Environmental pollution is a critical issue that requires students to develop strong reasoning and problem-solving skills to understand and address its complexities. However, traditional learning models are not optimal in fostering high-level thinking skills. This study aimed to determine the effect of the PBL-STEM model on deductive, inductive,…

This study aimed to determine the effect of Problem-Based Learning (PBL) integrated Reading, Mind Mapping, and Sharing (RMS) on biological literacy and critical thinking skills in biotechnology material. This type of research is Quasi-Experimental with pre-test-post-test experiments and a control group design. The researcher conducted the research…

Creativity in biology education is a crucial aspect that enhances students' understanding of the subject. It consists of several indicators (fluency, flexibility, originality, and elaboration), which can also be used as measuring tools for creativity. This study aimed to determine the influence of the Problem-Oriented Project-Based Learning…

In the Society 5.0 era, a significant challenge for education is integrating science and technology to strengthen human resources by enhancing students' science competencies. This study aims to develop a PBL e-book that integrates local environmental issues in Bojonegoro, East Java, and to describe its design, validity, and effectiveness in…

The 21st century represents a time of worldwide interconnectedness that demands every individual to have digital knowledge and literacy. Science learning activities are important to help students learn and understand science and students' digital literacy. Learning that actively involves students will encourage students to find ideas. This study…

The purpose of the study is to see if there is a significant difference in chemistry exam achievement growth for 10th grade students in classes with problem-based learning compared with those students in classes with direct instruction. The state in which the study was conducted is developing new standards that are challenging students more than…

This study investigated the effectiveness of the orientation, identify, discussion, decision, and engage in behavior (OIDDE) learning model in enhancing biology learning outcomes, critical thinking, ethical attitudes, and engagement among high school students in Indonesia. Employing a quasi-experimental design with pre- and post-tests, the…

This article explores the possibilities of a cheap one-dollar microscope, the Foldscope, for enhancing out-of-school science education. Developed by Manu Prakash and Jim Cybulski from Stanford University, these origami-type paper microscopes make it possible to provide all students with their own microscopes, due to the low cost. This provides…

In this qualitative study, the researchers explored the ways in which 21st-century skills (specifically communication and critical thinking) are enhanced by Grade 10 beginner Physical Sciences teachers while teaching Particulate Nature of Matter (PNM) through the implementation of problem-based learning (PBL). The study was conducted in one of the…

This study is aimed to investigate the effectiveness of problem-based learning combined with simulation on students' problem-solving and creative thinking skills. By employing a quasi-experimental design, this study used essay and problem-based tests as the instruments to evaluate problem-solving and creative thinking skills of 192 students. These…

Regarding 21st-century learning, scientific literacy is an important competency which must be owned by students. Nevertheless, scientific literacy of Indonesian students has been recognized in low level. This study aimed to describe students' scientific literacy in Bryophyta topic using problem-based learning. This Classroom Action Research (CAR)…

The industrial revolution era 4.0 has now become a major topic in every country. Various sectors respond quickly to this problem, including education. In response to this, there are several aspects of skills that students must master. One of them is problem-solving skills. One of the aspects that influence the students' problem-solving skills is…

Purpose: This study aimed to investigate the potential effects of problem-based learning (PBL), predict observe explain (POE), and PBLPOE on students' problem-solving skills and self-efficacy in Biology. This research is based on various facts that problem-solving skills and self-efficacy of Indonesian students in biology subjects are still low.…

The present study was an attempt to investigate the effect of Problem-Based Learning (PBL), Predict, Observe, Explain (POE), and the combination of both (PBLPOE) on students' critical thinking skills and scientific attitudes in Biology. A pretest-posttest nonequivalent control group design was employed in this study and 132 tenth-grade students…

This paper presents protests from academically successful students who privately conveyed to the researchers their feelings of personal discontent with schools. The criterion to select this "sample" was that these students, dissatisfied with school but having good marks, would reveal what others, academically less successful, could not…
