Pembelajaran berbasis sains potensi lokal merupakan penciptaan lingkungan belajar dan perancangan pengalaman belajar yang mengintegrasikan potensi daerah sebagai bagian dari proses pembelajaran dimana potensi lokal yang diintegrasikan terdapat keterkaitan dengan ilmu pengetahuan (sains). Pembelajaran dilakukan dengan mengaitkan konsep biologi dengan potensi lokal yang berada ditengah masyarakat. Penelitian ini dilakukan karena kemampuan siswa dalam menganalisis, dan mengaitkan konsep dengan potensi lokal yang berkembang dalam masyarakat masih rendah. Keadaan ini menyebabkan pembelajaran biologi hanya menuntut siswa untuk menguasai konsep semata dengan metode menghafal. Oleh karena itu, kemampuan siswa dalam bernalar pun menjadi rendah.
Penelitian ini bertujuan untuk mengetahui (1) peningkatan hasil belajar siswa, (2) aktivitas belajar siswa, dan 3) respon siswa terhadap penerapan pembelajaran berbasis sains potensi lokal Tahu Sumedang di kelas X SMAN Jatinunggal. Pendekatan penelitian ini menggunakan pendekatan kuantitatif dengan metode eksperimen. Kelas eksperimen dalam penelitian ini adalah kelas X.2 (30 siswa), dan kelas X.8 (30 siswa) sebagai kelas kontrol. Desain penelitian menggunakan pretest-postest control group design. Teknik pengumpulan data: tes, observasi, dan angket. Data dianalisis dengan dengan uji statistik spss (uji two independent sampel test-Mann Whitney U) .
Hasil penelitian ini menunjukan (1) Hasil belajar kelas eksperimen dan kelas kontrol keduanya menunjukan peningkatan, rata-rata nilai N-Gain kelas eksperimen (0,70) sedangkan rata-rata nilai N-Gain kelas kontrol (0,54). Hasi uji statistik menunjukan bahwa nilai Sig 0.000 < 0.05 artinya Ho ditolak dan Ha diterima, dengan demikian terdapat perbedaan yang signifikan peningkatan hasil belajar antara kelas ekaperimen dan kelas kontrol. (2) Persentase rata-rata aktivitas belajar siswa pertemuan kedua sebesar 77% lebih tinggi dibandingkan pertemuan pertama sebesar 56%. (3) Persentase rata-rata angket respon siswa secara keseluruhan sebesar 79,3% dengan kriteria kuat.
Berdasarkan hasil penelitian di atas disimpulkan bahwa hasil belajar siswa kelas eksperimen meningkat lebih signifikan dibandingkan kelas kontrol, aktivitas belajar siswa kelas eksperimen jauh lebih baik bila dibandingkan kelas kontrol dan siswa merespon dengan baik penerapan pembelajaran berbasis sains potensi lokal.

Get PDFDEWI FITRIYANI. Effect of Student Perceptions About Parenting style Against Emotional Intelligence Skills Class XII Akuntnasi SMKN 8 Jakarta. Economic Education Studies Program, Concentration in Accounting Education, Department of Economics and Administration, Faculty of Economics, State University of Jakarta, in 2016.
This study aims to determine the effect of Student Perceptions About Parenting style Against Emotional Intelligence Skills Class XII Akuntnasi SMKN 8 Jakarta based on data and facts are valid and reliable.
The study was conducted in SMK Negeri 8 Jakarta.Metode used method survey. Populasi affordable in this study were students of class XII program accounting expertise totaling 104 students. Teknik sampling using proportional random sampling to obtain a sample of 83 students. To gather data from the two variables used research instrument shaped Likert scale for Parenting style (Variable X) and Emotional Intelligence (Variable Y) Regression equation in this research is Y = 97.550 + 0.72 X. From this equation test requirements analysis conducted by normality test error estimate the regression of Y on X obtained by Liliefors. Lcount F table (3.96) which
indicates the regression equation means. the result of the correlation coefficient using the product moment of Pearson obtained value rxy0356. this means there is a positive relationship between parenting style with emotional intelligence of students of class XII program accounting expertise SMK Negeri 8 Jakarta. While the measurement of the coefficient of correlation is done for all three indicators of parenting then the results for parenting democratic values rxy0,373 this means there is a positive relationship between parenting style with emotional intelligence of students of class XII program accounting expertise SMK Negeri 8 Jakarta. As for the authoritarian parenting values obtained rxy0,210 this means there is a positive relationship between parenting authoritarian parents with emotional intelligence of students of class XII program accounting expertise SMK Negeri 8
Jakarta. Further to permissive parenting values obtained r xy-090 this means there is a negative relationship between parenting style were permissive with the emotional intelligence of students of class XII program accounting expertise SMK Negeri 8 Jakarta. From t-test calculations obtained t = 3.42> table = 1.99 which indicates a significant relationship between the variables X that parenting style with a variable Y is emotional intelligence. As for the t-test performed on each indicator of the importance of parenting t = 3.62> table = 1.99 which indicates a significant relationship between the variables X that parenting style were democratic with a variable Y is emotional intelligence. Similarly, for the authoritarian parenting obtained t = 1.93> t table = 1.99 which showed no significant relationship between the variables X that authoritarian parenting style with a variable Y is intelligence emosional.Then to permissive parenting obtained t = -0.90> table = 1.99 indicating no significant relationship between the variables X that parenting style are permissive with variable Y of emotional intelligence. From the calculation of determination coefficient of 12.65%, so it can be said that the variable Y emotional intelligence is determined by the variable X parenting style amounted to 12.65%
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

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
