Resumo: In this paper, we describe and characterize the solved problems concerning LR circuits in direct current that are present in twelve college textbooks commonly used in Argentine Republic. These books were examined through content analysis. The results indicate that in the analyzed sample, in general terms, the explicitness is deficient for the physic systems studied, the proposed hypotheses, their limits of validity and for the verbalized explanations. On the other hand, the displayed resolution of the problems has little coherence with the research work conducted, and this would not promote the scientific work in students. Based on these outcomes and implications for teaching, we noticed that reinforcing the conceptual issues in the classroom that are not enough emphasized in the textbooks is an avoidable task for Physics professors of the basic college cycle.

Los mismos se examinaron mediante el análisis de contenido. Los resultados obtenidos indican que en la muestra analizada, en términos generales, es deficiente la explicitación, tanto de los sistemas físicos en estudio, las hipótesis formuladas y los límites de validez de las mismas, como de las explicaciones verbalizadas. Por otro lado, la resolución mostrada de los problemas guarda escasa coherencia con el trabajo de investigación dirigida, lo cual no promovería el quehacer científico en los estudiantes. En función de estos resultados y como implicancia para la enseñanza, se deriva que es una tarea ineludible, para los docentes de Física del ciclo básico universitario, reforzar en el aula las cuestiones conceptuales que no se encuentran lo suficientemente enfatizadas en los mismos.Imprensa Universitária - UFSC2015-10-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2015v32n3p64010.5007/2175-7941.2015v32n3p640Caderno Brasileiro de Ensino de Física; v. 32 n. 3 (2015); 640-6622175-79411677-2334reponame:Caderno Brasileiro de Ensino de Física (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCspahttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2015v32n3p640/30632Copyright (c) 2015 Caderno Brasileiro de Ensino de Físicainfo:eu-repo/semantics/openAccessGiacosa, Norah SilvanaZang, ClaudiaGiorgi, SilviaMaidana, JorgeSuch, Alejandro2018-03-16T12:35:08Zoai:periodicos.ufsc.br:article/37440Revistahttp://www.periodicos.ufsc.br/index.php/fisicaPUBhttps://periodicos.ufsc.br/index.php/fisica/oaicbefisica@gmail.com||fscccef@fsc.ufsc.br|| cbefisica@gmail.com2175-79411677-2334opendoar:2018-03-16T12:35:08Caderno Brasileiro de Ensino de Física (Online) - Universidade Federal de Santa Catarina (UFSC)false
