The Making Introductory Courses Real while Online (MICRO) laboratory project was developed to meet the need for hands-on experiments, focused on topics in analytical chemistry, to be delivered safely remotely or in a socially distanced in-person lab. Unlike more traditional lab experiments, MICRO laboratories use only microgram or nanogram amounts…

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…

Effective usage of augmented reality (AR) depends on good integration into the learning environment. Based on a qualitative research approach, this study investigates the effects of using AR technologies in science education to support the effective use of AR. Students' experiences of AR were gathered using a prepared questionnaire form. Within…

The paper describes our research aimed to verify the durability of pupils' initial ideas and concepts on the issue of acids and bases. First, we mapped their existence among primary school pupils and then compared them with the ideas of secondary and university educated adults. It has been confirmed that some initial ideas are very lasting and are…

Metacognition is an important skill for undergraduate chemistry students, but there has been scant research investigating chemistry instructors' perspectives of metacognition and the development of their students' metacognition. Since undergraduate instructors have a wide influence over what happens in their courses, it is crucial to investigate…

Students commonly find specialist scientific language problematic. This study investigated developments in chemical language usage by six "non-traditional" students over the course of 1 to 4 years. The students participated in semi-structured interviews and were asked to explain specific chemical scenarios. Interviews were transcribed…

In the USA, Organic Chemistry I is a gateway course for undergraduate students seeking careers in medical- and health-related fields. Estimates of failure and withdrawal rates are approximately 40% at some large, public institutions and higher for specific segments of the student population, such as ethnic minorities, those of low socio-economic…

For some time now, chemistry has not had a good reputation in society. The population identifies this discipline with industries and pollution, while its positive contributions are usually ignored. This fear of chemistry may affect the opinion of society toward not only science, but also the scientific work itself. To assess the prevalence of this…

This research focuses on chemistry teachers' enacted pedagogical content knowledge (ePCK) in equilibrium in chemical reactions. The enactment dimension of this pedagogical content knowledge (PCK) encompasses enacted knowledge and skills as well as those embedded in practice concerning the Refined Consensus Model of PCK, the most recent PCK model…

To help students acquire mathematics and science knowledge and competencies, educators typically use multiple external representations (MERs). There has been considerable interest in examining ways to present, sequence, and combine MERs. One prominent approach is the concreteness fading sequence, which posits that instruction should start with…

This study took 'context' as a focal point in the context-based approach and its investigation was anchored on an analytical framework, which is composed of three dimensions of context: origins, intentions, and occasions. Content analysis was employed as the research methodology with 878 contexts identified from 96 copies of awarded chemistry…

Research suggests that systems thinking is beneficial to education and it has been proposed that training students using systems thinking techniques may enhance their abilities to understand and solve some of the global grand challenges that society currently faces as outlined by the United Nations Sustainable Development Goals. However, before…

Solid lipid nanoparticles (SLNs) are exciting nanoparticles used for transporting therapeutic drugs into an organism. In this laboratory work, a simple experiment is performed to introduce master's students into the field of nanotechnology, here applied to health including the applications in the healthcare/pharmaceutical and cosmetic industry.…

In contrast to a macroscopic solid, the color and spectroscopic properties of gold nanoparticles change with size. Here, we propose a teaching platform for high school students (hereafter defined as students, attending secondary school in Europe, preparatory high schools in the US, or any educational institution of a comparable level) that…

Infrared (IR) spectroscopy is a vibrational spectroscopic technique useful in chemical, pharmaceutical, and forensic sciences. It is essential to identify chemicals for reasons spanning from scientific research and academic practices to quality control in companies. However, in some university degrees, graduate students do not get the proficiency…
