Abstract

Abstrak

Penelitian ini bertujuan untuk meningkatkan hasil belajar siswa kelas VA SD Negeri Giwangan menggunakan model pembelajaran kooperatif tipe Number Head Together pada mata pelajaran matematika materi perkalian dan pembagian pecahan. Penelitian tindakan kelas (PTK) ini menggunakan model Kemmis dan Taggart . Penelitian ini terdiri dari tiga langkah yaitu: perencanaan, tindakan dan observasi, refleksi. Subyek penelitian berjumlah 30 siswa. Penelitian ini dilakukan dalam dua siklus. Teknik pengumpulan data melalui tes, observasi, dan dokumentasi. Hasil penelitian ini menunjukkan telah terjadi peningkatan hasil belajar. Hasil tes pra siklus, ada 8 siswa atau 26,66% dari 30 siswa yang mendapat nilai ≥70, siklus I ada 21 siswa atau 70% dari seluruh siswa yang mendapat nilai ≥70, sedangkan hasil tes pada siklus II ada 28 siswa atau 93,33% dari seluruh siswa yang mendapatkan nilai ≥70. Hasil penelitian ini menunjukan bahwa dengan menggunakan Numbered Heads Together dapat meningkatkan hasil belajar dari siklus I ke siklus II sebanyak 23,33%.

Abstract

This research aims at improving students learning achievement in class VA of SD Negeri Giwangan using cooperative learning model especially Numbered Heads Together type in mathematics subject focusing on fraction multiplication and division learning. This Classroom Action Research used Kemmis and Taggart model. This research consisted of following steps; plan, action and observation, reflection. The subject of this research were 30 students. The execution of this research was conducted in 2 cycles. The data collecting techniques were test, observation, and documentation. The result of this research shows that the implementation of Numbered Heads Together models can improve the matematics fraction multiplication and division learning achievement. In pre cycle, there were 8 students or approximately 26,66% of 30 students who got score more than 70 (≥70). In cycle 1, there were 70% students (21 students from 30) that achieved score more than 70. Later in cycle 2, there were 28 students from 30 (93,33%) who got score more than 70. These result shows that the implementation of Numbered Heads Together can improve learning achievement as much as 23,33% from cycle I to cycle II.
