Teaching chemistry necessitates hands-on activities to help students deeply understand chemistry concepts and relate scientific principles to daily life. However, constraints in accessing laboratory equipment and materials pose significant challenges for educators in conducting experiments. This paper proposes the development of a pH indicator gel…

Hydrogel is an interesting topic in polymer chemistry, which is closely related to daily life and advanced technology. In this paper, we report an activity to deliver hydrogel chemistry into middle school classrooms by undergraduates as a bridge between professors and students. During the activity, undergraduates act as a bridge to receive…

This exercise encompassed the construction and use of a microcontroller-based laser refractometer. The instrument, which does not require a high skill level to build, primarily consisted of a line laser, optical sensor, several 3-D printed parts and printed circuit boards, and a microcontroller development board. Construction and testing of the…

The chemistry of metal-organic frameworks (MOFs) has the potential to introduce high school and undergraduate students to the fundamental chemical principles of structure and bonding, enhance the development of skills in synthesis and crystal growth, and promote hands-on experience with gas capture and host-guest chemistry of emerging materials…

This report details the design of an online trilingual (English, French, and Portuguese) interactive virtual board game and its implementation at the Federal University of Ceará in Brazil. It was used as a fun alternative to assist chemistry and pharmacy undergraduate students in reviewing introductory concepts to organic reactions: enthalpy,…

This report describes an activity that helps organic chemistry students to better understand organic molecules as 3-dimensional objects. To accomplish this goal, the activity employs a unique three-way combination of analyzing computer-generated 3-dimensional renditions of open access X-ray crystallography data, building physical 3-dimensional…

The aim of this study was to examine the effect of the Common Knowledge Construction Model (CKCM) on the conceptual understanding of science teacher students about Radioactivity. CKCM was used. In order for the students to adapt the radioactivity subject, which they see as difficult and abstract, to daily life by knowledge structuring. This study…

As the trend for English as a medium of instruction (EMI) increases, teacher self-efficacy to teach the contents of their teaching materials in an EMI context has become one of the major challenges. This study investigated the self-efficacy of Indonesian non-ELT pre-service teachers to teach in an EMI context. Two Indonesian non-ELT pre-service…

Laboratory work in chemistry has been extensively researched in the last decade but the gap between research and practice is still broad. This "Perspective" shares 10 guiding principles relating to university laboratory education, drawing on research over the last decade. Written with an audience of practitioners in mind, the…

Retention and underrepresentation of diverse ethnic groups have been and continue to be problematic in the science, technology, engineering, and mathematics (STEM) disciplines in the United States. One foundational course that is required for all STEM majors is general chemistry. One way to increase retention and diversity in STEM majors is by…

Peer review is useful for providing students with formative feedback, yet it is used less frequently in STEM classrooms and for supporting writing-to-learn (WTL). While research indicates the benefits of incorporating peer review into classrooms, less research is focused on students' perceptions thereof. Such research is important as it speaks to…

The examination of students' motivation towards lessons is an important aspect of educational studies. The constructivist approach significantly impacts the improvement of students' motivation. The present study aims to examine the use of the 5E learning model with concept maps to support students' motivation and compare the 5E approach and the…

The most important learning objective in green chemistry education is the ability to identify the synthesis, process, or chemical that is least environmentally harmful. Existing metrics fall short for different reasons. Mass-based metrics fail to assess environmental harm, while life cycle assessment (LCA) is much too complex to insert into the…

Higher education continually seeks new approaches to support students with various learning needs. At present, Finland attempts to provide such support through accessibility and reasonable accommodation efforts, but students with learning disabilities may still encounter many barriers in their studies. One approach suggested to meet the needs of a…

Nitrate is a crucial parameter for assessing water quality, owing to its dual function in ecological systems. These functions can be beneficial or detrimental depending on whether nitrate concentrations are low or high, respectively. The ultraviolet spectrophotometric method (standard as 4500-NO[subscript 3]--B) is a classic method for determining…
