Lock-in amplifiers (LIAs) are commonly used in chemistry laboratories to improve noise-to-signal ratios. Constructing and testing a suitably designed LIA provide undergraduate students with an excellent opportunity to learn about theory, construction, and applications of LIA. In particular, students can learn about time-dependent behavior and…

The number of online courses offered by universities in America continues to increase. Due to limited direct interactions with students, these courses can struggle to promote student engagement. Food science is uniquely situated for implementation of hands-on project-based learning opportunities since basic experiments can be performed in a…

This paper introduces quantum materials and the notion of using models to aid the comprehension of complex ideas. It describes a hands-on activity, collaboratively developed by scientists and artists, that promotes an understanding of how experts take advantage of analogical thinking and model building to develop important frameworks. Quantum…

We are writing in response to the Aditomo and Klieme article titled "Forms of inquiry based science instruction and their relations with learning outcomes: evidence from high and low-performing education systems," recently published in the "International Journal of Science Education." In this essay, we follow these authors and…

Few laboratory exercises exist that introduce undergraduate students to both the concepts and instrumentation used in rotational spectroscopy. Because of this gap in undergraduate laboratory training, a teaching laboratory for the pure rotational spectroscopy of benzonitrile has been developed and reported. Owing to benzonitrile's recent discovery…

"Chemistry in the Public Library" is an outreach event that has fostered a continuing, long-standing partnership between The Evergreen State College in Olympia, Washington (a public, liberal arts college), the Olympia Timberland Regional Library (the local public library), and the community. It started as a National Chemistry Week event…

In 2018-19, Dr. Guirong Wang, from Beijing University of Chemical Technology, spent a year with the Centre for Industry Education Collaboration (CIEC). CIEC has been involved in world-class outreach work for thirty years. They have combined the design of effective practical programmes with research and evaluation of impact. This article explores…

In a recent survey of over 240 primary school children between the ages of 8 and 11, NUSTEM found that 75% of children said that they liked science and 63% said that they were good at science. However, when looking at the data by gender, there is a difference in enjoyment between girls and boys, with 71% of girls and 79% of boys saying that they…

A student's middle school science experience strongly impacts their future science, technology, engineering, and mathematics interest. The Japanese lesson study (JLS) model strengthens the student's experience through a research-based, collaborative, multistep, teaching-centered process focused on transforming local instructional practices. The…

To address the issue of gender disparity in participation in the physics state matriculation exam, a novel school visit program was designed. The program was facilitated by undergraduate university students of physics and related courses who visited schools providing lower secondary education and delivered a single-session workshop including…

Youth in rural communities have much to gain from afterschool and summer programs by receiving support for their well-being and academic growth they may not have otherwise. American Rescue Plan (ARP) has provided $122 billion in federal pandemic relief for schools and their efforts to address students' learning recovery. A lifeline for schools,…

Artificial intelligence (AI) technologies continue to revolutionize various sectors, including their incorporation into education, particularly in K-12 science education, which has become evidently significant. This paper presents a bibliometric analysis and systematic review that examines the incorporation of AI technologies in K-12 science…

A challenge in building the biomedical engineering human factors course at Malawi University of Business and Applied Sciences was integrating meaningful direct experiences with medical products. The instructor also noticed a significant gap between the topics in the course and their surrounding clinical context, a low-income setting. Recognizing…

This study investigated whether the Key Concepts in Science Project influenced the pedagogical development of Natural Science teachers. Grounded in social constructivism, emphasising collaborative learning and hands-on interaction, the study employed qualitative methods to collect empirical data. Through photographic evidence, field notes, and…

Integrating authentic research practices into introductory laboratory courses to prepare tomorrow's scientists has become increasingly prevalent over the past decade. However, an incomplete understanding of the nature of science (NOS) and authentic scientific inquiry (SI) precludes higher-level learning in undergraduate research experiences. In…
