Kata Kunci : Hasil Belajar Matematika, Pendekatan Pembelajaran Kontekstual
Skripsi ini membahas tentang pendekatan pembelajaran kontekstual dalam
meningkatkan hasil belajar matematika siswa kelas VII1 SMP Negeri 2 Bua Ponrang.
Penelitian ini merupakan penelitian tindakan kelas (classroom action
research) dengan objek penelitian adalah siswa kelas VII1 SMP Negeri 2 Bua
Ponrang pada semester ganjil tahun pelajaran 2012/2013 dengan jumlah siswa 28
orang. Penelitian ini dilaksanakan sebanyak dua siklus, masing-masing siklus
dilaksanakan sebanyak 4 kali pertemuan. Pengambilan data dilakukan dengan
menggunakan tes hasil belajar, lembar observasi, dan tanggapan siswa . Data hasil
belajar yang terkumpul dianalisis dengan menggunakan analisis kuantitatif dan data
hasil observasi dianalisis dengan analisis kualitatif.
Berdasarkan analisis deskriptif menunjukkan bahwa hasil belajar siswa
setelah penerapan pembelajaran kontekstual menunjukkan bahwa skor rata-rata siswa
pada siklus I sebesar 65,18 atau sebesar 32,14%. Sedangkan pada Siklus II diperoleh
skor rata-rata sebesar 79,18 atau sebesar 89,29%. Hal ini menunjukkan telah tercapai
hasil belajar siswa, dimana nilai KKM yang diterapkan di sekolah jika mencapai nilai
ketuntasan minimal 70 dan 70% yang mencapai nilai 70 tuntas secara klasikal.
Dari hasil penelitian ini dapat disimpulkan bahwa dengan diterapkannya
pembelajaran kontekstual pada siswa kelas VIII SMP Negeri 2 Bua Ponrang dalam
proses pembelajaran, maka hasil belajar matematika siswa dapat meningkat

Evaluation of Mobile Advanced Road Weather Information Sensor (MARWIS) by Lufft for Indiana Winter Road Operations
Full text linkThe students of the Field Infrastructure Assessment course evaluated the Mobile Advanced Road Weather Information Sensor by Lufft on behalf of the Indiana Department of Transportation. The device is mounted on a vehicle, takes roadway condition measurements 100 times per second, and aggregates the measurements into one-second intervals. The data is transmitted real-time to the cloud. The class specifically evaluated the following measurements: road condition, surface temperature, and friction. It was found that the MARWIS temperature reading was systematically 4˚F lower than the probe readings. Skid test empirical results were consistent with the MARWIS friction readings. It was also found, using two devices on the back of the test vehicle, that the friction in the wheel track was greater than the friction in the center of the lane, as expected. Lastly, the “chemically wet” road condition was not consistently observed by MARWIS where expected
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
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
