Analisis Kemampuan Komunikasi Matematika Siswa Ditinjau dari Motivasi Berprestasi
Get PDFThe achievement motivation that exists in students needs to be stimulated so as to provide better changes for their learning outcomes. One of the results of learning mathematics can be seen is mathematical communication ability in solving a given mathematical problem. For this reason, this quantitative descriptive research was conductide with aimed to know the differences in students' mathematical communication ability reviewed high, medium, and low achievement motivation. The data was taken using essay test and a questionnaire to 67 students as respondents at SMA Negeri 1 Purbalingga in 2021. The sampling used purposive sampling technique. Data analysis used descriptive and inferential statistics. In inferential statistics, the One Way ANOVA test with alpha 5% was used and continued using the Scheffe method. ANOVA test prerequisites for Normality test analysis using Kolmogorov Smirnov and Homogeneity test. The result are H0 is rejected with a significance value 0.002 < 0.05 or Fh=7,159 > F 0,05;2;64= 3,23 . It means that there are differences in mathematical communication reviewed achievement motivation. Then does post ANOVA test with the result are students who have high achievement motivation better mathematical communication than students with medium and low. Meanwhile, students who have medium and low achievement motivation have the same good mathematical communication ability.Motivasi untuk berprestasi yang ada dalam diri siswa perlu dirangsang sehingga memberikan perubahan yang lebih baik untuk hasil belajarnya. Hasil belajar matematika salah satunya dapat dilihat pada kemampuan komunikasi matematika siswa dalam menyelesaikan suatu permasalahan matematika yang diberikan. Untuk itu, penelitian deskriptif kuantitatif ini dilakukan dengan tujuan untuk mengetahui perbedaan kemampuan komunikasi matematika siswa ditinjau dari motivasi berprestasi tinggi, sedang, dan rendah. Data diambil menggunakan instrumen tes essay dan angket kepada 67 siswa sebagai responden di SMA Negeri 1 Purbalingga tahun 2021. Sampel tersebut diperoleh menggunakan teknik purposive sampling. Analisis data menggunakan statistika deskriptif dan inferensial. Pada statistika inferensial digunakan uji Analysis of Variance (ANOVA) One Way dengan alpha 5% dan dilanjutkan pasca ANOVA menggunakan Metode Scheffe. Uji hipotesis ANOVA One Way dilakukan dengan prasyarat analisis uji normalitas menggunakan Kolmogorov Smirnov dan Uji Homogenitas. Hasil penelitian diperoleh dengan nilai signifikansi sebesar 0,002 < 0,05 atau nilai Fh=7,159 > F 0,05;2;64= 3,23 yang berarti bahwa H0 ditolak, artinya terdapat perbedaan kemampuan komunikasi matematika ditinjau dari motivasi berprestasi. Kemudian dilakukan uji lanjut, diperoleh bahwa siswa yang memiliki motivasi berpretasi tinggi mempunyai komunikasi matematika lebih baik dibanding siswa dengan motivasi beprestasi sedang dan rendah. Sedangkan, siswa yang memiliki motivasi berprestasi sedang dan rendah memiliki kemampuan komunikasi matematika sama baiknya
Emotional Intelligence and Numerical Abilities: How are They Related?
Get PDFThis Ex Post Facto research aims to determine the correlation between emotional intelligence and students' numerical abilities and the strength of the correlation between the two variables. Data collection was carried out on seventh-grade students at MTS N 7 Sleman Yogyakarta with a total of 35 respondents. The sampling technique used was simple random sampling. Respondents were given an emotional intelligence questionnaire and a numerical ability test whereas previously the instruments were tested for validity and reliability. The data analysis technique in this study uses Simple Linear Correlation. Prerequisites that must be met before the significance test is a linearity test and a normality test. Using the product moment/Pearson correlation, the result is that the rxy value is 0.547. Also, obtained the value of sig. of 0.001 4.17 as a result H0 is rejected. This study concludes that there is a positive correlation between emotional intelligence and students' numerical ability with a strength of 0.547. This means that the higher the emotional intelligence possessed, the higher the student's numerical ability. The value of the coefficient of determination (R2) is 29.90%, which means that the emotional intelligence variable affects students' numerical abilities by 29.90%, thus 71.10% is influenced by other variables.Keywords: emotional intelligence, numerical abilities, Pearson correlation.DOI: http://dx.doi.org/10.23960/jpmipa/v23i3.pp918-92
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
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
