Problem-Based Learning To Improve Concept Understanding and Critical Thinking Ability of Science Education Undergraduate Students

Abstract

This reserach was conducted to improve conceptual understanding and critical thinking ability of fourth-semester students of the Science education study program, Bengkulu University by applying PBL. The research method used in this study is quasi experimental, which in its implementation uses single class or one group pretest-posttest design. The test question was the instrument used in this study. The findings showed that there was an improvement in students‘ conceptual understanding and critical thinking ability of students‘ since implementing problem-based learning models in environmental chemistry courses. This improvement can be seen from the results of the gain test for each class group on the test of conceptual understanding and critical thinking ability which are in the "medium" category, while the t-test results for concept understanding and critical thinking ability show a significant difference (0.000 <0.05). ), In other words, the implementation of the PBL learning influences the students‘ conceptual understanding and critical thinking ability. Further the implementation of the problem-based learning model in teaching and learning process presents problems with real conditions so that it can stimulate students to not only think and understand at the rote level but also interpret the problem. Quiet in-depth research on the implementation of problem-based learning models in learning is highly recommended to get more comprehensive results.

Efektivitas Model Pembelajaran Problem Based Learning pada Materi Asam Basa Untuk Meningkatkan Hasil Belajar Peserta Didik

“…Pendekatan saintifik dalam pembelajaran perlu diperkuat dengan menerapkan model PBL untuk mendorong kemampuan peserta didik menghasilkan karya kontekstual, baik individual maupun kelompok maka sangat disarankan menggunakan pendekatan yang menghasilkan karya berbasis pemecahan. Model problem based learning (PBL) pada mata pelajaran kimia dapat meningkatkan pemahaman konsep dan kemampuan berpikir kritis peserta didik (Uliyandari, 2021).…”

Pengaruh Model Pembelajaran Berbasis Masalah Terhadap Penguasaan Konsep IPS dan Kemampuan Pemecahan Masalah Sosial Murid SD Gugus 3 Kecamatan Kahu Kabupaten Bone

“…(2 tailed) 0,000 untuk penguasaan konsep dan 0,000 untuk kemampuan pemecahan masalah sosial, sehingga dapat disimpulkan bahwa terdapat perbedaan antara siswa yang menggunakan model pembelajaran berbasis masalah dengan siswa yang tidak menggunakan model pembelajaran berbasis masalah terdapat peningkatan kemampuan penguasaan konsep IPS dan kemampuan pemecahan masalah sosial. Seluruh hasil yang peneliti peroleh dalam hal ini menunjukkan kesesuaian dengan penelitian lain sebelumnya yang dilakukan oleh Uliyandari et al (2021) yang menyatakan bahwa terdapat peningkatan kemampuan siswa yang menggunakan pembelajaran berbasis masalah dengan siswa yang tidak menggunakan pembelajaran berbasis masalah. Metode penelitian yang digunakan dalam penelitian tersebut adalah juga quasi eksperimen yang dalam pelaksanaannya menggunakan desain pre-test dan post-test one class atau one group design.…”

The Effectiveness of Using Problem Based Learning and Video Scribe

“…In addition, the use of PBL can also help students develop thinking skills, problem-solving skills, and provide facilities for students to become active, independent, and tough individuals in dealing with problems related to the real world [2]. According to the results of research conducted by Uliyandari [3], the Problem Based Learning model can help to improve conceptual understanding and critical thinking ability of science education undergraduate students. On the other hand, the other researchers show PBL learning model can also increase student motivation to learn by solving the problem [4].…”
