Laboratory skills assignments were developed as a novel approach to providing students with the opportunity to engage in hands-on laboratory skills development outside of the lab during the COVID-19 pandemic. Initially, the assignments were implemented within a second-year forensic chemistry course of 48 students and redesigned and modified to be…

Experiments serve different purposes in chemistry education ranging from illustrating a certain subject matter to providing data for school-based research projects. When students use these experiments to collect data and draw conclusions, it is important that these experiments are valid. In this study, a new experiment for the determination of the…

Common over-the-counter medicines can be an exciting entry point for introducing students to the interesting chemistries that they encounter in their daily lives. In this inquiry-based activity, students are tasked with using a list of given supplies and information about four medications (Aspirin, Tums, Pepto-Bismol, and Tylenol) to design three…

In this paper, a problem set activity focused on understanding and applying unsupervised and supervised chemometric methods for the analysis of biodiesel-diesel blended fuels is described. This problem set was utilized in two upper-level analytical elective courses aimed for junior and senior level students. The data set consists of peak areas…

It is crucial nowadays to predict in a fast and simple manner physical-chemical behaviors like, the size-dependent optical properties of gold nanospheres (Au NSs). The idea behind this experiment is trying to replace (as much as possible) robust and expensive microscopy techniques with UV-vis spectrophotometry and friendly simulations. Students…

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…
