Penerapan Model Numbered Head Together Berbantuan Media Konkret untuk Meningkatkan Hasil Belajar Matematika Kelas 1 SDN 1 Purwonegoro

Abstract

Findings of mathematics learning problems in first grade of SDN 1 Purwonegoro resulted in low student motivation and impact on learning outcomes. Teachers have not used innovative learning models and media. So, the researcher chose the numbered head together model with concrete media. The purpose of this research is to improve teacher skills, student activities, and learning outcomes. This research is a collaborative classroom action research. The research subjects were teachers and students. Data collection techniques using tests, observations, and field notes. The results showed that the data on teacher skills in cycle I was 24, cycle II was 27, and cycle III was 30. Student activities in cycle I averaged 26.39, cycle II was 27.22, and cycle III was 29.28. The average mathematics learning outcomes in the first cycle was 79.93, the second cycle was 81.82, and the third cycle was 89.46. Thus, the application of the numbered head together model assisted by concrete media can improve teacher skills, student activities, and mathematics learning outcomes in first grade of SDN 1 Purwonegoro.

Temuan permasalahan pembelajaran matematika di kelas I SDN 1 Purwonegoro mengakibatkan rendahnya motivasi belajar siswa dan berimbas pada hasil belajar. Guru belum menggunakan model dan media pembelajaran inovatif. Maka, peneliti memilih model numbered head together dengan media konkret. Tujuan penelitian ini untuk meningkatkan keterampilan guru, aktivitas siswa, dan hasil belajar. Penelitian ini adalah penelitian tindakan kelas kolaboratif. Subjek penelitian adalah guru dan siswa. Teknik pengumpulan data menggunakan tes, observasi, dan catatan lapangan. Hasil penelitian menunjukkan data keterampilan guru siklus I sebesar 24, siklus II sebesar 27, dan siklus III sebesar 30. Aktivitas siswa siklus I rata-rata skor sebesar 26,39, siklus II sebesar 27,22, dan siklus III sebesar 29,28. Hasil belajar matematika rata-rata pada siklus I 79,93, siklus II 81,82, dan siklus III 89,46. Dengan demikian, penerapan model numbered head together berbantuan media konkret dapat meningkatkan keterampilan guru, aktivitas siswa, dan hasil belajar matematika pada siswa kelas I SDN 1 Purwonegoro.
