Penelitian ini bertujuan untuk mengembangkan media pembelajaran kimia berupa modul elektornik berbasis pendekatan saintifik pada materi tata nama senyawa dan persamaan reaksi kimia kelas X. Metode penelitian yang digunakan adalah penelitian dan pengembangan (Research and Development) dengan model penelitian ADDIE yang meliputi tahap analisis (Analyze), tahap perancangan produk (Design), pengembangan produk (Develop), implementasi produk (Implement), dan evaluasi akhir pada produk (Evaluate). Rancangan kegiatan pembelajaran pada modul elektronik disusun secara sistematis dan menerapkan langkah-langkah pendekatan saintifik. Hasil validasi oleh ahli materi, ahli bahasa, dan ahli media menunjukkan hasil sangat baik, yaitu dengan nilai r sebesar 0,67; 0,72; dan 0,67. Pada tahap akhir, hasil uji coba produk oleh peserta didik dan guru juga menunjukkan hasil yang sangat baik dengan rata-rata presentase skor 90,3% dan 95,4%. Berdasarkan hasil yang diperoleh, dapat disimpulkan bahwa modul pembelajaran berbasis pendekatan saintifik pada materi tata nama senyawa dan persamaan reaksi kimia yang dikembangkan memperoleh interpretasi sangat baik dan layak untuk digunakan dalam kegiatan pembelajaran kimia.

ANALYSIS OF TEST ITEMS ANALYSIS OF TEST ITEMS OF FINAL EXAMINATION OF THE SECOND SEMESTERS ON CHEMISTRY SUBJECT OF XI NATURAL SCIENCE AT STATE SENIOR HIGH SCHOOL 6 PEKANBARU IN ACADEMIC YEAR OF 2015/2016

There were many factors causing problems encountered in the learning process, one of them was the learning instrument used and created by the teacher. Learning instrument can be as test items. This research aimed at knowing the quality of test items of final examination of the second semester on Chemistry subject of XI Natural Science at State Senior High School 6 Pekanbaru in the Academic Year of 2015/2016 in terms of qualitative and quantitative aspects. Sample of this research was all student answer sheets of XI Natural Science (XI Natural Science 1 to 6) comprised 192 students. Test items of final examination of the second semester comprised 30 multiple choice questions. Research findings showed inappropriate test items in term of qualitative aspect, there were 8 (26.7%) test items in term of material, 12 (40%) test items in term of construction, and 23 (76.6%) test items in term of language. Whereas in the quantitative aspect, 3 (10%) test items were not valid. High reliability test items were 0.72. In term of discriminator, there were 3 (10%) test items were on bad category, 11 (36.7%) test items were on medium category, and 16 (53.3%) test items were on good category. In term of difficulty level, there were 2 (6.9%) test items were on difficult category, 22 (72.4%) test items were on medium category, and 6 (23%) test items were on easy category. 27 (23%) options of distractors were not working. It could be concluded that the percentage of inappropriate test items in qualitative aspect was 47.7% meaning that the quality of test items was enough. In quantitative aspect validity, reliability, and discriminator were on good criteria, whereas difficulty level and distractor were on enough criterion.

Peningkatan HOTS pada Mata Pelajaran Green Chemistry Menggunakan Model Problem Based Learning

2024-08-16T22:01:28+07:00

High-Ordered Thinking Skills (HOTS) are skills that must be possessed by students in the 21st century. To obtain good HOTS, a HOTS-based learning model is needed. State Senior High School (SMAN) 2 Jonggol, West Java, is one of the schools that has implemented the Independent Curriculum since 2020. The Independent Curriculum requires HOTS-based learning such as Project Based Learning (PjBL), and Problem-Based Learning (PBL). This means that SMAN 2 Jonggol has implemented HOTS-based learning. However, based on the results of interviews with chemistry teachers, students' HOTS was still low, indicated by students who tended to be passive and had difficulty concluding learning material. Therefore, this study uses a problem-based learning model to analyze the increase in HOTS in green chemistry material. This study uses the Classroom Action research method. The sampling technique in this study was purposive sampling, with a total of 42 students. The results of the Wilcoxon test have a Positive Ranks value at N of 42. This explains that there is an increase in student HOTS after using the problem-based learning model. So, it can be concluded that the problem-based learning model affects increasing students' HOTS skills.

2024-08-16T22:43:34+07:00

Tujuan dari penelitian ini adalah untuk mengembangkan media pembelajaran dan menanggapi minat pengguna Web Google Sites materi sifat koligatif larutan. Menggunakan model pengembangan ADDIE (analisis, desain, pengembangan, implementasi dan evaluasi). Subjek penelitian yaitu lima peserta didik kelas Xll IPA pedoman angket dan wawancara berfungsi sebagai pengambilan data, menggunakan teknik analisis deskriptif kualitatif. Pada penelitian ini menunjukkan bahwa mengembangkan media Web Google Sites sampai pada tahap pengembangan. Media pembelajaran ini terdiri dari halaman utama, halaman KI-KD-IPK, halaman materi, halaman latihan soal, halaman games, halaman video pembelajaran, halaman evaluasi, halaman daftar isi, dan halaman about us. Dari hasil validasi yang didapat bahwa media ini mendapat kriteria “layak” dengan skor 83% dari ahli materi serta mendapat kriteria “sangat menarik” dengan skor 87% dari lima peserta didik. Dengan demikian media pembelajaran berbasis Web Google Sites dapat digunakan dalam pembelajaran.
