Abstract

Penelitian ini bertujuan untuk menjelaskan pendekatan Contextual Teaching and Learning (CTL) yang diterapkan dalam pembelajaran matematika dengan menggunakan studi literatur. Sumber data dalam penelitian ini ditempuh melalui riset kepustakaan murni berupa data sekunder dengan mengkaji sumber-sumber tertulis seperti jurnal-jurnal ilmiah. Teknik analisis data dalam penelitian ini melalui beberapa tahap, yaitu meringkas data, menarik berbagai topik pembahasan, mengembangkan data berdasarkan kepentingannya, melakukan cross check, memaparkan hasil yang telah dihimpun dan menarik kesimpulan. Hasil penelitian menunjukkan bahwa pendekatan Contextual Teaching and Learning (CTL) pada tahapan pembelajaran memiliki relevansi dengan indikator kemampuan berpikir kritis matematis, yaitu mampu menganalisis, merumuskan pokok permasalahan, menentukan strategi, memeriksa kembali dan menyimpulkan masalah yang diberikan. Selain itu jika dikaitkan dengan kategori PAM, kategori siswa berkemampuan tinggi memberikan kontribusi peningkatan kemampuan berpikir kritis matematis lebih tinggi bila dibandingkan dengan kategori siswa kemampuan sedang maupun siswa kemampuan rendah. Selanjutnya jika dikaitkan dengan tingkat pendidikan, kemampuan berpikir kritis matematis siswa SMP dan SMA melalui pendekatan CTL mengalami peningkatan kemampuan berpikir kritis matematis yang cukup baik. Sehingga dapat disimpulkan bahwa pendekatan CTL mampu meningkatkan kemampuan berpikir kritis matematis saat diterapkan dalam pembelajaran matematika

Abstract

Research on this observation was conducted to see how effective the use of teaching aids to improve student activity and learning outcomes in mathematics learning. The learning activity referred to here is how students can involve all psychophysical aspects, both physical and spiritual so that the acceleration of changes in their behavior can occur quickly, precisely, easily, and correctly, both related to cognitive, affective, and psychomotor aspects. The type of research used is Class Action Research (PTK). Observation was carried out as many as 2 cycles by giving essay questions as many as 5 numbers, with each cycle consisting of 2x30 minutes In general, each cycle starts from the stage of action planning, action execution, observation, and also reflection. Based on the results of this study, it shows that before using props, namely in cycle 1, student results were completed with an average percentage of 68.3% with KKM 78, while in cycle 2, props have been applied so that they were obtained with a completeness of 90.5% so that they experienced an increase of 22.2% with a moderate category in cycle 1 to a high category after being implemented in cycle 2. From these results, it can be seen that teaching aids are able to improve student learning outcomes which previously in cycle 1 student results had not reached the KKM score and after applying props in cycle 2 were able to improve student abilities effectively. The conclusion of the observations in this study is that the effectiveness of using teaching aids can improve student learning outcomes.
