Ludic-didactic material has systematically been proven to be a useful tool that enhances teaching and learning processes, at practically any educational level by reducing the stress level of students and creating a feeling of team spirit and trust. In chemistry courses, significant efforts have been made to improve the learning of intermolecular…

The COVID-19 outbreak represented a remarkable challenge in universities and colleges since it forced the transition from a face-to-face model in classrooms and laboratories to a remote, online model using computers, tablets, and cell phones. In Mexico and other Latin American countries, the return to educational activities was a slow-paced…

We conducted a study with introductory and upper-division physics students in a Mexican university to learn how students independently recognize the electric field's main characteristics in the electric field lines diagram and as a source or target representation in conversion processes. We used the theory of registers of semiotic representations…

The COVID pandemic forced teachers to be imaginative, especially with purely practical subjects such as laboratory chemistry. In the Universidad Nacional Autónoma de México, the first-semester chemistry laboratory of the Biology course was taught with a chemistry set to be used at home. The use of the kit was evaluated from the perspective of…

Anatomical sciences curricula have been under constant reform over the years, with many countries having to reduce course hours while trying to preserve laboratory time. In Mexico, schools have historically been autonomous and unregulated, and data regarding structure and methods are still lacking. A national survey was sent by the Mexican Society…

We describe a remote pedagogical approach based on chemical thinking to study metal-carbonyl complexes by analyzing simulated IR spectra. The proposed approach, implemented due to the COVID-19 pandemic, can be employed in classrooms that have very limited laboratory equipment for evaluating toxic metal-carbonyl compounds, as well as for…

This article explores the perception of gender inequality in science and the influencing factors. Data was collected through in-depth interviews with students belonging to a science club; we present it as a case study. This research sheds light on what high school and university students studying Science, Technology, Engineering, and Mathematics…

This paper analyses the current state of postcolonial and decolonial science teaching, based on a systematic review of the literature, with a special focus on the European context. It shows that currently, a very narrow view on postcolonial science teaching prevails, limiting its scope to former colonies. A total of 227 articles published…

The preschool level is often the first formal opportunity for children to experience science. There are many examples of appropriate experiments and scientific experiences aimed at young children, both in Mexico and around the world. Even the formal public preschool program in Mexico includes sections called Academic Training Topics, one of which…

Traditionally secondary studies on achievement on Programme for International Students Assessment (PISA) tests point to the significant impact of socioeconomic status and cultural backgrounds of families as well as the role of parental involvement, which in some cases has had a negative impact on achievement. For this article, a model of…

The following paper discusses the implementation of context-based learning to introduce the concepts associated to chemistry of cleaning in high-school students. The methodology proposed in Chemie im Kontext was followed and adapted with project-based learning to ensure key concepts were assimilated and related to students' everyday life. In such…

YouTube is one of the most known and used social networks among students in the world, and undergraduate chemistry students are no exception. Undeniably, YouTube can offer several advantages for complementing university lessons in an asynchronous manner. There are many chemistry channels available on the internet; however, they are mainly too…

Our study traces the pernicious whiteness of coloniality in elementary science classrooms in El Sur de Tejas, Aztlán. Our research method was an ethnographic case study that enabled us to explore participants' identities within bioregional contexts. In our findings, we emphasize the pernicious whiteness of coloniality via the participants'…

Actions taken to control the propagation of COVID-19 forced most activities to switch into an online environment. Education was no exception. In most of the cases the transition turned out well, and online education proved to be a good alternative to the traditional model. However, in the case of practical courses, the situation is quite different…

In this paper, we present a simulation of artificial selection of maize that can be used as a bridging case for the subsequent introduction of natural selection in school. The proposed simulation takes up essential biological elements but also has a cultural meaning for the inhabitants of some regions of Latin America. After implementing a test of…
