Berdasarkan hasil analisis data disimpulkan bahwa kualitas pembelajaran matematika siswa kelas VII.1 SMP Negeri 2 Sajoanging meningkat melalui penerapan model pembelajaran kooperatif dengan pendekatan realistik-saintifik. Hal ini ditunjukkan oleh: 1) Meningkatnya rata-rata hasil belajar matematika siswa dari pratindakan ke siklus 1 dan siklus 2, yaitu 71 pada pratindakan meningkat menjadi 78 pada siklus 1 dan 87 pada siklus 2; 2) Meningkatnya persentase siswa yang tuntas belajar (mencapai KKM sesuai yang berlaku di SMP Negeri 2 Sajoanging pada mata pelajaran matematika) dari pratindakan, siklus 1 dan siklus 2 yaitu hanya 3 siswa pada pratindakan menjadi 10 siswa pada siklus 1 dan 18 siswa pada siklus 2. Hal ini berarti pada siklus 2 telah mencapai ketuntasan belajar baik secara individual maupun klasikal; 3) Meningkatnya rata-rata keterlaksanaan pembelajaran dari siklus 1 ke siklus 2 yaitu 3.6 (kriteria baik) pada siklus 1 meningkat menjadi 3.9 (kriteria baik) pada siklus 2; 4) Meningkatnya persentase aktivitas siswa dari siklus 1 ke siklus 2 yaitu 70% (kategori tinggi) pada siklus 1 meningkat menjadi 81% (kategori tinggi) pada siklus 2; dan 5) Meningkatnya persentase respon siswa dari pratindakan ke siklus 1 dan siklus II yaitu hanya 63% mengalami peningkatan pada siklus 1 menjadi sebesar 81% dan 90% pada siklus 2.
ABSTRACT
DARNAWATI. 2019. Improving the Quality of Mathematics Learning through the Application of a Cooperative Model with a Realistic-Scientific Approaches to Grade VII.1 at SMPN 2 Sajoanging in Wajo District (supervised by Suradi Tahmir and Nurdin Arsyad)
This research was conducted at SMPN 2 Sajoanging which aims at improving the quality of mathematics learning in grade VII.1 at SMPN 2 Sajoanging through the application of cooperative learning model with a realistic-scientific approaches.
This is a classroom action research conducted in two cycles. The first cycle was conducted in five meetings and the second in cycle was conducted four meetings. The data collection technique applied in this study were learning outcomes test to discover mathematics learning outcomes of students, observation sheet to observe the implementation of learning and activities of students’ in groups, and questionnaire of student’s response to evamine the students’ response on learning model applied. Data were then analyzed quantitatively and qualitatively.
The conclusions of the study are the quality of student mathematics learning increaser through the application of cooperative learning model with realistic-scientific approaches, proven by: 1) the increase in the average mathematics learning outcomes of students from the pre-action, cycle 1 and cycle 2, than 71 in pre-action improves to 78 in cycle 1 and 87 in cycle 2; 2) the increased percentage of students who completed the learning (achieved the KKM as applicable at SMPN 2 Sajoanging in mathematics subject) from pre-action, cycle 1 and cycle 2 which is only 3 students in pre-action to 10 students in cycle 1 and cycle 2, that only 3 students in pre-action increase to 10 students in cycle 1 and 18 students in cycle 2. It meant that the cycle 2 had achieved good learning completeness individually and classically; 3) the increase in the average of learning implementation from cycle 1 to cycle 2 by 3.6 (good criteria) in cycle 1 improved to 3.9 (good criteria) in cycle 2; 4) the increased percentage of students’ activities from cycle 1 to cycle 2 by 70% (high category) in cycle 1 improved to 81 % (high category) in cycle 2; and 5) the increased percentage of students’ responses from pre-action from cycle 1 tocycle 2, that 63% improved an in cycle 1 to 81% and 90% in cycle 2
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
