Tujuan penelitian ini adalah Untuk mengetahui ketuntasan belajar siswa dalam
belajar matematika melalui strategi pembelajaran student team heroik leadership pada
materi pecahan di kelas VII SMP Budi Satrya Medan T.P. 2014/2015, Untuk
mengetahui ketercapaian tujuan pembelajaran siswa dalam belajar matematika
melalui strategi pembelajaran student team heroik leadership pada materi pecahan di
kelas VII SMP Budi Satrya Medan T.P. 2014/2015, dan Untuk mengetahui hubungan
timbal balik (interaksi) siswa dalam belajar matematika melalui strategi pembelajaran
student team heroik leadership pada materi pecahan di kelas VII SMP Budi Satrya
Medan T.P. 2014/2015.
Pada penelitian ini diambil subjek dari siswa SMP Swasta Biudisatrya Medan,
kelas VII-3 yang berjumlah 36 siswa.
Instrumen penelitian berupa tes dan observasi. Tes yang diberikan terdiri dari 10
tes yang berbentuk essay test sedangkan observasinya sebanyak 20. Tes digunakan
untuk mengukur ketuntasan belajar matematika siswa, dan melihat ketercapaian
tujuan pembelajaran. Sedangkan observasi digunakan untuk mengukur keefektifan
belajar dengan menggunakan strategi Student Team Heroic Leadership.
Dari analisis data diperoleh beberapa hasil perhitungan. Pada tes yang telah
dilakukan, dengan subjek sebanyak 36 siswa dan 10 butir soal essay, keseluruhan
diperoleh rata-rata sebesar 78,47%. Simpangan baku sebesar 12,00. Korelasi XY
adalah 0,45. Dan pencapaian reabilitas tes diperoleh sebesar 0,62 dengan kriteria
“Reabilitas Tinggi”. Sedangkan pada observasi kegiatan siswa saat kegiatan belajar
berlangsung, dengan subjek sebanyak 36 siswa dan 20 point aktivitas siswa,
keseluruhan diperoleh rata-rata sebesar 71,06%. Simpangan baku sebesar 11,50.
Korelasi XY adalah 0,92. Dan pencapaian reabilitas tes diperoleh sebesar 0,96
dengan kriteria “Reabilitas Sangat Tinggi”. Sementara pada tingkat ketuntasan belajar, persentase siswa tuntas sebesar 86,11% dan siswa tidak tuntas sebesar
13,89%.
Melihat persentase ketuntasan belajar siswa, hal ini menunjukkan bahwa analisis
keefektifan belajar matematika dengan menggunakan strategi pembelajaran Student
Team Heroik Leadership adalah sangat baik
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
