PENERAPAN LEMBAR KERJA PESERTA DIDIK BERBASIS PROBLEM BASED LEARNING UNTUK MENINGKATKAN KETERAMPILAN PROSES SAINS SISWA

THE IMPLEMENTATION OF STUDENT’S WORKSHEET BASED ON PROBLEM BASED LEARNING TO IMPROVE STUDENT’S SCIENCE PROCESS SKILL

Penelitian ini bertujuan untuk mendeskripsikan pengaruh penerapan Lembar Kerja Peserta Didik berbasis problem based learning terhadap peningkatan keterampilan proses sains siswa, aktivitas keterampilan proses sains siswa, dan respons siswa. Jenis penelitian yang digunakan adalah pre experimental dengan desain penelitian one group pre-test post-test menggunakan satu kelas eksperimen. Penelitian dilakukan di UPT SMP N 6 Gresik dengan sampel sebanyak 1 kelas yaitu kelas VII-G yang terdiri dari 30 siswa. Metode pengumpulan data yang digunakan adalah metode observasi, tes tulis, dan angket. Teknik analisis data yang digunakan yaitu deskriptif kuantitatif. Hasil penelitian yang diperoleh menunjukkan keterlaksanaan pembelajaran selama tiga kali pertemuan mendapat rata-rata kriteria terlaksana dengan baik. Keterampilan proses sains yang diamati berupa merumuskan masalah, merumuskan hipotesis, mengidentifikasi variabel, menginterpretasikan data, menarik kesimpulan, dan mengkomunikasikan. Rata-rata skor N-gain yang diperoleh sebesar 0,88 berkategori tinggi yang menunjukkan bahwa keterampilan proses sains siswa mengalami peningkatan. Proses pembelajaran juga direspon positif dengan perolehan respon rata-rata sebesar 93% dengan kriteria sangat efektif. Berdasarkan uraian di atas, dapat disimpulkan bahwa pembelajaran dengan menggunakan Lembar Kerja Peserta Didik berbasis problem based learning dapat meningkatkan keterampilan proses sains siswa pada materi pencemaran lingkungan.

This study aim to describe the implementation of students’ worksheets based on problem-based learning towards the improvement of students’ science process skills, the activity of students’ science process skills, and the students’ responses. The research used is pre-experimental with one group pre-test post-test research design by using one experiment class. The research is conducted at UPT SMP N 6 Gresik with a sample of one class namely VII-G that consists of 30 students. The data collection method used are observations, written tests, and questionnaires. The data analysis technique used is quantitative descriptive. The result of the study shows that the learning implementation for three meetings got the average criteria carried out well. The science process skills observed are formulating problems, formulating hypotheses, identifying variables, interpreting data, making conclusions, and communicating. The average N-gain score obtained is 0.88 in the high category which indicates that the students' science process skills have increased. The learning process is also responded positively with an average response of 93% with very effective criteria. Based on the description above, it can be concluded that learning by using students’  worksheets based on problem-based learning can enhance students' science process skills on environmental pollution material.
