- Item¿Qué piensan los profesores de química en ejercicio acerca de la resolución de problemas científicos escolares y sobre las competencias de pensamiento científico?(2014) Quintanilla Gatica Mario Roberto; Joglar C.; Labarrere A.; Merino C.; Cuellar L.; Koponen I.This work derives from the theoretical and methodological orientations of a research program initiated in 2007 (FONDECYT 1070795, 1095149 and 1110598) whose purpose has been to identify and characterize the notions of science teachers and future teachers of school scientific problem solving and scientific thinking skills, as well as, the best strategy in which science education should be addressed in the school chemistry teaching. First-order results clearly indicated that their notions of scientific thinking skills and problem solving are fragmented, simple, minimally processed and even contradictory. The possible explanation for these results, we believe, is linked to a traditional representation of science and scientific knowledge products, and a simple and dogmatic instrumental image of teaching and learning chemistry.
- ItemThe matter, chemical reaction and thermodynamic models as structuring cores of a citizenship- oriented school chemistryLos modelos materia, reacción química y termodinámica como núcleos estructurantes de una química escolar orientada a la formación ciudadana(2021) Marzabal A.; Moreira P.; Cabello V.M.; Soto M.; Delgado V.; Izquierdo D.; Merino C.; Manrique F.; Cuellar L.© 2021 Facultad de Quimica, UNAM. All rights reserved.The present work proposes to consider models as structuring nuclei of school Chemistry school with the aim of overcoming the current curricular challenges and orienting chemistry education towards citizenship education. Through the analysis of the existing literature in the field of the curricular organization of School Chemistry, the matter, chemical reaction and thermodynamic models are identified and characterized as the nuclei of School Chemistry by identifying the conditions, entities, properties, activities and organization that student representations about material systems are expected to include, to reason about a set of relevant facts for citizen education.
