PENINGKATAN KETERAMPILAN PROSES SAINS SISWA MENGGUNAKAN MODEL PEMBELAJARAN GUIDED INQUIRY PADA MATERI TEKANAN

ENHANCEMENT STUDENTS' SCIENCE PROCESS SKILLS USING GUIDED INQUIRY LEARNING MODEL ON PRESSURE TOPIC

Penelitian ini bertujuan untuk mendeskripsikan peningkatan keterampilan proses sains siswa dengan penerapan model pembelajaran guided inquiry. Desain yang digunakan dalam penelitian adalah pre-exsperimental design dengan rancangan penelitian one group pre-test post-test. Penelitian dilaksanakan dengan subjek dua kelas VIII di MTs Hasyim Asy’ari Sukodono, dimana kelas pertama memiliki 32 siswa, dan kelas kedua memiliki 36 siswa. Penelitian ini dilakukan di MTs Hasyim Asy’ari Sukodono karena belum pernah ada penelitian di sekolah ini sebelumnya, dengan alokasi waktu yang berbeda dari sekolah lain, yaitu 4x35 menit, dimana kurikulum menentukan alokasi waktu pembelajaran 5x40 menit dan belum pernah diterapkannya pembelajaran keterampilan proses sains. Teknik pengumpulan data melalui tes berupa soal uraian yang sesuai dengan indikator keterampilan proses sains. Hasil yang didapat berupa ketuntasan keterampilan proses sains, persentase ketercapaian tiap aspek keterampilan proses sains, n-gain pre-test dan post-test, dan n-gain tiap aspek keterampilan proses sains. Hasil penelitian menunjukkan bahwa terjadi peningkatan ketuntasan tiap aspek keterampilan proses sains, peningkatan presentase ketercapaian tiap aspek keterampilan proses sains, dan peningkatan n-gain tiap aspek keterampilan proses sains di dua kelas VIII masing-masing sebesar 0,59 dengan kategori sedang dan 0,64 dengan kategori sedang. Berdasarkan hasil tersebut, maka dapat disimpulkan bahwa model pembelajaran guided inquiry dapat meningkatkan keterampilan proses sains siswa, dan dapat diterapkan pada materi tekanan.

This research aims to describe the enhancement of students' science process skills with the application of guided inquiry model. The design used in the study was pre-experimental design with a research draft of one group pre-test post-test. Research was carried out with the subject of two classes VIII at MTs Hasyim Ash'ari Sukodono, where the first class had 32 students, and the second class had 36 students. This research was conducted in MTs Hasyim Asy'ari Sukodono because there has been no research in the school before, with the different time allocations from other schools, that is 4x35 minutes, where the curriculum determines the allocation of learning time 5x40 minutes and has not been established learning science process skills. Data collection techniques in the form of a question description that corresponds to the science process skills indicator. The result is the submission of science process skills, the percentage of achievement of each aspect of science process skills, n-gain pre-test and post-test, and n-gain every aspect of science process skills. The results showed that there has been an enhancement in every aspect of the science process skills, increasing the achievement percentage of each aspect of science process skills, and increasing the n-gain of each aspect of science process skills in two classes of 0.59 with medium category and 0.64 with medium category. Based on these results, it can be concluded that the guided inquiry model can enhance the students’ science process skills, and can be applied to the pressure topic.

Keywords: science process skills, guided inquiry, and pressure topic.
