Penerapan Model Pembelajaran Problem Based Learning (PBL) untuk Meningkatkan Kemampuan Peserta Didik Memecahkan Masalah pada Materi Zat Aditif

Implementation of Problem Based Learning Model to Improve Student’s Ability to Solve Problems on Additive Material

    Tujuan penelitian ini adalah untuk memperoleh deskripsi tentang efektivitas penerapan model pembelajaran Problem Based Learning (PBL) pada Materi Zat Aditif  terhadap kemampuan peserta didik memecahan masalah yang ditinjau dari : Hasil peningkatan kemampuan pemecahan masalah, keterlaksanaan penerapan model pembelajaran Problem Based Learning (PBL), dan respon peserta didik. Metode penelitian ini adalah kuantitatif dengan quasi experimental design. Data dikumpulkan  menggunakan teknik tes, observasi, dan angket. Teknik observasi digunakan untuk keterlaksaan proses pembelajaran, teknik tes digunakan untuk melihat peningkatan kemampuan pemecahan masalah, sedangkan untuk respon siswa digunakan lembar angket. Hasil penelitian menunjukkan bahwa hasil effect size sebesar 0,923 yang berarti pembelajaran IPA pada kelas eksperimen memiliki efektifias lebih tinggi, keterlaksanaan proses pembelajaran mendapatkan skor modus 4 yang berarti terlaksana dengan sangat baik, dan mendapatkan respon positif dari siswa. Hal ini dapat disimpulkan bahwa model pembelajaran problem based learning dapat digunakan untuk meningkatkan kemampuan pemecahan masalah.

The purpose of this study was to obtain a description of the effectiveness of the application of the Problem Based Learning (PBL) learning model on Additive Material on students' ability to solve problems as reviewed from: Results of increasing problem solving abilities, implementation of the Problem Based Learning (PBL) learning model, and student responses. This research method is quantitative with a quasi-experimental design. Data were collected using test, observation, and questionnaire techniques. Observation techniques are used for the implementation of the learning process, Test techniques are used to see the increase in problem solving abilities, while questionnaire sheets are used for student responses. The results of the study showed that the effect size results were 0.923, which means that science learning in the experimental class has higher effectiveness, the implementation of the learning process gets a mode score of 4 which means it is implemented very well, and gets positive responses from students. Thus, it can be concluded that the problem-based learning model can be used to improve problem-solving skills.
