Mathline: Jurnal Matematika dan Pendidikan Matematika, Vol.2, No.1, 11-28. PENDAHULUAN Pada prakteknya masih banyak peserta didik yang enggan untuk mempelajari matematika. Tidak sedikit peserta didik yang menganggap bahwa matematika adalah pelajaran yang sulit. Bahkan, pelajaran yang menakutkan bagi peserta didik sehingga seringkali mengakibatkan rendahnya hasil belajar matematika.Rendahnya hasil belajar tersebut merupakan salah satu indikator bahwa, siswa mengalami kesulitan belajar. Kesulitan belajar tidak hanya dimiliki oleh siswa yang bersekolah di pedesaan namun juga dimiliki oleh siswa yang bersekolah di perkotaan. Hal tersebut sesuai dengan pendapat Djamarah (2011) yang menyatakan secara ringkas bahwa, kesulitan belajar tidak hanya dirasakan oleh sekolah modern di perkotaan, tapi juga dimiliki oleh sekolah tradisional di pedesaan dengan segala keminiman dan kesederhanaannya.Kesulitan belajar terjadi karena ketelitian, keterampilan, dan kecepatan dalam berpikir sangat diperlukan saat mempelajari matematika, tidak terkecuali pada materi garis dan sudut.Pada materi garis dan sudut siswa dituntut untuk bisa menghubungkan antar konsep, mengaplikasikan konsep, serta prinsip garis dan sudut. Sehingga, tidak aneh jika materi trigonometri merupakan materi yang sebagian besar dirasa sulit oleh siswa.Berdasarkan uraian di atas, Penelititertarik melakukan penelitian dengan judul "Kesulitan-Kesulitan Siswa dalam Mempelajari Materi Garis dan Sudut di SMP Negeri 4 Sindang".Denganpenelitian ini diharapkan guru dapatmengetahui letak kesulitan serta faktor-faktor yangmenyebabkan siswa mengalami kesulitan saat mengerjakansoal garis dan sudut. Fokus masalah dalam penelitian ini adalah (1) Kesulitan-kesulitan apa saja yang dialami siswa dalam mempelajari materi Garis dan Sudut?;(2) Faktor-faktor apa saja yang menyebabkan kesulitan belajar siswa dalam mempelajari materi Garis dan Sudut di rumah dan di sekolah?.Oleh karena itu tujuan dalam penelitian ini yakni untuk (1) Untuk mengetahui kesulitan-kesulitan apa saja yang dialami siswa dalam mempelajari materi Garis dan Sudut?;(2) Untuk faktor-faktor apa saja yang menyebabkan kesulitan belajar siswa dalam mempelajari materi Garis dan Sudut di rumah dan di sekolah.
