Meningkatkan Kemampuan Berpikir Kritis melalui Alat Peraga Pilogma pada Materi Logika Matematika

Abstract

1,2,3 Universitas Maritim Raja Ali Haji 2018Abstrak Tujuan penelitian ini adalah untuk mengetahui bagaimana peningkatan kemampuan berpikir kritis siswa dengan menggunakan alat peraga Pilogma pada materi nilai kebenaran pernyataan majemuk Logika Matematika. Penelitian ini merupakan Penelitian Tindakan Kelas (PTK). Penelitian jenis kualitatif ini dilaksanakan dalam 2 siklus dan setiap siklus diadakan 2 kali pertemuan. Peneliti menggunakan teknik observasi, dokumentasi, wawancara, dan tes untuk memperoleh data. Teknik analisis data melalui tahap reduksi data, penyajian data dan penarikan kesimpulan dan verifikasi serta triangulasi data. Subjek penelitiannya adalah kelas X SMA Muhammadiyah Tanjungpinang. Objek penelitian yaitu meningkatkan kemampuan berpikir kritis siswa yang dilihat melalui hasil tes setiap akhir siklus I dan II serta hasil observasi, dokumentasi dan wawancara. Hasil penelitian menunjukkan bahwa kemampuan berpikir kritis siswa dapat ditingkatkan melalui penggunaan alat peraga Pilogma dalam pembelajaran materi Logika Matematika. Kata kunci: logika matematika, kemampuan berpikir kritis, alat peraga Pilogma AbstractThe purpose of this study is to find out how to improve students' critical thinking skills by using props Pilogma on the material of truth value of compound logic mathematical statements. This research is a Classroom Action Research. This qualitative research was conducted by using 2 cycles and each cycle contained 2 class meetings. Researchers used observation techniques, documentation, interviews, and tests to obtain data. Data analysis techniques through the data reduction phase, data presentation and conclusion drawing and verification and triangulation of data. The subject of this research is class X of SMA Muhammadiyah Tanjungpinang. The object of research is to improve students' critical thinking ability which can be seen through test result at the end of cycle I and II and observation, documentation and interview. The results showed that students' critical thinking ability can be improved through the use of props Pilogma in learning Mathematics Logic material.

Model Pembelajaran Probing Prompting Menggunakan Papan Mamiku Pada Materi SPLDV Terhadap Kemampuan Berpikir Kritis Matematis Siswa

“…Dalam langkah pertama dengan menunjukan pada siswa suatu keadaan yang baru, pada penelitian ini keadaan baru yang digunakan adalah alat peraga yakni papan mamiku(magnet miniatur kulkas). Alat peraga dalam kegiatan pembelajaran digunakan oleh siswa untuk dilihat, diamati dan dikaitkan dengan bahasan yang tengah dipelajari, dengan demikian siswa tidak menghafal konsep melainkan ikut terlibat langsung dan mengembangkan kemampuan berpikir kritinsnya melalui proses berpikir (Alawiah et al, 2018).Alat peraga papan mamiku adalah sebuah alat peraga yang dibuat menggunakan seng lurus tanpa gelombang yang dibingkai dengan kayu dan dilapisi cat atau skorlet berwarna putih sehingga bentuknya menyerupai papan tulis dengan ukuran yang lebih kecil. Dikatakan papan magnet miniatur kulkas karena nantinya saat pembelajaran papan tersebut akan ditempeli magnet miniatur kulkas sebagai bahan ajar agar pembelajaran lebih menarik bagi siswa.…”

Efektivitas Model Pembelajaran Group Investigation (GI) dan Teams Games Tournament (TGT) Ditinjau dari Kemampuan Berpikir Kritis Matematika

“…Dimana peserta didik diharapkan mampu menyatakan, menjelaskan, mendengar, menanyakan, menggambarkan, dan berkerjasama sehingga dapat memberi pemahaman pada peserta didik yang mendalam tentang Matematika. Dalam pembelajaran Matematika, komunikasi Matematis memiliki tujuan dalam mengembangkan kemampuan peserta didiknya, yaitu kemampuan mengekspresikan ide-ide Matematis secara lisan, tertulis, dapat mendemonstrasikan serta menjelaskan atau menggambarkan secara visual, kemampuan dalam memahami, menginterprentasikan dan evaluasi ide-ide Matematika baik secara lisan maupun dalam bentuk lainnya, dan kemampuan menggunakan notasi-notasi Matematika, istilah-istilah, dan struktur-strukturnya untuk menyajikan sebuah ide (Alawiah et al, 2018;Dina Indriyani et al, 2019;Sidiq & Prasetyo, 2020).…”

TBLA Mastery of Mathematical Concepts Through TPS (Think Pair Share) Learning Model Aided by Conversion Tool Games

“…The advantage of this tool is that students will be more active, not burdened with the material being studied and are game-oriented. Other advantages are: (1) the concept will be easy to understand and embedded in students so that it will always be remembered for a long time, (2) this teaching aid is also easy to make yourself with materials that are found in many school and student home environments, (3) In addition, this teaching aid is given an attractive color to change the impression of students, if learning mathematics must be serious and focus on being more relaxed, effective and fun (Alawiah et al, 2018;Immawan & Alimuddin, 2017). In line with this, (Setyowati et al, 2016) that learning media can stimulate students in learning including duplicating real objects, making abstract concepts into concrete concepts, and providing a learning atmosphere that is not depressed, relaxed and attractive so that it can achieve learning objectives, namely understanding the concept of conversion in mathematics learning.Several relevant previous studies can be used to determine the novelty of this research with other research, such as: (1) research conducted by experts who obtained the results that the application of the Think Pair Share (TPS) learning model can improve mathematical comprehension skills, (2) research that done by experts (Setyowati et al, 2016) who get the results that by using teaching aids students become easier to understand the material and finally the learning outcomes obtained increase, (3) research conducted by experts (Suhartini, 2015) who obtained the results that the use of TPS learning model assisted by serial images can improve the skills of writing one-act drama scripts for students.…”
