Photoacoustic imaging is a state-of-the-art technique that combines light excitation with ultrasound generation via the photoacoustic effect. Since sound waves at clinically relevant frequencies undergo minimal perturbation as they pass through the body, photoacoustic imaging is ideal for deep-tissue imaging applications in vivo. Despite its…

Drawing is recognized as a powerful tool to learn science. Although current research has enriched our understanding of the potential of learning through drawing, scarce attention has been given to the social-cognitive interactions that occur when students jointly create drawings to understand and explain phenomena in science. This article is based…

Instruction based on active learning is being promoted in higher education by the creation of new collaborative teaching and learning spaces, but capacity does not yet exist for all courses to be held in these new spaces. In this study, we examined how students choose between sections of the same course, with the same materials and techniques used…

The purpose of this study was to evaluate the impact of virtual reality on undergraduate students' self-efficacy, self-concept, interest, and laboratory anxiety in an introductory chemistry course. We used a mixed-methods approach to improve our understanding of how these factors mediate student learning. The findings showed that (i) the use of…

This research aimed to developed an evaluation instrument based on Kahoot! valid, practical, and reliable in evaluating student learning. This research is a model of development that use Borg and Gall. There were seven stages performed, starting with research and data collection, planning, product design development, initial field trials, review…

Photo-oxidation is one of the main causes of oxidative deterioration in food. Understanding of the mechanisms of photo-oxidation is essential for food science students when pursuing careers in food safety and quality assurance. However, few food chemistry laboratories emphasize photo-oxidation. Thus, we develop a laboratory activity that trains…

This paper presents MATLAB user interfaces for two multiphase kinetic models: the kinetic double-layer model of aerosol surface chemistry and gas--particle interactions (K2-SURF) and the kinetic multilayer model of aerosol surface and bulk chemistry (KM-SUB). Each interface has simple and user-friendly features that allow undergraduate and…

Research has shown that student access and achievement in advanced precollege chemistry has been largely inequitable when considering certain demographic factors. In this nonexperimental observational study, an intersectional analysis of ethnicity and gender was utilized to examine United States student participation and performance (N = 146,610)…

To potentially engage students in "doing organic chemistry", organic chemistry courses should foreground weaving together structure- and energy-related ideas to construct causal accounts for phenomena. Here, we investigate whether enrolling in an organic chemistry course that places substantial emphasis ([approximately]50% of total…

Organizing undergraduates in chemistry, energy engineering, and chemical engineering specialties to participate in an energy transformation experiment can encourage them to think about the impact of human activities on nature and stimulate them to learn more about the topic. This laboratory experiment demonstrates a general approach to the…

We here propose a simple and fast hands-on activity requiring limited equipment, to introduce students of various levels (bachelor's or high school) and backgrounds (from science to arts) to the chemistry of color. The different colors of stained glass are replicated through the deposition, on ordinary glass slides, of silica coatings colored by…

Formative assessments (FAs), such as muddiest point activities can capture students' areas of confusion or struggle on given content that may otherwise be overlooked with the common FAs, such as quizzes, homework, and clickers. The few reported studies indicate mixed results on the effects of implementing the muddiest point in undergraduate STEM…

Entrepreneurship is a teachable issue, and certain educational approaches can affect the entrepreneurial performance of learners. The purpose of this study was to investigate the effect of education with the science, technology, engineering, and mathematics (STEM) approach on the development of the entrepreneurial thinking skills of students who…

Organic chemistry courses enroll students from many majors with diverse interests. Although instructors may strive to appeal to these interests by relating course content to real life, it is challenging to intrinsically appeal to students at the personal level, particularly in high enrollment courses like organic chemistry. When students identify…

Chemistry educators around the world have had to introduce innovative approaches for engaging students through virtual chemistry laboratory exercises, both out of necessity and to complement traditional in-person learning. As new methods are explored, instructors strive to offer experiences that are engaging and accessible and that foster skills…
