Abstract

Students' poor performance in mathematics is influenced by the teacher's incompetence in designing an engaging learning environment. This study's overarching goal is to enhance the mathematical knowledge of SMA Negeri 10 Medan's IPA 1 students in the eleventh grade by using the Problem Based Learning paradigm. This study uses Classroom Action Research (PTK), a research technique that has been used in two research cycles. The four phases of research in each cycle are preparation, execution, evaluation, and reflection. In this study, 36 students (16 males and 20 females) from class XI IPA 1 of SMA Negeri 10 Medan participated. In order to gather data, we used observation and a 5-question fill-out exam. Percentage computations were used in the data analysis method. The research results showed that student learning outcomes in cycle I averaged 71.94 with classical completion at 55.55%. Meanwhile, learning outcomes in cycle II averaged 82.22 with classical completeness of 83.33%. Results show that classical learning outcomes have improved, leading us to believe that PBL (Problem Based Learning) Learning Model may help students in Science 1 of class XI at SMA Negeri 10 Medan learn more mathematics.

Abstract

Abstrak Pemahaman konsep matematis yang baik tentu saja tidak hanya diperuntukkan bagi anak-anak yang berada di wilayah yang memiliki tingkat pendidikan tinggi saja melainkan juga wilayah yang memiliki tingkat pendidikan yang rendah seperti wilayah tepian Sungai Deli. Wilayah tersebut masih mempunyai tingkat pendidikan yang minim maka pemahaman konsep matematis yang ada di lingkungan itu masih tergolong rendah dan masih banyak anak-anak yang buta terhadap matematika dasar seperti operasi hitung matematika. Maksud analisis ini ialah untuk mengoptimalkan pemahaman konsep matematis anak-anak di SASUDE berbantuan pojok alat peraga matematik (POLAGATIK). Kegiatan ini dilakukan di Sanggar Sungai Deli, Kec. Medan Maimun, Kota Medan, Sumatera Utara. Peserta kegiatan ini merupakan anak-anak berumur 7-13 tahun. Kegiatan ini menggunakan metode pendidikan masyarakat dengan empat langkah utama: persiapan, pelaksanaan, pemantauan, dan penilaian. Hasilnya menunjukkan peningkatan pemahaman konsep matematika anak-anak dari Pre-test ke Post-test sebesar 72%. Kegiatan tersebut berjalan dengan lancar dan mendapat tanggapan positif dari peserta anak-anak Kata kunci: pemahaman konsep matematis; alat peraga; POLAGATIK; SASUDE. Abstract A good understanding of mathematical concepts is of course not only intended for children in areas with a high level of education but also in areas with a low level of education such as areas on the banks of the Deli River. This area still has a minimal level of education, so understanding of mathematical concepts in that environment is still relatively low and there are still many children who are blind to basic mathematics such as mathematical calculation operations. The purpose of this analysis is to optimize children's understanding of mathematical concepts at SASUDE with the help of the mathematics teaching aids corner (POLAGATIK). This activity was carried out at Sanggar Sungai Deli, Kec. Medan Maimun, Medan City, North Sumatra. Participants in this activity are children aged 7-13 years. This activity uses a community education method with four main steps: preparation, implementation, monitoring and assessment. The results show an increase in children's understanding of mathematical concepts from Pre-test to Post-test by 72%. This activity ran smoothly and received positive responses from the child participants. Keywords: understanding mathematical concepts; props; POLAGATIK; SASUDE
