The Databank of Dynamics Trajectories (DDT, notthatddt.org) was established to assist students in visualizing the dynamical behaviors occurring during chemical reactions and conformational changes, with a focus on processes taught in introductory organic chemistry classes. Animations of reacting molecules created using "ab initio"…

Molecular modeling can be used as an excellent teaching method for providing better insight into the mechanism of free radical reactions. Due to its highly visual nature, it can affect and improve students' perception and visualization of chemistry phenomena. The majority of chemistry students will know how to represent a reaction between two free…

Nonlinear chemical reactions produce interesting chemohydrodynamic patterns in an unstirred medium, which act as interesting demonstrations to display the novel phenomena in a nonequilibrium chemical system. Here, we report new outreach experiments: pH chemohydrodynamic patterns modulated by sodium polyacrylate in the bromate-sulfite-ferrocyanide…

Raman scattering spectroscopies are important analytical tools in modern chemistry. Here, we describe the construction of the unamplified Raman scattering analysis (URSA) instrument: an inexpensive, open-table Raman spectrometer that uses a 532 nm diode-pumped laser as a light source. Upon application of this spectrometer to DNA extracted from…

Academic journals, including the "Journal of Chemical Education," are repositories of individual works from communities of scholars. Often the use of information from journals is discrete, operating at the level of the individual article. Indeed, the use of search engines and rapid electronic delivery of individual articles as a PDF file…

Peer-led team learning is a socially mediated pedagogy where trained peer leaders, students who have completed a course, return to lead students in groups within a targeted course. The effect of peer-led team learning to improve student success in chemistry has been extensively documented but it is unclear if it is just as effective at…

Many large introductory classes are taught in stadium-style classrooms, which makes group work more difficult due to the room layout and immobile seating. These classrooms may create challenges for an instructor who wants to monitor student engagement because the layouts make it difficult to interact with the students as they work. Student…

Intellectual demands of learning outcomes in the intended curriculum have always been a concern across the field of science education. In particular, the representation of those learning outcomes stipulated by the intended curriculum in science textbooks has become a big issue for both science curriculum studies and science teaching practice. To…

Effective organic chemistry instruction necessitates an adaptable approach that accommodates varied learning styles and improves students' comprehension of concepts. To attain this goal, teachers may employ visualization, molecular modeling, and interactive software to explain three-dimensional structures and spatial interactions. Thus, the…

There is increasing interest in the use of artificial intelligence technologies, which have become a transformative force in the field of education, in educational fields that include subject areas that support lifelong learning, such as science and chemistry education. In this study, a systematic review was conducted on the use and effects of…

Enhancing the effectiveness of short-duration teacher workshops is critical for improving science teaching and learning, particularly in the developing world. While project-based learning is known to enhance knowledge usability, its feasibility and optimal design within short-duration teacher workshops in the developing world is unclear. This…

This study aims to determine the effect of the STEM-based learning model on collaboration skills and determine the effective contribution of the STEM-based learning model to collaboration skills in the chemistry subject of buffer solution material. This study uses a quantitative quasi-experimental study with a posttest only with control group…

Significant equity gaps in introductory STEM courses create barriers in the STEM pathway. The current study investigated the impact of equitable access to course resources in the form of different e-textbooks in an introductory chemistry course. We aimed to determine if using a free textbook and/or an interactive textbook enhances students'…

Think-aloud protocols are a standard method to study self-regulated learning (SRL) during learning by problem-solving. Advances in automated transcription and large language models (LLMs) have automated the transcription and labeling of SRL in these protocols, reducing manual effort. However, while effective in many emerging applications, previous…

Teaching redox reactions requires careful investigation as learners often display a range of misconceptions, particularly in connecting the chemistry levels of representation: macroscopic, sub-microscopic, and symbolic. This study explores teachers' teaching strategies, opportunities, and challenges when developing conceptual understanding of…
