Students’ Science Process Skills Through Generative Learning Model In the Topic of Light
Get PDFScience process skills is important to developing the quality of students’ learning in science. This research aimed to determine the effect of generative learning xmodel on students' science process skills of the topic Light. This type of research was pre-exprimental with One Group Pretest-Posttest Design. The population of this research consisted of all students of class VIII in SMPN 5 Singkawang City. The research samples consisted of the students of class VIII E the total number of 20 students and the sampling technique used was simple random sampling. The research instrument used in this research was description test. Data were analyzed by using paired t-test. From the calculation results was obtained the value of -tobtained < -tcritical or -21.36 < -2.093, then Ho was rejected and Ha was accepted at the level of significance α = 0.05. So it can be concluded that there was an effect of generative learning model on students’ science process skills in the topic of Light
Peningkatan Keterampilan Berpikir Kritis Siswa Melalui Penerapan Model Generative Learning pada Materi Hukum Newton
Get PDFThis study aimed to describe the improvement of students' critical thinking skills in Newton's Law subject after generative learning model was implemented. The type of this research was pre-experimental research with One Group Pretest-Posttest Design. The population of this study was all eighth grade students of MTs Makarim Al-akhlak, Singkawang City. The sampling technique used was saturated sampling. The research instrument used was a description test. The data obtained was not normally distributed, so the data was analyzed using non-parametric statistical test namely Mc Nemar Test. From the calculation results, it was obtained the value of χ2obs. > χ2c.v. or 6.125 > 3.841, then H0 was rejected and Ha was accepted at the significance level α = 0.05. Therefore, it could be concluded that there was an improvement in students' critical thinking skills in Newton's law subject after generative learning model was implemeted
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
Development of Fluid Viscosity Coefficient Apparatus Based On jetAudio and Subtitle Edit
Get PDFThe purpose of this research was to develop a fluid viscosity coefficient apparatus using computer application that is easily obtained and used, namely jetAudio and Subtitle Edit software. The research was conducted at Physics laboratory in STKIP Singkawang and 5 secondary schools in Singkawang City. The feasibility level of this apparatus is known through validation by experts. Validation was carried out by 3 physics lecturers. The results of the validation stage were used for user tests by 10 STKIP Singkawang students. From the results of the analysis obtained 1) the results of validation by tool experts amounted to 91.1% which were interpreted very good, 2) the results of validation by material and content experts amounted to 91.9% which were interpreted very good, and 3) the results of user tests conducted by students showed the percentage of responses at 71.35% which was interpreted good. Thus the apparatus is feasible to use and can be an alternative in physics learning that can improve students' skills and conceptual understanding
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
Pengaruh Model Generative Learning Terhadap Hasil Belajar Ranah Kognitif Siswa Pada Materi Hukum Newton
Get PDFPenelitian ini bertujuan untuk mengetahui pengaruh model <em>generative learning</em> terhadap hasil belajar ranah kognitif siswa pada materi Hukum Newton. Jenis penelitian ini adalah penelitian pre eksprimental dengan rancangan <em>One Group Pretest Posttest Design</em>. Populasi penelitian ini adalah seluruh siswa kelas VIII MTs Makarim Al-akhlak Kota Singkawang. Dikarenakan kelas VIII hanya terdiri atas satu kelas, maka teknik <em>sampling</em> yang digunakan adalah <em>sampling</em> jenuh. Instrumen penelitian yang digunakan berupa tes pilihan ganda. Data dianalisis dengan menggunakan uji <em>paired t-test</em>. Dari hasil perhitungan diperoleh nilai –t<sub>hitung</sub> &lt; -t<sub>tabel</sub> yaitu -18,03 &lt; -2,160, maka H<sub>0</sub> ditolak dan H<sub>a</sub> diterima pada taraf signifikansi α = 0,05. Sehingga dapat disimpulkan bahwa terdapat pengaruh model <em>generative learning</em> terhadap hasil belajar ranah kognitif siswa pada materi Hukum Newton.</jats:p
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

PENENTUAN PERCEPATAN GRAVITASI PADA PERCOBAAN GERAK JATUH BEBAS DENGAN MEMANFAATKAN RANGKAIAN RELAI
Get PDFThe determination of the gravity acceleration through free fall experiment using the relay circuit has been done. This study aims to make free-fall experiment design using relay circuit, and determine the value of gravity acceleration by using this experiment design. The measurement method used in this study is to measure the free fall time of the object using a stopwatch that can work automatically. The result of this research is this experiment design can be used to get the free fall time data automatically. The values of gravity acceleration to 10 cm, 20 cm, 30 cm, 40 cm and 50 cm respectively, are 9.80952381 m/s2, 9.814058957 m/s2, 9.845 m/s2, 9.858283385 m/s2, and 9.829645226 m/s2. So that the average acceleration value of the five variations of height is 9.831302275 m/s2.
