This study's goal was to learn more about the potential benefits of cooperative PBL on students' metacognitive skills. The systematic literature review (SLR) research design was used for this study, and the requirements were full text, journal articles, open access, accredited national and international publications between 2010 and 2020, and articles on the role of collaborative PBL in chemistry students' metacognitive development. The findings of the SLR used in this study show that PBL enhances students' metacognitive skills, particularly in chemistry students. The majority of research, however, continues to employ unreliable, nonstandard methods. Therefore, it is believed that this research may be used as supplemental data to ac...

However, there is minimal information about the effectiveness of PBL if it is applied with multiple representations (MR) for the students with different learning preferences. This study aimed to prove the effects of problem-based learning strategies (PBL) using multiple representations (MR) and students’ learning styles on the conceptual understanding in chemistry. There were two whole classes in the Mechanical Engineering Department of Bali State Polytechnic that were assigned to be the experimental group (n =59) and control group (n = 58). Felder-Soloman's Index of Learning Style (ILS) was applied to differentiate the students’ learning preferences, while their conceptual understanding in chemistry was assessed using a test after 6 weeks of treatment. The analysis of covariance (ANCOVA) shows that the conceptual understanding...

Quality argumentation skills are formed with the understanding of concepts owned by students. The current low level of argumentation skills is caused by the learning process. Application of guided inquiry learning with the STEM approach is expected to provide space to practice arguments based on the results of the constructs of students' concepts during learning. The results of the study stated that differences in initial abilities, the application of guided inquiry with the STEM approach affect the concepts understanding and argumentation skills of students. Also there is no interaction, between models and learning approaches and initial abilities towards understanding concepts and argumentation skills. Abstrak: Argumentasi merupakan aktivitas penting pada eksplorasi ilmiah yang telah disepakati sebagai komponen utama dalam pendidikan sains. Keterampilan argumentasi yang berkualitas dibentuk dengan modal pemahaman konsep yang dimiliki siswa. Rendahnya keterampilan argumentasi saat ini salah satunya disebabkan oleh proses pembelajaran. Penerapan model pembelajaran inkuiri terbimbing dengan pendekatan STEM diharapkan dapat menyediakan ruang untuk melatih argumentasi berdasarkan hasil konstruk konsep siswa selama pembelajaran. Hasil penelitian menyatakan bahwa perbedaan kemampuan awal, penerapan inkuiri terbimbing dengan pendekatan STEM berpengaruh terhadap pemahaman konsep dan keterampilan argumentasi siswa namun tidak ditemukan adanya interaksi antara model maupun pendekatan pembelajaran dan kemampuan awal terhadap keterampilan argumentasi dan pemahaman konsep.

The three levels of chemical representation can be visualized using flipbook teaching materials so that students are expected to understand the voltaic cell material. Teaching materials are used to support the learning process. Current learning still uses conventional learning models that only focus on teachers. Constructivist-based active learning is needed because it involves students so that learning is more meaningful. One of the constructivist learning models is the guided inquiry learning model which includes observing, asking questions, compiling hypotheses, gathering information, testing hypotheses, and concluding.
