IMPLEMENTASI MODEL PEMBELAJARAN INKUIRI TERSTRUKTUR UNTUK MENINGKATKAN KETERAMPILAN PROSES SAINS SISWA PADA MATERI SISTEM PEREDARAN DARAH

IMPLEMENTATION OF STRUCTURED INQUIRY LEARNING MODEL TO IMPROVE STUDENTS SCIENCE PROCESS SKILLS IN BLOOD CIRCULATION SYSTEM MATERIALS

Penelitian ini bertujuan mendeskripsikan keterlaksanaan pembelajaran, peningkatan keterampilan proses sains dasar, dan respons  siswa terhadap implementasi model pembelajaran inkuiri terstruktur materi sistem peredaran darah manusia. Jenis penelitian ini yakni pre-experimental design dengan desain penelitian one group pretest posttest yang dikembangkan menjadi kelas eksperimen dan replikasi. Subjek penelitian ini yaitu siswa kelas VIII-A dan VIII-B SMPN 46 Surabaya, setiap kelas berjumlah 29 siswa. Metode pengumpulan data yang digunakan berupa obervasi, tes dan angket. Berdasarkan hasil analisis data menunjukkan bahwa keterlaksanaan pembelajaran inkuiri terstruktur terlaksana dengan sangat baik. Hasil Respons siswa positif dengan rerata persentase sebesar 87.9%. Peningkatan keterampilan proses sains ditinjau dari uji N-gain pada kelas VIII-A diperoleh hasil sebesar 0.72 dengan persentase peningkatan 42% kategori sedang dan 58% kategori tinggi, sedangkan rerata N-gain VIII-B 0.69 dengan persentase sebesar 47 % kategori sedang dan 53% kategori tinggi. Hasil uji-t tidak berpasangan nilai sig 0.517 > 0.05 menunjukkan rerata N-gain KPS dasar siswa kelas VIII-A sama dengan rerata N-gain KPS dasar kelas VIII-B. Disimpulkan bahwa implementasi model pembelajaran inkuiri terstruktur dapat meningkatkan keterampilan proses sains siswa, respons positif siswa, dan tidak terdapat perbedaan signifikan pada rerata peningkatan KPS dasar kedua kelas.

This study aims to describe the implementation of learning, improvement of basic science process skills, and student responses to the implementation of a structured inquiry learning model for the human circulatory system. This type of research is a pre-experimental design with a one group pretest posttest research design which was developed into an experimental and replication class. The subjects of this study were students of class VIII-A and VIII-B of SMPN 46 Surabaya, each class consisted of 29 students. Data collection methods used in the form of observations, tests and questionnaires. Based on the results of data analysis shows that the implementation of structured inquiry learning is very well done. Results Student responses were positive with a mean percentage of 87.9%. The increase in science process skills in terms of the N-gain test in class VIII-A obtained the results of 0.72 with a percentage increase of 42% in the medium category and 58% in the high category, while the average N-gain VIII-B was 0.69 with a percentage of 47% in the medium category and 53% high category. The results of the unpaired t-test sig value of 0.517 sig value. > 0.05 indicates the average N-gain of basic SPS students in grades VIII-A is the same as the average N-gain of basic SPS grades VIII-B. It was concluded that the implementation of the structured inquiry learning model could improve students' science process skills, students' positive responses, and there was no significant difference in the average increase in basic SPS for the two classes.
