Upaya Meningkatkan Proses Dan Hasil Belajar IPA Melalui Model Problem Based Learning Kelas III Sekolah Dasar
Full text linkThis study began with the low student learning outcomes in class III caused by the learning process that is not optimal. This type of research is a classroom action research. This class action research includes the stages of planning, implementation, observation and reflection. The subjects of this study were students in grade III SDN No.152 / II Renah Jelmu with a total of 18 students. Data collection techniques used were tests and observation sheets. The research instruments used included the Learning Implementation Plan with the Problem Based Learning (PBL) model, test questions and observation sheets. The data analysis technique used is descriptive analysis while the research approach is quantitative. The research results obtained are as follows; (a) the teacher conducts learning interactively so that the learning process in cycle I runs well and increases in cycle II with very good criteria. (b) Students become active in the learning process, this is shown from the learning activities of students in the first cycle with good enough criteria and then increase in the second cycle with good criteria. (c) Problem Based Learning Model taught coherently will train students' understanding ability, this can be seen from the results of student learning that increased from cycle I only by 78% to 89% in cycle II with very good criteria.This study began with the low student learning outcomes in class III caused by the learning process that is not optimal.

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
PENINGKATAN PROSES DAN HASIL BELAJAR IPA MENGGUNAKAN MODEL KOOPERATIF SNOWBALL THROWING DI SEKOLAH DASAR
No full textThis research is motivated by the low process and learning outcomes of elementary school students in grade IV SD Negeri No. 002/XI Pasar Sungai Penuh. So it is necessary to do research with the aim of improving the process and learning outcomes of science after using the cooperative model of the snowball throwing type. The research was carried out using classroom action research (CAR) which consisted of two cycles. Each cycle consists of four stages, namely planning, implementation, observation, and evaluation. The subject of this research is the fourth grade students of SD Negeri No. 002/XI Pasar Sungai Penuh as many as 28 people. Data collection instruments in the form of observation sheets and learning outcomes test questions. Analysis of the data used is descriptive qualitative analysis method. The results showed that (1) an increase in the learning process carried out by teachers from the first cycle reached 83% and an increase in the second cycle reached 94.04%. In addition, the student learning process also experienced a very good increase, where in the first cycle it reached 71.4% and increased in the second cycle it reached 89.3%. (2) there is an increase in students' science learning outcomes with the achievement of learning outcomes test scores in the first cycle reaching 76.6% and experiencing a very good increase in the second cycle reaching 88.6%. Thus, the use of the cooperative model of the snowball throwing type can improve the process and learning outcomes of fourth grade science students.This research is motivated by the low process and learning outcomes of elementary school students in grade IV SD Negeri No. 002/XI Pasar Sungai Penuh.

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
