The COVID-19 pandemic posed significant challenges for practical teaching within the sciences. While many instructors adopted innovative alternatives to conventional practicals, many relied on digital approaches that did not give students hands-on experience. In this study we evaluate the use of 'at home' practical kits used in first year physics…

Exposure to nature can improve mental health and cognitive abilities, while creating enhanced engagement with biological course material through interactions with organisms and ecosystems. Remote biology education was suddenly implemented during the COVID-19 pandemic at many universities, and such distance education continues to provide broadened…

Science, technology, engineering, and mathematics (STEM) education has become a focal point of global discussions in the field of education. It emphasizes an interdisciplinary approach to learning. Subjective well-being of adolescents is characterized as joy to learn, close connectedness in schools, perception of the purpose of education, and the…

Green chemistry provides unique opportunities for student engagement through K-12 and community outreach. As a platform for safe, engaging outreach, green chemistry activities allow for hands-on approaches to introducing science and chemistry concepts in informal settings. Green chemistry outreach also is a means for American Chemical Society…

The use of unsafe water as a source for drinking, cooking, and bathing can lead to serious health complications. Point of Use (POU) water treatment technologies can play an important role in making safe and clean drinking water available to communities. One low-cost, low-technology POU system is the biosand filter (BSF). BSFs offer an effective…

As an outcome of multidiscipline integration, the polymeric surfactant is of growing importance in modern industry and scientific research. However, the instructional introduction on polymeric surfactants is still insufficient in universities nowadays. In order to effectively guide undergraduates to study polymeric surfactant, a new polymeric…

The Gatsby "Good Practical Science" report (Gatsby, 2017) identified opportunities to carry out open-ended investigative projects as one of ten benchmarks for good practical science. However, there is currently no requirement for post-16 students in England to have access to such opportunities as this is not required by A-level…

Students have several misconceptions about thermodynamics. However, an understanding of basic concepts in this branch of physics remains fundamental to explain thermal phenomena. The purpose of this activity was to extend students' conceptual understanding of heat, temperature, energy, and thermal insulators and conductors. Two groups of students…

Oxygen reduction reaction (ORR),as a multielectron electrode reaction, is an important electrochemical reaction in the field of electrochemical energy storage systems. Herein, a new advanced electrochemical laboratory experiment is designed for undergraduates to master the preparation of oxygen reduction catalytic electrode. Students can use…

As a result of the COVID-19 pandemic, many courses were forced online. This posed particular challenges for courses with laboratory or hands-on components. A group of instructors at the University of Minnesota and the University of Wisconsin-Madison designed an online, asynchronous course structure for teaching introductory horticulture courses…

Exploding pumpkins with rubber bands remains a popular demonstration of the conversion of spring potential energy into kinetic energy. Videos of laughing and squealing children and adults being pelted with pumpkin fragments have millions of hits on YouTube, and the activity has even been featured on talk shows like "The Tonight Show Starring…

Introduction: Early informal learning experiences are essential for sparking long-term interest in science, technology, engineering, and math (STEM). In a prior study, we found more promising parent involvement outcomes when families of young children were provided with STEM family education events along with home STEM activity kits compared to…

Background: Over the past three decades, researchers have increasingly advocated for pedagogical practices that privilege exploration, collaboration, problem-solving, and hands-on projects in K-12 Science, Technology, Engineering, and Mathematics (S.T.E.M.). Many researchers have studied the efficacy of these instructional practices, but there has…

The objective of this research was to examine the impact of STEM activity based on DIY, Tinker and Maker frameworks on developing teacher interns' competency in science instructional design and implementations. These activities involve the integration of science, technology, engineering, and mathematics principles, fostering self-regulated…

The study explored science teachers' perceptions of Scientific Investigations (SI) and their classroom practices in South Africa. An explanatory sequential design using qualitative and quantitative approaches was used. Qualitative data were collected first using interviews and classroom observations, followed by quantitative data using a…
