ABSTRAK
Kerakteristik pembelajaran fisika di SMA melibatkan peran siswa untuk aktif selama
proses pembelajaran fisika berlangsung melalui pengamatan, pengukuran, penarikan data,
dan penarikan kesimpulan. Akan tetapi, kebanyakan guru di sekolah belum optimal dalam
melibatkan siswa secara aktif selama proses pembelajaran. Tujuan penelitian ini untuk
mengetahui pengaruh model pembelajaran, motivasi belajar, dan keterampilan berpikir
kritis terhadap prestasi belajar, serta mengetahui interaksi antara model pembelajaran,
motivasi belajar, keterampilan berpikir kritis terhadap prestasi belajar fisika siswa.
Penelitian ini merupakan penelitian quasi eksperimen dengan populasi penelitian
kelas X MIPA SMAN 1 Mojo, Kabupaten Kediri. Teknik pemilihan sampel menggunakan
cluster random sampling yaitu pemilihan sampel secara acak dengan menggunakan undian.
Sampel populasi ini terdiri dari dua kelas yaitu kelas eksperimen 1 dengan model problem
solving dan eksperimen 2 dengan model problem posing. Data prestasi belajar pengetahuan
diperoleh dari tes pilihan ganda, data keterampilan berpikir kritis diperoleh dari tes uraian,
sedangakan prestasi sikap, keterampilan dan motivasi belajar diperoleh dari hasil observasi.
Data yang diperoleh kemudian dianalisis dengan anava tiga jalan menggunakan General
Linier Model.
Hasil analisis menunjukkan bahwa pengaruh model problem solving lebih baik
dibandingkan model problem posing baik ditinjau dari skor motivasi belajar, keterampilan
berpikir kritis, maupun prestasi belajar.
Kata kunci: problem solving, problem posing, motivasi belajar, keterampilan berpikir kritis,
prestasi belajar
ABTRACT
The characteristic of physic study in Senior High School is that it is always engaging
students to be active during the process of teaching and learning through observation,
measuring, data collection, and making conclusion. However, there are teachers who are
still lack in optimizing students in the process of teaching and learning. The purpose of this
observation was to find out the effect of learning model, learning motivation, critical
thinking skill toward learning achievment. It was also to observe interaction between
learning model, learning motivation, and chritical thingking skill toward students.
achievement in learning physic.
The observation is quasi experiment using tenth grade of science class SMAN 1 Mojo
Kediri as the population. Samples selection technique was using cluster random sampling
which is choosing sample randomly using lottery. This population samples was including
two classes, the first one was experimenty class 1 using problem solving model and the
second class was experiment class 2 using problem posing model. The data of cognitive
learning achievement was gained from multiple choice tests, critical thinking skill data was
from eassy test, as for attitude achievement, skill and learning motivation were derived
from observation result. The data obtained was than being analyzed with three ways anava
using General Linier Model.
The analysis result showed that the effect of problem solving model is better than
problem posing model as referred to learning motivation, score, critical thinking skills and
also learning achievement.
