Summary
Data penggunaan waktu siswa dan guru disajikan dalam bentuk grafik berikut : Menit Untuk Siswa. Sesuai dengan rancangan penelitian yang telah disusun dan hasil penelitian yang diperoleh maka pada pembahasan ini akan dititikberatkan pada tiga hal yaitu (1) partisipasi siswa dalam proses pembelajaran (2) prosentase penggunaan waktu antara guru dan siswa selama proses belajar – mengajar dan (3) prestasi belajar siswa. Berdasarkan analisis data yang diperoleh menunjukkan bahwa pada siklus I partisipasi siswa sebesar 58,1% yang berarti dalam kategori C (skore C : 4160%) dan pada siklus II sebesar 58,0% yang berarti juga dalam kategori C. Walaupun antara siklus I dan II partisipasi siswa tidak menunjukkan peningkatan namun hal tersebut secara umum sudah menunjukkan kemajuan yang menggembirakan bila dirunut dari awal sebelum digunakannya model pembelajaran NHT dimana siswa dalam pembelajaran tidak bergairah, pasif, berbicara pada teman, dan main sms. Meningkatnya partisipasi siswa dalam pembelajaran tersebut juga telah dibuktikan dari hasil penelitian Hayati (2008:3)
