Efektivitas model pembelajaran learning cycle 5e (LC5E) dengan pemanfaatan alat peraga pada materi pokok bidang datar terhadap hasil belajar peserta didik kelas VII SMP Nurul Islam Semarang tahun pelajaran 2010/2011
Full text linkPembelajaran matematika SMP Nurul Islam Semarang kurang efektif khususnya pada pokok bahasan segitiga. Hal ini dikarenakan dalam proses pembelajaran masih menggunakan metode konvensional atau ekspositori, guru mencatatkan materi, memberi tugas kemudian peserta didik mengerjakan. Sehingga peneliti tertarik untuk menerapkan model pembelajaran Learning Cycle 5E (LC 5E) pada proses pembelajaran di SMP Nurul Islam Semarang. Permasalahan dalam penelitian ini adalah: apakah model pembelajaran Learning Cycle 5E (LC 5E) dengan pemanfaatan alat peraga pada materi pokok bidang datar efektif dalam meningkatkan hasil belajar peserta didik kelas VII SMP Nurul Islam Semarang tahun Pelajaran 2010/ 2011.
Penelitian ini bertujuan untuk mengetahui: efektivitas model pembelajaran Learning Cycle 5E (LC 5E) dengan pemanfaatan alat peraga pada materi pokok bidang datar terhadap hasil belajar peserta didik kelas VII SMP Nurul Islam Semarang tahun Pelajaran 2010/ 2011. Penelitian ini adalah penelitian eksperimen. Populasi penelitian ini adalah peserta didik kelas VII semester 2 SMP Nurul Islam Semarang yang terbagi dalam tiga kelas dan masing-masing kelas terdiri dari 31 peserta didik. Design yang digunakan dalam penelitian ini adalah “Two-group Post-Test-Only Design”, yaitu menempatkan subyek penelitian ke dalam dua kelompok dengan kategori kelas eksperimen dan kelas kotrol. Dengan menggunakan cara cluster random sampling (acak) untuk memilih anggota kelompok (kelas). Pada kelas eksperimen diberi perlakuan dengan model pembelajaran Learning Cycle 5E (LC 5E) dan kelas kontrol dengan pembelajaran konvensional.
Hasil penelitian menunjukkan bahwa pembelajaran dengan menggunakan model (LC 5E) efektif dalam meningkatkan hasil belajar peserta didik pada materi pokok bidang datar kelas VII. Hal ini terbukti dari nilai kesamaan rata-rata peserta didik sebelum diberi perlakuan, yaitu pada kelas eksperimen adalah –t = 2,00 < t = 0.82 < t = 2,00, nilai kesamaan rata-rata setelah diberi perlakuan pada kelas eksperimen adalah. –t = 2,0000 < t = 2,201 < t = 2,00.. Berarti nilai kesamaan rata-rata setelah diberi perlakuan labih besar dari nilai kesamaan rata-rata sebelum diberi perlakuan. Nilai rata-rata pada kelas eksperimen adalah 73,45 sedangkan nilai rata-rata kelas kontrol adalah 64,90. Dengan demikian dapat disimpulkan pada penggunaan model pembelajaran Learning Cycle 5E (LC 5E) dengan pemanfaatan alat peraga efektif dalam meningkatkan hasil belajar peserta didik dibandingkan dengan penggunaan metode konvesional.
Hasil penelitian ini diharapkan akan menjadi bahan informasi dan masukan bagi para civitis akademika, para tenaga pengajar khususnya bidang matematika. Serta mampu memberikan semangat dan sikap positif terhadap pembelajaran matematika agar senantiasa berprestasi dengan bai
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
Implementasi Manajamen Waktu Pada Mahasiswa Yang Bekerja Paruh Waktu Di Kota Semarang
Full text linkABSTRAK Fenomena mahasiswa yang bekerja paruh waktu merupakan isu global yang kompleksdengan dampak positif dan tantangan signifikan terkait keseimbangan antara studi danpekerjaan.

These strategies enable them to balance academic and work demands andmaintain productivity and psychological well-being. However, challenges such as physical andmental fatigue, social distractions, and unexpected changes in class schedules remain obstacles thataffect concentration. The study emphasizes the importance of professionalism and self-control intime management among part-time students
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
