Moreira, Patricia; Marzabal, Ainoa; Talanquer, Vicente – Chemistry Education Research and Practice, 2019
The central goal of this research study was to characterise the different types of reasoning manifested by high school chemistry students when building initial written explanations of a natural phenomenon. In particular, our study participants were asked to explain why a mixture of water and alcohol works as an antifreeze. Data collected in the…

Moreira, Patricia; Marzabal, Ainoa; Talanquer, Vicente – Chemistry Education Research and Practice, 2019
Understanding how chemistry teachers' interventions shape the reasoning that students express after a lesson is critical to support prospective and in-service teachers as they work with students' ideas in the classroom. In this qualitative research study, we analysed changes in the reasoning expressed by 10th grade students in a Chilean school in…

Montes, L. H.; Ferreira, R. A.; Rodríguez, C. – Chemistry Education Research and Practice, 2018
Research into attitudes towards chemistry in Latin America and indeed towards science in general is very limited. The present study aimed to adapt and validate a shortened version of Bauer's Attitude toward the Subject of Chemistry Inventory version 2 (ASCIv2) for use in a Latin American context. It also explored attitudes towards chemistry of…

Ollino, Mario; Aldoney, Jenny; Domínguez, Ana M.; Merino, Cristian – Chemistry Education Research and Practice, 2018
This study presents a method for teaching the subject of chemical equilibrium in which students engage in self-learning mediated by the use of a new multimedia animation (SEQ-alfa©). This method is presented together with evidence supporting its advantages. At a microscopic level, the simulator shows the mutual transformation of A molecules into B…

Poblete, Joaquin Castillo; Rojas, Rocio Ogaz; Merino, Cristian; Quiroz, Waldo – Chemistry Education Research and Practice, 2016
Considering the relevance of thermodynamics to the scientific discipline of chemistry and the curriculum of the Western school system, the philosophical system of Mario Bunge, particularly his ontology and epistemology, is used herein to analyze the presentation of the first law of thermodynamics in 15 school and university textbooks. The…
