No full textPenelitian ini bertujuan untuk mendeskripsikan: (1) keefektifan implementasi pendekatan scientific dengan model problem based learning ditinjau dari ketercapaian sikap spiritual, sikap sosial, pengetahuan dan keterampilan siswa pada materi bangun ruang sisi datar SMP Kelas VIII Semester 2, (2) keefektifan implementasi pendekatan scientific dengan model learning cycle 5E ditinjau dari ketercapaian sikap spiritual, sikap sosial, pengetahuan dan keterampilan siswa pada materi bangun ruang sisi datar SMP Kelas VIII Semester 2, dan (3) perbedaan keefektifan implementasi pendekatan scientific dengan model problem based learning dan learning cycle 5E ditinjau dari ketercapaian sikap spiritual, sikap sosial, pengetahuan dan keterampilan siswa pada materi bangun ruang sisi datar SMP Kelas VIII Semester 2.
Penelitian ini adalah penelitian eksperimen semu dengan non equivalent (pre-test and post-test) group design. Populasi dalam penelitian ini adalah seluruh siswa kelas VIII SMP N 12 Padang. Sampel dipilih 2 kelas dari 8 kelas secara acak yaitu kelas VIII4 dan VIII5. Instrumen yang digunakan adalah angket sikap spiritual dan sikap sosial, tes pengetahuan, dan tes keterampilan. Untuk mengetahui keefektifan pendekatan scientific dengan model problem based learning dan learning cycle 5E ditinjau dari ketercapaian sikap spiritual, sikap sosial, pengetahuan dan keterampilan siswa, data dianalisis secara univariat dengan statistik uji one sample t-test pada taraf signifikansi 5%. Untuk mengetahui perbedaan keefektifannya diukur dengan uji MANOVA dengan kriteria Hotelling’s Trace pada taraf signifikansi 5%.

Efektivitas Implementasi Pendekatan Scientific dengan Model Problem Based Learning dan Learning Cycle 5E
Full text linkThe purposes of this research are to describe and compare the effectiveness of the imple mentation of scientific approach using problem based learning and learning cycle 5E model viewed from achievement spiritual attitudes, social attitudes, knowledge, and skills of students on polyhedral topic in Junior High School Grade VIII. This research is quasi experiment using nonequivalent (pre-test and post-test) group design. Population in this research are all of students grade VIII Junior High School 12 Padang. The sample was grade VIII4 and VIII5. The instruments used are questionnaires spiritual attitude and social attitude, knowledge and skill test. The results of the research are as follows the implementation of scientific approach with problem based learning and learning cycle 5E model is effective viewed from the achievement spiritual attitudes, social attitudes and knowledge of students, but not effective viewed from students skill, and there are no differences between the effectiveness of the implementation of scientific approach using problem based learning and learning cycle 5E model
Identification of Learning Obstacles on Surface Area of Cube and Cuboid for Junior High School Students
Full text linkBackground of this research was the fact that there are still many students of class VIII SMP N 24 Padang who has learning obstacles in the process of learning mathematics, especially in the field of geometry. The learning obstacles experienced by students were identified through a preliminary study and analysis of learning obstacle identification tests on area of cubes and cuboids, and interviews with class teachers and students. The types of learning obstacles in this study are ontogenic obstacles, didactical obstacles, and epistemological obstacles. The design of this study used a descriptive qualitative research method with learning obstacle identification test instruments on area of cubes and cuboids, and interviews. The subjects of this study were class VIII students of SMP N 24 Padang who took the test and interviews, and mathematics teachers as interview respondents. The results of this study identified learning obstacles consisting of ontogenic obstacles, didactical obstacles, and epistemological obstacle
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
