Meningkatkan Aktivitas Kolaboratif dan Pemahaman Konsep Mahasiswa pada Perkuliahan Fisika Dasar I melalui Lesson Study
Full text linkThis study aimed to increase students’s collaborative activity and conceptual understanding in Fundamental Physics I course through the implementation of lesson study in two parallel classes. Each lesson study cycle consisted of three stages, started with planning a lesson, teaching and observing the lesson, and reflecting the result, for the first class. After that, revising the lesson plans to be implemented in the second class. The results showed that students’s collaborative activities and conceptual understanding for the two classes increased from cycle I – cycle III. The average scores of first class’ collaborative activity from cycle I - cycle III were 72.0, 75.8, and 81.6, respectively while for the second class were 73.4, 78.8, and 82.6. Moreover, the average conceptual understanding for the first class from cycle I - cycle III were 42.7, 58.8, and 66.2, respectively, while the second class were 48.5, 65.5, and 66.1. The results also showed that the average collaborative activities and understanding the concept of second grade students tended to be better than students of the first class
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
Peningkatan Aktivitas dan Hasil Belajar Siswa pada Pembelajaran IPA dengan Pendekatan Keterampilan Proses
Full text linkThis research aimed to: (1) describe the increase of students’ activity in the skill-based process in science learning, (2) describe the increase of students’ learning achievement in the skill-based process in science learning. This classroom action research has been conducted in three cycles with 29 students of VIIA Class of Junior High School (SMP) Dharma Bakti, South Lampung. Every cycle consist of planning, action and observation, and reflection. The data were collected using multiple choice test for learning achievement and observation sheet for students’ activity. The results showed that process skill approach could increase students’ activity and learning achievement of science from cycle to cycle. The average students’ activity score from the first cycle to the third cycle were 62,1 (sufficient), 70,0 (sufficient), and 77,1 (active), respectively. The average students’ learning achievement from cycle I to cycle III were 62,1 (sufficient), 65,2 (sufficient), 69,7 (good), respectively.

Students’ internet access, internet self-efficacy, and internet for learning physics: gender and grade differences
Full text linkThis paper aims to analyze the differences between internet facilities, internet usage purposes, internet selfefficacy (ISE), and internet perceptions in learning physics, regarding students’ gender and grade. A total of 798 senior high school students were surveyed randomly from 10 schools in the urban area of Lampung Province, Indonesia. The data were analyzed with Chi-square tests, t-test and ANOVA test for parametric, and Mann-Withney test and Kruskal-Wallis test for nonparametric. The results showed that by gender, female students were better at the ownership of computers and internet access via mobile phones. For the purpose of accessing internet, they were also identified more frequently in using internet for academic purposes, social media, and doing physics homework. Additionally, females were better at the perception about the benefit of the internet in learning physics. Besides, males were higher in using internet for entertainment and accessing physics’ video and animation. For experience and frequency in accessing internet and ISE, there were no significant gender differences found. Meanwhile, the differences were found between grades in some general usage as well as in ISE. Overall, the higher the students’ grade, the greater the percentage of students who use them, except in internet perceptio
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
