The particle-in-a-box experiment is a well-known method used to teach quantum mechanics concepts in physical chemistry laboratories for undergraduates. The investigation involves measuring the wavelength at maximum absorbance ([lambda subscript max]) of electronic transitions in the UV-vis spectrum and linking it to the box length. As the…

Active learning strategies engage students productively in the process of learning through problem-solving activities and discussions, over and above the routine method of listening passively to the instructor. This work highlights the redesign of a medicinal chemistry course by augmenting traditional lectures with active learning sessions in…

In this article, we discuss the replication of a forgotten chemical instrument in the context of undergraduate chemistry education. Together with students, we have attempted to replicate an eighteenth century "eudiometrical" procedure. Eudiometry was the practice of measuring the "goodness" of the air by looking at the volume…

Clicker-integrated instruction is the current innovation in teaching and learning. Several studies used this technology to investigate learning processes, while others mainly used it to asses for learning, facilitation of group discussion and students' participation. All applications require creativity and analytical thinking and very much…

This study investigates the impact of the language of instruction on assessment outcomes by comparing students' test performance in English (EMI) and Japanese Medium Instruction (JMI) courses. Data were collected from a university in Japan offering parallel Chemistry courses in Japanese and English as part of the same undergraduate curriculum. A…

This study examines how pre-service science teachers integrate technology into the design of learning activities, paying particular attention to types of technology integration, cognitive demand, scientific research skills, and TPACK. A mixed methods approach was used to analyze 49 learning activities designed by pre-service physics, chemistry,…

Purpose: This research aims to examine the pre-service teachers' learning when using STEM tasks with middle school students in a lesson study. Design/methodology/approach: This research adopted a qualitative methodology with an interpretative orientation. The participants are three pre-service teachers involved in a lesson study that took place in…

In the field of education, the integration of technology has grown, providing new opportunities for teaching and learning. One emerging technology that has gained attention is Artificial Intelligence (AI). This study investigates Lebanese chemistry teachers' knowledge and perceptions of AI, examining the benefits and challenges they anticipate or…

The ability to elucidate the structure of organic compounds from their nuclear magnetic resonance (NMR), infrared (IR), and mass spectrometry (MS) spectra is an essential skill, particularly for those engaged in the fields of synthetic and analytical organic chemistry. Spectral analysis constitutes a fundamental component of the curriculum for all…

To prepare students to use science knowledge in their later personal or professional lives, we must attend to what they believe it means to know and learn science (i.e., epistemology). Unfortunately, we have little understanding of how students' epistemologies shift and are stabilized as they navigate their science courses. Researchers have made…

Cognitive load studies are mostly centered on information on perceived cognitive load. Single-item subjective rating scales are the dominant measurement practice to investigate overall cognitive load. Usually, either invested mental effort or perceived task difficulty is used as an overall cognitive load measure. However, the extent to which the…

This study examines prevalent misconceptions among students regarding the fundamental concepts of acids and bases, which often arise during the learning process. This study aims to pinpoint misconceptions held by preservice science teachers in the realm of acids and bases; 117 university students from diverse educational backgrounds, enrolled in…

In the context of scholarly and scientific discourse, students often have to deal with graphic-visual modes of communication, which requires their ability to comprehend and utilize inscriptions, that is, scientific visual representations, to convey information effectively--what we call graphical literacy. Despite its pivotal role for training…

Climate change is one of the socio-environmental problems with the greatest complexity and media impact in the world. However, difficulties have been observed in its understanding. In this study, we worked on this social problem in the classroom through argumentation, from the evaluation of different statements made about the causes and…

Chemistry is a natural science that explores the composition, structure, and transformations of matter. Technological innovations have transformed both teaching methods and learning processes. To explore the transformative potential of virtual technologies in chemistry education, this study conducted a meta-analysis to assess their impact on…
