The test is a tool to collect information about the achievement of learning objectives so that the test must have good quality in order to be able to measure students' abilities accurately. To determine the quality of the test, it is necessary to do an analysis, one of which is the Rasch model approach. This study aims to analyze the quality of the final semester test results in learning mathematics—sampling using a purposive sampling technique. The subjects of this study were 56 students of Junior High School (SMP) in Yogyakarta, consisting of 25 males and 31 females. The test instrument consists of 40 multiple choice questions with the correct answer given a score of 1 and the wrong answer being given a score of 0. Therefore, the data obtained is dichotomous. The test kits were analyzed by applying the Rasch model. The study results obtained an estimate of the validity of item fit, where the questions analyzed had an INFIT MNSQ value between 0.94 - 1.11 and all questions with an OUTFIT value t ≤ 2.00; thus, 40 items fit according to the Rasch model. The characteristics of the test questions based on the Rasch model have a very difficult difficulty level of 0 items by 0%. The difficult category is three items at 7,5%, the medium category is 20 items at 50%, the easy category is 17 items at 42.5%, and 0% for the very easy category. The reliability of the case estimate value is 0.00 in the medium category, and the reliability of the item estimate value is 0.85 in the very high category. The implication of this research is additional knowledge regarding the Rasch analysis of mathematical problem models as a graduation standard.

Kesulitan yang dialami siswa dalam mempelajari kelarutan dan hasil kali kelarutan, masih banyak siswa belum memahami konsep prasyarat, seperti konsep mol, reaksi ionisasi, kesetimbangan kimia, pH larutan asam dan basa. Kesulitan siswa juga dikarenakan kurangnya guru memberikan contoh-contoh tentang reaksi-reaksi yang ada di lingkungan sekitar yang sering dijumpai siswa Penelitian ini bertujuan menganalisis efekktifitas media demonstrasi dan eksperimen berbasis animasi dalam meningkatkan keterampilan pemecahan masalah siswa di era revolusi industri 4.0. Jenis penelitian menggunakan Quasi Eksperimen dengan Nonequivalent Pretest Posttest Control Group Design. Subjek penelitian ini adalah 50 siswa kelas XI MIPA yang dibagi menjadi 27 siswa pada kelas eksperimen dan 24 siswa pada kelas control. Data dikumpulkan menggunakan metode tes. Teknik analisiss data menggunakan analisis kuantitatif. Hasil penelitian menunjukkan uji prasyarat normalitas dan homogenitas diperoleh nilai signifikansi > 0,05. Hasil uji paired sample t-test diperoleh Sig. 0,00 < 0,05 menunjukan pretest dan posttest kelas eksperimen maupun kelas kontrol berbeda signifikan. Hasil uji Independent sample t-test diperoleh Sig. (2-tailed) 0,018 < 0,05 sehingga ada perbedaan rata-rata antara kelas eksperimen dan kelas kontrol untuk meningkatkan keterampilan siswa dalam memecahkan masalah. Perbedaan rata-rata kelas eksperimen > rata-rata kelas kontrol yaitu 80 > 70. Itu berarti bahwa media demonstrasi dan eksperimen berbasis video animasi efektif digunakan pada proses pembelajaran.

Education in the 21st century is learning to prepare a generation that prioritizes advances in information and communication technology (ICT) as a medium for students to develop products in the form of animated videos, demonstrations and experiments. This study aims to produce valid, interesting, and effective learning media. This research is an ADDIE development research with five stages: analysis, design, development, implementation, and evaluation. The subjects in this study were three high school students with 60 students and three teachers and two validators—data collection instruments in questionnaires and tests. The data analysis technique in this research and development is a descriptive statistical analysis technique of percentages to process data from the validator's assessment, student responses and test results. Qualitative descriptive describes data in the form of suggestions and comments from the validator. The animation video media validation results obtained an average score of material expert validation, and media expert validation obtained a percentage of 84%, classified as very good. The results of the student response questionnaire to the learning media obtained a percentage of 86% with an exciting category. Finally, the test results obtained 100% results with effective criteria where all students met the minimum standard of completeness set by the school, namely 76 for chemistry subjects.

