Knowledge of scientific principles and practices is vital to creating informed citizens. At its core, science helps create citizens who question the why and how of things, while also increasing knowledge of the world and beyond. Humans by nature are curious and thrive when they are engaged in learning that relates to real-world situations relevant…

This meta-analysis evaluated the effectiveness of inquiry-based learning (IBL) on improving students' conceptual understanding in science and mathematics. The study systematically reviewed 12 empirical studies with 14 effect sizes involving 786 students across various countries, educational levels, and disciplines. These studies were selected…

This study aimed to investigate the effects of the prediction-observation-explanation (POE) strategy using worksheets designed for the "living things and life" topic on conceptual understanding and science process skills (SPS) of students with mild intellectual disabilities (SMIDs). The sample consisted of 12 SMIDs (eight students for…

Future needs and challenges, especially in complex real-world problem-solving, require education to equip individuals with quality skills. Inquiry-based learning that integrates socio-scientific issues (SSI) can significantly develop students' problem-solving skills. This study aims to test the effects of the Socio-Scientific Real-world Inquiry…

This research investigated the effect of project-based learning (PjBL) on students' conceptual understanding of mechanics. For this purpose, a quasi-experimental research design was conducted with 50 ninth-grade students at Nazarbayev Intellectual School in Kazakhstan. We used the force concept inventory test to measure students' conceptual…

Clearly defining and clarifying crosscutting concepts (CCCs) helps students to apply them as thinking tools or lenses to understand disciplinary core ideas and science and engineering practices. This study identified three characteristics of the sub-concepts of CCCs: conceptual, superordinate, and common across disciplines, and explored a way…

In science education, students need to work with laboratory elements that create conditions for them to learn to do science and experience the value of making meaning in this process. However, students rarely get to carry out investigations that resemble actual scientific practices. More often, they are encouraged to follow an already given…

Anaerobic respiration reactions are of fundamental importance to global biogeochemical cycling of elements. Yet, the idea that cellular respiration can occur not only in the absence of oxygen but also involve the oxidation of inorganic substrates (e.g., AsO[subscript 3 superscript 3-], Fe[superscript 2+], H[subscript 2], H[subscript 2]S,…

Argumentation skills are important for students to analyze and evaluate critical information, especially in complex science issues. Socio-Scientific Real-world Inquiry [SSRI] learning helps students develop deep scientific understanding and the ability to build evidence-based arguments in a real context. This study aimed to examine the…

This study delves into the realm of student conceptual change, examining shifting understandings as important steppingstones on the path to sensemaking and canonical understanding in science education. It explores the potential of a STEAM (Science, Technology, Engineering, Arts, and Math) curriculum, aiming to provide equitable learning…

Acid-base physiology is widely recognized as one of the most conceptually challenging topics in undergraduate education due to its interdisciplinary nature and the necessity for both mechanistic and integrative understanding. This article presents a structured, system-based teaching framework designed to enhance student comprehension of acid-base…

The movement of air into and out of the lungs is facilitated by changes in pressure within the thoracic cavity relative to atmospheric pressure, as well as the resistance encountered by airways. In this process, the movement of air into and out of the lungs is driven by pressure gradients established by changes in lung volume and intra-alveolar…

The concepts of bacteriology are still poorly understood by students of the Department of Biology Education, Mulawarman University. Certain ethnic characteristics influence student learning processes and outcomes. A quasi-experiment was carried out at the Department of Biology Education, Mulawarman University in the even semester of the 2022/2023…

An effective, practical approach for incorporating molecular biology tools to biology and biochemistry students is described. For 6 weeks, students are exposed to bacterial transformation, plasmid DNA purification and analysis, parasite transfection, ectopic expression of fluorescent proteins, fluorescence microscopy, and flow cytometry analysis.…

This research explored kindergarten students' learning of simple particle models to explain the properties and behavior of matter in the solid, liquid, and gas states and during phase transitions (evaporation, melting, freezing, and condensation). Science instruction for young learners tends to focus on the concrete and directly observable. This…
