Abstract

The purpose of this study was to determine the differences in students' mathematical abilities using the WhatsApp group and classroom platforms during the Covid-19 pandemic in class VIII of SMP Negeri 2 Hinai. This research method is to use quasi-experimental research. The number of samples in this study were 60 students divided into 2 class groups, namely the experimental class 1 which was taught using WhatsApp group, and the experimental class 2 which was taught using classroom. The data collection instruments were in the form of tests of students' mathematical understanding abilities before and after being given treatment (pretest and posttest). Based on the results of hypothesis testing with the t test technique, the value of t count> t table is 2.16> 2.04 so it can be concluded that there are differences in students' mathematical abilities using the WhatsApp group platform and classrooms during the Covid-19 pandemic in class VIII SMP. Negeri 2 Hinai. Students 'mathematical abilities using the WhatsApp group platform are superior to students' mathematical abilities using classroom.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan pembelajaran bangun datar dengan menggunakan media puzzle pada tingkat sekolah dasar. Penelitian ini menggunakan jenis penelitian field research atau survey di lapangan, yang dilaksanakan secara langsung dan menjalankan penelitian untuk mengetahui apa yang sebenarnya terjadi dengan berbagai masalah serta memiliki subjek penelitian yaitu 10 anak pada tingkat sekolah dasar kelas 3- 5. Hasil penelitian menunjukkan bahwa media puzzle terbukti dapat meningkatkan aktivitas dan hasil belajar siswa, serta performansi guru. Media Puzzle sangat bermanfaat untuk pembelajaran apa saja, termasuk pembelajaran matematika yang dengan mudah anak-anak dapat memahaminya. This study aims to describe the learning of flat shapes using puzzle media at the elementary school level. This research uses field research or survey research in the field, which is carried out directly and conducts research to find out what is really going on with various problems and has research subjects, namely 10 children at the elementary school level grades 3-5. The results showed that puzzle media was proven to be able to increase student activity and learning outcomes, as well as teacher performance. Media Puzzle is very useful for any learning, including learning mathematics which children can easily understand.

Abstract

Penelitian ini bertujuan untuk mengetahui apakah model pembelajaran Think Pair Share (TPS) terdapat pengaruh yang signifikan terhadap kemampuan pemahaman konsep siswa. Penelitian ini dilaksanakan di SMA Negeri 11 Medan Tahun Pelajaran 2021-2022. Penelitian ini merupakan penelitian eksperimen semu, dengan desain penelitian  pretest and posttest control group design. Pengambilan sampel dilakukan secara acak dan sederhana (simple random sampling). Sampel penelitian ini adalah 72 siswa terdiri atas siswa kelas XI-A 1 sebagai kelas eksperimen dengan 36 siswa dan siswa kelas XI-A 2 sebagai  kelas kontrol dengan 36 siswa. Instrumen penelitian yang diberikan berupa tes yang terdiri dari 5 soal uraian. Uji prasyarat yang digunakan adalah uji Liliefors untuk menguji normalitas data, sedangkan uji Fisher untuk menguji homogenitas data. Berdasarkan hasil uji normalitas diperoleh bahwa kedua populasi berditribusi normal. Sedangkan hasil uji homogenitas diperoleh bahwa kedua populasi homogen (sama). Teknik analisis data menggunakan uji regresi linier sederhana. Berdasarkan hasil penelitian, nilai rata-rata pretest kelas eksperimen 48,03 dan nilai rata-rata pretest kelas kontrol 46,33. Sedangkan nilai rata-rata posttest kelas eksperimen 54,78 dan nilai rata-rata posttest kelas kontrol 50,47. Terdapat pengaruh yang signifikan antara pembelajaran TPS terhadap kemampuan pemahaman konsep siswa yang dapat dilihat dari hasil perhitungan uji regresi linier sederhana diperoleh rtabel = 0,329, sementara berdasarkan perhitungan yang telah dilakukan diperoleh rhitung = 0,71. Dari perhitungan terlihat bahwa rhitung > rtabel (0,71 > 0,329).

Abstract

This development research aims to find out; (a) Validity of LKPD assisted by the Canva application on circle material based on ethnomathematics to improve students' mathematical communication skills, (b) Practicality of LKPD assisted by the Canva application on circle material based on ethnomathematics to improve students' mathematical communication skills and (c) Effectiveness of LKPD assisted by the Canva application on material Ethnomathematics-Based Circles to Improve Students' Mathematical Communication Skills. The type of research used is Research and Development (RnD). The research model used is the 4D Model (Define, Design, Development and Disseminate). The subjects in this research were 30 class VIII students at MTs Muhammadiyah Sidomulyo. The results of this research analysis are; (a) The LKPD developed meets the valid category and the percentage value obtained is 94.25% with the criteria "Very Appropriate" (b) The LKPD developed meets the practical category and the percentage value obtained is 93.33% with the criteria "Very Good" (3) The LKPD that was developed met the effective category with a complete learning result obtained by a percentage of 86.66% and students who completed the minimum KKM score, namely 27 students with classical completeness obtained a percentage of 90%. This shows that overall, the development of LKPD assisted by the Canva application on ethnomathematics-based circle material to improve the mathematical communication skills of class VIII students at MTs Muhammadiyah Sidomulyo is included in the valid, practical and effective category.

Penelitian inimenggunakan pendekatan kuantitatif dengan desain eksperimensemu (quasi experiment) model Pretest-Posttest Control GroupDesign. Subjek penelitian adalah 60 siswa kelas IV SD Negeri060821 Medan, terdiri dari kelas eksperimen (30 siswa) dan kelaskontrol (30 siswa). Instrumen penelitian berupa tes hasil belajarberbentuk pilihan ganda 25 butir dengan reliabilitas CronbachAlpha sebesar 0,87. Analisis data menggunakan uji-t independendengan bantuan SPSS 26. Hasil penelitian menunjukkan adanyaperbedaan signifikan antara hasil belajar siswa kelas eksperimendan kontrol (t_hitung = 4,73 > t_tabel = 2,00; p < 0,05). Nilai rata-rata posttest kelas eksperimen (86,27) lebih tinggi dibanding kelaskontrol (77,13). Dengan demikian, penerapan pembelajarantematik berbasis masalah efektif meningkatkan hasil belajar siswasekolah dasar di Kota Medan.
