This study aimed to examine the impact of years of experience and field of expertise on the development of chemistry knowledge structures from STEM experts comprising 103 professors, 10 postdocs, and 146 doctoral students. Of these participants, 127 were specialized in chemistry and the rest were from various science and engineering disciplines.…

Undergraduate organic chemistry laboratory courses act as a baseline for introductory scientific experimentation. These courses provide students with the knowledge and skills for their future careers. The traditional lab is conducted by providing a structured protocol of the experiment for the students to follow and reproduce the assigned task…

Recently, two-dimensional (2D) nanostructures, such as graphene and few-layer MoS[subscript 2], have been applied to wide fields based on their intriguing performances, and they contribute to developments of clean energy, biomedicine, and environmental protection. The synthesis of 2D nanostructures involves chemistry, materials, and…

Fieldwork is a meaningful and authentic learning experience that is rarely included in undergraduate chemistry courses. In this laboratory, we visited a hot spot of perfluoroalkyl acid (PFAA) contamination identified in 2012, in Binbrook, Ontario, Canada, a 1 h drive from the University of Toronto. The persistence and unique environmental…

Highlighting the interdisciplinary nature of research, we present a series of experiments for undergraduate lab courses that teach the principles of preparative ion exchange chromatography and flame emission spectroscopy. Through these inquiry-based experiments, the students learn about experimental design and instrument limitations, naturally…

Efforts to understand changes in teacher curricula following the adoption of reform-based standards, such as the "Next Generation Science Standards" (NGSS) remain incomplete and prior scholarship has identified several topics in the standards (e.g., nuclear chemistry and kinetics) that remain infrequently addressed in teachers'…

This study was an action research self-study that examined my role as a teacher educator supporting a resident teacher in learning how to design inquiry-based culturally responsive science lessons. I explored my own growth in understanding how to act as a teacher educator to provide appropriately scaffolded support to promote learning for a…

This paper is part of the special issue on Teacher Learning and Practice within Organizational Contexts. Shifting instructional practices in elementary schools to include more equitable, reform-based pedagogies is imperative for supporting students' development as science learners. Teachers need high quality professional development (PD) to learn…

Language is a fundamental tool for learning science. This study highlights the importance of teacher knowledge in utilising language as a tool for knowledge generation in the classrooms. This case study examines elementary teachers' development of declarative, procedural, and epistemic knowledge related to using language, particularly focusing on…

One way to preserve culture in education is through ethnoscience-based learning, especially in chemical materials linked to various fields of science in life, including social and cultural. Ethnoscience is a process of reconstructing indigenous science knowledge with scientific science. This research aims to explore trends in ethnoscience-based…

Anatomy, physiology, and pathophysiology are essential foundational concepts of nursing education. Despite consensus on the importance of the bioscience curriculum, teaching and learning challenges persist without widely recognized strategies to address the obstacles. 3D virtual cadavers are a promising technological resource to improve bioscience…

This study developed a phenomenographic argument regarding science teacher educators' (STEs) question-asking conceptions. Question-asking in teaching how to teach science concepts to prospective science teachers is a fundamental strategy. However, STEs' conceptual understanding of the question-asking phenomenon is uncharted territory. The present…

This paper presents an innovative teaching approach that integrates photoelectric technology with analytical chemistry instruction through inquiry-based learning (IBL), using cerium as a selected analyte. With the advancement of science and technology, a strong foundation of basic knowledge and methodologies is crucial in analytical chemistry…

The purpose of this study is to examine the effects of employing an augmented reality (AR) lens imaging system on inquiry-based learning concerning junior high school students' science achievement, science learning motivation, and inquiry skills. For this purpose, an AR lens imaging learning system was developed specifically for the lens imaging…

Interdisciplinary thinking is critical for equipping students to apply scientific knowledge and tackle societal challenges across various disciplines, which has been recognized as a key objective of twenty-first century science education. However, research on effective interdisciplinary assessment in secondary school science education is still…
