Abstract

Abstrak           Hingga saat ini bila dibandingkan dengan negara-negara lain di dunia, Indonesia masih berada di peringkat terbawah. Kemampuan siswa Indonesia dalam menyelesaikan soal-soal yang menuntut kemampuan menelaah, memberi alasan, mengkomunikasikannya secara efektif, memecahkan masalah dan menginterpretasikan permasalahan dalam berbagai situasi masih sangat lemah. Untuk membantu meningkatkan kemampuan siswa dalam menyelesaikan soal matematika setara PISA, penulis melakukan penelitian dengan judul: “Meningkatkan Kemampuan Siswa Sekolah Menengah Atas dalam  Menyelesaikan Soal  Matematika Setara PISA Melalui Pendekatan Konstruktivisme”. Penelitian ini mengukur kemampuan menyelesaikan soal matematika setara PISA siswa SMA. Salah satu alternatif pembelajaran yang memungkinkan dapat meningkatkan kemampuan siswa dalam menyelesaikan soal matematika setara PISA adalah Pendekatan Pembelajaran Konstruktivisme. Belajar menggunakan pendekatan konstruktivisme memberikan kesempatan kepada siswa untuk menkonstruksi pengalamannya sedikit demi sedikit. Tujuan penelitian ini untuk mengetahui peningkatan kemampuan siswa menyelesaikan soal matematika setara PISA dengan menggunakan pendekatan pembelajaran konstruktivisme, serta mengetahui sikap siswa selama pembelajaran. Populasi dalam penelitian ini adalah siswa SMA Negeri 1 Lhokseumawe, sedangkan sampelnya adalah siswa kelas X SMA Negeri 1 Lhokseumawe. Dua kelas dipilih secara random sampling  untuk dijadikan kelas kontrol dan kelas eksperimen, dari kedua kelas tersebut lalu dipilih 20 siswa yang berumur sekitar 15 tahun. Instrument yang digunakan terdiri dari tes kemampuan menyelesaikan soal matematika setara PISA, angket sikap siswa, dan lembar observasi. Berdasarkan analisa data menggunakan SPSS 17 for windows dan Microsoft excel 2007, dapat disimpulkan bahwa peningkatan kemampuan menyelesaikan soal matematika setara PISA siswa yang memperoleh pembelajaran menggunakan pendekatan konstruktivisme lebih baik daripada peningkatan kemampuan menyelesaikan soal matematika setara PISA siswa yang memperoleh pembelajaran konvensional. Siswa memiliki sikap positif terhadap pembelajaran menggunakan pendekatan konstruktivisme; aktivitas siswa setelah memperoleh pembelajaran menggunakan pendekatan konstruktivisme secara keseluruhan baik.Kata Kunci: Konstruktivisme, Literasi Matematis, PISA

Abstract

Abstrak             Model pembelajaran ARCS (attention, relevance, confidence, satisfaction) merupakan model yang dikembangkan berdasarkan review tentang motivasi dengan tujuan mengaktifkan siswa belajar.Selama proses pembelajaran berlangsung aspek motivasi sangat mempengaruhi hasil belajar. Statistika merupakan salah satu materi pelajaran yang harus dikuasai siswa namun di SMANegeri2 RSBI Banda Aceh hasil belajar siswa rendah. Model pembelajaran ARCS dalam mempelajari materi statistika dapat menjadi alternatif yang dapat diterapkan dengan harapan siswa termotivasi dalam belajar. Penelitian ini bertujuan untuk mengetahui ketuntasan belajar siswa, perhatian (attention), keterkaitan bahan ajar dengan kebutuhan siswa (relevance), percaya diri (confidence), dan kepuasan (satisfaction) siswa pada materi statistika yang diajarkan dengan model pembelajaran ARCS. Pendekatan penelitian ini adalah penelitian kuantitatif yang bersifat deskriptif. Penelitian ini merupakan pre-eksperimental design  jenis one shot case study. Penelitian ini dilakukan di kelas XI SMA Negeri 2 RSBI Banda Aceh dengan KKM materi Statistika 75. Subjek dari penelitian ini adalah siswa kelas XI IA 1 sebanyak 24 siswa. Pengumpulan data dilakukan dengan menggunakan tes hasil belajar, angket motivasi siswa, wawancara, dan lembar observasi. Hasil penelitian menunjukkan bahwa perhatian siswa, keterkaitan bahan ajar dengan kebutuhan siswa, percaya diri siswa, dan kepuasan siswa dikategorikan baik  untuk setiap pertemuan. Respon siswa pada setiap aspek ARCS dikategorikan positif. Namun ketuntasan secara klasikal belum terpenuhi karena persentase siswa yang tuntas belajar  secara individu (KKM = 75) kurang dari 85%. Demikian pembelajaran dengan menggunakan model pembelajaran ARCS belum efektif.Kata kunci: model pembelajaran ARCS, materi statistika
