ABSTRAK
Modul fisika berbasis inkuiri terbimbing pada materi listrik dinamis perlu
dikembangkan untuk meningkatkan keterampilan berpikir kritis dan hasil belajar siswa.
Penelitian ini bertujuan untuk mengetahui: 1) pengembangan Modul Fisika Berbasis
Inkuiri Terbimbing, 2) kelayakan produk Modul Fisika Berbasis Inkuiri Terbimbing, 3)
efektivitas Modul Fisika Berbasis Inkuiri Terbimbing untuk meningkatkan keterampilan
berpikir kritis siswa kelas X SMA/MA.
Jenis penelitian ini adalah penelitian pengembangan (Research and
Development) termodifikasi dari Borg and Gall (1983). Sampel penelitian
pengembangan meliputi: 1) sampel uji coba produk awal sejumlah 2 validator ahli
(materi, media dan bahasa), 2 praktisi pendidikan dan 2 teman sejawat, 2) sampel uji
coba lapangan terbatas sejumlah 10 siswa kelas X2 SMA Muhammadiyah 1
Temanggung, dan 3) sampel uji lapangan operasional sejumlah 26 siswa kelas X1 SMA
Muhammadiyah 1 Temanggung. Instrumen yang digunakan adalah angket, lembar
observasi, wawancara, dan tes. Uji lapangan operasional menggunakan one group
pretest-posttest design. Data keterampilan berpikir kritis (hasil belajar kognitif) siswa
diuji menggunakan uji t berpasangan dan dihitung dengan N-gain ternormalisasi.
Hasil penelitian pengembangan sebagai berikut: 1) karakteristik pengembangan
modul fisika berbasis inkuiri terbimbing untuk meningkatkan keterampilan berpikir
kritis siswa kelas X SMA/MA yaitu menggunakan teknik R&D (research and
development) dari Borg and Gall (1983: 775) termodifikasi melalui 10 tahap dengan
tahapan terakhir dilakukan diseminasi saja tanpa dilakukannya implementasi produk, 2)
kelayakan Modul Fisika Berbasis Inkuiri Terbimbing setelah dilakukannya uji coba
produk awal, uji coba lapangan terbatas, uji lapangan operasional dan diseminasi dan
implementasi didapatkan rata-rata persentase sebesar 85,11% yang dikategorikan
?Sangat Baik?, 3) efektivitas Modul Fisika Berbasis Inkuiri Terbimbing untuk
meningkatkan keterampilan berpikir kritis siswa didapatkan nilai N-gain dari
keterampilan berpikir kritis (hasil belajar kognitif) sebesar 0,564 dikategorikan
?Sedang?.
Kata kunci: Penelitian Pengembangan, Modul, Inkuiri Terbimbing, dan Keterampilan
Berpikir Kritis.
ABSTRACT
Physics module based guide inquiry on electro dynamic should be developed to
increase critical thinking skills and students achievement. This research aims are to: 1)
identify the develop product of Guided Inquiry-based Physics Module, 2) identify the
properness of Guided Inquiry-based Physics Module, 3) identify the effectiveness of
Guided Inquiry-based Physics Module to Increase Students’ Skill of Critical Thinking
in Class X SMA/MA.
This Research and Development (R&D) is modified from Borg and Gall model
(1983). Sample of the research were: 1) sample of initial product trial: 2 validations
(Contents, design, language), education practitioners and collage friend, 2) sample of
preliminary field test: 10 students in X2 class SMA Muhammadiyah 1 Temanggung and
3) sample of operational field test: 26 students in X1 class SMA Muhammadiyah 1
Temanggung. The instruments used were questionnaire, observation sheets, interview
and test. One group pretest-posttest design was used in the operational field test. Data of
critical thinking skill (students’ cognitive achievement) were tested using paired t test
and were scored using N-gain score.
Research findings are presented as follow: 1) guided Inquiry-based Physics
Module to Increase Students’ Skill of Critical Thinking was developed using modified
model of Gall, Borg, and Gall (1983), through: research and data collection, planning,
initial product development, initial product trial, product I revision, preliminary field
test, product II revision, operational field test, final product revision, dissemination and
implementation; 2) properness of Guided Inquiry-based Physics Module to Increase
Students’ Skill of Critical Thinking was identified after initial product trial, preliminary,
operational field test and dissemination and implementation, the mean percentage score
was 85,11% and it was category “Very Good”; 3) effectiveness of Guided Inquiry-based
Physics Module to Increase Students’ Skill of Critical Thinking was identified from Ngain
score of critical thinking skill (students’ cognitive achievement): 0,564 (“Medium
category”).
