Selama proses pembuatan perangkat pembelajaran, peneliti juga mendesain
dan mengembangkan lembar validasi, lembar observasi aktivitas guru dan siswa yang
akan digunakan selama pembelajaran berlangsung, dan angket respon siswa. Validasi
perangkat dilakukan oleh 1 Dosen Matematika FKIP Universitas Jember yaitu Drs.
Totok Bara Setiawan, M.Si dan 2 guru matematika SMP Negeri 5 Jember yaitu Ir.
Djarot Martono H., A.Md., Pd dan Mohamad Subarno, S.Pd., M.Pd.
Hasil validasi perangkat pembelajaran yang meliputi Rencana Pelaksanaan
Pembelajaran
minat siswa terhadap pembelajaran, serta angket respon guru dalam pembelajaran
telah memenuhi kriteria kevalidan atau kelayakan dengan skor 0,86 dan 0,95.
Perangkat dan instrumen tersebut dikatakan valid atau layak karena skor atau
koefisien validitasnya lebih dari 0,60 yang berarti koefisien validitas tinggi atau
sangat tinggi.
Langkah setelah validasi adalah uji coba perangkat. Uji coba dilaksanakan
pada tanggal 27 April 2012 sampai 5 Juni 2012 di SMP Negeri 5 Jember kelas VII A
dan VII D. Adapun data yang diperoleh adalah aktivitas guru di kelas VII A dalam
menerapkan pembelajaran matematika di dalam kelas pada pertemuan pertama
sampai pertemuan keenam mencapai 88,17%, sedangkan aktivitas guru di kelas VII D
dalam menerapkan pembelajaran matematika di dalam kelas pada pertemuan pertama
sampai pertemuan keenam mencapai 92,17%. Pada pertemuan di kelas VII D artinya
menunjukkan kategori cukup baik dalam peningkatan aktivitas guru setiap kali
pertemuan. Dengan demikian aktivitas guru dapat dikatakan telah sesuai dengan
langkah-langkah pembelajaran matematika di dalam kelas. Sedangkan keaktifan
siswa kelas VII A pada pembelajaran pertama sampai enam mencapai 83,18% dan
siswa kelas VII D pada pertemuan pertama sampai enam mencapai 83,74%.
Persentase keaktifan tersebut menunjukkan kategori baik dan sangat baik, artinya
sebagian besar siswa aktif mengikuti pembelajaran matematika di dalam kelas. Hasil
belajar menunjukkan peningkatan nilai rata-rata hasil tes akhir siswa kelas VIIA
mencapai 75,66 dan tidak lebih dari 13% siswa mendapat nilai ujian kurang dari 7
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

Kemampuan berpikir kreatif siswa secara klasikal pada Siklus I sebesar 62,16% dan 89,18% pada Siklus II. Hasil kognitif siswa pada Siklus I sebesar 64,86 dan 86,48% pada Siklus II. Hasil afektif/sikap kreatif siswa pada Siklus I sebesar 71,33%, dan 85% pada Siklus II. Hasil psikomotor siswa pada siklus I sebesar 66,45% dan 82,59% pada Siklus II. Aktivitas guru pada Siklus I sebesar 70,45% dan 90,9% pada Siklus II. Aktivitas siswa pada Siklus I sebesar 71,87%, dan 91,66% pada Siklus II. Respon positif siswa pada Siklus I sebesar 81,89%, dan 83,24% pada siklus II. Dalam penelitian tentang penggunaan model inkuiri untuk meningkatkan kemampuan berpikir kreatif siswa, terdapat 4 saran yang diberikan, yaitu; a) guru disarankan untuk menggunakan model inkuiri karena melalui inkuiri dapat memberikan pembelajaran yang bermakna bagi siswa, b) dalam pembelajaran inkuiri guru berperan sebagai fasilitator dan pembimbing serta melibatkan siswa secara maksimal, c) untuk meningkatkan kemampuan berpikir kreatif dengan model inkuiri, guru harus menyesuaikan dengan materi yang disampaikan, d) pada pembelajaran inkuiri guru bukanlah satu – satunya sumber informasi, sumber informasi diharapkan berasal dari buku – buku lain yang lebih bervariasi
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
EFL learners’ problems in listening comprehension of TOEFL test
Full text linkThe intensity of listening as teaching English can affects students' habit of listening to conversations and texts in English. One of a way to help students’ found their best strategy in listening is by analyzing students’ difficulties toward listening comprehension. This research aims to analyze the problems encountered by students of the English Education Department in listening comprehension during the TOEFL test and to explain strategies used by students in the listening section of the TOEFL test. This qualitative research was conducted on students of the Class-A English Education Department in the academic year of 2017 at Walisongo State Islamic University, Semarang, and took 15 students as participants in doing the questionnaire and interview. This research used a questionnaire adapted from Arafat Hamouda and interview guidelines as an instrument in collecting the data. The result of this research reveals that there are several problems encountered by students of the English Education Department in listening comprehension during the TOEFL test including Listening Problems Related to Content such as Unfamiliar Topics, Lack of Vocabulary, Long Spoken Text, and Form of Expression. Problems Related to the Students such as Fear Before Doing Listening, Lose Concentration, Infer Meaning, Unclear Pronunciation, Encounter Unknown Words. Last, Problems Related to Physical Setting such as speed of speech, Poor Audio/CD Quality. As for strategies used by students to listening comprehension of TOEFL test are Before Listening and While Listening such as a). Pay attention to the second speaker b). Choose the answer with synonym c). Guess the question by looking at multiple choices d). Pay attention to 5W+1H e). Overcome panic. The results of this study are expected to provide contributions in information and inputs in learning and teaching listening comprehension as a foreign language. By points out the difficulties encountered by the students in listening comprehension of TOEFL test, it might extend awareness to the teachers and the learners that experience student difficulties gave contribute to teaching and learning to listening comprehension in the future
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
