A teaching-learning sequence on a socio-scientific issue: Analysis and evaluation of its implementation in the classroom) This study investigates the effectiveness of a teaching-learning sequence on mining to improve understanding of the influences and interactions between a technology (mining) and society, also known as interactions between science, technology and society and nature of science. The aim of the study is to show the possibility of teaching and assessing the most innovative issues and aspects of scientific competence on understanding the nature of science, which are addressed in this study. The methodology uses a quasi-experimental, pre-post-test design with control group; the pre-post-test differences are the empirical indicators of improved understanding. The improvements are modest, as the empirical differences (pre-post and experimental-control group) are not large, though experimental group clearly over scores control. Further, the features that display relevant changes are identified. The contributions of the study are the standardized teaching learning sequence and assessment instrument, as they are functional and transferable, to allow researchers and teachers, teaching and assessing the nature of science in the classroom.
Este estudio investiga la eficacia de una secuencia de enseñanza-aprendizaje acerca de la minería sobre la comprensión de la naturaleza de la ciencia y la tecnología, en este caso centrada aspectos de la influencia de la minería sobre la sociedad y viceversa, la influencia de la sociedad sobre las tecnologías y explotaciones mineras. La investigación se ajusta a un diseño pre-posttest, donde la aplicación de la secuencia de aprendizaje tiene lugar entre ambas evaluaciones, inicial y final, cuyas diferencias mutuas son los indicadores de la eficacia de la enseñanza. Los resultados obtenidos son modestos, pues aunque se identifican algunas áreas de mejora, también existen otras áreas donde no se produce mejora y las diferencias de mejora observadas son pequeñas. El estudio presenta una estandarización de la evaluación que puede servir para comparar efectos de distintas secuencias didácticas o para comparar investigaciones diferentes.
