Abstract

This study focuses on developing the new level of scientific argumentation skills and new items that are feasible and valid for used. There are 195 science students at Islamic State School 1 (MAN 1) Yogyakarta as participant in this study. Random sampling technique was used from the three schools of Islamis State School (MAN) in Yogyakarta, Indonesia. There are seven experts (3 Professor, 2 teachers, and 2 graduate students) reviewed 14 items for the first phase of this study. For the second phase, 98 students answered 14 questions which each questions contain five point (claim, data, backing, warrant and rebuttal). For the third phase, after choosed the best five 5 questions, We asked the others (97 students) to answer those questions. The modification of the level of scientific argumentation skills indicates the ability of students is still low. At level 1 (claims) there were only 38.9% students, level 2 (data) were 21.6% students, level 3 (warrants) 16.6% students, level 4 (backing) 16.2% while level 5 (rebuttal) is the most difficult, for students’ users only by 4.2%. Based on the findings, the test can measure and show with a separate level of students' scientific argumentation skill in this school.

Abstract

Students in Indonesia still have the low level of scientific argumentation skills. This studypurposed to examine the impact ofProblem-based Learning (PBL) with Argument Mapping and Online Laboratory in improving the scientific argumentation skill. It describes the significance of the differences between participants who learn through PBL, PBL with Online Laboratory (PBL-OL), Problem-based Learning with Argument Mapping and Online Laboratory (PBL-AMOL) model. The population of this study were students from Madrasah Aliyah Negeri (MAN) Yogyakarta, Indonesia with a random sampling technique. This was quasi-experiment with pre and post test designs. In this study, there were 97 students at MAN 1 as respondent. Paired sample t-test, independent sample t-test and ANOVA mixed design was used to analysis data. The PBL-AMOL group has a significant difference based on pre-test and post-test (sig. 0000). The PBL-AMOL was most effective to improve the skill with gain score 0.43 (medium). Learning with the PBL-AMOL model can be an alternative to solve the problems of creative thinking skill.

Abstract

Terdapat banyak model pembelajaran yang diterapkan untuk menganalisis kemampuan argumentasi ilmiah siswa. Namun, belum banyak model yang diintegrasikan dengan pembelajaran berbasis simulasi online untuk meningkatkan kemampuan argumentasi ilmiah siswa. Padahal, saat ini ada banyak website simulasi online yang diterbitkan oleh lembaga pendidikan atau universitas di tingkat internasional dan jarang digunakan dalam penelitian. Penelitian ini mengintegrasikan model pembelajaran inovatif dengan pembelajaran berbasis online simulation untuk meningkatkan kemampuan argumentasi ilmiah siswa. Website simulasi yang digunakan adalah Edu-media simulation. Dalam website ini ada banyak simulasi fisika yang disediakan, tetapi belum banyak penelitian yang menerapkan simulasi ini. Penelitian ini dilakukan dengan kuasi eksperimen yang terdiri dari satu kelas eksperimen dengan sampel 25 siswa kelas XI MIA 3 di SMA N 1 Prambanan Yogyakarta. Argumentasi ilmiah siswa diukur melalui instrumen tes uraian. Data argumentasi ilmiah siswa dianalisis menggunakan paired sample t-test  dan pola argumentasi Toulmin (TAP). Hasil penelitian menunjukkan bahwa PBL berbantuan edu-media simulation dapat meningkatkan kemampuan argumentasi ilmiah siswa baik secara kuantitatif maupun kualitatif. Ini ditunjukkan dengan nilai t value -11.051 -1.711 bahwa terdapat perbedaan nilai rata-rata argumentasi pada pre-test (17) dan post-test (47). Dalam hal ini, siswa sudah mampu membuat klaim yang tegas dengan menyajikan bukti dan alasan yang mendukung klaim. Analyzing students’ scientific argumentation skill in optic: Problem-based learning assisted edu-media simulation AbstractThere are many learning models applied to analyze the ability of students' scientific argumentation. However, not many models have been integrated with online simulation-based learning to improve students' scientific argumentation skills. In fact, there are currently many online simulation websites published by educational institutions or international universities and rarely used in research. This research integrates innovative learning models with online simulation-based learning to improve students' scientific argumentation skills. The simulation website used is Edu-media simulation. In this website there are many physics simulations provided, but not many studies have applied this simulation. This research was conducted with a quasi-experimental consisting of one experimental class with a sample of 25 XI MIA 3 graders in Prambanan High School 1 Yogyakarta. Students' scientific arguments are measured through a description test instrument. Students' scientific argumentation data were analyzed using paired sample t-test and Toulmin argumentation patterns (TAP). The results showed that PBL assisted by edu-media simulation can improve students' scientific argumentation ability both quantitatively and qualitatively. This is indicated by the value of t value -11.051 -1.711 that there are differences in the average value of argumentation in the pre-test (17) and post-test (47). In this case, students have been able to make assertive claims by presenting evidence and reasons that support the claim.

Abstract

Abstract: Many types of fiber optics have been developed and used by researchers to create best fiber. This study aimed to provide an overview of the the type of fiber optics based on the number of mode and refractive index. Also the study provide a breif comparison of these types with their strengths and weakness. A total 30 article published (from the year 2016 to 2020) in main journals wew investigated thoroughly through document analysis method. The study reveals some type of fiber optic. However, each types has some advantages as well as disadvantages over the others that should be kept in mind in their usages. A carefull user, such as researcher or others would be aware of the types and select the most effective one for his/her purposes.Keywords: Fiber optics, number of mode, refractive indexAbstrak: Banyak jenis fiber optik telah dikembangkan dan digunakan oleh para peneliti untuk menghasilkan jenis terbaik. Penelitian ini bertujuan untuk memberikan gambaran tentang jenis fiber optik berdasarkan jumlah mode dan indeks biasnya. Studi ini juga memberikan perbandingan singkat dari jenis-jenis ini dengan kelebihan dan kekurangannya. Sebanyak 30 artikel yang diterbitkan (dari tahun 2016 hingga 2020) di jurnal-jurnal utama yang telah diteliti secara menyeluruh melalui metode analisis dokumen. Studi ini mengungkapkan kelbihan dan kekurangan setiap jenis fiber optik. Namun, masing-masing jenis memiliki beberapa kelebihan dan kekurangan dibandingkan yang lain yang harus diingat dalam penggunaannya. Pengguna yang berhati-hati, seperti peneliti atau orang lain akan menyadari jenisnya dan memilih yang paling efektif sesuai dengan tujuan penggunaan.Kata-kata kunci: Fiber optic, jumlah mode, dan indeks bias

Abstract

Statistical literacy is fundamental competence to think critically and to conclude information based on data. This study aims to describe students’ statistical literacy according to gender, grade, and educational field. This research was a quantitative method with a cross-sectional design by explaining and analyzing the results using Rasch modeling, and students’ statistical literacy was categorized and described according to statistical literacy topics, gender, student grade level, and educational field. The respondent of this study was 271 students obtained through the stratified random sampling in Yogyakarta’s senior high school. The result of this study confirmed that the statistical literacy skills of students are still at a low level. The lowest aspect is the scope of conclusions, while the highest aspect is data production (medium level). There are no significant differences in statistical literacy skills based on gender and class. However, there are significant differences in statistical literacy based on field education. It indicates that policymakers or teachers should improve students’ statistical literacy skills by training or applying a learning model that focuses explicitly on statistical literacy skills.
