Since ancient times, man has prepared medicines and used them in healing practices. Therefore, there has always been a great interest in the part of people in general and students in particular about medicines. The "Medicines, the Haute Couture of Pharmacy" summer camp has the objective to promote and improve the literacy in medicines…

This paper aimed to examine the changes in the representations of nature of science (NOS) in Chinese senior high school chemistry textbooks under the influence of the new curriculum ideas. The study was conducted based on an analytical framework in which the aspects of NOS, the approaches to address NOS, and the content relation of NOS aspects…

Women, ethnic minority, and less affluent groups are widely underrepresented in chemistry, a problem that is observed at all levels but begins before college matriculation takes place. The importance of representation and humanization of scientists is crucial. Despite limited progress over recent decades, poor visibility of role models from…

Scientists have always been fascinated by transient far-from-equilibrium systems. Since the (early) 1970s, there have been literature reports on the implementation of didactic experiments as a tool for attracting and stimulating students' and general public interest. In this work, a group of 12 high school students, supported by their chemistry…

The rapid evolution of Artificial Intelligence (AI) is profoundly shaping our society. Among various AI tools, ChatGPT stands out for its user-friendly nature and wide accessibility to the public. However, despite their countless potential benefits, these tools also face significant challenges, especially in sensitive areas like Education. In this…

We present herein a module of pigment synthesis experiments that could be adapted and implemented in a variety of curricular settings. At the conclusion of each of the past two spring terms at our high school, we offered a 4 day short course on the chemical synthesis of pigments used in art. As part of the course, our students synthesized four…

Writing instruments, such as pens, are ubiquitous in the classroom, but their functionality is largely for one purpose: they are used to represent ideas and record information on paper. However, by replacing the conventional ink in a pen with easy-to-synthesize conducting polymer-based inks, it is possible to change a simple writing utensil into a…

Comprehensive curricula are described for middle and high school classrooms built around the synthesis of biodegradable calcium alginate capsules prepared from food-safe chemicals. Experiments and activities question whether calcium alginate capsules are a viable alternative to single-use water bottles and consider what characteristics are…

This work aims to evaluate the evolution of chemical bonding concepts of high school students at public schools in southern Brazil. For this, we built the epistemological profile of each student who took part in a teaching-learning sequence (TLS) about this topic, based on the foundations of Bachelard's theory. Following the principles of the…

An application for visualizing the dynamic properties of an equimolar binary mixture of isotropic reactive particles is presented. By introducing a user selectable choice for the activation energy, the application is useful to demonstrate qualitatively that the reaction rate depends on the above choice and on temperature. The application is based…

Using Bruno Latour's framework of a "collective of humans and nonhumans", this paper presents an analysis of chemistry instruction in a high school curriculum and professional development setting to present the chemistry education community with a new way to think about reality and knowledge construction and, at the same time, to…

We present an experiment which was designed to assess the separation technique skills of the gifted high school students who attended the 50th International Chemistry Olympiad 2018. The procedure consists of two synthetic tasks and is also applicable for teaching undergraduates. The haloform reaction of 2-acetonaphthone with sodium hypochlorite in…

In this work, we introduce the VR[superscript 2]E[superscript 2]C system for Virtual Reality Remote Education for Experimental Chemistry. It aims to increase scientific literacy about remote education of theoretical and experimental chemistry among the public and high school students. It provides a laboratory option for students with disabilities…

In a normal year approximately 3 months pass between students taking their final examinations in high school or college and beginning an undergraduate course in chemistry. In the months prior to those examinations, students will usually have undertaken an extensive period of revision and consolidation of the key concepts learned throughout their…

Chemical reactions far from equilibrium can exhibit oscillatory behavior. Full understanding of this phenomenon is outside of the school curriculum. However, the importance of such processes in life sciences and peculiar spatial and temporal patterns accompanying the reactions can attract the attention of IB Diploma science students. They will…
