PENGEMBANGAN APLIKASI PERKALIAN DALAM MENINGKATKAN PEMAHAMAN KONSEP DASAR PERKALIAN SISWA SD

Pada hakikatnya perkalian merupakan oprasi penjumlahan yang dilakukan secara berulang yang sudah dipelajari dari kelas rendah, namun ternyata tidak sedikit peserta didik di kelas tinggi masih ada yang kurang lancer dalam mengoprasikan perkalian. Hal itu merupakan salah satu alasan dilakukan penelitian ini. Tujuan dari penelitian yang dilakukan ialah untuk mengetahui bagaimana kelayakan aplikasi perkalian yang dikembangkan, bagaimana respon peserta didik terhadap aplikasi perkalian yang dikembangkan, dan mengetahui apakah aplikasi perkalian dapat memberikan peningkatan pada siswa sekolah dasar dalam belajar perkalian. Penelitian ini menggunakan metode Research & Development (R&D). Analisis data yang digunakan ialah analisis deskriptif. Hasil menunjukan kemapuan pemahaman konsep peserta didik mengalami peningkatan setelah menggunakan aplikasi perkalian daam belajar dibuktikan dengan adanya hasil analisis tes dengan nilai gain-score, pada uji coba tahap 1 diperoleh kategori sedang yaitu sebesar 0,57 dan pada uji coba tahap 2 diperoleh 0,59. Berdasarkan hal tersebut dapat diartikan bahwa peserta didik setuju bahwa pembelajaran dengan menggunakan aplikasi perkalian dapat membantu dalam meningkatkan pemahaman konsep.

EFEKTIVITAS PEMBELAJARAN GEOMETRI MOLEKUL MENGGUNAKAN MOBILE VIRTUAL REALITY (MVR) UNTUK MENINGKATKAN KEMAMPUAN VISUOSPASIAL

Chemistry is a branch of science that encourages various advances in various fields. However, the characteristics of chemistry which have complex concepts make it difficult for class X high school students to understand chemistry. Thus, the problem that is the focus of discussion in this study is how to overcome the low visuospatial skills of high school students in class X, so that students can understand complex concepts in chemistry. This study uses the research design and development of the 4D Thiaganrajan modified 3D Ibrahim method. This study aims to determine the effectiveness of Mobile Virtual Reality (MVR)-based molecular geometry learning media in improving visuospatial skills. The effectiveness of the MVR-based molecular geometry learning media is stated based on the interpretation of the N-Gain score. The results showed an increase in the percentage of correct answers on the posttest by 32.15% with a significance level ranging from 0.57-1 in the medium to high category. In this regard, the use of MVR-based molecular geometry learning media is said to be effective because it can improve students' visuospatial skills. That is, MVR-based molecular geometry learning media can help students to comprehensively represent molecular geometry sub-materials.AbstrakKimia merupakan salah satu cabang ilmu pengetahuan yang mendorong berbagai kemajuan di berbagai bidang.

EFEKTIVITAS MODEL PEMBELAJARAN BLENDED LEARNING TERHADAP HASIL BELAJAR MAHASISWA DI MASA PANDEMI COVID 19

Blended Learning merupakan salah satu model pembelajaran yang memadukan pembelajaran tatap muka (konvensional) dan pembelajaran online. Metode penelitian yang digunakan adalah Pre-Experimental Designs dengan model One –Group Pretest- Postest Design, yang bertujuan untuk menilai perbedaan hasil belajar model pembelajaran blended learning dengan model pembelajaran tatap muka langsung (konvensional). Penelitian dilakukan pada mahasiswa Prodi Pendidikan Bahasa Inggris UIN Ar-raniry di semester Genap 2020/2021 yang berjumlah 30 orang yang dipilih dengan teknik purposive sampling. Pengumpulan data dilakukan dengan menggunakan instrumen tes, sedangkan teknik analisis data menggunakan uji prasyarat dan uji hipotesis. Berdasarkan penelitian diperoleh nilai t hitung sebesar 9,517 dan pada taraf signifikansi 0,05 diperoleh nilai t tabel sebesar 2,045 yang artinya t hitung > t tabel (9,517 > 2,045) maka Ho ditolak dan Ha diterima artinya terdapat perbedaan rata-rata antara hasil belajar Pretest dan Posttest yang berarti bahwa pembelajaran model blended learning memberikan efektivitas yang signifikan dan lebih baik dibandingkan dengan pembelajaran tatap muka (konvensional). Namun berdasarkan nilai rata-rata N-gain Score sebesar 29,90. atau 29,90% termasuk dalam kategori tidak efektif. Hal ini cukup dimaklumi mengingat berbagai kendala dan keterbatasan yang menyebabkan pembelajaran belum dapat dilaksanakan secara maksimal. Sehingga wajar sekali efektivitas model pembelajaran Blended learning dalam penelitian ini tidak efektif untuk meningkatkan hasil belajar.
