A comprehensive teaching experiment plan tailored forthird-yearundergraduates has been developed. Initially, instructors synthesize(E)-2-(4-((4-(2-hydroxyethoxy)-3-methylphenyl)­diazenyl)­phenoxy)-ethan-1-ol­(M-Azo-2)monomer as part of the preclass preparation. Subsequently, studentsperform an acylation reaction experiment to prepare an…

This study aimed to develop an instrument with acceptable validity and reliability for assessing two key aspects among science teachers: their self-efficacy in teaching science through an integrated STEM approach (STSIS) and their outcome expectancy when employing this approach (OETSIS), which we refer to as TSTSIS. We administered this tool to…

A new undergraduate thin-layer chromatography laboratory experiment devoted to quantitative determination of disulfiram in Anticol formulation is presented. The proposed activity can be a part of a chromatographic methods of analysis course as well as a general chemistry course. To carry out a quantitative analysis, an image analysis technique was…

Most students enter college without any exposure to polymer science, which leads to the poor understanding and slow implementation of plastic recycling programs in the United States. To address the knowledge gap in chemical recycling, we introduce a 2-part laboratory experiment that was conducted in multiple high schools and public outreach events…

Cultivating students' enjoyment of science is one of the significant aims of science education. However, it seems challenging to achieve this goal in most countries or economies. Using the Trends in International Mathematics and Science Study (TIMSS) 2019 Hong Kong data, this study aims to identify multiple configurations of school conditions to…

Many undergraduate chemistry and biochemistry students pursue careers in healthcare. Biomaterials, designed to harmonize with the complexity of the human body, have become increasingly significant in medicine as implants, drug delivery vehicles and tissue scaffolds. We believe it is essential that undergraduates are exposed to biomaterial…

Although the present university-level chemistry experimental curriculum has been extensive and well-designed, it lacks a connection with the scientific research field, especially the frontier field. It is crucial to incorporate recent discoveries through new experiment designs to bridge this gap and boost the value of the undergraduate…

The substitution of carbonyl compounds with liquid bromine as a brominating agent is the most commonly employed synthesis method for a-bromoacetophenone and its derivatives. However, liquid bromine possesses certain drawbacks, such as volatilization, high toxicity, strong corrosion, and poor reaction selectivity, which limit its application and…

Owing to factors such as poor water solubility of luminol and the instability and easy decomposition of hydrogen peroxide (H[subscript 2]O[subscript 2]), the accuracy and sensitivity of the detection of H[subscript 2]O[subscript 2] through the luminol electrochemiluminescence (ECL) system are limited. Herein, we propose a water-soluble…

Course-based undergraduate research experiences (CUREs) provide students with valuable opportunities to engage in research in a classroom setting, expanding access to research opportunities for undergraduates, fostering inclusive research and learning environments, and bridging the gap between the research and education communities. While…

Sustaining a broad diversity of plants is key for a sustainable future. For instance, providing a variety of flowering plants in urban and agricultural landscapes mitigates the current decline of pollinators and biodiversity in general. Therefore, educating about the diversity of flowering plants has high current relevance for biology and…

Teaching science in an age of disinformation and misinformation requires empowering students to address inaccurate information in evidence-based ways. Science communication scholarship highlights the growing importance of inclusive and relational approaches for addressing misinformation. Thus, we developed, implemented, and evaluated an…

Increasing student engagement with the social practices of science (i.e., communication, collaboration, and critique) is a goal throughout K-16 science education and provides an opportunity for science educators to leverage student discourse to optimize learning. Yet how instructors can encourage forms of discourse which predict increased…

A community-engaged learning experiment was developed for an introductory analytical chemistry course at the University of Toronto Scarborough in collaboration with Campus Farm. The experiment introduced students to the application of analytical techniques to studying environmental samples. More specifically, students investigated the potential of…

Kids are drawn to dolls and dump trucks, and crashing the two together might just be a child's favorite pastime. Who knew such a simple pleasure could serve as an accessible, compelling phenomenon for instigating investigations of force and motion. With a few inexpensive materials straight out of the toy box (literally, a doll, a dump truck, a…
