Abstract The teaching of problem-based learning is a didactic approach that requires a radical change in the role of the physics teacher because it is focused on learning, research, and reflection that students follow to reach a solution to a problem situation as a starting point for the acquisition and integration of knowledge in science. The results of a training action for physics teachers on the implementation, their perceptions, and perspectives on the feasibility of the problem-based Learning approach are presented. The study is quasi-experimental in nature with pre-test and post-test in the study variables. The results suggest that the teachers’ perceptions are positive, which is why they consider that its implementation in teaching is viable, however, they need more elements that facilitate their execution in the classroom, such as understanding the theoretical foundations and their pedagogical use successful in the classroom. It is concluded that, for the physics teaching process, problem-based learning is an innovation because it allows the student to learn actively, in which inquiry is relevant for the development of skills and appropriation of knowledge, which in the framework of natural sciences leads to the reconstruction of the scientific method.

The ability to solve problems is a skill that students need to have in dealing with various problems in life. This study aims to determine the effect of problem based learning models; cognitive styles and interaction between both factors on science learning outcomes of students in class VII of MTs 2 Tanjung Jabung Timur in academic year 2015/2016. This research was conducted with a quasi-experimental research method by applying a 2 × 2 factorial design. The study sample consisted of an experimental class of 30 students and a control class of 29 students. Data collection was conducted using two types of instruments, namely the Group Embedded Figures Test (GEFT) to measure students cognitive styles and students' learning outcomes test in essay forms. The Problem Based Learning model affect the learning outcomes, there is significant difference in science learning outcomes between students who have Cognitive field dependent (FD) style that is taught by the Problem Based Learning model and students who have Cognitive FD style that is taught by conventional learning models. The results show that the value of the experimental class post-test is higher than that of the control class. In short, the experimental class with the application of the Problem Based Learning model in the learning process provides higher learning outcomes than that of the conventional models.

We aimed to contribute to a shift in higher education teaching and learning methods by considering problem-based learning (PBL) as an approach capable of positively affecting students from a geology and environment (GE) curricular unit. In a convenience sample from a Portuguese public university, two groups of students were defined: (1) an experimental group (n = 16), to which an intervention program (IP) based on PBL was applied, and (2) a comparison group (n = 17), subjected to the traditional teaching approach. For nine weeks, students subject to the IP faced four problem scenarios about different themes. A triangulation of methods was chosen. The study involved two phases: (1) qualitative (sustained on content analysis of driving questions raised by students, registered in a monitoring sheet) and (2) quantitative (quasi-experimental study, based on data from a prior and post-test knowledge assessment). The qualitative results point to the development of more complex cognitive-level questioning skills after increasing familiarity with PBL. The data obtained in the quantitative study, which included both a “within-subjects” and a “between-subjects” design, show higher benefits in the experimental group, documenting gains in terms of scientific knowledge when using the PBL methodology.

Chemistry is one of the scientific disciplines considered difficult for students to understand its microscopic and macroscopic concepts. Students also claim that this discipline is tedious and complicated. They are unable to connect what is shown in the visual structure to the process and phenomenon. In the context of self-motivation among university students, there is a higher chance of expanding the stimulation of learning. This study aimed to improve self-confidence and the mastery of concepts of chemistry teaching students using problem-based learning. The quasi-experimental method was used with the design of the non-equivalent pre-test-post-test control group. The population included all students in the electrochemistry class at Lampung University in 2019. The purposeful sampling technique employed divided the sample into two groups. The first group was called Class A and was considered as the experimental class - using problem-based learning -. The second group, Class B, was recognized as the control class - using the conventional model in which the teacher applied the speech method in the delivery of materials during the class -. Class A's self-confidence and mastery of concepts have a higher nGain value than class B, and the result of the effect size is that class B has a more significant effect than class A. Based on the outcome, one can conclude that problem-based learning has a significant influence on improving self-confidence and mastery of concepts on the electrochemical theme.

