Pengaruh Penggunaan Media Tangram Pada Mata Pelajaran Matematika Terhadap Hasil Belajar Siswa Kelas III SD Negeri 3 Serdang Kecamatan Tanjung Bintang Kabupaten Lampung Selatan

Abstract

The perspective of teaching in this modern era is only limited to conveying knowledge which is considered no longer appropriate to the situation. So we need learning media that can help deliver material to students, one of which is tangram learning media. This study aims to determine whether there is an effect of the use of tangram media in mathematics on the learning outcomes of third grade students at SD Negeri 3 Serdang, Tanjung Bintang District, South Lampung Regency. This type of research is quantitative with pre-experimental in the form of one group pretest-posttest design. The population in this study were third grade students at SD Negeri 3 Serdang, Tanjung Bintang District, South Lampung Regency. The sample of this research is 20 students. Data collection techniques used tests, documentation, data analysis techniques, and t-tests. The results of this study are shown by the results of the t-test (paired sample t test) for the same sample with different treatments (prestest-posttest) with tcount (-18.779) > ttable (-2.101) with a Sig (2-tailed) level of 0.000 <0.05 which proves that there is an effect of the use of tangram media in mathematics subjects on learning outcomes.
