesia is the country in Southeast Asia with the highest poverty rate. The second highest poverty rate is in 2023. The percentage is projected to reach 5.3% this year. According to the Central Statistics Agency (BPS), in August 2023 the number of open unemployment in Indonesia will reach 7.86 million people, equivalent to 5.32% of the total national workforce. The Philippines will face the highest poverty rate in the region, followed by Indonesia next with a poverty rate of 5.4%. By 2023. this high poverty rate reflects the urgent need to create jobs. Therefore, the author conducted this research with the aim of addressing the problem of high unemployment rates through a centralized platform that offers job search features and vacancies based on the nearest location for job seekers and providers in the entertainment field, which can be accessed anytime and anywhere. The result of this research is an android application that can facilitate and assist in finding or providing jobs. Through this research the author can contribute to the growth of the entertainment industry in Indonesia, creating new income opportunities for individuals with skills that are usually performed on-site such as singers, magicians, comedians, models, presenters, and other talents in the entertainment sector. This study adopts a qualitative approach, uses the prototype method in the development of the application and applies the Haversine method to calculate the distance between two coordinate points. Thus this study can make a positive contribution in addressing the unemployment problem and increasing job opportunities in the entertainment sector in Indonesia
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
