When teaching STEM courses, it is important to introduce state-of-the-art techniques. Students need to learn how to conduct experiments, analyse data and choose the most effective approaches to address meaningful situations. Here we present the assessment of the implementation of a structured inquiry-based activity aimed at teaching students about…

The ability of students to perform quantitative analysis is a fundamental aspect of analytical chemistry courses and laboratories. In this laboratory experiment, students quantitatively analyze both liquid and solid samples through the use of internal standard calibration and ATR-FTIR spectroscopy. Using a problem-based approach to selecting their…

The aim of this study is to examine the effect of the science module which was designed using the problem-based learning method on the basis of the Integrated Curriculum Model and applied in the blended learning environment on the scientific reasoning and scientific process skills of gifted students. The study was carried out with 9 gifted 5th…

Students in Indonesia still have the low level of scientific argumentation skills. This study purposed to examine the impact of Problem-based Learning (PBL) with Argument Mapping and Online Laboratory in improving the scientific argumentation skill. It describes the significance of the differences between participants who learn through PBL, PBL…

Student science proficiency development demands sustainable and coherent learning environment support. Scholars argue that project-based learning (PBL) is an efficient approach to promoting student science learning, compared to conventional instructions. Yet, few studies have delved into the learning process to explore how a coherent PBL system…

This was second year's research in developing a biology learning module of ecosystem material that promotes mobile android-based local region potentials, after first year conducted a field examination on android e-module and limited testing in East Lombok Regency, West Nusa Tenggara and Sleman Regency, D.I. Yogyakarta. The second-year research…

How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

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…

This study aimed to examine the effect of problem-based learning (PBL) in developing science process skills (SPS) and learning achievement on the topic of 'Safety in Our Environment' in secondary schools in Tanzania. The study employed a quasi-experimental design. The participants for the study were Form One 'Stream E' students in the experimental…

This study was conducted in order to analyze the relation between analytical thinking skill and scientific argumentation in physics learning. The study was conducted with the interactive CK 12 simulation about optics. The sample of the study consists of 28 randomly selected students in Yogyakarta, Indonesia. The data was collected using pre and…

This study aims to explore the literature on learning interventions that can enhance students' multiple representation skills and identify indicators for assessing multiple representation abilities in physics education. Following the PRISMA procedure, the research is a systematic literature review using qualitative content analysis techniques. The…

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…

Small-group activities play a crucial role in biology education, fostering active learning, teamwork, and critical thinking. While their benefits are well-documented, there is a need for innovative classroom exercises that provide students with a real-world perspective on biotechnology and pharmaceutical industries. This paper introduces a…

A Sonogashira experiment was transformed into a problem-based learning platform for third-year undergraduate students. Given a target that could be synthesized in a single step, students worked in groups to investigate which method was the best for large-scale production. Through this practical scenario, students learn to conduct a literature…

Problem-based learning (PBL) is an acclaimed educational concept for laboratory teaching in chemistry, which significantly affects learner motivation. A central aim of PBL is to overcome educational problems with "cook-book" laboratories. For example, when students receive experimental instructions and apply the instructions similar to…