This study was conducted to analyze the test instrument used to measure the ability of students in the odd final exam in mathematics. Sampling using purposive sampling technique. These students consist of 398 students. The questions given are in the form of multiple-choice questions with a total of 40 items. The data analysis technique used quantitative descriptive analysis. Data analysis was carried out using the Item Response Theory (IRT) Rasch model approach with the help of QUEST software. The results of the analysis show, from 40 items there are 39 items fit with the Rasch model. Judging from the level of difficulty, items with very difficult categories are 0%, difficult categories are 8 items or 21%, moderate item categories are 23 items or 59%, easy categories are 8 items or 21%, and very easy categories are 0 %. The reliability of the estimatedvalue of the item is 0.95 with a very good category so that it affects the items that fit the model. Thehigher reliability, the more items that fit the model. The reliability of the case estimate value is 0.00with a weak category. This value indicates an inconsistency in the answers of the test takers, whichmeans that the test takers are careless in answering the questions, thus affecting the reliability ofthe questions.

Kemampuan literasi sains sangat diperlukan di era globalisasi melalui sains dan teknologi. Sains dan teknologi khususnya memiliki peran yang sangat besar dalam meningkatkan mutu pendidikan. Tujuan penelitian ini menyajikan bibliometrik dan bibliografis dari berbagai literatur mengenai literasi sins. Analisis bibliometrik menggunakan VOSviewer yang terdapat 989 literatur dari database google scholar yang diterbitkan dari tahun 2018-2023. Analisis tren publikasi dan kutipan dari tahun 2018-2023 untuk melihat perkembangan publikasi sedikit meningkat dari tahun 2018-2022 terkait Literasi Sains berdasarkan terindeks Google Scholar. Namun menagalami penurunan pada tahun 2023. Publikasi terbanyak dilakukan pada tahun 2022 sebanyak 265 artikel. Disisi lain, kutipan pada artikel mengalami pengingkatan pada tahun 2018-2022. Kutipan terbanyak pada tahun 2018 sebanyak 209 kutipan dan kutipan terendah pada tahun 2023 dengan 13 kutipan. Kajian ini memberikan informasi bagi para peneliti pendidikan literasi sains dalam pelaksanaan pembelajaran sepertinya belum banyak dilakukan yang diharapkan dapat menguatkan topik peneliti selanjutnya.

Pembelajaran selama pandemic hanya dilakukan dengan daring, sehingga ini menjadi tantangan SMA Taruna Nusantara dalam proses melaksanakan pendididkan karakter. Disisi lain pendidikan karakter yang diterapkan secara daring akan memberikan kesempatan bagi peserta didik dalam mengaktualisasukan nilai-nilai pendidikan karakter di lingkungan keluarga dan masyarakat dalam upaya keikutsertaan pencegahan dan penanggulangan pandemic covid-19 dengan memberi contoh pola hidup sehat dan peserta didik dapat menjadi contoh duta protokol kesehatan dilingkungan tempat tinggal siswa pada situasi pandemi. Penelitian ini bertujuan untuk mendeskripsikan penerapan pendidikan karakter bagi siswa saat melakukan pembelajaran secara daring di tengah kondisi pandemi Covid-19. Peneliti menggunakan pendekatan kualitatif dengan jenis penelitian studi kasus dan bersifat deskriptif. Teknik pengumpulan data yang digunakan adalah observasi, wawancara, dokumentasi. Keseluruhan data yang terkumpul akan dianalisis secara kualitatif. Hasil Penelitian menyimpulkan bahwa pembelajaran daring dimasa pandemic covid-19 memang perlu kreatifitas, apalagi jika berkaitan dengan pendidikan karakter perlu adanya sinergi antara pamong-siswa-orangtua supaya pendidikan karakter tercapai, sehingga dapat menjadi bekal untuk siswa dalam menapaki cita-cita dan masa depan. Kesuksesan seseorang tidak hanya ditentukan seberapa tinggi pendidikan dan nilai akademik yang dicapai, tetapi kesuksesan seseorang ditentukan juga oleh karakter (attitude) yang baik.
