THE INFLUENCE OF PROBLEM-BASED LEARNING MODEL TO IMPROVE STUDENT LEARNING OUTCOMES IN MATHEMATICS IN CLASS IV UPTD SD NEGERI 73 BARRU DISTRICT BARRU
Get PDFThis research is a type of quantitative research with a pre-experimental research design with a One Group Pretest-Posttest Design which aims to determine student learning outcomes in mathematics before and after using the problem-based learning model. The population in this study were all students of class IV UPTD SD Negeri 73 Barru totaling 30 students. The sample used was 30 students selected by saturated sampling technique. Analysis of the data used is the analysis of descriptive statistical techniques inferential statistical analysis. The results of descriptive statistics obtained from the results of class IV UPTD SD Negeri 73 Barru students before using the problem-based learning learning model were in the poor category and after using the problem-based learning learning model they were in the very good category. Then the results of the hypothesis testing were carried out by testing the Independent Sample T-Test showing a sig value (2-tailed) = 0.000 <0.05 meaning that the independent variable affects the dependent variable in other words H0 is rejected H1 is accepted. Thus it can mean that the problem based learning model learning has an effect on improving student learning outcomes on the material around and rectangular area of Class IV UPTD SD Negeri 73 Barru.This research is a type of quantitative research with a pre-experimental research design with a One Group Pretest-Posttest Design which aims to determine student learning outcomes in mathematics before and after using the problem-based learning model.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
PENGARUH MODEL PEMBELAJARAN KOOPERATIF TIPE TEAM ASSISTED INDIVIDUALLY (TAI) TERHADAP HASIL BELAJAR MATEMATIKA SISWA UPT SD NEGERI 7 WATANG SIDENRENG
Get PDFThis study aims to find out the overview of students' mathematical learning outcomes and the influence of the application of Cooperative Learning Model Type Team Assisted Individually (TAI) on mathematics learning outcomes of UPT SD Negeri 7 Watang Sidenreng students. This study uses a type of pre-experimental design experiment research form one group pretest-posttest. The population in this study was all UPT SD Negeri 7 Watang Sidenreng students, while the sample consisted of 21 students in grade IV. Sampling in this study used the purposive sampling technique. The data collection technique used is multiple choice tests. The data analysis used is descriptive statistics and inferential statistics. The results of the data analysis showed that the results of the fourth grade students of UPT SD Negeri 7 Watang Sidenreng were processed with the average pretest score of 50.52 and the average posttest score of 82.47, which means that the students' learning results improved. Next, the hypothesis test was performed with the Paired Sample T-Test, which showed that H_a was accepted meaning that there was a difference in the mathematical learning outcomes of learning in the classroom of 4th grade UPT SD Negeri 7 Watang Sidenreng students before and after the application of the team assisted individually (TAI) type cooperative learning model. Therefore, it can be concluded that the application of the Cooperative Learning Model Type Team Assisted Individually (TAI) has an effect on the mathematics learning outcomes of 4th grade UPT SD Negeri 7 Watang Sidenreng students
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
