EFEKTIVITAS MODEL PEMBELAJARAN PROBLEM BASED LEARNING (PBL) DALAM MENINGKATKAN KETERAMPILAN PROSES SAINS PESERTA DIDIK FASE C SD
Penelitian ini dilatarbelakangi oleh rendahnya keterampilan proses sains peserta didik pada pembelajaran IPA khususnya pada materi sampah dan pengelolaannya. Berdasarkan wawancara, ditemukan bahwa keterampilan proses sains pada materi tersebut cenderung rendah. Di mana peserta didik cenderung kurang terampil dan kesulitan dalam keterampilan proses sains mengamati, mengajukan pertanyaan, merumuskan hipotesis, mengklasifikasikan, menginterpretasi, mengkomunikasikan, dan menerapkan konsep. Pada penelitian ini peneliti, menerapkan model pembelajaran Problem Based Learning (PBL) untuk diketahui efektivitasnya terhadap keterampilan proses sains pada materi sampah dan pengelolaannya. Model pembelajaran Problem Based Learning (PBL) merupakan model pembelajaran yang terdiri dari tahapan orientasi peserta didik pada masalah, mengorganisasikan peserta didik untuk belajar,membimbing penyelidikan individu maupunkelompok, dan menganalisis dan mengevaluasi proses pemecahan masalah. Penelitian ini menggunakan pendekatan kuantitatif metode Pre-Eksperimen dengan one group pre-test post-test design. Sampel pada penelitian ini yaitu 28 peserta didik fase C salah satu sekolah dasar di Kab. Bandung Barat. Instrumen yang digunakan yaitu tes tertulis dengan jenis soal uraian. Analisis data yang digunakan adalah uji normalitas, uji hipotesis, dan uji N-Gain. Berdasarkan data yang diperoleh, rata-rata hasil pre-test dan post-test mengalami peningkatan yaitu dari 29,93 menjadi 75,25. Berdasarkan uji hipotesis, diperoleh nilai signifikansi 0,000 < 0,05 yang artinya Ho ditolak dan H1 diterima serta menunjukkan peningkatan keterampilan proses sains yang signifikan. Dalam uji N-Gain diperoleh nilai 0,65 yang berarti skor N-Gain berada pada kategori “sedang”. Sedangkan untuk presentase N-Gain menunjukkan nilai 65, maka kategori tafsiran efektivitas gain model pembelajaran Problem Based Learning (PBL) berada pada tingkat “cukup efektif” untuk meningkatkan keterampilan proses sains pada peserta didik fase C Sekolah Dasar. This research is motivated by the low science process skills of students in science learning, especially in waste materials and their management. Based on interviews, it was found that the science process skills in the material tended to be low. Where students tend to be less skilled and have difficulties in the skills of the science process of observing, asking questions, formulating hypotheses, classifying, interpreting, communicating, and applying concepts. In this study, the researcher applied the Problem Based Learning (PBL) learning model to determine its effectiveness on science process skills on waste materials and their management. The Problem Based Learning (PBL) learning model is a learning model that consists of the stages of orientation of students to problems, organizing students to learn, guiding individual and group investigations, and analyzing and evaluating the problem-solving process. This study uses a quantitative approach of the Pre-Experiment method with one group pre-test post-test design. The sample in this study is 28 phase C students of one of the elementary schools in West Bandung Regency. The instrument used is a written test with a type of description question. The data analysis used was a normality test, a hypothesis test, and an N-Gain test. Based on the data obtained, the average pre-test and post-test results have increased, from 29,93 to 75,25. Based on the hypothesis test, a significance value of 0,000 < 0,05 was obtained, which means that Ho was rejected and H1 was accepted and showed a significant improvement in science process skills. In the N-Gain test, a value of 0.65 was obtained, which means that the N-Gain score is in the "moderate" category. As for the N-Gain percentage showing a value of 65, the category of interpretation of the effectiveness of the gain of the Problem Based Learning (PBL) learning model is at the level of "quite effective" to improve science process skills in phase C students of elementary school.
