3D printers have facilitated a wealth of 3D printed molecular models illustrating key structural concepts for student learning. However, general adoption of 3D printed models in the organic chemistry classroom proceeds slowly as the majority of consumer-grade 3D (fused deposition modeling (FDM) and resin) printers are inherently monochromatic,…

Flame Emission Spectroscopy (FES) is a powerful analytical technique widely used for identifying and quantifying elements in various samples. In this laboratory experiment, undergraduate students were introduced to FES and its significance in analytical chemistry. The experiment aimed to provide students with hands-on experience in constructing…

A variety of methods have been used to analyze the kinetics of various processes related to the Diet Coke and Mentos experiment (also known as the soda geyser). However, none of these previous reports has undertaken a quantitative exploration of the dynamics of the creation and collapse of the soda geyser itself. We have therefore devised a method…

A new perspective on chemistry learning could be the optimal learning moment of view based on flow theory. Optimal learning moments (OLMs) that occur when students experience high levels of interest, challenge, and skill at the same time were investigated in this study. Participants of the study were 47 pre-service science teachers. Data were…

The continuous underrepresentation of the Latinx population in STEM fields and careers requires urgent attention. This study addresses this issue by designing and implementing a science curriculum based on culturally relevant and translanguaging pedagogies. Focusing on chemical and physical reactions, the curriculum was implemented in two…

A Doctor of Philosophy (PhD) is defined as the highest achievable degree and represents the completion of a specialized mentored project. Concerningly, graduate programs are structured in ways that can lead to inequities that exclude graduate students based on race, class, gender, ability, and additional intersecting social locations. Drawing from…

Nowadays, discussing global environmental issues has become regularly included in STEM-based higher education, emphasizing the importance of the youth in finding "ad hoc" solutions for the climate crisis. One of the most commonly applied strategies is promoting sustainable choices among students, especially linked to their lifestyle…

In upper-secondary chemistry education, the concept of 'Amount of Substance' occupies a central position within the computation framework. However, comprehending this concept often poses a challenge for students. To address this issue, our study aimed to design and implement a computation skills test to assess the varying levels of students'…

This study aims to investigate the applicability and effectiveness of the peer instruction method on teaching the subject of acids and bases at the 12th-grade level. In addition, it aims to determine the effect of peer instruction on students' attitudes towards chemistry and in-class discussion, and to examine students' opinions regarding peer…

Now days, the level of students' engagement in secondary school chemistry is low. The aim of this study was then to enhance student chemistry engagement through simulation-integrated 7E context-based instructional strategy and compared its efficacy with 7E context-based instructional strategy, simulation-integrated conventional teaching approach,…

Students who learn the language of instruction as an additional language represent a heterogeneous group with varying linguistic and cultural backgrounds, contributing to classroom diversity. Because of the manifold challenges these students encounter while learning the language of instruction, additional barriers arise for them when engaging in…

The COVID-19 pandemic has compelled innovations in science teaching and learning, such as blending online sessions with conventional face-to-face classes. We developed and validated the Blended Laboratory and E-learning iNstructional Design (BLEND) model for university-level remote laboratory sessions (RLS) to respond to the fluctuating…

There is widespread interest in diversifying and decolonizing the chemistry curricula in higher education. However, this is not reflected in the curricula taught to students prior to coming to university. We describe the results of an online survey of 185 secondary school/college teachers and students (>18 years) and, separately, 79 members of…

Most chemistry students struggle with interpreting and understanding NMR (nuclear magnetic resonance) spectra and the general concepts of NMR spectroscopy. NMR spectroscopy seems to be difficult to both teach and learn. Therefore, the corresponding courses should be investigated in more detail. We conducted a survey with N = 39 German university…

Hands-on experiments and teacher-based demonstrations are two standard teaching methods in secondary school when teaching chemistry in the laboratory. The available literature on these two teaching methods focuses on students' academic achievement. Most of this literature reports inconsistent results, and few studies examined teachers' and…
