Abstract

Penelitian ini bertujuan untuk mengetahui apakah hasil belajar matematika siswa dengan menerapkan strategi pembelajaran aktif tipe Practice Rehearsal Pairs lebih baik daripada hasil belajar matematika siswa dengan menerapkan pembelajaran konvensional dan bagaimanakah perkembangan aktivitas belajar siswa dengan menggunakan strategi pembelajaran aktif tipe Practice Rehearsal Pairs di kelas VIII SMPN 9 Padang. Jenis penelitian ini adalah penelitian eksperimen dengan rancangan random terhadap subjek. Populasi penelitian ini adalah seluruh siswa kelas VIII dengan kelas eksperimen yaitu VIII.3 dan kelas kontrol yaitu VIII.5. Tes hasil belajar matematika dengan reliabilitas tes adalah r11=0,07. Hasil analisis aktivitas siswa mengalami peningkatan yaitu 57% sampai 84%. Hasil dari uji hipotesis diperoleh t hitung=0,83 dan t tabel=1,67 maka hipotesis ditolak. Jadi hasil belajar matematika siswa dengan menerapkan strategi pembelajaran aktif tipe Practice Rehearsal Pairs sama dengan hasil belajar matematika siswa dengan menerapkan pembelajaran konvensional di kelas VIII SMPN 9 Padang dan perkembangan aktivitas siswa mengalami peningkatan.

Abstract

AbstractThis research was instigated with inadequate laboratory facilities and no green chemistry based practical work guideline at school. This research aimed at finding out validity and practicality levels of green chemistry based practical work guideline on electrochemistry lesson that was designed. Design & development research (DDR) method was used in this research consisted of 4 steps—analysis, design, development, and evaluation. This research was conducted to the twelfth-grade students of MIPA at State Senior High School 1 Kampar. The research findings showed that the percentages of green chemistry based practical work guideline by media and material experts continuously were 95% and 96.43% with very valid criteria. The practicality percentages by chemistry subject teachers and student response continuously were 91.96% and 83% with very practical criteria. Based on these data, it could be concluded that green chemistry based practical work guideline was very valid and very practical to be used as a teaching material on electrochemistry lesson.Keywords : DDR, Practical Work Guideline, Green Chemistry, Electrochemistry
