PROSES TRANSPOSISI DIDAKTIK PADA KONSEP LINGKARAN DI SMP
Get PDFTransposisi didaktik merupakan peralihan pengetahuan dari pengetahuan itu
direkonstruksi/ dipelajari menjadi pengetahuan itu disusun dan diajarkan dalam konteks kelas. Peralihan pengetahuan yang dimaksud berkaitan dengan konsep lingkaran di SMP dari konsep itu direkonstruksi oleh peneliti dan guru menjadi konsep itu disusun dan diajarkan. Penelitian kualitatif dengan pendekatan fenomenologi ini bertujuan untuk menganalisis proses transposisi didaktik pada konsep lingkaran di SMP. Konsep lingkaran
yang ditransposisikan sejatinya sesuai dengan konsep lingkaran menurut scholarly knowledge, dan walaupun tidak tampil sebagai scholarly knowledge tetap mempertahankan unsur-unsur utamanya. Hasil penelitian terhadap analisis sumber data dari studi dokumentasi, observasi, rekaman audiovisual, tes dan wawancara menunjukkan bahwa konsep lingkaran yang direkonstruksi peneliti maupun peneliti dan guru meliputi definisi lingkaran, istilah-istilah yang berkaitan dengan lingkaran, sudut pusat dan sudut keliling, dan konsep panjang busur. Proses transposisi didaktik dari konsep lingkaran yang direkonstruksi oleh peneliti dan guru menjadi desain mengalami penyesuaian yaitu konsep disajikan lebih sederhana dan mengjangkau kognitif siswa, menyesuaikan konsep yang sudah dipelajari siswa sebagai alat konseptual, dan menyesuaikan learning obstacle dari
pembelajaran sebelumnya. Sedangkan implementasi yang dilakukan sudah sesuai dengan desain pembelajaran yang memuat 4 situasi dan konsep perbandingan senilai yang digunakan sebagai alat konseptual sangat sesuai untuk mengkonstruksi konsep panjang busur. Kemudian, pemahaman siswa sebagai dampak dari desain yang diimplementasikan memiliki ragam penyelesaian masalah dalam menghitung panjang busur bahkan terdapat
kekeliruan. Hal tersebut sebagai dampak dari sajian materi yang tidak lengkap berkaitan dengan penyelesaian masalah perbandingan senilai dalam bentuk modifikasi aritmatikanya (hambatan didaktik) dan masalah yang diberikan terlalu sulit bagi siswa (hambatan ontogenik konseptual).
Kata Kunci: Transposisi Didaktik, Konsep Lingkaran
Didactic transposition is a transmission of knowledge from knowledge that is reconstructed or learned into knowledge that is arranged and taught in a classroom context. The transmission of knowledge in question is related to the concept of circles in junior high schools, from the concept being reconstructed by researchers and teachers into being arranged and taught. This qualitative research with a phenomenological approach aims to
analyze the didactic transposition process of the circle concept in junior high school. The concept of a circle that is transposed is actually in accordance with the concept of a circle according to scholarly knowledge, and although it does not appear as scholarly knowledge it still maintains its main elements. The results of the research on the analysis of data sources from documentation studies, observations, audiovisual recordings, tests and
interviews show that the concept of the circle reconstructed by researchers and researchers and teachers consists of the definistion of circle, the terms related to the circle, the center angle and circumferential angle, and the length arc. The didactic transposition process from the circle concept reconstructed by the researcher and the teacher into design underwent an
adjustment , namely the concept is presented more simply and reach student’s cognitive, adjust the concepts students have learned as a conceptual tool, and adjust the learning obstacle from previous learning. Meanwhile, the implementation is in accordance with the learning design which contains 4 situations and the concept of direct proportion used as a
conceptual tool is very suitable for constructing the concept of arc length. Then, students' understanding as the impact of the implemented design has a variety of problem solving in calculating arc length there are even mistakes. This is a result of the incomplete presentation of the material related to solving the direct proportion problem in the form of modification of its arithmetic (didactical obstacle) and the problems given are too difficult
for students (conceptual ontogenic obstacle).

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.
