PENINGKATAN HASIL BELAJAR OPERASI ALJABAR MELALUI STRATEGI PEER LESSON DENGAN MEDIA KARTU SISWA SMP

Pembelajaran matematika memerlukan strategi dan media belajar yang tepat yang salah satunya strategi peer lesson dengan media kartu agar hasil belajar matematika siswa menjadi optimal. Tujuan penelitian ini mendeskripsikan strategi peer lesson dengan media kartu yang dapat meningkatkan hasil belajar operasi aljabar. Rancangan penelitian ini adalah penelitian tindakan kelas melalui empat tahap yaitu tahap perencanaan, pelaksanaan, observasi dan refleksi. Subjek penelitian sebanyak 32 siswa dari kelas VIII SMPN 1 Aceh Besar. Instrumen penelitian menggunakan lembar observasi dan tes hasil belajar. Analisis data menggunakan analisis statistik deskriptif. Hasil penelitian menunjukkan bahwa ada peningkatan aktivitas guru dan aktivitas siswa melalui strategi peer lesson dengan media kartu. Hasil belajar operasi aljabar meningkat dari siklus I ke siklus II sebesar 12% dan rerata tes akhir sebesar 93,75%. Disimpulkan bahwa strategi peer lesson dengan media kartu dapat meningkatkan aktivitas guru dan siswa serta hasil belajar operasi aljabar. Kata kunci: Hasil Belajar Matematika, Operasi Aljabar, Strategi Peer Lesson, Media Kartu Mathematics learning requires the right strategy and learning media, one of which is the peer lesson strategy with card media so that students' mathematics learning outcomes become optimal. The purpose of this study is to describe the peer lesson strategy with card media that can improve the learning outcomes of algebraic operations. The design of this study is classroom action research through four stages, namely the stages of planning, implementation, observation and reflection. The subjects of the study were 32 students from class VIII of SMPN 1 Aceh Besar. The research instrument used observation sheets and test results. Data analysis using descriptive statistical analysis. The results showed that there was an increase in teacher activity and student activities through peer lesson strategies with card media. The learning outcomes of algebraic operations increased from cycle I to cycle II by 12% and the average final test was 93.75%. It was concluded that the peer lesson strategy with card media could increase the activity of teachers and students as well as the results of learning algebraic operations.  Key words: Mathematics Learning Outcomes, Algebraic Operations, Peer Lesson Strategies, Card Medi
