Understanding teachers' experiences as they lived them and as they told them is important for conceptualizing a well-rounded view of the state of science education and the role teachers play in it. Journey mapping, a way of visualizing one's processes and experiences as they progress towards a goal, is a tool with the potential to capture…

Machine learning (ML) is extensively applied in chemistry, particularly in vibrational spectroscopy. However, few teaching examples effectively demonstrate the capabilities of ML in classifying polymeric materials, exhibiting subtle spectral differences that elude visual discrimination. This study presents a teaching example specifically tailored…

Field-Based Practicum (FBP) about Pterydophyta diversity material in Low plant botany learning is very important, even though the facts in the field show that FBP is still minimally carried out. This research aims to utilize the potential diversity of Pterydophyta in the Tuban-Lamongan Pantura area as a support for FBP about low plant botany…

This study investigates preschool teachers' considerations for including digital tools in science teaching to develop children's learning of science content. Due to the ongoing digitalisation and demands in society, the utilisation of digital tools has increased significantly in educational settings. Recent research about digital tools in early…

Studies of both professional science practice and children's science learning show that care is not merely ancillary to disciplinary work but a core and generative constituent of science practice. In science education research, however, students' care is often overlooked. In this paper, we describe the expression of care across two STEM classrooms…

Inquiry-based instruction has played an important role in science education, and been recognized as a critical approach to improve students' scientific learning effectiveness. However, current research revealed that it is a challenge for teacher education programs to improve pre-service science teachers' inquiry-based instructional activity design…

This study examined the early implementation stages of the Modeling Method of Instruction (MMI) in the science classroom to find the most valuable strategies for effective implementation. In this qualitative study, eleven teachers were interviewed to uncover effective implementation strategies. Interview data were analyzed using the constant…

Dissertation objectives included investigating how environment and plant life history influence aspects of leaf vascular infrastructure that supports photosynthesis, as well as photoprotection of the photosynthetic process. Additionally, I aimed to engage students in science and plant biology through innovative teaching methods. In summer annual…

Here we demonstrate how data from the clinical pulmonary function lab can help students learn about the principle of airway-parenchymal interdependence. We examined the relationship between airway conductance (Gaw) and lung volume (thoracic gas volume, TGV) in 48 patients: 17 healthy; 20 with emphysema, expected to have reduced airway-parenchymal…

Chemistry experiments involving biological aspects are in high demand. This laboratory exercise blends biochemistry and physical chemistry, illustrates key concepts of the virus capsid surface, and is designed for a chemistry laboratory course for students majoring in biology in college. The experimental part provides a mastery of…

Analysis of results from research in cognitive science and discipline-based education in recent years suggests that student thinking and learning can be better understood and investigated by adopting a systemic perspective that recognizes the complex and dynamic interactions taking place within and across multiple interconnected and interdependent…

This study investigates alternative conceptions of chemistry concepts among Faculty of Science students at Palestine Technical University-Kadoorie. Students are found to have incorrect views about fundamental chemistry concepts. The study aims to identify these misconceptions, understand their origins, and their impact on students' comprehension.…

Forces and motion are at the heart of physics and children start learning from the moment they are able to interact with the world. Children as young as one year show surprise when a ball does not behave as expected. This is a tremendous bonus to learning physics, but it has hidden dangers: they only learn how things move on the Earth, where we…

The amount of protein in complex matrices such as food products is an important characteristic, at both a nutritional and a pedagogical level. There are several methods available for protein quantification, from simple UV absorption to mass spectrometry. The most common are based on the interaction of the proteins with colored compounds followed…

The mercury beating heart is a classic demonstration to introduce redox reactions in the classroom. Here we report a new, safer demonstration: the Galinstan beating heart. Galinstan is a commercially available eutectic alloy composed of gallium (68.5%), indium (21.5%), and tin (10%) that has low toxicity. When an iron nail touches the Galinstan…