Terdapat banyak model pembelajaran yang diterapkan untuk menganalisis kemampuan argumentasi ilmiah siswa. Namun, belum banyak model yang diintegrasikan dengan pembelajaran berbasis simulasi online untuk meningkatkan kemampuan argumentasi ilmiah siswa. Padahal, saat ini ada banyak website simulasi online yang diterbitkan oleh lembaga pendidikan atau universitas di tingkat internasional dan jarang digunakan dalam penelitian. Penelitian ini mengintegrasikan model pembelajaran inovatif dengan pembelajaran berbasis online simulation untuk meningkatkan kemampuan argumentasi ilmiah siswa. Website simulasi yang digunakan adalah Edu-media simulation. Dalam website ini ada banyak simulasi fisika yang disediakan, tetapi belum banyak penelitian yang menerapkan simulasi ini. Penelitian ini dilakukan dengan kuasi eksperimen yang terdiri dari satu kelas eksperimen dengan sampel 25 siswa kelas XI MIA 3 di SMA N 1 Prambanan Yogyakarta. Argumentasi ilmiah siswa diukur melalui instrumen tes uraian. Data argumentasi ilmiah siswa dianalisis menggunakan paired sample t-test  dan pola argumentasi Toulmin (TAP). Hasil penelitian menunjukkan bahwa PBL berbantuan edu-media simulation dapat meningkatkan kemampuan argumentasi ilmiah siswa baik secara kuantitatif maupun kualitatif. Ini ditunjukkan dengan nilai t value -11.051 < -1.711 bahwa terdapat perbedaan nilai rata-rata argumentasi pada pre-test (17) dan post-test (47). Dalam hal ini, siswa sudah mampu membuat klaim yang tegas dengan menyajikan bukti dan alasan yang mendukung klaim. Analyzing students’ scientific argumentation skill in optic: Problem-based learning assisted edu-media simulation AbstractThere are many learning models applied to analyze the ability of students' scientific argumentation. However, not many models have been integrated with online simulation-based learning to improve students' scientific argumentation skills. In fact, there are currently many online simulation websites published by educational institutions or international universities and rarely used in research. This research integrates innovative learning models with online simulation-based learning to improve students' scientific argumentation skills. The simulation website used is Edu-media simulation. In this website there are many physics simulations provided, but not many studies have applied this simulation. This research was conducted with a quasi-experimental consisting of one experimental class with a sample of 25 XI MIA 3 graders in Prambanan High School 1 Yogyakarta. Students' scientific arguments are measured through a description test instrument. Students' scientific argumentation data were analyzed using paired sample t-test and Toulmin argumentation patterns (TAP). The results showed that PBL assisted by edu-media simulation can improve students' scientific argumentation ability both quantitatively and qualitatively. This is indicated by the value of t value -11.051 <-1.711 that there are differences in the average value of argumentation in the pre-test (17) and post-test (47). In this case, students have been able to make assertive claims by presenting evidence and reasons that support the claim.

This study investigates the effects of problem-based learning (PBL) on students' academic achievements in studying ‘Electrochemistry’ within a course on Analytical Chemistry. The research was of a pretest–posttest control group quasi-experimental design and it was conducted with second year students in the Chemistry Teaching Program at the Faculty of Education at Dokuz Eylul University. The topic was taught with PBL in the experimental group and with expository teaching strategies in the control group. The ‘Chemistry achievement test (CAT)’ was applied as the pre-test and post-test in both groups. Post-test scores from the CAT demonstrated that there was a significant difference between the academic achievements of the two groups in favour of the experimental group (U= 8.500,p< 0.05). After using PBL for a period, eleven open-ended questions related to the topic were asked to both groups. The results of these questions were categorized and the scores obtained from the categories were evaluated using content analysis. The results of the scores obtained from the open-ended questions showed that the students in the experimental group were able to make statements containing fewer misconceptions and also had a better understanding of this topic when compared to the students in the control group (U= 2.500,p< 0.05). The correlation between the scores in the CAT post-test and the scores obtained from the open-ended questions of the experimental and control groups was also examined. The Spearman correlation coefficients were found to be 0.907 and 0.595 for the experimental and the control group, respectively. This finding indicated that there was a positive and very high level of statistically significant correlation between the scores in the CAT post-test and the scores obtained from the open-ended questions of the students in the experimental group. Therefore this finding also supports the conclusion that the students in the experimental group were better able to understand the topic and its structure compared to the students in the control group. At the end of the application, the results of semi-structured interviews carried out showed that students in the experimental group had positive opinions regarding PBL.
