Abstract

Penelitian ini bertujuan untuk mengetahui apakah pembelajaran berbasis Edmodo dapat meningkatkan pemecahan masalah matematis siswa di kelas X SMA Negeri 1 Manduamas. Penelitian ini dilaksanakan di kelas X SMA Negeri 1 Manduamas. Metode penelitian yang digunakan adalah metode eksperimen. Populasi dalam penelitian ini berjumlah 108 siswa. Sampel dalam penelitian ini ditentukan dengan cluster simple random sampling yaitu kelas X-IPA1 yang berjumlah 21 orang. Teknik pengumpulan data yang digunakan adalah observasi dan tes. Data yang dikumpulkan dianalisis dengan analisis deskriptif dan analisis inferensial. Berdasarkan hasil observasi gambaran pembelajaran berbasis edmodo diperoleh nilai rata-rata sebesar 3,00. Berdasarkan hasil penelitian diketahui gambaran kemampuan pemecahan masalah matematis siswa sebelum pembelajaran berbasis edmodo diperoleh berada pada kategori cukup dengan nilai rata-rata sebesar 64,48. Kemudian gambaran kemampuan pemecahan masalah matematis siswa setelah pembelajaran berbasis edmodo diperoleh nilai rata-rata sebesar 81,33 dengan kategori baik. Berdasarkan hasil uji hipotesis yang dilakukan diketahui 0.000 < 0.005 artinya “Terdapat peningkatan pemecahan masalah matematis ditinjau dari pembelajaran berbasis edmodo pada siswa kelas X IPA-1 SMA Negeri 1 Manduamas”. Kemudian ketuntasan klasikal sebesar 61.90% perolehan persentase tersebut berada pada kategori efektif. Adapun nilai N-Gain sebesar 0.54 berada pada klasifikasi sedang.

Abstract

Learning devices are part of supporting the learning atmosphere in order to achieve the desired goals. Without the support of good learning tools, it is very difficult to create effective learning. To ensure the implementation of good learning, learning tools are needed that meet various aspects, one of which is the validity of learning tools. This study aims to describe the level of validity of the Numbered Head Together (NHT) cooperative learning device in teaching students' critical thinking skills in mathematics. This type of research is a quantitative descriptive research. The subject of the research is a learning device which includes lesson plans and student activity sheet (SAS) on the material of Relations and Functions for students of SMP/MTs class VIII. The object of research is the level of validity of the learning device. The instrument used is a learning device validation sheet which includes a lesson plan validation sheet and a SAS validation sheet. Data was collected through filling out the learning device validation sheet from five validators to get assessments and suggestions for learning tools. The results of the analysis of the validation sheet show that in general the RPP meets the valid criteria with a validity index of 0.74 and the SAS also meets the valid criteria with a validity index of 0.73. Thus, it is concluded that cooperative learning tools in teaching students' critical thinking skills in mathematics are valid.

Abstract

This article discusses supporting applications for learning mathematics during the Covid-19 pandemic. The corona virus or Covid-19 is currently sweeping the world, including Indonesia, participating in influencing the world of education where the teaching and learning process is usually carried out face-to-face in classrooms due to the Covid-19 pandemic, the teaching and learning process must be done through distance learning (online ). Technology-based learning media that is commonly used are computers. To support computers, we need software in the form of applications. With the application, it is hoped that teachers and students will be more optimal in carrying out teaching and learning activities online. An important application to support mathematics learning is because mathematics is abstract and is often considered difficult by students. Some of these applications are Geogebra, Matlab, Wingeom, Microsoft Math 3.0 and Microsoft Math 4.0. This study aims to assist teachers and students in using applications that support mathematics learning.
