ABSTRACT
This research aims to determine the more effective learning through
laboratory work-based learning and conventional-based learning to improve
science process skills and critical thinking skills of the students. This resaerch was
done at grade XMIIA students of SMAN 1 Seyegan by the sub-topic linear
motion (linear uniform motion and nonuniform linear motion).
The sample of this research was 58 students of XMIIA who were choosed
by using cluster random sampling technique and devided them into two classes.
The first class learned by using laboratory work-based learn and the second class
learned by using conventional-based learning. The data were obtained through
test, pre-test and post-test. Pre-test data were analysed to know the kind of statistic
that could be used to examine the hypothesis. Post-test data ware analysed by
using t-test to examine the hypothesis to know the studying result differences
(science process skills and critical thinking skills) between experiment class and
control class. Furthermore, the more effective learning used learning study

achievement and normalized gain effect size.
The result showed that there were differences of science process skills and
critical thinking skills of the students by using laboratory work-based learning and
conventional-based learning. It was shown that tarithmetic of two aspects were
greater than ttable and p < 0,05. The learning study achievement and normalized
gain score of experiment class was greater than control class for these aspects.
The effect size’s score of science process skills was 1,22 (high) and critical
thinking skills was 0,64 (high enough). Therefore, it could be concluded that
physics laboratory work-based learning is more effective than conventional-based
learning to improve science process skills and critical thinking skills of the
students.
Key words: Physics Learning, Laboratory Work, Science Process Skills and
Critical Thinking Skills.

ABSTRAK

Penelitian ini bertujuan untuk mengetahui pembelajaran yang lebih efektif
antara pembelajaran fisika berbasis kerja laboratorium dan pembelajaran
konvensional untuk meningkatkan keterampilan proses dan keterampilan berpikir
kritis siswa. Penelitian dilakukan pada kelas XMIIA di SMAN 1 Seyegan dengan
sub materi gerak lurus (GLB dan GLBB).
Sampel pada penelitian ini penelitian ini adalah 58 siswa kelas XMIIA
yang dipilih menggunakan teknik cluster random sampling yang kemudian dibagi
menjadi dua kelas. Kelas pertama diberi perlakuan pembelajaran fisika berbasis
kerja laboratorium dan kelas kedua dengan metode pembelajaran konvensional.
Data kemampuan keterampilan proses dan keterampilan berpikir kritis siswa
diperoleh dengan cara tes yaitu pre-test dan post-test. Data pre-test dianalisis
untuk mengetahui jenis statistik yang akan digunakan untuk menguji hipotesis.
Data post-test dianalisis menggunakan uji t untuk menguji hipotesis yaitu
mengetahui perbedaan hasil belajar (keteramilan proses dan keterampilan berpikir
kritis) antara kelas eksperimen dan kelas kontrol. Sedangkan untuk mengetahui

pembelajaran yang lebih efektif menggunakan ketercapaian hasil belajar dan
normalized gain.
Hasil penelitian menunjukkan bahwa ada perbedaan kemampuan
keterampilan proses dan keterampilan berpikir kritis siswa yang mengikuti
pembelajaran fisika berbasis kerja laboratorium dan pembelajaran konvensional.
Hal ini ditunjukkan oleh nilai t hitung kedua aspek lebih besar dari t tabel dan p < 0,05.
Selain itu, pada kelas eksperimen memiliki ketercapaian hasil belajar dan
normalized gain yang lebih tinggi untuk aspek keterampilan proses dan
keterampilan berpikir kritis. Nilai effect size pada aspek keterampilan proses
adalah 1,22 (tinggi) dan keterampilan berpikir kritis adalah 0,64 (cukup tinggi).
Oleh karena itu, dapat disimpulkan bahwa pembelajaran fisika berbasis kerja
laboratorium lebih efektif dibandingkan dengan pembelajaran konvensional untuk
meningkatkan keterampilan proses dan keterampilan berpikir kritis siswa.
Kata kunci : Pembelajaran fisika, kerja laboratorium, keterampilan proses,
keterampilan berpikir kritis.
