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…

NMR prediction using ChemDoodle, NMR calculation with Gaussian, and hands-on data collection using a benchtop NMR spectrometer were explored to assess their synergistic capacity in teaching NMR to organic chemistry students. Nine molecules representing functional groups commonly encountered in undergraduate organic chemistry were selected. Spectra…

Atomic-level visualizations serve as pivotal instructional tools in chemistry education, providing insights into the particulate level of matter, a dimension fundamental, yet typically invisible, in the study of chemistry. This research investigates how students' engagement with these visualizations influences their conceptual understanding of…

To address the changes that exist in the educational field, educators and curriculum developers are in constant search for innovations to keep up and foster alongside this timely educational revolution. In this case, this study emphasized the integration and parallel use of Phenomenon and Project based learning methods in High School General…

This article describes the design, implementation, and evaluation of the gamification of laboratory activities in a General Chemistry course at the Federal University of Ceará in Brazil. In the gamified laboratory, seven experiments traditionally performed in the course were transformed into ten missions, incorporating game elements such as…

This paper describes a digital application designed for learning Space Groups of Symmetry (SGS). It teaches how to recognize the operations performed by the symmetry elements, both point (or 2D) operators (proper and improper rotations, including mirroring, inversion, and other rotoinversions), and space (or 3D) operators (screw axes and glide…

Natural sciences can be difficult to grasp because physical and chemical phenomena can take place across time and length scales that are beyond the reach of human perception. This problem is particularly true for students attempting to learn about microfluidics, a discipline that involves intricate engineering methods and fluid phenomena that are…

Studies on the efficacy of the flipped classroom structure have become more prevalent in the chemistry education research literature over the past 10 years, and the body of research that has been compiled appears to indicate flipped classroom structures positively impact student learning outcomes relative to "teaching as usual"…

The assessment of student understanding, and of student reasoning skills more broadly, hinges upon the ability to elicit and interpret student-generated explanations. In practice, however, the explanations that students provide in response to traditional prompts do not always reveal as much about student reasoning as teachers and researchers in…

The global pandemic complicated both learning chemistry and, importantly, preparation for examinations. One of the problems which students face is the lack of teachers' attention, whereas the implementation of such distance learning technology as a chatbot represents one possible solution. The Chemist Bot was created specifically to help Russian…

Spin crossover (SCO) materials that switch between two different spin states, that is, the high spin (HS) and the low spin (LS) state, with very different optical, magnetic, and structural properties offer a unique platform to understand the consequences induced by the different electronic configurations of transition metal complexes. Due to the…
