MODEL GI-GI (GROUP INVESTIGATION-GUIDED INQUIRY) DALAM PEMBELAJARAN GELOMBANG DI SMA/MA (Studi Pada Hasil Belajar dan Keterampilan Proses Sains Siswa)
No full textArtikel ini melaporkan hasil mengujicobakan model GI-GI (Group Investigation-Guided Inquiry) dalam pembelajaran gelombang di SMA/MA. Tujuan penelitian ini untuk mengkaji pengaruh model GI-GI (Group Investigation-Guided Inquiry) terhadap hasil belajar siswa dalam pembelajaran gelombang dan mendeskripsikan keterampilan proses sains siswa selama menggunakan model GI-GI (Group Investigation-Guided Inquiry) dalam pembelajaran gelombang. Jenis penelitian ini adalah eksperimen menggunakan desain post-test only control group design. Penelitian ini dilaksanakan di SMA Negeri Arjasa pada siswa kelas XI semester genap tahun ajaran 2015/2016 mulai tanggal 2 Mei 2016 sampai 12 Mei 2016. Teknik perolehan data hasil belajar siswa berupa tes tulis melalui post test dianalisis pengujian hipotesis menggunakan Independent Sample T-Test dengan bantuan SPSS 22 dan keterampilan proses sains siswa melalui observasi dan portofolio. Analisis data hasil belajar siswa dalam pembelajaran gelombang tersebut diperoleh nilai sig (2-tailed) ≤ 0,05 yaitu 0,029 ≤ 0,05 maka hipotesis nihil (H0)ditolak dan hipotesis alternatif (H1) diterima. Jadi model GI-GI (Group Investigation-Guided Inquiry) berpengaruh signifikan terhadap hasil belajar siswa dalam pembelajaran gelombang. Persentase rata-rata keterampilan proses sains siswa secara keseluruhan yaitu sebesar 90,3, sehingga disimpulkan keterampilan proses sains siswa selama mengikuti pembelajaran gelombang menggunakan model GI-GI (Group Investigation-Guided Inquiry) termasuk dalam kriteria baik
LKS MULTIREPRESENTASI DISERTAI KARTUN FISIKA DALAM PEMBELAJARAN FISIKA DI MAN 2 JEMBER
No full textTujuan penelitian ini adalah untuk mengembangkan sebuah produk pembelajaran berupa LKS Multirepresentasi disertai Kartun Fisika dalam pembelajaran fisika di SMA/MA. Jenis penelitian ini adalah pengembangan dan menggunakan desain penelitian 4D yang kemudian dimodifikasi menjadi 3D (Define, Design, dan Develop). Penelitian ini dilaksanakan pada bulan April 2016 di MAN 2 Jember pada kelas X IPA 2. Perlunya sebuah bahan ajar yang dapat menjelaskan konsep fisika dengan empat representasi, yaitu representasi verbal, matematik, grafik, dan gambar guna untuk mengukur kemampuan multirepresentasi siswa pada pokok bahasan fluida statis. Metode yang digunakan dalam penelitian ini adalah observasi, dokumentasi, tes, dan wawancara. Tehnik perolehan data menggunakan lembar validasi dan tes. Hasil penelitian menunjukkan bahwa LKS yang dikembangkan berkategori valid dengan skor perolehan rata-rata 87,93% yang diperoleh berdasarkan penskoran dari validator yang dirata-rata berdasarkan aspek penilaian. Kemampuan multirepresentasi verbal, matematik, grafik, dan gambar diuji menggunakan N-gain dengan hasil tes esaay siswa didapatkan nilai sebesar nilai 0,595. Nilai tersebut berada pada rentang ( 0,3≤ g ≤ 0,7 ), sehingga nilai yang didapat berkategori sedang. Prosentase perbedaan skor pre-test dan skor post-test sebesar 36%
PENERAPAN MODEL INKUIRI TERBIMBING (GUIDED INQUIRY) DALAM PEMBELAJARAN FISIKA SMA DI JEMBER(Studi pada Keterampilan Proses Sains dan Keterampilan Berpikir Kritis)
No full textThe research aimed to describe of science process skills students and to assess the effect of guided inquiry learning to physics critical thinking skills students. The research used true experimental with randomized control group only design. Data collection methods used in this research is test, observation, documentation, and interview as supporting data. Data analysis used to test the hypothesis reseach is independent sample t-test in SPSS 22. The results showed 1) guided inquiry learning can be used to train students’ science process skills. The term proved by percentage increase in science process skills of students from the first meeting until third meeting and if the categorized in science process skills criteria already quite good, 2) guided inquiry learning significant effect on students’crtitical thinking skills. It can seen from the significant value (one-tailed) of 0,0015 or ≤ 0,05
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
