Electrochemical characterization techniques are essential for studying and developing advanced materials across various fields, from corrosion science to energy storage, photovoltaics, and bioelectrochemistry. However, these techniques are often under-represented in educational curricula. This practical guide with a hands-on laboratory experiment…

Empowering students with a robust Science, Technology, Engineering, and Mathematics (STEM) education, while equipping their teachers with comprehensive training, fosters critical thinking and problem-solving skills, which are important aspects of innovation, social progress, and advancement. The main objective of this study is to investigate how a…

In this article I explore the case of the Mariana dam disaster in 2015 in Brazil seeking to contribute to reflections about the role of chemistry and chemistry education in environmental injustices. Drawing on stories about this disaster shared in the Dead River Podcast (2024), on wider literature and on other cases of environmental injustices…

Writing is important for science, technology, engineering, and math (STEM) graduate students to achieve milestones within their programs and for their future career aspirations. However, although STEM graduate students engage in a variety of academic writing activities in their time as doctoral students, writing development has not always been a…

Integrating new synthetic methods and experimental techniques from the latest research reports into undergraduate laboratory experiments is of great significance, as it enables students to learn the cutting-edge technology of organic chemistry and cultivates their experimental skills and innovative thinking. In this study, an experiment on their…

Digital badges are credentials earned via a digital presentation to demonstrate the mastery of a technique. They have been utilized in General Chemistry laboratory courses as an assessment tool and to document students' development of a skill. A digital badge assignment was developed for thin layer chromatography (TLC) and integrated into a…

Appealing to students' affect in academic settings, such as demonstrating chemistry's relevance to their life, is one strategy instructors may use to support students' in learning. This study investigates the types of connections that students make to organic chemistry when responding to an open-ended writing assignment. Students enrolled in an…

Prior research suggests most students do not glean valid cues from provided visuals, resulting in reduced metacomprehension accuracy. Across 4 experiments, we explored how the presence of instructional visuals affects students' metacomprehension accuracy and cue-use for different types of metacognitive judgments. Undergraduates read texts on…

The purpose of this study is to "meta"-analytically evaluate research that used chemical bonding-based interventions to improve academic performance. Through "meta"-analysis, the present study used several keyword patterns (e.g., chemical bonding, experimental, chemistry education, science education) via relevant databases…

University courses are often interconnected; however, the connections between these courses remain unclear to many students. This is particularly important in the field of forensic science since each stage of the investigation, from the crime scene to the courtroom, has significant implications on the outcome of a case and the individuals…

According to several studies, the three levels of representation in chemistry are the fundamental aspects of effective learning and understanding of chemistry. In this study, we aim to illustrate how students identify changes in the matter using eye-tracking and verbalizations. Five students observed chemical and physical phenomena depicted by…

A multicomponent reaction was adapted and successfully applied in the major organic course, which involves synthesizing and characterizing a 1,3-benzoxazine derived from paracetamol extracted from tablets of the worldwide well-known medicine Tylenol. Using paracetamol as a reagent is a motivational strategy in undergraduate laboratories to meet…

Despite representations' central role in conveying chemical phenomena, mastering them is not trivial, given the wide variety of different conventions to interpret and use them. Furthermore, instructional approaches and materials may overlook explicit discussion on how students should reason with representations. To gather evidence that could guide…

A mixture of salt water and isopropyl alcohol is immiscible, forming two separate liquids with the organic layer on top and aqueous layer on bottom. When universal indicator is added to such a mixture, all of the indicator compounds in the universal indicator preferentially dissolve in the alcohol--except for phenolphthalein at high pH. Mixtures…

Given the severe pollution caused by traditional plastics, biodegradable plastic products (BPPs) have received great attention and are appearing in people's lives in the form of packaging bags, tableware, etc. Whether a wide variety of BPPs can truly degrade depends on the environment. Aerobic composting is the arbitration method to evaluate the…
