INDONESIA:

Pengembangan bahan ajar matematika merupakan salah satu sarana guna membantu memahamkan siswa dalam pembelajaran. Melalui bahan ajar, diharapkan dapat memotivasi siswa dalam kegiatan pembelajaran serta dapat meningkatkan hasil belajar . Bahan ajar yang dapat mendukung proses pembelajaran matematika adalah bahan ajar ensiklopedia bangun datar siswa kelas V SD/MI. Materi pokok yang dibahas adalah tentang bangun datar. Materi ini menjelaskan tentang berbagai macam sifat-sifat bangun dan hubungan antar bangun serta manfaat penggunaan bangun datar dalam kehidupan sehari-hari. Tujuan penelitian ini adalah mengembangkan bahan ajar matematika berbasis ensiklopedia pokok bahasan bangun datar dengan objek penelitian siswa kelas V MI Irsyadut Tholibin Tugu Rejotangan.

Metode penelitian yang digunakan oleh peneliti adalah Research and Development, yang mengacu pada model Dick and Carrey. Hasil dari penelitian pengembangan bahan ajar ensiklopedia bangun datar dalam mata pelajaran matematika memenuhi kriteria valid dengan hasil uji ahli materi mencapai tingkat kevalidan 82,67%, ahli media mencapai 90,76%, ahli mata pelajaran mencapai 81,54%, dan hasil uji coba lapangan mencapai 99,06%, hasil belajar siswa rata-rata nilai pre-test 73,4 dan nilai post-test 87. Pada uji-t manual dengan tingkat kemaknaan 0,05 diperoleh hasil t hitung ≥ t tabel yaitu 6,84 ≥ 2,045 artinya Ho ditolak dan Ha diterima. Sehingga, terdapat perbedaan yang signifikan terhadap bahan ajar yang dikembangkan. Hal ini menunjukkan bahwa produk yang dikembangkan memiliki kualifikasi tingkat kevalidan yang tinggi, sehingga bahan ajar layak digunakan dalam pembelajaran.

The development of mathematics teaching materials is one of the means to assist students in learning activities. Through teaching materials,it is expected to motivate students in learning activities as well as to improve learning outcomes. One of teaching materials that can support the learning process of mathematics is Encyclopedia of Two-dimensional figures for the fifth grade of SD/MI. Subject matter discussed was about two-dimensional figures. This material describes a wide range of two-dimensional figures and relationships between them as well as the benefits of using them in everyday life. The purpose of this research is to develop mathematical teaching materials based on encyclopedia of two-dimensional figures with the research object fifth grade students in MI Irsyadut Tholibin, Tugu Rejotangan.

The method used by the researchers is Reserch and Development , which refers to the model of Dick and Carrey .The results of the research development of teaching materials encyclopedia of two-dimensional figures have valid criteria with test results;subjectmatter experts reached 82.67%, media expert reached 90.76% , subject experts reached 81.54%, and the field test results reached 99.06%, student learning outcomes average on pre-test reached 73,4 value and the score of post-test reached 87. In the manual t-test with a significance level of 0.05, obtained results as t–calculation ≥ t table which is 6,84 ≥ 2,045 while Ho is rejected and Ha is accepted. Thus, there is a significant difference to the developed teaching materials. This indicates that the developed product has a high level of validity qualifications and worthy to use as teaching materials in learning activities.
